Patent EP-0219243-A2 (EP)
Inventor: BHAKTA JAYENDRA
IPC: H01L21/225
Filed: 1986-09-23
Abstract: A process for forming a buried layer 22 comprises the steps of covering a wafer (10) with a silicon dioxide layer (18). Dopants are introduced into the silicon dioxide layer (18) via an ion implantation process. Thereafter, a second silicon dioxide layer (20) is grown on the first silicon dioxide layer (18) and the wafer (10) is then subjected to a heating process which serves to both anneal the silicon wafer and drive dopants implanted into the first silicon dioxide layer (18) into the silicon wafer. In this way, crystal lattice damage which normally accompanies ion implantation is avoided. The second silicon dioxide layer (20) prevents out diffusion of the implanted ions from the first silicon dioxide layer (18) into the atmosphere. The first and second silicon dioxide layers (18,20) are then removed and an epitaxial layer (24) is formed on the wafer (10). A base region (48) and emitter region (46) are then formed in the epitaxial layer (24).

Abstract: In order to achieve a high efficiency of the commutating poles (17), and to relieve the armature feedback effect, as well as to prevent demagnetisation of the magnet segments (1), a two-piece commutating pole compensation winding is proposed for each commutating pole which consists of the halves (18a and 18b) of the commutating pole compensation winding, which halves are arranged in each case with one winding side in slots (22) in the region of the main pole fields in the magnetic return part, the other winding side of the halves (18a and 18b) of the commutating pole compensation winding being arranged jointly in a slot (21) in the pole centre of the commutating poles (17). Suitable means of attachment are provided in the intermediate spaces (23) for mechanical mounting of the magnet segments (1), and in this case the commutating poles (17) are used as a support. To prevent demagnetisation of the magnet segments and to control the speed, it is further proposed that the magnet segments be arranged on the pole cores of a field winding. <IMAGE>

Abstract: The present invention relates to modified emulsifiers particularly but not exclusively for foods and beverages. 
     In accordance with the present invention there is provided an emulsifier having at least one ionisable chemical group therein, such that in an aqueous solution the emulsifier carries a charge of one sign, characterised in that the emulsifier has been modified by the binding thereto of a polysaccharide stabiliser having at least one ionisable chemical group therein, such that in an aqueous solution the stabiliser carries a charge of the opposite sign. 
     It has been found that the method of formation of the modified stabiliser can be critical since some interactions appear not to extend across lipid/water interfaces. 
     Furthermore the presence of salts and acid components can adversely affect the formation of the modified stabilisers. Thus these components should generally be added later. 
     The modified emulsifiers is useful as, or in, foods and beverages, and also industrially for example in drilling mud compositions.

Abstract: A protective covering for an annular object, such as a caster wheel, comprises a continuous band (12) of heat-shrinkable plastic material defining spaced marginal edges, the band being proportioned to be closely received over and about the object in overlapping relation for heat-shrinking thereagainst, whereby the band is tensioned against the object. The band is formed to provide what becomes a tear or release strip (19) that functions to sever the band, when removal of the covering is desired, from one side edge (22) of the band to the other. When removal of the covering from the object is desired, the tear strip (19) is created by pulling or peeling a designated portion of the covering laterally outwardly of the object, and from one side edge (22) of the covering to the other side edge of same, to sever the protective covering, which covering then springs free of the object. A method is disclosed for application of the protective covering over the wheel tread.

Abstract: The invention relates to a press for drawing sheet components, in which the hold-down force during the drawing operation is applied to the hold down of the tool by a drawing apparatus of the forming machine. In order to be able to set the hold-down force individually, preferably zone by zone, with accuracy of reproduction and low inertia and hold it at the preset value, the drawing apparatus (es) is (are) designed in such a way that a hydraulically controlled die cushion is used during the drawing operation. A hydraulic hold-down force control is provided for the (each) die cushion of a press. Via a pressure or force sensor assigned to each die cushion, it is possible to measure the associated hold-down force. Via a forward path formed by a controller and a throttle valve under electrohydraulic pilot control, the force-determining pressure space of the die cushion can in each case be adjusted individually to the required pressure. This forward path operates with a low inertia and substantially without hysteresis, allowing the desired value for the hold-down force to be changed in accordance with a recurring functional sequence, even during a pressing cycle. <IMAGE>
