    摘要： A current mirror includes first through eighteenth transistors. The load paths of the first and second transistors are in series for carrying an input current to a first supply potential. The control terminals of the first through eighth transistors receive the input current. The load paths of the fourth, third, ninth and tenth transistors are in series between the first and a second supply potential. The third and ninth transistors form a tap being connected to the control terminals of the ninth, tenth, eleventh, twelfth and thirteenth transistors. The load paths of the fifth, sixth, eleventh and fourteenth transistors are in series between the first and second supply potentials. The sixth and eleventh transistors form a tap being connected to the control terminals of the fourteenth through sixteenth transistors. The load paths of the seventeenth, seventh, twelfth and fifteenth transistors are in series between the first and second supply potentials. The seventh and twelfth transistors form a tap being connected to the control terminals of the seventeenth and eighteenth transistors. The load paths of the eighteenth and eighth transistors are in series for tapping a first output current proportional to the input current from the first supply potential. The load paths of the sixteenth and thirteenth transistors are in series for tapping a second output current equal to the first from the second supply potential. The ninth through sixteenth transistors are of one, and the seventeenth, eighteenth and first through eighth transistors being of the other, conduction type.

    摘要： The invention relates to a process for the continuous treatment of silicon in which a slag in a pivotable low-shaft furnace (1) with a discharge pipe (4) reaching the bottom of the furnace tank is taken to a temperature of 1450.degree. to 1800.degree. C. and this slag is used to melt solid silicon and/or liquid silicon is continuously refined and the liquid refined silicon is then sprayed with compressed air or nitrogen (7) and continuously conveyed into a transport crucible (11) by being poured into a stream of water (9) in the channel (8) via a dewatering filter (10) and thus obtained in granular form. The invention also relates to devices for implementing the process.

    摘要： The invention shows knock-out instruments for the shanks of hipjoint prostheses, the said instrument consisting of a shank (1) with a coupling-part for a sliding hammer (not shown) as well as of an extension-piece (3) which may be applied in the knock-out direction. The extension-piece (3) is connected rigidly to the shank and stands away from it like a foot at an angle .alpha. of between 20.degree. and 60.degree.. The extension-piece exhibits a recess (8) which may be slid from one side over the neck of a hipjoint prosthesis and encircles it over an angle of up to 180.degree., the width inside the recess measured across the 180.degree. being greater by a clearance than the smallest diameter of the neck of the prosthesis, measured in the same direction. The recess is further formed so that it engages the prosthesis in the area of the neck at three points arranged to lie in a plane substantially parallel to the axis of the shank so that, when the line of action of the sliding hammer is offset relative to the shank axis, a moment generated thereby is opposed by a moment generated between the extension piece and the neck at these three points.
