Patent EP-0304046-A2 (EP)
Inventor: FUJIMURA SHUZO
IPC: H01L21/302
Filed: 1988-08-18
Abstract: In a downstream ashing apparatus for removing a used organic resist on a silicon semiconductor wafer, according to the present invention, water vapor is added into an oxygen plasma gas generated by a microwave power. The addition of the water vapor lowers an activation energy of the ashing reaction, and increases reactive species generated in the plasma, accordingly the ashing rate is increased even at as low as 150 °C of the wafer temperature. The addition of water vapor increases the ashing rate for a wide range of water content, such as from 5 to 80 %, allowing an easy control of the process. The lowered operating temperature prevents contamination of the semiconductor wafer. Nonuse of CF₄ protects the SiO₂ layer from being undesirably etched, resulting in prevention of deteriorating the semiconductor characteristics.

Abstract: In a method and a device for steering the rear wheels of motor vehicles as a function of a steering of the front wheels, an adjustment of the rear wheels is performed in accordance with the adjustment direction of the front wheels. In the event of an increase in the steering angle of the front wheels, the adjustment of the rear wheels is delayed, in the event of a reduction of the steering angle of the front wheels, it is performed without delay. As a result, a clear increase in the driving stability is obtained in comparison with motor vehicles in which only the front wheels are steered. <IMAGE>

Abstract: A machine is provided for glazing earthenware or porcelain, in particular plates or the like, in which a plurality of supporting arms are attached to a capstan, each of which arms has a workpiece holder. The workpiece holder advantageously has two glazing pots which can be rotated about their own axes by corresponding motors and are so mounted on the supporting arm in question that they are pivotable relative to the latter. Each supporting arm passes through a plurality of stations in the glazing machine. A centring station is provided in an intake zone, from which station the material, after centring and the application of a printed stamp, is passed to the glazing pots in the glazing station. In the glazing station, the material is dipped in a glazing bath, performing a rotary movement and a simultaneous pivoting movement, and is then brought into an approximately vertical position. Then the glazing pots are pivoted so that the glazed material is situated in an approximately horizontal position. In this substantially horizontal position, the material is stepped onwards to a transfer station from which the material is passed to a sponge belt, by which the foot of the material is freed of glaze. From the sponge belt, the material is then transferred, with the aid of suction cups, to a removal device in a removal zone, a conveyor belt advantageously being provided for this purpose.

Abstract: A system for controlling a boost pressure in an internal combustion engine equipped with a turbocharger. Engine operation is divided into three regions based on an engine speed with respect to an engine load. Throughout the regions, a target boost pressure is predetermined to be considerably lower than a level at which knock frequently occurs. In the region where the engine speed and load are relatively high, the target boost pressure is gradually raised until knock occurs. When knock occurs, the target boost pressure is fixed at a value slightly lower than the value at which knock has occurred and thereafter the boost pressure is controlled to the fixed target pressure.

Abstract: The present invention relates to a tube (1) made from cement and having a layer structure, the use of which is destined in particular to the hydraulic/building field. Said tube shows the characteristic that the usual asbestos fibres used in order to reinforce such kind of articles have been replaced by other fibres having similar functional features, for example of cellulose, at the inner surface (3) of said tube, which is destined to come into contact with the liquid conveyed inside the same tube. In correspondence of said inner surface, the usual Portland cement can be replaced by cement endowed with resistance to aggressive waters. The process for manufacturing such a tube consists in depositing at least two layers of reinforced cement mortar on a core, the outer diameter of which coincides with the inner diameter of the tube, and in such a way that such layers set simultaneously to the other layers, forming one enbloc cement structure, even if reiforced with different reinforcing materials. 
     The machine (10) for producing such a tube is equipped with a plurality of tanks (7,8) from which by means of conveyor belt (4) and of roll means (3,11,14,15) the cement mixture in the fluid state is alternatively drawn, which has to be deposited together with the fibres contained in it as layers on a core used in order to form the tube.
