  • Motor and motor rotor having embedded permanent magnets
    Patent number: 6225724
    Abstract: A motor embedded with magnets having good properties and productivity. A rotor of this motor includes a rotor core with laminated rotor core plates punched out of an electromagnetic steel plate and studded with bonded magnets of a powdered permanent magnet material and a resin in groups of slits located in the rotor core for each pole of the rotor.

  • Method and apparatus for image generation
    Patent number: 5864374
    Abstract: A dichroic mirror for reflecting red light for optical separating and a dichroic mirror for reflecting red light for optical synthesizing are installed on the same plane in an image generating apparatus of the present invention. In addition, a dichroic mirror for reflecting blue light for optical separating and a dichroic mirror for reflecting blue light for optical synthesizing are installed on the same plane. Accordingly, a compact configuration can be realized. Since a main reflecting mirror is a rotating elliptic mirror and a lamp is located on a focus or around the focus, a lighting equipment which irradiates conic luminous flux can be realized.
