Abstract:
A flow cell device is incorporated in the sensor unit for surface plasmon resonance (SPR) assay. A box shaped flow cell body has a lower surface, and is disposed in contact of the lower surface with a sensing surface for detecting reaction of sample. Two flow channels are formed in the flow cell body, for flow of the sample. Each of the flow channels include a fluid passageway, formed in the lower surface, for flow of the sample in contact with the sensing surface. Two end cavities are formed in an upper surface of the flow cell body and open therein, to extend from ends of the fluid passageway. The flow channels are arranged adjacent to one another, disposed to extend in a direction of the flow. Fluid passageways of the flow channels are overlapped partially on one another in a flow cell longitudinal direction of the flow cell body.
Abstract:
A time point at which a predetermined period elapses since the start of use of a copying machine as a detection subject after factory shipment or repair is obtained. Pieces of set information, which are combinations of various types of information until the time point is reached are sequentially stored to construct a normal set information group. After the time point is reached, presence of abnormality in the copying machine is determined based on the normal set information group and the various types of information obtained.

Abstract:
A sensor unit includes a dielectric block, a thin film layer and a reference surface. The thin film layer is formed on the upper surface of the dielectric block and the reference surface is coplanar with the upper surface of the dielectric block. The sensor unit is held in a predetermined position. A light beam is caused to enter the dielectric block to impinge upon the interface between the upper surface of the dielectric block and the thin film layer so that total internal reflection conditions are satisfied at the interface. Information on an analyte on the thin film layer is obtained on the basis of the light beam reflected at the interface. Displacement of the interface is measured by measuring displacement of the reference surface and the position of the sensor unit is adjusted according to the displacement of the reference surface.
Abstract:
A selective oxidation layer is formed by alternately growing an AlAs layer and an XAs layer containing a group III element X with a thickness ratio in a range between 97:3 and 99:1 on a plurality of semiconductor layers including an active layer. The selective oxidation layer is selectively oxidized to manufacture a vertical-cavity surface-emitting laser.
Abstract:
A projection image display apparatus is equipped with a light shielding member for partially shielding the illumination light from the illuminating optical system so as to reduce the image brightness in a region where the intensity of the reflected light reflected between the on-light and off-light becomes strong, and making the intensity of the illumination light emitted to the respective mirror elements uneven.
Abstract:
A surface plasmon resonance (SPR) assay apparatus is loaded with a sensor unit. The sensor unit has a sensing surface and a flow channel, which has an entrance end opening and an exit end opening, and causes analyte fluid introduced through the entrance end opening to flow on the sensing surface. An optical assay unit assays reaction of the analyte fluid on the sensing surface by detecting attenuation of the illuminated light reflected by a thin film/dielectric interface. A fluid dispenser introduces the analyte fluid to the entrance end opening by pipetting. A fluid collecting vessel stores the analyte fluid used and exited from the exit end opening. A drain conduit extends from the exit end opening toward the fluid collecting vessel, for passage of the used analyte fluid. A suction pump drains the used analyte fluid into the fluid collecting vessel through the drain conduit.
