Title: On-load tap changer
Inventor: TONEGAWA AKIRA
IPC: H01F29/04
Filed: 1984-03-10
Abstract: PURPOSE:To make it possible to ensure the judgment of the symptom and place of a fault in a short time, by performing the judgment when the abnormality or the degree of the abnormality is detected at every sound, which is generated by a driving system, a tap selector or switches. CONSTITUTION:When a switching signal is outputted from a switching signal generating part 1, a motor in a motor operating mechanism 2 is started, an on- load tap changer 3 starts operation and a sound is generated. At this time, a switching detecting part 4 detects the switching signal outputted from the switching signal generating part 1 and transmits the detected signal to an abnormality judging part 6. A sound detecting part 5 detects the sound generated by the on- load tap changer 3 and transmit the signal. As a result, the abnormality judging part 6 compares the generated times and the sound levels with regard to the sound, which is generated when the on-load tap changer 3 changes one tap, and the sound, which is generated, at the time of normal switching and stored in a memory circuit 7. Thus the symptom and the place of the falut are detected and the signals are sent to an display circuit 8.

Title: Power supply circuit
Inventor: OOSAWA MITSUO
IPC: G05F1/56
Filed: 1982-03-23
Abstract: PURPOSE:To obtain the double voltage having the positive and negative absolute values which are exactly equal to each other, by connecting a pair of batteries and two pairs of DC-DC converters, connecting in series the outputs of those two pairs of converters and comparing the middle point of said outputs with an earth potential. CONSTITUTION:A pair of batteries of voltage Vi are connected to DC-DC converters 3A and 3B. When the input voltage Vi is lower than 6V, for example, the voltage Vi emerges directly at a terminal T1. While if the Vi is higher than 6V, the pulse width is modulated 4 for the output of a comparator 5. Then a transistor TRQa is controlled, and the voltage VO is raised up to the reference voltage of 9V, for example. The converter 3B compares 7 the reference voltage with the potential at the joint of resistances r1 and r2 of the same value and modulates 6 the pulse width. The potential of a terminal TO is set at -VO by a TRQb. The difference of potentials is equal to 2VO between terminals T1 and T2. The voltage twice as high as power supply voltage E is applied to a power amplifying part 1 which supplies a signal (e), and therefore an output of 4-fold efficiency is obtained through a speaker SP. Thus it is possible to generate the double voltage and to use together different types of batteries.

Title: Controlling method for heat accumulating system by use of metal hydride
Inventor: UEDA KEISUKE
IPC: F28D20/00
Filed: 1981-03-31
Abstract: PURPOSE:To control the titled heat accumulating system in a simple manner and to transfer reaction heat quickly to a heat exchange fluid by a method wherein a large quantity of hydrogen gas is supplied into the heat accumulating system at the initial stage of reaction and the supply and stoppage of the supply of the hydrogen gas are repeated in an alternative fashion so that the temperature of the heat exchange fluid is maintained within a predetermined range. CONSTITUTION:The flow rate of hydrogen gas is determined by the difference between the pressure in a metallic vessel 2 and the pressure in a hydrogen gas tank 6 and the resistance of a pipe including an orifice 3 and an ON-OFF valve 4. When the ON-OFF valve 4 is opened, the hydrogen gas begins to flow into the vessel 2. In this case, as the above flow rate of the hydrogen gas is determined to have a comparatively high value, the temperature of the heat exchange fluid reaches its uppermost value after a lapse of only a little time from the starting of the reaction of the hydrogen gas. The above temperature is detected by temperature detectors 8 and 9, the detected temperature is compared to a preset value at a control section 10 and the ON-OFF valve 4 is closed by the operation of a controller 11. Thus, the ON-OFF operation of the valve 4 are continued every time when the temperature of the heat exchange fluid rises and falls to reach its upper- and lowermost values to thereby keep the temperature within a target temperature zone.
