摘要： A detection voltage output circuit of a charge generation type sensing device outputs the charges generated on the sensing device in the form of a voltage. The detection voltage output circuit comprises: a sensing device composed of a dielectric for generating charges in accordance with a change in a physical quantity applied from the outside; a capacitor at a first stage which is connected in parallel to the sensing device and stores the charges generated on the sensing device; a capacitor at a second stage which stores the charges transferred from the capacitor at the first stage; a transfer switch which is provided between the capacitor at the first stage and the capacitor at the second stage so as to transfer the charges stored in the capacitor at the first stage to the capacitor at the second stage; an operational amplifier which is connected to the capacitor at the second stage so as to convert the charges stored in the capacitor at the second stage into a voltage and outputting the thus-obtained voltage; and an output switch which is connected to the output side of the operational amplifier so as to be turned off while at least a part of the charges stored in the capacitor at the first stage are transferred to the capacitor at the second stage and turned on after the transfer switch is turned off to output the voltage from the operational amplifier. The charges generated on the sensing device are output in the form of a voltage.

摘要： A surface accoustic wave device includes a substrate which is made up of single-crystalline dielectric member and a piezoelectric thin film epitaxially grown thereon. An aluminum electrode defining an interdigital electrode is formed along the interface between the dielectric member and the piezoelectric thin film. This aluminum electrode is formed of an aluminum film which is crystallographically oriented in a constant direction, whereby stressmigration of the aluminum electrode is suppressed, while enabling epitaxial growth of the piezoelectric thin film over the entire surface insert.

摘要： In a frost and dew sensor composed of two thermosensitive resistors, a power source and an arithmetic circuit, frost or dew is detected from the change of a differential temperature between the two thermosensitive resistors as two different currents from the power source are supplied to the respective thermosensitive resistors. In an alternative form, the sensor has a single thermosensitive resistor, which is energized as two different currents are alternately supplied from the power source so that frost or dew is detected by comparison of the time-lags between the two outputs from the thermosensitive resistor.

摘要： A pyroelectric sensor senses the infrared rays radiated from the human body and outputs the detected infrared rays as an electric signal. It detects the trespass of somebody on a room and is used for the prevention of crimes and the like. The pyroelectric sensor includes a substrate, an element-pair disposed on the surface of the substrate and an amplification circuit for amplifying the current signals output from the element-pair. The substrate is composed of a material having a thermal conductivity as low as not more than 0.04 cal/cm sec.degree. C. so as to prevent the heat from being released through the substrate. A hole is formed in the substrate. The amplification circuit amplifies the current signals of the element-pair, thereby dispensing with the impedance transformation which is inevitable in the prior art. Thus, the sensitivity of detection is improved and the manufacture of the sensor is facilitated.

摘要： A method of mounting electrodes on a sensor chip and coating the sensor chip for insulation. Small through holes corresponding to the connecting terminals of a sensor chip for connecting the sensor chip to external elements and electrode patterns serving as lead frames are continuously provided for respective sensors in the longitudinal direction on a sheet-like tape carrier composed of a protective insulation material. The sensor chips are mounted on the tape carrier and the terminals of the sensor chips are connected to the corresponding electrode patterns through the corresponding small through holes, thereby completing the assembly packaging a sensor of a plurality of sensor elements. The thus-obtained sensor elements arranged in alignment and in parallel on the tape carrier are separated from each other and mounted on respective sensor bases and packaged.

摘要： A framing and voice decoder part outputs an error information. An error ratio monitoring part monitors a bit error ratio based on the error information. A sampling rate changing part decides a sampling rate based on the bit error ratio and changes a number of bits of each shift register in the differential detector part to adapt the sampling rate. A sampling clock selector part selects one clock signal among four different frequency clock signals based on the decision of the sampling rate changing part and gives selected clock signal to the differential detector part as a sampling clock. The differential detector part makes demodulation in DQPSK (Differential Quadrilateral Phase Shift Keying). Since the error ratio is always maintained within a predetermined extent, a good voice quality is obtained. Since the sampling rate will not increase to unnecessarily high levels, power saving can be achieved and a consumption of batteries is reduced.

摘要： An opening is formed in a region of a circuit board opposite a vibration region E of a piezoelectric element. The piezoelectric element is mounted to the circuit board, and electrical connections extend between and support the piezoelectric element from the circuit board by a solder. The soldered connection portions are surrounded by a bonding agent. An opening in the circuit board prevents any excess bonding agent from invading the vibration region E of the piezoelectric element, and the bonding agent assists in dispersing stresses exerted on the circuit board thereby minimizing the stresses transferred to the piezoelectric element.
