摘要： A rotor is formed by a rotary frame 3 composed of a nonmagnetic material, a field magnet 5, a yoke 4 and an auxiliary yoke 7. A disk 12 is mounted on the rotary frame 3. An opening 4b is formed in the yoke 4 to thereby cause attractive magnetic flux from the field magnet 5 to effectively act on a clamping yoke 13 of the disk, so that the disk 12 can be firmly clamped. The yoke 4 covers the circumferential part of the field magnet 5 on its disk 12 side to thereby cut off magnetic flux leakage toward the disk 12, so that its adverse effect on the recording surface of the disk 12 can be avoided. The auxiliary yoke 7 so arranged that a stator coil 6 is interposed between the auxiliary yoke 7 and the field magnet 5 is secured to the rotary frame 3 to thereby increase effective rotating magnetic flux so that output torque is increased.

摘要： The invention provides a soldering flux for mounting circuit substrates, which is free from any organic solvent attributable to air pollution and dispenses with any washing step. The soldering flux is obtained by dissolving a rosin modified by an unsaturated organic acid according to the Diels-Alder reaction in an aqueous solvent. A volatile basic agent may further be contained in the flux.
摘要翻译：本发明提供了一种用于安装电路基板的助焊剂，其不受任何有机溶剂的影响，可由于空气污染而排除任何洗涤步骤。焊剂通过将根据Diels-Alder反应的不饱和有机酸改性的松香溶解在水性溶剂中而获得。挥发性碱性剂可以进一步包含在助熔剂中。
