Title: Production of oxide superconductor
Inventor: UCHIUMI KAZUAKI
IPC: H01B12/00
Filed: 1987-05-29
Abstract: PURPOSE:To enable change of a sintered material having lost superconductive characteristics into structure showing superconductivity in a production of a copper-containing oxide superconductor, by chemically oxidizing the sintered material with an aqueous solution of hydrogen peroxide. CONSTITUTION:For example, BaCO3, Y2O3 and CuO having >=99.9wt.% are used as starting raw materials and these materials are each weighed to give the blending ratio of Ba2YCu3O7. The these weighed materials are blended in a ball mill in a wet state and fired at about 850-950 deg.C. The powder if ground by a mortar, mixed with an organic binder, finely granulated and pressed to form a disc of desired dimension. Then the disc is sintered in O2 at about 950-1,050 deg.C for about 4hr and annealed in N2 at about 700 deg.C for about 2hr. Further the specimen is immersed in 30% aqueous solution of hydrogen peroxide at room temperature for about 2hr and dried. By this method, the copper ion changed from trivalent to divalent ion by the reduction in the oxide superconductor can be reoxidized into a trivalent ion. Consequently, a sintered material not showing superconductivity can be changed into structure showing superconductivity without high-temperature treatment.

Title: Trouble diagnosing device for exhaust gas circulation device
Inventor: MAEDA MIE
IPC: F02D45/00
Filed: 1991-06-10
Abstract: PURPOSE:To detect the change of the operation state in a simple manner by carrying out the correct trouble diagnosis on the basis of the difference in each parameter between the transition from the opening to closing of an exhaust gas circulation passage and the transition from the closing to opening, and the judgement of the change of the engine operation state. CONSTITUTION:A circulation valve 11 is arranged in an exhaust gas circulation passage which connects the intake pipe 3 and the exhaust pipe 15 of an engine 1. An electronic type control unit 22 controls the circulation valve 11 on the basis of a variety of detection signals supplied from a pressure sensor 6 for detecting the operation state of the engine 1, throttle opening degree sensor 8, etc. In this case, the electronic type control unit 22 calculates the difference of the variation quantity of each parameter between the transition from the opening to closing of the exhaust gas circulation passage and the transition from the closing to opening, and judges the change of the operation state by comparing the calculation value with a prescribed value. Accordingly, when the operation state changes, the trouble diagnosis is prohibited. While, if the operation state is not changed, the variation quantity of each parameter is compared with the second prescribed value, and trouble diagnosis is carried out.

Title: Bent double exhausting device and its manufacture
Inventor: NORIKAWA TANOMO
IPC: F01N13/08
Filed: 1994-06-20
Abstract: PURPOSE:To simplify a construction and enable the assembly of the construction by holding a spacer between the one end of a bent inner tube and the one end of a bent outer tube. CONSTITUTION:A spacer 10 is positioned between a pair of bulged parts 5 and 6 of a bent inner tube 1, and held between the outer surface of the bent inner tube 1 and the inner surface of a bent outer tube 3. The one end 4 of the bent inner tube 1 is therefore connected to the one end 7 of the bent outer tube 3 so that they can be moved in axial direction relatively to each other through the spacer 10. By this, the one end 4 of the bent inner tube 1 is free over the spacer 10, and thus the one end 4 of the bent inner tube 1 can be heat-deformed along its axial direction by exhaust gas. Then, because the spacer 10 is held between the pair of bulged parts 5 and 6 of the bent inner tube 1, a displacement caused at the one end 4 of the bent inner tube 1 provides the same function as the spacer 10 is fixed to the one end 4 of the bent inner tube 1. Thus the construction of a sliding part at the one end of the bent inner tube 1 and bent outer tube 3 can be simplified.

Title: Load-measuring apparatus
Inventor: HAMA KAZUAKI
IPC: G01G3/14
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To obtain a thin measuring apparatus having a high measurement accuracy, by setting a strain-detecting means for detecting a strain in a longitudinal direction of a load cell and a frame body having a projecting part for supporting the strain-generating body from the opposite side to a load stage, and constituting a supporting member of an elastic body. SOLUTION: A load cell 3 has uniaxial type strain gages 4 attached to the center in a longitudinal direction of an upper and a lower faces of a long body. A reference line of the strain gages 4 agrees with the longitudinal direction of the load cell 3. When a distributed load by an object to be measured acts to a top plate 1, the load is transmitted from two load points 2 to the load cell 3. The load points 2 are constituted of an elastic body. The load cell 3 and top plate 1 are freely supported via the elastic bodies. A size of a moment acting to the load cell 3 becomes a constant value determined by a load irrespective of a contact area of a load face where the object is placed. A stable load output can be obtained by placing the object so that the center of gravity is positioned to the center of the top plate 1.
