Title: Chemical heat storaging device
Inventor: YANATORI MICHIO
IPC: F28D20/00
Filed: 1984-11-02
Abstract: PURPOSE:To remarkably reduce the heat resistance and enhance fast-heating property by a method wherein a vessel, in which heat transfer medium is housed, is provided in order to feed the heat transfer medium from the vessel, only when the heat-exchange is necessary. CONSTITUTION:Firstly, the evolution of heat starts by introducing substance 8 to be reacted in a second vessel 2, which is vaporized by opening a valve 4, into a first vessel 1 in order to react with reacting substance 7. Secondly, the valve 4 is closed and a valve 11 is open in order for heat transfer medium 14 heated with a heater 13 to enter the first vessel 1. Thirdly, after the predetermined amount of the heat transfer medium 14 is introduced in the first vessel 1, the valve 11 is closed. The heat transfer medium 14 boils by being given the heat generated by the reacting substance 7 and the vapor of the heat transfer medium generated by boiling liquefies itself at a heat exchanger 5, resulting in giving off the heat of condensation, which is transmitted through the heat exchanger 5 to the heat transfer medium flowing in the heat exchanger 5 in order to be used for hot water supply and space heating. When the input to the heater 13 is stopped and a third vessel 12 cools itself down, the vapor pressure in the third vessel 12 lowers, resulting in flowing the heat transfer medium 13 in the third vessel 12 by opening the valve 11.

Title: Low pressure electric-discharge lamp
Inventor: OGISHI KAZUHISA
IPC: H01J61/74
Filed: 1984-11-05
Abstract: PURPOSE:To prevent any luminance nonuniformity as well as reductions in the optical output of the entire emitter tube by making an amount of an alkali metal corresponding to the reduction in the pressure of alkali metal vapor existing around the positive electrode to be discharged from an alkali metal alloy installed near the positive electrode when said pressure starts to decrease. CONSTITUTION:When the lamp of this invention is lit by direct current for example, sodium charged in an emitter tube 3 makes positive ions which are then gradually drawn toward a negative electrode 6. As the result, the amount of sodium existing around a positive electrode 5 notably decreases and the pressure of sodium vapor existing around the positive electrode 5 starts to decrease. When the pressure of sodium vapor existing around the positive electrode 5 starts to decrease, an amount of sodium corresponding to the decrease is discharged from a sodium alloy 7 installed near the positive electrode 5 and therefore sodium is supplied near the positive electrode 5. Owing to the above structure, apparently sodium vapor is almost homogeneously distributed in the emitter tube 3 thereby preventing any reductions or nonuniformity of luminance. Consequently, light is homogeneously emitted from the entire emitter tube 3.
