Title: Electrostatic charging device for electrostatic printing device
Inventor: MORIYA TOSHIBUMI
IPC: G03G15/00
Filed: 1986-06-06
Abstract: PURPOSE:To uniformly electrify the surface of an electrostatic recording body even when the surface potential of an electrostatic recording body to be charged has large variance by applying bias voltage which have the opposite polarities to two conductive brushes installed at a front and a rear positions in the rotational direction of the electrostatic recording body and charging the surface of the electrostatic recording body electrostatically. CONSTITUTION:The two conductive brushes 6 and 7 which charge the surface of the electrostatic recording body 1 uniformly are installed at the peripheral part of the electrostatic recording body 1. When a DC voltage of 450 V is applied to the conductive brush 6 positioned on the upstream side, the surface potential of the electrostatic recording body 1 which rushes to a 1st conductive brush 6 with the variance of -350-50V becomes 160+ or -10V after passing through he 1st conductive brush 6. When, however a DC voltage of -50V is applied to a 2nd conductive brush 7, the surface potential of the electrostatic recording body 1 after it passes through the 2nd conductive brush 7 becomes 50+ or -5V, so that the charging operation is performed extremely stably as compared with conventional 50V+ or -tens of volt.

Title: Center key structure for rotary electric machine
Inventor: HIRAI TSUYOSHI
IPC: H02K15/00
Filed: 1977-11-02
Abstract: PURPOSE:To eliminate grease outflow and prevent fouling, by lubricating the slide part between the guide and the center key by means of the grease stored in a sump. CONSTITUTION:On the driving side and on the fixed part in the driven side there are provided a guide 1 and a center key 2 respectively, and the center key is constructed of a guide seat 6 and a guide key 7 removably mounted on the guide seat 6.

Title: Interface system
Inventor: KOTEGAWA TOYOYUKI
IPC: G06F13/14
Filed: 1988-05-27
Abstract: PURPOSE:To inhibit the working of the lower rank devices in a disturbed state by permitting the actuation of a transmission/reception circuit of its own device only in case no coincidence is secured between the comparison output signals of other lower rank devices which are supplied to 1st and 2nd input terminals and at the same time the coincidence is secured between the comparator outputs of its own device. CONSTITUTION:In case the device numbers of two lower rank devices 105 and 106 are selected by a host device 104 in the same setting state, an output signal 110 of a comparator 107 is set at a high level at the level 105 since the coincidence is secured between the device selection signal received from the device 104 via a device selection signal line 101 and the output of a device number setting circuit 108. The input of a transmission circuit 120 has a high level owing to the high level of the signal 110. While the output of the circuit 120 is obtained by inverting the input level and drives a signal line 141 at a low level. As a result, the transmission/reception circuits 109 and 114 of both devices 105 and 106 are kept inactive and never start in a wrong state even in case both device 105 and 106 are mistakenly set at the same number.

Title: Driving force transmission
Inventor: SAKAI TOSHIBUMI
IPC: F16D43/284
Filed: 1990-05-22
Abstract: PURPOSE:To increase transmission torque according to increase in differential rotation speed and make variable the torque transmission by a relative rotation. CONSTITUTION:When relative rotation occurs between both propellor shafts 25, 26, viscous fluid in a reservoir R2 flows at a speed proportional to relative rotational speed. Then pressure in the chamber R2 increases gradually to push a working piston 13 in an axial direction thereby allowing a frictional clutch 10b to transmit torque proportional to differential rotation speed. A leaf spring 18 at the force end of a vane part is bent to reduce a gap with respect to a fluid chamber outer circumferential face 13 with fluid pressure when the relative rotation is in a specified direction and thereby the pressing force to the piston 13 is increased. When the relative rotation is another specified direction, the leaf spring is bent to increase the gap to reduce the pressing force to the piston 13. Thereby transmission torque is made substantially zero (0) to prevent seizure to the clutch 10b.

Filed: 1978-10-27
Abstract: PURPOSE:To simplify the inspection of characteristics, by eliminating the need for a cutting process of manufacture by separating the outer lead nose portions of a lead frame of a resin mold type semiconductor device from an outer frame and by connecting leads by means of a tie-bar and a support portion. CONSTITUTION:The outer lead nose portions 1 of a lead frame of a resin mold type IC are perfectly isolated from a frame outer frame portion 2. Lead portions are continuously connected by means of a tie-bar 3, and the tie-bar 3 and the frame outer frame portion 2 are connected means of a tie-bar deformed support portion 7. When molding an IC element portion with resin, a resin mold portion 4 and the outer frame are connected by means of a pair of connecting portions 6, 6' mounted to an inner surface of the outer frame. Since each outer lead is also separated mutually and electrically from the frame outer frame portion only by cutting the tie- bar 3 after molding, the electric characteristics of the IC can be inspected continuously and automatically only by contacting a measuring terminal with the leads.
