Nidec Copal Corporation
The , or Copal, is a Japanese manufacturer of optical, electronic and mechanical equipment, primarily for the photographic industry. It has been a subsidiary of Nidec Corporation since 1998, and was formerly known as the Copal Corporation. The company began operation in 1946, with small-scale production of photographic shutters; these are still one of the company's best-known products. In the 1960s the company began producing the well-known Copal Square vertically travelling metal blade focal plane shutter, which was very successful and was used in cameras by many prominent manufacturers. The ''Copal Square-S'', for example used in the Konica T3s (1973-1978) and the Nikkormat FT, is very reliable. It works over a wide temperature range. The electronically controlled Copal ''Square E'' (1968) was used in the Yashica TL Electro X, the Canon EF, the Nikkormat EL. For Minolta XE and the Leica R3 The Leica R3 was a 35mm SLR camera by Leica and the first model of their R s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Photographic
Photography is the art, application, and practice of creating images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. A person who operates a camera to capture or take photographs is called a photographer, while the captured image, also known as a photograph, is the result produced by the camera. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The ...

Focal Plane Shutter
In camera design, a focal-plane shutter (FPS) is a type of photographic shutter (photography), shutter that is positioned immediately in front of the focal plane of the camera, that is, right in front of the photographic film or image sensor. Two-curtain shutters The traditional type of focal-plane Shutter (photography), shutter in 35 mm cameras, pioneered by Leitz for use in its Leica cameras, uses two shutter curtains, made of opaque rubberised fabric, that run horizontally across the film plane. For slower shutter speeds, the first curtain opens (usually) from right to left, and after the required time with the shutter open, the second curtain closes the aperture in the same direction. When the shutter is cocked again the shutter curtains are moved back to their starting positions, ready to be released. Focal-plane shutter at low speed ''Figure 1:'' The black rectangle represents the frame aperture through which the exposure is made. It is currently covered by the ...

Nikkormat
Nikkormat (Nikomat in Japan) was a brand of cameras produced by the Japanese optics company Nippon Kogaku K. K., as a consumer version of the professional Nikon brand. Nikkormat cameras, produced from 1965 until 1978, were simpler and more affordable than Nikon-branded cameras, but accepted the same lenses as the Nikon F series cameras. Note on the Nikkormat metering system The light meter indicates current whose value depends on the amount of light, and three user settings: aperture, shutter speed, and film sensitivity (film speed). In many cameras the three user settings each have a separate resistor with a moving contact. In the Nikkormat there is only a single resistor and a single moving contact: the resistor is on one ring and the contact on another of the concentric rings around the lens mount. The film sensitivity (speed) and the shutter speed combine their values on one ring, while the aperture determines the relative position of the second ring. Using only one m ...

Minolta XE
The Minolta XE, known as the XE-1 in Europe and the XE-7 in North America, is a manual focus, 135 film, 35 mm single-lens reflex camera produced by Minolta of Japan between 1974 and 1977. It was developed in collaboration with Leica Camera and has many similarities to the Leica R3. The XE uses a Ernst Leitz GmbH, Leitz-Nidec Copal Corporation, Copal electronic, vertically traveling, metal blade focal plane shutter supporting exposure times of 1/1000 of a second to four seconds, plus bulb setting. In aperture priority auto-exposure mode, the shutter speed is varied steplessly; in manual mode, the shutter speeds are selected in whole stop increments. The camera has a very short shutter lag of about 38ms, among the best for an SLR regardless of manufacturer.

Nikon F4
The Nikon F4 is a 35 mm autofocus (AF) single lens reflex (SLR) film camera, introduced in 1988 as the next generation in Nikon's line of F series professional cameras. With industrial design by Giorgetto Giugiaro, the F4 was the first professional Nikon to feature a practical autofocus system. The F4 is able to accept any of Nikon's manual focus (MF) or AF lenses from 1959 to the present day, including the two F3AF lenses (in Autofocus mode). The F4 succeeded the F3, a manual focus camera introduced in 1980 but outlasting the F4 as it stayed in production until 2001. Nikon introduced its next flagship model, the F5, in 1996. All F4 models were discontinued soon after, in May 1997. Features The F4 introduced many Nikon owners to autofocus (as well as focus tracking), and was the first professional Nikon to utilize a vertical-travel metal-blade shutter (with shutter balancer to minimize noise and camera bounce). The shutter was a further developed Copal Square. As a full ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tablet Computer
A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, have similar capabilities, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens or larger, measured diagonally, and may not support access to a cellular network. Unlike laptops (which have traditionally run off operating systems usually designed for desktops), tablets usually run mobile operating systems, alongside smartphones. The touchscreen display is operated by Gesture recognition, gestures executed by finger or digital pen (stylus), instead of the Computer mouse, mouse, touchpad, and Keyboard (computing), keyboard of larger computers. Portable computers can be classified according ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manufacturing Companies Of Japan
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 produ ...
