Abstract:
A papermaking additive comprising cellulose nanofibers whose aqueous solution at a concentration of 2% (w/v) has a B-type viscosity (60 rpm, 20° C.) of 500 to 7000 mPa·s, preferably 500 to 2000 mPa·s is used to prepare a paper having improved air resistance and smoothness. This additive is prepared by oxidizing a cellulosic material with an oxidizing agent in the presence of (1) N-oxyl compound (s) and (2) bromide, iodide or a mixture thereof to prepare oxidized cellulose, and finely grinding the oxidized cellulose in a wet condition to convert the oxidized cellulose into nanofibers.
Abstract:
A valve medium processing device for IC coins and coins includes a housing having an insertion slot with an IC coin passage connected to receive IC coins from the insertion slot. A coin passage is also connected to receive coins from the insertion slot. A retaining unit for IC coins selectively stops and releases an IC coin, so that a read and/or write unit can establish a value for the IC coin. An IC coin allocating unit is positioned downstream in the IC coin passage for directing an IC coin to one of an IC coin storage passage and a retain passage. A coin allocating unit allocates a coin to one of a coin storage passage and the return passage.
Abstract:
The present invention aims to provide a process for producing cellulose nanofibers using a 4-hydroxy TEMPO derivative less expensive than TEMPO and a process capable of rapidly producing homogeneous cellulose nanofibers. Wood cellulose can be efficiently converted into nanofibers by a process for producing cellulose nanofibers comprising treating a cellulosic material with an oxidizing agent in water in the presence of a cellulose oxidation catalyst comprising an N-oxyl compound represented by formula 1 below: wherein R1 and R2 are each independently hydrogen or a C1-C6 straight or branched alkyl group; and (i) one of R4 or R5 is —OR, —OCOR or —OSO2R wherein R is a straight or branched carbon chain having 4 or less carbon atoms, and the other of R4 or R5 is hydrogen, and R3 and R6 are methyl, or (ii) R4 is hydrogen, and R5, R3 and R6 are taken together with a piperidine ring to form an aza-adamantane compound having formula 2 below: or a mixture thereof, and a compound selected from the group consisting of bromides, iodides and mixtures thereof to prepare oxidized cellulose, and microfibrillating the oxidized cellulose to convert it into nanofibers.
Abstract:
There is proposed a registration apparatus, a verification apparatus, and a program capable of improving authentication accuracy and an identification data structure capable of improving reliability. A blood vessel line included in an image is divided into a plurality of partial lines on the basis of end points and a diverging point of the blood vessel line. Coefficients of terms corresponding to degrees included in a polynomial equation for an n-th order curve representing each of the partial lines are extracted. Data including points at both ends of each of the partial lines and the coefficients is generated.
Abstract:
A position alignment method, a position alignment device, and a program in which processing load can be reduced are proposed. A group of some points in a first set of points extracted from an object appearing in one image and a group of some points in a second set of points extracted from an object appearing in another image are used as a reference, and the second set of points is aligned with respect to the first set of points. Thereafter, all the points in the first set of points and all the points in the aligned second set of point are used as a reference, and the second set of points is aligned with respect to the first set of points.
Abstract:
An information extraction method, an information extraction device, a program, a registration device, and a verification device that improve authentication accuracy simultaneously with reduction of the amount of information concerning an identification target are proposed. From a plurality of first images obtained from viewpoints in surroundings of a living body portion, common portions of silhouettes of the living body portion that is shown in the images are generated as a first stereoscopic image in a target space. From a plurality of second images obtained from the viewpoints in the surroundings of the living body portion, common portions of silhouettes of an inner surface image of the living body portion that is shown in the images are generated as a second stereoscopic image in the target space. A value representing a shape of a cross section of the second stereoscopic image that has a predetermined positional relationship with respect to a reference position of the first stereoscopic image is extracted as an identification information item.
Abstract:
An image processing apparatus can improve the image quality of images. The image processing apparatus includes a parameter extracting unit that extracts a parameter for expressing the degree of sharpness of each image when a plurality of images are obtained with different degrees of sharpness by decomposing an original image, using input image data, a parameter adjusting unit that adjusts the parameters of the images extracted by the parameter extracting unit so as to make the original image sharp and a generating unit that generates the original image on the basis of the parameters of the images adjusted by the parameter adjusting unit.
Abstract:
Even in a situation in which an image of the back side of an object cannot be captured, the shape of the object can be generated with high accuracy. For individual images captured from the circumference of an object, projection regions projected in an area from the surface of projection in a projective space to a projective plane that is distant from the surface of projection by a predetermined length in a depth direction in a case where the object reflected in the individual images is projected to the projective space from viewpoint positions of the individual images are detected. A portion common to the individual detected projection regions is extracted.

The present invention has been made to be able to highly probably prevent erroneous authentications due to a sham from taking place by means of a simple arrangement. The present invention generates an image signal S2 by shooting a finger, which is a predetermined biological site; generates a blood vessels pattern image in which a pattern of blood vessels showing characteristics of the blood vessels of the finger with respect to the image signal S1 is extracted as a characteristics parameter; calculates an image entropy Him based on the image signal S2; generates registered person identification information Tfv by pairing the blood vessels pattern image and the image entropy Him; and stores it in a flash memory 13 to register.
