Title: Rice boiler
Inventor: FUKUDA TAKANORI
IPC: G05B13/02
Filed: 1991-02-14
Abstract: PURPOSE:To enable the amount of boiled rice to be precisely judged by performing fussy reasoning based on the initial temperature of an inner pot detected by a detecting element and a temperature increasing rate obtained by a circuit. CONSTITUTION:The temperature of an inner pot 1 is detected by a thermister 2 acting as a detecting element. Since the initial temperature of the inner pot is considerably different by season, the amount of boiled rice is forecasted more precisely with the initial temperature made an input variable. In an operating circuit 9, the average value of temperature increasing rates at several points is operated by differentiating the output of the thermister 2 in the vicinity of temperature between a first and a second temperature which are set in advance, so that the average value obtained is made to be an input value for fussy inference. In a fussy inference means 8, the smallest value by each rule is selected as an adaptation. And next, the membership function value of each corresponding output variable label is multiplied by each adaptation of input variables by each rule, and the sum of all of those multipliers is divided by the sum of the adaptation of input variables, so that the amount of boiled rice is thereby computed.

Title: Trouble detecting method for load sensor in internal combustion engine
Inventor: FURUKAWA HIDEO
IPC: F16H45/02
Filed: 1987-01-30
Abstract: PURPOSE:To improve the reliability of trouble detection, by judging a load sensor to be out of order at a time when the output shaft speed of a hydraulic torque converter is less than the input shaft one and the speed difference is larger than the specified value in the state that output signal value out of the load sensor is less than the specified value. CONSTITUTION:The detected throttle valve opening thetaTH of a throttle valve opening sensor (engine load sensor) is within the range of normal value, but when it is smaller than the specified value approximate to idle opening, and a vehicle runs at more than the specified speed, it is considered to be the decelerated state of an engine E from a higher state in car speed, by way of example. Therefore, speed NOUT of an output shaft 2 of a hydraulic torque converter T ought to be higher than speed NIN of an input shaft 1. That is to say, a speed ratio (e)=NOUT/NIN should come to more than 1.0. Accordingly, although the throttle valve opening thetaTH is smaller than the specified value, when the speed ratio (e) is yet smaller than the specified value smaller than 1.0, it should be so estimated that trouble occurs in a throttle opening sensor.

Filed: 1979-02-24
Abstract: PURPOSE: To very easily form a fixed gap at the tip of a tape wound core by shaving a part of the circumferential core which is longer than the tape wound core.  
     CONSTITUTION: One side of a core A is inserted and pinched on a supporting stand 4 by a jig 5 and ground by a roller blade 6 and the height of a circumferential core 2 is maintained at the same height of a magnetic core 3. Therefore, even if a part of the tip of the circumferential core 2 is lost and fallen, the core A is mutually stuck to the core B which forms a gap G 1  by the other surface. Therefore, the gap G 1  is formed between mutual tape wound core 3. To form the desired dimensional gap G 2 , the grinding method for the tip of the circuit core may properly be changed. In this way, B side of the tape wound core which sets the gap is remained as it is at the time of forming and grinding is performed for only contacted and adhered circumferential core at the A side of the tape wound core and the gap will be formed easily and accurately.
