摘要:
A method of producing a crystalline semiconductor material includes feeding particles of the semiconductor material and/or a precursor compound of the semiconductor material into a gas flow, wherein the gas flow has a sufficiently high temperature to convert the particles of the semiconductor material from a solid into a liquid and/or gaseous state and/or to thermally decompose the precursor compound, condensing out and/or separating the liquid semiconductor material from the gas flow, and converting the liquid semiconductor material to a solid state with formation of mono- or polycrystalline crystal properties.
摘要:
A method of producing a monocrystalline semiconductor material includes providing a starting material composed of the semiconductor material, transferring the starting material into a heating zone in which a melt composed of the semiconductor material is fed with the starting material, and lowering the melt from the heating zone and/or raising the heating zone such that, at a lower end portion of the melt, a solidification front forms along which the semiconductor material crystallizes in a desired structure, wherein the starting material composed of the semiconductor material is provided in liquid form and fed into the melt in liquid form.

In order to treat solar cells in an electroplating device, they can be inserted into a grid-like or tray-like picking-up device. They are thus mechanically held and electrical contact is made with them via contacts. Instead of individual solar cells, the picking-up devices are moved with a large number of inserted solar cells through the electroplating device for treatment. Electrical contact with the solar cells is in this case made via the contacts and the frame limbs on a projecting angle section together with edge strips of the pick-up. Contact rollers rest on the edge strips and are connected to an electrical power source.

A method and apparatus are provided for automatically trimming a plurality of printed products in a trimming apparatus having at least one trimming station including at least one blade positioned on a moveable yoke. The plurality of printed products are supplied successively through a feeding conveyor to the trimming station. Each of the plurality of printed products is transported within the trimming station via a trimming transport device to a predetermined position for trimming. The phase position of the feeding conveyor is adjusted relative to the moveable yoke for each of the plurality of printed products according to the format width of the printed product extending in a conveying direction.
摘要:
The present invention relates to an inkjet ink comprising: a) colorant; b) a polymeric binder having an acid number below 200 selected from the group consisting of a styrene-acrylic polymeric binder, an acrylic polymeric binder, an anionic polyurethane binder and combinations thereof; c) water dispersible surfactant; and d) a solvent which does not dissolve an acidified form of the binder, the solvent having a vapor pressure less than 0.1 mm at 25° C. The invention further relates to methods of making using the ink, printing systems and ink sets which use this ink.
摘要:
An installation apparatus for an expansible anchor has a clamping piston guided in an expansion piston, both of which are perated by compressed air. The clamping piston has a clamping cone for a collet chuck. It slides on the collet chuck, which is fixed in the housing, and clamps a shank of the expansible anchor. The expansion piston displaces an expansible sleeve on the shank of the expansible anchor by an expansion plate which is screwed to the expansion piston and has a hole at its center, through which the shank of the expansible anchor projects into the collet chuck. The apparatus has the advantage of a closed force path as the expansible anchor is expanded, so that the anchor does not need to be steadied by a work-piece. In this manner, slabs or tiles having a small residual wall thickness at the bottom of a drilled hole are prevented from being damaged as the expansible anchor is installed.
