Abstract: A dehumidification forward passage is provided for guiding air withdrawn from a treating chamber as dehumidification-subject air A? to an adsorption area of an adsorption/desorption type dehumidifying device. A dehumidification return passage is provided for guiding air A? past through the adsorption area to the treating chamber. A desorption heat pump is provided for heating desorbing air HA to be flown through a desorption area of adsorption/desorption type dehumidifying device, with utilizing, as a heat sink, dehumidified air A? which has flown through the adsorption area and sent to the dehumidification return passage. There is provided a sensible-heat heat exchanger configured to cool the dehumidification-subject air A? present in the dehumidification forward passage through a heat exchange reaction with dehumidified air A? present in the dehumidification return passage which has been cooled via absorption of its heat by the desorption heat pump.

Abstract: A semiconductor integrated circuit which effects the subtle control of the well or substrate potential of a circuit in accordance with the operating frequency, the signal multiplication rate from a PLL circuit, the source voltage or the operating state of the circuit, thereby adjusting the operating speed of the circuit and reducing the consumption of electricity.

Abstract: A rack and pinion type steering apparatus in accordance with the present invention is provided with a rack guide made of synthetic resin. On the outer periphery of the rack guide is disposed a taper-form rib extending from the topmost portion of both outer sides of a concave one end-surface toward the portion of both outer sides of the other end-surface of the axial direction. The width of the rib becomes greater as it goes from the other end-surface of the axial direction toward one end-surface which is engaged with the back surface of the rack shaft. As a result, the concave portion of the one end-surface of the axial direction is hard to shrink inwardly when being molded, thereby the diameter of the one end-surface of the axial direction and that of the other end-surface of the axial direction of the rack guide are substantially the same.
