Abstract: PROBLEM TO BE SOLVED: To effectually remove a non-porous Si region on a porous Si region in an SOI(silicon on insplator) substrate, prevent a glass substrate from being etched, and eliminate the need of increasing the area of the porous Si region. SOLUTION: The present method comprises the processes of making porous a surface of a single crystal Si substrate and forming a porous single crystal Si region 101 on a non-porous single crystal Si region 100, forming a second non-porous single crystal Si region 102 on the surface of the foregoing region 101, sticking the surface of the foregoing region 102 and a support substrate 110 on the same surface together through an insulating region 103, removing the foregoing region 100, and removing the foregoing region 101. In this case, the foregoing process of removing the foregoing first non-porous single crystal Si region 100 is adapted such that there is performed dry etching where an etching rate of the non-porous single crystal Si region 100 is larger than that of the porous single crystal Si region 101.

Title: Rotary anode x-ray tube and manufacture thereof
Inventor: MARUMO HITOSHI
IPC: H01J35/16
Filed: 1990-11-29
Abstract: PURPOSE:To prevent decrease in the lubricating performance with only a small rise in temperature of the bearing portion following increase in output of the X rays, by manufacturing a connection shaft made of sintered material through performance of the process steps including a rotary grinding step. CONSTITUTION:The connection shaft directly receives heat from an anode target, so that it increases in temperature. Therefore, it is made of sintered material containing molybdenum and tungsten, as main components, which have high resistance to high temperature. And the connection shaft 4 is formed into a tubular configuration through performance of, for example, rotary grinding operation. When carrying out the rotary grinding operation, a tubular member 20 having a wall thickness of several millimeters is first fitted over a mold 21 and is rotated integrally therewith. Then, a rotating member such as a roll 22 is pressed against the outer peripheral wall surface of the tubular member 20 in a state wherein it is contacted therewith. Then, the wall surface of the tubular member 20 is ground by this roll 22 along the axis of the tube to extend the tubular wall while this wall is made thin, thereby forming a hollow connection shaft 4 of a specified wall thickness. Since the crystal grains of the sintered material are finely granulated and so the connection shaft has a very high strength, reduction in cross-sectional area thereof and increase in heat resistance are possible to make it possible to suppress rise in temperature of the bearing portion to a very small value.
