Publication number: 20120231615Abstract: Substrates are mounted on a plurality of susceptors respectively. The plurality of susceptors on which respective substrates are mounted are placed on a rotational mechanism so that the susceptors are vertically spaced at a predetermined interval. The rotational mechanism on which the plurality of susceptors are placed is rotated. The plurality of susceptors on which the substrates are mounted respectively are heated. Semiconductor thin-films are deposited by supplying a source gas to each of the susceptors that are heated while being rotated, the source gas having been heated while passing through gas flow paths of respective path lengths substantially equal to each other.Type: ApplicationFiled: February 25, 2011Publication date: September 13, 2012Applicant: Sumitomo Electric Industries, Ltd.Inventors: Hiromu Shiomi, Yasuhiko Senda, Satomi Itoh, Kazuhiro Fujikawa, Shigeki Shimada, Jun Genba, Takemi Terao, Masaru Furusho

Patent number: 7597066Abstract: There is provided a circulation type hot water supply device in which a downstream end of a hot water delivering channel 6 connected to a heat exchanger 4 of a water heater 1 is connected to a water supply channel 5 upstream of the heat exchanger, and a circulating pump 25 that returns hot water fed from the heat exchanger to the hot water delivering channel to the heat exchanger through the water supply channel is provided in the hot water delivering channel. The device can reliably identify an abnormality when it occurs, such as adhesion of a deposit to an inner surface of a heat absorbing pipe 4b to reduce heat exchange efficiency. A diagnosis is started when a hot water delivering tap 7 is closed and a burner 3 is subjected to combustion. In the diagnosis, supply of water to the heat exchanger 4 is first stopped to shut down the burner 3.Type: GrantFiled: March 23, 2007Date of Patent: October 6, 2009Assignee: Rinnai CorporationInventors: Shigeki Shimada, Masakazu Ando

Patent number: 7467956Abstract: A plurality of terminal fittings 11 are mounted to a housing 20, board connecting portions 13 having mounting portions 14 at lower ends protrude rearward, fixed fittings 30 having mounting plates 32 at lower edges are mounted to opposite side surfaces of the housing 20, and the mounting portion 14 of each terminal fitting 11 and the mounting plates 32 of the fixed fittings 30 are secured to a PCB 40 by reflow soldering. During the reflow soldering, a drawing force toward the PCB 40 acts on each of the terminal fittings 11 and the fixed fittings 30 based on surface tension of molten solder H, but the center of the fixed fitting 30 in the fore/aft direction of the board connecting portion 13 is positioned forward of the center of gravity position O of a connector 10, and rotation moment Mb toward the PCB 40 acts on the front of the housing 20 based on a drawing force Fb on the side of the fixed fitting 30 to prevent the front from being raised.Type: GrantFiled: September 27, 2005Date of Patent: December 23, 2008Assignees: Autonetworks Technologies, Ltd., Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries, Ltd.Inventors: Hiroki Hirai, Kenji Okamura, Masahide Hio, Tetsuya Aihara, Hiroshi Nakano, Shigeki Shimada

Patent number: 7078921Abstract: A contact probe comprises a tip portion for making contact with a subject surface, a supporting portion, and a spring portion for connecting the other two members. The tip portion has a corner portion whose radius of curvature is larger than that of the opposite corner portion that moves in the lead during the scrubbing by the pressing force. The insulating layer on the subject surface is sufficiently removed by the scrubbing to secure the electrical contact, and the amount of shavings is minimized during the dissociation of the contact probe. Formation of scratches on the subject surface is reduced. Another contact probe for a ball-shaped electrode has a tip portion with a recess, which has a protrusion and bottom. The protrusion breaks the insulating layer on the electrode to secure the electrical contact. The bottom makes contact with the electrode to prevent the protrusion from excessively biting the electrode.Type: GrantFiled: October 10, 2002Date of Patent: July 18, 2006Assignee: Sumitomo Electric Industries, Ltd.Inventors: Tsuyoshi Haga, Shigeki Shimada, Atsushi Kimura
