Abstract:
Proposed are a carbon frame and a method of manufacturing the same capable of improving torsional stiffness. The method includes the steps of: (a) preparing at least two forms; (b) wrapping up the forms with vinyl sheets; (c) laminating carbon prepregs on the vinyl sheets; (d) combining the forms to put the combined forms in a mold; and (e) injecting heat and wind into the vinyl sheets.
Abstract:
A process of overmolding a frame of a portable eyewear electronic device and a frame produced by the process is presented. A frame that includes a first material and includes a releasably mountable feature is attached to the mold in a desired position and does not contact other areas of the mold. The mold is filled with a second material to at least partially encase the frame insert.

Abstract:
A long synthetic resin foam body composed of a thermoplastic resin expanded beads-molded substrate and a frame having displacement regulating sections provided at both ends in the longitudinal or lateral direction of the substrate and a connecting section that connects the displacement regulating sections to each other. The substrate has at least one joint forming portion that divides the substrate in a direction intersecting the connecting section into two or more substrate parts. The joint forming portion has a joint that connects the adjacent two substrate parts to each other and is deformable to permit a relative displacement between the adjacent two substrate parts when the substrate contracts or expands.
Abstract:
The present invention relates to a method for manufacturing a spectacle frame adapted to a spectacle wearer, particularly by means of 3D printing or other additive manufacturing techniques. The present invention provides for this purpose a method comprising the steps of providing a virtual 3D model of a spectacle frame; providing a virtual 3D model of the head of the spectacle wearer which comprises at least a part of the head of the spectacle wearer which is in contact with the spectacle frame when the spectacle frame is being worn; positioning the 3D model of the spectacle frame relative to the 3D model of the head in a virtual environment so that the 3D model of the head intersects the 3D model of the spectacle frame where said part of the head of the spectacle wearer is in contact with the spectacle frame when the spectacle frame is being worn; cutting a portion out of the 3D model of the spectacle frame along the intersecting plane of the 3D model of the spectacle frame and the 3D model of the head; and manufacturing at least a part of the spectacle frame on the basis of the part of the 3D model of the spectacle frame from which the portion has been cut.
Abstract:
A manufacturing process and the semi-finished product of thermoplastic material obtained therefrom, for obtaining products with aesthetic patterns which can be perceived in semitransparency also in depth is disclosed. The process includes: (i) producing at least two initial elements of thermoplastic material with even but different aesthetic patterns, having a different concentration of the dominating coloring, at least the dominating coloring being of the bleeding type in the specific thermoplastic material; (ii) shaping the two initial elements into strips or loaves being of a submultiple width, not below ⅕ of a characteristic dimension of the desired finished product; (iii) inserting at least two of the strips or loaves having different concentration of the dominating coloring, into a workform, arranging them side by side according to a direction of side-by-side arrangement; and (iv) undergoing pressure and heat to allow the melting and hardening of the thermoplastic material into a single body.
Abstract:
A process for making eyeglasses frames (1), where at least one front rim (2) or a pair of sidepieces (3) of the eyeglasses frame (1) is decorated, comprises the steps of decorating a film, inserting the film into the mould (4) and injection moulding the front rim (2) and/or the sidepieces (3) with the film applied to it/them; before the step of injection moulding the front rim (2) and/or the sidepieces (3), there is a step of thermoforming and trimming the film to form and shape the film according to a profile corresponding to a wall (7) of the mould (4), in such a way that the film (5) inserted in the mould is shaped like a surface of the front rim (2) and/or of the sidepieces (3) to be formed.
Abstract:
The present invention provides a method for manufacturing a membrane electrode assembly which improves the reliability of seal, mechanical strength, and handling ability of a solid polymer type fuel cell. The manufacturing method includes: preparing a membrane electrode assembly which differs in the size of the gas diffusion layers at the anode side and the cathode side; and providing a resin frame at the outer peripheral edge of the membrane electrode assembly by molding; wherein the molding includes the use of a mold that keeps penetration of the resin frame material into the gas diffusion layers and/or electrode layers to a minimum and prevents warping of the outer peripheral edges.
Abstract:
Some embodiments provide a lens including a lens body and an optical filter configured to attenuate visible light in certain spectral bands. At least some of the spectral bands can include spectral features that tend to substantially increase the colorfulness, clarity, and/or vividness of a scene. In certain embodiments, eyewear incorporates an optical filter that enhances chroma within one or more spectral bands. In some embodiments, a wearer of the eyewear can perceive the increase in chroma when viewing at least certain types of scenes.
Abstract:
The disclosure relates to trays for the handling and shipping of computer chips, or similar microelectronic devices. The tray include a series of channels, each extending along a width of the tray. The channels include such devices as pins and clips for securing a thermoformed tape. The thermoformed tape includes pockets for storing the various computer chips, or similar microelectronic devices.
