摘要： A multi-layer capacitor includes first and second side-surface terminal electrodes alternately arranged on four side surfaces of a capacitor body. First and second major-surface terminal electrodes are arranged on a major surface of the capacitor body. First and second internal electrodes which are opposed to each other within the capacitor body are respectively electrically connected at ends thereof to the first and second side-surface terminal electrodes, and are also respectively electrically connected to the first and second major-surface terminal electrodes through via hole conductors. With this arrangement, the directions of the currents flowing within the multi-layer capacitor are diversified, and the lengths of current-carrying paths are shortened so as to achieve a very low ESL value.

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.
