  • Driving device of rotational body for use in image forming apparatus
    Patent number: 5323211
    Abstract: A driving device for a rotational photoreceptor drum for use in an image forming machine, in which a rotational drive from a motor is supplied through a gear train to the axial shaft of the drum. The shaft is connected to the drum only at the side farthest from the gear train. An inertia member is provided within the drum. A rotational member having a rotational resistance is brought in contact with a non-image region of the drum.

  • Method of making a lead frame by embossing, grinding and etching
    Patent number: 5004521
    Abstract: A process of shaping a thin metal film into a lead frame starts with preparing a thin metal film, an etchant effective against the thin metal film and a photoresist solution resistive to the etchant, followed by coating the entire surface of the thin metal film with the photoresist solution so as to form a multiple level structure having the thin metal film and a photoresist film, and a predetermined pattern is embossed on the multiple level structure so as to break slits in the photoresist film along the periphery of the predetermined pattern, then removing a part of the multiple level structure by using the etchant so that a hollow space is formed therein in the predetermined pattern.
