Inventor: KATAYAMA AKIRA
IPC: C23C14/58
Filed: 1990-04-26
Abstract: PURPOSE:To improve chipping resistance by generating a fine crack in the coating of a coated cemented carbide for which a coating comprising at least one layer of ceramic selected from carbide and the like such as Ti as a tungsten carbide base cemented carbide, is coated. CONSTITUTION:A fine crack is necessary for a coated cemented carbide comprising at least one layer of ceramic of at least one species selected from carbides, nitrides, nitride-carbides of Ti, Zr, Hf, Nb, Ta, Cr, Mo, and Al2O3, so as to improve chipping resistance. Since the chipping resistance is drastically deteriorated when the depth of crack penetration in the cemented carbide exceeds 5 micrometer, the coating depth of crack penetration is defined as not less than the thickness of coating in a vertical direction from the coated surface, and not more than the thickness of coating plus 5 micrometer. The average value of the crack width is not more than 2 micrometer, and when the value exceeds this level, the chipping resistance will be improved, however abrasion resistance will be drastically reduced. When the average crack distance is not less than 10 micrometer, the release of residual stress is insufficient, while, when it is less than 5 micrometer, since the abrasion resistance is reduced, the crack distance is defined as not less than 5 micrometer, and less than 10 micrometer.

Title: Intranetwork subscriber state reporting system
Inventor: FUJITA MUNENORI
IPC: H04M7/00
Filed: 1993-04-12
Abstract: PURPOSE:To provide the intranetwork subscriber state reporting system for which report processing is simplified by normally periodically reporting a subscriber state to an opposite subscriber storage exchange. CONSTITUTION:The subscriber state of end-end (a state between subscribers 300 and 301) is reported by exchanging frames in a fixed cycle between call originating and incoming subscriber storage exchanges 200 and 203. Assuming that the state report frame is lost in the middle, non-coincidence is not generated in the subscriber state management information of end-end by reporting the state with the state report frame in the next cycle. Sometimes, the state management information is easily lost when restarting or breaking the exchange, and it is difficult to recover the non-coincidence by the report depending on an event such as a fault or congestion. Even at the time of this restart or fault, the state of end-end can be made coincident by the periodical report after the exchange is recovered.
