Abstract: A method of operating an adsorption refrigerator comprising two adsorption columns each housing therein a solid adsorbent and heat transfer tubes and sealed with a refrigerant, a condenser, an evaporator, paths for refrigerant connnecting the adsorption columns to the condenser and evaporator so that the refrigerant may be circulated through the columns, and a pipeline equipped with a valve connecting directly the adsorption columns, which method comprises changing over the adsorption columns periodically alternately between adsorption and desorption phases in manner that the one and the other adsorption columns are at opposite phases and that a heat transfer medium on a heat source side and a coolant are routed through alternately in response to desorption and adsorption phases, respectively.

Abstract: An adsorption thermal storage apparatus formed of an evacuated vessel comprising therein a refrigerant, and an adsorbent heating or cooling section and a refrigerant condensing or evaporating section located in communication with each other, the former section including an adsorbent and finned heat transfer tubes, the latter section including heat transfer tubes placed in dishes. An adsorption thermal storage system comprising the aforesaid apparatus; a heat source (e.g. a condenser of a compression refrigerator) for adsorbent heating; a cold source (e.g. an evaporator) for refrigerant condensation; an exothermic heat source (e.g. cooling tower); an endothermic heat source (e.g. air cooling coil); and a utilization equipment (e.g.

Abstract: The present invention relates to a packed battery unifying a plurality of battery cells housed in a case. The case comprises a tubular body housing the battery cells and a couple of lids closing both the end openings of the tubular body respectively, thus being arranged in a three-unit construction. This arrangement allows the case to be completely sealed off by ultrasonic wave welding.

Abstract: An adsorption refrigeration system comprising adsorption columns housing a solid adsorbent and heat transfer tubes and sealed with a refrigerant, an evaporator, a condenser, and pipe lines connecting them together so that the refrigerant may be circulated, the pipe lines being equipped with valves, preferably, butterfly valves, capable of opening or closing by means of internal pressure difference between the evaporator side and condenser side and driving force of eccentric valve shafts. The system is operated by alternatively changing over adsorption and desorption stages between the one adsorption column(s) and the other column(s) so that both columns may be at mutually reverse stages; shortly before change-over, transferring whole amount of heat remained in the one column(s) immediately before shifting from desorption to adsorption stage to the other column(s) immediately before shifting from adsorption to desorption stage where the preheat the adsorbent and then reversing the stages.

Abstract: The present invention relates to a sealed type battery provided with a safety valve and a method of manufacturing the same, the sealed type battery of the present invention has a mouth-sealing plate, provided with the safety valve, serving as a terminal of one polarity, being arranged through an insulating member in a hole of a metallic cover closing an opened portion of an exterior can serving as a terminal of the other polarity, and an extension of a hole edge of the metallic cover being cramped to the insulating member to fix said mouth-sealing plate, whereby the cramping diameter can be reduced in comparison with that of the conventional battery, and as a result, the high hermeticity can be given to the battery and the electrolyte can be completely prevented from leaking.
