Title: Voltage switching circuit
Inventor: KAKIHARA EISHIN
IPC: H04H40/36
Filed: 1981-11-05
Abstract: PURPOSE:To improve the reliability of a voltage switching circuit without using any mechanical switch, by producing plural pulses of different widths in response to the output of each stage of a register which shifts the output in accordance with the working of a switch and then delivering the DC voltage corresponding to the pulse width. CONSTITUTION:A mode switching contact switch S and a shift register SR having an output producing stage shifting by one every time when the switch S is turned on are provided to a voltage switching circuit. The pulse generators P1, P2 and P3 are connected to the stages of the register SR, and pulse trains of different pulse widths are produced from these pulse generators. These plural pulses are applied to an LPF, and the plural outputs are converted into the DC voltage corresponding to the pulse widths to be applied to a terminal 10 of a demodulating integrated circuit. Thus the reliability is improved with no use of a mechanical switch for a voltage switching circuit which is used to a TV multiplex sound signal receiver.

Title: Heat accumulator
Inventor: NASAKO KENJI
IPC: F28D15/02
Filed: 1984-08-29
Abstract: PURPOSE:To minimize the heat losses and to increase the heat accumulating speed, by housing a metal hydride, heat pipes and a filter in a pressure hydrogen container having a heat insulating material. CONSTITUTION:When heat is to be accumulated, a high-temperature heating medium is admitted from a heating medium inlet conduit 9 into a heat exchange jacket 7. The heat of this heating medium is taken via a heat pipe 5 into a container 1, and is transmitted via heat transmitting fins 6 to a metal hydride 3. As a result, the metal hydride 3 releases hydrogen, and the hydrogen is taken outside via a metal sintered filter 4 in the container, a manifold 11 and a hydrogen inflow/outflow conduit 12 and is stored. On the other hand, when radiation is to be carried out, reversely the hydrogen stored outside is released into the container via the hydrogen inflow/outflow conduit 12, the manifold 11 and the metal sintered filter 4. The heat released when the hydrogen combines with the metal hydride 3 is transmitted from the fins 6 to the heat pipe 5, is recovered by the heating medium flowing through the heat exchange jacket 7 and taken outside via a heating medium outlet conduit 10.
