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.

A magnetic sensor unit includes an elongated nonmagnetic sensor case, magnets, magnetic sensors, and positioning portions. The sensor case has a plurality of sensor housing recesses formed in a row in its upper surface in its longitudinal direction, and magnet housing recesses formed in a row in its lower surface at positions respectively corresponding to the sensor housing recesses. At least the upper surface of the sensor case is covered with a nonmagnetic cover. The magnets are respectively housed in the magnet housing recesses of the sensor case. The magnetic sensors are respectively housed in the sensor housing recesses of the sensor case and have magnetoelectric transducers magnetically biased by the magnets. The positioning portions are respectively formed in the sensor housing recesses of the sensor case and respectively position the magnetic sensors in a longitudinal direction thereof and a direction perpendicular thereto.
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.

An LC composite component employing a ceramic sintered body obtained by laminating pluralities of magnetic green sheets and dielectric green sheets and cofiring the same. The ceramic sintered body is provided therein with a magnetic region and a dielectric region along the direction of thickness. The magnetic region of the sintered body is provided with at least one inner electrode layer which extends to first opposite side surfaces of the sintered body, thereby to define an inductance unit. The dielectric region is provided with a plurality of electrodes oppositely arranged through the dielectric substance, which plurality of electrodes includes first and second electrodes. A pair of first outer electrodes are formed on the first side surfaces of the sintered body, to be electrically connected with the inner electrode formed in the magnetic region. The first electrode in the dielectric region is electrically connected with at least one of the first outer electrodes, and the second electrodes is connected with a second outer electrode which is formed on another surface of the sintered body.

A dry/dew/frost sensor comprising a plurality of sensor units, each sensor unit comprising a ceramic substrate (1, 2) whose permittivity is lower than ice and a pair of electrodes (3, 4; 5, 6) being arranged on the ceramic substrate in contact therewith, wherein adjacent sensor units are arranged so as to face each other at a predetermined distance so that the pair of electrodes (3, 4; 5, 6) may be opposed to each other, and the impedance between the pair of electrodes on each of the sensor unit varying with changes in three states, dry, bedewed, and frosted states.
摘要:
A humidity sensitive device, including opposing electrodes formed on an insulating substrate, and a humidity sensitive film formed on the surface of the insulating substrate and at least between the opposing electrodes. The humidity sensitive film is obtained by coating on the surface of the insulating substrate a uniformly dispersed mixture including zirconium oxychloride and epoxy resin and heating the same.
