Title: Cap-equipped container
Inventor: YOSHIHIRO KENJI
IPC: B65D47/12
Filed: 2013-09-12
Abstract: A cap-equipped container is provided with an intermediate plug body (11) which is mounted and fitted in the mouth of the container, and a cap which is removably screwed over the intermediate cap body (11). A built-up section (16) is formed in an engagement groove (15) located below an engagement protrusion section (14). As a result of this configuration, in comparison with a conventional engagement groove (15) having a flat bottom section (15a), despite the formation of the engagement groove (15), rigidity is increased by eliminating thin-walled sections from the engagement groove (15) and from the outer peripheral wall (11j) of the intermediate plug body (1). Consequently, the expansion of the outer peripheral wall (11j) is minimized, and engagement with the engagement protrusion section is ensured. Also, the front end corner (13a) of an engagement ridge (13) is prevented from curling during die separation. Further, the increase in the wall thickness of the engagement groove (15) improves the effect of resistance to ESC (environmental stress cracking) caused by the content or the like.

IPC: A61B6/00
Filed: 2013-09-17
Abstract: In an X-ray photographing device (1) in which an FPD (4) moves independently of an X-ray tube (3), an X-ray irradiated region identification unit (33) identifies an X-ray irradiated region image (G2) from an X-ray image (G1) outputted from the FPD (4) in each X-ray photographing, and an X-ray tube position sensor (31) acquires positional information (P) relating to the X-ray tube (3) in each X-ray photographing. A long image creation unit (35) shifts the X-ray irradiated region image (G2) on the basis of the positional information (P), and creates a long image (G3) by connecting the respective X-ray irradiated region images (G2). Consequently, even if the relative positions of the X-ray tube (3) and the FPD (4) are not constant but vary, the X-ray irradiated region images (G2) can be reliably obtained and accurately connected. Further, timings at which the X-ray tube (3) and the FPD (4) start moving and the movement speeds thereof are not required to be the same, and thus control becomes easier.
