  • Patent number: 11183403
    Abstract: A semiconductor wafer held by a susceptor in a chamber is irradiated with halogen light radiated from a plurality of halogen lamps to be heated. A stainless steel block having an opening in a cylindrical shape is provided between the chamber and the halogen lamps. This reduces a distance from a light emitting portion in a light source region in which the plurality of halogen lamps is arranged, throughout the entire circumference of the opening in a cylindrical shape, so that the amount of reflected light from the inner wall surface of the opening toward the peripheral portion of the semiconductor wafer becomes uniform. This causes a uniform increase in illuminance of the peripheral portion of the semiconductor wafer, where temperature tends to decrease, at the time of light irradiation from the halogen lamps, so that in-plane temperature distribution of the semiconductor wafer can be made uniform.

  • Patent number: 11162965
    Abstract: The object of the invention is to avoid a decrease in dispensing accuracy of a sample, a reagent, or the like as a temperature changes. In an automatic analyzer, a dispensing nozzle sucks the sample from a sample container holding the sample and discharges the sample to a reaction container. A syringe pump controls an amount of change in a volume of water. A first pipe connects the dispensing nozzle and the syringe pump. An electromagnetic valve flows or stops the water. A second pipe connects the electromagnetic valve and the syringe pump. A branch pipe branches the water. A third pipe connects the electromagnetic valve and the branch pipe. A case accommodates at least the syringe pump, the first pipe, the electromagnetic valve, the second pipe, the branch pipe, and the third pipe. Further, the third pipe includes a heat exchange unit that performs heat exchange of the water.

  • Patent number: 11103219
    Abstract: An ultrasound diagnostic apparatus includes the following. A deflection controller generates delay time information to make phases of reception signals input to channels uniform according to a deflection angle. A channel selector selects a channel in which the reception signal is turned on or off so that the phases of the reception signals input to channels are different and which generates channel selection information. A reception delay interrupter provides the delay amount to the reception signal and which turns on or off the reception signal. An adder adds the plurality of reception signals which are provided with the delay amount and turned on.

  • Publication number: 20210252890
    Abstract: A printing apparatus includes a conveyance unit to convey a print medium, a belt, a tensioner, and a control unit. The belt transmits a driving force of a drive unit to the conveyance unit. The tensioner is displaceable and makes pressure contact with the belt to generate tension. The control unit controls driving of the drive unit in a state where the tensioner is in pressure contact with the belt. The control unit performs first control in which the drive unit is driven with a first control value, which is not based on a driving amount detected by a detection unit. Where the detection unit detects the driving amount, the control unit subsequently performs second control in which the drive unit is driven with a second control value, which is based on the driving amount detected by the detection unit.
