Title: Sintered oil-containing bearing for small fan
Inventor: SEKIMOTO TETSUO
IPC: B24B39/02
Filed: 1991-05-07
Abstract: PURPOSE:To eliminate noises caused by a bearing and reduce noises of a small fan by forming a bearing hole which has a specified diameter as a polished- surface prepared by a rotational sizing pin made of tungsten carbide base hard alloy whose sizing surface has a specified surface roughness. CONSTITUTION:A sintered oil containing bearing for a small fan is prepared by inserting a sizing pin into a bearing hole of a bearing material for sizing. Oil impregnation is performed on an oilless one. A diameter of the bearing hole is ranged between 0.5 and 5mm. The bearing hole is formed as a polished surface by means of the rotational sizing pin 1 which is made of tungsten carbide base hard alloy having a sizing surface 1a provided with surface roughness of 0.1 to 1S. The sizing pin 1 is installed on a holding part 2, while cutouts 1b are formed on the sizing surface 1a along the longitudinal direction with equal intervals. Noises caused by a bearing surface are eliminated, and thereby noises of the small fan are reduced.

Title: Switching regulator circuit
Inventor: IWABUCHI SHIYUNJI
IPC: H02M3/28
Filed: 1979-10-15
Abstract: PURPOSE:To alleviate the loss of a switching transistor by employing a thyristor for a control unit. CONSTITUTION:A sawtooth voltage is applied from an integrating circuit having a resistor 8 and a capacitor 9 connected across a feedback winding 6 to the gate of a thyristor 7 in the state that a switching transistor 1 is sufficiently saturated, a base current is flowed to the thyristor 7 upon conduction of the thyristor 7, charged voltage of the capacitor 3 is simultaneously applied between the base and the emitter of the transistor 1, thereby flowing a reverse base current so as to break the transistor 1 forcibly thereby. Since the enable state of the transistor 1 can be shortened in operating duration in this manner, it can be sufficiently saturated until the transistor 1 is broken. Since reverse base current can be flowed largely, the falling time can be improved so as to alleviate the switching loss of the transistor.

Title: Plate frame for wiring instrument
Inventor: KATO SHIGENORI
IPC: H02G3/02
Filed: 1989-05-25
Abstract: PURPOSE:To house a plate frame into a burying box by installing a first deflection stopping section to the central piece of a plate frame body and narrowing size between deflection engaging sections projected to a section rearer than the plate frame body. CONSTITUTION:An engaging hole 34 into which the engaging piece 5 of a receptacle 3 is inserted and retained is formed to the other side piece of a plate frame body 1. A first engaging section 41 is composed of the engaging hole 34, and a first deflection engaging section 42 consists of a flexible rib 32, an engaging hole 33, etc. Since only the engaging hole 34 may be formed in the first engaging section 41 and the engaging section 41 has no defection section at that time, the size of a protruding section 35 and a flexible piece 11 projected to a rear and the inside can be reduced, thus bringing the bulge size of the rear of the plate frame body 1 to the size fitted for a burying box.

Title: Field effect type semiconductor sensor
Inventor: NISHIGUCHI KATSUNORI
IPC: G01N27/00
Filed: 1984-06-27
Abstract: PURPOSE:To easily protect the gate part of a transistor TR and to prevent a conductive material layer which connects a gate oxide film and a chemically sensitive layer from varying in potential owing to disturbance by forming the gate part and chemically sensitive part spatially at distance from each other. CONSTITUTION:The gate part of the TR and chemically sensitive part 7 are formed at distant positions which are successive in the same plane or spatially to easily protect the gate part. The greatest effect is that measurement is taken where a normal sensor can not perform stable measuring operation, for example, in an objective measurement atmosphere in which the movement of charges such as ions is violent because the sensor becomes very tolerant to electric disturbance. The gate part structure and chemically sensitive part 7 are separated from each other by using the conductive material layer 9 to improve the stability, prolong the life, and take a stable measurement by the sensor for a long period without spoiling a decrease in variance in characteristics among sensors.

Abstract: PURPOSE:To prevent the destruction of GTOs, when an anode current is small, by providing a period applying a turn-on DC voltage and a turn-off DC voltage at the same time at turn-off of the GTOs. CONSTITUTION:A gate circuit 12 of a GTO10 has a turn-on gate circuit 12a and a turn-off gate circuit 12b connected between the gate and cathode and the GTO is turned on by a switch control signal A applied to a switch 16 of the gate circuit 12a.

Abstract: PURPOSE:To reduce the size of an electrolytic plate required for generating the same output while suppressing generation of a warp thus improving cell performance, efficiency and sealing performance, reliability and safety by dividing an electrolytic plate into a part of the electrolytic plate participating in electrochemical reaction and a sealing part. CONSTITUTION:An electrolytic plate 5 is divided into the electrochemical reaction pat 19 and the manifold sealing part 20 while the manifold sealing part 20 is provided with holes 11.
