Patent JP-S62125372-A (JP)
Title: Laser engraving machine
Inventor: NINOMIYA YUKI
IPC: G03G15/06
Filed: 1985-11-27
Abstract: PURPOSE:To prevent the generating of the position dislocation at the time of the laser exposure by providing the guide with curved surface and the opposite electrode with curved surface in a developer and passing through the photoconductive sheet between these. CONSTITUTION:Since a developer 30 accommodates a developing solution, it is positioned to the lowest out of conveying paths. For such a reason, the conveying path is not horizontal and bent on the way so that the path can be likely to rise after the developer 30. Consequently, when the photoconductive sheet is bent when it passes through the developer, a photoconductive sheet 32 passes through between a lower guide plate 78 smoothly bent and a curve opposite electrode 80, and therefore, the sheet can smoothly pass in the developer 30. As the result, while the tip of the photoconductive sheet passes through the developer 30, even when a laser exposing part 62 forms a static latent image at the rear edge, since conveying is smoothly executed, the position dislocation at the time of the laser exposure can be prevented.

Title: Overload preventing device for hoist
Inventor: SATO MASAAKI
IPC: B66D3/20
Filed: 1994-11-01
Abstract: PURPOSE: To maintain a protection state through reliable holding of the operation state of an overload protection relay and to facilitate release of a protection state after an overload is eliminated by providing a self holding release button switch to release the self holding state of an overload protection relay. CONSTITUTION: When an overload state occurs during winding operation, by pressing a winding press button switch 2, a microswitch 28 is closed. By energizing an overload protection relay 30, an electromagnetic switch contact 36 for winding is opened to stop a motor 38. In this case, the overload protection relay 30 closes a self holding contact 34 to effect self-holding. In following operation, by operating a winding-down press button switch 4, winding-down operation is effected. However, since self-holding of the overload protection relay 30 is not released, response to winding operation is not effected. When an overload is eliminated and a self holding release button switch 35 is pressed to effect opening, hoisting operation is practicable.
