Title: Blank plug for bushing and fabrication thereof
Inventor: SEMA NOBUYUKI
IPC: H01R4/50
Filed: 1992-01-16
Abstract: PURPOSE:To enhance electrical characteristics by constituting a laminated insulator sheet of a cone part interposed between a high voltage side shielding metal and a low voltage side shielding metal and arranging the laminated face of the insulator sheet in parallel with the equi-potential face of the cone part. CONSTITUTION:A cone part 51 interposed between a high voltage side shielding metal 52 and a low voltage side shielding metal 53 is integrally laminated with an insulator sheet. The insulator sheet has lamination face 51A arranged substantially in parallel with an equi-potential face 70 formed at the cone part 51. EP rubber is employed as the insulator sheet, for example, which is then pressurized, heated and vulcanized to substantially integrate the laminated sheet. Since the lamination face 51A is substantially in parallel with the equi-potential face 70, dielectric breakdown does not take place along the lamination face 70 even if laminar voids exist in the lamination face 51A of the sheet. According to the invention, electrical characteristics are enhanced at the time of use.

Title: Pointer-type electronic clock
Inventor: SAKUYAMA MASAO
IPC: G04C3/14
Filed: 1992-01-17
Abstract: PURPOSE:To drive a minute pointer after a crown is pushed in to enable operation confirmation by driving a pointer indicator for a constant period when a changeover correction switch is returned from a correction mode to a normal mode. CONSTITUTION:When a crown is pulled out for correcting time, a position switch PS3a' is turned ON to have a divider circuit 5 and an optional divider circuit 6 reset. Thus time indication by a reduction gear train 10 is stopped. When the crown 3 is pushed in to a normal position after time correction is complete, reset states of the circuits 5, 6 are canceled and normal time indication is started, when a crown OFF detection circuit 11 is activated at the same time to output a detection signal S4. The signal S4 causes an operation confirmation signal generating circuit 12 to activate to have an operation confirmation signal S2 output. Then the signal S2 causes a converter driving circuit 8 to activate via an OR circuit 7, so that alternate driving pulses drive a step motor 9 to perform operation confirmation indication by the reduction gear train 10.

Abstract: PURPOSE:To make a paper jam easily dissolvable even if a conveying failure occurs to a recorded material by installing a space part for feeding in this recorded material at the time of abnormal recording operations, in a part of a conveyor means made takable out of a device body. CONSTITUTION:When a paper jam has occurred, those of paired conveyor rollers 45C, 46A, 47A, 47B at the upstream side in the recording paper conveying direction are made so as to be rotated as long as the specified time by a register roller pair 44 after a transfer drum 5 and this register roller pair 44 are stopped. Therefore, succeeding recording paper P2 gets slackening in an interval between the register roller pair 44 and the paired conveyor rollers 47A, 47B, and a conveyor guide 48D is largely turned round by means of paper stiffness whereby a space part S2 larger than an ordinary space part S1 is formed up therein, and the paper P2 is stopped in a state of being largely curved to the space part S2. So, a user opens a front door of the device body, drawing out a transfer conveyor unit 50A to somewhere short of this side, and thus the recording paper P2 conveyed next to the jam paper P1 is easily removable in this way.

Abstract: PROBLEM TO BE SOLVED: To execute the fixation of plotting within an extremely small-sized variable range by setting a white pad on the back surface of the plotted surface of a transparent film and feeding the transparent film in light energy so that the light energy transmitted through a part where graphic is not plotted may be irregularly reflected on the surface of the white pad. SOLUTION: By setting the white pad 2 on the back surface of the transparent film 1 where the graphic is plotted with ink or toner and irradiating the surface of the film 1 with the light energy, the light energy is transmitted through a transparent part where the graphic is not plotted and irregularly reflected on the surface of the pad 2. The irregularly reflected light energy is transmitted through the film 1 again and partially made incident on a boundary surface between the film and the ink or the toner with which the graphic is plotted, and converted into heat, so that the ink or the toner is fixed on the surface of the film 1. The area occupied by the graphic is extremely small and the light energy transmitted again is mostly transmitted through the film 1 and radiated to the outside.

Title: Control system for acceleration power supply
Inventor: MATSUOKA MAMORU
IPC: G05F1/06
Filed: 1987-02-09
Abstract: PURPOSE:To obtain a compact circuit together with reduction of the cost by controlling the voltage rise characteristics of an acceleration power supply based on the rise characteristics of an arc current. CONSTITUTION:When a switch 13 is closed, the current I of a constant current source 11 always flows through the switch 13 and no arc current iA flows. When the switch 13 is opened, the current I is shunted to a capacitor 15 and a load 14. In such a case, the current iA rises up in an exponent function curve of a time constant CR4 (C: capacity of the capacitor 15). When a switch 21 is closed at a time point t1, the voltage of a reference voltage generator 22 is applied to the input Y of a function generator 20. The generator 20 receives the information CRA on an arc power supply through the other input X. Then the generator 20 functions as the reference signal of an automatic control circuit 19 by an output Z serving as a proper function. A vacuum tube 17 controls the voltage Vacc of an output terminal 23 so that the other input of the circuit 19, i.e., the signal of a voltage divider 18 is coincident with the reference signal.

Abstract: PURPOSE:To execute automatically image formation processing by executing continuously and repeatedly form containable sheet number portion of an intermediate tray, as the maximum sheet number unit by a batch type, in case an image formed form sheet number exceeds the form containable sheet number of the intermediate tray. CONSTITUTION:A prepared transfer material is stored in an intermediate tray 38. When the form sheet number has reached a form-containable sheet number (m) of the intermediate tray 38, an operation for feeding out and returning an original is repeated with respect to the image formed transfer material in the intermediate tray until the original for forming an image comes to the same transfer material. When the operation has reached the original corresponding to the transfer material in the intermediate tray, the original is scanned, and an image formation is executed to the transfer material which has fed out in order from that of the lowest part of the transfer material in the intermediate tray. The original on which the image formation has been executed once is discharged, and with respect to the next original, too, the same operation is executed, and it is repeated by the number of the transfer materials in the intermediate tray. In case when the counted original exceeds the form containable sheet number (m), (a) is reset to '0'.
