摘要： PURPOSE:This apparatus is composed of a rotating main body, an armature and magnetic coils. By coating a film layer of soft metal on one side of the frictional surfaces of the rotating main body and the armatures, to improve the torque transmission force and to decrease the frictional noise. CONSTITUTION:This apparatus is composed of a rotational main body 3, magnetic coils 7 and a circular plate type armature 12 of magentic material. The frictional surface 3a of the rotational main body 3 is formed by coating a film layer 3a of soft metal, such as lead-tin alloy, which is smaller in hardness and greater in frictional coefficients than the magnetic material composing the armature 12. By doing so the frictional force between the frictional surfaces 3a, 12a is increased and these surfaces 3a, 12a are guarded. Therefore it is possible to protect local disposition in the early stage of use, smooth the roughening of the surfaces 3a, 12a, improve the torque transmission force, decrease the contact noise.
摘要翻译：目的：本设备由旋转主体，电枢和电磁线圈构成。通过在旋转主体和电枢的摩擦面的一侧涂覆软质金属膜层，以提高转矩传递力并降低摩擦噪音。构成：该装置由旋转主体3，磁性线圈7和磁性材料的圆板型电枢12构成。旋转主体3的摩擦面3a通过涂覆硬度较小的软质金属（例如铅锡合金）的薄膜层3a，摩擦系数比构成电枢12的磁性材料大。通过进行因此摩擦面3a，12a之间的摩擦力增加，这些表面3a，12a被保护。因此，可以在使用的早期保护局部布置，平滑表面3a，12a的粗糙化，提高扭矩传递力，降低接触噪声。

摘要： PURPOSE: To give the wear resistance by mixing the linear type polyphenylene sulfide resin, he carbon fiber and the poly tetra fluoro ethylene at the prescribed ratio to form a tip seal. CONSTITUTION: Tip seals 21, 31 provided on the tip of spiral blades 22,32 of fixed and movable scroll members 2, 3 of a scroll compressor are formed by appropriately using the composition consisting of 20-90% linear type polyphenylene sulfide resin (linear type PPS), 5-40% carbon fiber (CF) and 5-40% poly tetra fluoro ethylene (PTFE). The linear type PPS includes poly phenylene sulfide resin having the straight chain molecular structure and the pitch type graphite CF which is obtained through the heat treatment of the carbon fiber manufactured of petroleum or coal pitch at high temperature around 2100 deg.C is preferably used.
