Title: Plating method of surface copper foil of printed board
Inventor: KUROSAWA KEIJI
IPC: H05K3/38
Filed: 1984-08-31
Abstract: PURPOSE:To reduce the size of a plating cell and to diminish the installation area of the plating cell in electroplating of copper to the copper foil on the surface of a printed board by forming an anode of a belt-like body and moving said anode so as to cover the metallic surface to be plated. CONSTITUTION:Rails 8 supported horizontally to the plating cell 1 are formed to the length larger than the length on the other side of the printed board 3 to be plated. A driving part 7 is imposed on said rails. The part 7 is made movable on the rails 8 by a driving source and the anode 5 of the copper which is the belt-like body is attached to the part 7. The part 7 is positioned toward the left end and the board 3 is supported horizontally. The anode 5 is the belt- like body made to about 1cm width and therefore the area occupied by the cell 1 for the purpose of the anode 5 is small. While electrolytic current is conducted to the anode 5 together with the board 3, the anode 5 is moved back and forth on the rails 8, by which the copper is electrolytically plated to the copper foil 4 surface of the board 3.

Title: Toner for flash fixing
Inventor: KO KATSUJI
IPC: G03G9/093
Filed: 1986-08-05
Abstract: PURPOSE:To improve filming resistance and fixability and to obviate the generation of voids at the time of fixing by coating a toner consisting of a styrene/ acrylic resin as a base material on a toner consisting of an epoxy resin as a base material. CONSTITUTION:The toner consisting of the styrene/acrylic resin as the base material is coated on the toner consisting of the epoxy resin as the base material. The number average mol.wt. of the epoxy resin is preferably 1,000-4,000. The toner consisting of the styrene/acrylic resin as the base material preferably contains an electric charge controlling agent such as nigrosine dye and the number average mol.wt. of the styrene/acrylic resin is preferably 6,000-3,000. Since the styrene/acrylic resin having a high m.p. covers the surface of the toner prior to fixing, the toner has the excellent filming resistance. The shells of the styrene/acrylic resin are ruptured and the inside epoxy resin contributes mostly to the fixability at the time of fixing; therefore, the excellent fixability is obtd. Since the styrene/acrylic resin is slightly contained in the toner, the melt viscosity increases and the generation of voids is suppressed.
