    摘要： A body fluid excretion volume measurement apparatus for medical application. The apparatus stores body fluid excreted from patients in a body fluid storage tank and measures the resistance value with a resistance sensor. The resistance value depends on the shape of the body fluid storage tank, and if the tank is columnar, the resistance value is monotonically increasing with respect to the depth of body fluid. The output of the resistance sensor is processed by a measurement part and electric measurement of the body fluid volume stored in the body fluid storage tank is performed automatically.

    摘要： A liquidometer composed of a siphon for emitting a sample liquid stored in a reservoir and a liquid level sensor for sensing the level of the sample remained in the reservoir. The siphon further includes a pair of sensors for counting the number of emission thereof, while the liquid level sensor includes two rows of resistive film with a plurality of sensing elements embedded therein. Outside the liquidometer, there are provided a counter connected to the emission sensor, a level calculator connected to the liquid level sensor, and a calculator coupled to both. A gross amount of the sample liquid having been measured for a period of hours is obtained by adding together a count signal from the counter which represents the quantity of the sample liquid fully stored in the reservoir and a signal from the level counter which represents the liquid level of the remaining sample liquid. Moreover, variations in the quantity of the sample for a predetermined period is computed by the calculator in response to its internal clock.

    摘要： A liquid level sensor for detecting a level of an electrolyte where: a pair of resistance films are formed on an insulating substrate: a plurality of electrodes are intermittently mounted on the resistance films in the longitudinal direction; the resistance films are soaked in the electrolyte in the vertical direction along the longitudinal direction; the liquid surface is detected from the variation of the resistance value of the resistance films caused by the short-circuiting of pairs of the electrodes in the electrolyte. The exposed surface of the resistance film is covered by a moisture-resistance film. The result is that undesirable change of resistance value of the resistance film caused by being moistened can be reliably prevented.

    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 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.
