摘要： A pitch-type fiber convertible to an activated carbon fiber is infusiblized with an infusiblizing gas and the infusiblized fiber is activated with an activating gas, such as steam, to produce an activated carbon fiber. The waste gas from the infusiblizing step is utilized in a combusting step. The combustible component of the waste gas from the activating step is separated out of the waste gas from the activating step and combusted in the combusting step along with the waste gas from the infusiblizing step. The resulting heat from the combusting step is utilized to preheat the infusiblizing gas and the activating gas and the preheated gases are utilized in the infusiblizing step and the activating step, respectively. This arrangement allows the infusiblizing temperature and the activating temperature to be accurately controlled. Thus, an activated carbon fiber is manufactured continuously without being negatively affected by waste gases from the infusiblizing and activating steps.
摘要翻译：可转化为活性碳纤维的沥青型纤维用不熔化气体进行消融，并且使用活化气体如蒸汽活化不熔化的纤维以产生活性碳纤维。在燃烧步骤中使用来自不熔化步骤的废气。来自活化步骤的废气的可燃组分从活化步骤中分离出废气，并与燃烧步骤中的废气一起在燃烧步骤中燃烧。来自燃烧步骤的所得热用于预热不熔化气体和活化气体，并且预热气体分别用于不熔化步骤和活化步骤。这种布置允许准确地控制灌注温度和激活温度。因此，连续制造活性碳纤维，而不受来自渗透和激活步骤的废气的不利影响。

摘要： A water purifier is composed of a valve main body and a filtration portion, which are coupled to each other in an attachable and detachable manner at the main body side coupling portion and the filtration portion side coupling portion. Consequently, the water purifier filtration portion can be connected to the water purifier main body in a single step with ease in a secure manner, and at the same time, the water purifier filtration portion will not fall off easily even when water with a high water pressure flows in. Also, the water purifier is provided with a concave portion and a sensor packing formed as an integral portion of the concave portion and protruding toward an indicator portion on a wall surface of a cartridge. The indicator portion is provided with a conductive member at a position where it is brought into contact with a first input portion by a water pressure and thereby closes an electric circuit on a circuit board. Consequently, the service life (the rated service cycle) of a filter material (medium) can be notified to the user accurately, and a fluid-tight condition of the indicator portion and the cartridge portion can be ensured.
摘要翻译：净水器由阀主体和过滤部分组成，它们在主体侧连接部分和过滤部分侧联接部分处以可附接和可拆卸的方式彼此联接。因此，能够容易地将净水器过滤部分以一个步骤的方式与净水器主体连接，同时即使在具有高水的水的同时，净水器过滤部分也不容易脱落此外，净水器设置有凹部和形成为凹部的一体部分并朝向筒的壁面上的指示部突出的传感器衬垫。指示器部分在通过水压与第一输入部分接触的位置处设置有导电构件，从而封闭电路板上的电路。因此，可以准确地向用户通知过滤材料（介质）的使用寿命（额定使用周期），并且可以确保指示器部分和盒部分的流体密封状态。
