Abstract: PURPOSE:To prevent the generation of rush current at the throw-in of a power supply by detecting the rise of power supply voltage and keeping a chip at nonselecting state until the voltage reaches a prescribed voltage. CONSTITUTION:At the throw-in of the power supply, the output of an inverter circuit consisting of FETs Q3, Q4 is kept at a high level until the divided voltage of the power supply voltage by a voltage dividing circuit constituted of FETs Q1, Q2. Therefore, a voltage detecting output B by two pairs of serial inverters Q5, Q6 and Q7, Q8 is raised similarly to the power supply voltage Vcc and is kept at the high level until the voltage Vcc reaches a fixed stable voltage. Consequently, an FET Q11 connected in parallel to an FET Q10 forming an internal timing generator together with a precharging FET Q9 is turned on, and even if a chip selecting signal unti-CS is in a low level, an internal timing signal CS is turned to the low level and the chip is turned to the nonselecting state. Thus, an address buffer circuit, an address decoder circuit, etc. on the chip are not turned to the operating state, so that the generation of lash current is prevented.

Title: Variable flywheel controlling mechanism
Inventor: INOUE KAZUO
IPC: F16F15/31
Filed: 1987-07-03
Abstract: PURPOSE:To absorb an impact at the time of clutch actuation by holding it in a half-engaged state till both rotational frequencies of an engine and an auxiliary flywheel becomes almost equalized at a low engine speed range. CONSTITUTION:When it is so judged that an engine is in a high speed range by a hydraulic control device 3, a spool valve 16 is turned to ON and an oil feed passage 13 is opened, thereby releasing the engagement of a clutch device 6. At this time, since all will not act but a fixed flywheel 5, accelerating performance is improved. At the time of a low engine speed range, if the spool valve 16 is turned to OFF, the passage 13 is closed, and an oil return passage 15 is opened instead. At this time, if it is so discriminated that rotational frequency of the engine is larger than that of the auxiliary flywheel 7, the passage 15 is closed by a valve 17. In consequence, a piston 9 keeps an intermediate position by dint of hydraulic pressure in residual oil, and a clutch 6 keeps its half- engaged state. Both rotational frequencies of the auxiliary flywheel 7 and the engine becomes equalized, the valve 17 opens the passage 15 so that both flywheels 5, 7 are engaged with each other but the impact is remarkably reduced.

Abstract: PURPOSE:To enable a change-over of one set of laser device to a punch welder under a simple signal control and to reduce a cost of the solid laser oscilator device by applying high voltage-proof parts only in a part of the circuit. CONSTITUTION:Capacitance C1 is charged to a voltage V1 by DC power source 1, SCR31 is turned on to charge C2 through a winding L1. When a relation of C1>>C2 is found, V2 2V1 may be made. SCR31 is automatically turned off. SCR34 is turned on, the lamp 3 is illuminated to energize the laser 4. Laser oscilation is produced by C2, L2, and lamp 3. Proper selection of C2 and L2 may enable a welding operation. When SCR32 is turned on after C2 is charged to V2, C3 is charged to V3 through L2, and when a relation of C3<<C2 is found, V3 2V2 may be obtained. When the lamp 3 is discharged through L3 after C3 is charged, a laser oscilation having a short duration time and a high peak value can be performed, then a punching work can be made. After SCR35 is turned on and a voltage of C2 is reduced to nearly zero, then C2 and C3 are charged again. With this arrangement, several kinds of laser workings can be performed.
