Title: Voltage conversion circuit
Inventor: NAGASE MAMORU
IPC: G11C11/409
Filed: 1990-01-31
Abstract: PURPOSE:To charge a bit line at a high speed without deteriorating the sense sensitivity nor the delay of the sense speed by providing a means which holds the output voltage at the level of the power voltage applied externally in a stand-by state of an internal circuit and then securing a self-active state synchro nously with the time when the internal circuit is activated. CONSTITUTION:In a stand-by state of an internal circuit, the output voltage VINT of the internal circuit is held at the level of the power voltage VEXT applied from outside by a means T7. This means T7 also secures a self-active state synchronously with the time when the internal circuit is activated. In such a constitution, it is possible to reduce the influence of the level-down of the output voltage due to the connection of an internal circuit to be driven secured to an output part. Thus a bit line can be charged at a high speed without deteriorating the sense sensitivity nor the delay of the sense speed.

Title: Engine valve driving system
Inventor: OZEKI KEIJI
IPC: F02D9/06
Filed: 1995-02-10
Abstract: PURPOSE: To prevent pressure governing lift by sealing operation oil in an oil chamber by means of a check mechanism in the case that a rocker arm is not operated against an exhaust valve, and suppressing sliding a piston member integrated with the exhaust valve. CONSTITUTION: Operating oil whose pressure is increased to be a specified value is supplied into an oil chamber 11 by means of a hydraulic supply means. External force is applied from a portion excepting a rocker arm 7 so as to drive an exhaust valve 5 in an opening direction, which is failed since the exhaust valve 5 is not lifted. When the rocker arm 7 is not operated, namely, the oil chamber 11 is a sealed condition by means of a check mechanism 12. A piston member fixed to a valve stem 5A and driven unitedly with the exhaust valve 5 is not slid inside a recession 9 due to non-compressability of the operation oil, so that the exhaust valve 5 is not driven to open. Pressure governing lift due to exhaust gas pressure from an exhaust port is prevented without strengthening a valve spring 6.

CONSTITUTION:Both an input D and an output Q are set to '1' or '0', then an output and a NOT output of an exclusive OR element 100 are respectively at '0' and '1', and NOT switch elements 110,120 reach a high impedance state. When a clock phi is at '1' or '0', the NOT twitch element 111 or 121 is conductive, but since the switch element 110 or 120 is in a high impedance state, a level at the output Q is kept. When the level of the input D differs from that of the output Q, the output and the NOT output of the element 100 go to '1' and '0', the elements 110,111 are conductive when the clock phi is at '1' and the level of the input D is equal to the level of the output Q. Similarly the elements 120,121 are conductive when the clock phi is at '0' and the level of the input D is equal to the level of the output Q.

Abstract: PURPOSE:To obtain the images of good gradation characteristic by using the specific screen-form photoreceptor in the method of forming the images by modulating ion current by the first latent image formed on the screen-form photoreceptor. CONSTITUTION:The screen-form photoreceptor 15 comprising providing a photoconductive layer 17 and surface insulation layer 18 on the modulating corona source side and the opposite side and a potential maintaining layer 19 on the modulating corona source side is used for a conductive member 16.

Next, the secondary voltage application of the polarity opposite from the above is done by a corona discharger 27 to make the surface potential of the insulation layer 19 largely negative. Next, exposure is done from the arrow 30 direction through the original image 29 to form the primary  latent image on the photoreceptor 15, thence negative polarity corona ions are radiated from a  modulating corona wire 32 and while the specified negative charging is being applied to the potential maintaining layer 19, the ion current is modulated by the primary latent image of the  photoreceptor 15 to form the secondary latent image on the chargeable surface 31. This is then  developed with positive-charged toner.
