Publication number: 20020020224Abstract: There is a difficulty in workability of installing an optical fiber cable on a concrete structure, and when the optical fiber cable is installed on the surface of the concrete structure, the appearance of the concrete structure is spoilt by cutting the surface of the concrete structure or the like. Accordingly, there are provided a sheet-like strain sensor for confirming progress of damage of a concrete structure, in which one or a plurality of optical fiber cables are fixedly held between sheet-like bodies which are easy for the adhesive to permeate while one end/ends of the optical fiber cable/cables are pulled out; and a method for confirming progress of damage of a concrete structure by measuring strain by use of the one end of the optical fiber cable pulled out between the sheet-like bodies.Type: ApplicationFiled: April 30, 2001Publication date: February 21, 2002Applicant: SHO-BOND CORPORATIONInventors: Takashi Sato, Katsumi Hino, Kazuo Eguchi, Tatsuro Yoshinaga

Patent number: 5728253Abstract: Disclosed herein is a method of detecting an end point of plasma process performed on an object, and a plasma process apparatus. The method includes the steps of detecting an emission spectrum over a wavelength region specific to C.sub.2 in the plasma, by optical detecting means, and determining the end point of the plasma process from the emission intensity of the emission spectrum detected by the optical detector. The apparatus has a process chamber, a pair of electrodes, a light-collecting device, an optical detector, and a determining device. The chamber has a monitor window. The electrodes are located in the process chamber. The first electrode is used to support the object. A high-frequency power is supplied between the electrodes to change a process gas into plasma. The light-collecting device collects the light from the plasma through the monitor window. The optical detector detects an emission spectrum from the light collected.Type: GrantFiled: September 30, 1994Date of Patent: March 17, 1998Assignees: Tokyo Electron Limited, Tokyo Electron Yamanashi LimitedInventors: Susumu Saito, Kazuo Eguchi

Patent number: 5717294Abstract: A vacuum chamber contains a first electrode for supporting a wafer, and a second electrode opposing the first electrode. A supply system and an exhaustion system are connected to the vacuum chamber. The system supplies a reactive gas into the chamber, and the system exhaust the used gas from the chamber. A radio-frequency power supply is connected to the first electrode, for supplying power between the electrodes to generate an electric field E. An annular magnet assembly is provided around the chamber, for generating a magnetic field B which has a central plane intersecting with the electric field E. The magnet assembly has a plurality of magnet elements which have different magnetization axes in the central plane of the magnetic field. Electrons drift due to a force resulting from an outer product (E.times.B) of the electric field E and the magnetic field B.Type: GrantFiled: February 27, 1995Date of Patent: February 10, 1998Assignees: Kabushiki Kaisha Toshiba, Tokyo Electron Limited, Tokyo Electron Yamanashi LimitedInventors: Itsuko Sakai, Makoto Sekine, Keiji Horioka, Yukimasa Yoshida, Koichiro Inazawa, Masahiro Ogasawara, Yoshio Ishikawa, Kazuo Eguchi

Patent number: 4343960Abstract: An improved thermopile is provided. A plurality of thermocouples constituting the thermopile are composed of segments of one metal and segments of the other metal, and the segments of different metals are connected to one another alternately so that the thermocouples are arranged in series on a heat-resistant, electrically non-conductive substrate. Each segment has a portion plated on one surface of the substrate, a portion plated on the other surface of the substrate and a portion plated on the inner wall of through holes formed in the substrate to connect the two portions plated on the two surfaces of the substrate with each other. The thermopile is prepared advantageously by utilizing plating and photo-etching techniques.Type: GrantFiled: November 12, 1980Date of Patent: August 10, 1982Assignees: Building Research Institute, Ministry of Construction, Ryoko Electronic Industries Ltd., Eko Instruments Trading Co., Ltd.Inventors: Kazuo Eguchi, Tadashi Kobayashi, Yukiharu Miyake

Patent number: 4181211Abstract: In a pallet exchange apparatus for a machine tool, a rotary member carried to be rotatable in a horizontal plane mounts thereon a pallet support means which in turn supports a pallet unloaded from the machine tool and a pallet to be loaded into the machine tool. Each pallet is provided with an engaging hook. A transfer member is provided with a transfer hook engageable with the engaging hook to move the pallet to be loaded on the machine tool toward the machine tool. A fixed hook is provided to be engageable with the engaging hook. The rotary member is rotated to move the engaging hook of the pallet to be loaded on the machine tool into engagement with the transfer hook and to move the engaging hook of the pallet unloaded from the machine tool into engagement with the fixed hook.Type: GrantFiled: May 23, 1978Date of Patent: January 1, 1980Assignee: Toyoda-Koki Kabushiki-KaishaInventors: Hideo Nishimura, Kenji Nomura, Fumihiko Ohkoshi, Akira Tsuboi, Yoji Kamiya, Kazuo Eguchi, Kunimichi Nakashima
