Abstract:
An apparatus for setting the spacing of a free standing range relative to a floor includes a base component for contacting the floor, a threaded element, and a winding follower. The winding follower extends into the helical recess of the threaded element such that the winding follower travels progressively further along the helical recess of the threaded element. A blocking member engages the winding follower during travel of the winding follower along the helical recess of the threaded element to resist a disengagement movement.
Abstract:
A method for producing a silicon-on-insulator layer structure on a silicon surface with any desired geometry can locally produce the silicon-on-insulator structure. The method includes formation of mesopores in the silicon surface region, oxidation of the mesopore surface to form silicon oxide and rib regions from silicon in single-crystal form; and execution of a selective epitaxy process that that silicon grows on the uncovered rib regions, selectively with respect to the silicon oxide regions. Rib regions remain in place between adjacent mesopores, this step being ended as soon as a predetermined minimum silicon wall thickness of the rib regions is reached, the uncovering of the rib regions, which are arranged at the end remote from the semiconductor substrate between adjacent mesopores. The method can be used to fabricate a vertical transistor and a memory cell having a select transistor of this type.
Abstract:
In order to fabricate a semiconductor memory, a trench capacitor is arranged in a first trench. Beside the first trench, a first longitudinal trench and, parallel on the other side of the first trench, a second longitudinal trench are arranged in the substrate. A first spacer word line is arranged in the first longitudinal trench and a second spacer word line is arranged in the second longitudinal trench. There are arranged in the first trench connecting webs between the first spacer word line and the second spacer word line which have a thickness which, in the direction of the first spacer word line, is less than half the width of the first trench in the direction of the first spacer word line.
Abstract:
A rotary switch configuration for a household appliance includes a rotary knob seated in a cutout in an appliance panel and firmly connected to an actuating shaft so as to rotate with it but move axially, the actuating shaft transmitting the rotary movement of the rotary knob to a switching shaft of a switching unit mounted behind the appliance panel. Exact and wobble-free guidance of the rotary knob is achieved by the actuating shaft being rotatably mounted on the appliance panel by a bearing device.
Abstract:
In an integrated circuit with low threshold voltage differences of the transistors and a manufacturing process for such an integrated circuit, MOS transistors of different lengths but having threshold voltages that are substantially the same are made by avoiding dopant peaks at the channel edges by an angled nitrogen implantation, so that implantation paths at those edges are occupied by nitrogen atoms.
