摘要： A method of making a spiral spring from a strip of spring material comprises the steps of forming an end portion of the strip of spring material so that the end portion is set to form a spiral coil and the remainder of the strip is substantially straight or is set to coil spirally around the said coiled end portion with a radius of curvature substantially greater than that of the coiled end portion, and then backwinding at least the said coiled end portion.

摘要： The application provides methods for designing a pre-activated arch expander, methods and systems for manufacturing a pre-activated arch expander, and pre-activated arch expanders. The method for designing a pre-activated arch expander includes: determining a target arch expansion parameter based on a digital model of an initial dental jaw in an initial dental arch form; determining a digital model of a target dental jaw in a target dental arch form based on the digital model of the initial dental jaw and the target arch expansion parameter; and designing a digital model of a pre-activated arch expander based on the target arch expansion parameter and the digital model of the target dental jaw.

摘要： A heating coil production system for producing heating coils for electronic vaporizers includes a conductor that has a first end and a second end. An anchor is provided and the anchor is selectively positioned on a support surface. The second end of the conductor is removably coupled to the anchor. A rotation unit is provided and the rotation unit is selectively positioned on the support surface and the rotation unit is selectively turned on and off. The first end of the conductor is selectively coupled to the rotation unit and the rotation unit twists the conductor into a coil when the rotation unit is turned on. The resulting coil is positioned in an electronic smoking device for a heating element.

摘要： The present disclosure generally relates to a pre-tightening disc spring, comprising a disc-shaped body which is integrally formed, the disc-shaped body being formed with a central hole, the disc-shaped body having a first contact side and a second contact side which are opposite to each other in a thickness direction of the disc-shaped body, the disc-shaped body being a rotation solid formed by rotating a radial section about a central rotation axis by 360 degrees, the central rotation axis coinciding with a central axis of the central hole, the radial section having a first line segment and an opposing second line segment, the first contact side being defined by rotating the first line segment, the second contact side being defined by rotating the second line segment, a medium-diameter axis being defined to passing a mid-point of the second line segment and extending normally relative to the second line segment, the radial section being mirror-symmetrical relative to the medium-diameter axis, the medium-diameter axis being non-parallel to the central rotation axis, the first line segment being curve-shaped, the notch of the curve shape being oriented towards the mid-point of the second line segment, a point of intersection of the medium-diameter axis and the first line segment being a point such that a vertical distance measured from this point to a straight line segment connecting between both terminals of the second line segment is the greatest one among vertical distances measured from all points in the first line segment to the same straight line segment, wherein in a free state of the pre-tightening disc spring, the minimum thickness between the first and second contact sides of the disc-shaped body is greater than ¾ of a free height of the disc-shaped body and greater than 1/12 of a free outer diameter of the disc-shaped body.

摘要： Method for press-rolling a mainspring, from a wire comprising a pre-formed eye, utilising a roller press comprising a first support and guide means exerting a force on the wire in a first contact area located between a second and a third contact area comprised in a second and a third support and guide means, in order to wind, beyond the eye, an accumulation area with an opposite curvature to that of the eye, and wherein, as the wire advances, the position of the first contact area is gradually moved away from the second and third contact areas, to vary the press-rolling radius from a first minimum value to a second maximum value at a neck junction between the accumulation area and the eye.
