摘要:
By the use of a binder comprising (a) 40 to 70 wt % of a water-soluble amide material and/or water-soluble amine material and (b) 25 to 60 wt % of a polyamide resin component substantially composed of a polyamide resin material having 10 carbon atoms or more on average between amido groups, a molded article is produced by metal powder injection molding.From such a molded article, the water-soluble amide material and/or water-soluble amine material is eluted by a water-based solvent and then, the polyamide resin component is removed by heating.
摘要:
A water solvent extraction degreasing method capable of reducing degreasing time without consideration of abrupt decomposition/vaporization and swelling caused by heat. An organic binder is removed from a molded product that is produced by a powder material mixed with the organic binder and this organic binder contains at least one water-soluble organic compound and at least one water-insoluble thermoplastic resin. The degreasing step of this method includes a water solvent extraction step for extracting the water-soluble organic compound from the organic binder contained in the molded product, using water as a solvent.
摘要:
A low-cost thermal decomposition degreasing method capable of drastically reducing the time required for a degreasing process which involves heating, vaporization and thermal decomposition, while assuring the shape retention property of an injection molded product during degreasing. The degreasing process comprises: (i) a first step wherein a molded product placed under a reduced pressure less than or equal to atmospheric pressure is heated at a temperature lower than the melting point of a thermoplastic binder so that the thermoplastic binder partially evaporates by 5 wt % or more, and then the molded product is further heated at a temperature lower than higher one of the melting points of a more volatile organic compound and a thermoplastic resin whereby the thermoplastic binder further evaporates by 10 wt % or more, and wherein the final temperature is set to 200.degree. C. or less; and (ii) a second step wherein the molded product is heated to a temperature higher than or equal to the highest one of the melting points of thermoplastic binder components at a pressure higher than or equal to atmospheric pressure in an atmosphere of gas inert relative to a powder material constituting the molded product.

The present invention provides a double-stranded RNA which inhibits replication of influenza B viruses by RNA interference, in which the double-stranded RNA comprises an RNA having 19 to 25 nucleotides homologous with a part of an mRNA transcribed from a genomic RNA of the influenza B viruses and an antisense RNA thereof.
摘要:
The present invention provides a method and system for analyzing a network of biological functions, such as transcriptional factors, structural genes, cellular markers, cell surface markers, cell shapes, organelle shapes, cell mobility, enzyme activities, metabolite concentrations, and localization of cellular components, in a biological entity such as a cell. Particularly, an object of the present invention is to provide a system and method for presenting biological information in a global manner without modification where the cell is considered a complex system.
摘要:
It is intended to provide a method and system for carrying out data production with respect to the actual status of cells as a profile. It is also intended to provide a system and method for presenting time-lapse and/or real-time information of cell interior directly, or as it is, from the viewpoint of a complex system. It is further intended to provide a method of presenting a digital cell. Thus, there is provided a method of producing profile data relating to cell information, comprising the step (a) of arranging cells in an immobilized form on a support and the step (b) of monitoring over time biological factors on or inside the cells or an aggregate thereof, thereby producing profile data for the cells. Furthermore, there is provided a method of producing a digital cell, comprising procuring experimental data by the use of the above method.

摘要:
A bearing seal includes: a ring-shaped outer seal portion; a ring-shaped inner seal portion provided inside the outer seal portion; a connecting portion for connecting the inner seal portion and the outer seal portion; and a ring-shaped rigid portion provided at the connecting portion. The outer seal portion, the inner seal portion, and the connecting portion are integrally formed of the same material consisting of an elastic material. The inner seal portion has rigidity higher than that of the outer seal portion, and has a ring-shaped seal surface gradually approaching a ring center axis of the inner seal portion while extending from a ring-shaped base end side connected to the connecting portion toward a distal end side.The inner seal portion is formed in a tapered cylindrical shape having the ring-shaped seal surface on an inner peripheral surface thereof, and has a thickness which gradually decreases from the base end side toward the distal end side. The inner seal portion includes only one inner seal portion.
摘要:
The present invention provides a method for deriving an upstream or downstream component of a component necessary for phenotypic alteration of a living organism, the method comprising the steps of: specifying a pathway of interest related to the phenotypic alteration and a reference pathway different from the pathway of interest, and specifying a stimulant of interest and a reference stimulant which respectively stimulate the pathway of interest and the reference pathway; giving the stimulant of interest to the living organism to identify a collection of components of interest necessary for the phenotypic alteration; giving the reference stimulant to the living organism to identify a collection of reference components necessary for the phenotypic alteration; calculating an intersection between the collections of the components of interest and the reference components; and calculating a differential collection by subtracting the intersection from the collection of components of interest.
