Title: Solid-state image pickup device
Inventor: AKIYAMA TOSHIYUKI
IPC: H04N5/335
Filed: 1981-10-14
Abstract: PURPOSE:To pick up excessive charges without provision of a gate voltage control line and an excessive charge pickup line newly, by elaborating a plan for the connection of output terminals and control terminals of an excessive charge pickup switch. CONSTITUTION:Excessive charge pickup MOSFETs 151-15n are connected to a light emitting diode 1, a gate voltage of the FET15i is controlled with a DC video voltage applied to a horizontal output line 10, and an excessive charge is picked up through a line connected to the gate of a vertical switch MOSFET9i. Thus, the excessive charge produced in a diode can be picked up through the FET15i having lower wall height than that of an FET9i. The excessive charge passing through the FET15i can be picked up through a line 20 connected to the gate of the FET9i. This excessive charge can not give any adverse effect on a vertical shift register 3.

Filed: 1992-06-22
Abstract: PURPOSE:To speed up character generation even when output devices are alternated by developing characters to be printed in a free time in character display operation or in parallel and registering them in a cache memory for printing.

Title: Method for separating aluminum foil and lamination paper
Inventor: MIYAZAKI TAKAYUKI
IPC: B09B5/00
Filed: 1997-06-04
Abstract: PROBLEM TO BE SOLVED: To provide a method for separating an aluminum foil and a lamination paper without burning cut waste in which an aluminum foil and lamination paper are laminated. SOLUTION: A cut waste 3 is put into a hammer crusher 6. The waste 3 is formed by laminating an aluminum foil and a lamination paper. The hammer crusher 6 is a crusher utilizing mainly impact forces. As a result, the aluminum foils is made round into an aluminum grain. On the other hand, the lamination paper is loosened into a cotton-like body. Under atmospheric conditions, aluminum grains tend to fall down, but the cotton-like body is hard to fall down. The difference in the behavior of both of the bodies is utilized to separate them so that aluminum grains can be separated without burning them.

Title: Flyback transformer high volatge generation circuit
Inventor: UNO KAORU
IPC: H04N3/18
Filed: 1992-05-29
Abstract: PURPOSE:To prevent heat from being generated when abnormality occurs by detecting the increment of a current when short-circuit occurs between the neighboring coils of a flyback transformer, and stopping a power supplied to the flyback transformer based on a detection signal. CONSTITUTION:When the short-circuit between the neighboring coils of the high voltage coil L2 of the flyback transformer 51 is generated and overcurrent flows on a shunt resistor R1, voltage drop due to the overcurrent occurs at both ends of the shunt resistor R1. Such voltage drop causes to generate bias between the emitter and the base of a first transistor Q1, which turns on the first transistor Q1. When the first transistor Q1 is turned on, a second transistor Q2 is turned on, and as a result, a switching transistor Q10 is turned off, therefore, the excitation current of a relay circuit goes to zero, and a relay contact 58a is opened. Therefore, the operation of a power source circuit 60 is stopped, and the overcurrent flowing in the primary side coil L1 of the flyback transformer 51 due to the short-circuit between the neighboring coils goes to zero.

Filed: 1978-12-22
Abstract: PURPOSE: To prevent the temperature change of pressurized ink, providing with operating piece to move toward two directions, a valve fixed to it, and a fluid hole to be shut with the valve.  
     CONSTITUTION: A solenoid valve connects pipe 34 to the ink jet head 9 and a pipe 35 to the accumulator 8 respectively. Since the operating piece 20 puts a straight line to connect a pin 22 and 25 as a dead point, when the piece crosses this dead point, it is maintained stably under valve opening condition and valve shutting condition by force of a spring 21. Wherein, when the first solenoid 31a 1  or the second solenoid 31a 2  is energized momentarily, the valve is fixed to operating piece 20, the valve 26 passes through the dead point to move toward the direction to shut or open the ink outlet 10d. Subsequently, it is held on the stable position by force of the spring 21. Consequently energizing is carried out momentarily, the solenoid is out of the body, heating due to the solenoid does not affect to ink.

Title: Plasma chamber
Inventor: SHAN HONGCHING
IPC: H01L21/3065
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To attenuate the negative DC bias voltage of the cathode against the anode without application of RF power to the cathode by a method wherein an exhaust baffle, having one or more curved paths or zigzag paths, is provided. SOLUTION: A curved path is partitioned by an annular protruding parts 14 and 16, the protruding part 14 is extending into a manihold cavity 54 from an anode shield 10, and the protruding part 16 is extending into the manihold cavity 54 from a cathode shield 12. As the exhaust path in baffles 14 and 16 is sufficiently long and curved, the density of ions in the exhaust gas in the downstream of the exhaust baffle becomes lower than the level necessary to maintain plasma. The exhaust baffles 14 and 16 block the plasma and it is vanished. Accordingly, the negative DC bias on a cathode 30 can be made small. As a result, the negative DC bias voltage of the cathode can be lowered without application of RF power to the cathode.

Abstract: PURPOSE:To prevent the adhesion of carrier to an electrostatic latent image carrier by outputting a previously determined developing bias at the time of image formation, and even at the time of generating a trouble, continuously outputting the developing bias of the same voltage value as that of the image formation. CONSTITUTION:The image forming device executes inversional development by means of a two-component developer consisting of toner and carrier and develops an electrostatic latent image carried on the surface of a photosensitive drum 1. At the time of forming an image, the developing bias is impressed from a developing bias power supply 42 to a sleeve 12 of a developing device 5.

At that time, a developing bias power supply 42 is controlled so as to continuously output the developing bias with the same voltage as that of the image formation. Consequently, the adhesion of carrier to the drum 1 can be suppressed and the drum 1 or a cleaning device 8 can be prevented from being damaged.
