State-owned Enterprise
A state-owned enterprise (SOE) is a business entity created or owned by a national or local government, either through an executive order or legislation. SOEs aim to generate profit for the government, prevent private sector monopolies, provide goods at lower prices, implement government policies, or serve remote areas where private businesses are scarce. The government typically holds full or majority ownership and oversees operations. SOEs have a distinct legal structure, with financial and developmental goals, like making services more accessible while earning profit (such as a state railway). They can be considered as government-affiliated entities designed to meet commercial and state capitalist objectives. Terminology The terminology around the term state-owned enterprise is murky. All three words in the term are challenged and subject to interpretation. First, it is debatable what the term "state" implies (e.g., it is unclear whether municipally owned corporations and ente ...

Non-renewable Resource Companies Established In 1958
A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. An example is carbon-based fossil fuels. The original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas. Earth minerals and metal ores, fossil fuels (coal, petroleum, natural gas) and groundwater in certain aquifers are all considered non-renewable resources, though individual elements are always conserved (except in nuclear reactions, nuclear decay or atmospheric escape). Conversely, resources such as timber (when harvested sustainably) and wind (used to power energy conversion systems) are considered renewable resources, largely because their localized replenishment can also occur within human lifespans. Earth minerals and metal ores Earth minerals and metal ores are examples of non-renewable resources. The metals themselves are present in vast amounts in E ...

Manufacturing Companies Established In 1958
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of the secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final p ...

Companies Based In Kunming
A company, abbreviated as co., is a legal entity representing an association of legal people, whether natural, juridical or a mixture of both, with a specific objective. Company members share a common purpose and unite to achieve specific, declared goals. Over time, companies have evolved to have the following features: "separate legal personality, limited liability, transferable shares, investor ownership, and a managerial hierarchy". The company, as an entity, was created by the state which granted the privilege of incorporation. Companies take various forms, such as: * voluntary associations, which may include nonprofit organizations * business entities, whose aim is to generate sales, revenue, and profit * financial entities and banks * programs or educational institutions A company can be created as a legal person so that the company itself has limited liability as members perform or fail to discharge their duties according to the publicly declared incorporation pu ...

Government-owned Companies Of China
State ownership, also called public ownership or government ownership, is the ownership of an industry, asset, property, or enterprise by the national government of a country or state, or a public body representing a community, as opposed to an individual or private party. Public ownership specifically refers to industries selling goods and services to consumers and differs from public goods and government services financed out of a government's general budget. Public ownership can take place at the national, regional, local, or municipal levels of government; or can refer to non-governmental public ownership vested in autonomous public enterprises. Public ownership is one of the three major forms of property ownership, differentiated from private, collective/cooperative, and common ownership. In market-based economies, state-owned assets are often managed and operated as joint-stock corporations with a government owning all or a controlling stake of the company' ...

Smelting
Smelting is a process of applying heat and a chemical reducing agent to an ore to extract a desired base metal product. It is a form of extractive metallurgy that is used to obtain many metals such as iron-making, iron, copper extraction, copper, silver mining#Ore processing, silver, tin, lead smelting, lead and zinc smelting, zinc. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal behind. The reducing agent is commonly a fossil-fuel source of carbon, such as carbon monoxide from incomplete combustion of coke (fuel), coke—or, in earlier times, of charcoal. The oxygen in the ore binds to carbon at high temperatures, as the Chemical energy, chemical potential energy of the bonds in carbon dioxide () is lower than that of the bonds in the ore. Sulfide ores such as those commonly used to obtain copper, zinc or lead, are roasting (metallurgy), roasted before smelting in order to convert the sulfid ...

Metal Companies Of China
A metal () is a material that, when polished or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. These properties are all associated with having electrons available at the Fermi level, as against nonmetallic materials which do not. Metals are typically ductile (can be drawn into a wire) and malleable (can be shaped via hammering or pressing). A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride. The general science of metals is called metallurgy, a subtopic of materials science; aspects of the electronic and thermal properties are also within the scope of condensed matter physics and solid-state chemistry, it is a multidisciplinary topic. In colloquial use materials such as steel alloys are referred to as metals, while others such as polymers, wood or ceramics are nonmetallic materials. A metal conducts electricity at a temperature of absolute zero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Motor Manufacturing Industry In China
China's electric motor industry has been developed for 60 years. Most manufacturers produce low power and small-size motors. Small motor manufacturers are mostly located in Zhejiang province, Fujian province, and Guangdong province. Only a few motor manufacturers produces high power and large-size motors, for example Wannan Motor and Sogears Motor. High power and large-size motors are often used in rolling mills, etc. In the last, ABB and Siemens large-size motors took a large market shares in China. However, ABB and Simens motor often have very high sale prices so that some rolling mills cannot afford. They need domestic large-size motors instead of ABB motors. Currently, those rolling mills can buy from domestic motor manufacturers which can produce such large-size motors. Government policies In 2010, the Ministry of Industry and Information Technology issued its "Interim Measures for Accreditation and Management of Remanufactured Product" to standardize the electric motor in ...

Rotor (electric)
The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor's axis.Staff. "Understanding Alternators. What Is an Alternator and How Does It Work." N.p., n.d. Web. 24 November 2014 . Early development An early example of electromagnetic rotation was the first rotary machine built by Ányos Jedlik with electromagnets and a commutator, in 1826-27. Other pioneers in the field of electricity include Hippolyte Pixii who built an alternating current generator in 1832, and William Ritchie's construction of an electromagnetic generator with four rotor coils, a commutator and brushes, also in 1832. Development quickly included more useful applications such as Moritz Hermann Jacobi's motor that could lift 10 to 12 pounds with a speed of one foot per second, about 15 watts of mechanical power in 1834.

Holding Company
A holding company is a company whose primary business is holding a controlling interest in the Security (finance), securities of other companies. A holding company usually does not produce goods or services itself. Its purpose is to own Share capital, stock of other companies to create a corporate group. In some jurisdictions around the world, holding companies are called parent companies, which, besides holding Share capital, stock in other companies, can conduct trade and other business activities themselves. Holding companies reduce risk for the shareholders, and can permit the ownership and control of a number of different companies. ''The New York Times'' uses the term ''parent holding company''. Holding companies can be subsidiaries in a Subsidiary#Tiered subsidiaries, tiered structure. Holding companies are also created to hold assets such as intellectual property or trade secrets, that are protected from the operating company. That creates a smaller risk when it comes ...
