Title: Rotor detector for dc brushless motor
Inventor: KODAIRA YOSHIYUKI
IPC: H02P6/17
Filed: 1990-05-31
Abstract: PURPOSE:To utilize the differential output of each Hall element pair as a detecting signal by arranging a plurality of Hall elements along the locus of a rotor and forming the Hall element pairs of adjacent Hall elements. CONSTITUTION:Hall elements l, 2, and 3 are respectively used for monitoring W-, V-, and U-phases and arranged symmetrically about the locus of a rotor in the vicinity of the locus. Electric currents are supplied to each Hall element l, 2, and 3 from power lines 8 and 9 for Hall elements. The signals of the W-and Uphase monitoring elements l and 3 are supplied to the W-phase input terminals W+ and W- of a control circuit 4. Since a V-and U-phase signals are supplied to the U-phase input terminals of the circuit 4, the difference signal between the U+ and V+ becomes the U-phase input signal of the circuit 4. Similarly, the W-phase input signal is constituted of the difference signal between the W-and U-phases. The control circuit 4 controls the electric currents supplied to a W-, V-, and U-phase coils 5, 6, and 7 on the basis of these differential signals.

Title: Periodic operation controlling system for motor
Inventor: MORI KUNIYUKI
IPC: H02P29/00
Filed: 1986-06-20
Abstract: PURPOSE:To execute an optimum control of a motor by covering a scan delay of a microcomputer and a delay of a servo-device, by shifting a position of the previous deviation data to be fetched, in the forward direction (in case of a forward turn) or the backward direction (in case of a reverse turn). CONSTITUTION:The present target value Pk which has been read out of a position data table 1 by a designated position (k) of a timing generator 15 which is varied extending from I to K, and the previous deviation data sigmak+DELTAk in a deviation data table 3 designated by a position k+DELTAk which has added DELTAk to the designated position (k) of the timing generator 15 by a timing regulator 16 are fetched. In this way, by shifting a fetching position of deviation data sigma1-sigmaN of the deviation data table 3 by DELTAk in the forward direction or the backward direction, a command value is given to a motor 10 by forestalling the data by DELTAk, even in a part where a variation (speed variation) of position data P1-PN of the position data table 1 is large. In this way, a scan delay and an operation delay of a servo-device can be covered, and an operation of the motor 10 becomes near a pattern of the position data table 1 unlimitedly.

Title: Device for controlling air conditioner
Inventor: KOBAYASHI ATSUSHI
IPC: F24F11/02
Filed: 1985-06-28
Abstract: PURPOSE:To realize comfortable space cooling by discriminating the frequency of an inverter type air conditioner which determines the operation frequency by detecting the room temperature to discriminate the difference between the detected value and the preset temperature thereby to control the operation of a damper at a lower blow-off port and a fan motor. CONSTITUTION:The temperature detected by an indoor detector 9 is input to a microcomputer (LSI) 10, and is compared with a temperature set within the LSI 10. When the room temperature is greater than the set temperature, a determining device 11 determines the operation frequency in accordance with the temperature difference. A freezer (a) is operated by causing the inverter to produce the the thus determined frequency. When the operation frequency is greater than the predetermined value, the LSI 10 judges that rapid space cooling is necessary, and actuates a damper relay 12 and a down blow fan motor relay 13 to rotate a damper motor 7 and also a down blow fan motor 8. Thus, rapid space cooling is carried out immediately after the starting and when the room temperature suddenly rises up and ordinarily shower cooling is carried out from the cooling thereby to realize comfortable air conditioning.

Title: Horizontal shaft francis turbine
Inventor: KOBAYASHI KAZUO
IPC: F03B3/02
Filed: 1979-11-07
Abstract: PURPOSE: To reduce the force of load applied to a bearing mount in a turbine, by rigidly coupling the thrust bearing mount for a main shaft of the horizontal shaft Francis turbine to its head cover through struts and cancelling the force applied to the head cover and the hydraulic pressure thrust.  
     CONSTITUTION: A bearing mount 7 that supports a thrust bearing 6 of a main shaft 4 is coupled as a rigid body to a head cover 2 by a plurality of struts 14 and the  force F' applied to the head cover 2 is mostly supported to the bearing mount 7  through the struts 14. The hydraulic pressure thrust F applied to a runner 1 is  supported by the bearing mount 7 then the force finally applied to the bearing  mount 7 is such that a difference of the forces between the hydraulic pressure thrust  F and the force F' is loaded in a direction toward a draft tube 3. Here because the  hydraulic pressure thrust F and the force F' are of about the same strength, the  load applied to the bearing mount 7 can be widely reduced.

IPC: F02M37/22
Filed: 1987-06-09
Abstract: PURPOSE:To prevent stoppage of fuel supply due to shifting of fuel by arranging a first filter at the lower section of sub-tank and a second filter above intake port of fuel pump arranged in the sub-tank. CONSTITUTION:A sub-tank 2 is filled with fuel under normal operation. Fuel is sucked by a fuel pump 3 through a first filter F1 and fed through a delivery port 5. Return fuel is led through a return pipe 7 into the sub-tank 2. When fuel is shifted to one side due to cornering, a portion of the first filter F1 separates from the liquid face. The first filter F1 has higher fuel pass resistance than that of the second filter F2, because it is wetted with fuel. Consequently, fuel in the sub-tank passes through the second filter F2 and sucked by the fuel pump 3 through the intake port 4.

Title: Torque distribution device in four-wheel drive vehicle
Inventor: KODAMA YUKIHIRO
IPC: B60K17/346
Filed: 1986-06-20
Abstract: PURPOSE:To improve stability in straight running and controllability by providing a sensor to detect a handle steering angle whereby not only distributing much more torque for rear wheel driving during handle operations, but also decreasing rear wheel driving force around the neutral point of a handle. CONSTITUTION:An ideal driving force distribution value is obtained from a map 30 set in advance by a torque distribution control device 20 based on a steering angle signal from a handle angle sensor 22. Then, clutch torque to be generated by a hydraulic clutch 11 is computed based on both said value and driving torque detected by an output torque sensor 21. And then, hydraulic pressure corresponding to said clutch torque is applied to the hydraulic clutch 11. This causes rear wheel driving torque around the neutral point of a handle to be decreased, but rear wheel torque to be increased when the handle is steered. Accordingly, the stability of a vehicle during straight running and the controllability during steering can be maintained satisfactorily.
