Abstract: A slotted waveguide antenna comprises a plurality of radiating waveguides (38-1, 38-2,...) having at least one radiating slot (40), a feed waveguide (36) for feeding to the radiating waveguides (38-1, 38-2,...), and coupling apertures arranged between the feed waveguide (36) and the radiating waveguides (38-1, 38-2,...) at a distance of an integer multiple of teh guide wavelength (λ g ) of the feed waveguide (36). The plurality of radiating waveguides (38-­1, 38-2,...) are disposed in parallel to form an array in a manner that the radiating slots (40) in the respective radiating waveguides (38-1, 38-2,...) are directed in the same direction. The feed waveguide (36) is on the same plane as the array formed by the radiating waveguides (38-­1, 38-2,...). The transverse width of each radiating waveguide is one half of the distance between the adjacent coupling apertures (46-1, 46-2,...). The coupling apertures (46-1, 46-2,...) provided on the feed waveguide (36) supply electromagnetic waves having the same amplitude and the same phase to each radiating waveguide (38-1, 38-­2,...). The feed waveguide (36) and the radiating waveguides (38-1, 38-2,...) are arranged integrally on the same plane so that the overall structure is planar. The structure of the antenna is simple, so that the antenna is manufactured easily and inexpensively.

Abstract: In a DC-DC converter of the quasi-resonant converter type, an inductive element (L'), which determines resonance, is provided as a part of the smoothing inductor (L) in the load circuit or as an additional inductive element which is magnetically coupled to the smoothing inductor (L). During energy transmission of the DC-DC converter, a part of the resonant current flows without delay to the output of the DC-DC converter, and into its capacitor (CG) on the output side. In consequence, the influence of the phase shift on the smoothing inductor is considerably reduced, as a result of which the dynamic characteristic of the DC-DC converter is improved. <IMAGE>

Abstract: The invention relates to a method of producing three-dimensional build-up parts by polymerisation of a photopolymerisable liquid system with the aid of high-energy radiation, in which method a band of the liquid system is continuously applied from a pouring device to the surface of a carrier liquid, which has a higher relative density than the photopolymerisable system and cannot be mixed with the latter. This band is polymerised by irradiation to form a two-dimensional polymer layer in band form, the liquid surface is subsequently raised and once again a band of the photopolymerisable system is applied and polymerised to form a further polymer layer, which unites with the previous layer. These steps are repeated until the three-dimensional component has been built up. The method steps of forming the polymer band and raising the liquid surface may be computer-controlled.

Abstract: A method and apparatus for determining the correct temperature of a heated coil (10) of sheet material and for using said measurement to control a heat treating furnace (12). The method includes providing a spot (14) of heat resistant material having a known and constant emissivity on an uneven edge of the coil (10), the material of the spot (14) remaining on peaks of the uneven edge. The constant emissivity of the spot is independent of that of the edge, which edge changes and is substantially less than the true temperature of the edge. The coil (10) is heated and the spot (14) emits infrared energy in an amount that is substantially representative of the correct temperature of the coil (10). This infrared energy is sensed by an infrared detector (30) aimed at the spot (14), the output of the energy being indicative of the true temperature of the edge and of the coil (10) mass after it attains the temperature of the edge.
