Abstract: In order to be able to investigate non-conductive specimens in an electron beam apparatus in a charge-neutral manner, a charge applied by the scanning electron beam is neutralized with the assistance of charge carriers present in a metal plasma. The plasma is generated by a gas discharge between two electrodes positioned with the vacuum specimen chamber of the electron beam apparatus. One of these electrodes has a layered structure (e.g. metal-insulator-metal) that facilitates the ignition of the gas discharge by means of a high-voltage pulse.

The base assembly provides an easily erected column structure usable in a variety situations where a temporary structure can be erected near to a parked vehicle, such as signs, lights, sheds, tents or awnings. The base assembly provides a sturdy and stable column base erectable on hard surfaces, eliminating the need for staking.

Abstract: The invention is directed to a method wherein pressure is exerted onto a semiconductor surface by a chemically inert and non-solid medium. An opposite pressure is prevented from building up in an intermediate layer, for example, with the assistance of a seal. A connection between the semiconductor and the substrate occurs by pressure sintering or by diffusion welding. A contact between an active, inside region of the semiconductor and a plunger can be avoided since the plunger has a raised and annular outside region for sealing, and the actual pressing power is effected by the pressure medium via a bore situated in the plunger. This raised edge for sealing can also be situated on the semiconductor instead of being situated on the plunger. When a semiconductor component is extrusion-coated with a plastic melt, then this plastic melt itself can serve as a pressure medium.

Abstract: For single-cylinder evaluation of an internal combustion engine, the respective angular velocity is measured--for respectively defined crank angle positions--at at least one component part of the internal combustion engine, the respective overall moment of inertia is calculated from the design data of the internal combustion engine and, while operating the overall moment of inertia with the angular velocity, the respective overall energy of the internal combustion engine is calculated. A single-cylinder evaluation can then be implemented from the comparison of these overall energies in cylinder-associated crank angle ranges.

Abstract: A liquid crystal display unit is provided wherein address lines for two mutually adjacent odd and even rows of pixels arrayed in a matrix are in common, and two vertical pixels on each column can be displayed simultaneously to enable display of an image corresponding to one frame. Capacitor forming electrode wires are supplied with a fixed potential are disposed between omitted rows of address lines eliminated due to the common use thereof, whereby the storage capacitors are of a sufficiently high value, even with a high resolution display, to enhance the image quality of the liquid crystal display unit. Since a fixed potential is applied to the capacitor forming electrode wire which forms the storage capacitor, the capacitor does not apply a load to the address line and thereby consistently insures a fast operation. As a result, improvements can be achieved relating to large image area and high resolution.
