Abstract: The invention proposes a switchable tappet (1) of a valve train of an internal combustion engine, said tappet comprising a hollow cylindrical housing (3) comprising a bottom (2), an inner element (5) being guided for relative axial displacement in a bore (4) of the housing (3), an at least indirect support for a gas exchange valve extending on a cam-distal front end (6) of the inner element (5), two diametrically opposing pistons as coupling elements (8) being arranged in a radial bore (7) of the inner element (5), which coupling elements (8), for effecting coupling [full valve lift], can be displaced partly beyond a parting surface (9) between the housing (3) and the inner element (5) into an entraining surface (12) of the housing (3) by the force of a compression spring (10a) clamped between inner front ends (10) of the coupling elements (8), wherein the entraining surface (12) is an direct constituent of a separate annular member (13) that is fixed in a cam-distal region of the bore (4) of the housing (3), wherein only one compression spring as a lost motion spring means (16) extends in a cylindrical hollow space (15) formed between an underside (14) of the bottom (2) of the housing (3) and a cam-side flat front end (14a) of the inner element (5), and wherein the inner element (5) is substantially disk-shaped and the parting surface (9) between the housing (3) and the inner element (5) does not comprise any vertical stop means. The invention proposes a switchable tappet (1) of a valve train of an internal combustion engine, said tappet comprising a hollow cylindrical housing (3) comprising a bottom (2), an inner element (5) being guided for relative axial displacement in a bore (4) of the housing (3) ...more ...less

Abstract: A grinding and polishing machine, in particular for lenses, has at least one tool spindle and at least one workpiece. The tool spindle is constructed to hold a respective tool on the same axis at both ends and is mounted in a spindle housing which can be pivoted about a pivot axis arranged at right angles to the tool spindle in order to provide in each case one tool for machining engagement and also at various defined angle positions with respect to the workpiece spindle. A drive arranged on the pivot axis pivotably moves the tool spindle about the pivot axis for the desired machining engagement and rotates the tool about the pivot axis into the various angle positions with respect to the workpiece. A grinding and polishing machine, in particular for lenses, has at least one tool spindle and at least one workpiece.

Abstract: An instrument for surgical purposes, especially for coagulation, is proposed. This instrument has at least one arm (2), the tips (4) of the arms having electrical contact regions (6, 7), which can be electrically connected to a control unit (12), for touching a tissue (13) for the purpose of coagulation. The contact regions are formed from doped diamond to produce the electrical conductivity. An instrument for surgical purposes, especially for coagulation, is proposed.

Abstract: A vertical semiconductor transistor component is built up on a substrate by using a statistical mask. The vertical semiconductor transistor component has vertical pillar structures statistically distributed over the substrate. The vertical pillar structures are electrically connected on a base side thereof to a first common electrical contact. The vertical pillar structures include, along the vertical direction, layer zones of differing conductivity, and have insulation layers on their circumferential walls. An electrically conductive material is deposited between the pillar structures and forms a second electrical contact of the semiconductor transistor component. The pillar structures are electrically contacted to a third common electrical contact on their capping side.
