    摘要： A piezoelectric sensor device has a piezoelectric body vibrator consisting of the piezoelectric body which is sandwiched by a pair of electrodes, a power source which applies a voltage to the piezoelectric body vibrator so as to get excited for vibration, means for monitoring electric constants to detect changes in electric constants accompanied by vibration of the piezoelectric body. The change in electric constants in the piezoelectric body is detected as a change in frequency for vibration of the piezoelectric body corresponding to an electric constant under the determined conditions. The piezoelectric sensor device has a means to obtain the frequency value from frequencies at not less than two points giving a determined electric constant. According to the piezoelectric sensor device the dispersion in measured values due to change in vibration aptness of vibration system and the polarization state of piezoelectric body vibrator can be made smaller.

    摘要： A method for detecting the solid particles contained in a fluid, by the use of a particle sensor having a flow path of a fluid, having a fluid inlet and a fluid outlet, and a sensor element provided in the flow path, which comprises (a) a vibrating section having such a mass that is sensitive to the collision of solid particles contained in the fluid, with the vibrating section and (b) a detecting section for detecting the vibration of the vibrating section caused by the collision and converting the vibration to electric signals. The method includes steps of: passing a fluid to be examined, through the particle sensor, selectively detecting, from the electric signals outputted from the particle sensor, an electric signal portion having particular frequencies ranging from 1/50 to 10 times the primary resonance frequency of the sensor element, measuring the maximum amplitude of the electric signal portion, comparing the maximum amplitude measured above, with a given value predetermined with the particle sensor based on (1) the maximum amplitude of a portion of the electric signals caused by the collision of solid particles contained in a fluid, having the above particular frequencies and (2) the maximum amplitude of a portion of the electric signals caused by the turbulent flow of the same fluid containing no solid particles, having the above particular frequencies, and judging, depending upon the result of the above comparison, whether or not the electric signals outputted from the particle sensor with the fluid to be examined have been caused by the collision of solid particles with the particle sensor.

    摘要： A recording head operable to apply an electric current to an electrically resistive layer provided on a recording medium or a planar intermediate member interposed between the medium and the recording head. The head includes an electrically insulating substrate, and at least one recording electrode formed on one of opposite major surfaces of the substrate. The substrate is formed of an electrically insulating material whose wear resistance is lower than that of the recording electrode or electrodes. The substrate has a distal end portion extending from a proximal portion by a predetermined distance from the proximal portion for contact with the electrically resistive layer. The distal end portion has a thickness smaller than that of the proximal portion, as measured in a direction perpendicular to a direction of extension of the distal end portion. At least one return circuit electrode formed from a metal or metal alloy sheet is provided on the other major surface of the substrate remote from the recording electrode(s).
