    摘要: A gasket having a novel structure ensuring both the gas tightness and the low-friction slidability is provided. A sliding portion of the gasket (13) includes at least a first annular projection (17A), an annular recess and a second annular projection (17B) arranged in this order in a direction rearward from a distal portion of the gasket serving as a liquid contact portion. The first projection (17A) is designed so that a first peak appears adjacent the distal portion of the gasket when the gasket is fitted in the syringe barrel (11) and a product α of a contact pressure P1f and a width D1f of the first peak is 0.4 ≤ α ≤ 1.0 as determined by an FEM analysis.

    摘要: Provided is a vacuum devolatilizer for use in a polymer manufacturing or processing plant. The devolatilizer comprises a vacuum chamber having an inlet for a polymer melt, an outlet for a polymer melt, a vacuum port through which volatiles may be removed and a stirrer shaft port for the entry of a stirrer shaft. The stirrer shaft passes through the at least one stirrer shaft port and extends into the vacuum chamber and carries an agitation means. The stirrer shaft seal is associated with each stirrer shaft port for sealing against the stirrer shaft and each stirrer shaft seal has an external portion outside the vacuum chamber. The devolatilizer is provided with a motor located outside of the vacuum chamber for rotating shaft and comprises means for blanketing the external portion of the stirrer shaft seal with a low oxygen content gas or vapor, e.g., nitrogen, helium, steam, or carbon dioxide.

    摘要: To suppress occurrence of a separation of a seal in a valve stem seal including an oil lip and a back pressure lip and fitted to the outer-diameter portion of a valve stem guide. A pressure receiving lip engaging with a guide groove of a valve stem guide is provided in an inner-diameter surface of an inner-diameter rubber portion, and a channel is provided in a portion between a back pressure lip and the pressure receiving lip of the inner-diameter rubber portion so as to guide pressure which has entered from a gap between a valve stem guide and a valve stem to a space between the valve stem guide and the back pressure lip, toward the pressure receiving lip, thereby canceling part of the pressure.
