    • There are disclosed a method for drying and a method for solid-phase polymerizing a crystallizable polyamide being in an amorphous state which comprises regulating the moisture concentration in the polyamide at its glass transition temperature to at least 0.15% by weight as determined by Karl Fisher titration; heating the polyamide thus regulated at a pressure of at least one arm without reducing the moisture to crystallize the same up to a crystallinity of at least 15% and; further heating the polyamide thus crystallized at a temperature lower than its melting point under reduced pressure with a batchwise heating apparatus. It is made possible according to the method for drying or the method for solid-phase polymerizing the crystallizable polyamide to effect its crystallization without causing tackified sticking or solidified sticking of the polyamide, along with drying or solid-phase polymerization with single apparatus and process, while dispensing with any pretreatment such as surface modification and preliminary treatment equipment intended for crystallization.
    • 公开了一种用于干燥的方法和用于固态聚合处于无定形状态的可结晶聚酰胺的方法,该方法包括将聚酰胺在其玻璃化转变温度下的水分浓度调节至至少0.15重量%,通过Karl Fisher滴定测定 ; 在至少一个臂的压力下加热如此调节的聚酰胺,而不降低水分,使其结晶达到至少15%的结晶度; 在间歇加热装置中,在减压下,在低于其熔点的温度下进一步加热聚酰胺。 可以根据干燥方法或使可结晶聚酰胺固相聚合的方法实现其结晶,而不会引起聚酰胺的粘着粘附或固化粘附,同时用单一设备和方法进行干燥或固相聚合, 同时分配诸如表面改性的预处理和用于结晶的预处理设备。

    • This invention has one object to provide a method of collecting calibration data in radiation tomography apparatus that allows reliable collection of calibration data with a wide detector ring. In order to achieve this purpose, in the method of collecting calibration data in radiation tomography apparatus according to this invention, the number of coincidence events is obtained while the phantom that emits annihilation gamma-ray pairs moves as to pass through an inner hole of the detector ring. Such configuration dose not need the phantom having a width equal or larger than the detector ring, and may realize reliable collection of calibration data. Moreover, it may be considered that annihilation gamma-ray pairs have been emitted in uniform property without depending on positions of the detector ring. As a result, calibration data that is more suitable for removal of a image artifact may be obtained.
    • 本发明的一个目的是提供一种在放射线断层摄影装置中收集校准数据的方法,其允许使用宽的检测器环可靠地收集校准数据。 为了实现这一目的,在根据本发明的放射线断层摄影装置中收集校准数据的方法中,获得符合事件的数量,同时发出湮灭伽马射线对的体模移动通过 探测器环。 这种配置不需要具有等于或大于检测器环的宽度的体模,并且可以实现校准数据的可靠收集。 此外,可以认为,湮没伽马射线对已经以均匀的性质发射,而不依赖于检测器环的位置。 结果,可以获得更适合去除图像伪像的校准数据。

    • Described is an apparatus for the purpose of drying or solid phase polymerization of Polymer particles by batchwise heating the same in an atmosphere of inert gas or under reduced pressure. More particularly, described is batchwise heating apparatus which is capable of efficient production by preventing an objective product from being contaminated with foreign matters accompanying wear of a sealing packing. The batchwise heating apparatus, which heats Polymer particles in a rotating hermetically sealed vessel in an atmosphere of inert gas or under reduced pressure, comprises a vessel equipped with a temperature detection portion capable of measuring temperature even during rotating and a suction/exhaust port inside the vessel capable of reducing pressure and/or replacing with inert gas even during rotating; and a suction/exhaust pipe that is inserted into the vessel so as to communicate with the suction/exhaust port, wherein the rotational sealing portion of the suction/exhaust pipe is installed on the outside of the vessel.

    • A cover assembly includes a support frame (20) fixed to a utility access hole and a rounded cover (10) fitted into the support frame. The support frame is provided in its upper portion with an S-curved inner peripheral surface (20b) having a convex curved surface portion (21) and a concave curved surface portion (22) that continues to the convex curved surface portion and is formed thereabove. The cover has an S-curved peripheral surface (10b) that is substantially complementary in shape to the S-curved inner peripheral surface of the support frame. When the access hole is closed by the cover, the cover is smoothly fitted into the support frame due to a guide function of the S-curved inner peripheral surface of the support frame.
