摘要： When a signal of a double frequency is generated from the original signal, conventionally a 90-degree phase-shift circuit is necessary to suppress an output of a DC component and efficiently obtain a double wave. According to the present invention, an equal RF signal is inputted to input terminals and an output is matched with a frequency as high as that of the original frequency in a Gillbert cell double-balanced mixer, so that a doubled output is obtained with no DC offset. According to the circuit configuration of the present invention, it is possible to provide a circuit readily performing integration and to efficiently output only a double frequency merely by inputting a simple differential signal without the need for the original signal which has been phase controlled. Further, a DC short circuit in the resonance circuit makes it possible to eliminate a DC offset voltage in an output.

摘要： A liquid crystal panel is turned on upon power ON, and wastes electric power. A liquid crystal drive circuit of this invention has a shift register (111) for receiving an input signal IN and a clock CLK, and shifting the signal IN, an output selection circuit (112) for receiving a shifted signal Q1 and a frame signal FR, and outputting signals SEL1 to SEL4, an output buffer (113) for receiving the signals SEL1 to SEL4 and voltages V1 to V4, and outputting one of these voltages, a selection control circuit (21) for receiving signals Q157 to Q160 output from shift register units in four continuous blocks from the final stage, and for determining abnormal operation and outputting signals S1 and /S1 when all the input signals are at a predetermined level, and a clock control circuit (12) for inputting a given signal to the shift register unit (111) upon reception of the signals S1 and /S1 so as to make the shift register unit (111) operate as an inverter array. Usually, upon power ON, the internal signals assume unknown values, and the liquid crystal panel wastes electric power if it is turned on in such state. When the liquid crystal panel is set in a non-display state by the above arrangement, however, consumption power can be reduced.

摘要： A magnetically coupled pump comprising a housing whose interior is partitioned into a pump chamber and a motor chamber by a partition wall. An impeller is mounted in the pump chamber. The stator of the motor is mounted in the motor chamber. The rotating shaft of the impeller is received in a recess formed in the partition wall. The rotating shaft is held by a bearing mounted in the recess. An annular permanent magnet is mounted to the side of the body of the impeller which faces the partition wall and arranged about the rotating shaft. An annular sliding contact portion is formed at an end of the bearing and makes a sliding contact with the side of the body of the impeller facing the partition wall. A pair of annular auxiliary sliding contact portions are formed in a part of the rotating shaft and in a part of the bearing, respectively. The auxiliary sliding contact portions start to make a sliding contact with each other when the annular sliding contact portion is worn by a given amount.

The output buffer circuit also includes third and fourth transistors of a second conductivity type, having first terminals connected in common and second terminals connected to third and fourth power supplies. First and second resistors connected in series are connected between a common connecting point of the first and second transistors, and a common connecting point of the third and fourth transistors.

摘要： An apparatus for epitaxially growing a chemical-compound crystal, a plurality of raw-material gases are alternately introduced into a closed chamber of a crystal growing device to grow the crystal placed within the closed chamber. At growing of the crystal, a light from a light source is emitted to a crystal growing film of the crystal. Intensity of a light reflected from the crystal growing film and received by a photo detector is measured. Charge amounts of the respective raw-material gases are controlled by a control system on the basis of a change in the reflected-light intensity, thereby controlling a growing rate of the growing film.
