Title: Control method at speed change for internal combustion engine of motorbicycle
Inventor: KANEMURA SHINJI
IPC: F02D29/00
Filed: 1989-08-25
Abstract: PURPOSE:To improve speed change feeling at speed change of a constant-mesh transmission by constituting a device so as to temporarily bring down engine output, according to the detected value of opening and varied quantity of opening of the throttle valve of an internal combustion engine. CONSTITUTION:When a change pedal switch 12 is ON, namely, speed change is performed in a transmission 13 and a throttle valve opening thetaTH is larger than a prescribed value thetaO (a throttle valve opening discriminating value to discriminate the tendency of generation of speed change shock due to gear change), ECU 5 computes a throttle valve varied quantity DELTAthetaTH/DELTAt, and at DELTAthetaTH/DELTAt > X it is discriminated that the speed change shock is large. In this case, according to the varied quantity DELTAthetaTH/DELTAt, correcting value of ignition timing is instituted large. Hereby, according to the throttle valve opening varied quantity DELTAthetaTH/DELTAt, delay angle from an optimum ignition timing becomes large, and decreasing degree of engine output becomes also large. Therefore, gear change is performed without resistance and speed change shock is softened.

Title: Focused ion beam device
Inventor: SAWARAGI HIROSHI
IPC: H01J37/147
Filed: 1988-08-31
Abstract: PURPOSE:To eliminate tailing of ion beams by composing with an upper stage and a lower stage deflecting electrodes, and retarding the application of the blanking voltage to the lower stage deflecting electrode from that to the upper stage deflecting electrode. CONSTITUTION:The signal from a blanking signal generator 16 is amplified and applied to a blanking electrode 12 at the upper stage, and ion beams are blanked. In this case, since the ion beams are fed to a blanking electrode 13 delaying a specific time through a delay circuit 18, the signal is not fed to the electrode 13 when it is fed to the electrode 12. As a result, the beams passing through the electrode 12 advance straightly without being deflected by the electrode 13. And when the beams deflected by the electrode 12 reach the electrode 13, the beams are deflected further. Consequently, no tailing of the ion beams is generated on the target.

Then, impedance is matched and effect by an external circuit can be adjusted.

Filed: 1993-08-11
Abstract: PURPOSE:To improve the power supply efficiency by preventing simultaneous turning-on of both a main switch and a synchronous rectifying MOSFET in a switching power supply employing the MOSFET for synchronous rectification. CONSTITUTION:Three resistors 4 to 6 between a reference voltage source 3 and the ground are connected in series, and reference voltages V1 and V2 for comparators 7 and 8 are created. These reference voltages V1 and V2 are compared with a chopping wave v3 by the comparators 7 and 8, and a main switch 1 and a MOSFET 2 are respectively ON/OFF-controlled depending on respective comparative outputs v4 and v5. By doing this, V2 is always lower than V1 so that the pulse width of a drive pulse v6 of the MOSFET 2 always becomes smaller than that of the main switch 1 so that both the switches will never turn on simultaneously.
