Abstract: An electric fan comprises a rotary shaft supported on a mounting base plate. The rotary shaft is extended through a cylindrical stator and on a tip of the rotary shaft, the bottom of a cup-shaped rotor yoke as well as an impeller are secured. The stator is enclosed in the rotor yoke, on whose inner wall an anisotropic rotor magnet magnetized in the reverse polarity alternately in its circumferential direction is secured. The stator and the rotor form a DC brushless motor, whereby the impeller is rotated through the rotation of the rotor and the rotary shaft. In the proximity of the rotor magnet, there is provided a hall integrated circuit (IC), through which a rotating position of the rotor may be detected. On the basis of the rotating position signal from the hall IC, a microcomputer controls the current flowing period in such a manner that the current flowing through the stator coil will partly overlap between each phase.

Abstract: An image forming apparatus utilizes a paper which has a part capable of recording a visible image on the surface thereof and a part capable of recording magnetic information thereon. A toner image is formed on the visible image recording part of the paper by a photosensitive drum, a developing apparatus and a transferring device. A magnetic information signal is recorded on the magnetic recording part of the paper by a magnetic record head. A discharging device is provided for discharging the paper on which both a visible image and magnetic information are recorded.

Abstract: A printer head comprises a plurality of light emitting portions (104) on one side of a rectangular substrate (101), the portions (104) being aligned in parallel with a longitudinal direction of the substrate, and two driver circuit units (112, 113) on the other side of the substrate (101) such that the respective input/output terminals of the units (112, 113) are aligned in a direction orthogonal to the aligning direction of the light emitting portions (104). Each of lead electrodes (106) of the light emitting portions (104) is connected to one of output terminals of first and second driver circuit units (112, 113) from one of first conductive strip lines (108) through a resistor (111), and the input terminals of the first and second driver circuits (112, 113) are connected to external connecting terminals (118).

Abstract: An electrophotographic copying machine includes a photosensitive drum. A first electrostatic latent image according to an original copy image is formed in a state wherein a certain electric charge is accumulated and an original copy image formed by a first light source like a halogen lamp is focussed on this photosensitive drum. In order to form an additional information other than the original copy image, an LED array as a second light source is provided. By the second light source the additional information is formed on the photosensitive drum as the second electrostatic latent image. In case of recording the additional information, a shield member is utilized to prevent the electrostatic latent image by the original copy from being formed in the corresponding region of the photosensitive drum. The photosensitive drum comprises a material like amorphous silicon which is able to react to both first and second light sources.

Abstract: A microstripline for use in a microwave heating comprising conductors each provided over both surfaces of a dielectric base plate. A plurality of slits are arranged distributed in the propagating direction of a microwave on at least one conductor, thereby to form a ladder portion. At least one conductor having the ladder pattern is sandwiched by a silicone resin.

Abstract: An electrophotographic copying machine includes a photosensitive drum on which an electrostatic latent image is formed, a developing apparatus for developing the electrostatic latent image into a toner image, a transferring apparatus for transferring the toner image to a copy paper supplied from a paper supplying portion, a fixing apparatus for heating the copy paper having the toner image transferred thereto to fix the toner image, and a paper ejecting roller for ejecting the copy paper having the toner image fixed thereto to the exterior of the machine body. The copying machine elements are arranged so that the copy paper transporting path from the paper supplying portion to the paper ejecting portion is divided into two assembly units, the assembly units which can be removed from respective predetermined attached positions toward the exterior of the copying machine body in a direction opposite from each other and parallel to the transporting direction of the copy paper.
