Patent number: 6595844Abstract: A core drill having a shank and a cup shaped base metal section constructed of a disk shaped top wall and a cylindrical side wall provided on a fore-end of the shank. A grinding stone portion is mounted on an outer end part of the base metal section, with abrasive grains fixed to the outer end part of the base metal section. Abrasive grain layers are formed in a spiral pattern on inner and outer side surfaces of the cylindrical side wall of the base metal section, with abrasive grains fixed to the inner and outer side surfaces of the cylindrical side wall thereof. When the grinding stone portion is put into rotational contact with a workpiece, the workpiece is ground through to form a circle hole in section leaving a cylindrical core therein.Type: GrantFiled: November 8, 2000Date of Patent: July 22, 2003Assignees: Atock Co., Ltd., Shin-Etsu Quartz Products Co., Ltd., Yamagata Shin-Etsu Quartz Co., Ltd.Inventors: Toru Mizuno, Ikuo Hattori, Akihiko Sugama, Toshikatsu Matsuya, Yoshiaki Ise

Patent number: 6209353Abstract: A known method for producing an object having a flanged tubular portion at the outer periphery, comprises supplying a continuously extended, cylindrical body made of the flange material to a welding zone at the tubular portion of the object and welding the flange material to the welding zone by heating and winding the cylindrical body around the object.Type: GrantFiled: February 25, 1998Date of Patent: April 3, 2001Assignee: Heraeus Quarzglas GmbH & Co. KGInventors: Toshikatsu Matsuya, Yoshiaki Ise, Shoji Takahashi

Patent number: 6203416Abstract: Provided are an outer-diameter blade, an inner-diameter blade and cutting machines using both blades for cutting hard material, and a core drill and a core-drill processing machine for forming a hole into hard material, whereby the mechanical processing with reduction in the cutting and/or contact resistance to the tools is realized, so that in the case of the outer-diamond blade, it is prevented from occurring that a to-be-cut object is warped and put into contact to the blade to cause chipping; in the case of the inner-diameter blade, it is prevented from occurring that the blade is bowed and/or a cutting surface is curved; and in the case of the core drill, not only are grinding powder of a workpiece and loosed-off abrasive grains effectively removed to prevent those from being loaded between the drill and the workpiece, but neither of cracking and chipping occur when the drill passes through the workpiece.Type: GrantFiled: September 7, 1999Date of Patent: March 20, 2001Assignees: Atock Co., Ltd., Shin-Etsu Quartz Products Co., Ltd., Yamagata Shin-Etsu Quartz Co., Ltd.Inventors: Toru Mizuno, Ikuo Hattori, Akihiko Sugama, Toshikatsu Matsuya, Yoshiaki Ise

Patent number: 5640282Abstract: A light-weight base body of a reflecting mirror, such as those used in reflecting astronomical telescopes, is proposed which is made from fused silica glass or high-silica glass and is advantageous in respect of the excellent thermal and mechanical stability in dimensions to ensure high performance of the reflecting mirror. The base body is composed of a front plate, i.e. a surface plate to provide the optical surface, and a supporting body of porous foamed glass integrally bonded to the front plate. These two parts of the base body can be bonded together by sandwiching a layer of a finely divided silica powder therebetween and heating the assemblage at a temperature higher than the softening point of the silica powder so that the silica powder is softened or melted to firmly join the two parts sandwiching the powder layer.Type: GrantFiled: October 11, 1991Date of Patent: June 17, 1997Assignee: Shin-Etsu Quartz Co., Ltd.Inventors: Yoshiaki Ise, Hiroyuki Miyazawa, Hiroyuki Kimura, Shinichi Okoshi, Tatsumasa Nakamura, Toshiyuki Kato

Patent number: 5563743Abstract: The invention provides a light-weight base body of a reflecting mirror such as a mirror in a reflecting astronomical telescope, which is very stable not only thermally but also mechanically and is highly resistant against adverse environmental influences. The mirror base is composed of a porous foamed disc body of fused quartz glass or high-silica glass sandwiched by two plates of fused quartz glass or high-silica glass, of which one is made from transparent glass and serves to provide an optical surface having flatness or a specified curvature, and the side surface of the porous foamed disc body is protected against environmental influences by providing an air-tight sealing layer formed from a silicone rubber-based sealing agent or a thin sheet of fused quartz glass or high-silica glass.Type: GrantFiled: April 7, 1995Date of Patent: October 8, 1996Assignees: Shin-Etsu Quartz Co, Ltd., Okamoto Optics Work, Inc.Inventors: Tatsumasa Nakamura, Yoshiaki Ise, Yoshiaki Okamoto
