摘要:
A concrete composition for underwater use contains about 0.1 to 4% by weight based on cement content of a water soluble vinyl polymer containing vinyl units having sulfonic groups. The concrete composition is easy to mix and prevents separation of concrete composition constituents as it is laid under water.
摘要:
A cement composition is provided which has the property of being inseparable in water, having improved strength and no effect in delaying setting time or reducing strength. It is produced at a cheaper cost by reducing the amount of a polyacrylamide compound to a considerable great extent. The polyacrylamide compound is present in an amount of 0.1 to 3% by weight based on the weight of cement, when a dialdehyde is added thereto.

A concrete composition is provided which has the property of being inseparable in water and no effect in delaying setting time or reducing strength. A polyacrylamide partial hydrolysate having a molecular weight of one million or higher and a hydrolysis degree of from 0.5 to 20% moles is present in an amount of 0.5 to 4% by weight based on the cement constituent proportion.
摘要:
A pressure water absorption inhibitor for lightweight aggregates which comprises an aqueous dispersion of a polymeric substance having a viscosity which permits the aqueous dispersion to enter the fine pores in the surface layer of a lightweight aggregate and which dispersion is capable of being thickened to a viscosity of not less than 50 times the viscosity before thickening by elevation of the pH.
摘要:
A compound represented by the formula [I]: or a pharmacologically acceptable salt or ester thereof, wherein Ring A represents a five-membered aromatic heterocyclic group or the like fused with a non-aromatic ring group, which may be substituted, Ring B represents a phenyl group or the like which may be substituted, X1 represents a single bond or the like, R1 and R2 each represent a C1-6 alkyl group or the like, m represents an integer of 0 to 3, and n represents an integer of 0 to 2, is effective as a therapeutic agent for a disease caused by Aβ.
摘要:
In a mobile terminal provided with an encoded data recording function, there is assumed a condition in which a picture frame transmitted from the terminal of a communication partner is reproduced by means of decoding processing and is displayed on a LCD (34) during wireless TV phone communication. In this condition, when a user carries out a picture recording start operation, display picture data reproduced by means of decoding processing in the multimedia processing section (24) to be displayed on the LCD (34) are recorded in a main recording section (26).
摘要:
A main body controller provided in an image forming apparatus receives a VDP job from an external computer, and arranges image data of a reusable object and a variable object, which correspond to the VDP job, on a page for printout. An inspection controller performs inspection processing for printed matter for each page, and the main body controller preferentially stores image data of the reusable object, which corresponds to the page for which the printing has been determined to be defective as a result of inspection processing, in a cache unit. The main body controller acquires the reusable object, which corresponds to the page for which the printing has been determined to be defective, from the cache unit, and executes page reprint processing using the acquired reusable object.
摘要:
A manufacturing method of a plugged honeycomb structure including attaching a transparent sheet to an end face of a honeycomb structure; picking up an image of the end face; with respect to cells positioned at other than outermost peripheral portion of a honeycomb structure (usual cells), subjecting the picked-up image to image processing, recognizing positions to be plugged on said sheet, and with respect to cells positioned at outermost peripheral portion (outermost peripheral cells), positions of the cells are recognized based on an average cell pitch calculated from the positions of the cells, subjecting to a perforation treatment based on the recognized positions of the sheet, submerging an end portion into a plugging slurry in which a material of the plugging portions is slurried, filling holes made at the respective sheet with the slurry to form the plugging portions.
摘要:
There is provided a honeycomb structure including: porous partition walls separating and forming a plurality of cells extending between two end faces, and an outer peripheral wall formed unitarily with the partition walls. The cells include outermost peripheral portion partial cells each locating in an outermost peripheral portion of the honeycomb structure and having an incomplete cell cross section, a part of which is brought into contact with the outer peripheral wall, and complete cells each having a complete cell cross section other than the outermost peripheral portion partial cells. The complete cells and the outermost peripheral portion partial cells having plugging portions formed on one end portion so that an entire end face of the honeycomb structure shows a checkerwise plugging pattern, and the depth of the plugging portions in the outermost peripheral partial cells is smaller than that of the plugging portions in the complete cells.
摘要:
A compound represented by the formula (I): or a pharmacologically acceptable salt thereof, wherein Ar1 represents an imidazolyl group or the like which may be substituted with a C1-6 alkyl group, Ar2 represents a phenyl group or the like which may be substituted with a C1-6 alkoxy group, X1 represents a double bond or the like and Het represents a triazolyl group or the like which may be substituted with a C1-6 alkyl group or the like, is effective as a therapeutic or prophylactic agent for a disease caused by Aβ.
