Title: Press working for lead frame
Inventor: YAMADA TORU
IPC: H01L23/50
Filed: 1987-03-05
Abstract: PURPOSE:To ensure an improved dimensional precision after a punching process by a method wherein the material is provided with a portion, to be punched away in the ultimate stage of pressing, whereinto some of the material under compression may escape during a V-groove forming process for a lead frame tab support lead. CONSTITUTION:In case a V-groove punch 1 is in the top force 2 of a metalmade press die, an escape groove 5 is to be provided beforehand at a prescribed position in the bottom force 4. Such an escape groove 5 is so positioned that it will receive the portion of material to be scrapped after the ultimate stage of press work on the lead frame material. When the press starts working and the V-groove punch 1 begins to bite into a portion of a lead frame 3, the portion of the material subjected to the compression goes easily into the escape groove 5. Stress within the Vgroove 6 is much less than in a design not incorporating an escape groove 5. In this way, the tab position in the lead frame 3 provided with the Vgroove 6 in its tab supporting lead 8 is ensured to be improved in dimensional precision.

Inventor: INAGAKI KATSUMI
IPC: B41M5/155
Filed: 1989-03-03
Abstract: PURPOSE:To obtain a color developer composition for producing pressure- sensitive recording paper superior in heat resistance and shelf stability by containing a polymer aqueous emulsion prepared by incorporating an aromatic carboxylic acid polyvalent metallic salt in emulsion particles and a pigment selected from among groups made of a clay, a hydroxide of zinc or aluminum, and an oxide of zinc or aluminum. CONSTITUTION:A color developer composition for pressure-sensitive recording paper contains a polymer aqueous emulsion prepared by incorporating an aromatic carboxylic acid polyvalent metallic salt in emulsion particles and a pigment selected from among groups made of a clay, a hydroxide of zinc or aluminum, and an oxide of zinc or aluminum. As the polyvalent metal used for synthesizing the aromatic carboxylic acid polyvalent metallic salt, zinc is especially preferable from the standpoint of color forming properties. The aromatic carboxylic acid polyvalent metallic salt is preferably added in the range of 2-100 pts.wt. per 100 pts.wt. of the polymer. The addition amount less than 2 pts.wt. results in a small effect of improving color forming properties. The addition amount more than 100 pts.wt. reduces a capacity as a binder.
