    • An underwater granulating method in which thermoplastic resin material is kneaded and melted by a kneading extruder while the melted resin material is extruded into cooling water from nozzles of a die with its external surface covered with the cooling water, and the resin material extruded in thin strings is cut by a cutter device driven to move along the external surface of the die. The method is characterized by the following steps: increasing the heating magnitude of the die so that the softened resin material filling the neighborhood of the external surface of the nozzles is melted; temporarily stopping the kneading extruder in the heating state where the kneading extruder is supplied with resin material; stopping the cutter device; reducing the heating quantity of the die; covering the external surface of the nozzles with the cooling water in the condition where the resin material filling the neighborhood of the external surface in the nozzles is softened to close the nozzles; and thereafter starting the drive of the cutter device and, at the same time, the drive of the kneading extruder.
    • 一种水下造粒方法,其中将热塑性树脂材料通过捏合挤出机捏合并熔化,同时将熔融的树脂材料从其外表面被冷却水覆盖的模具的喷嘴挤出到冷却水中,并且将树脂材料挤压成细绳 被切割装置切割,该切割装置被驱动以沿模具的外表面移动。 该方法的特征在于以下步骤:增加模具的加热幅度,使得填充喷嘴外表面附近的软化树脂材料熔化; 在捏合挤出机被供给树脂材料的加热状态下临时停止捏合挤出机; 停止切割装置; 降低模具的加热量; 在填充喷嘴外表面附近的树脂材料软化以封闭喷嘴的状态下用冷却水覆盖喷嘴的外表面; 然后开始切割装置的驱动,同时驱动捏合挤出机。

    • In order to obtain a quality image without deterioration owing to radiation noise in inspection using the optical video camera in high radiation environment, an inspection apparatus is formed of an image pick-up unit, an image obtaining unit which fetches a video image that contains a signal (noise) that is substantially independent of each frame obtained by the image pick-up unit, a local alignment unit which locally aligns frames with different time phases for forming the image fetched by the image obtaining unit, a frame synthesizing unit which synthesizes the plurality of frames aligned by the local alignment unit for generating a synthesis frame with an SN ratio higher than the SN ratio of the frame before frame synthesis, and an image output unit for displaying or recording the image formed of the synthesis frame generated by the frame synthesizing unit.
