IPC: B41J2/045
Filed: 1989-04-17
Abstract: PURPOSE:To obtain a high printing quality ink jet head by realizing a uniform ink reservoir on a nozzle surface by a method wherein blind hole structural dummy nozzles are established between respective nozzles and outside an upper most and a lowest ink nozzles. CONSTITUTION:In an ink nozzle groove 5 which is connected to a pressure chamber and an ink supply preparatory chamber and forms an ink nozzle line, etched grooves 6 finally becoming blind hole structured dummy nozzles are arranged at a center of each ink nozzle groove 5 and respectively outside an upper most and a lowest ink nozzle grooves 5.

IPC: B66B7/02
Filed: 1985-05-10
Abstract: PURPOSE:To restore the ductility of the part which became brittle with its cleavage by re-crystalizing with cooling after heating locally the both leg parts formed by cleaving the end face of a metallic strip sheet by a wedge shaped tool. CONSTITUTION:Leg parts 1A, 1B are formed by cleaving a metal strip sheet 1 by a wedge shaped tool 2. In this case, a work hardening is caused by the pushing-in of the wedge shaped tool 2 on the cleaved part 3 and the surface layer part becomes hard and brittle. The work hardened part 3A is subjected to an annealing and normalizing by cooling it after heating by the flame 4A of a torch 4 since a crack may cause on the work hardened layer if it is elongated in T shape as it is. By performing said heat treatment, the mechanical property is restored with the recrystalization of the work hardened layer 3A and the crack is difficult to cause on the work part 3B even in case of forming in T shape by performing the bending thereafter.
