Title: Motor
Inventor: ARITA YOJI
IPC: H02K29/00
Filed: 1989-11-02
Abstract: PURPOSE:To suppress torque ripple in a three-phase coreless motor by containing higher harmonics in the distribution of widthwise distance of magnetic poles at a field section comprising permanent magnets. CONSTITUTION:A coreless motor comprises a field section 1, an air core coil 4, and the like. Assuming the number of pole at the field section 1 is (m), the number of three-phase air core coil 4 is (p), a pair of N and S poles occupy one period T in the rotary angle direction of a motor, the widthwise distance h(theta) of the pole can be expressed in term of the rotary angle theta by a formula shown on the drawing where any one of coefficients b2i+1, b2i-1 has a value not equal to zero. Here, ho= H(0<=theta<pi), ho=-H(pi<theta<=2pi), and negative sign is considered variation of the polarity. Assuming (q) is the greatest common measure of m/2 and (p), i = p/q. When the number of pole at the field section 1 is 4 and the number of the air coil is 3, the profile at the field section 1 is determined by adding fifth higher harmonic by 7% to a normal profile in the widthwise direction thus achieving torque ripple reduction effect.

Title: Leakage information displaying device
Inventor: KIOKA HIROMI
IPC: G08B23/00
Filed: 1988-11-14
Abstract: PURPOSE:To reduce the range of leak generation and provide possibility of identifying the current leak generating point by calculating the distance from the leak sensor installed point to a bend of a piping within a circle indicating the range where leaks are presumed to be generated, and by indicating a circle with the dia. shrunk in accordance with this distance by reference to this bend as the center. CONSTITUTION:A leak sensor 1 measures leak sound on a piping system, and the share of time in which the leak sound exceeds a certain level, is calculated in the form of time integral rate, and the distance from the point at which the leak is generated actually is determined from the frequency of the leak sound. The leak distribution is expressed on a map with circles in sizes corresponding to the distance data of the leak points from the measuring point. If the bent of the piping lies within a displayed circle, the presumative range of leak points is shrunk one by one associate with the piping length to serve for correlational apprehension between a different pieces of leak sensing information, and thus the actual leak point is identified.

Title: Superconductor
Inventor: NOJI HIDEKI
IPC: H01B13/00
Filed: 1994-10-25
Abstract: PURPOSE: To reduce the rate of decrease in critical current value due to a self-magnetic field and to prevent localized application of mechanical pressures and a decrease in superconducting characteristic by causing helical grooves provided in both inner and outer pipes to be twisted in opposite directions at each pipe. CONSTITUTION: A plurality of helical wires 3 are formed in each of inner 1 and outer 2 pipes whose insides serve as refrigerant passages, and superconducting wires 4 are fitted into the grooves 3. In this case, the pipes 1, 2 have their grooves 3 twisted in opposite directions (clockwise and counterclockwise). Therefore, the wires 4 are also twisted in opposite directions, and magnetic fields produced in the directions of the axes of the pipes are opposite to each other at the inner and outer pipe layers. As a result, when the magnetic fields produced in the directions of the axes have the same magnitude they cancel out each other, so that the rate of decrease in critical current value due to a self-magnetic field can be reduced.  Since each of the wires 4 is secured in the corresponding groove 3, a decrease in superconducting characteristic as a result of localized application of mechanical stresses to the wires 4 is prevented.

IPC: A01G31/00
Filed: 1988-11-11
Abstract: PURPOSE:To reduce flowing of nutrient solution into motor chamber by covering and engaging periphery of motor chamber with nutrient tray having solution leakage-stopping edge higher than overflowing edge. CONSTITUTION:A pump 2 is driven by motor 3 and nutrient solution in a nutrient solution tank 1 is pumped up into upper tray 9 for nutrient solution and a nutrient solution chamber 5. Next, the nutrient solution is flowed from the chamber 5 to a water-culturing bed 6 and subjected to nutrient absorption by plant, then remained nutrient solution is returned into the nutrient solution tank 1 and circulated. In a case of overflowing of nutrient solution pumped-up with the pump 2 from the nutrient solution-receiving tray 9 to outside, the solution is stopped by a solution leakage-stopping edge 8 formed higher than overflowing edge 7. Further, said overflowing edge 7 is attached to the nutrient solution chamber 5 connecting the lower side with said nutrient solution- receiving tray 9, thus the nutrient solution is fed to the water-culturing bed 6. Therefore, said overflowing edge is not contact with motor chamber 4, thus amount of flowing or penetrating into the motor chamber 4 of nutrient solution flowing out from the overflowing edge 7 to the water-culturing bed 6 is small.

Title: Automobile clutch control method
Inventor: MORISHITA AKIYOSHI
IPC: B60K23/00
Filed: 1992-09-30
Abstract: PURPOSE:To prevent vibration such as the knocking phenomenon of an automobile so as to obtain a smooth engine brake feeling by decreasing an exciting current to be fed to a powder clutch gradually according to the vehicle speed at the time of decelerating with a foot kept off an accelerator during travel. CONSTITUTION:In the case of a power switch being turned off with a foot kept off an accelerator during travel, a fixed exciting current for putting a powder clutch 3 into the direct-coupled state is outputted to the clutch 3 on the basis of the engine speed from an engine rotation sensor 5 and an opening signal from a throttle sensor 7. A control device 4 is stored with slip factors for obtaining the semi-clutch state in relation to the vehicle speed. On the basis of this, a slip factor is read in correspondence with a signal from a vehicle speed sensor 8, and an exciting current for obtaining this slip factor is computed in the control circuit 4 and outputted to the clutch 3. The high exciting current value for maintaining the direct-coupled state is thereby lowered gradually to the low exciting current value, and the locking force of the clutch 3 is gradually weakened according to the decrease of vehicle speed so as to prevent the knocking phenomenon or the like of an automobile.
