Abstract: A receiver side of a two-wire type remote control system accurately determines the polarity of data. The reception buffer inverts an input from one of the data and electric communication lines, and adds the inverted input to an input of the other line. Then, when the result of the addition is 0 or close to 0, the reception switches buffer logic data to be output to indicate the inversion of the level of the equilibrium pulse-like power received from the communication lines. The polarity identifying portion identifies the polarity when the logical data sent from the reception buffer is maintained at a logic level for a predetermined period of time. The polarity identifying portion sends pulse group data to the data processing portion in accordance with the identified polarity.

Abstract: The invention relates to so-called scanning tips of probes necessary for scanning a measured object, in particular in scanning force microscopes and other scanning microscopes, so-called scanning probe microscopes. The possible resolution of such microscopes depends primarily on the fineness of the tip, i.e. its curvature or radius being as small as possible. According to the invention, a photostructurable material, e.g. a photosensitive resists, serves as the material for the scanning tip which is exposed via a mask and is subsequently developed/hardened in a manner known per se. The unexposed parts of the photosensitive resist are removed as usual. By the shape of the exposure mask, the preferably directed exposure of the photosensitive resist, and the subsequent hardening, a tip is formed preferably laterally on or at a carrier, usually made from a different material, which is provided with a very small radius, thus very well suitable for scanning probe microscopy and similar applications.

Abstract: A lightweight support for a bumper is formed by an extruded profile with a plurality of chambers. In order to provide a profile which, along with an extremely low weight, meets all the static requirements, is easy to bend and is suited to the properties of a light-metal alloy, the profile (1) comprises four walls (2, 3, 5, 6), which preferably form an isosceles trapezoid, and two webs (7, 8), which are arranged in the interior of the profile, parallel to the side walls (5, 6) and likewise symmetrically. The side walls (5, 6) of the support (1) have stiffening ribs (25) which are produced in the same operation as the support (1) is bent. A description is given of the associated process.

Abstract: A plasma process and equipment for eliminating toxic or hazardous organic compounds from different materials, particularly petroleum and oil contaminated soils. The process and equipment can also be used to remove the hydrocarbons contained in the sludge formed at the bottom of petroleum storage tanks. The process utilizes a plasma system for providing the necessary energy to the contaminated soil or sludge for the hydrocarbons to volatilize, keeping the temperature inside the reactor between 400 and 900° C. The volatilized compounds after leaving the reactor are collected in condensers, where the hydrocarbons can be recovered, in the form of a liquid hydrocarbon (oil). The contaminated material is continuously fed into the reactor from one end, while the clean material is removed from the other end of the reactor. The atmosphere inside the reactor is maintained neutral or reducing in order to prevent the oxidation of the hydrocarbons. Minimum amounts of off gases are generated in the process.
