Abstract: PROBLEM TO BE SOLVED: To provide a universal motor in which a printed circuit board(PCB) is mounted on a rectifier to play a role of an electrical shielding for electromagnetic interference(EMI) generated by an electric arc between the rectifier and a brush. SOLUTION: A universal motor comprises a stator, a rotor, the brush and the printed circuit board(PCB). The rotor includes a shaft, and a rotor core is mounted on the shaft near the rectifier. The rotor core is electrically connected with the rectifier to rotate within the stator. The brush supplies an electrical output to the rectifier and is elastically in contact with the rectifier. A filter circuit reduces electromagnetic radiation from the universal motor and is in contact with the brush. The printed circuit board is mounted on the brush. When electronic arc is generated between the rectifier and brush, the printed circuit board functions as the electrical shielding to absorb a part of radiation generated by electronic arc in order to reduce the electromagnetic interference characteristic of the universal motor.

Abstract: PROBLEM TO BE SOLVED: To provide a projector which has a set of intersected dichroic mirrors and makes the number of elements in the device smaller than the prior art. SOLUTION: This projector includes a light source, a polarized light converter, an intersected dichroic mirror set having the two dichroic mirrors, a modulator and a projection lens. The polarized light converter converts non- polarized white light to polarized white light. The two dichroic mirrors are arranged in intersection and separates the polarized white light to three polarized monochromatic beams. The modulator is placed adjacently to the intersected dichroic mirror set, forms the three polarized and modulated beams by modulating the three polarized monochromatic beams and reflects these beams toward the two dichroic mirrors. The two dichroic mirrors form the polarized and modulated white beams by again combining the three polarized and modulated beams. Finally, the projection projects the polarized and modulated white beams so as to form images.
