Inventor: KRECKL HERBERT
IPC: H01R13/713
Filed: 1990-11-12
Abstract: A heating plate for a domestic electric cooker has, in a known manner, a protector with a connecting block to which the leads coming from the domestic cooker controller are connected. Until now, the leads led from the connecting block to a further connecting block, which is likewise connected to the heating plate, from which the leads coming from the protector are connected to the heating resistors of the heating plate. It is intended to simplify the complete arrangement in such a manner that all the cable connections of a cable harness can be connected to a common plug on it. In this arrangement, it is also intended that the additional connecting block for making contact with the heating resistors for the heating plate be omitted. This object is achieved in accordance with the innovation in that all the connecting tabs (7) for plugging on a common plug of a cable harness are provided on the connecting block (6) for the protector. This solution according to the innovation allows the making of the contact with the heating plates to be significantly speeded up, it also being possible to use untrained personnel. The additional connecting block can be omitted. <IMAGE>

Abstract: Anode-side short-circuits in thyristors can be manufactured with little expense by first producing a p-doped layer on the anode side. After an oxide masking and oxide structuring, recesses (7) are then manufactured which extend down to the anode-side base zone (1) of the thyristor and in which the short-circuit regions are then produced. After removing the oxide, the anode electrode which makes contact to the p-doped layer and the short-circuit regions is deposited. Alternatively, the short-circuit regions may also first be produced through the openings of a structured oxide. After removing the oxide, p-doping is then carried out over the entire surface, the doping being lower than that of the short-circuit regions. The anode electrode is then deposited.

Abstract: A grinding wheel (12) for grinding a workpiece (6) can alternatively be fed in radially towards this workpiece (6) or a dressing roll (19). Between two dressing operations, that is, during the machining of the workpiece (6), the dressing roll (19) is conditioned with a conditioning wheel (50). The dressing roll (19) has linear contact with the grinding wheel (12) but point-like contact with the conditioning wheel (50). The relative radial and axial movements between conditioning wheel (50) and dressing roll (19) are synchronised by program control during the conditioning. The grains of the dressing roll (19) are harder than the abrasive grains of the grinding wheel (12) but softer than the grains of the conditioning wheel (50). Short dressing times as well as great flexibility are thus achieved so that the process is also suitable for small-batch production.
