摘要: A current sensor includes a first magnetic core that surrounds a portion of a conductor as a current path and has gaps therein, each of which is defined by adjacent ends spaced from each other by a first distance, a magnetic sensing element placed in at least one of the gaps, and a second magnetic core placed near the surrounded portion of the conductor to divide the conductor into channels. The second magnetic core is spaced from the first magnetic core by a second distance smaller than the first distance. Therefore, a magnetic resistance of the second magnetic core is smaller than that of the first magnetic core in a magnetic circuit formed by the first and second magnetic cores. As a result, a disturbance magnetic field mainly passes through the second magnetic core.

摘要: A receiver of an ultrasonic sensor includes reception elements, each of which has a shape of a flat rectangular plate. The reception elements are arranged one-dimensionally on a plane so that the reception surfaces face the same direction and that the reception elements are aligned with small intervals in the width direction thereof while longitudinal ends of the reception elements at a certain side are aligned in a straight line. The widths and the thicknesses of the reception elements are even, while the longitudes of the reception elements are uneven. The both longitudinal ends of the reception elements are fixed to prohibit the vibration of the ends. The longitudes are designed so that the primary resonance frequencies of the reception elements are uneven.

Both end faces in a circumferential direction of the core forms a gap therebetween. A cross-sectional area of the core perpendicular to the circumferential direction gradually increases from the both end faces to a portion opposite to the gap in a diametrical direction. A magnetic sensor is disposed in the gap. Preferably, the core is a stack of a plurality of core plates having different shapes.

摘要: An ultrasonic element has a membrane formed as a thin walled portion of a substrate, on which a piezoelectric vibrator is formed. The piezoelectric vibrator comprises a piezoelectric thin film and metal electrode films, which are formed into a sandwiched structure. The piezoelectric vibrator resonates with the membrane at a predetermined ultrasonic wave-band frequency. A hollow-out pattern is formed in the piezoelectric thin film to divide the piezoelectric vibrator into multiple portions, wherein the hollow-out pattern is formed in such an area corresponding to stress concentrated area which appears in vibrations of the membrane in diametrical directions thereof. The membrane is made to be easily deformed in response to vibration of the piezoelectric vibrator, so that an ultrasound of a higher sound pressure can be emitted.
