摘要： A vehicle body side structure is provided to prevent deformation of a structural member due to deformation of a door during a side collision. The vehicle body structure reduces the possibility that the structural member contacts an occupant and obtains an excellent impact absorption effect when the door contacts the occupant. The vehicle body structure has a body side portion with the structural member, and a door coupled to the body side portion to open and close relative to the structural member. An energy absorption member is coupled to the door. A door engagement mechanism is coupled between the door and the side structural member. The door engagement mechanism is arranged to hold the door and the structural member together. A collision sensor generates a collision signal when a side collision is detected by the collision sensor. A door release mechanism is connected to the door engagement mechanism to release the door from the structural member in response to the collision signal. The energy absorption member can be a block of compressible material located in the door, or an air bag, or a frame member with a fragile portion.

摘要： The invention relates to a microwave oven which neither generates hot spots nor destroys a magnetron by shutting microwaves when there is no load to be heated. This microwave oven is constructed so that the impedances are matched when there is a load, and the impedances are unmatched when there is no load, by shifting the location of the opening of the cooking chamber from the center of the wave guide. When there is no load, as most of the microwaves are converted to standing waves and the pressing waves do not reach the cooking chamber, then it becomes possible to prevent dangers such as the abnormal irradiation of any part, the destruction of the chamber case owing to the occurrence of the heat spot, and the abnormal heat generation due to the leakage of the short waves.
