At this time a capacitor 20 charged through a diode 21 in response to the voltage of the power source is added, the base of the transistor 18 is controlled by the voltage, thereby suppressing the variation in the drooping starting point of the output current vs. voltage characteristics by the variation in the voltage of the power source. Therefore, the overcurrent can be detected by a simple circuit accurately and safely.

Title: Rare gas ion laser tube
Inventor: KASAMATSU MITSUO
IPC: H01S3/032
Filed: 1980-02-20
Abstract: PURPOSE:To minimize the pulverization of graphite and prolong the life of a laser tube by coating the inner surface of the charging center hole in the graphite plate constituting a plasma thin tube with silicon carbide. CONSTITUTION:The graphite plate for the plasma thin tube of a laser tube is made of graphite and the inner surface of its charging small hole 8 is coated with silicon carbide 12. When the graphite plate of said structure is employed as a plasma thin tube in a rare gas ion laser tube, charging is performed through the center small hole 8, and the temperature of the whole plate rises. However, because the inner surface of the hole 8 is coated with silicon carbide 12, pulverization is restricted to the minimum. Moreover, the heat dissipation from the plate is mainly performed by the peripheral surface. however, there is no silicon carbide on said portion, where graphite itself is exposed. Therefore, there is no interference with the heat dissipation.

IPC: F02D41/36
Filed: 1982-02-10
Abstract: PURPOSE:To keep the fuel distribution of each  cylinder uniform by controlling an injection valve so that the fuel injection is not started until a suction valve is closed when no blow-back from the suction valve occurs in cylinders jointly using a common suction manifold. CONSTITUTION:The start and end of injection of a fuel injection valve 1 is set and controlled by the control signal from a control unit 5. According to the injection timing of a four-cylinder engine, the ignition signals of No. 1 and No. 2 cylinders are frequency converted and are used as trigger signals. A computer calculates a delay of A+B consisting of a delay B from the time a trigger signal is issued to the ignition time and a delay A until the suction valve is closed, and feeds a control signal directing the injection time to the injection valve 1. If the suction valve closing angle is 60 deg. ATDC, the ignition timing at a low engine speed region where particularly much blow-back occurs is about 30 deg. BTDC at maximum, thereby the injection timing of No. 3 cylinder in relation to No. 1 cylinder is preferably set at about 90 deg. after the ignition signal has occurred.

Abstract: PURPOSE:To decrease the processing time of a microprogram, by providing a first-in/first-out memory to store the head part of the transmission information including the control information into the said first-in/first-out memory and performing an input/output control process in parallel to the input/output operation of data. CONSTITUTION:The transmission information including the control information supplied from an external circuit 2 at the head part is stored in a first-in/first- out memory 11 as well as in a storage circuit 12. the memaory 11 is large enough to store the control information contained at eh head part. When the memory 11 is filled up, this information is informed to a microprogram control circuit 14. The circuit 14 fetches the control information out of the memory 11 and starts decoding . In this case, the circuit 12 is under its storing action and the circuit 14 performs an input/output control process independently of the data input to decide the necessity of the data to be supplied to the circuit 12. Thus the input of data is discontinued. the circuit 14 can perform a process of data as soon as it knows the end of the input of data. As a result, the processing time can be decreased for a microprogram.

Title: Balance adjusting system for branching circuit network
Inventor: MURASAWA KENICHI
IPC: H04B1/58
Filed: 1978-02-25
Abstract: PURPOSE:To secure an easy balance adjustment of the branching circuit by means  of the single measurement instrument. CONSTITUTION:The reference signal of the reference pulse duration sent from measurement instrument ME2 of remote side unit SR2 is received via self-unit SR1 and reception terminal RD, and then the auxiliary signal featuring the different pulse duration to the reference signal is transmitted through SR1. The transmission and reception of these signals is performed via the branching circuit network provided at the line side of unit SR1 and SR2. Measurement instrument ME1 decides the balance condition of the branching circuit network based on the timing relation between these signals, and at the same time the lamp glows or blinks. Accordingly, in case the lamp blinks because of the defective balance condition, the variable impedance of the branching circuit network is adjusted until the lamp glowing is maintained. Thus, the optimum balance condition is obtained.
