Granted: 1990-11-07
Abstract: An automatic system for performing sheet resistivity testing on surface layers of semiconductor wafers, including a wafer handling stage having a platform for carrying a semiconductor wafer, and an arrangement for mounting the platform for rotation about a central axis and for translation of the platform orthogonal to a major surface thereof. A platform drive translates the platform between a wafer test position and a wafer load position, and a stage drive rotates the platform to accurately located angular test positions. A probe handling arrangement includes a carriage for carrying a test probe parallel to the major surface of a wafer on the platform and a carriage drive translates the carriage between a parked position in which a test prove thereon is positioned adjacent and clear of the platform and accurately located test positions along a radius of the platform. The carriage carries a resistivity test probe which includes test probe element for contacting the surface of a semiconductor wafer. A light tight housing surrounds the platform and includes an access door therein facing the platform and positioned intermediate the wafer load position and the wafer test position of the platform. The access door translates under controlled motor drive between a closed position and an open position which permits the platform to translate between the wafer load and wafer test positions. Sensor arrangements cooperate with a safety inhibit circuit to preclude destructive movement of components when position conflict is sensed. All movements and measurements are under microcomputer control.

Patent EP-0250830-B1 (EP)
IPC: H01M50/541
Filed: 1987-05-20
Granted: 1992-02-12
Abstract: A device, configured as a double mold, for casting terminal bars (straps) and terminal poles onto the lugs of a completely assembled plate group for electric storage batteries ensures optimum attachment of all of the lugs (both polarities) to the molten bar lead if the heat exchange between the bar lead and the dipped volume of each negative or positive lug is identical. This requirement is met by causing the negative and positive casting molds, together with their contents, to form thermally equivalent sections or blocks, which are equalized if necessary, by changing the dimensions (thickness) of the mold's walls. When the lugs are made of lead or a lead alloy, such a double mold also makes it possible, during a subsequent two-stage cooling process, to first allow the terminal poles to solidify, simultaneously, and to then allow the terminal bars to solidify, simultaneously. If the negative plates of the cell group have copper grids and lugs (which may also be coated with lead or lead-tin alloys), the two-stage cooling process must be effected at different working rates for the two polarities.

Abstract: The measuring circuit comprises an integrator to which a signal representative of the current flowing through the primary winding of the output transformer of an inverter is applied. The integrator output signal is reset at the beginning of each period of the A.C. component of said current and is applied to a sample and hold stage whose output signal represents the integrator output signal just before it is reset. An intermediate stage is arranged between the integrator and the sample and hold stage to reduce the influence of load impacts by limiting the maximum possible variation of the output signal during the sampling period.

Abstract: The new device contains a vein chamber (4) in which a vein fragment (5) is clamped centrally with a slight axial prestress. 
<??>For the storage and transport of the vein fragment (5), the central area of the vein chamber (4), and thus the vein fragment (5) on the inside, can be filled with physiological saline via flow channels (21, 22). A drying-out of the vein fragment (5) is prevented by filling the peripheral area of the vein chamber (4) with a similar solution via flow paths (25, 26). 
<??>If, using hypodermic syringes (14, 16), the saline in the inside of the vein fragment (5) is replaced by an enzyme solution, a high percentage of the endothelial cells adhering to the inner wall of the vein fragment (5) can be obtained, without other cell types, such as fibroblasts or smooth muscle cells, being detached simultaneously from the wall of the vein fragment (5) and "contaminating" the endothelial cells whose proliferation is desired for coating alloplastic prostheses.
