摘要:
A split type optical pick-up device suitable for use in an optical disc memory system has a two-part structure: stationary and movable optical systems which are provided separately. The stationary optical system includes a semiconductor laser for emitting a laser beam which is received by a deflecting member of the movable optical system. The thus deflected laser beam is focused onto an optical disc by an objective lens. The light reflecting from the optical disc passes through the objective lens in the reversed direction and also through the deflecting member to impinge upon a tracking error detector which is also provided in the movable optical system. Because of the provision of the tracking error detector in the movable optical system, there will be produced no offset in a tracking signal generated by the tracking error detector.

A split type optical pick-up device suitable for use in an optical disc memory system has a two-part structure: stationary and movable optical systems which are provided separately. The stationary optical system includes a semiconductor laser for emitting a laser beam which is received by a deflecting member of the movable optical system. The thus deflected laser beam is focused onto an optical disc by an objective lens. The light reflected from the optical disc passes through the objective lens in the reverse direction and also through the deflecting member to impinge upon a tracking error detector which is also provided in the movable optical system. The deflecting member has differnt rates of transmission for p and s polarized light for the light reflected from the optical disc such that the s polarized light is reflected toward the stationary optical system as much as possible so as not to waste the s polarized light, which defines a component of an information signal to be reproduced in the stationary optical system. Because of the provision of the tracking error detector in the movable optical system, there will be produced no offset in a tracking signal generated by the tracking error detector, and since the deflecting member reflects the s polarized light as much as possible, there is obtained an enhanced S/N ratio.
摘要:
A heating wire is wound around a casing within which a sensor body is placed. Thermo-sensitive switch means is connected to the heating wire, which is responsive to the temperature within the casing to control the rate at which electric current is supplied to the heating wire so as to keep the temperature at a constant value. The casing may be placed within an airtight housing which is made of an insulating material. A further heating wire may be arranged on the inner wall of the airtight housing, which is controlled by further thermo-sensitive switch means so as to keep the temperature within the housing at a constant value.

A first transmitting unit transmits print hold information to other printing apparatus connected on a downstream side in a data transmitting direction. A second transmitting unit transmits printing data from a host apparatus to the other printing apparatus. A third transmitting unit transmits page deletion information to the other printing apparatus every time a page is printed. When a printing condition cannot be satisfied, a fourth transmitting unit transmits print-disable information to the other printing apparatus, and releases a hold of the printing process in the other printing apparatus according to the print-disable information.

A thin-film transistor substrate in which an aluminum alloy film composing a source/drain wiring is directly connected with a transparent electrode. The thin-film transistor substrate includes a gate wiring, and source wiring and drain wiring, the gate wiring and the source and drain wiring being arranged orthogonally to each other. The single-layer aluminum alloy film composing the gate wiring and the single-layer aluminum alloy film composing the source wiring and the drain wiring are the same in composition. Furthermore, display devices can be mounted with the above thin-film transistor substrates.

A source/drain electrode is used in a thin-film transistor substrate containing a substrate, a thin-film transistor semiconductor layer, source/drain electrodes, and a transparent picture electrode. The source/drain electrode includes a nitrogen-containing layer and a thin film of pure aluminum or an aluminum alloy. Nitrogen of the nitrogen-containing layer binds to silicon of the thin-film transistor semiconductor layer, and the thin film of pure aluminum or aluminum alloy is connected to the thin-film transistor semiconductor layer through the nitrogen-containing layer.

A medium judgment program is recorded on an information recording medium. The program causes a computer to judge whether the medium is authorized. The judgment may be based on information on a unique value preformed in the medium in regard to each of the media. If the computer determines that the information recording medium is right or authorized, the program permits the computer to reproduce a main program. The main program is different than the medium judgment program. If the computer determines that the information recording medium is wrong or unauthorized, the computer is prohibited from reproducing the main program.

A display device includes an insulating substrate, a thin-film transistor arranged on the insulating substrate, a pixel electrode including a transparent electrode, and an aluminum alloy film as a connection wiring section for electrically connecting between the thin-film transistor and the pixel electrode. The aluminum alloy film is a multilayer aluminum alloy film including an aluminum alloy layer containing no nitrogen, and another aluminum alloy layer being arranged on the first layer and containing nitrogen. The nitrogen-containing layer ensures corrosion resistance against an alkaline solution. The nitrogen-containing aluminum alloy layer has been removed at least in a connection area with the pixel electrode so as to allow the pixel electrode to be directly connected to the first aluminum alloy layer.
