摘要:
A motor-driven hand circular saw, has a base plate, a motor, a drive housing surrounding the motor, a saw blade provided with saw teeth and being in operative connection with the motor, a saw blade housing accommodating the saw blade, an upwardly movable saw shaft having the saw blade, a hinge arranged so that the drive housing together with saw blade is movable upwardly and downwardly normal to the saw shaft with respect to the base plate for cutting depth adjustment. The saw blade is movable in and out. A turning hinge having a turning axis extends in a feed direction so that the saw blade housing is connected through the turning hinge with the base plate, and there is at least one upper and lower handle with respect to the base plate. The saw blade housing with the saw blade is located at the left and the drive housing is located at the right as considered in the feed direction. The hinge for cutting depth adjustment is arranged at the front side of the base plate as considered in the feed direction. The upper handle is formed as a pistol-like handle having a free end extending parallel to the feed direction and toward the base plate downwardly.

A flat cable having at least two conductor planes, in which a number of electrical conductors running in the longitudinal direction of the cable are arranged, in which the electrical conductors in the flat cable thickness direction and/or in the flat cable width direction are kept at a defined distance from each other by means of a central insulation layer of predetermined thickness acting as a spacer insulator and are electrically insulated and positioned relative to each other and to the flat cable exterior by means of an outer insulation layer.

A transversally electrically excited gas discharge laser for generating light pulses with a high pulse repetition rate. The gas discharge laser has components include a gas-tight discharge tube with opposed wall passages and front ends. The discharge tube includes ceramic material with laser gas sealed therein. The components also include partial metal layers disposed on the discharge tube. Decoupling and holding elements including support trays are disposed in the wall passages, with the support trays being adhered with solder to the discharge tube via the partial metal layers. The components also include a pair of electrodes extending axially and disposed in the decoupling and holding elements so as to form a gas discharge path. The components also include a pair of rod-shaped electrodes disposed in the discharge tube that are substantially parallel to the main electrodes and operable to control the starting conditions of gas discharge. The electrical excitation circuit includes a switch to generate a high-current discharge from an energy storage device. Support rings are joined to the front ends of the discharge tube and a pair of optical resonator mirrors are welded into the support rings. At least some of the components are usable with an ultrahigh vacuum and heatable to above a second water boundary. The support trays and the support rings are deformable so as to enable fine adjustment of the main electrodes and of the resonator mirrors.

摘要:
A high-power switching module for directly feeding pulse energy to a load includes a plurality of series-connected switching stages. Each switching stage includes a semiconductor switch; a snubber capacitor and a synchronizing resistor; and a control network configured to act on the semiconductor switch and to be supplied with auxiliary power and switching pulses from a pulse driver so as to influence a switching of the semiconductor switch. The control network includes at least one control resistor, a control diode, an auxiliary diode, an auxiliary capacitor configured to decouple and store the auxiliary power so as to maintain an offset voltage at the semiconductor switch, and an adjustable time-delay element series connected to the control diode and connected in parallel with the control resistor. The adjustable time-delay element is configured to variably set the offset voltage for the semiconductor switch that determines the switching of the semiconductor switch.
