摘要： An infrared gas detector includes an infrared light source emitting infrared light of a specific wavelength, an infrared sensor detecting the infrared light from the infrared light source, and a gas cell accommodating the infrared light source and the infrared sensor. The infrared light source contains an LED or a semiconductor laser. Since the wavelength of the infrared light from the infrared light source is specific, the energy efficiency is high. The LED and the semiconductor laser are small devices, and therefore, the infrared light source and the infrared sensor are easily accommodated in the same small package.

摘要： A fluid sensor detects property of fluid by dipping the sensor in the fluid. The sensor includes: a semiconductor substrate; and a comb-teeth electrode made of a first diffusion layer and disposed on a first surface of the substrate. Although the comb-teeth electrode is capable of directly contacting the fluid without a protection film, corrosion resistance of the sensor against the fluid is improved. Further, since the sensor has no protection film, the sensor can detect the property accurately.

摘要： In a PWM communication system, a sensor unit transmits as reference pulses transmission signals, which exhibit duty cycles of 100% and 0%, respectively, prior to transmission of a transmission signal, which has data items compressed thereinto by a signal processing circuit. An input capture circuit of an ECU measures the duty time and the PWM cycle of the transmission signal according to a timer clock of a timer circuit. A signal processing circuit of the ECU produces a duty cycle correction factor k based on the measured duty times and PWM cycles of the reference pulses, produces receiving data based on the duty time and the PWM cycle of the transmission signal, and the duty cycle correction factor, and separates the receiving data into sensor output values of a pressure sensor and a temperature sensor.

摘要： A peak voltage detector circuit detects a peak voltage of an input voltage. The input voltage is input into a first input terminal of a comparator. A counter circuit counts up a counter value in synchronization with a first clock signal, when a signal output from the comparator is in a first state. The counter circuit counts down the counter value in synchronization with a second clock signal. A digital-analog conversion circuit outputs an output voltage corresponding to the counter value, and the output voltage is input into a second input terminal of the comparator. The first clock signal has a wave period shorter than that of the second clock signal.

摘要： An N-type epitaxial layer is formed on a p-type silicon substrate. Four N+ regions (diffusion regions used as electrodes) are formed in the N-type epitaxial layer. An insulation layer having a fixed depth is formed around each of the N+ regions on a principal surface of an epitaxial layer. The insulation layer restricts a current path region formed between the N+ regions. Side surfaces of the N+ regions are covered by the insulation layer. The N+ regions are brought into contact with the epitaxial layer by a bottom surface exposed from the insulation layer.

摘要： Detecting the rotational direction of a rotor is feasible by allowing a constant current source to supply a constant current flowing from an electric potential supply line to the earth in response to a turning-on action of a switch. Accordingly, detecting both the rotational speed and the rotational direction of the rotor is feasible by using three wiring cables of a power source line, an earth line, and a signal line outputting a pulse signal in accordance with the rotation of the gear. Using such a one-stage voltage adjustment enables the detection signal processing circuit to reduce electric power consumption compared with a system requiring a two-stage voltage adjustment.

摘要： Physical quantity detection equipment includes a detector, an amplifier, an offset adjustment device, an addition device, and an output device. The detector outputs the first voltage corresponding to the detected physical quantity. The amplifier amplifies the first voltage. The offset adjustment device determines a measurement range of the amplified first voltage and outputs a second voltage corresponding to the determined measurement range. The addition device subtracts the second voltage from the amplified first voltage. The output device outputs the subtracted amplified first voltage and informs the determined measurement range. The equipment has only one sensing unit for detecting both a large and a fine change in physical quantity.
