Title: Fsk demodulating circuit
Inventor: OISHI YASUYUKI
IPC: C08F8/28
Filed: 1987-08-29
Abstract: PURPOSE:To eliminate a phase shifter on the circuit constitution of a phase detector and to decrease the generation of an error based on a noise, etc., by extracting the phase information of the four points of the rising and falling edges of a signal and executing a majority processing concerning a result. CONSTITUTION:The titled circuit provides a phase detecting means 1 to obtain two signal outputs to be orthogonalized, whose phase relation is changed in correspondence to a modulating code by multiplying two carrier waves to be mutually orthogonalized to an FSK modulating wave, sampling means 21-24 to obtain four binary signals by respectively sampling one signal value with the rising and falling edges of the other one of the two signal outputs and a majority deciding means 3 to execute the majority decision of the four binary signals and to generate the output of the decided result. A holding means 4 is also provided to output the output of the decided result as a demodulating signal when the majority decision is executed and to hold a just preceding decided value when '1' and '0' are in the same number in the majority decision. Thus, since the phase shifter is not used on the circuit constitution of the phase detector, realization goes to be easy and the generation of the error due to the noise, etc., is decreased.

Abstract: PURPOSE: To improve an SN ratio in a photo-detector output by making a first incident angle of the laser beam from a laser source reflecting on a separation surface of a beam splitter to a boundary reflection surface in the beam splitter at a non-right angle. CONSTITUTION: This device is provided with a beam splitter with a separation surface which transmits at least a part of a laser beam 26 coming from a laser light source and reflects the return beam 38, which is the part of the transmitted beam and is reflected from a recording surface 20, in the reverse direction of the laser light source, and a photodetector 40 which receives the return light beam coming through the beam splitter 30.

Title: Pressure control device
Inventor: FURUSATO KOUSUKE
IPC: G05D16/00
Filed: 1983-11-16
Abstract: PURPOSE:To prevent a safety valve from being actuated by increasing the opening degree of a pressure regulating valve gradually when the secondary pressure of the pressure regulating valve is abnormally increased at the opening of a shut off valve. CONSTITUTION:At an emergency time, an electromagnetic valve 7 is actuated and the shut off valve 5 is closed. A switching valve 17 sets up a conduit 19 to atmospheric pressure, so that the pressure control valve 10 is closed and feeding of fluid to a machine device 1 is interrupted. When the valve 7 is energized to feed the fluid to the device 1, the valve 5 is opened and the pressure P1 of a conduit 3 is made equal to the pressure P0 of a conduit 2. At the time, the switching valve 17 is turned to a switching position 17b and the valve 10 starts its pressure control operation on the basis of the actuation of a pressure controller 13 corresponding to the output of a pressure transmitter 11. Consequently, the valve 10 is gradually opened from the fully closed status and the pressure P2 of a conduit 4 reaches a set value Ps. Thus, the safety valve 15 is prevented from being actuated.

Filed: 1989-08-25
Abstract: PURPOSE:To facilitate the formation of a stress relieving part and to improve productivity by forming a fine glass particle layer on a substrate, incising thin sheets perpendicularly into the fine glass particle layer to remove a desired part, then subjecting the layer to a heating treatment. CONSTITUTION:Fine glass particles are injected from a torch onto the substrate 11 to form the fine glass particle layer 12 of a prescribed thickness. The thin sheets 14 made into a blade shape are perpendicularly incised onto the layer 12 and thereafter, the sheets 14 are horizontally moved on the substrate 11 to remove the layer 13 exclusive of the prescribed partial layer 13a. The entire part is then subjected to the heating treatment to vitrify the layer 13a and to form the transparent glass film. The stress relieving part is easily formed in this way and the productivity is improved. An equally good alternative is to impose a shielding material or mask having a prescribed shape on the substrate and to spray the fine glass particles thereon.

Title: Semiconductor laser driving device
Inventor: KAWASHIMA SEIICHIROU
IPC: H04B10/50
Filed: 1990-08-20
Abstract: PURPOSE:To simplify and miniaturize a circuit by converting non-return-to-zero(NRZ) code input data into RZ codes by turning on a transistor only when a clock is at a prescribed level and making RZ conversion on a semiconductor laser by modulating the laser with the RZ codes. CONSTITUTION:Only when both input data and a clock respectively supplied to the bases of transistors 4 and 5 are at high levels, the transistors 4 and 5 are conducted to each other and an electric current flows from a current source 6 to a semiconductor laser 1. When the input data or clock is at a low level, on the other hand, no electric current flows from the source 6 to the laser 1, since either one of the transistors 4 and 5 is turned off. Accordingly, the input data are converted into RZ codes in accordance with NRZ code input data and the level of the clock and the laser 1 is driven. Therefore, the circuit can be simplified and miniaturized, since no OR element is required.
