Abstract: In a plasma processing system, a method of determining the temperature of a substrate is disclosed. The method includes positioning the substrate on a substrate support structure, wherein the substrate support structure includes a chuck. The method further includes creating a temperature calibration curve for the substrate, the temperature calibration curve being created by measuring at least a first substrate temperature with an electromagnetic measuring device, and measuring a first chuck temperature with a physical measuring device during a first isothermal state. The method also includes employing a measurement from the electromagnetic measurement device and the temperature calibration curve to determine a temperature of the substrate during plasma processing.

Abstract: The present invention relates to providing a temperature sensor that is mountable on an aircraft and includes a thermometer or temperature sensing element for sensing temperature of airflow. A heater is provided on the probe to bias the temperature sensed by the thermometer or temperature sensing element, in a manner such that the temperature measured is at a substantially known offset from the static temperature surrounding the temperature sensor. Control of the offset can be achieved by regulating airflow or heat provided. The heating effect is controlled to be a substantially equal and opposite match to the decreased total temperature resulting from lower airspeed or decreased airflow. In this manner, the thermometer or temperature sensing element will essentially operate at a fixed offset above static temperature, that is the temperature in undisturbed air in which the aircraft is operating, over a fairly wide range of flow rates.

Abstract: A device for measuring the flux received by a specimen in fire test apparatuses has a copper disk or plate of the same dimensions and the same type of surface coating as a typical material specimen, an embedded heating coil and thermocouple, and an insulated sample holder similar to that used for a specimen. The transient response of the embedded thermocouple is measured for several different levels of imposed incident radiation without electrical heating and for several different known levels of electrical heating without any imposed radiation. The principle of Electrical Substitution Radiometry (ESR) is applied, and the transient responses to incident radiation and electrical heating under identical thermal conditions are compared to determine the amount of incident radiation that is actually absorbed by the device while it is being irradiated. The situations are kept thermally identical, thereby insuring that all effects due to heat losses (e.g. convection, radiation and conduction) are exactly the same.

Abstract: A temperature determining device is composed of a temperature detecting unit that detects a temperature of a determination object member based on an intensity of infrared rays from the object member, a unit for determining a temperature for correction that determines a temperature of an opposing member opposed to the object member or a temperature of a member whose temperature changes in correlation to a change in the temperature of the opposing member, and a calculating unit that corrects the detected temperature obtained by the temperature detecting unit using the temperature as the temperature for correction obtained by the unit for determining a temperature for correction. Thus, stable temperature determination can be performed accurately without being influenced by infrared rays from around a determination object member.

The ear temperature measuring unit, the display unit, and the memory unit are controlled by the microprocessor.

The memory unit is partitioned into a plurality of independent memory sectors. Each sector includes a queue data structure, such that the ear temperature measured from each person and the measuring time can be stored in the corresponding memory sector. Therefore, measurement of multiple people can be performed, memorized and retrieved.

Abstract: A device (10) for calibrating tympanic thermometers includes an enclosure (12) which may be heated or cooled depending upon the testing temperature. Within the enclosure (12) there is provided a sealed flask (14) which contains substance (16) which melts at the test temperature (this may be ethylene carbonate, melting point 36.3° C.). Located within the sealed flask (14) is a re-entrant well (18) which provides the blackbody for testing tympanic thermometers and a viewing aperture (20). The well (18) is treated to achieve a high surface emissivity. The device (10) allows the testing of thermometers by measuring the triple point or melting point of the substance (16). As the temperature of the substance (16) is accurately known, so is the temperature in the blackbody cavity (18) and thermometers can be calibrated thereby.

Abstract: A self-detecting type cantilever for an atomic force microscope (AFM) has an electro-flexural conversion element for converting a flexural amount of the cantilever into an electric current or voltage, a temperature measurement element disposed at a front end portion of the cantilever for measuring a temperature, and a heating element disposed at the front end portion of the cantilever for heating the temperature measurement element. The temperature measurement element and the heating element are superposed with each other on a main face of the cantilever via an electrical insulating layer. As a result, even if the amount of electric energy supplied to the heating element is reduced, it is possible to effectively supply an amount of heat necessary for measurement to the temperature measurement element. Therefore, by minimizing the heat to be supplied to a sample and the cantilever, the respondency of measurement is improved and temperature measurement can be performed with a high degree of accuracy.
