Abstract: The method is for making a shoe, in particular a ski boot for cross-county skiing. In the case of such a shoe, the upper comprises two or more layers, of which at least two are joined to each other under the effect of pressure. The pressure is exerted by a deformable air-tight surround, which bears firmly against the upper by at least partially removing the air present between the surround and the upper. The invention provides that the upper (2), joined to an outsole, is drawn onto the last (1) and introduced into a deformable surround (8), which can be closed up and pressed against the upper (2) and the last (1) by reducing the pressure prevailing in it, so that the deformable surround (8) encloses on all sides the upper (2) drawn onto the last (1). As a result, the contact of the layers (5, 6) forming the upper (2) is ensured and a good result of the heat treatment is guaranteed. <IMAGE>

Abstract: Method of compatibly increasing the resolution in a color television system employing offset modulation at the transmitter and offset demodulation at the receiver and transmitting a reference signal during the vertical blanking interval. The reference signal includes two components of which the first component contains phase information regarding the spectral addition at the receiver and the second component contains information regarding the offset modulation phase. Thus offset demodulation is realized at the receiver while retaining compatibility with existing television standards.

Abstract: As used in a digital television receiver, the invention is associated with a first phase locked loop which develops a sampling clock signal that is locked to the horizontal line synchronizing signal components of a composite video signal. A second digital phase locked loop is clocked by the sampling clock signal and develops a digital signal that is phase locked to the color burst signal. This digital signal is used as a regenerated color subcarrier signal to synchronously demodulate the chrominance components of the composite video signals into I and Q color difference signals. To compensate for frequency instability in the regenerated subcarrier signal caused by frequency instabilities in the line-locked clock signal, a third digital phase locked loop (300) develops an output signal which is phase locked to a reference signal generated by a crystal controlled oscillator (310). Control signals (Cʹ) from the third phase locked loop are applied (328) to the second phase locked loop to substantially compensate for frequency instabilities in the regenerated subcarrier signal that are induced by the clock signals.

Abstract: In a CVD method, a wafer (3) is retained on a wafer holder (2) in a reaction tank or chamber (1) to be put under reduced pressure. At least one through hole is made in an insulating film formed on a substrate of the wafer (3). A gas containing at least a metallic element is introduced into the reaction chamber (1) under reduced pressure so that a first metallic film of the metal element is formed on the substrate in the through hole of the insulating film of the wafer (3). This gas and a reduction gas are then introduced into the reaction chamber (1) under reduced pressure through inlets (4ª, 4 b ) and radiation from a heating lamp (8) is directed on to the wafer (3) so that a temperature difference arises between the insulating film and the first metallic film, as a result of differences of absorption rates of the radiation between the insulating film, the substrate and the first metallic film. A chemical reaction is effected only on the first metallic film, and a second metallic film of the metal element is formed on the first metallic film. 
     The metallic element containing gas may be introduced in a sheet-­like manner substantially parallel to the surface of the wafer (3) by shaping the inlets (4ª, 4 b ) so that their width is much less than their length. An inert gas or a gas containing mainly inert gas is introduced through a perforated plate (6ª) towards the surface of the wafer (3) so that the reaction gases maintain laminar flow (R, Rʹ). The metallic element containing gas and a reduction gas such as hydrogen are then introduced in a sheet-like manner substantially parallel to the surface of the wafer (3) into the reaction chamber (1) under reduced pressure, the at least substantially inert gas being introduced towards the surface of the wafer (3). The wafer (3) is heated so that a second metallic film of the metal element is formed on the first metallic film.

Abstract: The invention is based on a process for making shaped belts, in particular toothed belts, from rubber or the like. In order to make such belts cost-effectively and to be able, if required, to change the shaping with little effort, it is proposed by the invention to deform in the shape of an arc a sheet of rubber having a flat upper side and a flat lower side and with the reinforcing inserts already embedded, and, in the tensioned state, to shape the convex surface by means of transversely running cuts. In the case of longitudinally running, mutually parallel reinforcing inserts, the shaping is followed by making longitudinal cuts, which are to be carried out parallel to the reinforcing inserts in order to divide into a plurality of belts. <IMAGE>
