Title: Semiconductor switch device for circuit breaker
Inventor: YAMAMOTO MASANORI
IPC: H01H73/18
Filed: 1991-11-20
Abstract: PURPOSE:To increase a breaking capacity by connecting semiconductor connected in series with a circuit breaker to a current limiter, and putting on/off a semiconductor switch corresponding to opening/closure of the circuit breaker. CONSTITUTION:A serial circuit of a semiconductor switch 2 and a current limiter 3 is connected in parallel with a circuit breaker 1. When the circuit breaker 1 breaks the circuit for an accident, the circuit breaker 1 first starts opening action, and the semiconductor switch 2 is then controlled to be put off. Part of a current is distributed to the switch 2 corresponding to the size of an arc voltage generated by the opening action of the circuit breaker 1 at this time. A current supplied in opening of the circuit breaker 1 is thus reduced to enable breaking, so a breaking capacity is increased. The current distributed to the switch 2 is restricted by the current limiter 3, and after the breaker 1 is opened, off-control is performed by the switch 2, and the switch 2 is put off after the completion of breaking.

Title: Mounting structure for radiator
Inventor: MATSUBARA TOSHIRO
IPC: B60K11/04
Filed: 1993-12-27
Abstract: PURPOSE:To provide mounting structure for a radiator which absorbs heat distortion and can be mounted within a space having a small vertical space. CONSTITUTION:Pin projections 16, 17 formed in an upper tank 1 or a lower tank 15 of a radiator 20 are inserted into inserted holes 28 of rubber mounts 21, 22. To groove parts 27 of the rubber mounts 21, 22 U-shaped grooves 30b of a bracket 30 are respectively fitted. The bracket 30 is tightened to a vehicle member 35 by bolts 31, 32. A difference between longitudinal distortion of a tube 10 of a core part and longitudinal distortion of the vehicle member 35 is absorbed by the rubber mounts 21, 22. It is thus possible to prevent generation of breakage, leakage of water, etc., of the radiator 20 which result from heat distortion due to a difference such as material properties, temperature distribution, etc., of the radiator and attaching member; vibration of the vehicle; etc. Furthermore, the radiator can be fixed to the vehicle member 35 while securing a small space above and below the tanks 1, 15.

Title: Treating device for endoscope
Inventor: MATSUNO KIYOTAKA
IPC: A61B1/00
Filed: 1991-12-13
Abstract: PURPOSE:To prevent peeling of an external tube which covers an internal sheath especially composing an inserting part of a treating device and mutual deviation therebetween though with a simple construction. CONSTITUTION:The outer circumference of a flexible internal sheath 5 made of a metal coil is covered with a tube 6 by an extrusion molding of a resin and the tube 6 is fixed closely on the outer circumference of the internal sheath 5. In this manner since the tube 6 is fixed closely on the outer circumference of the internal sheath 5 by the extrusion molding of a synthetic resin, a closely fixing strength therebetween increases. This can prevent easy peeling of the fixed part between the both parts otherwise caused by a tension which will work on the external tube 6 during the use, heat during a high frequency energization and the like and exposure of the metal internal sheath 5 because of a deviation between both the parts.

Abstract: PURPOSE:To accurately detect the quantity of light and to provide an AC oscillator responding to the light by employing a thin film formed of metal alloy superconducting material as a Josephson element, and employing a thin film formed of an oxide superconducting material as a superconducting photodetector. CONSTITUTION:When a constant current I of Tc (superconducting transition temperature) or less of an oxide superconducting material thin film of a photodetector 1 is fed (0<I1<Ic), a voltage V is generated, with a light radiated, at a thin film detector. When a Josephson element 2 is connected in parallel with the thin film via copper wirings 3 by silver paste, soldering, etc., the element directly senses a voltage Vac across the junction to generate an AC current. An oxide superconducting material is employed as the material of the photodetector. In this case, S (sensing amount) is known to be proportional to N (number of crystalline grain boundaries). The material of the Josephson element may be selected from metal or alloy material according to the operating temperature of the element. It is easy to form the Josephson junction to use the metal or alloy material having long coherent length.
