摘要： An ink jet application device comprises an application head, an information storage, a first converter, a second converter, a third converter, a three-terminal regulator and a switching circuit. The application head has a plurality of nozzles and a plurality of actuators respectively mounted to the nozzles, and sprays ink from a nozzle by applying a voltage to an actuator. The information storage stores a specific volume of an ink-droplet, characteristic information for relating a volume of the ink-droplet to a voltage value to be applied to the actuator, and setting information for relating a voltage value to be applied to the actuator to a DA setting value. The first converter obtains a volume of the ink-droplet sprayed from a nozzle which is a voltage correcting object, calculates a voltage value related to the volume of the ink-droplet with reference to the characteristic information, and calculates a voltage difference value between the calculated voltage value and a voltage value related to a specific volume of the ink-droplet. The second converter converts the voltage difference value into a DA setting value with reference to the setting information. The third converter converts the DA setting value into an analog signal. The three-terminal regulator outputs a correction voltage when the analog signal is input thereto as a reference voltage. The switching circuit supplies the correction voltage to the actuator mounted to the nozzle which is the voltage correcting object.

摘要： A transmission probe and a reception probe for transmitting and receiving a wideband ultrasonic wave are provided. Each time when the locations of the probes and are moved, a received wave Gj(t) is obtained. Based on a spectrum Fj(f) corresponding to the received wave Gj(t), a narrowband spectrum FAj(f) is extracted. A component wave GAj(t) corresponding to the narrowband spectrum FAj(f) is found by inverse Fourier transformation. A longitudinal wave primary resonance frequency f1 having a relationship with a thickness W (mm) of an inspection target and a primary resonance frequency fS1 of a transverse wave generated by mode conversion are calculated. A comparative display of the component waves GAj(t) is presented using f1, fS1 and sizing coefficients ns1, ns2, ns3 and ns4 for high precision inspection. Based on the measurement point which shows a wave generation in the comparative screen of the component waves GAj(t), it is determined that there is a flaw Z at a certain position inside the inspection target immediately below a line segment connecting the transmission probe and the reception probe.
