摘要： This temperature measurement device includes a temperature sensing unit serving as a detector for measuring a magnitude of a heat flow transmitted from a living body, a housing having a hollow structure, a heat flow compensation mechanism with a hollow structure that is disposed in a space inside the housing so as to cover the temperature sensing unit and transports a heat flux from the living body outside the temperature sensing unit to an upper part of the temperature sensing unit, and a circuit board mounted on the heat flow compensation mechanism. The circuit board includes a processing electronic circuit for calculating the internal temperature of the living body on the basis of the magnitude of the heat flow measured by the temperature sensing unit.

摘要： The disclosed apparatus includes a heat meter and a flow meter. The heat meter includes means for delivering trains of pulses to a heat register, the pulses per train being proportional to the temperature difference between fluid inlet and outlet passages of heat exchange means, and the recurrence rate of the pulse trains being determined by a flow sensor. A visual indicator of the pulse trains facilitates zero-difference adjustment of the temperature sensors when they are both at the same temperature. Compensation for variations in the specific heat of the fluid and temperature-related inaccuracy of the flow sensor is effected by non-linear frequency adjustment of an oscillator that generates the pulses. In a flow meter (omitting the temperature-difference circuit) compensation for temperature-related inaccuracy of flow-sensors is effected correspondingly.

摘要： A heat conduction-type sensor corrects (calibrate) effects of a temperature of a measurement target fluid and a type of the fluid on a measurement value in measurement of a flow velocity, a mass flow, or an atmospheric pressure. Also provided is a thermal flow sensor and a thermal barometric sensor with this correcting function, high sensitivity, simple configuration, and low cost. At least two thin films that are thermally separated from a substrate through the same cavity are provided, one thin film comprises a heater and a temperature sensor, and the other thin film comprises at least one temperature sensor, the temperature sensors being thin-film thermocouples. The thin film is arranged in proximity so that it is heated only through the measurement target fluid by heating of the heater. A calibration circuit calculates and compares quantities concerning heat transfer coefficients of a standard fluid and the unknown measurement target fluid.

摘要： A flow-sensing system is provided which employs a pair of sensing resistors. One of the resistors is disposed within flowing fluid, while the other is shielded from the flow. The sensor resistances are held constant by identical feedback circuits which maintain the relationship between current values in the sensors for this purpose. The required difference in currents in the two resistors enables fluid flow to be computed.Input and output temperature sensors are provided to enable temperature difference to be measured and combined with fluid-flow to indicate the rates of BTU flow. One temperature sensor and the fluid-flow sensors constitute an assembly miniaturized in a solid state chip.
