    摘要： There is provided a pulse detecting device which resists fluctuations in the quality by locating an ultrasound transmitting piezoelectric element and an ultrasound receiving piezoelectric element with high precision. In the pulse detecting device, a detection sensitivity of the pulse is improved. A transmitting piezoelectric element and a receiving piezoelectric element are fixed onto a substrate by electrodes. The transmitting piezoelectric element is excited in response to an inputted drive voltage signal to generate an ultrasound and transmits the generated ultrasound to a living body. The receiving piezoelectric element receives an echo produced by reflecting the ultrasound transmitted into the living body by a blood flow of the living body and converts it into a voltage signal. A processing arithmetic unit compares the frequency of the ultrasound generated by the transmitting piezoelectric element with that of the echo received in the receiving piezoelectric element to thereby detect a pulse.

    摘要： A piezoelectric transducer comprises: a substrate having first and second substrate electrodes forming input and output terminals, and one or more piezoelectric elements for transmitting a supersonic wave to an object to be measured and receiving a reflected wave from the object. The piezoelectric elements are arranged on the substrate and have a first surface electrode connected to the first substrate electrode and a second surface electrode connected to the second substrate electrode via a conductive member. An acoustic matching layer is superposed on the piezoelectric elements for efficiently propagating the supersonic wave on the second surface electrode. The conductive member has a thickness not more than that of the acoustic matching layer and is embedded in the acoustic matching layer.

    摘要： A print head has a reduced power size or increased print speed that can be operated at a lower voltage or higher speed and can maintain high-quality output printing free from thinned portions. During intervals between printing operations while a print paper is being fed, pulses are applied to all print electrodes to maintain a uniform potential difference between each of the print electrodes and a counter electrode so that an electric charge is supplied to the ink meniscus. Consequently, a sufficient Coulomb force to permit ink droplets to be ejected is obtained. Therefore, during printing operations, the supplied energy can be reduced and electric charge on the ink surface can be retained. Hence, ink droplets can be ejected stably without nonuniformities.

    摘要： In an electrostatic acceleration type ink jet recording apparatus, when a voltage is preliminarily applied to ink to adjust the width of ink raises, a dedicated drive circuit has been necessary or dedicated electrodes have been necessary for forming the ink raises. According to a recording apparatus of the present invention, machining such as chamfering or steps is provided to a support body having a slit-like opening portion or, alternatively, a surface treatment such as coating an oil repellent solvent to a portion to be machined. Due to such a constitution, the width of the ink raises in the lateral direction of the opening portions can be made constant without using a method such as an electric driving so that a stable printing of dots is ensured. Further, by increasing the ink raise width in the vicinity of a central portion of the opening portion than at end portions of the opening portion, it becomes possible to prevent the diameter of dots to be printed from becoming non-uniform in the longitudinal direction of the opening portion.

    摘要： In an ink jet recording head for an ink jet recording apparatus, insulating members are arranged between adjacent ones of a plurality of recording electrodes so that electric discharge is made less likely to occur across the recording electrodes. Thus, even where the density of the recording electrodes in the head is set high in order to achieve high resolution, ink can be stably jetted. Further, the ink can be supplied to the front end of the head without increasing a static pressure which acts on the ink in such a manner that the insulating members are disposed only in the vicinities of the front ends of the recording electrodes while the discharge withstand voltage across the adjacent recording electrodes is increased.
