In a culturing method, microalgae are cultured in a culturing solution while a gas containing carbon dioxide is supplied to the culturing solution. In an ion concentration acquisition step, an acquired value of a concentration of hydrogen carbonate ions in the culturing solution is obtained. In an ion concentration adjustment step, in the case that the acquired value does not reside within a set concentration range that is set beforehand, at least one of a temperature or a pH of the culturing solution is adjusted, whereby the concentration of hydrogen carbonate ions in the culturing solution is adjusted to reside within the set concentration range.

A casting mold and a production method thereof with which exfoliation of coating is controlled and liquidity of molten metal can be maintained are provided. This casting moldincludes a surface processing partin which a plurality of groove partsof a grid grooveformed in a surface of a molten metal contact part of a mold materialis coated with a carbon film. In this surface processing part, a width Wof the groove partsis 35 &#x3bc;m or narrower, skewness Ssk of three-dimensional surface roughness is in a range of &#x2212;0.8 to &#x2212;0.2, and indentation hardness of the carbon filmtested by a nanoindenter is 1000 N/mmor higher. With this arrangement, it is possible to optimize the surface processing partin such a manner that a penetration rate of the molten metal (aluminum) is controlled to be low and the coating (carbon film) is unlikely to exfoliate from the groove parts

Casting mold, and production method thereof

The invention is a column contact apparatus for contacting gas with liquid in an upflow in a column container, containing two or more stages of honeycomb structural bodies in the column container in a vertical direction, a space portion formed between the respective stages of the honeycomb structural bodies and a flow-aligning portion as back-flow prevention means provided in the space portion between the respective stages such that the flow-aligning portion is not brought into contact with the honeycomb structural bodies, the flow-aligning portion including a plurality of holes with hole diameters of 0.5 mm to 8 mm.

Column contact apparatus and method for operating the same

A biodegradable wax composition containing a wax as a main component and also containing a biodegradable polymer and a filler and having a moisture permeability of 3 g&#xb7;mm/m&#xb7;24 hr or less at 40&#xb0; C. and 90% RH. The wax is preferably present in an amount of 65 to 95% by weight. The biodegradable polymer preferably has a weight average molecular weight of 200,000 or higher. The polymer is preferably polyisoprene or natural rubber and is preferably present in an amount of 5 to 35% by weight.

Biodegradable wax composition

A process of producing a wax composition mainly comprising a wax, including the step of mixing the wax and a component to be mixed with the wax by applying an external force at a temperature lower than the melting completion temperature of the wax.

Wax composition and method for production thereof

A method of producing a lipped molded article comprising the steps of forming a molded article having an opening portion by papermaking and outwardly curling the peripheral wall portion which constitutes the opening portion to make a lip. The method is characterized in that the inner surface of the molded article is coated with a resin layer to make a multilayer molded article, the part to be curled of the peripheral wall portion of the molded article is impregnated with a liquid, and the part to be curled is subjected to curling processing while or after being heated.

Method for producing flanged molding

A molded article () made predominantly of pulp and comprising a bottom portion () and a body portion (), wherein the angle &#x3b8; between the outer surface of a side wall of the body portion () and the ground contact plane (B) of the bottom portion () is 85&#xb0; or greater, and the height of the body portion () is 50 mm or more.

Formed body

A method of producing a pulp molded article comprising the steps of assembling splits () each having a suction passageway and a papermaking screen () into a papermaking mold (), filling the cavity of the papermaking mold () with a pulp slurry, discharging the liquid component of the pulp slurry through the suction passageway to deposit pulp fiber on the inner side of the papermaking screen () into an undried wet molded article, and dewatering the undried molded article deposited on the inner side of the papermaking screen (), wherein the splits () each have a large number of flow passageways () for feeding a purging fluid for cleaning the papermaking screen (), and the purging fluid is ejected from the outer side of the papermaking screen () toward the cavity through the flow passageways () during the filling with the pulp slurry.

Method of producing pulp moldings

A papermaking mold which includes a papermaking part of a prescribed shape, a peripheral part extending outward from the peripheral edge of the papermaking part, and a net covering the papermaking part and at least part of the peripheral part. A fixing member is disposed on the periphery of the net, and the fixing member is fixed to the peripheral part to fix the net by the fixing member.
