Patent JP-H08222089-A (JP)
Title: Vacuum bulb
Inventor: NAKAMURA SEIICHI
IPC: H01H33/66
Filed: 1995-02-10
Abstract: PURPOSE: To enhance the carrying-current without enlarging the outer form by forming at least one of a fixed electrode and a movable electrode by impregnating a highly conductive part consisting of a highly conductive material with a material lower in conductivity than it. CONSTITUTION: At least one of a fixed electrode and a movable electrode is formed by impregnating a highly conductive coil electrode with a material slightly lower in conductivity than it. Namely, an impregnated part 1b impregnated with the material slightly lower in conductivity than a highly conductive part 1a is formed between a current-carrying shaft 4 and a contact 2. The part 1a is, for example, formed of copper, and an alloy lower in conductivity than copper such as silver-copper alloy is impregnated in the space part, whereby an electrode 1 is formed. At current-carrying, a large current can be carried since the current is carried to the whole electrode, while the large current can be interrupted with a small electrode at interruption since the interrupting performance is enhanced by forming a longitudinal magnetic field or vertical magnetic field.

Title: Material for insulating resin coating electrical contact and manufacture thereof
Inventor: SUZUKI SATOSHI
IPC: H01H1/04
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent contamination on a contact part due to creeping sulfide by coating a non-electrical contact part including the periphery of an electrical contact part coated with layers of one kind of Au, Ag, Pd, Rh, Ru, Pt, Ni and Sn or the alloy thereof on a conductive band material with a specified film thickness of the insulating resin. SOLUTION: A non-electrical contact part is coated with the insulating resin such as the soft and easy workable epoxy resin and the urethane resin at 5-100 μm of thickness so as to prevent cracking in a pin hole and a plate spring or the like during work. Especially, generation and growth of the creeping sulfide at positions except for the electrical contact part to be cleaned by the opening and closing operation can be prevented by a layer of Ag and Cu. High adhesive strength can be obtained by a method of coating the solvent solution of the insulating resin with a brush or a spray and for drying and curing it with the radiation of the ultraviolet rays.  Manufacturing efficiency is improved by a method of coating the whole of one surface of the wide-width conductive band material with electrical plating of the layered metal at a low cost, and coating the other surface with the insulating resin, and cutting the conductive band material.

Title: Thin film transistor
Inventor: MATSUNO AKIRA
IPC: H01L27/12
Filed: 1986-02-05
Abstract: PURPOSE:To make an ON/OFF ratio sufficiently large even at the time of light irradiation by composing a gate insulating film out of an insulating layer consisting of a substance of small light transmittivity. CONSTITUTION:This device is composed of a gate electrode consisting of a pattern of chromium thin film formed on a light-transmitting glass substrate 1, a gate insulating film 3 consisting of a black tantalum oxide layer and a semiconductor active layer 4 consisting of an amorphous silicon I layer which are laminated on said gate electrode 2 in order, and a source electrode 5 and a drain electrode further formed with an interval on the substrate. If light enters from the substrate side, the tantalum oxide film prevents the light from entering into the semiconductor layer and no photocurrent is produced. Thus, as the gate insulating film intercepts the light so as to prevent photoconductive effect in the semiconductor layer, an ON/OFF ratio at the time of light irradiation can be improved.

Title: Rotary mirror optical deflector
Inventor: KATO SHIGEO
IPC: H02K7/09
Filed: 1988-02-05
Abstract: PURPOSE:To enable extremely fast rotation by supporting a rotary shaft to which a rotary mirror is added by a journal bearing consisting of a dynamic air bearing supported by an elastic body or/and a viscoelastic body. CONSTITUTION:The rotor 13 of a motor and the rotary magnet 4 of a magnetic bearing are fitted to the rotary shaft 12 fitted with the rotary mirror 11. The rotary shaft 12 is supported by one nonarc type dynamic pressure air type journal bearing 18 each above and below, i.e. two bearings in total, and further received by several elastic bodies 19 such as springs connected to a casing 15. The viscous body 20 such as oil and grease is put between the casing 15 and journal bearing 18, so the vibration energy of the rotary shaft is eliminated here. Consequently, the rotary shaft never contacts the bearing even in case of large vibration at a resonance point and the extremely fast rotary mirror optical deflector is obtained.

Filed: 1995-02-13
Abstract: PURPOSE: To reduce noise and air flowing resistance, to make small an indoor device and to improve its capability by a method wherein a heat generating heater is fixed to a fan shaft part of a blower or an axial flow fan hub part. CONSTITUTION: When an axial flow fan 18 is rotated in an arrow direction W, air W sucked from a suction port 12 passes through an inner part of a wind tunnel 15 and is discharged out of a blowing port 13. At this time, the air W heat exchanged and heated by a heat exchanger 17 within the wind tunnel 15 is further heated by a heat generating fan 19 fixed to a shaft portion of the axial flow fan 18 and then this air is discharged out of the blowing port 13. Thus, the heat generating heater 19 fixed to the shaft part of the axial flow fan 18 becomes a quite compact indoor machine configuration not influencing against an air blowing characteristic and an increased noise due to the fact that the air is heated while being taken under an action of the axial flow fan 18.
