摘要： A phase locked loop (PLL) circuit is provided to operate in a broad band, including two separate loops one of which is for feed-back of an output from an oscillator to the same oscillator through its associative proportional control unit and the other of which is for feed-back of an output of an oscillator to the same oscillator via an integral control unit. The proportional control unit is arranged to control an output frequency of the oscillator and is operable to generate a control signal based on a difference between input and output signals. The integral control unit is arranged to control the phase of an output signal of the oscillator to thereby generate a control signal based on a phase difference between input and output signals.

摘要： A waveform shaping circuit is provided so that the duty factor of clock pulses can be set to 50% with high accuracy even if the clock pulses are of a low voltage and a high frequency. An inverter which receives the clock pulses through an alternating current coupling capacitor is provided with a non-linear limiter element for limiting an amplitude of an output symmetrically on positive and negative sides thereof. A first current-limiting impedance and a second current-limiting impedance are connected between a power supply side terminal of the inverter and a power supply bus and between a grounding side terminal of the inverter and a grounding bus, respectively.

摘要： An over-current detection circuit using the ON-voltage of a main MOSFET is provided, which is resistant to process variations of a main MOSFET and is not easily influenced by switching noise. Separately from a main MOSFET (Q1), a sense MOSFET (Q3) whose size is 1/m of the main MOSFET is provided and it is caused to be normally on.

The ON-voltage when the main MOSFET is on is sampled and held, and it is obtained as a DC voltage. These DC voltages are compared in a comparator (COMP).

摘要： The present invention relates to a complementary transistor circuit and, an amplifier using it, and in particular, to a video amplifier for amplifying video signals and a high-definition CRT display device. In amplifying inputted video signals by using a multiplexer, a gain controller and a current mirror amplifier, each element circuit is formed by using complementary transistor circuits. Circuit simplification is thus attained. In addition, higher precision and band broadening has been realized owing to adoption of a current operation. Further, the present invention makes it possible to eliminate direct from the high voltage output completely by providing a low-voltage output circuit for feedback having a similar relationship with respect to the high-voltage video output stage of the video amplifier, thereby performing negative feedback via a sample-and-hold circuit. This also serves to broaden the bandwidth and reduce power dissipation.

摘要： An electrostrictive revolution type ultrasonic motor includes a piezoelectric ceramic disk shaped stator and a rotor. The piezoelectric ceramic disk shaped stator has an eccentric movement via excitation by two phase pulse like voltage. The rotor is fitted around the circumference of the stator and is transmitted by a rotating torque due to the eccentric movement via frictional contact therebetween. The rotor is formed of a plastic material by injection molding to achieve a reduction of a size variation of the rotor and a stable contact with the stator. A high and stable rotating torque is thereby obtained with a reduced production cost. Further, a driving device for the ultrasonic motor which varies the frequency of a voltage applied to the ultrasonic motor in a stepped manner discriminates the magnitude of the corresponding motor currents and drives the ultrasonic motor with the frequency which causes the maximum motor current. In this manner, a simple structured and low cost driving device which operates at a high speed and at a high resolution with a high efficiency is achieved.
