    摘要: In a phase-modulated fiber-optic gyroscope having as essential components a fiber-optic cable having a sensor coil portion and a portion provided with a phase modulation device, a light-emitting device that issues coherent light, a beam splitter by which the light issuing from the light-emitting device either directly or via an optical fiber is split into two beams which are launched at opposite ends of the fiber-optic cable, a light-receiving device into which the light beams that have been transmitted through the fiber-optic cable and that emerge from opposite ends thereof are launched after they are re-combined by the beam splitter, and a synchronous detector circuit that receives the output of the light-receiving device and that detects a phase-modulated frequency component, the improvement wherein the gyroscope further includes a DC component detector that receives the output of the light-receiving device and that detects the DC component of the output, a reflected light quantity setting unit that presets the level of the reflected light H in the DC component which was reflected by the edge faces of lenses, optical fiber and other parts of the optical system and which did not pass through the sensor coil, a reflected light quantity subtracting unit that subtracts the present level of reflected light H from the output D of the DC component detector, and a division performing unit that divides the output of the synchronous detector by the output R of the reflected light quantity subtracting unit and that outputs the result of the division.

    摘要: There is disclosed a dusttight storage cabinet apparatus used for storing works such as wafer cassettes for containing semiconductor wafers. The storage cabinet apparatus includes: a housing having an entrance, formed in its front wall, for allowing works to come in and go out of the housing therethrough; an air supply duct for supplying the inside of the housing with clean air; a vertical rotation shaft rotatably disposed in the housing for turning about its longitudinal axis; a drive motor for turning the rotation shaft; and a rack assembly of a substantially cylindrical structure. The rack assembly is coaxially secured to the rotation shaft and has a plurality of compartments for storing the works therewithin. The compartments open radially outward and are partitioned off from one another so as to prevent cross contamination by dust among the compartments.

    摘要: A distribution type fuel injection apparatus has a fuel injection pump having a solenoid valve for controlling pressure of a high-pressure chamber of the apparatus. The solenoid valve is actuated or deactuated at the optimum time for fuel injection end or beginning by a control signal produced by a circuit for computing the optimum timing in accordance with the condition of engine operation. Thus, precise control of injection timing or injection amount injected can be attained by electronic control without a complex mechanical structure.

    摘要: A television receiver including: a reception control unit which judges whether reception of the cable television broadcast signal has succeeded, by setting the channel data composed of the combination of the frequency table stored in the first storage unit and the modulation method stored in the second storage unit, the modulation method corresponding to the tuned channel. The reception control unit sequentially changes the channel data to be set in a previously determined order to make the reception unit receive the cable television broadcast signal corresponding to the tuned channel when the reception control unit judges that the reception of the cable television broadcast signal has not succeeded.
