Abstract: A conveyance chain comprises a plurality of link plates alternately coupled and conveying plural tool pots each holding a tool. The plurality of link plates include an inner link plate and an outer link plate each including a rotation stop hole that stops a rotation of the tool pot and a rotation permit hole located upstream from the rotation stop hole with respect to a conveyance direction that permits a rotation of the tool pot. The plurality of tool pots includes a first tool pot and a second tool pot, the first tool pot is inserted through a rotation stop hole of the inner link plate and a rotation permit hole of the outer link plate, and adjacent to the first tool pot, the second tool pot is inserted through a rotation permit hole of the inner link plate and a rotation stop hole of the outer link plate.

Abstract: An object of the present invention is to obtain a capsule for treating ulcerative colitis which, when a capsule containing indigo is orally administered, acts more effectively than conventional ones and has less side effects of hepatotoxicity by not easily disintegrating in the stomach and small intestine but only in the large intestine. The present invention relates to a capsule for treating ulcerative colitis which disintegrates locally in the large intestine, comprising a drug-containing content, a protective layer coating the content and a film formed outside the protective layer, which are arranged concentrically, wherein the content is a content in which indigo, which is a drug for treating ulcerative colitis, is dispersed or dissolved, and the film is locally disintegrated in the large intestine.

Abstract: A gasket 100 is configured to seal a gap between an installation member 200 and a fixation member 300 which are fixed to each other. The gasket 100 has an annular gasket main body 11 configured to be fitted into an annular groove 210 provided in the installation member 200 and configured to be in close contact with a bottom surface 210a of the annular groove 210 and with an end surface 310 of the fixation member 300, and an auxiliary seal portion 12 extending from the gasket main body 11 toward an opposite region, which is opposite to a sealed region. The auxiliary seal portion 12 is configured to be in close contact with an end surface 220 of the installation member 200 on the opposite region side of the annular groove 210 and with the end surface 310 of the fixation member 300.

Abstract: A gasket is provided which is intended to improve its sealing performance by attaining a further stabilization of the posture thereof in a groove.

Abstract: There is provided a tool holding and conveying chain adapted to securely lock and position a tool pot, i.e., a connecting pin, to a pin hole of either an outer or inner link plate so that the tool pot does not to turn and to achieve steady and smooth attachment and removal of a tool in and out of the tool pot with a simple attachment structure. The tool pot has a pair of positioning flat portions formed by cutting a link plate attaching outer circumferential region of the tool pot and the outer link plate has a pair of positioning cooperative flat portions formed so as to bulge out of an inner circumference to a center of a pin hole. The positioning flat portions of the tool pot is fitted into and locked by the positioning cooperative flat portions when the tool pot is attached in the link plate.

Abstract: Masonry units (10) are integrally assembled by tightening forces of bolts (60) and nuts (70), in a condition that interlayer metal plates (50) are interposed between the masonry units. A basic form (11) of the masonry unit is contained in a mold for forming the masonry unit. A space (98) for fluidic covering material, which is chargeable with the covering material, is defined between upper and lower faces of the form (11), and the fluidic covering material is charged in the space. The upper and lower faces of the masonry unit are covered with the solidified covering material (12). According to the present invention, high dimensional accuracy of the masonry unit can be ensured, and efficiency of the production process of the masonry units is promoted to improve productivity of the masonry units.

Abstract: The invention provides a process for producing gaskets that is capable of improving the wettability of the metal surface to thereby enhance the tackiness when rubber is anchored to a metal core material without using an adhesive.
