Title: Room heater with hot water
Inventor: HATA GIICHI
IPC: F24S90/00
Filed: 1980-11-28
Abstract: PURPOSE: To make the effective use of heat radiation in a hot water feeding process by a method wherein the outlet of a solar heat collector is connected to a hot water faucet through indoor and outdoor pipes arranged in parallel relationship with each other, a heat exchanger is arranged in the indoor pipe and hot water is flowed selectively into the indoor and outdoor pipes.  
     CONSTITUTION: A three-way valve 6 provided between the outlet of the solar heat water heater 2 and the hot water faucet 3 and a radiator 7 within the room on the downstream side of the valve are connected to each other by a pipe 5. Further, a senser 12 is provided at the outlet of the solar heat water heater so as to operate relative to the three-way valve 6. In case sunlight is absent, the senser 12 turns a switch ON so that when the temperature of water from the outlet of the water heater 2 is lower than the room temperature, the three-way valve 6 makes an outdoor pipe passage 13 communicate with the faucet 3 while when otherwise, the valve 6 makes a radiator side pipe passage 14 communicate with the faucet 3 to perform a heating operation by radiating heat into the room. The hot water flowing through the radiator 7 falls down into a bathtub and in this case, when the temperature of the hot water in the bathtub is low, it is additionally heated by a boiler 11.

Title: Power source
Inventor: NAKANO KATSUAKI
IPC: H02M3/28
Filed: 1982-09-29
Abstract: PURPOSE:To improve the conversion efficiency of a power source by supplying the control voltage of a voltage controlled oscillator as a drive power source to a drive circuit, thereby eliminating the overdrive or insufficient drive of a power transistor. CONSTITUTION:The collector current of a drive transistor 3, i.e., the primary current of a drive transformer 4 is supplied through a resistor 15 from the output point of an error amplifier 13. When the output voltage or current increases, the control voltage from the amplifier 13 decreases, and the oscillating frequency of the oscillator 1 rises. Thus, the ON and OFF frequency of the power transistor 5 increases to act in a direction for decreasing the output voltage, thereby maintaining the output voltage or current constant. Since the collector current of the transistor 3 is supplied from the output of the amplifier 13, the overdrive and the insufficient drive of the transistor 5 can be prevented.

Abstract: PURPOSE:To obtain the mixed output signal of first and second input signals from the emitter of a buffer transistor by connecting first and second differential amplifiers of emitter-common, a current source, and the buffer transistor as in prescribed configuration. CONSTITUTION:When a bias voltage is applied so as to set the first and second differential amplifiers 9, 12 in a balanced state, a current i0 is shown as i0 = i1 + i2, = i3 + i4, = i2 + i4, = i1 + i3. Arithmetic processing is performed, and the output voltage vo of an output terminal 19 goes to v0 = v1 - v2 + v3, thereby, the AC output signal of the sum of the input AC signals of the first differential amplifier 9 and the second differential amplifier 12 can be obtained. The second differential amplifier 12 comprises a voltage-follower circuit with the buffer transistor 16, and a DC component of 100% is fed back to the base of a transistor 14. Therefore, the DC voltage of the output terminal 19 becomes equal to that of the signal v3.
