A method for multi-scale spatio-temporal steering kernel regression may include repeatedly spatially downsampling input video data, thereby obtaining spatially downsampled video data at a coarsest spatial resolution scale. The spatially downsampled video data at the coarsest spatial resolution scale may be temporally upscaled to generate an estimate of temporally upscaled video data at the coarsest spatial resolution scale. The temporal upscaling may be achieved using spatio-temporal steering kernel regression. Estimates of the temporally upscaled video data may be repeatedly spatially upscaled to generate an estimate of the temporally upscaled video data at the original spatial resolution. The spatial upscaling may be achieved using spatio-temporal steering kernel regression.

An object of the present invention is to provide an Al—Zn—Mg—Cu 7000-series Al alloy having high ductility as well as having high strength. For attaining this purpose, an Al alloy having a structure in which an inclusion is not included is produced by reducing an amount of oxygen contained in an Al alloy that is obtained by solidifying a preform resulting from rapid solidification by preferably spray forming a molten metal of an Al—Zn—Mg—Cu 7000-series Al alloy with an inert gas. This Al alloy has, as mechanical properties at an ordinary temperature, a tensile strength of 600 MPa or more, and an elongation of 15% or more when the tensile strength is from 600 MPa or more and less than 800 MPa or an elongation of 10% or more when the tensile strength is 800 MPa or more, and is excellent in cold workability such as rollability.

In a die plate having a hardened surface for sliding a knife, a plurality of WC alloy plates 1b are diffusion-bonded to a base metal 2b, whereby the hardened surface h is formed. A plurality of nozzle holes 4a, 4a . . . are formed on each of the WC alloy plates 1b. Each of the WC alloy plates 1b is formed into a shape having a thickness of 2.5 mm or more and two adjacent edges 20 mm or more in length, wherein each edge is 200 mm or less in length. The die plate has high freedom in an arrangement of nozzle holes to enable a close arrangement of a number of nozzle holes, has an extended life with hardly causing dropping-off of a member constituting a hardened surface, and can be produced with a minimized number of processes.

This invention relates an .alpha.-glucosidase inhibitor mildly inhibiting .alpha.-glucosidase locally present in the micro-villus of small intestine, a composition principally comprising sugar and containing the inhibitor, a food, a sweetener and a feed. The inhibitor delays the digestion of starch, starch-derived oligosaccharides and sucrose, so that the inhibitor has an action of suppressing rapid increase in blood glucose level and an action of suppressing insulin secretion at a lower level. Thus, the inhibitor is useful for the prophylaxis of obesity and diabetes mellitus. The .alpha.-glucosidase inhibitor of the present invention is composed of nucleotide, nucleoside, or base as the structural component of nucleic acid and one or two or more digestible sugars selected from sucrose, starch and starch-derived oligosaccharide. The .alpha.-glucosidase inhibitor mildly inhibits the action of .alpha.-glucosidase as a digestive enzyme in small intestine, and has effects of suppressing rapid increase in blood glucose level and suppressing insulin secretion at a lower level. In combination with digestible sugars, the .alpha.-glucosidase inhibitor is applicable as foods, sweeteners and feeds.
摘要:
An image forming apparatus includes a charging unit for charging an image carrying member contacting the image carrying member as the charging unit for charging the image carrying member. By generating an airflow along the longer direction of a contact portion between the charging unit and the image carrying member, discharge products generated in the neighborhood of the contact portion are removed. It is thereby possible to prevent image degradation and the like caused by accumulation of the discharge products.
