Abstract: 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.

Abstract: An oven with a humidity conditioner is capable of cooking food by appropriately humidifying or dehumidifying it while the amount of steam contained in an oven cavity is being regulated. The oven includes a heater or magnetron for heating the food accommodated in the oven cavity, a humidity regulator for regulating the humidity inside the oven cavity, a cooking method selector for selecting a cooking method, and a controller for controlling the humidity regulator in response to a signal from the cooking method selector to selectively humidify and dehumidify the interior of the oven cavity.
