Abstract: PURPOSE:To improve the accuracy and reliability of a measured value by recording plural frame each in a prescribed current, obtaining the maximum output value by regenerating each frame, and also, averaging the maximum output values of each frame, executing this operation, while changing a recording current, and measuring a regenerative characteristic. CONSTITUTION:In a prescribed current value, plural frames each are recorded, the maximum output values (a), (b), (c), (d) and (e) are obtained by regenerating each frame 1, 2, 3, 4 and 5, and also, the maximum values (a)-(e) of each frame 1-5 are averaged. Subsequently, a reproducing characteristic is measured by executing this operation, while changing a recording current. In such a case, by constituting a measuring system by using a computer, a data processing can be executed easily and exactly by the computer, and the regenerative characteristic can be measured quickly.

Abstract: PROBLEM TO BE SOLVED: To accurately detect a torque with a simple constitution by transmitting a driving force by a rotor changing at its relative position by the torque, detecting a change in a resonance frequency responsive to the change of the relative position without contact, and transmitting a modulation signal without contact. SOLUTION: An oscillator 61 oscillates a sine wave signal according to a resonance frequency of a resonator and outputs a signal so as to change an oscillation signal in response to a pedal power. In a motor driven bicycle 31, this sine wave signal is amplified by an output circuit 63, and then transmitted to a frame side through coupling elements 54A, 54B without contact. Then, an output signal of the element 54B is frequency divided by a frequency divider 66, then band-pass limited by a high-pass filter 67, and detected. This detected result is integrated by a low-pass filter 68, and a torque detection signal changed at its DC level in response to a frequency of the sine wave signal, i.e., the pedal power is detected. The torque can be detected without contact by detecting the resonance frequency changing according to the pedal power.

Abstract: PURPOSE: To realize fine rotational control by employing a short-circuit brake for a small current and a reverse current brake for a large current in the brake control for a three-phase motor. CONSTITUTION: A comparator 4 compares the voltage for driving a three-phase motor 1 integrated through a resistor 5 and a capacitor 6, and a driver 10 drives the three-phase motor 1 depending on the control signals Uu, Ui, Vu, Vi, Wu, Wi received from a logic section 9. Switching between a short-circuit brake and a reverse current brake is carried out by sampling the PWMin signal at a timing for maximizing the pulse width in PWM modulation. A short-circuit brake is applied when the sample output, i.e., a PWM inverted Short/Rev signal, has Low level otherwise a reverse current brake is applied.

Abstract: PROBLEM TO BE SOLVED: To detect an overall mass of a vehicle having a moving unit from detected information of its motion in the unit having an auxiliary power source. SOLUTION: The moving unit 1 has an auxiliary power source SS for a main power source MS, and moves together with a drive subject of the power source MS. An acceleration 'at' of a vehicle (moving object having the unit 1 and the subject) of the case of driving the power source SS by a predetermined force 'Fa' and an acceleration 'αn' of the vehicle of the case of driving the power source SS by a force 'Fa'' different from the force 'Fa' are detected. An overall mass 'M' of the vehicle is calculated as a value of a ratio of dividing a difference 'Fa-Fa'' of the force by the power source SS by difference information 'αt-αn' of the accelerations, an auxiliary power value is obtained from this, and the power source SS is controlled.

Abstract: PURPOSE: To ensure accurate drive of a motor by turning the upper and lower layer transistors of each phase OFF simultaneously for a predetermined time at a switching timing in the rotational direction thereby preventing through current. CONSTITUTION: The motor driver detects the position of the rotor based on the counter electromotive forces induced in the coils 1U, 1V, 1W of respective phases and switches the conducting state depending on the detection results thus driving a three-phase motor 1. Current values of upper and lower layer transistors are detected as the current fed to the coils 1U, 1V, 1W of respective phases and employed in the formation of a comparison output Verr from a comparator 4. Since a through current causes trouble in the accurate drive control of the three-phase motor 1, a timing controller turns the upper and lower layer transistors OFF simultaneously and produces an output open signal for preventing the through current.

Abstract: PURPOSE:To get accurate timing signal by feeding back a signal, which is made based on the voltage at the middle between the outputs of first and second integrating circuits, to the integrating circuit, in a driving circuit which applies a current based on the timing signal whose phase is delayed by a specified angle from the zero cross point of the counter electromotive voltage of a driving coil. CONSTITUTION:A feedback circuit 103 gets the voltage VCENT at the middle between the output signals K'1 and K'2 of integrating circuits 6 and 7, and feeds back the differential voltage with the reference voltage to amplifiers 101 and 102 as feedback voltage VB so as to give its noninverted signal VSY and inverted signal VSO. On the other hand, the polarities of the integrating circuits 6 and 7 are changed over by changing switch circuits S3 and S4 by the signal j from a buffer 8 and the signal j' from an inverter 9 of a signal g, which are inverted at each zero cross point of the counter electromotive voltage of each phase of a driving coil, and also the gain is controlled. Hereby, a timing signal, whose phase is delayed a specified angle accurately from the zero cross point of the counter electromotive force, can be gotten.
