摘要:
A hand-operated jigsaw is disclosed. The reciprocating drive mechanism has a reciprocating body which can be put into a reciprocating motion along an axis via an eccentric of an eccentric wheel that can be set in motion by the motor. The eccentric wheel is arranged on a pivot bearing axis. The reciprocating drive mechanism has an additional mass with a mass center of gravity to minimize vibrations. The additional mass is arranged in a rotationally fixed manner with the eccentric wheel on the pivot bearing axis. An eccentric axis of the eccentric lies on a first radial of the pivot bearing axis, which is offset from a second radial in the operating direction of rotation of the eccentric wheel at an angle of between 190° and 270°, which second radial lies between the mass center of gravity of the additional mass and the pivot bearing axis.

A hand machine tool includes a tool retainer that retains a tool, a motor that drives the tool retainer in a rotary motion, and a torque-controlled sliding clutch that is connected in a drivetrain between the motor and the tool retainer. The sliding clutch includes a first clutch disk, a second clutch disk, a spring and a controlling unit which can be activated manually. The second clutch disk is arranged displaceably alongside an axis limited by a stop in the direction toward the first clutch disk. Force is applied to the second clutch disk by the spring alongside the axis in the direction toward the first clutch disk. The manually activated controlling unit variably sets an axial distance between the first clutch disk and the stop, with which an engagement depth of the first clutch disk with the second clutch disk can be defined.

A method, apparatus, and computer program for modeling mathematically an effect of a plurality of factors on signal distortion caused by a non-linear amplifier are provided. First, there is computed a global model which incorporates a combined effect of the plurality of factors on signal distortion caused by the non-linear amplifier. Before applying the pre-distorted transmission signal to the non-linear amplifier, a transmission signal is pre-distorted with coefficients derived from the global model thus compensating for the signal distortion caused by the non-linear amplifier.

A semiconductor component and a method for its production in semiconductor chip size, can have a semiconductor chip, which has external contacts of the semiconductor component that are arranged in the manner of a flip-chip on its active upper side. The semiconductor chip can be encapsulated by a plastic compound at least on its rear side and its side edges. The outer contacts, which can be arranged on external contact connecting areas, can project from the active upper side.
