Title: Concentrated cooler for display case
Inventor: IIZUKA RYOZO
IPC: F25D21/08
Filed: 1994-01-31
Abstract: PURPOSE:To provide a concentrated cooler for a display case in which each display case can be effectively defrosted without influence of a variation in a refrigerant pressure at the time of starting the boosting. CONSTITUTION:Refrigerant is circulated to be supplied from an external refrigerator 4 to an evaporator 5a provided in a display case 5 at the time of cooling to cool a commodity containing chamber. When it becomes a time of starting the defrosting, the refrigerant is recovered to the refrigerator 4 according to an operation signal (a) from an external timer 13. After the recovery of the refrigerant is finished, a controller 12 allows an electric heater 10 to heat the evaporator 5a until a temperature of the evaporator 5a to be detected by a temperature sensor 11 becomes a defrost finishing temperature. Further, after the temperature of the evaporator 5a becomes the finishing temperature to stop the defrosting, a drip timer circuit 22 is operated to drip for a predetermined time. Then, a defrost end signal generator 21 outputs a defrost end signal (i) in response to a drip end signal (h) from the circuit 22 to turn OFF the timer 13, thereby finishing the defrosting.

Title: Power supply unit for field emission type electron gun
Inventor: TAMURA NOBUAKI
IPC: H01J37/248
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To attain a power supply unit for field emission type electron gun, which can generate stable accelerating voltage by conducting feedback control stably and accurately even at low-accelerating voltage. SOLUTION: The ground side of a detection resistor 7 is floated, for example, at a high voltage of 1kV using a high-voltage power source (additional power source) 10 so that the load current of 1.5μA may flow through the detection resistor 7, even if accelerating voltage is 0.5kV. The current value flowing through the detection resistor 7 is converted into a voltage value, and transmitted to low-voltage side by an isolation amplifier 12. Although the output voltage of the isolation amplifier 12 and the reference voltage of a reference voltage source 9 are compared by a comparison amplifier 8, the detection resistor 7 is floated at a high voltage of 1kV, so that the load current of a Cockroft- Walton circuit 6 can be increased substantially.  It is thus possible to maintain the output of the Cockroft-Walson circuit 6 at a prescribed voltage value by stable feedback control, even in the case of use in such a low-accelerating voltage condition as an electron returns from an anode 5 to an extracting electrode 3.
