Title: Method of forming single crystal region, and single crystal article using same
Inventor: YAMAGATA KENJI
IPC: H01L21/76
Filed: 1989-10-11
Abstract: PURPOSE:To isolate a single crystal film in an optional position and with optional area by forming a mask layer, which has a projection, on a single crystal face such as a relatively cheap Si wafer, or the like, and opening the enough small area of the mask layer other than the projection so as to make an opening, and growing a single crystal with the exposed single crystal face as the center. CONSTITUTION:Masks 12 with irregularity are applied cyclicly on a substrate such as an Si wafer, etc., and fine openings 13 are made at the recesses. Next, with the fine opening 13 as the center, an Si crystal is epitaxially grown. Next, the selective polishing of the Si crystal is done. As the selective polishing method, a selective polishing method, which makes use of the features that the polishing speed is remarkably different between Si and SiO2 by mixing special chemical polishing liquid, can be used in the case where the mask is SiO2. In the case that the mask is Si3N4, a mechanical polishing method can be used. The etching of the mask 12 is done. This is done by dipping the substrate in etchant for one hour to several tens of hours. Next, the whole is oxidated, and a single crystal region 14 being the growth part is isolated from the substrate. Next, the SiO2 layer at the surface is etched. It finishes at the point of time when the top 19 of an Si single crystal film 18 is exposed.

Title: Brake drum for drum brake
Inventor: KONNO TSUNEO
IPC: F16D65/10
Filed: 1990-10-02
Abstract: PURPOSE:To prevent a brake from working insufficiently or one-sidedly by forming a coat consisting of at least a part of components of frictional members on the inner circumferential surface of the peripheral wall of a brake drum. CONSTITUTION:Though the inner circumferential surface of the peripheral wall of a drum has roughness of about 10mum, the roughness can be made small by applying a coat on this inner circumferential surface. Even if a honing process is carried out generally, the roughness of more than 10mum still remains on the surface, but it has an advantage of making a seemingly coarse-grained surface a fine-grained ones by carrying out a coating. Furthermore, coat members applied on the inner circumferential surface are constituted from a part or the whole of components of frictional members. Thereby, the stability of initial validity can be realized.
