摘要： PROBLEM TO BE SOLVED: To simplify a structure, and to surely detect a poor liquid discharge, in a poor liquid discharge detecting device which detects the poor discharge of a liquid from a variation of the light receiving quantity of a light receiving element, being constituted in such a manner that light is emitted from a light emitting element in a direction being orthogonal to the discharging direction of the liquid, and the light is made to face the light receiving element.
SOLUTION: Light which goes to the light receiving side 40 from the light emitting side 30 by passing through a poor liquid discharge detecting region A is provided in a manner to be crossed to the liquid discharging direction n. On the light emitting side, the light emitting element 31 such as a semiconductor laser or an LED, a restricting member 32 such as a collimate lens or a slit which restricts the light beam emitted by the light emitting element, and a second polarizer 33 which is set by tilting the polarizing direction at approximately 45° to the liquid discharging direction when required are provided. On the light receiving side, a polarizer 41 which is set by tilting the polarizing direction at approximately 90° to the polarizing direction on the light emitting side, and the light receiving element 42 such as a photo diode are provided. Then, since the light receiving quantity on the light receiving side changes depending on the presence/absence of the discharged liquid such as ink droplets, the poor discharge of the liquid is detected.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic flowmeter hardly affected by a drift change of a zero-cross voltage and capable of measuring accurately an ultrasonic wave propagation time. SOLUTION: Ultrasonic elements are provided in a flow passage with a fluid flowing therethrough. A prescribed period of driving signal is impressed to the ultrasonic element in a transmission side. The propagation time of an ultrasonic wave in the flow passage is found by detecting a phase difference between a reception signal output from the ultrasonic element in the transmission side and the driving signal. The reception signal is hardly affected by the drift change of the zero-cross voltage, because the reception signal is a waveform having the prescribed period. COPYRIGHT: (C)2007,JPO&INPIT
