Filed: 1981-08-20
Abstract: PURPOSE:To prevent the disorder of charge-distributed toner arrangement and the lowering of charge amounts by making the outlet end of a supporter coincide with the end of toner passage side in a multi-needle electrode in which plural needle electrodes are buried in the supporter. CONSTITUTION:A multi-needle electrode 40 has such a shape that the outlet end 200a of a supporter 200 is cut off in such a way as to make the outlet end C(the downstream end of the moving direction of a toner) of the supporter 200 coincide with the end 100a of the toner passage side of a charge-injecting electrode 100. Thus, charge-distributed toner arragement does not come into contact with the outlet end 220a of the supporter 200 through the electrode 100, and thereby the disorder of the toner arrangment and the lowering of charge amounts injected by frictional charging can be prevented. Furthermore, by biasing the outlet end C of the supporter 200 from the center of the electrode 100, an allowable range of the contacting angle theta of the electrode 100 on the periphery of a toner roller 1 can be widened.

Abstract: PURPOSE:To increase the operating speed of a memory cell circuit by providing the title circuit with a circuit for forcedly pulling up a digit line in a pull-up element only at the end of writing. CONSTITUTION:When it is defined that the threshold voltage of a depression type FET is VT[V] (VT/0) and a current leading voltage in the forward direction of a diode is Vf[V], F102, D100 and D101 are turned to high impedance when digit line potential VDL is based on the shown inequality I (VWE; low level selection write enable line level). In case of ending writing operation, a high level selection write enable signal line WE is turned to a low level and a low level selection write enable signal line WE is turned to a high level. At that time, the condition of the inequality I is not satisfied and the F102 and D101 are turned on. Thereby, the digit line DL is pulled up also by the F102 and D101 up to potential forming the relation of VDL = VDD (high potential power supply) - VT - Vf. Consequently, a digit line recovery time can be shortened.

Title: Image recorder
Inventor: MATSUMOTO TATSUSHIGE
IPC: G03G15/16
Filed: 1984-06-28
Abstract: PURPOSE:To reduce the size of an image recorder by providing image exposing means which expose an image to a photoconductive layer from the inside of a photosensitive drum, erasing the electric charge according to the image, make the electrostatic sticking strength of a toner smaller than the transfer force of the toner and transferring the toner to a recording medium. CONSTITUTION:The photoconductive layer 14 of the photosensitive drum 11 is made conductive in the part irradiated with light and grounds and discharges the charge held on the outside peripheral surface through a transparent electrode 13. The phenomenon is generated by image exposure and the charge on the outside peripheral surface of the layer 14 is erased by the exposed image. The sticking strength of the toner layer 18 to the drum 11 decreases in the part of the layer 18 on the outside peripheral surface of the drum 11 where the charge is erased. The decrease in the sticking strength of the layer 18 to the drum 11 corresponds to the exposed image when the charge is erased by the image exposure. The toner layer 18 is transferred to recording paper 7 adcording to the exposed image when the decreased sticking strength is smaller than the transfer force by the charge for transfer. The need for a cleaning part for removing the toner remaining on the photosensitive drum is thus eliminated and the size of the device is made smaller.

Abstract: PURPOSE:To make it possbile to prevent high pressure air from leaking toward lower course side of a suction tube by installing a supply valve closing electrode switch for turning in the pump direction at a level higher that of a supply valve closing electrode switch for turning in impeller direction. CONSTITUTION:High pressure air supply valve closing electrode switches 11e and 11a for detecting the water level inside a suction tube 5 are vertically arranged on a water level detecting tank 10 provided in communication and inparallel to the suction tube 5. Hereat, the electrode switch 11e positioned upward and the electrode switch 11g positioned downward are arranged to operate when a runner 4 races in the pump direction and in the impeller direction respectively. Thus, it is possible to main a distance from the rocking water surface to the upper end of the horizontal part of the suction tube 5 can be maintained longer in the case of turning in the pump direction than that in the case of turning in the impeller direction because the water level in the suction tube 5 is maintained at a level higher in turning in the pump direction than that in turning in the impeller direction. Accordingly, high pressure air which is discharged like a jet from control pipings 6, 7 can be reduced in its amount for leaking toward lower course side of the suction tube 5.
