  • Publication number: 20210318346
    Abstract: An automated analyzing apparatus according to one embodiment comprises a barcode reader and a cylindrical lens. The barcode reader emits light toward a barcode attached to at least one of a specimen container storing a test sample, a reagent container storing a reagent to be reacted with the test sample, and a specimen rack housing a plurality of the specimen containers arranged in a line, and reads the barcode on the basis of reflected light of the applied light. The cylindrical lens is placed between at least one of the specimen container, the reagent container, and the specimen rack, and the barcode reader.

  • Patent number: 9209846
    Abstract: A radio communication circuit includes a transmitter that includes a modulator modulates a signal with a first modulation scheme and a power amplifier amplifies the signal modulated with the first modulation scheme and output the amplified signal and transmits the amplified signal, a receiver that includes a demodulator demodulates the signal output from the transmitter with a second modulation scheme that is different from the first modulation scheme, a pre-distortion compensator compensates occurred upon the amplification of the signal, of the signal input to the transmitter, based on the demodulated signal and a power controller controls supply of power to the receiver and the pre-distortion compensator and stop the supply of the power based on an average power level of the signal output from the transmitter and a peak-to-average power ratio that is a ratio of an instantaneous peak power level to the average power level.

  • Patent number: 7911303
    Abstract: A circuit breaker includes a vacuum valve, an electromagnet including a first coil for driving an operating shaft of the vacuum valve toward an opening direction by electromagnetic repulsion, a movable core and a permanent magnet. Further, an operating mechanism is provided which excites the first coil to close the vacuum valve, holds the vacuum valve closed by an attractive force of the permanent magnet and excites the first coil in a direction reverse to an excitation direction in closing operation to open the vacuum valve. In the circuit breaker, together with the first coil, a second coil is disposed which is excited simultaneously with an electromagnetic repulsion coil for a quick opening operation by electromagnetic repulsion is provided in the electromagnet.

  • Patent number: 7899332
    Abstract: An optical communication unit performs a bidirectional information transmission between a circuit device in a fixed housing and a circuit device in a moving housing with an optical signal. The optical communication unit includes a light transmitting unit that transmits the optical signal, a light receiving unit that receives the optical signal from the light transmitting unit, and a light propagation path for propagating the optical signal from the light transmitting unit to the light receiving unit. The light propagation path is disposed inside a hinge part that links the fixed housing and the moving housing in an openable and closable manner.

  • Patent number: 5832623
    Abstract: A dirt drying processing equipment is constructed so that hot air out of a hot-air generator is blown into dirt in a drying reservoir through a hot-air supply pipe having a pointed end opened to the bottom of the drying reservoir, vaporizing water contained in the dirt. Solid matter or evaporation residue of dirt is blown by hot air to a cyclone where it is separated therefrom for disposal.
