20100288643 | METHOD FOR MANUFACTURING ELECTROFORMED MOLD, ELECTROFORMED MOLD, AND METHOD FOR MANUFACTURING ELECTROFORMED PARTS - In a method of manufacturing an electroforming mold, a first photoresist layer is formed on an upper surface of a bottom conductive film of a substrate, and the first photoresist layer is divided into a first soluble portion and a first insoluble portion. A conductive material is thermally deposited on an upper surface of the first photoresist layer within a predetermined temperature range, to thereby form an intermediate conductive film. An intermediate conductive film is patterned. A second photoresist layer is formed on an exposed upper surface of the first photoresist layer after the intermediate conductive film is removed, and on an upper surface of the intermediate conductive film remaining after patterning. The second photoresist layer is divided into a second soluble portion and a second insoluble portion. Next, the first and second photoresist layers are developed, and the first and second soluble portions are removed. | 11-18-2010 |
20120063273 | Detent escapement for timepiece and mechanical timepiece - A detent escapement for a timepiece capable of decreasing energy loss with respect to a free oscillation of a balance and improving a timekeeping accuracy is provided. In addition, a detent escapement of a timepiece capable of realizing miniaturization and suppressing variations in the accuracy of a finished product due to assembly errors is provided. A one-side actuating spring of a detent | 03-15-2012 |
20120063274 | Detent escapement for timepiece and mechanical timepiece - A detent escapement for a timepiece has an escape wheel and a balance that freely oscillates about a balance staff and includes an impulse jewel that contacts a wheel tooth of the escape wheel and an unlocking stone. A blade includes a locking stone that contacts the wheel tooth of the escape wheel and is supported so as to be capable of approaching to and separating from the escape wheel. A one-side actuating spring contacts the unlocking stone and is elastically deformed along the approaching and separating direction with respect to the blade. The blade is constituted of a blade main body and a blade adjustment portion that is separated from the blade main body. | 03-15-2012 |
20120152748 | Part, timepiece, and manufacturing method of part - A part, a timepiece, and a manufacturing method of the part capable of avoiding the limitations on the member which is used, expanding variation in the design, being easily manufactured, and improving the aesthetic appearance are provided. In an oscillating weight in which a body of the oscillating weight to which anodizing can be applied and a conductive weight are fixed to each other, an insulating layer is interposed between the body of the oscillating weight and the weight. | 06-21-2012 |
20120155228 | Manufacturing method of timepiece part and timepiece part - A manufacturing method of a timepiece part which has small variation in hardness and a metallic luster is provided. Configuration includes a heat treatment process that heat-treats a timepiece part and coarsens a plurality of crystals of titanium or the like, a shape processing process that processes the shape of the timepiece part, an etching process that etches titanium or the like, mirror-finishes the surfaces of each crystal, and makes the normal directions of the surfaces of each crystal to be different from one another, and an anodizing process that performs anodizing on the surface of the timepiece part. | 06-21-2012 |
20120155229 | Decorative part, timepiece, and manufacturing method of decorative part - A decorative part, a timepiece, and a manufacturing method of the decorative part capable of stabilizing and improving the aesthetic appearance while using a fixing member are provided. In an oscillating weight which includes a body of an oscillating weight and screws for fixing the body of the oscillating weight to a weight, the body of the oscillating weight and the screws are a member to which an anodizing can be applied. | 06-21-2012 |
