    • A sample tube of a sampling valve is moved up and down by a cylinder. When the sample tube is moved downward, a sample inlet opposes a stored sample, and the sample can be extracted. When the sample tube is moved upward, the sample inlet opposes a cleaning liquid path. Thus, cleaning liquid is fed into the cleaning liquid path from a cleaning liquid supply port of a cleaning pipe. The cleaning liquid flows within the sample tube from the sample inlet, and flows out from a sample discharge port. Thus, an entire interior of the sample tube can be cleaned. In a sample extracting device using the sampling valve, a state in which no air or impurities are mixed in the sample can always be maintained, such that stable extraction can be carried out.
    • 采样阀的样品管由气缸上下移动。 当样品管向下移动时,样品入口与存储的样品相对,并且可以提取样品。 当样品管向上移动时,样品入口与清洁液体路径相反。 因此,清洗液从清洗管的清洗液供给口送入清洗液路径。 清洗液从样品入口在样品管内流动,从样品排出口流出。 因此,可以清洁样品管的整个内部。 在使用采样阀的样品提取装置中,可以始终保持在样品中不混合空气或杂质的状态,从而可以进行稳定的提取。

    • A method of producing a silver halide photographic emulsion in which a silver ion concentration in precipitation of a silver halide emulsion in a precipitation bath is controlled, wherein a precipitation bath in which stirring is conducted rapidly and uniformly, and crystal formation and crystal growth are uniformly performed is used, the method comprises the steps of: in a start period of precipitation, quantitavely adding a silver nitrate solution and a halogen salt solution at a constant ratio flow rate; when an E.sub.Ag value reaches a designated E.sub.Ag value region in the vicinity of a preset target E.sub.Ag value, starting a control of an adding rate of the halogen salt solution by using a controller which has an operation period equal to or shorter than 1 sec.; and after holding a tuning parameter of a proportional, integral and differential (PID) action controller to a minimum response level, conducting a control in which the tuning parameter is switched to an optimum control tuning parameter which corresponds to the preset target value and a solute rate of silver/halogen ions to be added.
    • 一种卤化银照相乳剂的制备方法,其中控制沉淀浴中的卤化银乳剂沉淀中的银离子浓度,其中快速且均匀地进行搅拌的沉淀浴以及晶体生成和晶体生长均匀 所述方法包括以下步骤:在起始沉淀期间,以恒定比例流量定量加入硝酸银溶液和卤素盐溶液; 当EAg值达到预设目标EAg值附近的指定EAg值区域时,通过使用具有等于或小于1sec的操作周期的控制器开始控制卤盐溶液的添加率; 并且在将比例积分微分(PID)动作控制器的调谐参数保持在最小响应水平之后,进行将调谐参数切换到对应于预设目标值的最佳控制调谐参数的控制和溶质 银/卤离子的添加​​速率。
