Patent number: 9566148Abstract: Metal foils, wires, and seamless tubes with increased mechanical strength are provided. As opposed to wrought materials that are made of a single metal or alloy, these materials are made of two or more layers forming a laminate structure. Laminate structures are known to increase mechanical strength of sheet materials such as wood and paper products and are used in the area of thin films to increase film hardness, as well as toughness. Laminate metal foils have not been used or developed because the standard metal forming technologies, such as rolling and extrusion, for example, do not lend themselves to the production of laminate structures. Vacuum deposition technologies can be developed to yield laminate metal structures with improved mechanical properties. In addition, laminate structures can be designed to provide special qualities by including layers that have special properties such as superelasticity, shape memory, radio-opacity, corrosion resistance etc.Type: GrantFiled: January 31, 2005Date of Patent: February 14, 2017Assignee: Vactronix Scientific, Inc.Inventor: Denes Marton

Patent number: 9554894Abstract: An intraocular lens insertion device and a cartridge which enable the intraocular lens to be inserted into an eye more stably and easily than ever before. A supporting portion 102 of an intraocular lens 100 arranged on a lens-advancing side in a lens-advancing direction x is pressed against a protrusion 21 so as to be bent backward. Thus, releasing the intraocular lens 100 from a nozzle portion 13 is allowed to begin with the releasing of a curved portion of the supporting portion 102 that has become U-shaped and hard to move freely. As a result, there can be provided an intraocular lens insertion device and a cartridge which enable the intraocular lens 100 to be inserted into an eye more steadily and easily than ever before.Type: GrantFiled: June 3, 2009Date of Patent: January 31, 2017Assignee: Hoya CorporationInventor: Masanobu Inoue
