Title: Method for mounting electronic component
Inventor: YAMAMOTO HIROKI
IPC: H05K13/04
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To suppress degradation of production efficiency due to component shortage during production with collective suction. SOLUTION: When a Z-alteration operation is performed due to occurrence of component shortage at a part of a component group for collective suction, it is judged whether a mounting position of a component currently out of stock belongs to a group of collective suction. If it belongs to a collective suction group, a mounting position of the component currently out of stock as well as a group of mounting position of collective suction part are searched for, and an alteration process is so performed as to suck the suction position of the entire group from the group of another mounting position with the same component mounted, for continuous production operation with no degraded collective suction efficiency.

IPC: H01L21/48
Filed: 1982-01-14
Abstract: PURPOSE:To simplify the assembly and adjustment of a metallic mold and prevent damages of a sealed body, by providing cutting blades contacted on a resin sealed body only at the root of suspension pins. CONSTITUTION:The top ends 13a of the cutting blades 13 are contacted on the side edge 11a of the resin sealed body 11 only at the root 12a of the suspension pins 12, and the both side edges 11a away from the root 12a are separated from the blade tops 13a by a fixed interval.

Title: Plating method of gold alloy
Inventor: OZAWA KATSUHIKO
IPC: C25D5/10
Filed: 1981-01-16
Abstract: PURPOSE: To form a gold alloy plating film in a low cost, high corrosion resistance and abrasion resistance, and good appearance by increasing the agitating speed of a plating soln. continuously or intermittently at the stage of carrying out the gold alloy plating.  
     CONSTITUTION: At the stage of carrying out gold alloy plating of >40% Au such as Au-Ag, Au-Cu-Cd, Au-Ni, the agitating speed of the plating soln. is increased continuously or intermittently, for example, 0m/sec, 0.5m/sec, 1m/sec. This results in higher activity of Au ions by the agitation, gradually increased rate of deposition of Au, and increased gold phase, thus in spite of abrasion of the plating layer, the color tone changes gradually and therefore the need for excessive color checking in the worn part is eliminated. In addition, the gold alloy film of superior appearance, corrosion resistance and abrasion resistance is formed.
