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.

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 temperature sensor includes a capacitor having electrodes between which a dielectric body having its dielectric constant variable depending on the variations of ambient temperature is interposed, and a CR oscillating circuit utilizing the capacitor. The dielectric body is made of a ceramic dielectric material which has a working temperature range in the normal dielectric phase with the dielectric constant thereof having a temperature coefficient ranged between -1,000 ppm/.degree.C. and -10,000 ppm/.degree.C. The ceramic dielectric body is also used as a substrate on which the CR oscillating circuit is formed.

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.
摘要翻译：帧和语音解码器部分输出错误信息。错误率监视部分基于错误信息来监视误码率。采样率改变部分基于误码率来确定采样率，并且改变差分检测器部分中每个移位寄存器的位数以适应采样率。采样时钟选择器部分基于采样率改变部分的判定选择四个不同频率时钟信号中的一个时钟信号，并将所选择的时钟信号作为采样时钟提供给差分检测器部分。差分检测器部分通过DQPSK（差分四边形相移键控）进行解调。由于误差率始终保持在预定范围内，所以获得良好的语音质量。由于采样率不会增加到不必要的高水平，因此可以实现节电并减少电池的消耗。

摘要： A matching circuit and an antenna apparatus which, though small-sized, can be used in a radio apparatus which transmits and receives radio waves having a wide range of frequencies. A matching circuit includes an inductance element formed of a chip inductor connected in series with an antenna body, a first capacitance element formed of a trimmer capacitor, and a second capacitance element formed of a chip capacitor, which capacitance elements are connected between respective ends of the inductance element and a ground terminal, and thus in parallel to the antenna body. One end of the inductance element is connected to the power supply terminal of the antenna body, and the other end is connected to a power source for applying a voltage to the antenna body. The first capacitance element is connected between a ground and the connection point of the power supply terminal of the antenna body and the inductance element. The second capacitance element is connected between a ground and the connection point of the inductance element and the power source.
