Title: Magnetic bearing device
Inventor: OYAMA ATSUSHI
IPC: F16C32/04
Filed: 2001-06-15
Abstract: PROBLEM TO BE SOLVED: To miniaturize a magnetic bearing device by dispensing with a distance sensor. SOLUTION: Ring-shaped two electromagnets 10a, 10b and permanent magnets 16a, 16b are mounted through a controlled member 30, and a PWM power source 15 applies the electric power to a bridge circuit composed of the electromagnets and two load elements 17a, 17b. A signal processing circuit 18 receives signals from output terminals OUT1 and OUT2 of the bridge circuit, and operates the difference in amplitudes of the receives signals. When the controlled member 30 is displaced in the a or b direction, the difference in amplitudes is not zero, so that the signal processing circuit 18 operates the adjustment voltage to equalize inductances of two electromagnets 10a, 10b.  The adjustment voltage is compensated by a compensating circuit 14 to stabilize the close circuit characteristic of a control system, and supplied to the PWM power source 15, whereby the PWM power source 15 adjusts the outputted average voltage by modulating pulse widths.

Title: Refrigerator
Inventor: TANAKA MASAAKI
IPC: F25B5/02
Filed: 2001-06-19
Abstract: PROBLEM TO BE SOLVED: To provide heat absorption load constitution of heat insulation casing body to efficiently perform stable control of temperature during cooling operation of a refrigerator. SOLUTION: A first evaporator 5 and a second evaporator 6 are respectively situated in a fresh food storage compartment 1 and a frozen food storage compartment freezer 2. The refrigerant circuit of the first evaporator 5 and the refrigerant circuit of the second vaporizer 6 are switched by a flow passage switching valve 9 for cooling. Since the heat absorption load amount of the frozen food storage compartment 2 during stable operation on the standard cooling condition of a refrigerator is equal to or less than the heat absorption load of the fresh food storage compartment 1, cooling operation time of the compartment 1 being high in refrigerating capacity can be maintained by restricting cooling operation time of the compartment 2 low in refrigerating capacity.  Since an operation rate is prevented from being reduced to an extremely low value, control of the temperature of the compartment 1 is facilitated and a cooling loss during starting of a compressor 3 is suppressed and efficient operation is realized.
