    • There is provided a method of manufacturing magnetic head sliders comprising the steps of cutting a material block, which may be of sintered ferrite or ceramic material, to form a core block and slider block. A groove is formed in the core block, which is bonded to the slider block using techniques to provide a magnetic gap. Thereafter the core block is machined to form a plurality of head cores, followed by machining the slider block to form in parallel a number of sliders, which are lapped and then sliced into individual magnetic head sliders. To prevent particles of material from the magnetic head sliders from separating from the sliders and causing deleterious effects, such as head crashes, a heat treating process is employed in which the slider block and core block are treated for from 3 to 20 hours at a temperature of from 100.degree. C. to 150.degree. C., at an ambient air pressure of from 1.5 to 5 kg/cm.sup.2 and at a relative humidity of not less than 60%. In one embodiment the heat treatment is performed immediately following the step of cutting the material to form the core block and slider block. In another embodiment, the heat treatment is performed immediately prior to lapping the sliders.
    • 提供了一种制造磁头滑块的方法,包括以下步骤:切割可以是铁氧体或陶瓷材料的材料块,以形成芯块和滑块。 在芯块中形成凹槽,该凹槽使用提供磁隙的技术结合到滑动块。 此后,加工芯块以形成多个头芯,随后加工滑块以平行地形成多个滑块,这些滑块被研磨,然后切成单独的磁头滑块。 为了防止磁头滑块中的材料颗粒与滑块分离并引起诸如头部碰撞的有害影响,采用热处理工艺,其中滑块和芯块在温度下处理3至20小时 的温度为100℃至150℃,环境空气压力为1.5至5kg / cm2,相对湿度不小于60%。 在一个实施例中,在切割材料的步骤之后立即进行热处理以形成芯块和滑块。 在另一个实施例中,在研磨滑块之前立即进行热处理。

    • A stator of a motor includes a stator core having a plurality of teeth forming slots between any two adjacent teeth and a plurality of phase coils provided in the slots, each formed by wave winding and made of a continuous wire. Each phase coil includes a first wave winding bundle and a second wave winding bundle that is passed through a first slot and a second slot. The first slot is located adjacent to one side of a group of slots through which the phase coils other than said each phase coil are passed and the second slot is located adjacent to the other side of the group of slots. The first wave winding bundle is passed through a third slot and a fourth slot. The third slot is located adjacent to the first slot on the opposite side of the first slot from the group of slots and the fourth slot is located adjacent to the second slot on the opposite side of the second slot from the group of slots.

    • A work W is rotated on a lower grinding wheel 13 provided on a work support base 11. Both surfaces of the work W are simultaneously subjected to grinding process by an upper grinding wheel 24 provided on a grinding shaft 22 of a grinding head 21 and the lower grinding wheel 13. The work W is applied with a pressure force of a primary load through the grinding shaft 22 by a piston rod 36 of a primary pneumatic cylinder 35 which is operated by a first air pressure. The work W is also applied with a pressure force of a secondary load through a lever member 43 by a piston rod 46 of the secondary pneumatic cylinder 45 which is operated by a second air pressure higher than the first air pressure. By adjusting the second air pressure, the pressure force is controlled.
