Title: Output control circuit of intergrated circuit device
Inventor: IWAKI MASAHIRO
IPC: G06F13/42
Filed: 1982-10-06
Abstract: PURPOSE:To inhibit the switching of a system clock while a driving signal for external device is generated and to obtain an equal signal frequency, by providing a means to keep the frequency of the system clock constant in level regardless of a change of processing state. CONSTITUTION:A means is provided to keep the frequency of a system clock at a constant level regardless of a change of processing state. For instance, when a buzzer ON/OFF signal BO is turned on, the output of an OR gate 13 is set at logic level ''1'' to open and close AND gates 8 and 9. Then the source oscillation is always supplied to a system clock SC regardless of the signal given from an arithmetic control circuit part 14. When the signal BO is turned off, the gate 8 is opened when the control signal sent from the part 14 is set at logic level ''1''. While the gate 9 is opened with the logic level ''0''. Then a clock obtained by giving 1/2 division to the source oscillation is supplied via a frequency dividing circuit 11 when the control signal and the source oscillation are set at high and low levels respectively.

Title: Hydraulic apparatus
Inventor: DOWAITO BURUUSU SUCHIIBUNSON
IPC: F16K31/52
Filed: 1981-11-02
Abstract: A hydraulic system includes a selective control valve and a cam member movable to selected positions for controlling a hydraulic cylinder powered by a pump. A follower is urged to a locking relationship with the cam by a hydromechanical mechanism to releasably hold the control valve in the selected positions. The hydromechanical mechanism includes a bore exposed to sump pressure and to pressure upstream and downstream from a metering valve in a passage interconnecting the pump and the control valve. A hollow apertured sleeve is movably mounted in the bore. An apertured piston is slidably received by the sleeve. A rod, engageable with the follower, extends through the piston and sleeve apertures. A first spring interconnects the rod and the piston and a second spring interconnects the piston and the sleeve. The sleeve moves to a preload position in response to a no-flow differential pressure between the sump and the passage to urge the follower via the rod towards its locking position. The piston moves in response to fluid flow through the passage to bias the follower toward its locking position. The piston and the rod move to automatically allow the follower to release from the cam when the function of the hydraulic cylinder is completed. Also, the sleeve and rod move to automatically allow the follower to release from the cam when system pressure in the passage is lost.
