Title: Cleaning of ion processor
Inventor: KOSHIISHI AKIRA
IPC: H01J37/30
Filed: 1990-01-12
Abstract: PURPOSE:To easily clean a contaminated part in a short period of time by introducing a predetermined gas for cleaning, by generating plasma through the electron irradiation to the gas, and by actuating the plasma for cleaning. CONSTITUTION:A gas for cleaning is supplied in an ion generating chamber 20 of an ion source 2, and electron is irradiated to the gas for cleaning, into a plasma state. The gas for cleaning is further supplied, so as to maintain the pressure in a vacuum container 1 to a certain level, and the voltage sufficient enough to cause glow discharge in the vacuum container 1, is applied to ion deriving electrodes 3a, 3b. The plasma is flown out from an ion deriving slit 24 to the outside of the ion source 2, by gas stream due to the exhaust from an exhaust port 4, and comes into contact with the adhesive material adhered to the electrodes 3a, 3b as well as the surroundings thereof. The adhesive material is removed by the etching effect of the plasma. It is no more necessary to once reduce the inside of the container 1 to a normal pressure state, and a contaminated part can thus be cleaned in a short period of time.

Title: Electrophotographic method
Inventor: ENOKI SHIGEKAZU
IPC: G03G9/08
Filed: 1980-01-19
Abstract: PURPOSE:To form a good transferred image on a plain paper, by using a specified one-component type magnetic toner, forming electrically conductive paths via the toner between a photoreceptor and a roller having a rotary sleeve on the outside of fixed magnets, and injecting charge reverse in polarity to an electrostatic latent image to the toner. CONSTITUTION:The one-component type magnetic toner to be used consists of magnetic powder 11 of 0.3-5mum average particle diameter useful as a colorant, too, colorant 13 of 0.5-5mum average particle diameter, and a binder resin. The raw material in which the sum of colorant 13 and powder 11 amounts to 30-70wt% of the total toner wt., and powder 11 amounts to 35-65wt% is mixed, melted, cooled, and pulverized to give a toner having 8-18mum average particle diameter and 1.8-2.2 true specific density. This toner forms conductive paths 14 between developing sleeve 6 having fixed magnets 9, and photoreceptor 2 on drum 1, and becomes positively charged toner T1 against negatively charged electrostatic image on photoreceptor 2, and  electrostatic latent image T2 is formed with rotation of photoreceptor 1 and sleeve 6. The developed toner image T2 is transferred to plain paper S by imparting charge to the reverse side of  paper S. Since magnetic particles 11 are coarse and the charge of toner T1, T2, T3 is not ready to  decay after charging, superior image transfer is carried out.

Filed: 1992-01-16
Abstract: PURPOSE:To make an output level constant even against a sudden change in a low input level by providing a parallel negative feedback circuit to a bias voltage variable transistor(TR) so as to reduce an impedance in parallel with a bias giving resistor. CONSTITUTION:Parallel negative feedback is applied to a bias voltage variable TR with resistors R1, R2 and an operational amplifier 10 and resistors R1, R2 are connected in series between a collector of the TR and ground. The resistance of the resistors R1, R2 is selected sufficiently larger than the resistance of a resistor RO and a voltage at the connecting point is inputted to a noninverting terminal of the operational amplifier 10 and an output of a reflection circuit 9 is inputted to an inverting terminal. Then the output of the operational amplifier 10 is fed to a base of the TR to apply parallel negative feedback. Then the impedance of the TR connecting in parallel with the bias provision resistor RO is reduced and the time constant comprising the resistor RO and a capacitor CO is reduced. When an optical input level is changed suddenly, the bias voltage is quickly changed to make the output level constant.
