Title: V-belt
Inventor: YAMADA KAZUHIRO
IPC: F16G5/18
Filed: 1989-10-23
Abstract: PURPOSE:To improve durability as well as to prevent noise and abrasion from occurring by specifying the dimensions of combination between a chain constituting a V-belt being stretched across a pulley where both fixed and movable conical members are set up in reverse and a friction block with a chain inserting part. CONSTITUTION:The offset of a center position of V-shaped grooves in both driving and driven pulleys turns to a peak at the specified transmission gear ratio. At this time, a difference between both elements is set up in link plates 301, 302 is mesh with these pulleys and a friction block 33 so as to make a relationship between width W1 of unwrenched link plate recess parts 305, 306 and friction block thickness W2 securable. In brief, it means deltamax; maximum slippage in a groove center position of the pulley, S; pulley center distance, W; friction block width, pi-2psi; winding angle of the belt to the driving pulley at time of maximum offset occurrence, pi+2psi; whereby it is set down to an equation of W1-W2=deltamax.W/Scospsi when value is setting to a winding angle of the belt for the pulley. With this constitution, improvement in durability of the belt and pulley and prevention against noise and abrasion is well promoted.

Title: Manufacture of electrophotographic photoreceptor
Inventor: SAKAMOTO MASAYUKI
IPC: G03G5/10
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To manufacture a low-cost electrophotographic photoreceptor preventing the occurrence of an interference fringe pattern appearing at the time of image formation without giving an ill effect to the electrophotographic characteristic. SOLUTION: A carrier 19 of an electrophotographic photoreceptor completed with washing is dipped in a solvent 81. The solvent 81 dissolves the resin forming the carrier 19, and the outer periphery of the carrier 19 is roughened. After the carrier 19 roughened on the outer periphery is dried, a photosensitive layer is formed on the outer periphery. The light reaching the surface of the carrier 19 is scattered, and the interference with the light reflected on the surface of the photosensitive layer is reduced. The occurrence of an interference fringe pattern appearing at the image formation can be prevented.

Title: Polyphase synchronizing clock generation circuit
Inventor: AOKI HIROKAZU
IPC: H03K5/15
Filed: 1987-11-02
Abstract: PURPOSE:To accelerate control between devices by using a delay circuit which inputs a clock with the same frequency and a clock with the double frequency as that of a control clock and a clock generatins device consisting of a flip-flop in each device. CONSTITUTION:The title circuit is constituted of the delay circuit (duty correction circuit) 120 which delays either the leading edge or the trailing edge of an input clock to generate a clock of duty (a ratio of 'high' level period for one cycle) 50% for the generation of a polyphase control clock of duty 50%, and edge trigger flip-flops 130 and 131 which generate the polyphase control clock of duty 50%. Therefore, since the phase of the polyphase control clock generated at each controller is the same one because the same relation exists in the input clock f2 of the delay circuit and the data terminal input clock f1 of the edge trigger flip-flops 130 and 131 in each controller, the synchronization of the polyphase control clock between the controllers can be taken. In such a way, the control between devices can be accelerated.
