摘要： A pulse action facial massager apparatus including a headset assembly for mounting to a user's head. A pair of flexible extension fingers extending from opposite sides of the headset assembly each of which is operably coupled to a vibrating device each generating an independent vibrating action. A tip portion of each extension finger is manually movable for selected contact at independent portions of the user's head. Hence, the respective vibrating device transmits the vibrating action thereof along the extension finger to the respective tip portion. Each vibrating device includes a motor that is controlled by an electronic controller mounted on the headset assembly. The controller permits user-variation of the repetition rate and duty cycle of the motors. This permits the user to vary the vibrational patterns produced by the present invention. In an automatic mode, duty cycle is automatically varied by a sawtooth waveform to produce a dynamically changing pattern of massage intensity. The control also includes a timer that after a preset time gradually diminishes the duty cycle and thus the intensity of the vibrations.

摘要： A controller of a DC brushless motor comprises a microcomputer. The microcomputer receives signals from three hall elements being disposed in association with the DC brushless motor and for detecting the rotating position of a rotor magnet of the DC brushless motor. On the basis of the position detecting signals, the data of the rotating number of the rotor magnet may be evaluated. When the number of the rotation thus evaluated is below the predetermined rotating number, the microcomputer stops the power supply to the DC brushless motor from a switching power source. In order to evaluate such data of rotating number, an internal interruption is started at every predetermined period in the microcomputer. The microcomputer determines at every internal interruption whether or not a counter which is reset at each rotation of the rotor magnet has overflowed, and the data of rotating number is evaluated on the basis of repetition times of the internal interruptions and periods required for such overflow.

摘要： A low pressure control system for chemical vapor deposition (CVD) apparatus, including a vacuum pressure chamber and an exhaust pump, is provided by a vacuum pump DC motor which is supplied power from a DC motor speed controller coupled to a DC control input signal from a pulsewidth modulation DC converter. The converter receives a single pulsewidth modulated pulse train having its percentage of modulation controlled in accordance with a DC to pulsewidth modulation controller which operates in accordance with the difference between a pair of DC input signals corresponding to the actual pressure inside the vacuum pressure chamber and a desired or set point pressure respectively. The vacuum pump motor speed and accordingly the exhaust pump is controlled with a high degree of precision, thereby providing improved coating uniformity of semiconductor wafers being fabricated by the CVD apparatus.

摘要： A speed control circuit for a DC motor has a phase comparator to which is supplied a theoretical frequency, emitted by a clock pulse generator, and an actual frequency, emitted from a pulse transmitter connected to the drive shaft of the motor. A first rotation direction signal, obtained from a rotation direction indicator, and a second rotation direction signal, obtained from the comparator, are combined in a logic element, the output of which is supplied to a drive circuit for driving the DC motor. A reference voltage is also supplied to the drive circuit, the reference voltage being obtained from another output of the comparator and supplied to the drive circuit through a filter. The reference voltage is a DC voltage which is proportional to the amount of phase deviation detected by the comparator. This reference voltage is utilized by the drive circuit to set the proportional value of the current supplied to the DC motor.
