Title: System for shifting and machining electrode plate
Inventor: KONDOU YASUHIKO
IPC: H01M4/80
Filed: 1979-07-19
Abstract: PURPOSE:To maintain a constant slack and thereby eliminate the configuration and elongation of a long base-plate by equipping a strain detector and a slack detector: the long base-plate is turned back in accordance with the works by detectors when the base plate is unrolled and shifted. CONSTITUTION:A rolled base-plate 1 on a supplying roll 2 is unrolled and shifted by a traction caused by a winding roll 3; the base plate 1 is used for electorde plates. If a horizontal shifting part 1a is strained, a strain detector 11 detects the strain, and a motor 10 is driven. This causes the rolled base-plate 1 on the supplying roll 2 to be unrolled, shifted and supplied at a fairly high speed toward the direction shown by the arrow, resulting in periodic slacks in the horizontal shifting part 1a. A slack detector 12 works when a fixed slack arise, and the rotation of the motor 10 is stopped. The following rotation of the roll 3 cause a traction , with diminish the slack of the horizontal shifting part 1a. Then the former condition is repeated.

Filed: 1987-04-14
Abstract: PURPOSE:To facilitate the matching of an image frame of a negative film with an image printed on photosensitive paper by adding an identification mark corresponding to the image of the negative film to the photosensitive paper. CONSTITUTION:When a notch is detected timing with the detection of an image frame, the image frame corresponding to the notch needs to be printed, so the negative film 18 is stopped from being conveyed after the frame is positioned at a printing position. When, however, the notch is not detected, a jump to a next step is made.

Consequently, frame numbers given previously to images match with image frame identification marks and image frames are easily made to correspond to prints. Thus, the image frame identification marks corresponding to images printed on the photosensitive paper 33 are given, so image frames are easily selected at the time of reprinting operation, etc.

Filed: 1988-04-14
Abstract: PURPOSE:To prevent exhaustion to areas besides the stacking position and provides an uniformly stacked condition, by varying the inclined angle of the exhaust part of an elevating/sinking conveyor, and miltigating the exhaust angle of corrugated cardboards to be exhausted from the exhaust part. CONSTITUTION:The inclined angle of the exhaust part 14 of an elevating/sinking conveyor 5 is changed by folding mechanism 13, 13a in compliance with vertical motion of the conveyor 5, and the exhaust angle of a corrugated cardboard to be exhausted from the exhaust part 14 shall be miltigated.
