Title: Bias power source circuit for semiconductor testing device
Inventor: NAGATA TAKAHIRO
IPC: G01R31/28
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To provide a bias power source circuit which does not cause ringing nor oscillation when the level of a bias power source fluctuates even when a large-capacitance electrolytic capacitor for low frequency is connected to a device to be measured at the time of conducting AC tests on the device. SOLUTION: When AC tests are performed on a device 12 to be measured, an electrolytic capacitor 10 for low frequency is connected to the device 12 in addition to a by-pass capacitor 9 for high frequency by turning on a switch 11 and, at the same time, a capacitor 7 for a compensating phase is connected to the device 12 in addition to a capacitor 6 for compensating phase connected between the output terminal and inverted input terminal of an amplifier 1 by turning on a switch 8. In this case, the occurrence of ringing or oscillation is suppressed when the level of a bias power source fluctuates by making the resultant capacitance of the capacitors 6 and 7 for compensating phase the optimum when the by-pass capacitor 9 and electrolytic capacitor 10 are connected to the device 12.

Title: Refrigerating compressor and refrigerating air conditioner
Inventor: KAWAKAMI TETSUJI
IPC: F04C29/00
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To restrain the appearance of a decomposable product insoluble in a coolant by using ether oil or the like as oil for coating the parts of a refrigerating compressor, regarding the refrigerating compressor where hydro- fluorocarbon is used as a coolant and ester oil or the like as refrigerator oil. SOLUTION: A totally enclosed reciprocating compressor draws a coolant returned from an evaporator, through a suction port 1 and then converts the rotating motion of an electric motor 3 into the reciprocating motion of a piston with a crankshaft 4 through a connecting rod 5. The coolant is thereby drawn into a cylinder 7 and raised in pressure. Thereafter, the coolant is discharged from a delivery port 2. Also, hydro-fluorocarbon is used as the coolant, and at least one of ester oil, ether oil and carbonate oil is used as refrigerator oil. In this case, ether oil and/or carbonate oil is used as an oil applied to compressor parts. Thus, the oil and the coolant are dissolved into each other, thereby preventing the deterioration of a refrigerating function due to the flow of the refrigerator oil to a refrigeration cycle.
