20090221112Method for Metallizing Semiconductor Elements and Use Thereof - The present invention relates to a method for metallizing semiconductor components in which aluminium is used. In particular in the case of products in which the process costs play a big part, such as e.g. solar cells based on silicon, a cost advantage can be achieved with the invention. In addition, the present invention relates to the use of the method, for example in the production of solar cells.09-03-2009
20100301456METHOD FOR APPLYING A STRUCTURE TO A SEMICONDUCTOR ELEMENT - A method for applying a predetermined structure of a structural material to a semiconductor element. The method includes the following steps: A) partially covering a surface of the semiconductor element with a masking layer, B) applying a film of a structural material to the masking layer and to the surface of the semiconductor element in the zones that are devoid of the masking layer and C) removing the masking layer together with the structural material present on the masking layer. The method according to the invention provides that between process steps B and C, the film of structural material is partially removed in a process step B2.12-02-2010

20110108640SHOWER HEAD FOR A SANITARY SHOWER FITTING - A shower head for a hand-held shower attachment, an overhead shower attachment or a side shower attachment contains, in its shower-head housing, a vortex chamber which is of funnel shape with the side wall curved. The funnel begins, at the location of the largest diameter, in a radial plane and then decreases in diameter along a curved contour to an exit, where the walls of the funnel run in the axial direction. At the location of the largest diameter of the vortex chamber, upstream of this tapering region, the water is let in tangentially in the circumferential direction and in the axial direction. The vortex which is generated by virtue of the water being let in tangentially accelerates its speed of rotation in the direction of the spray disc. Arranged at the end of the tapering region is a jet-outlet chamber which is very flat, but is of large diameter in relation to the vortex chamber. The vortex travels into this jet-outlet chamber, and therefore, even in the outer region, water jets exit with a massage action out of the jet-outlet openings which are present there.05-12-2011

20080210509Method for Determining A Driving Torque Correction Factor for Compensating Cooperating Driving Torques of Different Drive Devices - A method and device for determining a driving torque correction factor for compensating the driving torques of a drive unit including a first drive device and a second drive device, both of which act with their driving torque on a common drive shaft. The method includes specifying and setting a desired driving torque for one of the two drive devices, adjusting a brake torque for the other of the two drive devices to a brake torque value, which is equivalent to the value of the actual driving torque (that occurs on the basis of the desired driving torque) of one of the two drive devices, and determining the correction value as a function of the specified desired driving torque of the one drive device and as a function of the brake torque value of the other drive device, the brake torque value being adjusted at the time of the compensation of the torques.09-04-2008
