The invention relates to a method for operating a drywall screwdriver (1), an electric motor (3) of the drywall screwdriver (1) being driven by means of a plurality of temporally spaced individual pulses (11) in order to allow a user to influence the countersinking of a screw (7) in a workpiece (10) in pulses. According to the invention, a screwing tool (8) that is mechanically coupled to the electric motor (3) and can be brought into engagement with the screw (7) is moved further by a predetermined angle of rotation (a) with each of the individual pulses (11).

A fiber optic device includes a support having one or more optical fibers coupled to the support and a base that includes one or more optoelectronic devices. The support is coupled to the base such that one or more of the optoelectronic devices are optically coupled to one or more of the optical fibers. A portion of the one or more optical fibers that is in contact with the support may be bent and one or more of the optoelectronic devices may be optically coupled to the bent portion of one or more of the optical fibers.

A method for forming a tool for creating a formed component includes providing a forming tool having a core and cavity with respective core and cavity shutoff bands. Core and cavity finished parting planes are determined, wherein the engagement of the core and cavity finished parting planes defines a forming cavity. Rough portions of the core and cavity shutoff bands are removed to define respective rough parting planes. The respective rough parting planes are offset by approximately 130 microns from the respective core and cavity finished parting planes. The core and cavity are semi-finished to relieve stress within the core and cavity. The core and cavity shutoff bands are fine cut so that outer surfaces of the core and cavity shutoff bands are equal to the respective finished parting planes. The engagement between the core and cavity outer surfaces is substantially free of gaps.

The invention relates to a method for producing a sealing element, in particular a sealing ring, for sealing a connection of two flanges, of which at least one has a non-plane sealing surface, wherein at a plurality of circumferential positions (UP1 to UPn) lying in the circumferential direction of at least one flange, preferably of both flanges, in particular circumferential positions that are equidistant from each other, a distance value between the sealing surfaces of the flanges facing each other is determined at several locations that lie one behind the other in a direction perpendicular to the circumferential tangent, in particular in a radial direction, for each of the circumferential positions and a single thickness value is determined from the several distance values of each circumferential position and a sealing element is produced in dependence on all thickness values, which depend on the circumferential position, which sealing element has a thickness that depends on the circumferential position, which thickness is constant at each of the circumferential positions corresponding to the flanges in a direction perpendicular to the circumferential tangent, in particular in the radial direction, and corresponds to the determined thickness value of the respective circumferential position.

According to certain embodiments, a method comprises disposing a first nanofiber portion of a nanofiber and a first assisting fiber portion of an assisting fiber into a ferrule of a connector. A second assisting fiber portion is heated. The nanofiber and assisting fiber are moved such that a portion of the heated assisting fiber portion is disposed within the ferrule. According to other embodiments, a method comprises placing a fiber within a ferrule of a connector having a fixed point such that a fiber center is a fiber distance away from a receptacle center. The fiber distance between the fiber center and receptacle center is measured. An angular offset between the fixed point and fiber center is measured about the receptacle center. A rotation angle for the fiber distance and angular offset is determined. The ferrule is rotated relative to the connector according to the rotation angle.
