摘要： An optical reproducing apparatus has a dual grating provided with a substrate, a first diffraction grating and a second diffraction grating. The first grating receives an incident light reflected from an optical recording medium and separates the reflected light into a first transmitted light and a first diffracted light. The second grating receives the first transmitted light and the first diffracted light through the substrate and discharges a second diffracted light and a second transmitted light. A tracking error signal detector detects a tracking error signal by receiving one of the second transmitted light and the second diffracted light. A focusing error signal detector detects a focusing error signal be receiving the other of the second transmitted light and the second diffracted light.

摘要： In an apparatus for recording and reproducing optical information, light emitted from a laser beam source is irradiated to an optical information recording medium to record the optical information and the light reflected from the recording medium is guided to a signal detecting optical system to detect tracking and focusing error signals and a reproducing signal. The apparatus comprises a dual grading arranged through a detecting lens on an optical path on which the light reflected from the recording medium is guided to the optical system, the dual grating having diffraction gratings formed at an equal pitch on the front and rear faces of a substrate, a refractive index of the substrate being greater than the refractive indexes of the diffraction gratings; and a photodetector for detecting light transmitted through the dual grating. The dual grating may have diffraction gratings respectively formed at equal and irregular pitches on both faces of a substrate. The dual grating may have a front face grating formed on a first incident side of the reflected light and a rear face grating formed on the side of a substrate opposite to the first incident side; the front face grating having a pitch smaller than that of the rear face grating; an incident angle of the reflected light with respect to the front face grating being set to be greater than a Bragg angle with respect to the front face grating.

摘要： The invention prevents an assembling structure of the plated resin article from generation of squeak noise with suppressing increase in costs. The assembling structure includes a first member including a first resin molded article at least a first surface of which is coated by a coating film; and a second member including a second resin molded article at least a second surface of which is plated by a plating film. The first member and the second member are assembled so as to frictionally contact at the coating of the first surface and the plating film of the second surface; and the coating film includes a particle made from a fluorine resin. The generation of squeak noise can be suppressed with maintaining the physical properties of the coating film, such as gloss and re-coating ability.

摘要： A digital radio telephone system for establishing communications between a main unit and a sub unit and between a plurality sub units. The system includes a main unit and a plurality of sub units. In order to establish communications with a sub unit, a calling signal including the sub unit extension number is first sent through the main unit to the sub unit. If the sub unit corresponding to an extension number in the calling signal is available, a calling acceptable signal is transmitted by the sub unit. The main unit includes an extension number multiplexer which multiplexes a plurality of sub unit extension numbers into one calling signal. Therefore, a calling signal from the main unit and calling signals from a plurality of sub units are multiplexed (combined) into a single calling signal. The main unit need only transmit a single multiplexed calling signal instead of a plurality of individual calling signals to each sub unit.
摘要翻译：一种用于在主单元和子单元之间以及在多个子单元之间建立通信的数字无线电话系统。该系统包括主单元和多个子单元。为了与子单元建立通信，首先通过主单元将包括子单元分机号码的呼叫信号发送到子单元。如果与呼叫信号中的分机号相对应的子单元可用，则子单元发送呼叫可接受信号。主单元包括分机号多路复用器，其将多个子单元分机号码复用为一个呼叫信号。因此，来自主单元的呼叫信号和来自多个子单元的呼叫信号被多路复用（组合）成单个呼叫信号。主单元仅需要发送单个多路复用呼叫信号而不是将多个单独呼叫信号发送到每个子单元。
