A SiC wafer is produced from a single crystal SiC ingot. A focal point of a pulsed laser beam having a transmission wavelength to the ingot is set inside the ingot at a predetermined depth from a flat surface of the ingot, the predetermined depth corresponding to the thickness of the wafer to be produced. The pulsed laser beam is applied to the ingot to thereby form a separation layer for separating the wafer from the ingot. The wafer is separated from the ingot along the separation layer, and a flat surface is formed by grinding an upper surface of the ingot as a rough separation surface left after separating the wafer, thereby removing the roughness of the upper surface of the ingot to flatten the upper surface of the ingot.

Organometal-containing acrylate or methacrylate derivatives and photoresists comprising the polymers thereof. Unlike conventional matrix polymers of photoresist, the polymers induce a difference in silicon content between exposed regions and unexposed regions of photoresists by releasing their silicon-containing side chains with the aid of acid in a chemical amplification manner. The difference in silicon content causes the exposed regions to be etched at a different rate from that of the unexposed regions under oxygen plasma. Thus, the photoresist material makes it possible to use a microlithographic process comprising a dry development step which can advantageously prevent the deformation or collapse of patterns which is aggravated as their aspect ratio increases, as well as the photoresist is economically more favorable than a top surface imaging system to which silylation on its top surface or a multi-level resist system to which wet development on its top layer must be applied, because the microlithographic process is very simple and no solvent is released.

A process for producing a hollow monoblock shaft from a pipe, the pipe initially having a constant diameter and a constant wall thickness, and the monoblock component including at least one area of its length being of a smaller outside diameter and a greater wall thickness than the constant diameter and constant wall thickness of the pipe. The process can be carried out simply and economically by the following process steps:selecting a pipe with a wall thickness which corresponds to the smallest wall thickness of the finished component,partial heating of at least one area of the pipe,axial upsetting the heated area of the pipe andradial forging the heated area of the pipe.

A releasing device for a spring-loaded firing pin (1) or a spring-loaded firing-pin piece, in particular of a firearm, with at least one release trigger (2) that can be activated by hand, in particular, with at least one finger, and with a control body (3) acting on the firing pin (1) or the firing-pin piece. A transmission mechanism is arranged and / or acts between the release trigger (2) and the control body (1), and the transmission mechanism has a series of roller bodies (4) lying one on the other, advantageously balls and / or cylinders.

A cable transport device having a pivotably mounted cable transporter, a first drive means connected in a stationary manner to a base frame and intended for achieving an exactly defined pivot movement of the cable transporter around a pivot axis and a second drive means for synchronous driving of at least two cooperating pressure rollers. The second drive means with a drive axle for the pressure rollers is connected in a stationary manner to the base frame, and the drive axle of the second drive means coincides with the pivot axis for the cable transporter. In additional versions, the second drive means with a drive axle for the pressure rollers is also connected in a stationary manner to the base frame, and the rollers' axes of rotation are parallel to one another and parallel to a common pitch axis. In these versions, transmission of the drive movement to the toothed belt driving the pressure rollers is effected via a toothed belt which is tensioned symmetrically to the center of rotation of the pivot axis between a first intermediate shaft arranged on a base plate of the cable transporter and a second intermediate shaft fixed to the machine frame, the pitch axis of the cable transporter being identical to the axis of the first intermediate shaft. The cable transport device may be equipped with a guide sleeve that includes a grooved plate and a cover plate that may be replaced for adaptation to different cable diameters and for correction of the cable position.
