A reactor is provided between the positive output side of the rectifier circuit and the positive side of the switch. A smoothing capacitor is connected in parallel with the switch. An inverter converts the bus line voltage to an alternating current voltage to drive a compressor. An inverter controller adjusts the duty factor of the alternating current voltage of the inverter so that the operation frequency of the compressor satisfies a compressor frequency command value. A switch ON time determination unit determines a switch ON time, within a range that is no higher than an upper limit, so as to make the bus line voltage correspond to the output power of the inverter. The lower the compressor frequency command value is, the lower a switch ON time upper limit setting unit sets an upper limit for the switch ON time.

[Chubachi Noriyoshi(No. 4-6-203, 1-Chome,Aza-Nakazaike, Arai, Sendai City), Kushibiki Junichi(No. 48,Aza-Nakazaike, Arai, Sendai City)] An acoustic microscope using a line-focus acoustic beam is disclosed. The line-focus acoustic beam is generated by an acoustic transducer head having an acoustic transducer electrode applied on a flat end surface of a sapphire rod, in the opposite end surface is formed a cylindrical concave surface. The acoustic transducer head is arranged fixedly above a mechanical stage on which a specimen is placed. The mechanical stage is movable in a Z axis, i.e. an axis of the line-focus acoustic beam and is also rotatable about the Z axis. By moving the stage in the Z-axis, a V(z) curve is obtained and a phase velocity of a leaky surface-acoustic wave is calculated from a repetition period of the V(z) curve. Then the V(z) curve measurement is repeated while the stage is rotated, and it is possible to obtain anisotropies of the specimen expressed by a relation between the rotational angle and the phase velocity of the leaky surface-acoustic wave.
