Patent JP-H0634258-A (JP)
Title: Electrical refrigerator
Inventor: NIIHAMA YOSHINORI
IPC: F25D21/08
Filed: 1992-07-21
Abstract: PURPOSE:To shorten a defrosting operation time and restrict an excessive increasing of temperature at a freezing chamber by a method wherein frost is rapidly melted with a high heating amount at its initial stage, a heat generating amount of a defrosting heater is reduced to its half value at a later stage and a surplus heat at the previous stage is also utilized to perform a defrosting operation. CONSTITUTION:As an electrical energization for defrosting heaters 10 and 11 is started at a defrosting starting time (t1), temperatures over and below an evaporator 4 detected by temperature sensors 12 and 13 are increased. A reason why the temperature at the lower part of the evaporator 4 is increased faster than the upper part temperature consists in the fact that the evaporator is placed near the defrosting heaters 10 and 11. As the lower part temperature of the evaporator 4 reaches an electrical energization stopping temperature of each of the defrosting heaters 10 and 11 preset at the time (t2), the electrical energization for the defrosting heater 10 is stopped and subsequently the electrical energization only with the defrosting heater 11 is carried out until the upper part temperature of the evaporator 4 detected by the temperature sensor 4 reaches the electrical energization stopping temperature. Then, as the upper part temperature of the evaporator 4 reaches the electrical energization stopping temperature, the defrosting heater 11 is also stopped in its electrical energization.

Title: Power source for energizing superconductive coil
Inventor: MOROHOSHI KOUKI
IPC: H02M1/15
Filed: 1981-12-02
Abstract: PURPOSE:To generate a voltage of the direction for cancelling the ripple component at the primary coil of a transformer by detecting the ripple voltage and current and controlling the energization of the secondary coil of the transformer based on the synthetic signal of both. CONSTITUTION:In case that the ripple components are contained at both terminal voltages of a superconductive coil 3 when a permanent current switch 6 is OFF, an active filter 12 is driven based on the ripple component contained at both terminal voltage of a resistor 16. When the switch 6 is ON, the filter 12 is driven by the ripple component contained in both terminal voltage at a shunt 7. In this manner, the ripple components can be removed irrespective of the state of the coil 3 and of the rise and fall of the current having small time constant.

Title: Incline magnetic field generator
Inventor: SAWADA RYOICHI
IPC: A61B5/055
Filed: 1990-07-23
Abstract: PURPOSE:To decrease extremely noise from incline magnetic field generating coils, by arranging in immersion a bobbin wound around with the incline magnetic field generating coils, within a container enclosing a liquid having an electrical insulation quality. CONSTITUTION:Even if incline magnetic field generating coils 10 electrified by means of a power source portion 21 oscillate so as to strike an incline coil bobbin 6 as they receive stress due to the mutual operation of the electrification electric current and incline magnetic field, their oscillation waves are about reflected at a border surface (container wall surface) between a liquid within the liquid enclosing container 5 and gas outside the container 5, so oscillation liquid propagated to the outside of the container 5 is damped greatly. Also, an oscillation damping velocity within the liquid becomes faster enough for its high viscosity when compared to that within the gas, so this together with the above reflection operation makes striking sounds extremely decreased.
