Abstract: PURPOSE:To obtain a high cleaning property without injuring the surface of an image supporting material and prevent filming or the like of a toner on the image supporting material, by using electrical force to move the toner stuck to the surface of the image supporting material effectively in case that the image supporting material of the dry electronic copying machine, where a visible image is formed by the dry development and is transferred to obtain a final copy, is cleaned. CONSTITUTION:A photosensitive drum 1 after transfer is rotated to a cleaning part with an untransfer toner stuck and is cleaned. A gap of 1.5mm. is held between a roller 81 and the photosensitive drum 1; and when an alternating electric field to which a DC voltage is superposed is applied while erasing corona ions on the photosensitive drum by an LED array 82 in the roller 81, the toner on the photosensitive drum 1 is moved to the roller 81 and is stuck there. The toner moved onto the circumferential face of the roller 81 is scraped by a blade 83 and is drawn back to a recovering box 84. The toner remaining of the photosensitive drum after separation of a transfer paper is moved to a cleaning part 8 completely.

Patent JP-H0414262-A (JP)
Title: Semiconductor device and its manufacture
Inventor: MAKINO TAKAMI
IPC: H01L29/78
Filed: 1990-05-07
Abstract: PURPOSE:To prevent the build-up of minority carrier, and restrain the generation of kink or the decrease of breakdown strength, by arranging a second opposite conductivity type diffusion layer formed more narrowly than a first opposite conductivity type diffusion layer between a conductivity type semiconductor film and a metal semiconductor compound layer. CONSTITUTION:As the result of impact ionization, positive holes as minority carrier are generated in the vicinity of a diffusion layer 4 turning to a drain, and moved to a floating region existing under a channel forming region by the effects of electric field drift and diffusion. Since the width of an N<+> type diffusion layer 6 turning to a source is formed to be narrow, the PN junction surface between a diffusion layer 6 and a silicon layer 1c is adjacent to a metal silicide layer 5. Hence the positive holes turning to minority carrier flow easily into the metal silicide layer 5 as the leak current. Since the silicide layer does not exist in the diffusion layer 4 turning to a drain, the PN junction surface is not adjacent to a highly conductive layer, and the drain side leak current does not increase. Thereby the minority carrier is reduced, and the deterioration of breakdown strength caused by kink and lateral type parasitic bipolar transistor effect is decreased.

Title: Piezoelectric vibrator element
Inventor: KAWAURA KUNINORI
IPC: H03B5/32
Filed: 1988-05-13
Abstract: PURPOSE:To eliminate the spurious radiation being a cause to frequency jump by specifying the ratio of the length and the thickness of the piezoelectric substance cut from a lithium tantalate single crystal board. CONSTITUTION:Drive electrodes 13, 14 are formed to the opposed major faces of the piezoelectric substance 12 cut off from the lithium tantalate single X crystal board in the piezoelectric vibrator element 11 whose oscillated frequency is 16MHz or over. The relation of length L/thickness H of the piezoelectric substance 12 whose flat shape is square is selected as 12-20, and since there is no possibility of frequency jump due to a voltage change where a spurious Sp is nearly eliminated in the admittance frequency characteristic taking the longitudinal axis as the amplitude and the lateral axis as the frequency, the frequency is changed continuously by the voltage adjustment in the voltage controlled oscillator using the piezoelectric vibrator element 11. The ratio L/H of the length L and the thickness H of the piezoelectric substance of the piezoelectric vibration element is selected to be 12-20 in this way, then the spurious radiation having a frequency higher than the oscillated frequency is eliminated and the characteristic of the oscillator is made stably in case of employing the piezoelectric vibrator for the voltage controlled oscillator.

Abstract: PURPOSE:To shorten the response waiting time on a call outgoing side by displaying the number of distributed incoming calls to the other group, as well when the number of distributed incoming calls to a certain group exceeds the number of responding persons in the group. CONSTITUTION:When the incoming calls to central office trunks(COT) 31-3n are the distributed incoming calls to a group A, a CPU 5 counts up the unresponded accumulated calls out of these calls and stores the number of the calls to an accumulated call counting memory (MB) 62. Next, the counted value of the MA 61 and the overflow memory value set to the distributed incoming call overflow memory (MB) 62 of the group A are read by the CPU 5 and compared. At this time, in the case of the value of the MA 61> the value of the MB 62, the CPU 5 displays the number of the unresponded calls through a channel network(NW) 5 on the D2a of the group A and this number is displayed on the D2b of a group B, as well. Accordingly, the T1b of the group B can alternatively respond the accumulated all of the group A. Thus, the response waiting time on the call outgoing side is shortened.
