Abstract: The invention relates to a process and a device for positioning and controlling a high-power energy source, in particular a laser, relative to a workpiece. In this case, the laser beam is positioned by means of an optical system and the surround field of the impingement site of the laser beam on the workpiece is observed during laser operation, whereupon the laser beam is controlled in accordance with the result of the observation. In order simply and exactly to configure the positioning and control of the laser beam, the direction of observation is selected according to the invention to be different to the direction of the laser beam, and in addition the impingement site of the laser beam on the workpiece itself is observed during laser operation. No additional illumination is required apart from the working laser. By optical filtering, there is generated in the observing plane an image of the impingement site relative to its surround field, from the contrast of which the information on positioning and controlling the laser is determined. <IMAGE>

Abstract: A wind deflector (5) for an open roof construction which is provided with a closure means adapted to open an aperture (2) in the fixed roof (1) of the vehicle, comprises an elongate body for arrangement in transverse direction near the front edge (4) of the roof aperture (2). The front side of the body has a backwardly and upwardly inclining portion (13) and a backwardly and downwardly inclining portion (14) connecting to the lower side of the first-mentioned portion. The transition between said portions is lying, in an operative position of the wind deflector (5), preferably level with, or slightly above or below, the level of the fixed roof (1) of the vehicle in front of the wind deflector. As a result a part of the air flow (10) arriving at the wind deflector (5) is forcingly deflected underneath said body and upwardly again behind the body when the vehicle is driven. A buffeting effect is counteracted in this manner.

Abstract: The disclosure is directed to an improved aerodynamic helmet. The helmet (10) has a continuous aerodynamic curvilinear front, side and top surfaces whereby the fluid flowing over and around the sides of the helmet flows in a substantially continuous flow direction (C) from the forward curved area aft of a straight area at the greatest width or largest transverse dimensions of the helmet after leaving the surface influence thereof. The continous transverse surface around the outer periphery of the helmet at or slightly aft of the greatest width may be provided with a fluid flow termination surface or trailing edge (14) causing the normal direction of the fluid flow (C) around the helmet to break loose from the surface of the helmet (10) and continue in substantially the same direction after passing the termination or trailing edge thereby preventing turbulence to the flow rather than allowing the fluid flow (C) to follow the surface and flow around a portion of the smaller dimention back surface of the helmet before separating therefrom which creates turbulence behind the helmet and unwanted lift thereto. The improved helmet lowers wind drag compared to conventional helmet by about 40%.

Inventor: BEASOM JAMES D
IPC: H01L21/331
Filed: 1990-12-20
Abstract: The occupation area and thickness of dielectrically isolated island-resident transistor structures, which employ a buried subcollector for providing low collector resistance at the bottom of the island, are reduced by tailoring the impurity concentration of a reduced thickness island region to provide a low resistance current path from an island location directly beneath the base region to the collector contact. The support substrate is biased at a voltage which is less than the collector voltage, so that the portion of the collector (island) directly beneath the emitter projection onto the base is depleted of carriers prior to the electric field at that location reaching BCVEO, so as not to effectively reduce BVCEO. Since the support substrate bias potential depletes some of the region of the island beneath the base region of carriers, the doping of the island can be increased compared to the case where the substrate is not biased, while maintaining the electric field at this location less than the BVCEO field.
