Patent number: 7025920Abstract: A method of forming a composite shell member for a vehicular sideview exterior mirror assembly includes providing a decorative film substrate and a polymer resin. A shell is formed the decorative film substrate and the polymer resin to form the shell member. A discontinuity is formed in the polymer resin, with the film substrate conformed to the polymer resin to generally follow the edge definition of the discontinuity to form a surface discontinuity in an outer surface of the shell member having substantially the same edge definition of the discontinuity of the polymer resin.Type: GrantFiled: April 26, 2002Date of Patent: April 11, 2006Assignee: Donnelly CorporationInventors: Leo W. Pavao, Tun-Jen Chu

Patent number: 6612708Abstract: A method of forming a mirror housing according to the present invention includes providing a molding apparatus having a molding cavity, placing a film appliqué in the mold cavity and injecting a polymer into the mold cavity over at least a portion of a side of the film appliqué to form a housing wall of the mirror housing wherein the film appliqué adheres to the substrate forming the housing wall. Preferably, the mold apparatus comprises an injection molding apparatus which injects a heated polymer into the mold cavity for forming the housing wall of the mirror housing. The film appliqué preferably matches the color of the vehicle or provides a color accent, wood grain finish, or a metallic finish or the like to provide a decorative appearance to the mirror assembly but without the noise associated with the conventional detachable skull cap designs.Type: GrantFiled: September 9, 2002Date of Patent: September 2, 2003Assignee: Donnelly CorporationInventor: Tun-Jen Chu

Patent number: 6150014Abstract: A coated housing for exterior rearview mirrors for vehicles provides increased gloss and depth of color in appearance, and enhanced resistance to scratching, surface crazing and ultraviolet radiation degradation. The housing is preferably molded from a resinous plastic material in a predetermined color and has a generally transparent polymeric material such as clear urethane or acrylic applied in a thin coating to the unpainted housing. The generally transparent coating may include a tint or particles of metal or mica to enhance the molded housing color and/or appearance. Optionally, adhesion of the coating to the housing may be increased by mixing an adhesion promoting agent in said resinous plastic material prior to molding, or by treating the housing surface after molding and prior to application of the coating. An ultraviolet radiation absorbing, blocking, screening material may be included in the generally transparent polymeric material.Type: GrantFiled: July 6, 1999Date of Patent: November 21, 2000Assignee: Donnelly CorporationInventors: Tun-Jen Chu, Desmond J.

Patent number: 5112736Abstract: A method for the multiplex sequencing on DNA is disclosed which comprises the electroblotting or specific base terminated DNA fragments, which have been resolved by gel electrophoresis, onto the surface of a neutral non-aromatic polymeric microporous membrane exhibiting low background fluorescence which has been surface modified to contain amino groups. Polypropylene membranes are preferably and the introduction of amino groups is accomplished by subjecting the membrane to radio or microwave frequency plasma discharge in the presence of an aminating agent, preferably ammonia. The membrane, containing physically adsorbed DNA fragments on its surface after the electroblotting, is then treated with crosslinking means such as UV radiation or a glutaraldehyde spray to chemically bind the DNA fragments to the membrane through said smino groups contained on the surface thereof.Type: GrantFiled: June 14, 1989Date of Patent: May 12, 1992Assignees: University of Utah, Brigham Young UniversityInventors: Karin D.
