    • A crown forming method of forming a crown on a floating type magnetic head which includes the steps of placing an approximately rectangular-prism-shaped bar, which has magnetic head elements of not less than 1 formed on a side wall thereof in a row, on the convex surface of a jig whose radius of curvature is R1 through an elastic sheet while facing the surface to be processed of the bar to a lapping surface plate having a concave processing surface whose radius of curvature is R2 with the relationship between the radius of curvatures set to R1≧R2, deforming the bar to an arc shape along the longitudinal direction thereof and bonding it on the convex surface together with the elastic sheet, and lapping the surface to be processed by abutting it against the processing surface and moving the surface to be processed relative to the processing surface. A plurality of grooves may be formed on the surface to be processed between the respective magnetic head elements along the short direction of the bar so that the bar is divided into a plurality of divided surfaces, and lapping the respective divided surfaces of the bar is performed by abutting them against the concave processing surface of the lapping surface plate and moving the bar relative to the processing surface.
    • 一种在浮动型磁头上形成表冠的表冠形成方法,包括以下步骤:将形成在其侧壁上的具有不小于1个的磁头元件的大致矩形棱柱形条放置在一排上 通过弹性片将曲率半径R1设置在与棒的待处理面相对的研磨面板上,其曲率半径为R 1,曲率半径R2为曲率半径之间的关系, 设置为R1> = R2,使棒沿其纵向方向变形为弧形,并与弹性片一起将其粘合在凸面上,并且通过将其处理表面抵靠处理表面并移动表面 相对于处理表面进行处理。 可以沿着棒的短方向在各个磁头元件之间的待加工表面上形成多个凹槽,使得该条被分成多个分开的表面,并且对该条的各个分割表面进行研磨 通过将它们抵靠在研磨表面板的凹形加工表面上并相对于处理表面移动该杆。

    • A vacuum extraction system is connected to a reactor vessel in which a chemical vapor deposition (CVD) process is carried out by using a suitable starting gas. The system comprises a pump for extracting a vacuum from the vessel, and a trapping device provided in the vessel and the pump for treating a starting gas pulled from the vessel into the system during the CVD process. The treatment of the starting gas pulled from the vessel is performed by using a gaseous oxidizing agent for separating a deposition component from the starting gas pulled from the vessel as an oxide, whereby a build-up of the component of the gas can be prevented in the pump. The trapping device comprises a tank body for receiving the starting gas pulled therein, and a perforated tube for introducing the gaseous oxidizing agent into the tank body to separate the deposition component of the received starting gas therefrom as an oxide.
    • 真空抽吸系统连接到通过使用合适的起始气体进行化学气相沉积(CVD)工艺的反应器容器。 该系统包括用于从容器中提取真空的泵,以及设置在容器中的捕集装置和泵,用于在CVD过程期间处理从容器拉入系统的起始气体。 通过使用用于从作为氧化物从容器拉出的起始气体中分离沉积成分的气态氧化剂来进行从容器拉出的起始气体的处理,从而可以防止气体成分的积聚 泵。 捕集装置包括用于容纳拉入其中的起始气体的罐体,以及用于将气态氧化剂引入罐体中的多孔管,以将其中所接收的起始气体的沉积成分分离为氧化物。

    • A power transmission belt having a tension section and a compression section, with at least a portion of one of the tension and compression sections being formed from rubber of a first color. A rubber coated canvas covers at least a part of at least one of the tension and compression sections including the portion of the one of the tension and compression sections having the first color. The rubber in the rubber coated canvas has a second color that is different than the first color. A rubber layer having a third color is interposed between the portion of the one of the tension and compression sections and the rubber coated canvas. The third color is substantially the same as the second color.
