Patent number: 6711017Abstract: Provided is a cooling apparatus for feeding liquid coolant to electronic elements as heat generating elements in an electronic system through a cooling pipe. The cooling pipe is in part flattened so as to form flattened portion which is made into contact with the electronic parts for cooling the latter. With this arrangement, the pipe line working is simplified while the number of joint parts in the pipe line is decreased so as to prevent leakage of the liquid coolant. Further, the heat-exchange capacity of a heat-exchanger unit is controlled in accordance with an atmospheric temperature, a temperature in the electronic system and a temperature of the liquid coolant in order to aim at preventing occurrence of freezing or dewing while enhancing the operating efficiency. Further, in an electronic apparatus having two electronic systems, a liquid coolant tank is commonly used for two electronic systems in order to prevent occurrence of dewing or freezing in a cooling system for the electronic system on resting.Type: GrantFiled: July 17, 2002Date of Patent: March 23, 2004Assignees: Hitachi Kokusai Electric Inc., Hitachi, Ltd.Inventors: Tateki Kurokawa, Akira Saito, Toshio Fukukawa, Mikio Harada, Takahiro Daikoku, Hideo Yazawa

Patent number: 5587867Abstract: A surge absorber composed of a surge absorbing element comprising a silicon two-terminal thyristor element having a PNPNP or NPNPN junction structure and a bulk resistance element 12 comprising a material having a resistivity within a range of from 10.sup.-4 .OMEGA..multidot.cm to 10.sup.3 .OMEGA..multidot.cm and having a resistance value within a range of from 5.OMEGA. to 50.OMEGA., these elements being connected in series to form an integral body is disclosed. The inventive surge absorber requires reduced manhours for its production and is of a small size, but yet provides a large surge capacity.Type: GrantFiled: June 27, 1994Date of Patent: December 24, 1996Assignee: Mitsubishi Materials CorporationInventors: Koichi Kurasawa, Mikio Harada, Takaaki Ito

Patent number: 5308392Abstract: A dry friction material comprises fiber base material, bonding agent, friction conditioner and filler. The dry friction material contains 2 to 20% by weight of a tin alloy in which the fusing point is more than 500.degree. C. and the hardness is less than 4 Moh's. The dry friction material shows excellent friction characteristics when the load is low or average.Type: GrantFiled: October 23, 1992Date of Patent: May 3, 1994Assignee: Aisin Kako Kabushiki KaishaInventors: Kazuya Morita, Teruo Matsukawa, Mikio Harada

Patent number: 4317155Abstract: A novel gap type surge absorber. The surge absorber comprises a plurality of conductive ceramic thin films formed on the surface of a molded insulating body and separated from each other by an extremely narrow gap, electrodes composed of a metallic material fixed to both ends of the plural conductive ceramic thin films and an inert gas sealed between the electrodes. The surge absorber is based on a two-stage discharge mechanism consisting of a discharge due to electrons emitted between the conductive ceramic thin films when a surge voltage is applied to the electrodes and a following creeping discharge generated between the electrodes. The surge absorber has a prolonged life and a good annealing characteristic as well as a very small discharge lag and a small electrostatic capacity and is excellent in cutting off a follow current.Type: GrantFiled: August 20, 1979Date of Patent: February 23, 1982Inventors: Mikio Harada, Kan-ichi Tachibana, Akio Uchida, Takashi Saitoh

Patent number: 4268295Abstract: Apparatus and method for manufacturing crushed sands from blast furnace melted slags including maintaining molten blast furnace melted slags out of contact with water while cooling the molten slags to a temperature between 850.degree. C. to 1300.degree. C. and then rapidly cooling the cooled slags with water thereby producing coarse grain hard quality water processed slags.Type: GrantFiled: July 6, 1979Date of Patent: May 19, 1981Assignee: Nakayama Steel Works, LimitedInventors: Katsuji Yamamoto, Yuichiro Iwasaki, Akira Adachi, Toshiro Kawata, Keisuke Nagano, Seiichi Fujita, Mikio Harada
