Title: Manufacture of cutting tool made of rigid layer-covered tungusten carbide group cemented carbide alloy
Inventor: SAWADA YOSHIHIRO
IPC: B23P15/28
Filed: 1990-06-29
Abstract: PURPOSE:To provide a rigid layer having excellent adhesion to an alloy base substance surface by covering the surface of a WC group cemented carbide base, produced by applying annealing treatment in specified temperature vacuum atmosphere after mirror polishing is applied on a surface to provide specified coarseness, with a rigid layer by a chemical deposition method. CONSTITUTION:Mirror polishing is applied on the surface of a tungsten carbide group cemented carbide base substance so that surface coarseness is reduced to 0.2mum or less (O.2S or less). After the base substance is annealed in vacuum atmosphere having a temperature of 1000-l300 deg.C for 5-30 minutes, the surface thereof is covered with one monolayer or two or more kinds of composite layers of titanium carbide, nitride, carbon nitride, and aluminum oxide and a solid solution thereof. By vacuum annealing, Co adhered on a WC particle surface on a mirror-polished surface is removed and rupture chips of WC particles pressed in Co being a coupling phase is dissipated and washed. Therefore, when a rigid layer is formed on the surface of a base substance, a eta-phase is hardly produced at an interface between the WC group cemented carbide base substance and the rigid layer and the rigid layer having excellent adhesion is formed.

Title: Magnetic paint kneader
Inventor: OISHI SEIJI
IPC: B29B7/58
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To automatically and precisely detect the vacancy of a magnetic paint without the visual confirmation of an operator. SOLUTION: The torque corresponding to the load of an extruder driving motor 22 is monitored by a vector control inverter 40, a previously given lower limit of torque is stored in a vacancy detecting part 55, and the stored lower limit is compared with the torque received from the inverter 40 through a torque detecting part 54. When the monitored torque becomes lower than the lower limit, the exhaustion of the magnetic paint in the extruder 20 is judged by the vacancy detecting part 55, and a vacancy detection signal is emitted. When the vacancy detection signal is emitted from the detecting part 55, the monitors 12 and 22 are stopped by the operation control parts 53 and 58 of a controller section 130. Since the torque of the extruder corresponding to the amt. of the magnetic paint supplied, the vacancy is also detected with accuracy.
