Title: Sheet post-processor
Inventor: KAWANO MINORU
IPC: G03G15/00
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To efficiently carry a sheet without stopping a sheet post-processor by timing-controlling a driving means of a carrier means for laminating first and second sheets sent from an image formation device and carrying them to an intermediate stacker. SOLUTION: A sheet P2-2 of a second sheet bundle hits the nip position vicinity of a carrier roller pair 21 in s stop state and stops, is laminated with the preceding sheet P2-1, and is ejected to the intermediate stacker 21 simultaneously. The tip end part of the last sheet of the preceding first sheet bundle P1 turns ON a stacker entrance sensor PS3, the motor driving rotation is decelerated after approx. 15 seconds, and the sheet carrying speed is reduced. Next, when the tip end part of the sheet P2-2 of the second sheet bundle turns ON the entrance sensor PS1, the motor driving rotation is restored from deceleration. Thus, the time until the carrying roller pair 21 is stopped is minimized before the tip end part of the first sheet following the second.

Title: Organic battery
Inventor: HORIE HIDEAKI
IPC: H01M10/058
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To restrain short-circuiting inside of a battery from proceeding even if a separating function of a separator between a positive electrode and a negative electrode is lost by interposing short-circuit preventing means made of a non-electron conductive substance between the positive electrode and the negative electrode. SOLUTION: A positive electrode having a positive electrode active substance 2 formed at one surface of a positive electrode current collector 1 is disposed opposite to a negative electrode having a negative electrode active substance 5 formed at one surface of a negative electrode current collector 4. In a organic battery in which a separator 3 is interposed between the positive electrode and the negative electrode, a coating layer 6 serving as short-circuit preventing means is formed on a separator side of the positive electrode active substance 2. In the organic battery such arranged as described above, even if the separator 3 is melted with, for example, an increasing temperature inside of the battery, the coating layer 6 having non-electron conductivity is hardly melted since a heat resisting temperature of the coating layer 6 is much higher than that of the separator 3.

Abstract: PURPOSE:To avoid the waste of paper by providing a feeding mechanism of a duplicating machine or the like with a detecting means of overlapped feeding and a separating means to separate one of overlapped papers and send it and others to an overlapped feeding cassette for preventing paper-clogging, picture deformation, and the like. CONSTITUTION:When overlapped feeding ocurs, one of the overlapped papers are separated by a pair of overlapped feeding separation rollers 36 and 36' and sent to a drum 8 by guides 40 and 40', while remained papers are collected into a cassette 105 by a plunger 100 through guides 101 and 101'. When two papers are supplied between these rollers, frictional forces between the roller 36 and an upper paper and between the roller 36' and an under paper are made greater than the frictional force between the two papers. Thereby, the roller 36' cannot be rotated by the rotational force of the roller 36, and only the upper paper can be conveyed. Meanwhile, a disk 156 with a plurality of preforations on the circumference is interlocked with the driven roller 36', and given detection by a photosensor 157. That is, when overlapped feeding occurs, it is detected as the disk 156 is checked in its rotation and pulse signals cannot be outputted.
