Abstract: In a range of a wind velocity of 0.5 to 3.5 (m/s) in a refrigeration cycle, when combining absorbent having a small dependency on the wind velocity and the refrigeration cycle, it is not possible to vary dehumidification capability by changing the wind velocity and matching with an actual load is poor. In a refrigerating and air conditioning apparatus having a refrigerator 20 in which refrigerant is put, and having a compressor 20a for compressing the refrigerant, a condenser 20b, and a throttle device 20c, and an evaporator 20d, and a desiccant rotor 1, which is water adsorption means, an adsorbent is supported with the desiccant rotor 1, whose time constant at a water adsorption equilibrium becomes small as a wind velocity increases in the range of the wind velocity of 0.5 to 3.5 m/s, the condenser 20b is disposed upwind of the desiccant rotor 1, and the evaporator 20d is disposed downwind of the desiccant rotor 1.

Abstract: In a method for recycling a double component developer that contains a carrier and a toner used for an image forming device such as office automation equipment, an economic value of recycling is increased, thereby allowing a company to carry out an active and sustainable environmental activity. Material components of a carrier are completely utilized, so that a process of removing and disposing part of components of the carrier, which is present in the conventional technology of a carrier recycling, is omitted from a recycling system, and in consequence, a cost of recycling is minimized. Furthermore, as well as a subject of the recycling, i.e. a carrier itself, a more valuable material, i.e. a platinum group metal, is utilized for the recycling.

Abstract: Heat exchangers 40, 40a, 40b for performing heat exchange between a refrigerant and air include fins 45, 45a, 45b for heat transfer, each of which has fine pores each having a diameter ranging from 1 to 3.5 nm for adsorbing water contained in the air by a capillary condensation phenomenon. Preferably, the fine pores are distributed having a different diameter in accordance with the position of the fins 45, 45a, 45b on the surface.

Abstract: The strain gauge for measuring large strains has metallic foil pattern sections including a gauge element pattern section, gauge tab pattern sections and connecting pattern sections attached to a gauge base. The gauge base having the metallic foil pattern sections attached and connected with the bases of gauge leads is almost entirely covered on the surface with a laminating film, and the tip of the laminating film is extended by a predetermined length from the tip end of the gauge base, to form a protruding portion. The protruding portion functions to prevent the separation of the gauge base from an object to be measured.
