Title: Optical path shift driver
Inventor: ISHII SATOSHI
IPC: H04N5/351
Filed: 1991-03-29
Abstract: PURPOSE:To improve accuracy for shifting an optical path by accurately controlling the rotational angle of an optical path changing member. CONSTITUTION:A signal SSE from an angle sensor 12 (photointerrupter) is amplified by an amplifier 11a and supplied to a voltage comparator 11b. The signal SSE is the signal SSE corresponding to the rotational angle of a glass plate (optical path changing member). When the glass plate is set at first and second rotating positions, reference voltages supplied from a voltage generator 11c to the voltage comparator 11b are respectively defined as V1 and V2. When the signals are defined as SSE1 and SSE2 in the case of setting the glass plate at the first and second rotating positions, the V1 is alphaSSE1 and the V2 is alphaSSE2 (alpha is the amplification factor of the amplifier 11 a). A comparison error signal from the voltage comparator 11b is supplied to a driver 11e and the glass plate of an optical path shifter 10 is rotationally driven. Since negative feedback control is executed so that the output of the amplifier 11a can be equal to the reference voltage, the rotational angle of the glass plate can be accurately controlled only by switching the reference voltage.

Title: Starting circuit for high frequency inverter
Inventor: OKANO KEISHI
IPC: H02M7/515
Filed: 1981-04-30
Abstract: PURPOSE:To stabilize the start of a high frequency inverter in response to a load by enabling to adjust the capacity of a starting capacitor in response to the load by controlling the firing of a starting thyristor, thereby generating a necessary commutation voltage. CONSTITUTION:A capacitor 5X is charged through a diode 8 before starting. A starting thyristor 6X is fired at the starting time to discharge the charged charge to a load 4X, thereby generating a commutation voltage, and a power inverter thyristor 3 is thus commutated for starting. Thereafter, the commutation of the thyristor 3 is continued with the load voltage generated by the energy from the side of a power converter thyristor 1, thereby continuing the inverter operation. When the load amount is varied, i.e., when a load switching contactor 12Y is thrown, a starting thyristor 6Y corresponding thereto is fired, the charged voltage of a starting capacitor 5Y is discharged at the load side, thereby adjusting the discharging amount of the starting capacitor responsive to the load amount.

Inventor: ISAKA SHINICHI
IPC: F02B39/04
Filed: 1986-03-27
Abstract: PURPOSE:To improve the suction efficiency, by a method wherein driving of a displacement type compressor forming a supercharger is tuned with the number of revolutions of an engine through a timing regulating mechanism, and the pulsating flows of the driving and the number of revolutions are tuned to offset each other. CONSTITUTION:A supercharger is formed with a displacement type compressor 4, feeding air from an intake air port 1 through an intake air passage 2 to an engine 3.

Title: Multiple interruption control system
IPC: G06F9/46
Filed: 1992-03-25
Abstract: PURPOSE:To effectively use an interruption/port terminal and to contribute to the effective use of a general-purpose port terminal in a multiple interruption control system using a single chip type microcomputer. CONSTITUTION:An encoder 2 encodes the interruption factor signals 11-25 into a binary codes and supplies these codes to the interruption/port terminals 40-43. The same vector value is secured to all vector values corresponding to the terminals 40-43. Thus a microcomputer 1 decides the type of each interruption factor based on the states of the terminals 40-43 when an interruption is inputted and carries out the processing in response to each interruption factor. Therefore a general-purpose port terminal can be effectively applied to other purposes.

For example, when the above- mentioned signal from the CNT 10 is obtained as first arrival, in order to send a deciding output A with the first arrival for the above-mentioned signal from the CNT 10, REGs 13 and 14 are activated by respective FADs 20 and 50. Then, in correspondence to the contents of an REG 12, the CNT 10 sends an address and the data to the REG 13 and a writing instructing signal is sent to the REG 14. Then, the same data are written to the respective same addresses of the MMs 16 and 56. Thus, the memory contents of the respective devices are coincident with each other.
