Title: Electroplating apparatus
Inventor: WATANABE YOSHIMI
IPC: C25D17/00
Filed: 1978-06-30
Abstract: PURPOSE: To prevent arc spark produced between supporting shafts and the object to be plated by injecting the solution of the same quantity as that of the bath solution in each cell to the supporting shafts or the object to be plated.  
     CONSTITUTION: The coil-from object A to be plated is passed onto supporting shafts 11 and are thereby suspended. As the supporting shafts 11 revolve, the object A to be plated spirally advance while making slide contact with each bath wall 2 and pitch guides 13, thereby subsequently pass through pretreating cells 3 thru 6 and plating cells 7. when voltage is applied between carbon contactors 12 and copper anodes 10 and the respective solutions are injected from bath injecting nozzles 15 to the supporting shafts 11, electrical conduction state between the supporting shafts 11 and the object A to be plated becomes good and the generation of arc spark is thereby prevented. The entry of the bath solution deposited on the supporting shafts into the other cells is prevented by the partition parts 16 provided to the supporting shafts 11.

Title: Auxiliary means for fitting ink ribbon
Inventor: HASHIMOTO HIROYUKI
IPC: B41J35/26
Filed: 1987-04-01
Abstract: PURPOSE:To enable the operation of fitting an ink ribbon to be smoothly performed and markedly reduce the possibility of smear of a printing paper, by providing glued parts to be disengageably engaged with each other, at both end parts of a ribbon-fixing band member. CONSTITUTION:When an end part of a fixing bend member 7 is pulled up in the direction of an arrow B, glued parts 7A are easily released from each other, and then the member 7 is taken out from a hole 6A. Next, an ink ribbon- fastening member 6 is pulled out in the direction of an arrow C, whereby an ink ribbon 2 is disposed at that position. An auxiliary means 5 for fitting the ribbon can be fitted and detached, and can be slidden along the ink ribbon 2, so that it has a degree of freedom in use, and ensures favorable workability. Since the ink ribbon-fastening member 6 which has a sheet-shaped form and is impermeable to ink is used to cover the ribbon 2, the ribbon 2 can be fitted without directly touching the ribbon by hands. Therefore, there is no possibility that the ink is adhered to the hands or the ink adhered to the hands smears a paper.
