摘要： An electric power conversion apparatus includes a plurality of semiconductor modules, a frame, a control circuit board, and a reinforcing and fixing member. Each of the semiconductor modules has a plurality of control terminals. The frame receives the semiconductor modules therein. The frame has, at least, a pair of side walls that face each other with the semiconductor modules interposed therebetween. The control circuit board is located outside of the frame and has the control terminals of the semiconductor modules connected thereto. The reinforcing and fixing member extends to connect the side walls of the frame, thereby reinforcing the frame. The reinforcing and fixing member also has the control circuit board fixed thereto so that the reinforcing and fixing member is positioned between the control circuit board and the semiconductor modules.

摘要： A microwave oven includes a gas sensor for detecting the concentration of gas developed from a foodstuff disposed in an oven cavity. When the cooking operation is conducted to a desired level, the gas concentration reaches a preselected level and, hence, an output signal of the gas sensor shows a predetermined output level at which the microwave generation is terminated. An abnormal condition detection circuit is provided for detecting an abnormally high resistance created in the gas sensor due to, for example, disconnection of a warming heater included in the gas sensor. When an abnormal condition is detected by the abnormal condition detection circuit, the microwave generation is terminated and an alarm display is conducted to inform the operator of the abnormal condition.
