摘要： PURPOSE: To realize a surface which is highly soft and easy to work for a roller for record cleaning, by foming the surface with the elastic resin composed mainly of polynorbornane and containing the viscid resin.
CONSTITUTION: The polynobornane is obtained by synthesizing the norbornane with ethylene and cyclopentadiene through the Diels-Alder reaction and then giving the ring oprning polymerization to the norbornane. This polynorbornane is plasticized with addition of the aromatic oil or naphthenic oil to show the elasticity like rubber. Then the viscid resin is added to the elastic polynorbornane in a range of 10W50wt%. Such elastic resin is used on the surface 6 of a rotary roller 2. Thus the dust on a record disc can be cleared away easily.

摘要： PURPOSE:To improve the sweeping of dust by preventing charging with static electricity, by decreasing electric resistance between the roller surface layer of a sweeping tool and a connection part below 10 OMEGA-cm while connecting the roller surface layer to a handle electrically through a supporting member. CONSTITUTION:A dust sweeping tool 1 consists of a roller 2, a supporting member 3 and a handle member 4, the surface layer 6 of the roller 2 is connected electrically to the handle member 4 through both side plates 7 and supporting terminals 8 of the supporting member 3, and electric resistance between the surface layer 6 and the electric connection part set is to OMEGA-cm. Consequently, since the band of a user comes into contact with the handle member 4 during a dust sweep, static electricity on a record disk is earthed through the roller 2, surface layer 6 ad members 3 and 4 to prevent charging, thereby sweeping dust excellently.
摘要翻译：目的：为了通过防止静电充电来改善灰尘的清扫，通过降低扫掠工具的辊表面层和低于10 9欧姆 - 厘米的连接部分之间的电阻，同时将辊表面层电连接到手柄通过支撑构件。构成：除尘工具1由辊2，支撑构件3和手柄构件4组成，辊2的表面层6通过两侧板7和支撑端子8与手柄构件4电连接支撑构件3，并且表面层6和电连接部件组之间的电阻为<= 10 9欧姆 - 厘米。因此，由于在灰尘扫描期间用户的带子与手柄构件4接触，所以在记录盘上的静电通过辊子2，表面层6的构件3和4接地，以防止充电，从而很好地清除灰尘。
