Patent JP-2000249202-A (JP)
Title: Driving apparatus
Inventor: SAKANASHI SHINYA
IPC: G03G15/00
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for driving a photosensitive member or the like, which is capable of reducing vibration in a belt advancing direction by a small-sized inertia body, saving space of the whole apparatus, preventing an image quality from deteriorating due to the vibration, and reducing vibration in a direction perpendicular to the belt advancing direction and reducing noises. SOLUTION: A rotation-driving force is transmitted to a photosensitive member 1 (rotational body) through a belt 6. A tension roller 8 exerting tension to the belt 6 is provided with a fly wheel 9 (inertia body). This reduces the belt advancing direction resonance frequency resulting from the vibration occurring when the belt 6 and the pulleys 6, 7 mesh with each other. The diameter of the tension roller 8 is made smaller than that of the photosensitive element driving pulley 7 or the like, thereby enabling the fly wheel 9 to rotate in a high speed, which provides a large inertia effect.

Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To execute operations of an electromagnetic shield and electrostatic shield by providing a shield member using a metal material at an SMD driver module for an EL. SOLUTION: A shield cover 3 formed of a thin metal plate is mounted at a driver module. A magnetic material is preferable as material of the cover 3, and material having high shielding effect such as iron or nickel is used. A material cladded with copper foils on both surfaces without providing a shield cover of a separate component is sued for a circuit board. In the case of forming a pattern by etching, the foil is retained to cover overall surface of a lower surface of the board, used as a shield pattern 4, an hence a sufficient shielding effect is obtained. Since there is adverse influence if a shield member is not effectively grounded, a ground terminal 5 is formed at part of the cover 3 to have spring property.  In the case of mounting at the board 1, it is brought into pressure contact with a through hole electrode used also as a ground wire of the electrodes at four corners and grounded.

Filed: 1978-04-28
Abstract: PURPOSE: To offer proper air-fuel-ratio by keeping the specific opening ratio of a solenoid valve which opens or closes a fuel supply passage on the basis of an output level of a circuit detecting and memorizing an air-fuel-ratio of mixture.  
     CONSTITUTION: The output of a comparator 12 is sent to a detector 15 in a detective memory 20. When an output average voltage of the comparator 12 is different from a specified reference value, its signal is stored in a memory circuit 16. A level convertor 17 of a delta wave oscillator 11 converts a center level of a delta wave by the output of the memory circuit 16. And if a center level of the output from a comparison integrated circuit 10 goes out, the memory 16 works the level convertor 17 for coincidence. An air-fuel-ratio calculation circuit, putting out shifted center level, keeps constant control range to work the solenoid for proper air-fuel-ratio.
