Thermometer, electronic device having a thermometer, and method for measuring body temperature

A deep-area temperature calculating device 441 calculates the temperature Tcore of a deep area on the basis of a first body-surface temperature and second body-surface temperature from body-surface sensors 31A and 31B, and on the basis of a first intermediate temperature and second intermediate temperature from intermediate sensors 32A and 32B. Since the temperature Tcore of the deep area is determined from two body-surface temperatures and two intermediate temperatures, the temperature Tcore of the deep area can be calculated regardless of the heat resistance of the thermometer without making any assumptions regarding the heat resistance of the area that extends from the deep area of the human body to the body surface. Thereby, the temperature Tcore of the deep area can be calculated and the body temperature can be measured with high precision regardless of differences in the body type or contact with clothing or bedding.

Heat treatment apparatus for heating substrate by irradiation with flashes of light, and heat treatment method

A first flash heating is performed in which a lower flash lamp irradiates a back surface of a semiconductor wafer with flashes of light, so that heat conduction from the back surface to a surface of the semiconductor wafer raises the temperature of the surface from the room temperature to an intermediate temperature. Then, a second flash heating is performed in which an upper flash lamp irradiates the surface of the semiconductor wafer with flashes of light, to raise the temperature of the surface of the semiconductor wafer from the intermediate temperature to a target temperature. Since only the irradiation with flashes of light emitted from the lower flash lamp and the upper flash lamp is used to cause the semiconductor wafer having the room temperature to reach the target temperature, all heat treatments can be completed in an extremely short time of one second or less.
