摘要： Disclosed is a damping member comprising, as main components, a petroleum resin, asphalt and mica. By selecting and using mica as the filler and incorporating mica in an amount smaller than the amount of asphalt, the adhesion follow-up property to a substrate can be improved.This damping material can be attached simply and assuredly to a substrate having a curved surface, such as a tube or pipe, an air-conditioning duct or a part of a building or vehicle by heat-pressing or heat-fusion-bonding, and a product having an excellent damping effect is provided.

摘要： A thermal adhesive vibration damping sheet comprising a sheet substrate having crystalline polyolefin particles attached to a surface thereof, said polyolefin particles having a mean particle size of 1 to 20 .mu.m and exhibiting an endothermic curve having a high temperature side endothermic peak in the range of from 50.degree. to 230.degree. C. as measured by a differential scanning calorimeter. The sheet has improved blocking resistance, adhesion to sheet steel through heat fusion, and impact resistance at low temperatures.

摘要： A charging and/or discharging unit for an image formation device may include a discharge wire extending in a lateral direction (a second direction) perpendicular to a first direction, the first direction corresponding to a moving direction of the surface of a photosensitive drum and parallel to the surface of the photosensitive drum. The discharge wire may be distanced from the surface of the photosensitive drum. Shield electrodes and a grid electrode are opposed to the discharge wire, with a distance therefrom and extending along the lateral direction. The shield electrodes and the grid electrode may include ribs extending in the lateral direction, respectively. In one or more examples, the ribs may correspond to recessed portions in a surface of the corresponding electrodes and may be located out of a specified circular area.
