Title: Electrolytic capacitor
Inventor: ITO HIDEO
IPC: H01G9/06
Filed: 1988-12-02
Abstract: PURPOSE:To prevent tone quality due to resonance intrinsic for a clamping material from deteriorating by mixing vegetable fiber or animal fiber in an element clamping material to contain a capacitor element in a bottomed cylindrical sheath case to secure it with clamping material made of tar pitch or synthetic resin. CONSTITUTION:In an electrolytic capacitor in which a capacitor element 1 formed by winding an anode foil and a cathode foil through a separator is impregnated with electrolyte, the element 1 is contained in a bottomed cylindrical sheath case 2 and secured with a clamping material 3 made of tar pitch or synthetic resin and the opening of the case 2 is sealed, fiber is mixed in the material 3. In this case, the mixing amount of the fiber is 0.1-50wt.%. If it is 50wt.% or more, clamping force is weakened to be a problem in its practical use, while if it is 0.1wt.% or less, tone quality improving effect cannot be expected. As the fiber, vegetable or animal fiber is employed. Thus, vibration intrinsic for the material 3 is suppressed to improve its tone quality, and an electrolytic capacitor having the material 3 which is not intrinsically vibrated in response to an external vibration is obtained.

Title: Image forming device
Inventor: KIMURA NAOYUKI
IPC: G03G15/08
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of image deterioration in toner image due to paper powder by removing the paper powder incorporated in toner, which remains after a transfer and is recovered to a cleaning member, before the paper powder is carried to a developing device. SOLUTION: As a paper powder removing means, a brush 16, whose top end part abuts on the periphery of a cleaning roller 12, is used. Then, a brush attaching bracket 18 is fixed in a cleaning case 17 and the base end part of the brush 16 is fixedly provided on a supporting plate 19 fixed on the bracket 18. The brush top end part on the free end side of the brush 16 abuts on the periphery of the cleaning roller 12. While the roller 12 is rotated to recover the toner remaining on a photoreceptor 1 after the transfer to the roller 12 is performed, the brush 16 scrapes/removes the paper powder incorporated in the toner.  Since the paper powder is removed before it goes to the developing device 4, the intrusion of the paper powder into the developing device 4 can be prevented and the occurrence of the deterioration in the image quality of the toner image due to the paper powder can be prevented as well.

SOLUTION: An exposure head 23 is formed by preparing a number of blue color LED, connecting an optical fiber to each of them, and disposing a GRIN lens at the distal end of these optical fibers. The exposure head 23 can form images with respect to the image at the distal end face of each optical fiber on the exposure range 24 of photosetting resin as ant optical spot. Although the diameter of the optical spot 55 is 0.5 mm for example, the size of pixels 71 within the exposure region 24 is by far small, e.g. 62.5 μm. Thus, a number of optical fibers on the exposure head 23 are arranged in a matrix displaced in staggered relation in order for each optical spots 55 to be arranged at a pitch of 62.5 μm of the pixel 71 in the major scanning direction (Y axis).  While scanning the exposure range 24 with the exposure head 23 in the ancillary scanning (X axis) direction, a multiple exposure is conducted by making all optical spots 'ON' capable of lightening the pixels relative to individual pixels 71 to be exposed within the exposure region 24.
