Abstract: This invention provides a chromatographic apparatus comprising an introduction part for a carrier gas as a main mobile phase medium, a sample injection part, a separation column comprising a stationary phase formed by coating a polymeric material, a part for housing the separation column, and a detector. The sample injection part is provided between the carrier gas introduction part and the inlet of the separation column. The chromatographic apparatus further comprises a solvent introduction means for adding a liquid solvent as a second mobile phase medium to a carrier gas and mixing them together, a mechanism for regulating the amount of the carrier gas introduced and the amount of the solvent added, and a mechanism for regulating the temperature of each flow passage. A plurality of clogging liquid stoppers, of which the liquid film thickness is equal to the inner diameter of a capillary column, are partly provided at predetermined intervals within the column in a longitudinal direction of the column.

Abstract: In a bottle 1 having a waist groove 61 and a grasping recess 63 nearly in the center of the height direction of a body portion 4 for imparting the sloped surface of a waist portion with necessary strength and restoring capability so that the denting and deformation of the sloped surface of the waist portion are prevented and for forming an easily graspable container even if it is a thin-wall container of which the weight has been decreased, a finger receiving recess 62 having the form of a convex curved surface toward an inside of the container is formed in a region including a container bottom portion side connecting face 61c of the waist groove 61.

Abstract: There is provided an alkaline cleaning of aluminum alloy, in which the attained corrosion resistance is equal or superior to the acidic cleaning agent, and which mitigates the disadvantages of the acidic cleaning agent, such as corrosion of plant, processing of the waste liquid, and energy cost, and which attains improved productivity. The cleaning liquid from 0.5 to 40 g/L in total of one or more alkali builders selected from alkali metal hydroxide, alkali metal carbonate, inorganic alkali metal phosphate and alkali metal silicate, from 0.2 to 10 g/L of one or more of organic phosphonic acid and its salt (A), from 0.001 to 2 g/L of one or more metallic ions (B) selected from metallic ions having from 5.0 to 14.0 of stability constant with the organic phosphonic acid and its salt, and from 0.1 to 10 g/L of surfactant. Particularly, the weight ratio of (A):(B) is in a range of from 100:0.05˜20.

Abstract: Provided is a container 1 for inspection which stores and pours out contents therein, and the container is provided with a container main body 2 having a mouth portion 22 formed thereon, a cover portion 3 attached to the mouth portion 22 to seal the container main body 2, and an opening cap 4 attached to the cover portion 3. The cover portion 3 has a closing wall 34 for closing the mouth portion 22, and the opening cap 4 is provided with an pouring outlet 421, and a cutting portion 431 for cutting the closing wall 34. When the opening cap 4 is attached to the cover portion 3, the cutting section 431 cuts the closing wall 34 to enable pouring out the contents. Thus, in the provided container 1 for inspection, sealing properties of the container main body 2 are ensured by the cover portion 3, and the closing wall 34 of the cover portion 3 is cut by the opening cap 4 attached to the cover portion 3 without removing the cover portion 3, whereby the contents can be poured out.

Abstract: An apparatus for flowing and filling liquified gases, which fuctions to flow and to fill liquified bases into cans from a liquified gas storage tank immediately before seaming of the cans. The apparatus includes a solenoid for attracting an upper portion of a needle of a flow valve formed from a needle valve to open and clode the valve. A pulse motor adjusts an opening-degree of the valve. A valve opening-degree detecting device detects the opening degree. A direction changing nozzle is formed with a nozzle opening obliquely descended in a direction of transporting a can, below the flow valve. A line speed and a balve open amount in a high speed region and a low speed region are respectively set to thereby obtain a line speed/valve opening-degree conversion table, on the basis of which an opening-degree of the valve can be controlled following the line speed.
