Patent JP-S62115682-A (JP)
Title: Electric contactor such as motor brush containing intercalated graphite
Inventor: FUERUDEINANTO RINKAAN FUOOGERU
IPC: H01B1/04
Filed: 1986-08-27
Abstract: An electric motor brush or other electrical contact fabricated with intercalated graphite exhibits improved electrical conductivity, strength and performance when compared with electrical brushes made with non-intercalated graphite or with carbon. Such contacts may be formed by filling a mold of the appropriate shape with intercalated graphite powder and applying sufficient pressure and heat to produce a coherent mass. The ability of intercalated graphite powder to be compacted in such a fashion leads to economic methods of manufacturing electrical contacts. The properties of these contacts may be further improved by the incorporation of metal powder, organic polymers or ceramic powders into the intercalated graphite prior to pressing.

IPC: H05K3/28
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To obtain a multilayer printed-wiring board in which the close contact strength of an inner layer is enhanced by a method wherein a thermosetting adhesive layer is brought into close contact with a pattern formation face by a hot pressing operation via a base film, a hole is made in the adhesive layer and an outer-layer conductor pattern is formed on the adhesive layer. SOLUTION: Every adhesive dry film 10 in which every thermosetting adhesive layer 6 is protected by every base film 12 is arranged. Then, every adheisve layer 6 is brought into close contact with every pattern formation face by a hot pressing operation via every base film 12. When heat and pressure are applied to every thermosetting adhesive layer 6 in a hot pressing process in this method, every thermosetting adhesive layer follows every pattern formation face which contains uneven parts, and every adhesive layer 6 is hardened in this state. Consequently, air bubbles are hardly left in a part near the lower part on the side face of every inner-layer copper pattern 3. In addition, every adhesive layer is buried sufficiently in every needlelike blackening reduction layer 4 which is formed on every inner-layer copper pattern 3.

Abstract: PURPOSE:To perform multicolor printing transfer without drying ink at every color and to relatively rapidly apply a pattern even to an object to be transferred having complicated unevenness without requiring even a printing plate by applying activators imparting tackiness to fused toner. CONSTITUTION:The original picture is copied on a water-soluble or water- swellable film to obtain a desired pattern film 3. The film is floated on the water surface 41 of a water tank 4 so that the pattern is turned upwardly and, after the film absorbs water to swell after floating but before transfer, an activator 5 is applied to the film from a sprayer 50 by spraying. During a time when this pattern has tackiness and spreadability, an object 6 to be transferred is allowed to fall along with the film from the water surface 41 to be pushed in water.
