摘要:
A weld portion produced by heat welding and a non-weld portion which does not undergo heat welding are formed on a contact face between an inside face of a stopper portion made of synthetic resin and a surface of a fastener tape. Preferably, a bottom end face of a rear side of the stopper portion is made substantially flush with a rear surface of the fastener tape by heating with pressure. Consequently, embrittlement of the stopper portion is prevented and its fixing strength is secured, thereby eliminating itchy feeling and feeling of discomfort originating from a configuration of the upper stopper portion.

There is provided a double-deck elevator which does not cause any impacts or vibrations on each cage when adjusting the spacing in the vertical direction between upper and lower cages. Loads on an upper support beam from right and left support arms for hoisting and supporting the upper cage are measured by right and left upper measuring units. Similarly, loads on a lower support beam from right and left support arms for hoisting and supporting the lower cage are measured by right and left lower measuring units. Because the magnitude of the loads on the right and left screw shafts can be obtained correctly, any impacts or vibrations caused on each cage can be prevented when adjusting the spacing in the vertical direction by correctly controlling the drive torque output from right and left drive motors.

An artificial cornea comprising an optical element made of an optically transparent material, having a front surface and a posterior surface, and a skirt provided so as to support with surrounding at least a part of the optical element, characterized in that the skirt is provided with a flange on its side facing the interior of eyes during implantation of the artificial cornea and the flange radially protrudes outward from the skirt. The artificial cornea can be well compatible with ocular tissue, prevent leakage of intraocular aqueous humor and intraocular invasion of bacteria, reduce stimulation on palpebral conjunctiva and further, inhibit progression of the down growth, and which has no possibility of reduction in transparency of the optical element due to the down growth as well as detachment and extrusion from the implanted state.

A zipper pull with a cover member, which has a simple structure and can be manufactured at a low cost, can realize a good and stable receiving and holding ability of a pull-tab over a long period of time, and also can prevent swinging between respective component parts, is provided.The cover member of the zipper pull is made of a soft material and has a shape so as to prevent the condition that the pull-tab substantially and directly contacts adjoining portions of an article in the immovable state at the first position. When a slider body and the pull-tub are received in a receptacle, at least the cover member and the slider body are supported and fixed with moving interruption means for interrupting a relative movement of the cover member and the slider body.

The present invention provides a needle-shaped ceramic body and needle-shaped ceramic catalyst body in which a case material is a high specific surface area porous cordierite body that is stable at high temperatures, and also provides methods of producing this needle-shaped ceramic body and needle-shaped ceramic catalyst body. The present invention relates to a needle-shaped ceramic body and needle-shaped ceramic catalyst body in which a base material is a high temperature-stable, high specific surface area porous cordierite body comprising a porous structure having a prescribed porosity and formed of a needle-shaped cordierite crystal phase and further relates to methods of producing this needle-shaped ceramic body and needle-shaped ceramic catalyst body, and by using porous cordierite constituted of needle-shaped crystals as a catalyst-supporting honeycomb structure, the present invention is able to inhibit sintering-induced reduction in the specific surface area. Since a honeycomb can be directly produced as the cordierite sinter itself, an inexpensive product can be provided through the simplifying the prior-art step of coating the interior of the honeycomb.

A slider supplying apparatus, for use with a slide-fastener finishing machine, includes a rail for slidingly supporting a number of sliders in succession from a reservoir, with the opposite wings of each slider body astride of the rail and with a pull tab hanging from the slider body, and a chute defining a guide channel for passage therethrough of the slider bodies and having an upper end portion disposed adjacent to a free end portion of the rail for receiving the successive sliders therefrom. The upper end portion of the chute has a sloping edge engageable with the pull tab of each slider, as the latter slides forwardly on the free end portion of the rail, so as to raise the pull tab perpendicularly to the slider wing. The chute also has a guide slit coextensive with the guide channel for receiving the pull tab of each slider in such raised posture while the slider body is in the guide channel.

An impact resistance enhancing agent for a polylactic acid-based resin, containing a polyglycerol fatty acid ester made from a fatty acid containing at least one member selected from the group consisting of caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, and oleic acid, in an amount of 80% by mass or more of the constituting fatty acids, and a polyglycerol having an average degree of polymerization of from 2 to 40. The polylactic acid-based resin composition containing an impact resistance enhancing agent for a polylactic acid-based resin of the present invention has excellent impact resistance properties, so that the resin composition can be suitably used in, for example, agricultural materials, food wrapping materials, and other wrapping materials, and the like.
