摘要： A radiation thermometer measures temperature of the eardrum. The thermometer comprises a signal processor for calculating a temperature from an output of a light receptor, which receives only the infrared rays radiated directly from the eardrum and/or vicinity of it, and a notification system for notifying the temperature resulted from the calculation. Since the structure does not receive an influence of any radiant heats from other than those of the eardrum and/or vicinity of it, temperature change of a probe does not become a factor of measuring errors, so as to offer an accurate measurement of temperatures. An infrared-receiving element is positioned within a triangle configured by an intersection between a light path and an optical axis, and two image points of hypothetical end points formed by an optical condenser, when viewed in a cross sectional plane including the optical axis of the optical condenser, where (a) the light path is a path that extends from the hypothetical end point to the image point of the hypothetical end point formed by the optical condenser by passing through a rim of the optical condenser on the same side as the hypothetical end point with respect to the optical axis, and (b) the hypothetical end point is a point at which a straight line drawn from the rim of the optical condenser toward the probe in a manner to be tangent to an inner surface of the probe on the same side as the rim of the optical condenser with respect to the optical axis crosses a plane at a tip of the probe.

摘要： A high frequency heating arrangement includes a power converting unit with one or more semiconductor devices which dissipates a slight heat loss. A magnetron receives an output from the power converting unit and supplies electromagnetic waves to a heating chamber. The magnetron dissipates a heat loss that is relatively larger than that of the power converting unit. A cooling fan has a motor which dissipates a heat loss which is relatively smaller than that of the power converting unit. The cooling fan is for cooling the power converting unit and the magnetron. A case is provided in which at least the power converting unit and the magnetron are housed and which is made of an electricity-conductive material. A cooling air passage, along which the motor and the case are arranged, and through which air flows from said cooling fan is provided. Air sent from the cooling fan first cools the motor, then cools at least a portion of the power converting unit, and finally cools the magnetron.
