    • A method for preparing a biaxially stretched polyether ether ketone (PEEK) film having excellent precision in thickness, insulating properties and heat shrinkage from an amorphous PEEK film which includes a first stretching step of roll-stretching the amorphous PEEK film in a temperature range of from 50.degree. C. to (Tg-10).degree. C. in a stretching ratio of from 150% to 350% in the progress direction of the film while a necking phenomenon is caused in the film; a second stretching step of stretching the film in the temperature range of from Tg to 170.degree. C. in a direction at right angles to the stretching direction in the first stretching step in a stretching ratio of from 150% to 350%; and a heat set step of thermally setting the stretched film at two stages in the temperature range of 210.degree.-330.degree. C. and the temperature range of 180.degree.-210.degree. C.

    • A buffering device used in a hinge structure of a lid or cover, such as stool lid of a toilet stool of Western style, which is pivoted on a horizontal axis and generally opened upwards by hand and closed downwards by gravity, comprising two members such as of coaxial cylinder type having mutually facing surfaces, respectively, and being combined coaxially to enable relative rotation, and at least one idle member disposed within a gap between the facing surfaces to roll with the relative rotation, and including no buffering fluid, in which the torque for closure is made large as compared with the torque for opening, so that the lid can be opened lightly when it is opened by hand, while it is automatically braked for preventing it from colliding against the stool body to produce an undesirable strike sound when it is naturally closed by gravity.
    • 一种用于盖或盖的铰链结构的缓冲装置,例如西式马桶便盆的便盆盖,其在水平轴线上枢转并且通常由手重新向上打开并且由重力向下关闭,包括两个构件,例如 分别具有相互面对的表面并且同轴地组合以实现相对旋转的至少一个同轴圆筒型,以及设置在相对表面之间的间隙内的至少一个空闲构件,以相对旋转滚动,并且不包括缓冲流体,其中 与打开的扭矩相比,关闭扭矩变大,从而当用手打开时可以轻轻地打开盖子,同时自动制动盖子以防止其与粪便体碰撞以产生不期望的打击声, 它被重力自然封闭。
