Abstract: PURPOSE:To prevent generation of an abnormal high voltage of the secondary winding of a boosting transformer immediately after the driving of a magnetron by varying the switching frequency of the switching element of a switch control circuit, in relation to the output voltage of a voltage generating circuit. CONSTITUTION:When an AC power source 1 is connected, the voltage rectified by a rectifier bridge 2 charges a smoothing capacitor 4. And the secondary voltage of a transformer 21 for control is rectified by diodes D1 and D2, compared with the voltage of a control power source Vc in a comparator A1, and when the voltage of the power source 1 is made at the voltage Vc or higher, the voltage at the input side of a pulse width modulating circuit 30 is reduced. And as the input side voltage of the pulse width modulating circuit 30 is reduced, the switching frequency is increased, and the current of the primary winding 7a of a boosting transformer 7 is suppressed. Consequently, an abnormal high voltage induced in the secondary winding 2b can be suppressed.

Abstract: PURPOSE: To utilize an enormous amount of energy source which has been not utilized but lost in the past, by utilizing thermal energy by conventing it to the other energy even there is no difference of temperature.  
     CONSTITUTION: A medium material 5 is circulated from a liquefying chamber 3 through a pump 4, evaporating chamber 1 and turbine 2 to the liquefying chamber 3. Absorbed energy in a heat absorbing part of the evaporating chamber 1 or the like is converted into easy to utilize energy in an energy converting part of the turbine 2. When the pump 4 is driven by electric power of 1W, thermal energy of 2W is absorbed by the heat absorbing part of the evaporating chamber 1 and radiated from a heat radiating part of the liquefying chamber 3 as heat of 3W. Then if assumed 2W of the 3W amount of energy is generated in the energy converting part of the turbine 2 as electric power, an amount of 1W is radiated as thermal energy, thus a difference amount 1W of thermal energy can be converted into a difference amount 1W of electric power.
