Inventor: HINO TOSHIYUKI
IPC: F26B5/04
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To fully demonstrate capacity of a compressor sufficiently by a method wherein steam of saturated condition in a vacuum tank is heated by the suction pipe of the compressor to eliminate the wet condition of the steam and obtain superheated condition. SOLUTION: When the motor 2m of a compressor 2 is started and the operation of a drying device is started, steam is generated in a vacuum tank 1 and the steam becomes saturated condition whereby the suction steam of the suction pipe 6a becomes saturated condition. However, the switch 13 of a heater 11 for the suction pipe 6a is put ON, the suction pipe 6a is heated by a coil heater 11 and, accordingly, sucked steam is heated whereby the condensation of the steam can be prevented. In this case, when the suction pipe 6a is heated to a temperature higher than the saturation temperature of the steam, the suction steam is heated to superheated condition and it is preferable. The suction pipeline 6a is made as short as possible and the outer periphery is insulated whereby the capacity of a heat source can be a small.  According to this method, the volume efficiency of the steam compressor can be maintained and the size and weight of the superheater can be reduced.

Inventor: SENBA TETSUO
IPC: H02P29/00
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To stably perform feedback control even when mechanical resonances exist in plural frequencies in a hard disk device. etc., performing positioning control by selecting an optimum notch filter so that the useless peak of an open loop gain is lowered based on the shape of a transfer function without directly measuring the frequency at the peak of the transfer function.

A CPU 21 selects two notch filters from the memory 23 and sets these coefficients successively in the notch filters in a servo processor 9. A drive CPU 13 injects a sine wave into the servo processor 9 at every frequency of a prescribed interval to transmit a position error signal to the CPU 21. Thus, the CPU 21 calculates the frequency characteristics of control loops containing the notch filters to set the optimum notch filter.
