Abstract: This manufacturing method of a molded surface fastener involves a primary molding step for forming a primary molded body and a secondary molding step for compressing a provisional element of the primary molded body while heating the same. A molding apparatus is provided with a mold member comprising multiple penetration holes and multiple concave portions, whereof each penetration hole communicates to at least one concave portion; in the primary molding step, the molding apparatus is used to form a primary molded body comprising a provisional element having a primary stem portion and a pawl portion is formed from the protruded portion by compressing the provisional element. By this means, it is possible to stably manufacture a molded surface fastener that has an engaging element comprising a pawl portion that projects from the outer peripheral edge of an engaging head portion.

Abstract: A method of forming an architectural concrete structure having a desired look (i.e., color) and texture, wherein the method generally includes pouring a base concrete layer using conventional concrete. A surface concrete mixture is prepared and includes a mixture of sand and small aggregates to give the surface concrete mixture the desired color and texture for the architectural concrete structure. The base concrete layer provides strength and durability to the concrete structure, while the surface concrete layer provides the desired look and texture of the concrete surface. The surface concrete mixture preferably includes small aggregates to create a smooth and uniform texture.

Abstract: The present disclosure provides improved stripfilm based pharmaceutical products (e.g., for enhancing dissolution and bioavailability). More particularly, the present disclosure provides improved systems/methods for fabricating stripfilm based pharmaceutical products by utilizing higher viscosity film forming precursors and drying methods that accomplish improved/faster drying and provide improved/excellent content uniformity of active pharmaceutical agents in the stripfilm based pharmaceutical products. Exemplary systems/methods advantageously use high viscosity, bio-compatible polymeric precursors, (optional use of surface modified drug powders), and convective drying for fabrication of thin films loaded with nano and/or micro sized particles of poorly water-soluble active pharmaceutical ingredients (APIs) to achieve improved active content uniformity and very fast dissolution from poorly water soluble actives, while accomplishing fast drying during the fabrication process. The present disclosure provides for the fast drying (e.g., via low temperature forced convection) of biocompatible polymer films loaded with poorly water-soluble drug nano-particles.

Abstract: A transfer method for expanding pitches of devices includes: providing a first substrate with micro devices having the pitches being a predetermined value in a first direction and a second direction; transferring the micro devices to a first roller by contacting it with the micro devices, wherein a pitch of contact line portions on the first roller is N times of the predetermined value; transferring the micro devices on the first roller to a second substrate; rotating the second substrate by 90 degrees; transferring the micro devices to a second roller by rolling the second roller to contact the micro devices; and then transferring the micro devices to a third substrate to expand the pitch of the micro devices in both the first and the second directions. The portions in contact with the micro devices all have adhesive layers with different adhesion operation windows.

Abstract: The present invention relates to a folded side-leakage-proof arc-shaped elastic sanitary product wainscot and a production line therefor. After two sides of an elastic membrane under a tensile state are compounded with nonwoven fabric strips by hot pressing respectively, the elastic membrane rebounds and resets to impel the nonwoven fabric strips located on two sides of the elastic membrane to form a folded side-leakage-proof side wall. The elastic membrane is in the shape of a concave arc. The present invention has the following advantages: 1, the nonwoven fabric strips may be compounded with two sides of the elastic air-permeable membrane without a hot melt adhesive so as to ensure that the air permeability of the elastic air-permeable membrane and the nonwoven fabric strips is not affected by the hot melt adhesive; and 2, after two sides of the elastic air-permeable membrane under a tensile state are compounded with the nonwoven fabric strips, the elastic air-permeable membrane rebounds to impel the nonwoven fabric strips to form a required elastic folded side-leakage-proof side wall with the rebound and reset of the elastic air-permeable membrane. This side wall not only has a function of preventing liquid from flowing, but also greatly reduces a contact area between a sanitary napkin or a panty-shape diaper and a human body, such that the comfort level of the human body is greatly improved.
