Abstract:
PROBLEM TO BE SOLVED: To provide a new mechanism for conveying a web of brittle material from an upstream process to a downstream process when manufacturing or processing of the web. SOLUTION: A mechanism for conveying a web of brittle material 200 includes a guide rail 108 and a non-contact dancer mechanism 102 having a variable position web support plenum adjustably positioned on the guide rail 108. The variable position web support plenum 104 includes an arcuate outer surface 107 with a plurality of fluid vents 103 for emitting a fluid to support the web of brittle material 200 over and spaced apart from the arcuate outer surface thereby preventing mechanical contact and damage to the web of brittle material 200. A support plenum counterbalance 110 is mechanically coupled to the variable position web support plenum 104, wherein the support plenum counterbalance 110 supports at least a portion of a weight of the variable position web support plenum 104 on the guide rail 108.

PROBLEM TO BE SOLVED: To provide a wide band transition element for interconnecting two transmission lines of different kinds. SOLUTION: A wide band interconnection device (10) used for interconnection between a first transmission line (100) and a second transmission line (200), has a substrate (300) with the first transmission line (100) defined at a first side (310) on a first surface (320), the first transmission line (100) including a signal conductor (120) and at least one ground conductor (121 or 122), a signal conductor (220) of the second transmission line (200) defined on an opposite side (340) of the first surface, and a ground plane (260) of the second transmission line (200) on an opposite surface (360), the signal conductor (120) of the first transmission line (100) being electrically connected to the signal conductor of the second transmission line (200)on the first surface. On the opposed surface, the ground plane of the second transmission line has at least one protrusion (261) aligned with the signal conductor of the first transmission line. COPYRIGHT: (C)2004,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide a method for separating a brittle material sheet into a plurality of individual pieces without physical contact with a brittle material layer that has a protective coating on its surface.SOLUTION: A method of separating a sheet 10 of coated brittle material includes the steps of: providing the sheet 10 of layered brittle material comprising the brittle material layer 12 and a coating material 14 adhered to a surface of the brittle material layer; applying laser 18 along a separation line in the sheet 10, thereby cutting the coating material 14; and separating the brittle material layer 12 by inducing a stress fracture in the brittle material layer 12.
Abstract:
PROBLEM TO BE SOLVED: To provide a method of machining sintered electrolyte sheets and fuel cell devices which is used to: cut the electrolyte sheets and/or fuel cell device components to appropriate sizes; trim the edges of the sintered electrolyte sheets or fuel cell devices; and/or form via holes and surface modifications or patterns.SOLUTION: A sintered electrolyte sheet comprises: a body with a thickness of 45 μm or less; and at least one laser machined feature with at least one edge surface having at least 10% ablation. A method of micromachining the electrolyte sheet includes the steps of: (i) supporting a sintered electrolyte sheet; (ii) micromachining said sheet with a laser, where said laser has a wavelength less than 2 μm, a fluence less than 200 J/cm, a repetition rate (RR) between 30 Hz and 1 MHz, and a pulse duration less than 1 μs.

PROBLEM TO BE SOLVED: To improve the lateral shift of a glass ribbon when the ribbon is guided.SOLUTION: A first ribbon-curving subassembly 5a produces a first curved section of the ribbon having, without mechanically contacting the central portion 4 of the ribbon 13, the curvature along the direction 15 of motion of the ribbon. A guide roller 7a applies lateral force to the edges 3a of the ribbon in a position inside or mechanically adjacent to the first curved section of the ribbon. A second ribbon-curving subassembly 12 produces a second curved section of the ribbon having, without mechanically contacting the central portion 4 of the ribbon, the curvature along the direction 15 of the motion of the ribbon. Guide rollers 9a applies lateral force to the edges 3a of the ribbon in a position inside or mechanically adjacent the second curved section of the ribbon. The curvatures of each of the first and second sections stiffen the ribbon to an extent sufficient to permit the guide rollers to laterally move the ribbon without causing it to buckle.
Abstract:
A transverse closed-loop fiber resonator ( 10 ) includes an inner cladding ( 102 ) having a surface ( 300 ) peripherally forming a closed-loop shape for confining light to the surface ( 300 ). The inner cladding has a first diameter thickness ( 104 ) and a first index of refraction profile in a cross-sectional portion of the transverse closed-loop fiber resonator ( 10 ). A ringed-core ( 120 ) corresponding to the closed-loop shape is disposed on the corresponding surface of the inner cladding ( 102 ). The ringed-core ( 120 ) has a second thickness ( 124 ) of material thinner than the first diameter thickness ( 104 ), and a second index of refraction profile greater than the first index of the inner cladding by an index delta in the cross-sectional portion of the transverse closed-loop fiber resonator such that the ringed-core can guide light within the ringed-core traversely around the closed-loop shape.
