The present invention provides implant devices configured to become anchored within tissue so that they do not migrate despite experiencing aggressive migration forces applied by the highly dynamic movement of muscle tissue that surrounds them. Additionally, methods for placing the devices so that they remain securely anchored within the tissue are provided. The devices are comprised of a flexible body, preferably formed from a helical wound spring. In a preferred embodiment the spring is wound from a ribbon-like filament having series of barbs or ridges formed along the proximal facing edge of the wound ribbon. The ribbon-like filament may be etched from a flat sheet of material, having barbs formed along one edge. The filament may then be wrapped into a helical coil shape to take the form of an implant having barbs formed along the proximally facing edge of each coil to resist migration.

In anodic bonding between a conductor or semiconductor and glass, in order to attain good adhesion at a lower bonding temperature than usual and improve the toughness at its boundary to obtain higher reliability for a bonded portion even in a case where bonded members are warped or dust is present at the bonding boundary, a soft metal film is formed on the surface of a conductor or semiconductor on which an active metal film having high reactivity with oxygen is formed, whereby a warp or dust, if any, can be absorbed by the deformation of the soft metal film, thereby to improve the adhesion at the boundary. Adhesion at the bonding boundary is improved even at a low bonding temperature of, e.g., about 200° C. Further, the toughness at the bonding boundary can be improved to increase reliability by roughening the bonded surface on the side of the glass.

The invention discloses a self-aligning liquid crystal display panel and a manufacturing method thereof. In the manufacturing method of the self-aligning liquid crystal display panel, the passivation layer of a TFT substrate is provided as an organic insulating film and organic substances on the surface of the organic insulating film are destroyed by a special treatment method so as to generate -OH and -COOH by decomposition, which facilitates the formation of hydrogen bonds between auxiliary alignment agent and the organic insulating film and increases the anchoring ability of the auxiliary alignment agent on the organic insulating film and solves the problems of the alignment force difference and the bright and dark line displaying defects caused by the surface difference between a pixel electrode and the passivation layer, and achieve even alignment. In addition, the display panel and the manufacturing method thereof further have the advantages that alignment film materials are saved, the related processes of alignment films are eliminated, and further the production cost of the liquid crystal display panels is reduced. The self-aligning liquid crystal display panels are obtained by the above method, achieve the even alignment and have a better displaying quality and do not need arranging the alignment films, so the production cost is lower.

The invention discloses a preparation method for blocked waterborne polyurethane. The method is characterized in that polyurethane is modified by synthesizing a partially-esterified styrene-maleic anhydride copolymer carrying hydroxyl, so that a polyurethane chain plays a role in strongly anchoring organic pigment particles, the dispersion stability of the organic pigment particles in waterborne polyurethane emulsion and the adhesion of a pigment by a waterborne polyurethane adhesive during inkjet curing are facilitated, and the friction resistance and washing fastness are improved. Meanwhile, the polyurethane is subjected to active blocking, so that an unblocked NCO group can react with an OH group on fiber during heating curing after digital printing waterborne paint ink prepared by taking the blocked waterborne polyurethane emulsion prepared by the method as an adhesive is directly jetted onto a fiber fabric, thereby remarkably improving the color fixing firmness and friction resistance. A printed pattern is bright in color, and is soft in handfeel.
