  • Patent number: 9945880
    Abstract: According to one embodiment, an automatic analyzer includes a magnetic field generator, a photometric unit, a measurement unit, and a decision unit. The magnetic field generator causes magnetic separation in a reaction liquid stored in a cuvette by magnetic particles. The photometric unit includes a light source unit configured to generate light, and a detection unit configured to detect the light generated by the light source unit and generate an output signal corresponding to the detected light. The measurement unit measures a measurement item based on the output signal. The decision unit decides the use range of the output signal to be used to measure the measurement item in accordance with spatial unevenness of the magnetic separation by the magnetic field generator.

  • Patent number: 7063423
    Abstract: A light source lamp unit (10) includes a light source lamp (11), an ellipsoidal reflector (12) and a plate body (19). The plate body (19) is provided behind the reflector (12) with a gap kept therebetween, which has a shape corresponding to the profile of a reflecting portion (122) of the reflector (12). A cooling channel for passing a cooling air is formed between the plate body (19) and the reflector (12). The width of the cooling channel in a direction along an optical axis of the light source lamp (11) is minimized at a part near a neck portion (121) of the reflecting portion (122) and enlarged toward the peripheral edge of the reflecting portion (122) of the reflector (12).

  • Patent number: 4593535
    Abstract: A pressure differential valve connected to a refrigerating circuit piping which, when a refrigerating cycle stops, blocks the high pressure coolant from diffusing into the low pressure section. Said pressure differential valve comprises a valve body having a first inlet, a first outlet, a second inlet and a second outlet; a valve disk installed in a valve chamber between the first inlet and the first outlet to open or close the passage between the first inlet and outlet, the valve disk being urged to open by a spring; a diaphragm installed between the second inlet and the second outlet to form pressure chambers; and a check valve secured to the diaphragm and communicating to both of the pressure chambers; whereby when the check valve is closed, the diaphragm causes, through a connecting rod, the valve disk to close. Said valve disk has radially projecting guide vanes attached to the axially extending portion of the seat-contacting disk to form spaces through which coolant can flow.
