Plating Device U.S. 2004262150 Toshikazu, Y.; Takashi, T, et al. Vertical plating of printed circuit boards and similar where a so- called regulation plate is perforat- ed sheet interposed between anode and cathode surface to improve current distribution and allow

improved plating into printed cir- cuit board through holes.

P o w d e r C o a t i n g D e v i c e a n d M e t h o d U.S. 2004255865 Morita, T; Mural, H., et al. Powder coating apparatus where pulse signal $2 of a low voltage generated by a pulse signal gener- ation circuit is boosted to a high voltage by means of a high voltage impression circuit, so that it is impressed upon corona electrodes. As a result, a corona discharge is intermittently generated from the corona electrodes toward an object to be coated, whereby powder coat- ing material sprayed from a nozzle opening of a gun main body in a forward direction is charged with negative ions developed by the corona discharge, whereafter it is

directed toward the object to be coated, and is deposited on a sur- face of the object.

Vacuum Carbo-Nitriding Method U.S. 2004250921 Yamaguchi, K. Multi-stage process including preheat, carburization, diffusion, and nitriding.
