Title: Diode gate circuit
Inventor: TASHIRO ISAO
IPC: H03K17/74
Filed: 1978-05-12
Abstract: PURPOSE:To reduce the leak of the error current by controlling the constant current source by the output of the detector for the unbalanced current. CONSTITUTION:When the driving pulse is applied to current switching type switch circuit 3 and 4 with transistor 5 and 7 made to conduct, the current flows to diodes 10-13 via constant current source 1 and 2. And diode bridge 9 openes to secure the conducting state between input terminal 14 and output terminal 15. Then transistor 6 and 8 are made to conduct by the driving pulse, and thus diodes 10-13 are biased reversely via resistance 16 and 17. As a result, no current flows to bridge 9 with the nonconducting state secured between terminal 14 and 15. During such operation, the error current is caused if source 1 and 2 are under an unbalanced state to be leaked outside through terminal 14 and 15. To prevent this, the error current is integrated by error current detector 18 comprising differential amplifier 19 and capacitor 20 to be converted into the voltage level which is supplied to variable constant current source 2.

Title: Opening and closing timing controlling method for intake and exhaust valves of engine
Inventor: OKUNO TATSUJIRO
IPC: F02B1/04
Filed: 1985-03-20
Abstract: PURPOSE:To unify distribution of EGR ratio to cylinders in a four-cylinder engine by quickening the ignition timing of the intake valve of a taster-ignition cylinder rather than that of the intake valve of the next-ignition cylinder so as to shorten an overlap period of both an intake valve and an exhaust valve if two of the cylinders are adjacent and ignitions are performed sequentially. CONSTITUTION:In couples of adjacent first and second cylinders #1 and #2, and adjacent fourth and third cylinders #4 and #3 wherein ignitions are performed sequentially, the closing timings of the intake valves of respective cylinders #2 and #3 which have faster-ignition timings are made quicker than the conventional timings. Thus said intake valves may has rarely an overlap period with respect to the ignition timings of the intake valves of the cylinders #1 and #4 in which ignitions are to be performed later. If gas is blown back from the cylinders #1 and #4 to respective intake pipes, the gas will not flow into the cylinders #2 and #3 because intake valves of cylinders #2 and #3 are immediately closed; so that internal EGR can be prevented to occur.
