Abstract: To provide a display apparatus that makes it possible to further improve a performance in controlling video presentation according to characteristics of an eyeball of a user. A display apparatus is provided that includes a light source; a processor that performs processing on a distribution of characteristics of an eyeball; a monitoring section that monitors a state of the eyeball; a matching section that performs matching on the distribution of the characteristics of the eyeball and the state of the eyeball; and an irradiator that irradiates a specified position on a retina with video display light emitted by the light source.

Abstract: A cover opener for opening a cover 1a that is rotationally removed from and fixed to a reagent container 1 includes: a rotational drive unit 12 and a cover retainer 17 to retain the cover 1a by becoming engaged with a concave portion 1b provided on an upper portion of the cover 1a. A carrier 16 is driven to rotate as the rotational drive unit rotates, as well as to move in a direction of a rotational axis with respect to the rotational drive unit. Springs 19 and 20, one of which is provided between the rotational drive unit and the cover retainer, and the other between the rotational drive unit and the carrier, bias the rotational drive unit and the cover retainer or the carrier in relative fashion to move away from each other. This enables the cover of the reagent container to be reliably opened.

Abstract: The present invention provides an automatic analyzer including: an analyzing unit that includes an analyzing mechanism and a dispensing reagent cassette storage for storing a reagent cassette for dispensing; a reagent replenishing unit including a replenishing reagent cassette storage for storing in advance a reagent cassette for replenishing to be supplied as the reagent cassette for dispensing; and means for ejecting from the replenishing reagent cassette storage the reagent cassette for replenishing that cannot be supplied as the reagent cassette for dispensing.

Abstract: A heat exchanger used for a refrigerating cycle has a plurality of grooves formed in the inner surface of a pipe thereof in the flowing direction of a refrigerant. At least two types of grooves which differ in width are used. The pipe also has fins which are coated with a hydrophilic paint that is black in color. This design enables the heat exchanger to provide improved performance.

Abstract: The present invention provides an air conditioning apparatus in which a suction air stream drawn in the rotational direction of a propeller fan as it bypasses a baffle board, and a discharge air stream guided by a guide plate in the anti-rotational direction of the propeller fan toward the inner surface of the baffle board flow in the opposite directions and met each other in the air passage in a suction chamber, so that a powerful vortex of air is generated, the power of which is further increased by the curl plate extending so as to surround the center of the vortex. Therefore, a large quantity of water in the water storage recess in the upper surface of the bottom plate is lifted, and the resultant water turns into water droplets, which are then mixed in large quantities in the suction air stream entering the fan, whereby the water can be evaporated speedily.
