Patent number: 7297955Abstract: Each semiconductor radiation detector used for a nuclear medicine diagnostic apparatus (PET apparatus) is constructed with an anode electrode A facing a cathode electrode C sandwiching a CdTe semiconductor member S which generates charge through interaction with ?-rays. Then, a thickness t of the semiconductor member S sandwiched between these mutually facing anode electrode A and cathode electrode C is set to 0.2 to 2 mm. Furthermore, the devices are mounted (laid out) on substrates in such a way that the distance (distance of conductor) between the semiconductor radiation detector and an analog ASIC which processes the signal detected by this detector is shortened. Furthermore, the substrates on which the detectors are mounted are housed in a housing as a unit (detector unit).Type: GrantFiled: June 24, 2004Date of Patent: November 20, 2007Assignee: Hitachi, Ltd.Inventors: Kensuke Amemiya, Yuuichirou Ueno, Hiroshi Kitaguchi, Osamu Yokomizo, Shinichi Kojima, Katsutoshi Tsuchiya, Norihito Yanagita, Kazuma Yokoi

Patent number: 7278255Abstract: Disclosed is a gas turbine power generating system capable of achieving a high output power and a high power generating efficiency under conditions with a small amount of supplied water and less change in design of a gas turbine. A fine water droplet spraying apparatus (11) is disposed in a suction air chamber (22) on the upstream side of an air compressor (2), and a moisture adding apparatus (7) for adding moisture to high pressure air supplied from the compressor (2) is disposed. A regenerator (5) for heating the air to which moisture has been added by using gas turbine exhaust gas as a heat source is also provided. With this configuration, there can be obtain an effect of reducing a power for the compressor (2) and an effect of increasing the output power due to addition of moisture to air (20) for combustion. Further, since the used amount of fuel is reduced by adopting a regenerating cycle, the power generating efficiency is improved.Type: GrantFiled: August 15, 2006Date of Patent: October 9, 2007Assignee: Hitachi, Ltd.Inventors: Shigeo Hatamiya, Masahiko Yamagishi, Osamu Yokomizo, Yoshiki Noguchi, Moriaki Tsukamoto

Patent number: 7091625Abstract: During a time zone where a power demand is smaller than an average value of the entire power demands of homes, an excess portion obtained by subtracting a power demand from a base power portion supplied by PEFC (1) is charged in a capacitor (7) and a lead storage battery (8) in advance; and during a time zone where a power demand is larger than the average value, a peak power portion exceeding this average value is discharged from the capacitor (7) and the lead storage battery (8); thereby enabling the system to sufficiently meet daily home-use demand with requisite minimum equipment while effectively using surplus power. Thus, energy efficiency can be enhanced without wasting energy, and also cost efficiency can be improved.Type: GrantFiled: April 7, 2004Date of Patent: August 15, 2006Assignee: Hitachi, Ltd.Inventors: Tsutomu Okusawa, Osamu Yokomizo, Toshiki Kahara, Kouichi Chino, Takaaki Mizukami, Shin Takahashi
