Title: Range-by-range gain-controlled light amplifier, method for controlling gain of light amplifier range-by-range, light receiver, and light repeater
Inventor: YAMAMOTO SHU
IPC: G02F1/35
Filed: 1995-03-08
Abstract: PURPOSE: To reduce noise over a wide range of input signals by controlling the output of an excitation light source so that the light amplification gains of light amplifier units can successively become corresponding gains from the unit of the preceding stage of cascade-connected light amplifier units while that of the light amplifier unit of the succeeding stage is suppressed as the light receiving level becomes lower from a high value. CONSTITUTION: First and second excitation light source drive circuits 22 and 23 are respectively made to generate drive currents so that the light outputs of first and second excitation light sources 11 and 12 can become proportional to an APC(automatic power control) reference current by means of current-voltage conversion circuits 20 and 21. When, for example, the light outputs of the light sources 11 and 12 become higher while the electric power of the signal light inputted to a first output signal level detector 15 is large, an excitation light source control circuit 19 controls the light output of the light source 11 until the output voltage of the detector 15 becomes about -0.75V. When the output voltage of the detector 15 becomes <=-0.75V, the light output of the light source 12 starts to increase.

Title: Microcomputer
Inventor: KANAYAMA HIDEYO
IPC: G06F15/78
Filed: 1986-03-05
Abstract: PURPOSE:To suppress a non-maskable interrupting request until a prescribed processing execution is completed even when a non-maskable interrupting request signal is inputted immediately after resetting by providing plural interrupting control circuits and a means to suppress the output. CONSTITUTION:When a resetting signal is inputted to an interrupting control circuit 3, an FF 23 and an FF 24 are reset and an output Q comes to be a logic 0. Thus, the output of a non-maskable interrupting control circuit 21 and a maskable interrupting control circuit 22 is prohibited by AND gates 25 and 26. Even when a non-maskable interrupting request signal NMI is inputted immediately after the system resetting is executed by a resetting input signal, the non-maskable interrupting request can be prohibited until a signal EI to set the FF 23 and the FF 24 comes to be a logic 1. Consequently, after the processing to initialize a CPU is executed, by making a signal EI into the logic 1 from the CPU by the instruction, the original processing can be executed without fail without causing the run-away of the CPU at the time of return from an interrupting processing.

Abstract: PURPOSE: To attain safety use of gas, by disposing an electromagnetic valve for opening and closing a gas supply passage at a suitable place, for instance, on the outside of the house, so that gas may not be supplied to the gas supply line inside the house when gas is not used.  
     CONSTITUTION: On the upstream side of gas supplying passage 1, preferably, at a suitable place on the outside of the house, there is disposed an electromagnetic valve 4 for opening and closing the gas supplying passage 1. In using a gas appliance 2, manual switches S2, S3 are at first closed, whereupon a relay coil 12 is energized and current is supplied to the electromagnetic valve 4 via a relay switch S4, so that the gas supplying passage 1 can be opened. When an appliance cock 3 is opened after the electromagnetic valve 4 is opened, the gas appliance 2 can be used in the same way as in the conventional arrangements. In this state, if the cock switch S1 is opened, the gas supplying passage 1 can be kept open since the relay coil 12 continues to be energized via a by-pass circuit C3 and a manual switch S3.

IPC: A63F7/02
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a shooting device for pachinko machine which can strike pachinko balls at desired positions while their flying directions are stabilized. SOLUTION: In this shooting device, an assumed line L is set as tying the center of the shaft 50 of a ball striking rod 27 furnished with a tip 13 to the point of collision with a detent ball, and the shaft 50 is positioned where the tangent drawn by the rod tip 13 in the position of the line L at the time of rod tip collision with the detent ball is parallel with the contacting plane (s) or intersecting nearer the other end of a ball discharge band 16 than the contacting point in collision. Because the direction of an impact force given to the detent ball by the rod tip 13 becomes parallel with the contacting plane (s) or intersecting the other end part, the ball flying direction is stabilized, and loss of the kinetic energy given to the detent ball from the impact force can be suppressed, so that it is possible to stably strike the balls at the specified positions on the game board.
