    摘要: Device and method for fixing an image in which a vibrator, which generates ultrasonic waves by applying a voltage, and a horn connected thereto are arranged opposite a pressure roller with an endless belt passing between the horn and the pressure roller. Recording paper is carried between the belt and the pressure roller so that an image surface thereof is brought into contact with a rubber layer on the endless belt. Ultrasonic vibration is transmitted to the image surface of the traveling recording paper via the belt, thereby directly heating and melting toner so that the image is fixed on the recording paper.

    摘要: A reflector 10 is formed so as to have a long side along a scanning direction of a ray bundle. The reflector 10 includes a thin-plate-shaped reflector body having one plane to be a reflection plane 20 and upper and lower ribs 21a and 21b each extending from the reflector body in a back side. The reflector plane 20 is formed of a curved plane having positive power at least in the scanning direction, i.e., a so called free-form plane. The reflector 10 is supported by protrusions 31, 32 and 33 at three points, i.e., first, second and third support points S1, S2 and S3 located in the vicinities of one end portion of the reflector, the other end of thereof, and a center portion thereof, respectively. A distance L1 between an imaginary straight line V1 joining the first and second support points S1 and S2 and the third support point S3 is larger than a sag L2 of the reflector 20. The center of gravity G of the reflector is located inside of an imaginary triangle V3 joining the first, second and third support points S1, S2 and S3.

    摘要: A canceling exciting coil is supported by a coil supporting member of electrically insulating material fitted to an arch core. A canceling current Ic of opposite phase to a main current I flowing in the magnetic field generation circuit of the exciting coil by means of an exciting circuit is made to flow in a canceling magnetic field generation circuit provided with a canceling exciting coil, and generates canceling flux Mc. The idle component of the AC voltage generated in the canceling exciting coil is minimized by changing the number of turns n, coil inner area, and winding distribution of the canceling exciting coil, and adjusting canceling current Ic.
