Patent number: 6414373Abstract: A high-resistance substrate with good RF characteristics, which has an interstitial oxygen concentration ([Oi]) of 8E17 cm−3 or less, an oxygen precipitate density ([BMD]) of 1E8 cm−3 or more, and a substrate resistivity of 500 &OHgr;·cm or more is used. A heat-treating step of the device process is performed for 25 hrs or less as a value calculated assuming that the temperature is 1,000° C. This suppresses a decrease in the resistance of the substrate, prevents crystal defects such as slip, and improves the yield.Type: GrantFiled: June 25, 2001Date of Patent: July 2, 2002Assignee: Kabushiki Kaisha ToshibaInventors: Hiroaki Yamada, Osamu Fujii

Patent number: 5806163Abstract: In forming an element-free space portion in a continuous fastener chain, legs of a number of metallic fastener elements, which legs exist on one side of the fastener chain are cut by a pair of cutting blades, and then coupling heads of the fastener elements and the legs extending from the coupling heads and existing on the other side of the fastener chain are removed from cores of fastener tapes while being clamped by a punch and a die. Therefore, it is possible to remove the fastener element portions from the fastener tapes without damaging the cores and not to require so high precision in positioning the fastener elements at a cutting station, thus the structure of a slide fastener chain manufacturing machine can be simple and hence the rate of production is improved.Type: GrantFiled: November 24, 1997Date of Patent: September 15, 1998Assignee: YKK CorporationInventors: Hideo Shimai, Osamu Fujii, Toyoo Morita, Kazuki Kuse

Patent number: 4348164Abstract: A continuous production process for making a slab of polyurethane foam comprises preparing a foamable polyurethane composition, continuously feeding the composition to a horizontally moving trough to form a foaming mass on the trough, continuously pressing the top surface of the foaming mass with a pressure means over a zone including a zone extending from the foaming completion point to a point just prior to the completion of curing so as to make flat the top surface of the foaming mass, and horizontally moving the pressure means in synchronism with and in the same direction as the trough. Preferably, the composition is fed to the trough at such a rate as to produce a slab about 40 mm to 250 mm thick. The process can produce at a low cost polyurethane foam slabs which have no cavities and no cracks and which therefore have a uniform density or porosity.Type: GrantFiled: December 4, 1980Date of Patent: September 7, 1982Assignee: Toyo Rubber Chemical Industrial CorporationInventors: Osamu Fujii, Toshio Kishimoto, Hisao Kosuge, Ryoji Nagamine
