Title: Modulo-w circuit
Inventor: ISHIZUKA TERU
IPC: G06F7/38
Filed: 1987-06-27
Abstract: PURPOSE:To improve the trouble detecting rate of a check circuit by defining the wrong binary data [1, 1, ..., 1] as the modulo value when a trouble is detected in consideration of said wrong binary data [1, 1, ..., 1]. CONSTITUTION:A modulo-3 production circuit 301 has a trouble and the value D=[1, 1] of a modulo-3 is obtained in terms of the sum Z of two binary data X=[0, 1, 1, 0] and Y=[0, 1, 0, 1]. A modulo-3 expected value generating circuit 302 has a trouble and the sum C=[1, 1] is obtained between the values of X and Y modulo-3. An arithmetic circuit part has a trouble and Dnot equal to C is obtained. Then the output M=[1, 1] is obtained due to a trouble of a modulo-3 circuit 303. Then the output M=[1, 1] is obtained in any case of said troubles and therefore it is detected that a circuit preceding the output M has a trouble. Then the value [1, 1] of the modulo-3 showing a trouble is outputted to a check circuit of the following stage. Thus the occurrence of a trouble can be decided with input of the value [1, 1]. In such a way, the error detecting rate of the check circuit is improved.

IPC: H02P7/295
Filed: 1982-09-14
Abstract: PURPOSE:To reduce the number of parts by converting the frequency of a signal which is transmitted from a controller into a voltage and varying the time constant for deciding the phase angle of a firing pulse of a thyristor by the voltage. CONSTITUTION:A controller which is provided separately from a sewing machine body radiates a carrier electromagnetic wave which is pulse-modulated from the rectangular wave signal of the frequency in response to the operation of a movable section. A receiver removes a carrier component by a rectifier (f) to produce a rectangular wave signal, which is applied through an amplifier (g) to a monostable multivibrator (h). The output pulse of the multivibrator (h) is converted by a low pass filter (i) into a voltage, and is then applied to an LED of a photocoupler PC. The impedance between the collector and the emitter of the output side phototransistor is varied, thereby altering the time constant of a phase control circuit.

Filed: 1993-06-29
Abstract: PURPOSE:To control the high frequency of induced voltage without limiting the number of slots by selecting the pitches of a stator winding where the winding coefficient to slot high frequency of a rotor is minimum, and selecting the pitch to the winding of the rotor where the winding coefficient to slot high frequency of a stator is minimum. CONSTITUTION:In example where three-phase windings U, V, and W are settled on the iron cores 1 and 2 with slots of a stator and a rotor and the numbers of slots per pole are 26 pieces for the stator and 30 pieces for the rotor, when the pitches of a stator winding 83.3%, the winding coefficient to 29th and 31st high frequency being slot high frequency of a rotor becomes minimum. Moreover, when the pitches of stator winding is 80.0%, the winding coefficient to the 35th and 37th high frequency being slot high frequency of a stator becomes minimum. This way, the high frequency contained in induced voltage can be reduced without giving limitation to the number of slots by selecting the pitches of stator winding and rotor winding optimally.
