摘要： A fluid device includes: a flow path through which a fluid flows; a pressure chamber spaced apart from the flow path in a first direction (Y direction) orthogonal to a flowing direction of the fluid in the flow path; a communication path that is formed along the Y direction and that communicates the flow path with the pressure chamber; and an ultrasonic wave transmitter configured to transmit ultrasonic waves to the fluid in the pressure chamber to generate a standing wave along the Y direction in the flow path.

摘要： A fibrous body accumulating device includes an accumulating section including a drum that introduces and releases a material including fibers, a detection section detecting a presence of the material in the drum, and an estimation section estimating an amount of the material in the drum based on a detection frequency at which the detection section detects the material. The fibrous body accumulating device further includes a storage section in which a calibration curve showing a relationship between the detection frequency and the amount of the material in the drum is stored, and the estimation section calculates information on the detection frequency and estimates the amount of the material in the drum with reference to the calibration curve.

摘要： An ultrasonic measurement device includes an ultrasonic transceiver transmitting an ultrasonic wave and receiving a reflected wave from a target so as to output a reception signal, a scanner moving a transmission/reception position where the ultrasonic transceiver transmits and receives the ultrasonic wave along a first direction, and a position measurer measuring a position of the target. When the position measurer detects a plurality of reception signals corresponding to a plurality of reflection components caused by a difference in distances from the target at a first transmission/reception position in the first direction, the position measurer selects the reception signal based on a ratio between a voltage of the reception signals at a comparison transmission/reception position different from the first transmission/reception position and a voltage of the reception signals at the first transmission/reception position, and measures the position of the target based on the selected reception signal.

摘要： An ultrasonic device includes nine ultrasonic array units arranged in a grid pattern of three rows and three columns, nine drive bypass wires that input and output drive signals to and from the respective ultrasonic array units, a first common bypass wire to which a common potential is applied, coupled to the eight ultrasonic array units, a second common bypass wire coupled to the ultrasonic array unit to which the first common bypass wire is not coupled, and a third common bypass wire coupling the first and the second common bypass wires. One of the drive bypass wires, the first common bypass wire, and the second common bypass wire is placed between the ultrasonic array units placed adjacent to each other. The third common bypass wire is placed inside of the ultrasonic array unit placed adjacent to the ultrasonic array unit coupled to the second common bypass wire.

摘要： An ultrasonic wave measuring device including an ultrasonic wave device and a processor. The ultrasonic wave device transmits transmission ultrasonic waves toward an object, receives reflected ultrasonic waves, and outputs reception signals. The processor is configured to: detect a transmission time; detect zero-crossing points of the reception signals; detect zero-crossing times; calculate periods of time between the transmission time and each of the zero-crossing times; compare a reference period of time with each of the calculated periods of time so as to generate difference values therebetween; determine a minimum value among the difference values; and set a corresponding zero-crossing point having the minimum value as a reception zero-crossing point. The ultrasonic wave measuring device is configured to measure a distance toward the object based on the period of time between the zero-crossing time corresponding to the reception zero-crossing point and the transmission time.
