Abstract: The invention relates to a device for moving the lasting blades on a shoe lasting machine for pushing over the lasting edge, which is held by pulling-over grippers, of the shoe shaft, which is drawn onto a last, onto the insole which is arranged on the last bottom, in which the lasting blades, which are articulated on a shearing head, are moved by means of the shearing head essentially in the longitudinal direction of the last and the external ends of the lasting blades are pivoted in essentially perpendicularly to the longitudinal direction of the last, and, after the last inward movement of the external ends of the lasting blades, the lasting blades are moved only in the longitudinal direction of the last. In order to be able to change the latter movement in terms of time and according to its length, it is essentially envisaged with the invention that the shearing head is assigned, in addition to the main drive which acts in the longitudinal direction of the last, a supplementary drive which can be controlled independently of the main drive and acts in the longitudinal direction of the last. <IMAGE>

Abstract: A semiconductor substrate ( 1 ) has on its major sur­face a N⁻ drain region (2), within which a P base region (14) is selectively formed. In the P base region (14) is formed a P⁺ base region (15) which has a higher impurity concentration than that of the P base region (14). A source region ( 16 ) is selectively formed across and within the P base region (14) and P⁺ base region (15). The source region ( 16 ) has a lightly doped N source region (16a) and a heavily doped N⁺ source region (16b). The N⁺ source region (16b) is entirely formed within the P⁺ base region (14) so as not to form an N⁺P junction which is high in emitter injection efficiency and thereby to make a parasitic transistor hard to operate. Furthermore, the N source region (16a) is formed smaller in depth than the P⁺ source region (16b) so as to decrease the base spreading resistance of the parasitic transistor and thereby to make the parasitic transistor hard to operate. A gate electrode (9) is formed over a channel region (7), which is a portion of the P base region (14) that is sandwiched between the N⁻ drain region (2) and the N source region (16a) and exposed to the major surface of the substrate ( 1 ), with a gate insulating layer (8) interposed therebetween.

Abstract: In a control arrangement for the power output stage of a variable-frequency transmitter which measures the amplitudes of the waves transmitted and returning on the antenna feedline and evaluates these for deriving a control signal, a signal component is split off from the transmitter signal in front of the output stage and combined in a single-sideband generator with a constant-frequency low-frequency signal to form a single-sideband signal. The signal voltages coupled out of the antenna feedline by means of a directional coupler arrangement and proportional to the transmitted and returning waves are connected using the single-sideband signal in mixers, and from the mixer output signals components originating from external signals are suppressed by low-pass filtering and from the components to be allocated to the transmitted signal via the transmitted and returning signals are obtained for the control signal generator after amplification and rectification. <IMAGE>
