    摘要： A photoelectric sensor is adapted for use in specific applications which require the additional attachment of a circular polarizer. A piece of circular polarizer material is general disc-shaped with two planar surfaces and a peripheral circular surface. The outer periphery of the disc-shaped circular polarizer is encapsulated within a generally annular molded rim. The molded rim is provided with a protrusion that is generally circular and extends from one of the generally flat surfaces of the rim material. The protrusion facilitates the attachment of the rim to the operative face of a photoelectric sensor through the process of ultrasonic welding. Advantages achieved by this device include the facilitated attachment of the circular polarizer to a photoelectric sensor, the protection of the outer peripheral edges of the laminations of the circular polarizer and the avoidance of distortions of the circular polarizer during the manufacturing process.

    摘要： Methods and kits for measurement of concentration of FK778 in a biological sample by means of an immunoassay, preferably a competitive immunoassay. In one aspect, the method and kit involve the use of (a) an antibody to FK778 conjugated to a label, e.g., an acridinium label, (b) an antibody to FK778 not conjugated to a label, (c) a solid phase containing an antibody to a first hapten, e.g., a fluorescein hapten, and (d) a bihapten comprising a first hapten and FK778 or an analogue of FK778, e.g., a bihapten comprising a fluorescein hapten and a FK778 hapten. In another aspect, the method and kit involve the use of (a) antibody to FK778, (b) a bihapten comprising FK778 or an analogue of FK778 and a first hapten, e.g., a bihapten comprising the fluorescein hapten and the hapten of FK778 or an analogue of FK778, and (c) a pretreatment reagent.
