The device according to this invention comprises a casing in which turns a device designed to support and hold the wafer, the said device is fitted eccentrically with respect to its rotational pin (3) a support element 5-6 designed to hold the silicon wafer by its edges in a horizontal plane, the device assembly being mounted in stable balance with respect to the said pin.

1. A prelaminate which may be used instead of flexible single layers in the construction of rigid-flexible circuit boards, characterized in that it consists of a plate (1) of a non-flexible (rigid) material into which flexible, adhesive-coated plastic films (2) free from edge gaps and equal in thickness to the plate (1) are inserted in the regions where the subsequent circuit board is to be flexib...

1. A multilayer, locally rigid and locally flexible circuit board with through-connection holes consisting of several individual layers press-moulded with one another, characterized in that it is made up alternately of first single or double layers (2) and second single or double layers (3) of the same non-flexible (rigid) material into which flexible adhesive-coated plastic films (4) free from ed...

PURPOSE:To miniaturize and lighten the titled apparatus, and to shorten the processing time by a method wherein an exposure-beam generator is loaded on a carriage and constituted in a movable manner, a drive mechanism is divided into two sections centering around a wafer and the two sections are used as a fist moving means shifting a head and a second moving means transferring the heat at approxim...

A lead bushing (1) is connected by tightening to a socket-shaped seat part (9), and on its exterior has a peripheral ridge-shaped part (2) with a conical, downwardly inclined underside (3), and is inserted in an individual socket-shaped plastic part (5). On the inside of the plastic socket-shaped part is a part complementary to the conical, inclined underside of the lead bushing. A track (7) is pr...

The invention provides a process to manufacture fluoride-free potassium peroxydiphosphate on a commercial scale. The process comprises electrolyzing an alkaline anolyte containing potassium, phosphate, nitrate and hydroxyl ions at a platinum or noble metal anode. The catholyte is separated from the anolyte by a separating means permeable to at least one ion contained in the anolyte or catholyte.

The invention relates to a method for the preparation of a ruthenium promoted nickel and/or cobalt hydrogenation and/or dehydrogenation catalyst on a porous metal oxide support. Halogen is incorporated in the catalyst by adding a halide compound at any stage of the process in form of a non-ruthenium halide.

PURPOSE:To enable stirring with good energy efficiency by generating the annular rotating motion to raise the carrier deposits floating on the liquid in a digestion tank by a stirrer erected at the center of the tank and to lower the same in the peripheral edge part. CONSTITUTION:The anaerobic digestion tank 1 having an approximately circular horizontal section contains the deposits of the small g...

The housing and the shaft structure of a hydraulic motor are in a known manner provided with brake discs (3,4) which are actuated by a movable part (10) which is spring-loaded (16 or 17) on one side and subjected to a hydraulic pressure on the other side. The pressure chamber (8) is further defined by a part (9) stationarily secured on a shaft (2). The parts (9, 10) are reversible as can be seen f...
