    摘要： An integral bearing type electric motor is disclosed, which comprises a bearing body including a spindle, a sleeve surrounding the spindle, an inner or outer ring fitted in or on the spindle, and balls provided between the spindle and sleeve, between the spindle and outer ring or between the inner ring and sleeve. A hub for the rotor of the motor, a flange for the base of the motor or a stator yoke holder is formed by molding together with the sleeve, spindle or inner ring of the bearing body. The number of components is reduced, the number of assembling steps can be reduced, and reduction of the cost of manufacture can be expected.

    摘要： In the manufacture of a casing base for a hard disc drive device, an elongate semi-product of a light metal having a predetermined sectional profile having opposite side frame portions, is extrusion molded and then cut to a predetermined length to obtain an eventual casing base, which is then formed with necessary holes and recessed or raised portions using a press, thus completing the casing base. Like the case of die casting, no cavities are generated, so that it is possible to readily carry out washing and surface treatment. In addition, unlike the case of forming frames in a sole press process, a large number of press forming steps are not involved, and it is possible to permit mass production of a highly accurate and highly rigid product in a small number of steps and at a low cost of manufacture.

    摘要翻译： 在制造用于硬盘驱动装置的壳体基座时，具有具有相对侧框架部分的具有预定截面轮廓的轻金属的细长半成品被挤压成型，然后切割成预定长度，以获得最终的套管基座 ，然后使用冲压机形成必要的孔和凹部或凸起部分，从而完成壳体基部。 与压铸的情况一样，不产生空腔，因此可以容易地进行洗涤和表面处理。 此外，与在底压机中形成框架的情况不同，不涉及大量的压制成形工序，能够以少量的台阶大规模生产高精度，高刚性的产品 制造成本低。

    摘要： A small-sized stepping motor provided with can-type stator yokes and one flat-type stator yoke, all of which are injection molded of a composite powder (i.e., a mixture of a metal powder of a soft magnetic material, a powder of a thermoplastic synthetic resin). The injection molded stator yokes have a considerably large specific electrical resistance, and the stepping motor is free from various disadvantages resulting from a small specific electric resistance.
