Title: Coating method of hybrid ic
Inventor: MIYAMOTO HIDETOSHI
IPC: H05K3/00
Filed: 1983-07-12
Abstract: PURPOSE:To eliminate the occurrence of a crack or air bubble in a coating film by preheating a hybrid IC or a coating solution to be coated on a hybrid IC at a temperature which does not harden the solution before hardening the solution. CONSTITUTION:Before coating solution is coated on a hybrid IC, the IC is preheated. The preheating is executed at the temperature lower than the temperature for hardening the solution. Then, the preheated IC is dipped in the solution to coat the solution on the surface, ultraviolet rays are emitted to the IC to harden the solution, thereby forming a coating solution. Thus, if the IC is preheated before coating the solution, the viscosity of the solution can be reduced. Accordingly, the thickness of the coating film can be equalized, and a crack does not occur. Further, since viscosity of the solution decreases, air bubbles produced in the solution can be readily extracted, and the air bubbles do not accordingly remain in the film.

Title: Cemented carbide for cutting tool
Inventor: OHATA HIROSHI
IPC: C22C29/08
Filed: 1993-05-28
Abstract: PURPOSE:To produce cemented carbide having excellent wear resistance and chipping resistance to a hard-to cut material such as stainless steel, in cemented carbide obtd. by adding the carbides or the like of specified elements to a WC-Co system by controlling the solid solution quantity of W and C in a bonding phase. CONSTITUTION:This cemented carbide for a cutting tool is constituted of a bonding phase contg. at least, by weight, 1 to 15% Co and a hard phase constituted of <=15% of one or more kinds among the carbides, nitrides and carbonitrides of 4a, 5a and 6a group elements excluding W, and the balance WC. Then, the quantity of W and C entering into solid solution in the bonding phase is respectively regulated to 1 to 15% and <=5% to the total quantity of the bonding phase. In the case of <1% solid solution quantity of W, the solid-solution strengthening of the bonding phase is insufficient to deteriorate its wear resistance, and welding is increased from the viewpoint of reaction resistance. In the case of >15%, the bonding phase is made brittle. In the case of >5% solid solution quantity of C, the m.p. of the bonding phase is reduced, and its affinity with the material to be cut is increased to cause the increase of welding at the time of milling and the chipping of the edge.
