Abstract: An image processing apparatus includes a blurring processing unit configured to generate a blurred image by applying a two-dimensional Gaussian filter having a filter size of S1×S2 to an input image, and a resolution conversion unit configured to generate, from the blurred image, a converted image of which a resolution is converted at a first conversion magnification R1 and a second conversion magnification R2. When the blurring processing unit sets a relation of S1>S2, a relation of R2>R1 is established, and when the blurring processing unit sets a relation of S2>S1, a relation of R1>R2 is established. Here, standard deviations of the Gaussian filter are set to be standard deviations ?1 and ?2, respectively. The blurring processing unit applies the Gaussian filter having a filter coefficient of ?2=?1 to the input image when S2 is different from S1.

Abstract: The present invention provides a method for measuring connection strength of a measuring object in which a first measurement member and a second measurement member are connected, the measuring object being an object in which the first measurement member in the form of a cylindrical member or a cup member, and the second measurement member in the form of a cylindrical member or a cup member, are connected at respective openings thereof, the method including: fixing, as step 1, the first measurement member by enclosing a circumferential wall thereof from the outer circumferential wall thereof, and axially supporting but to fixing an annular end surface of an opening of the second measurement member; holding in midair, as step 2, the first measurement member fixed in step 1; and pulling away, as step 3, the first measurement member until connection portions of the first measurement member and the second measurement member are separated.

Abstract: A rolling-swaging tool for closing an opening of a cylindrical housing includes: a support shaft connected to a driving body; rotating shafts extending in directions orthogonal to the support shaft; and swaging portions, each of which being attached to each of the rotating shafts. The swaging portions have, an annular first swaging portion having a minimum thickness and a maximum outer diameter, a disk third swaging portion having a maximum thickness and a minimum outer diameter, and an annular second swaging portion having a thickness between the minimum thickness and the maximum thickness and an outer diameter between the maximum outer diameter and the minimum outer diameter. The tool also has a first annular inclined surface provided between the annular first swaging portion and the annular second swaging portion, and a second annular inclined surface provided between the annular second swaging portion and the disk third swaging portion.

Abstract: The present invention provides a closing structure which closes, with an igniter, an opening of a cylindrical housing used in a gas generator, the cylindrical housing provided with a stepped surface formed on an inner side of a circumferential wall on the side of the opening, and a distal end circumferential wall extending from the stepped surface to the opening, the igniter having an igniter main body, and an igniter collar surrounding part of the igniter main body and having an annular plate portion with a maximum outer diameter and a circumferential wall excluding the annular plate portion, the annular plate portion including, a first annular surface facing the ignition portion of the igniter main body, a second annular surface facing the electroconductive pin of the igniter main body, and an annular circumferential surface between the first annular surface and the second annular surface, a first annular circumferential edge at the boundary between the first annular surface and the annular circumferential
