  • Patent number: 9759694
    Abstract: An analysis method is achieved in which pressure variation resulting from sample injection or passage switching by an autosampler does not exert an influence on the control of a liquid transfer pump. The liquid chromatograph analysis method comprises the steps of: transferring two or more types of eluents while changing a mixing ratio between the eluents; adjusting an amount of the transferred liquid within a predetermined time in a passage for the eluent transferred; injecting a sample in the passage; supplying to a separation column the eluent into which the sample is injected; separating a target component in the sample; and detecting the target component thus separated. In this method, control is exercised so as to synchronize a liquid transfer cycle of the eluent with the sample injecting operation and to implement the sample injecting operation at a timing rather than the pressure obtaining time.

  • Patent number: 9753024
    Abstract: An apparatus for determining blood clotting capacity comprises an actuator to cyclically move a member within a sample of blood received in a well in a tray and one of a deflection sensor and a position sensor to determine the position of the wetted member upon being acted upon by the actuator. The theoretical position of the wetted member, as determined using a known actuator force and wetted member physical data, is compared to the sensed deflection or position of the wetted member, and the resistance to movement of the wetted member caused by the blood is determined and correlated to a clotting capacity.

  • Patent number: 9746408
    Abstract: A dust sensor includes a multi-wavelength light source, a receiver, and a controller. The light source emits light of different wavelengths. The receiver generates one or more acoustic wave measurement values based on acoustic waves irradiated from the light source to air particles. The controller controls at least one flickering cycle of the light source, determines the type particles based on the acoustic wave measurement values, and calculates the concentration of particles. The controller calculates the concentration of particles in proportion to an intensity of the acoustic wave measurement values, and determine the type of particles based on the acoustic wave measurement values. The acoustic waves are generated differently based on wavelengths of light emitted from the multi-wavelength light source.

  • Patent number: 9743840
    Abstract: A flash lamp 32 excites a laser rod 31. A Q switch 35 which changes the loss of the optical resonator according to the voltage applied is inserted on the optical path of a pair of mirrors 33 and 34 forming the optical resonator. An optical path shutter 39 is provided on the optical path of laser emission light. In a first operation mode in which laser emission is performed, the optical path shutter 39 is opened and the voltage applied to the Q switch 35 is changed from a high voltage to, for example, 0 V to emit pulsed laser light after the flash lamp 32 excites the laser rod 31. In a second operation mode in which the laser emission is interrupted and waited for, the optical path shutter 39 is closed and the voltage applied to the Q switch 35 is, for example, 0 V.

  • Patent number: 9719835
    Abstract: A ceramic card having a thick film network, with conductive vias formed as part of the card. Each of the vias is in electrical communication with both sides of the thick film network, allowing the pads and the pad senders to be formed on both sides of the card. This configuration maintains the contact when one of the connectors is subjected to bending force or is otherwise displaced, maintaining contact with at least one of the pads, and allowing the system to still function. The double sided thick film network allows for each connector to touch both sides of one of the pads, and still maintain electrical communication with the level sender, thus eliminating the failure mode of intermittent contact with the thick film network resulting from movement of the connector.
