Title: Method for controlling collator for use in copying machine or the like
Inventor: MIYASHITA KIYOSHI
IPC: G03B27/00
Filed: 1980-07-14
Abstract: PURPOSE:To obtain a collator control method simple in construction and easy in operation, by rendering a collator mode inoperable when the position of a collator initially set manually is not in a home position. CONSTITUTION:When a microswitch 55 for copy detection is turned on by the forward end of the first copy, one low level pulse is issued from a NAND gate 204 and fed to the clock terminal of D type FF 212 through a NOR gate 210 FF 212. When a collator is not manually set to a home position, an output of FF 212 remains at low level with a microswitch 57 for detecting the home position, resulting in leaving D type FF 227 always in a clear state through an AND gate 232, and an output terminal 239 remains at high level. Therefore, a collator drive motor is not energised, and the collator mode remains inoperable, thus permitting the collator mode to be executed only when the collator is set to the home position by manually moving it, and this collator control method to be simple in construction and easy in operation.

Title: Current transformer
Inventor: OKUBO YASUHIKO
IPC: H01F38/28
Filed: 1988-04-19
Abstract: PURPOSE:To reduce a residual voltage at a low cost without extra materials, parts and additional treatments by deviating the starting and ending portions of winding of a belt type iron core wound concentrically only by an angle within the specific range on the concentric circles. CONSTITUTION:In zero phase current transformer having a belt type iron core 1 wound concentrically, the starting and ending portions of wound iron core 1 are deviated concentrically by 90 deg. to 270 deg.. For instance, the PC permalloy (phi41Xphi37X5HX0.1<t>) is used as a material of wound iron core 1, it is then wound concentrically and the urethane where (phi0.1) is wound uniformly for 100 turns to the winding to form a zero phase current transformer. Thereby, generation of residual voltage can be suppressed more effectively than the case where the internal end 2 matches the external end 3 of the wound iron core 1. Particularly when both ends are deviated by 180 deg., most effective reduction effect of residual voltage can be obtained. Moreover, in the case of wound iron core 1 located near the radius direction where the ratio of external and internal diameters is almost equal to 1, such suppression effect is large.
