    摘要: A liquid dilution system which dilutes a sample to be analyzed with a carrier to supply a diluted sample-containing liquid to an analytical measurement apparatus of flow type. The inventive dilution system features simplicity and versatility as compared to conventional automatic apparatus with robot concept, and the present system comprises: a first carrier pump for feeding a first carrier; a sample injection unit for injecting the sample into the first carrier; a main passage for flowing a liquid from the sample injection unit to a detector unit of an analytical measurement apparatus; a branching device located downstream of the sample injection unit for forming a branched passage to remove a liquid mass partially from the main passage; a confluence unit located downstream of the branching unit for confluencing a second carrier; and a second carrier pump for feeding the second carrier to the confluence unit. Dilution and mixing of the sample with a carrier is done twice, once at the sample injection and then again at confluence.

    摘要: Alcohol oxidase is immobilized by bonding an aminosilane coupling agent to a carrier, bonding a multifunctional aldehyde such as glutaraldehyde to an amino group of the aminosilane, washing the carrier to remove free multifunctional aldehyde and bonding alcohol oxidase to the multifunctional aldehyde bonded to the aminosilane. Washing to remove free multifunctional aldehyde enables immobilizing a one molecule thickness of alcohol oxidase on the carrier since free multifunctional aldehyde is not present to cross-link alcohol oxidase molecules together. A thin layer of alcohol oxidase is advantageous when assaying for alcohol since a thin layer does not retain hydrogen peroxide that can deactivate alcohol oxidase. The carrier preferably contains hydroxyl groups and is porous, and can be a silicate-containing carrier such as diatomaceous earth or fire brick. The immobilized alcohol oxidase is used in a column as part of an apparatus for measuring alcohol or as part of an apparatus containing immobilized glucose oxidase for measuring glucose and alcohol.

    摘要: In a method of producing cast coated paper in which a wet coating layer containing as its main components, pigment and adhesive, is heated to permit a gel state to be formed in the layer, or is dried and then rewetted, and then is pressed against a highly polished finishing surface of a heated drum so as to be provided with a glazed finish.The present invention provides an improvement wherein an apparatus for emitting near-infrared radiations into the wet coating layer is employed as a means for permitting a gel state to be formed in the layer or as a means for drying the wet coating layer. The apparatus emits near-infrared radiations having wave lengths of 0.75 to 2.0 .mu.m at the peak wave length of their range which are directed into the wet coating layer.

    摘要: A process for controlling curl in coated papers in which the paper web is coated on one side and is wetted with water on the opposite side by a roll-type water applying apparatus, the water applying operation being carried out under such conditions that the relative difference of the surface speed of the applicator roll from the running speed of the paper web is at least 1000 m/min. and preferably the water applicator roll is reversely turning. Curling of the paper is thereby eliminated.

    摘要: A method of producing cast coated paper in which a rewetted or gelled coating layer is pressed at a linear pressure of above 120 kg/cm against the highly polished finishing surface of a cast coating drum having a surface temperature of above 90.degree. C. Improved cast coating operations are secured by including in the coating composition and/or in the rewetting liquid or the gelling liquid, a releasing agent selected from the group consisting of a phosphate having a fatty hydrocarbon radical with 6 to 22 carbon atoms, an amine-salt thereof and lecithin.
