Title: Conductive silver paste
Inventor: KARASAWA MINAHITO
IPC: H01B1/22
Filed: 1988-12-06
Abstract: PURPOSE:To obtain a monoliquid-type electrically conductive silver paste with low resistance, good adhesion to a substrate, excellent storage stability as well as screen-printability, heat resistance, and humidity resistance by using an amino resin and a modified epoxy resin together as a binder of the conductive silver paste. CONSTITUTION:The title paste is composed of a silver-based conductive powder, an amino resin, and a modified epoxy resin. As the amino resin, melamine resin, especially partly butylated melamine resin, is excellent, for it has good curability and hardness after cured. Also, as the modified epoxy resin, a conventional multivalent epoxy resin may be used and a glycidyl compound-novolak epoxy resin such as phenol-novolak, cresol-novolak, etc., is preferable owing to its heat resistance and electric properties. As a result, a monoliquid-type electrically conductive silver paste with low resistance, good adhesion to a substrate, excellent storage stability as well as screen-printability, heat resistance, and humidity resistance is obtained.

Title: Wheel cap
Inventor: TERAMOTO YASUNOBU
IPC: B60B7/02
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To prevent a lowering of appearance quality of a wheel without injuring cooling performance of a brake. SOLUTION: A wheel assembly 1 is provided with a wheel body 2 comprised of a rim 5, a center plate 7 and a plurality of spoke portions 8 and a wheel cap 3. The wheel cap 3 is of a circular shape so as to cover almost all of a design surface side of the wheel body 2 and covers opening portions 11 between the spoke portions 8. On the corresponding portions to the opening portions 11, a lot of fine through holes 12 are formed. Therefore, a heat generated inside of the wheel body 2 is easy to escape outwardly and it is inhibited that the heat is stayed inside of the wheel body 2. Further, since the inside of the opening portions 11 is not visually confirmed from the outside, even if a brake rotor is rusted, the rust is not visually confirmed from the outside.
