Abstract: An adsorption core has (i) a heat medium tube in which a heat medium flows and (ii) an adsorption agent that adsorbs a fluid in a vapor phase outside of the heat medium tube when being cooled by the heat medium and desorbs the absorbed fluid when being heated. The heat medium tube has (i) a core member that is made of metal having a higher hardness with respect to copper and (ii) a covering layer that is made of copper and covers an outer surface of the core member. A sintered body of a copper powder and the adsorption agent is provided in a peripheral portion of the heat medium tube. The copper powder and the heat medium tube are metallically coupled with each other. Accordingly, stiffness of the heat medium tube can be higher while improving a heat transfer performance between the heat medium tube and the adsorption agent.

Abstract: An adsorber includes: a heat-medium pipe through which a heat medium flows; an adsorbent layer having an adsorbent that adsorbs a vapor-phase refrigerant located outside the heat-medium pipe by being cooled by the heat medium, and further desorbs the adsorbed refrigerant by being heated; and a heat-transfer member that transfers heat between the heat-medium pipe and the adsorbent. In the adsorber in which the heat-transfer member and the adsorbent are integrally formed, an adsorbent filling ratio ? is set at 70% or less when the adsorbent filling ratio ? is defined as a value obtained by dividing a filling density ? of the adsorbent filled in the adsorbent layer by a true density ?abs of particles of the adsorbent. For example, the adsorber may be suitably used for an adsorption refrigerator.

The sintered member is pressurized on the first face of the board member in a direction of layering the board members. All outer periphery of the second passage is sealed.

Abstract: Disclosed is a structural vibration damping device, which comprises a piezoelectric element adapted to be mounted on a structure, a shunt circuit inserted between two electrodes of the piezoelectric element, and an electric circuit for selectively opening and closing the shunt circuit. In this damping device, the electric circuit is operable, when a voltage between the electrodes of the piezoelectric element has a positive or negative extreme value due to a vibration of the structure, to close the shunt circuit so as to allow a current to flow between the electrodes of the piezoelectric element, and, when the current is reduced to zero, to open the shunt circuit so as to preclude the current flow until a voltage between the electrodes of the piezoelectric element subsequently has the extreme value. Further, each of the shunt circuit and the electric circuit is designed to be operated using only a power generated by the piezoelectric element.
