Title: Gas bearing construction
Inventor: SUGITA TAKASHI
IPC: F16C32/06
Filed: 1982-02-13
Abstract: PURPOSE:To prevent the generation of a lock up phenomenon, by forming an annular gas supply groove communicated to a gas supply hole drilled to a different surface from a bearing surface in this bearing surface and diffusing gas injected into said annular gas supply groove to a whole area of said bearing surface. CONSTITUTION:A gas bearing consisting of a shaft 11 and a bearing 5 supporting this shaft 11 is constructed such that an annular gas supply groove 7 communicated to a gas supply hole 8 drilled externally of a bearing surface is formed in the bearing surface of the bearing 5, then gas supply fine grooves 9 extended from an inside of the bearing surface to the groove 7 and discharge gas fine grooves 10 extended along the axial direction from an outside of the groove 7 to an end part of the bearing surface are formed to either one of the surfaces of the shaft 11 or the bearing 5 located at a face-to-face position. Gas injected via the hole 8 is accumulated and filled in said groove 7 to diffuse fully in the bearing surface. As a result, even if the bearing is designed to provide a fine clearance (h), a lock up phenomenon is not caused, and self-induced vibration of swirl or the like generated at a high speed can be suppressed to substantially improve high speed stability.

Abstract: PURPOSE:To improve effective heat conductivity and to enable effective cooling of a sample by forming metallic thin film layers on both surfaces of an elastic heat conductor in order to obtain a heat conductive medium and interposing the heat conductive medium between the sample and a holder. CONSTITUTION:A heat conductive medium 8 obtained by forming metallic thin film layers 7 on both surfaces of an elastic heat conductor 2 is interposed between a platen 1 and a wafer 3. This heat conductor medium 8 is obtained, for example, when metallic thin layers 7 of aluminium, gold, silver, or the like are formed by performing chemical plating or vacuum evaporation or the like on both surfaces of the heat conductor 2 which is formed by mixing heat conductive corpuscles of alumina, carbon, gold, or the like with elastic and heat-resisting silicone rubber. Therefore, even if heat generation of the wafer 3 occurs by radiation processing of ion beams, the heat is transferred from the wafer 3 to the heat conductor 2 via one metallic thin film layer 7 of small heat resistance in the heat conductive medium 8, and the heat is transferred quickly to the platen 1 via the other metallic thin film layer 7 so as to perform cooling of this device. Hence, a temperature rise in the wafer 3 can be suppressed.

Abstract: PURPOSE:To enable formation of a sharp, minutely rugged appearance with distinct level difference, by providing a minutely rugged pattern composed solely of a foamed material or composed of foamed and non-foamable materials, directly on a backing paper. CONSTITUTION:A backing paper 1 may be an ordinary one provided with flame resistance. It is preferable, however, that the backing paper 1 is thicker than those commonly used as a backing paper for this kind of foamed sheets. A foamed material or non-foamable material constituting a rugged pattern 11 provided directly on the backing paper 1 is produced by printing a predetermined pattern with a foamable ink or non-foamable ink, followed by heating to effect foaming or fixing. Projected parts 3 of the rugged pattern 1 is free of the problem of being drawn by a coat layer, which problem would occur when the backing paper is coated, for example, with a polyvinyl chloride resin. Therefore, the projected parts 3 are left intact and a sharp, minutely rugged appearance with distinct level difference can thus be obtained.
