摘要： The invention detects the weight of an object by detecting the change in electrostatic capacity due to a change in the distance between electrodes caused by deflection of flat plates, by using a pressure sensitive sensor having flat plates composed of two elastic insulators stuck together across a proper gap and extending parallel to one another, with electrodes provided at the confronting sides of the flat plates, and by transferring the load of the object to be measured to the sensor through a load support. The gap between the electrodes of this pressure sensitive sensor is enclosed, and a hole is provided to allow air to pass into and out of the gap. Furthermore, the surface of the pressure sensitive sensor is coated with a water-repellent substance to eliminate current loss due to dust or dew deposited on the surface of the electrodes. As a result, the weight may be measured accurately without being effected by temperature changes or humidity.

摘要： There is disclosed herein an automatic heating appliance for controlling heating of an object in response to operation of instruction keys and on the basis of the weight of an object to be heated. The appliance includes therein a heating chamber for housing the object, a heater provided on or in the heating chamber for heating the object placed therein, and a turntable provided in the heating chamber for keeping thereon the object during heating. Also included in the appliance are a weight detector for obtaining first weight data in response to the object being placed on the turntable and a temperature compensator for obtaining a second weight data in response to the object being placed thereon, the temperature compensator substantially having the same temperature characteristic as the weight detector. A control unit of the appliance is responsive to the first and second weight data in order to remove an error component due to variation of the characteristic of the weight detector by variation of temperature in accordance with the result of comparison between the first and second weight data so as to determine a weight resulting from only the object. The control unit controls the heating of the object in accordance with variation of the determined object weight.
