Disclosed is a humidity control apparatus which ensures a sufficient dehumidification amount without increasing an area of a gas-liquid contact portion in a dehumidification unit, regardless of the type of liquid absorbent used. The humidity control apparatus includes an absorbent circuit connecting a liquid-based dehumidification module, a recovery module, and a liquid-cooling heat exchanger which cools, with a refrigerant, a liquid absorbent before being used in the liquid-based dehumidification module. A refrigerant-cooling-based dehumidification module is positioned upstream of the liquid-based dehumidification module in a flow direction of target air, and cools and dehumidifies, with the refrigerant, the target air before being dehumidified in the module. The liquid-cooling heat exchanger and the refrigerant-cooling-based dehumidification module are connected to a single refrigerant circuit together with a liquid-heating heat exchanger.

A lens shift mechanismof the projection-type image display deviceincludes a horizontal movable basefor horizontally shifting a projection lens, a vertical movable basefor vertically shifting the projection lens, and a horizontal drive actuatorand a vertical drive actuatorfor driving these bases. Driving forces of these actuatorsare transmitted via respective lead screws() and a pair of lead nuts() meshing with the lead screws to shift the bases. A pair of lead nuts are installed with elastic bodies() applying a pressure such that the pair of lead nuts recede from or approach each other in the axial direction of the lead screw. In this configuration, a delay in the shift operation is removed by reducing a backlash in the lens movement.

A refrigeration system includes a heat source unit, a plurality of utilization units, a height-associated value detection unit and a pressure control unit. The heat source unit has a compressor and a heat source-side heat exchanger that functions as a radiator. Each utilization unit has a pressure reducer and a utilization-side heat exchanger that functions as an evaporator. The height-associated value detection unit detects a height-associated value of each utilization unit. The height associated value of each utilization unit corresponds to a height of the utilization unit. The height of each utilization unit is a vertical distance between the utilization unit and the heat source unit. The pressure control unit determines whether each of the utilization units is in operation or stopped and performs refrigerant pressure control based on the height-associated values of the utilization units that have been determined to be in operation.

The performance and the functionality of a projection-type video display device are improved to expand an application range of the projection-type video display device. The projection-type display device has two optical engines, increases the luminance of a display image, achieves a pseudo high resolution, or displays a three-dimensional image and a wide screen. The two optical engines have an adjusting mechanism to adjust a position on which an image is displayed. The adjusting mechanism has a plurality of mechanisms which adjust relative three-dimensional axis-direction positions between the two optical engines and inclinations of the optical engines with respect to axes. For example, in consideration of cross actions between adjustments, the plurality of adjusting mechanisms are allocated to the optical engines. As a result, the adjustments can be easily performed.

A projection image display apparatus which performs an operation for attaching and detaching a projection lens by one action with a simple mechanism is provided. The projection image display apparatus includes an optical engine which irradiates a display element with light emitted from a light source to form an image, a projection lens which enlarges and projects the image emitted from the optical engine, a lens shift mechanism for adjusting a position of an image to be projected onto a screen, a lens attachment unit for attaching the projection lens to the lens shift mechanism, and a first plate for attaching the projection lens to the lens attachment unit to achieve a locked state, and the attachment of the projection lens to the lens attachment unit and the achievement of the locked state are performed by only rotation of the first plate in a first direction. Also, detachment of the projection lens and release of the locked state are performed by only rotation of the first plate in a second direction opposite to the first direction.

A dehumidification system for a dry clean room includes: a dry chamber supplied with air having a lower humidity than air in the dry clean room; a main dehumidification unit which supplies air to the dry clean room; and a terminal dehumidification unit which processes the air to be supplied from the dry clean room to the dry chamber, thus achieving energy saving and cost reduction for the dehumidification system for the dry clean room.

A liquid crystal projector which prevents deterioration of the aluminum grid inorganic polarizing plate due to dust in the cooling air for cooling the liquid crystal panel module. A shade member along the surface of the inorganic polarizing plate prevents the surface from being directly hit by the cooling wind and thus prevents dust from attaching to the surface of the plate.
