Title: Image forming device
Inventor: SUGATA HIDEAKI
IPC: G03G21/00
Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a variation in the rotation of a rotary shaft due to eccentricity and to form a high quality image, by fixing the superimposed identical shapes of fly wheels into positions deviated in a circumferential direction with respect to a rotary shaft. SOLUTION: The photoreceptor drum of an image carrier 1 is rotatably supported on a rotary shaft 2 and the rotary shaft 2 is rotated by a drive means. Fly wheels 3 molded out of a metal plate with a molding die are fixed with fixing means 4 so that the superimposed identical shapes of the fly wheels are deviated in a circumferential direction with respect to the fixing shaft 2. That is, on the assumption that the fly wheels 3 of the identical shapes are eccentric, N fixing holes are formed in advanced in the fly wheels 3 at an interval of 360 deg./N in the circumferential direction, and the eccentric portions of the fly wheels 3 are dispersedly arranged evenly in the circumferential direction, thereby offsetting eccentric elements. Thus, an image forming device which prevents the occurrence of a variation in rotation due to eccentricity and is capable of high-quality image formation is obtained.

IPC: H01L23/50
Filed: 1989-12-05
Abstract: PURPOSE:To prevent crack of a semiconductor element from occurring and improve reliability in an outer lead bending process by providing a reinforcing fixing part at a die pad part where the semiconductor element of a lead frame is adhered. CONSTITUTION:In a case where a mold resin 4 on the surface of a lead frame 1 are removed. a protrusion 8 corresponding to the reinforcing fixing part is provided at the tip part within a mold resin 4 at a die pad part 5. Then, the protrusion 8 has the same thickness as the die pad part 5, is provided with a rectangular shape a having a horizontal width L1 which is longer than the width in horizontal direction of the die pad 5, and is connected to the die pad part 5 through a connection part 9 with a shorter width l than the horizontal width of this rectangular shape a. Thus, in a process for bending an outer lead 7 of the semiconductor device, the die pad 6 is pulled toward the outside and is subjected to stress. However, since a protrusion 8 is provided at the die pad 5, the protrusion 8 can be resistant at the mold resin 4 even if the die pad 5 is subjected to stress so that the stress cannot be centered to the semiconductor element 2, thus reducing the possibility that a crack may be produced at the semiconductor element 2 drastically.
