Existing modems of time division duplex (TDD) type can be utilized without modification to perform a high speed wireless communication with stable communication quality in other frequency bands such as quasi-millimeter to millimeter wave bands. There are included a circulator (11) connected to TDD modems (1, 2) and receives signals transmitted thereby to output those signals from a first connection terminal (p1) and outputs signals received at a second connection terminal (p2) to the TDD modems (1, 2), and a frequency converter (2a) that raise the frequency of the signals from the circulator (11) by a predetermined frequency width and lowers the frequency of signals from a receive antenna (32) by a predetermined frequency width. It may be arranged that the frequency conversion width be made different between the uplink and downlink and that a filter, which blocks the transmitting wireless frequency and passes the receiving wireless frequency, is provided between the receive antenna (32) and a frequency converter (22a).

A motor-driven compressor is formed integrally with a compression portion and a motor for compressing refrigerant. The motor-driven compressor includes a drive circuit for controlling the driving of the motor. The drive circuit is incorporated into a refrigerant suction side portion of the motor-driven compressor. The motor-driven compressor may be made small and inexpensively, as well as the total system which includes the drive circuit. The assembly of the system may also be more easily facilitated. Further, electromagnetic radiation from an inverter of the drive circuit may be shielded.

A power circuit of an air conditioner for electric vehicles includes a high voltage power source, a drive circuit for driving a compressor motor, and a capacitor connected between a positive side coupling and a negative side coupling to the high voltage power source. The power circuit comprises a diode provided in the positive side coupling and a switching element provided in the negative side coupling. The capacitor is charged by the pulsed operation of the switching element which is controlled by an operation control device. The capacitor may be quickly charged in a stable condition without burdening the devices in the power circuit. Consequently, the air conditioner may be quickly started.

A strain detector wherein the efficiency of a detecting coil is improved to improve the sensitivity of the strain detector. The strain detector comprises a magnetic layer made of a soft magnetic material having a high permeability and fixedly mounted on an outer periphery of a driven shaft strain of which is to be detected, and a detecting coil disposed around the magnetic layer with a gap left therebetween for detecting a variation of the permeability arising from strain of the magnetic layer caused by an external force applied to the driven shaft. The strain detector further comprises a metal layer made of a non-magnetic material having a high electric conductivity and disposed in the gap between the magnetic layer and the detecting coil. Or else, the detecting coil has a pair of coil portions connected to each other by way of an intermediate portion thereof, and an electric current flows in the same direction through the coil portions.

摘要:
A strain detector for detecting a strain developed in a shaft applied with a torque comprises strain-sensitive magnetostrictive elements attached to the shaft in two groups in a chevron pattern. A pair of annular detection coils are wound around a bobbin to surround respective one of the groups of magnetostrictive elements. Two annular yokes made of a soft magnetic material of high permeability are disposed around respective coils across radial gaps. A hollow cylindrical shield of non-magnetic material with a high electrical conductivity is disposed around the two yokes across radial gaps. The magnetostrictive elements may be made of a nickel-iron alloy of 45 to 55% Ni-Fe. The yokes may be made of a nickel-iron alloy of about 80% Ni-Fe or alternatively, of a 6.5% Si-Fe steel. The detector may comprise a second magnetic shield disposed around the first shield of non-magnetic material with a high electrical conductivity. The second shield may be made of the same magnetic material as the yokes.
