Title: Image forming device
Inventor: KAWANO YUZO
IPC: G03G15/08
Filed: 1991-06-21
Abstract: PURPOSE:To prevent deterioration in an image caused by the missing of the image on both end parts of the image by providing an elastic member on the back side of a photosensitive body so as to press a developing roller via the photosensitive body. CONSTITUTION:An elastic member 28 made of foamed ulethane resin, etc., is stuck to a supporting member 29 attached to the inside of the photosensitive body 1 by an adhesive member such as a double coated tape, and provided so as to press-contact to the back part of the photosensitive body 1 coming unto contact with a developing roller 12. The noncontact space D of the photosensitive body 1 and the developing roller 12, occurring by the thickness of a developing roller side seal 15, is reduced with the pressing force of the elastic member 28 press-contacting to the back part of the photosensitive body 1 coming into contact with the developing roller 12. Therefore, noncontact regions B and C are reduced, and an image region A is increased. Thus, the deterioration in the image caused by the missing of the image on both end parts of the image is prevented, the elongation of the developing roller 12 and the photosensitive body 1 in a main scanning direction, for securing the image region, is not required, and the enlarging of the machine is avoided.

Title: Solenoid
Inventor: HAYASHI KENJI
IPC: H01F7/16
Filed: 1981-09-21
Abstract: PURPOSE:To permit operating voltage to be set within a narrow range by a solenoid  wherein a coil spring is stretched between the cut-and-raised-up portion of a leaf spring  constituting a movable portion and the leaf spring attached portion of a mounting  metal plate. CONSTITUTION:As increasing DC current is applied to a hollow coil 3, the magnetic  field is generated. And a magnetic force is enlarged with for each increase of the applied voltage. A magnet 7 has its magnetic poles reversely disposed in the direction  with respect to those of the coil 3. Thus, if DC resistance and the winding number of the hollow coil 3, the magnetic force of the magnet 7, the spring coefficient of a leaf  spring 4 as well as the load of a coil spring 9 are set properly, a movable portion A  descends by a distance corresponding to the applied voltage with 4b being as a fulcrum  due to the resilient force between the hollow coil 3 and the magnet 7. On this occasion, the applied voltage can be set within a narrow range by adjusting angles of cut- and-raised-up portions 1c and 4c. Namely, in case the applied voltage causing the movable portion A to move a given distance is small, cut-and-raised-up angles theta1 and theta2 are  set large thereby to increase the spring force of the coil spring 9, while in case of the  applied voltage is large, the angles theta1 and theta2 are set small thereby to decrease the  spring force.

CONSTITUTION:A p<+> type channel forming region 2 and an n<+> type source region 3 are laminated and formed on an n<-> type drain region 1a, the entire surface is covered with a mask 10, an aperture is bored, and then the V-shaped groove 9 which goes into the region 1a is formed by anisotropic etching. Next, a part of the mask 10 is removed, resulting in the exposure of the shoulders 8 of the groove 9, thereafter, an oxide film 11 is generated on the surface of the groove 9 and that of the region 3 by oxidation, and the sharp angles existent at the shoulders 8 and the bottom 7 of the groove 9 are changed into angles with rounding which has the radius of curvature of 10% or more of the thickness of the gate oxide film. Afterwards, the oxide film at stepwise difference part is thickened more than the gate oxide film 4 provided later by partially leaving the film 11 in the neighborhood of an aperture end 12, and the unnecessary film 11 is removed from the surface of the groove 9. Then, windows are opened by adhering the film 4 as normal, and gate and source electrodes 5 and 6 are mounted.
