Patent number: 7138435Abstract: A method of decomposing a thermosetting resin by a decomposer comprising the steps of: pre-heating the thermosetting resin up to a pre-heating temperature T0; kneading the pre-heated thermosetting resin together with a decomposer, and concurrently heating a mixture comprising the thermosetting resin and the decomposer up to a kneading temperature T1, thereby allowing a reaction to take place between the decomposer and the thermosetting resin to obtain a kneaded matter wherein the decomposer becomes consumed; and heating the kneaded matter to a maximum temperature T2 to thereby decompose the thermosetting resin; wherein the preheating temperature T0 is not higher than the boiling temperature of the decomposer; the kneading temperature T1 is not lower than the pre-heating temperature T0 but is lower than the thermal decomposition temperature of the thermosetting resin; the maximum temperature T2 is lower than the decomposition temperature of the thermosetting resin; and the pre-heating of the thermosetting resiType: GrantFiled: September 28, 2001Date of Patent: November 21, 2006Assignee: Kabushiki Kaisha ToshibaInventors: Yumiko Oyasato, Cao Minh Thai, Shioko Saya, Shinetsu Fujieda, Tomiaki Furuya

Patent number: 6464122Abstract: Disclosed is a method and an apparatus for soldering a base material. A binary solder essentially consisting of tin and a metal which can form an eutectic alloy with tin and which is exclusive of lead is prepared. The content of other metallic components is 0.1% by weight or less and the content of oxygen is 100 ppm or less. The binary solder is melted in a non-oxidizing environment and dispensed to the base material in an atmosphere in which the oxygen content is 2,000 ppm or less, to solder the base material with the binary solder. The soldering apparatus comprises an oscillator for supplying oscillatory wave energy having frequency of 15 KHz to 1 MHz to the base material. The soldering apparatus can also be realized in the form of a soldering nozzle or a soldering iron.Type: GrantFiled: August 25, 2000Date of Patent: October 15, 2002Assignees: Kuroda Techno Co., Ltd., Kabushiki Kaisha ToshibaInventors: Masahiro Tadauchi, Makoto Gonda, Yoshiyuki Goto, Tomiaki Furuya, Kouichi Teshima, Izuru Komatsu, Takeshi Gotanda

Patent number: 5577906Abstract: A combustion catalyst is disclosed which is composed of a durable support containing a plurality of mutually partitioned and independent combustion gas flow paths and an active catalyst formed mainly of palladium and/or palladium oxide and deposited in the form of a coating on the inner wall surfaces of the combustion gas flow paths and characterized in that the deposition of the active catalyst in the form of a coating on all the inner wall surfaces is omitted in part of the whole of the combustion gas flow paths. The mutually partitioned and independent combustion gas flow paths which are provided for the durable support jointly form an aggregate of opening parts in the pattern of gratings and these opening parts have a square, rectangular, triangular, or hexagonal cross section. Thus, the durable support constitutes a so-called honeycomb structure.Type: GrantFiled: December 21, 1994Date of Patent: November 26, 1996Assignee: Kabushiki Kaisha ToshibaInventors: Yoshio Hanakata, Tomiaki Furuya

Patent number: 5000004Abstract: A gas trubine combustor includes a main body with a combustion portion into which mixture of fuel and air is supplied. The gas mixture is burned through a catalytic reaction at a catalyst body arranged in the main body. The gas mixture passed through the catalyst body is introduced into a gas phase combustion portion provided in the main body. Between the catalyst body and the gas phase combustion portion is arranged a dividing unit which has a plurality of branch passages. The gas mixture passed through the catalyst body is divided by the dividing unit into a plurality of gas streams flowing through the branch passages. Each of the gas streams is mixed with fuel supplied from a fuel supply tube.Type: GrantFiled: August 9, 1989Date of Patent: March 19, 1991Assignees: Kabushiki Kaisha Toshiba, The Tokyo Electric Power Co., Inc.Inventors: Susumu Yamanaka, Tomiaki Furuya, Terunobu Hayata, Junji Koezuka, Katsuhei Tanemura, Akio Ohkoshi, Yukiyoshi Hara, Hitoshi Tominaga, Susumu Handa
