Abstract:
1. A method for manufacturing a circuit board featuring conductive patterns, said method comprising the following steps of: i) affixing a conductive layer, such as a metal foil (3), to a substrate material (1) selectively, such that a part of the conductive layer, such as the metal foil (3), comprising desired areas (3a) for the final product and narrow areas (3c) between the final product's conducting areas, is affixed to the substrate material (1) by means of a bond (2), and removal-intended more extensive areas (3b) of the conductive layer, for example the metal foil (3), are left substantially unattached to the substrate material in such a way that the removable area (3b) is in attachment with the substrate material (1) by not more than its edge portion to be patterned in a subsequent step ii) and possibly by sites which preclude a release of the removable areas prior to a step iii); ii) patterning, by a removal of material, the conductive layer, such as the metal foil (3), from narrow gaps between the desired conducting areas (3a), and from an outer periphery of the area (3b) removable in a solid state, for establishing conductor patterns; iii) removing the removable areas (3b), not affixed to the substrate material (1), from the conductive layer, such as the metal foil (3), in a solid state after the conductive layer's edge area, which was removed from the removable area's outer periphery during the course of step ii), no longer holds the removable areas (3b) attached by their edges to the substrate material.
Abstract:
A reel to reel manufacturing method of electrical bridges, wherein over a substrate (1) made of electrically insulating material is patterned a conductive pattern (2) from electroconductive material, such as metal foil, and from the said electroconductive material is made at least one strip tongue (3) unattached to the substrate, one side of which is attached to the conductive pattern (2), and the said strip tongue (3) is folded over an area insulated electrically from the conductive pattern (2), and the strip tongue (3) is connected electroconductively to a predetermined other part (5) of the conductive pattern (2).
Abstract:
The invention relates to an attachment arrangement (1) for the strings (S) of a stringed instrument, especially a guitar. To the body (100) of the stringed instrument is attached a bridge body (2), first restraining means for restraining the strings (S) from the first end area, second restraining means (3), which are arranged in conjunction with the bridge body (2) for restraining the strings from the second end area. Lever means (5) are arranged in conjunction with the bridge body (2) in order to move the second restraining means (3) for temporarily loosening and/or tightening the strings by means of a lever part (5') included in the lever means (5). The lever means (5) are provided with moving means (6, 7) comprising at least one moving mechanism (7), which is a mechanism separate from the lever means (5). One or more second restraining means (3) are arranged to move with respect to the bridge body (2). The moving means (6, 7) are arranged to transmit the movement of the lever means (5) into the desired movement of one or more restraining means (3).
