  • Patent number: 11933804
    Abstract: In a case where a dispensing tip is imaged from below, liquid attached to the tip falls downward and contaminates an imaging mechanism. An automatic analyzer includes: a buffer that has a hole for holding a tip for dispensing, the hole passing through the tip; a probe for dispensing having a tip to which the tip is attached; an imaging unit that images the tip; and a controller that controls the tip such that the tip is mounted on the probe by pressing the probe against the tip that passes through the hole to be held by the buffer, in which the imaging unit is disposed to image the tip from an upper side to a lower side in a gravity direction.

  • Patent number: 11231346
    Abstract: A lower-side structure forms a specimen chamber in which a specimen base is provided. An upper-side structure forms a nozzle chamber above the specimen chamber. The specimen chamber and the nozzle chamber are separated by a gate valve. In the nozzle chamber, at least a tip opening of a nozzle that ejects a specimen is present. A control device maintains a relationship of gas pressures such that a gas pressure in the specimen chamber is higher than a gas pressure in the nozzle chamber when the lower-side structure and the upper-side structure are in communication with each other.

  • Patent number: 11114914
    Abstract: A motor includes a stator core, a first coil, and a second coil provided adjacent to the first coil in the radial direction. The first coil and the second coil do not coincide in position with each other as seen in the axial direction of the stator core. A first coil end portion of the first coil and a second coil end portion of the second coil respectively include a first facing portion and a second facing portion facing each other in the radial direction. The motor further includes an out-slot insulator interposed at least between the first facing portion and the second facing portion and provided so that at least a part of the first coil end portion and the second coil end portion is exposed.

  • Publication number: 20120164939
    Abstract: A repeater equipment 10 according to the present invention includes a receiving unit 12 configured to receive broadcast information transmitted by the radio base station, and a control unit 13 configured to change a frequency band targeted for amplification of the radio signal, adaptively based on the broadcast information. Frequency range information contained in the broadcast information includes a combination of a center frequency and a bandwidth of each of one or more of frequency bands. The control unit 13 adaptively changes the frequency band targeted for amplification of the radio signal by amplifying a radio signal within a frequency band currently in use and decreasing an amplification gain for a radio signal within a frequency band currently not in use, based on the frequency range information.

  • Patent number: 4901044
    Abstract: A quarter-wave distributed-constant dielectric filter or resonator having a ceramic body which typically is composed principally of barium titanate. The ceramic filter body has one or more resonance holes extending therethrough. A conductive covering of silver or the like on the filter body has a portion formed on the surface defining each resonance hole. Mounted in each resonance hole is a prefabricated capacitor having a first terminal extending from within the resonance hole. The second terminal is electrically coupled to the conductive covering on the surface of the resonance hole. The capacitance of the capacitor or capacitors can be known before they are mounted to the filter body, so that the filter is readily manufacturable to exact electrical characteristics desired.

  • Patent number: 4746511
    Abstract: A lipopolysaccharide characterized by a polysaccharide portion composed of D-arabinose and D-mannose in a 1:3/4 ration and 37 to 47% of a fatty acid portion having 14-19 carbon atoms bonded to the polysaccharide through an ester linkage. This lipopolysaccharide has physiological activities such as antitumor activity, immunizing activity, cell juvenescent activity, phagocyte activating activity, and infection preventing activity.This lipopolysaccharide is prepared by culturing a Mycobacterium or a Propionibacterium and extracting the lipopolysaccharide from the culture with a non-ionic surface active agent and purifying the extract with a molecular sieve.
