    • A hard disk drive device is provided, which is designed small, thin, and at low-cost. The hard disk drive device includes a case with an upright shaft, and a cylindrical hub coupled to the shaft. One end of the hub is closed by a thrust plate so that the hub has a bottomed cylindrical shape, and a hard disk is fixedly mounted on an outer peripheral part of the hub. An oil is filled in a clearance between an inner surface of the hub and an outer surface of the shaft, whereby a hydrodynamic radial bearing is formed between the inner periphery of the hub and the outer periphery of the shaft, and a hydrodynamic thrust bearing is formed between the top face of the shaft and the thrust plate. Between an outer peripheral part at the base end of the shaft and an inner peripheral part at the open end of the hub is formed a seal part in which a larger clearance is formed between the shaft and the hub than a clearance in the hydrodynamic radial bearing and in which the oil surface is positioned. An oil surface adjusting hole and a plug for sealing the hole are provided in the case opposite the seal part. A motor for rotating the hub is disposed between the outer peripheral part at the open end of the hub and the case.
    • 提供了一种硬盘驱动器件,其设计小巧,薄型,低成本。 硬盘驱动装置包括具有直立轴的壳体和联接到轴的圆柱形毂。 轮毂的一端由止推板封闭,使得轮毂具有有底圆筒形状,并且硬盘固定地安装在轮毂的外周部分上。 油被填充在毂的内表面和轴的外表面之间的间隙中,由此在轮毂的内周和轴的外周之间形成流体动力学径向轴承,并且流体动力推力轴承是 形成在轴的顶面和止推板之间。 在轴的基端部的外周部和轮毂的开口端的内周部之间形成有密封部,在该密封部中,在轴和轮毂之间形成比在流体动力学径向轴承中的间隙更大的间隙 并且其中油表面被定位。 在与密封部相对的壳体中设置油面调整孔和密封孔的塞子。 用于旋转毂的电动机设置在轮毂的开口端的外周部与壳体之间。

    • A blade rubber having both of superior durability and wiping performance can be manufactured by using a non-diene-based rubber without environmental burden. A pair of blade-rubber molded bodies molded from the non-diene-based rubber is subjected to an irradiation treatment to generate radical active sites, and monomers are bound by graft polymerization as beginning at the radical active sites. Also, the monomers are adhered on a surface of the blade rubber either before or after the generation of the radical active sites. The irradiation treatment and the graft polymerization may be simultaneously performed or independently performed in this order. In this manner, a surface treatment for reducing friction of the non-diene-based rubber having superior durability can be performed without halogen, and therefore, a blade rubber having superior durability and wiping performance can be manufactured.
    • 具有优异的耐久性和擦拭性能的刀片橡胶可以通过使用不带环境负荷的非二烯类橡胶来制造。 对由非二烯类橡胶成型的一对刀片橡胶成型体进行照射处理,生成自由基活性部位,单体在自由基活性部位开始接枝聚合。 此外,单体在产生基团活性部位之前或之后粘附在刮片橡胶的表面上。 照射处理和接枝聚合可以按顺序同时进行或独立地进行。 以这种方式,可以在没有卤素的情况下进行用于降低耐久性优异的非二烯系橡胶的摩擦的表面处理,因此,可以制造具有优异的耐久性和擦拭性能的刮板橡胶。
