摘要： A microwave oven door includes a shielding panel, which is made of a material through which microwaves cannot pass, having a contact section that opposes a front panel of the oven when the door is closed. A plurality of slits arranged in the contact section and/or the front panel, or both, prevent microwaves from leaking out through a gap formed between the front panel and the contact section. The slits are arranged in at least one row shaped as a closed loop and are evenly spaced from each other. The length of each slit corresponds to about 1/2 of a wavelength of a microwave, and the width of each slit corresponds to no more than 1/16 of the wavelength of the microwave. The interval between two adjacent slits corresponds to no more than 1/16 of the wavelength of the cooking microwave.

摘要： An AC/DC type microwave oven has a function of managing an input power source. The AC/DC type microwave oven comprises a rotatable inverter which inverts a DC power source to an AC power source by a rotational force, a high voltage transformer which receives a common power source or an AC power inverted by the rotatable inverter and outputs a higher voltage, a magnetron which is driven by the high voltage outputted from the high voltage transformer and radiates a microwave and a power control unit for sensing a signal from a power selecting key and preventing the AC and DC power sources from being simultaneously inputted. Therefore, both of AC power and DC power are prevented from being simultaneously supplied to the microwave oven which could result in a malfunction, or an overload occurs in the electric components of the microwave oven. Therefore, only one input power of the common and DC power sources is selected and, the microwave oven is operated properly. The remaining voltage of the battery is always detected and displayed through the display, thereby preventing a complete discharge of the battery.

The terminal members are isolated electrically from each other by means of remote-locating, respectively. A conducting member is installed in the door, and both ends thereof are revealed on the one side of the door. The pair of terminal members contact with ends of the conducting member when the door is closed. Then, the supply of current supplied from electrical power to the high voltage transformer is controlled. Accordingly, the structure of the microwave oven is simplified. The AC/DC type microwave oven is capable of being prevented from encountering faulty switching operations according to large amounts of direct current when the DC input power source is used.

摘要： A method for making a commutator comprising steps of arranging at least one pair of commutator members to be spaced apart from each other, and molding a product by injecting an insulating resin; shaping the product to the product having a real circular sectional cross section; heating the product to a predetermined temperature; cutting protruding resin portions between the commutator members, to the align outer circumference of the commutator body with the outer surfaces of the commutator members. The predetermined temperature is that which rises when the commutator is rotated, and accordingly the predetermined temperature ranges from sixty to eighty degrees Centigrade (60° C.-80° C.). The finished commutator has grooves on the commutator body between the commutator members. The grooves undergo thermal expansion when the commutator is rotated and the temperature rises to a predetermined degree, so that the commutator has a real circular sectional cross section. Accordingly, the contact between the commutator and the input and output brushes is properly performed, and no noise occurs.
