Abstract: PURPOSE:To provide an excellent gas-blast circuit breaker by which high arc extinguishing performance can be obtained by blowing powerful gas flow upon the arc even in the case of breaking in a small electric current and driving operational force can be reduced to less than that of a puffer-type gas circuit breaker. CONSTITUTION:Gas pressure in a compression chamber 5 composed of an insulating nozzle 4, a cylinder 3 and a bottom plate 23 is rised by using heat energy of the arc 6 generated between fixed/ movable electrodes 1 and 2, and is blown upon the arc so as to be extinguished. A through hole 25 is arranged in the bottom plate 23 of the compression chamber 5, and a guide rod 27 is arranged so as to lead to the compression chamber 5 by passing penetratingly through the through hole 25. A moving plate 26 to compress gas is arranged in the compression chamber 5. A pressing spring 29 to press the moving plate 26 is arranged on the compression side. The pressing spring 29 and the moving plate 26 are constituted so as to be movable by compressing the pressing spring by means of the movable plate according to the gas pressure in the compression chamber 5 in the case of breaking operation.

Title: Cooler
Inventor: TANIMOTO KEISUKE
IPC: F28D21/00
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To prevent cooling water from being contaminated without sacrifice of the performance of a cooler for cooling water. SOLUTION: A cooling exchanger 15 comprises a moisture permeation membrane 5 which passes steam but blocks water. The cooling exchanger 15 is disposed in the air passage 24 at a cooling tower section 20 and the cooling water is brought into contact with the air through the moisture permeation membrane 5. Since a part of cooling water is evaporated and discharged into the air through the moisture permeation membrane 5, high cooling performance can be sustained. Furthermore, cooling water can be protected against contamination because it is not mixed with gas or contaminant in the air.

Title: Truck roller bearing floating sleeve device
Inventor: ESU ROBAATO AARUMAN
IPC: F16C33/20
Filed: 1991-10-04
Abstract: PURPOSE: To eliminate early destruction due to fatigue destruction and uneven wear by providing a bearing assembly provided with a sleeve having an outer face in the radial direction and an inner face in the radial direction. CONSTITUTION: A track roller bearing has a floating sleeve 50 between an inner race 10 and an outer race 20. The floating sleeve 50 has a self-lubricating bearing material 52 on its outer surface. The coefficient of friction of the self- lubricating bearing material 52 increases as the self-lubricating material is worn. When the self-lubricating bearing material coefficient of friction exceeds the coefficient of friction of an inner surface of the floating sleeve 50, the floating sleeve 50 rotates with the outer race 20 until a new unworn surface of the self-lubricating bearing material 52 is presented to the load area of the outer race 20. This precessing of the floating sleeve 50 continues until the entire surface area of the self-lubricating bearing material 52 is worn, thus extending the track roller bearing life.

Title: Vertical-shaft motor
Inventor: TOKIWA NOBUYUKI
IPC: H02K9/02
Filed: 1987-10-12
Abstract: PURPOSE:To make the body dimensions (particularly outside diameter dimension) of a motor small by guiding the outside air through the inner part of a hollow shaft as a ventilation path and by sending a cooling wind from ventilating holes to a rotor core. CONSTITUTION:Ventilating holes 121-n are provided in the wall surface of a hollow shaft 12 and the outside air is guided into said shaft 12 by a fan not shown in the drawing so as to flow in the direction of the arrow. That is, the inner part of the hollow shaft 12 forms a ventilation path and a cooling wind passes through said ventilating holes 121-n from the inner part of said hollow shaft 12 and goes through air ducts 81-n of a rotor core 8 via an arm 17 to cool said rotor core 8. Said cooling wind further passes through air ducts 91-n of a stator core 9 to cool said stator core 9 and thereafter is discharged from the machine. In this manner, the radial width dimension of said arm 17 can be made small, because it is unnecessary that the arm 17 has the function of an axial ventilation path. Therefore, the outside diameter dimension of the rotor can be made small and the motor also can be miniaturized as a whole.

Filed: 1986-10-29
Abstract: PURPOSE:To enable a torque shock to be eliminated while acceleration hesitation to be prevented, by maintaining the ignition timing just before shift operation only for the predetermined time after the shift operation is detected. CONSTITUTION:A controller 22, if a gear is placed in a running position, reads by map reference or the like an ignition timing advance value in accordance with an engine operative condition from signals of an engine speed sensor and a throttle opening sensor 24. Next the controller, if the throttle opening sensor 24 detects a throttle valve 18 to be fully closed with the gear not in a running condition, decides shift operation to be started, and after the predetermined time of a timer limit, a predetermined idle advance timing value is adopted as the advance timing value. That is, the controller holds the advance timing value in accordance with the operative condition, read from a map just before the shift operation, before the predetermined time even if the shift operation is started. In this way, an engine enables a torque shock to be eliminated and acceleration hesitation to be prevented.

Title: Detecting method for stripped position of air flow on body surface
Inventor: KOSHIHARA TOSHIO
IPC: G01P13/00
Filed: 1987-10-15
Abstract: PURPOSE:To easily and clearly detect the separation position of an air flow on the surface of a body by blowing air to the body while generating a temperature difference between the body and air flow, and photographing the surface of the body by an infrared camera. CONSTITUTION:The temperature of the body 1 is held relatively higher than that of the air flow 3. In this state, the surface 5 of the body 1 is photographed by the infrared camera 6 from by the body 1. The air 3 flows in contact with the upstream area of the separation position of the air flow 3 in this upstream area, so the surface is cooled more and a drop in temperature is large and the temperature becomes low. In the downstream area, the air 3 flows without contacting, so cooling effect is small and a drop in temperature is small and the temperature is high. The separation position of the air flow 3 is therefore detected as an abrupt temperature variation position on the infrared screen of the surface 5.
