IPC: C04B37/02
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To obtain a circuit base plate for a power module excellent in peeling strength and a high heat cycle property by keeping a mass ratio of B in BN remaining in the surface layer of a ceramic base plate consisting of a nitride as a main component to a set value or less. SOLUTION: This circuit base plate for a powder module using a ceramic base plate consisting of a nitride such as AlN or Si3 N4 as a main component, uses a base plate having <=50×10<-6> B/Al ratio and <=50×10<-6> B/Si in as ratios of major metal components in the ceramic to B in BN remaining in the surface layer measured by intensity ratios of a fluorescent X-ray. The circuit base plate having a prescribed circuit is obtained by joining a copper plate to at least one of the circuit base plate through a solder containing at least one kind of active metals of Ti, Zr and Hf by firing in vacuum, and performing an etching treatment.

Title: Electric discharge machining of roll-shaped work
Inventor: KAWANO MITSUGI
IPC: B23H9/04
Filed: 1983-12-26
Abstract: PURPOSE:To make it possible for the useful length of a roll to be automatically set when a type of roll is preset by detecting the end of a roll in the electric discharge machining method of a roll for cold rolling to satin-finish a steel band. CONSTITUTION:An end machining special head 20 is lowered from its specified position and stopped at the discharge start position. Based on the transfer distance at this time, a roll diameter detector 21 detects the diameter D of the roll, and this detected roll diameter is sent to an arithmetic circuit 22. The arithmetic circuit 22 has previously stored the diameter DA and useful length LA of a new roll and the diameter DB and useful length LB of a disused one, and, from these data and the roll diameter D, the useful length L of a roll 3 is obtained. This useful length L is given to a feed control circuit 23 as a standard value, starting the electric discharge machining. When the end machining special head 20 reaches the end, the control circuit 23 functions to stop the feeding. Thus the whole surface is uniformly satin-finished by the head 20.
