摘要： A transistor with a gate electrode structure is produced by providing a semiconductor body with a first surface, and with a first sacrificial layer extending in a vertical direction of the semiconductor body from the first surface. A first trench extending from the first surface into the semiconductor body is formed by removing the sacrificial layer in a section adjacent the first surface. A second trench is formed by isotropically etching the semiconductor body in the first trench. A third trench is formed below the second trench by removing at least a part of the first sacrificial layer below the second trench. A dielectric layer is formed which at least covers sidewalls of the third trench and which only covers sidewalls of the second trench. A gate electrode is formed on the dielectric layer in the second trench. The gate electrode and dielectric layer in the second trench form the gate electrode structure.

摘要： The invention relates to a switching transistor presenting reduced switching losses. In the switching transistor, output capacitance is very high when drain/source voltages are low. As the drain/source voltage increases, the capacitance falls to such low values that the energy stored in the transistor becomes very low.

摘要： In a method for forming a channel zone in field-effect transistors, a polysilicon layer is patterned above the channel zone to be formed. The polysilicon layer serves as a mask substrate for the subsequent doping of the channel zone. The expedient patterning of the polysilicon layer with holes in a gate region and pillars in a source region enables the channel zone to be doped more lightly. In another embodiment, the novel method is used for a channel width shading of a PMOS transistor cell.

摘要： An abrasive coating is formed on the tip of a component of a drive unit for abrading an abradable coating during a stripping operation by thermal spraying a ceramic layer on the component, the ceramic layer being profiled and providing a succession of abrading edges and intermediate spaces between the abrading edges to take up and remove abraded material. The abrading edges can be formed as deposits of ceramic material on the component or, as a ceramic layer applied on a profiled surface etched on the component.

摘要： A mortar mixing machine has a frame and a hopper supported by the frame for containing dry mortar. The hopper has an outlet with an outlet opening. A first conveying and mixing tube, connected in a working position thereof to the outlet so as to extend horizontally, has at least one water inlet and is designed for mixing the dry mortar fed into the conveying and mixing tube from the hopper with water introduced via the at least one water inlet to prepare mixed moist mortar. The first conveying and mixing tube has a removal opening for the mixed moist mortar remote from the outlet. A second conveying and mixing tube is connected to the frame for directly receiving in a working position thereof the mixed moist mortar. The second conveying and mixing tube conveys the mixed moist mortar in a direction opposite to the conveying direction of the first conveying and mixing tube. The second conveying and mixing tube has a drive and is slidably retractable into a rest position together with the drive.

摘要： The treatment of a material web (2) ensues in a U-shaped shaft comprising two shaft limbs (3, 4) and a connecting area (5) between both the shaft limbs. The shaft is filled with a treatment liquid, the feed of fresh treatment liquid and also the circulation of treatment liquid ensuing beneath the surface of the liquor within the shaft limb. The effect is a particularly intensive charging of the material web, with extremely economic use of treatment liquid. Foaming of the treatment liquid is prevented, also in the case of heavy turbulence.

摘要： A fabric tenter device having a pivotally mounted roof which may carry a nozzle box is provided with a counterbalance assembly enabling the roof and box to be pivotally shifted from the tenter covering to an open position by manual lifting forces. The counterbalance assembly is comprised of a lever divided into two arms, the lever being pivotally mounted on a fulcrum fixed to the tenter housing. The lever includes a weight arm underlying the roof and a power arm to the opposite side of the fulcrum. A chain having one end fixed to the power arm has its other end attached to a spring mechanism carried by the weight arm, the chain being arranged over a guide roller or rollers in such manner that the spring is tensioned to its maximum extent when the roof is in the tenter covering position.
