Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To arrange rear ends of sheets in order by providing a first rear end regulation member which can move in the direction of sheet supply and feed and a second rear end regulation member which protrudes from a sheet loading face before sheet is supplied and fed by corresponding to rear end regulation positions of sheets having different sizes. SOLUTION: Manuscript is transferred in a bundle by a knocking shutter 41 at the same time with start of copying, a regulation plate 201 is raised by engaging the shutter 41 with a rear end regulation plate for A4 size 201 just before the transfer of the manuscript ends, and a hook member 203 is engaged to position the regulation plate 201. Upon completion of the transfer of manuscript in a bundle, the shutter 41 is returned to a stand-by position to prevent rearward deviation of the manuscript bundle on a tray 2 by the regulation plate 201 which is erected and fixed. The manuscript P1 is discharged from a manuscript discharge port 17, is dropped on the tray 2, and is put on the regulation plate 201 to transfer the manuscript P1 up to a predetermined position by the shutter 41 immediately after it is put on the regulation plate 201 so that rear ends of sheets are aligned. Consequently, it is possible to align the rear ends of sheets securely without relying on size of the sheets.

Title: Safety valve for battery
Inventor: IKEDA KOUNOSUKE
IPC: H01M2/12
Filed: 1980-07-09
Abstract: PURPOSE:To make a safety valve for a battery to work by the detection of battery temperature, and prevent any liquid leakage which might be caused during gas exhaustion, by fixing a metal piece having a different thermal expansion coefficient from that of a metal plate on either the inner or outer wall of the metal plate, near the thin parts provided on the metal plate. CONSTITUTION:A sealing lid 1 made of a metal plate is provided with thin parts 1' by forming annular ditches on parts of the lid 1. A metal piece 7 having a different thermal expansion coefficient from that of the metal plate, is fixed on the outer surface of the metal plate near the thin parts 1'. The sealing lid 1 is made of, for example, a stainless steel having a thermal expansion coefficient of 17X10<-6>cm/ cm/ deg.C, while the metal piece 7 is made of, for example, an invar having a thermal expansion coefficient of 1X10<-6>cm/cm deg.C. Owing to the difference between the thermal expansion coefficients of the metal piece 7 and the sealing lid 1, the temperature rise of a battery causes the metal piece 7 to be bent upward. As a result,  the thin part 1' of the sealing lid 1 is cut, and the battery is opened.
