Title: Heat treatment of gear shaft
Inventor: OOSAKA YASUNOSHIN
IPC: C21D1/10
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To execute the heat treatment of quenching and tempering, etc., under condition of uniformly holding the temp. distribution at each part of a gear shaft part by executing the heat treatment while separating gear parts of gear shafts and the gear shaft parts, and a shaft part and a spline part. SOLUTION: In the case of executing the heat treatment of the gear shaft 1, the temp. in the heat treatment is uniformized while adjusting heating power with the frequency having little effect of a coil gap and to the frequency heated from the tooth bottom to the portion faced to the gear part 2 and the portion faced to the gear shaft parts 3, 4 in a multi-winding coil 7 for stationary quenching. Since the shaft part 5 and the spline part 6 have almost the equal diameter, and the tip part of the spline part 6 forms free-state, the heat treatment is executed by using a coil 8 for movably quenching. During quenching the gear parts and the gear shaft parts 3, 4, the coil 8 for movably quenching is slowly moved while supplying the pre-calculated power to the coil 8 to execute the quenching while moving.

Title: Base isolation foundation of tank
Inventor: ISHIDA KAZUO
IPC: B65D90/22
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To realize a sufficient long period applicable to a large-sized tank by providing a support plate facing a bottom plate of a tank supported by a column and putting a laminated rubber between the support plate and the tank bottom plate. SOLUTION: A base siolation foundation comprises a tank 1 placed on the ground which is supported by a column 2 via a laminated rubber 3, a support plate 5 facing a bottom plate 1a of the tank 1 provided on the column 2, and the laminated rubber 3 interposed between the support plate 5 and the bottom plate 1a of the tank 1. Thus a diameter size of the laminated rubber 3 is not limited by a diameter size of the column 2, and a natural period of the tank 1 can be sufficiently lengthened. In addition, the number of installed laminated rubbers 3 can be less than that of the columns 2. Using a laminated rubber 3 with a large diameter naturally reduces the number of installed rubbers, so that a load applied to a single rubber 3 naturally increases, resulting in advantage in lengthening the period.

Title: Exhaust gas recirculating device for engine with turbocharger
Inventor: NANRI TAKASHI
IPC: F02B37/24
Filed: 1993-12-17
Abstract: PURPOSE:To attain recirculation of exhaust gas by an amount which is considered optimum, in various operating conditions of an engine. CONSTITUTION:A variable displacement turbocharger 81 is used as the turbocharger, and exhaust gas, taken out from an inlet side of this turbine 71, is recirculated through an exhaust gas recirculating pipe 13. In an exhaust pressure in the turbine inlet side, since an opening of a movable nozzle of the variable displacement turbocharger can be controlled by a step motor 23, a relation of exhaust pressure> boost pressure for enabling exhaust gas to recirculate can be easily obtained. A recirculating amount control valve 20 in the exhaust gas recirculating pipe 13 controls a recirculated exhaust gas amount so as to obtain an suitable value without worsening combustion of an engine. An exhaust pressure and boost pressure, in the case of excessive rising thereof to a hazardous degree, are decreased by opening an exhaust waste valve 21 in an exhaust waste pipe 22.

Filed: 1989-12-28
Abstract: PURPOSE: To provide a control circuit whose operation is easy, whose reliability is high and cost effect is high by controlling the state of a switch through the magnetic connection of transformer coils of a control transformer. CONSTITUTION: The switch 24 connected to the control transformer 12 is provided by using the control transformer having the plural coils.
