Patent number: 7086739Abstract: A time management section is configured to change an output voltage in accordance with a temperature change characteristic of a lamp allowed to cool down. For restart of the lamp after the turn-off of the lamp, the lamp is cooled by a fan before the operation of turning on the lamp when it is judged that the temperature of the lamp is higher than a predetermined value, based on the output voltage from the time management section. The lamp is immediately turned on without the cooling of the lamp by the fan when it is judged that the temperature of the lamp is lower than the predetermined value.Type: GrantFiled: April 21, 2004Date of Patent: August 8, 2006Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Hiroshi Kida, Naoto Kontani, Tomohiro Bessho, Mitsuhiro Kawaguchi

Patent number: 6709112Abstract: It is an object to obtain a light source device and a projection type display device in which a fragment can be completely enclosed therein even if a discharge lamp bursts during lighting. During normal lighting of a discharge lamp (1), an internal space of a light source device (10) and an external space are spatially connected to each other through a vent hole (43) formed on a cutoff valve mechanism (45) and a vent hole (100) formed on a concave reflecting mirror (4). Cooling air is introduced and discharged between the internal space and the external space so that the discharge lamp (1) is cooled down. When the discharge lamp (1) bursts during lighting for some reason, a very strong impulsive pressure wave is generated in a moment of the burst. The pressure wave presses a movable valve (41) provided in the cutoff valve mechanism (45) through the vent hole (100).Type: GrantFiled: October 11, 2002Date of Patent: March 23, 2004Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Teruo Miyamoto, Hideharu Tanaka, Mitsuhiro Kawaguchi, Tatsuro Hirose, Toshimitsu Iwai, Tomohiro Bessho

Patent number: 4759663Abstract: A method of placing concrete into a steel encasement constructing an offshore structure. The steel encasement is erected. A plurality of first concrete injection holes are formed through the steel encasement in a heightwise spaced manner. The concrete is injected through the lowest disposed concrete injection hole into the erected steel encasement to a level below another concrete injection hole disposed just above said lowest disposed concrete injection hole. Then, the injection step is repeated in connection with a subsequent first concrete injection hole nearest to the level, to which the concrete has been placed, for placing the concrete into the steel encasement to a predetermined level.Type: GrantFiled: November 19, 1986Date of Patent: July 26, 1988Assignees: Nippon Kokan K.K., Shimizu Construction Co., Ltd.Inventors: Hideo Watanabe, Tomoo Suzuki, Takayoshi Ota, Gaku Matsumoto, Tomohiro Bessho, Tamiki Koyama, Katuhiko Kimura, Yasuo Kajioka, Minoru Imai
