Abstract: PURPOSE:To provide the target for production of an optical recording film having excellent recording, reproducing and erasing characteristics as well as high purity and high density and the process for production of such target. CONSTITUTION:Ge, Sb and Te having >=6N (99.9999%) purity are so weighed as to constitute GeSb2Te4 as a base alloy. These metals are put into a crucible made of high-purity carbon and are melted by effecting a heating reaction for two minutes at about 800 deg.C in a gaseous argon atmosphere. The molten metal obtd. in such a manner is poured into a casting mold and is rapidly cast to a flat plate shape of 5mm thickness, by which an intermetallic compd. of the GeSb2Te4 having the m. p. at about 605 deg.C is obtd. This intermetallic compd. is dry pulverized by a stamp mill and is classified to -150 mesh. The powder is packed into a container made of high-purity carbon and is sintered for two hours under 150kgf/cm<2> pressure at 560 deg.C in an atmosphere of a gaseous mixture composed of argon and hydrogen (Ar+4%H2). The sintered body obtd. in such a manner is machined to form the target having 100mm diameter and 5mm thickness.

Title: Microwave heating method
Inventor: WAKABAYASHI HIROSHI
IPC: H05B6/74
Filed: 1990-08-29
Abstract: PURPOSE:To contribute to the enhancement of an operating efficiency in heating and drying by covering a specified dielectric substance over a metal bar or a metal pipe in a jig for a heated article to be winded up in a roll shape. CONSTITUTION:In a jig, a heated article 7 is winded up over the surface of a metal bar 8 or a metal pipe 8a in a roll shape with a dielectric substance 9 where dielectric loss tangent sigma is the order of approximately 1.0X10<-2> or below. Microwaves are then uniformly irradiated over the surface so as to be heated and dried. When microwaves are irradiated onto the heated article 7, an electric field in the surface of the metal bar of the jig is close almost to zero. Microwaves are reflected, standing waves are then generated, and the electric field is however gradually intensified as it is parted from the surface of the metal bar 8. Standing waves come up to the peak value at a position apart from the surface of the metal bar by lambda/4. This thereby does not allow microwaves to be absorbed by the dielectric substance 9 section with which the metal bar 8 is covered, but does allow microwaves to be absorbed only by the heated article 7, the heated article is therefore sufficiently heated and dried.

Abstract: PURPOSE:To prevent contamination with foreign matter by disposing a preliminary vacuum chamber, partitioned through a porous wall having predetermined opening ratio from a vacuum chamber section, around the vacuum chamber and evacuating/leaking the preliminary vacuum chamber section. CONSTITUTION:When evacuating, air is sucked at first from the lower part of a preliminary vacuum chamber 32 followed by suction of air from the intermediate and upper parts. Consequently, air in a vacuum chamber section 31 is sucked through holes of surrounding porous wall 34 to the outside while furthermore sucked through an upper porous wall 35a to the outside of the vacuum chamber 31 as shown by an arrow 54. The preliminary vacuum chamber section 32 and the multiplicity of holes 34a, 35a function as dampers for moderating evacuation thus weakening the suction force through the holes 34a, 35a. Since the air in the vacuum chamber section 31 is sucked, uniformly with weak force, through a multiplicity of points in the surrounding and upper walls, rapid air flow in particular direction does not occur in the vacuum chamber section 31 thus preventing fly up of foreign matter.
