Title: Method and reagent composition for subtyping lymphocytes in peripheral blood
Inventor: KIM YOUNG R
IPC: G01N33/53
Filed: 1992-06-02
Abstract: ABSTRACT      A rapid method for detection of monoclonal antibody labeled cells using forward light scatter/absorption clinical flow cytometers is disclosed.  Calf-intestinal alkaline phosphatase is conjugated to mouse monoclonal antibodies (anti-CD2, CD3, CD4, CD8, CD19) for direct immunoenzymatic labeling.  Red cells are pre-conditioned for lysis during the first incubation period with the alkaline phosphatase conjugated monoclonal antibodies by ammonium-sulfate which is followed by an early fixation of white cells in the presence of dextrose.  The combination of 5-bromo-4-chloro-3-indolyl phosphate and nitroblue-tetrazolium salt in diethanolamine buffer, containiny zinc glycinate, at pH 9.5?0.1, is used as a buffer/substrate to yield stable, insolu-ble and intense purplish precipitates on the surface of the cells labeled with alkaline phosphatase conjugated monoclonal antibodies.  The separation of granulocytes and lymphocytes is detected by a forward light scatter/absorption optics.  Endoge-nous alkaline phosphatase in granulocytes is inhibited with levamisole.  Early mild ixation of the white cells permits incubation at 35°C to 40°C which accelerates each step of the reaction without disrupting the cells throughout the procedure, making the procedure adaptable for use on automated cytometric instrumentation.

Abstract: In an adaptive matched filter with a decision feedback equalizer (DFE), a tap-weight controller of the matched filter includes a tapped delay line having a series of delay elements for receiving an incoming digital signal to produce successively delayed signals at successive taps of the delay line so that the signal at the center tap coincides with an output of the DFE. Cross-correlators are associated respectively with tap-weight multipliers of the matched filter. In each cross-correlator, cross-correlation is detected between a digital sample from the DFE and a delayed version of the corresponding digital sample. An average value is taken of the cross-correlation to produce higher significant bits of a tap-weight coefficient for the corresponding tap-weight multiplier. The most significant bit of the output of the higher significant bits is inverted and a group of bits is produced, each having the same binary value as the inverted most significant bit. The group of bits is supplied to the corresponding tap-weight multiplier as lower significant bits of the tap-weight coefficient..

Title: Master plate of optical memory device and manufacturing method thereof
Inventor: HIROKANE JUNJI
IPC: G11B7/24076
Filed: 1993-01-12
Abstract: A master plate of an optical memory device has a substrate having on a surface thereof a plurality of guiding grooves with a predetermined interval.   The respective edge portions of the guiding grooves are inclined with respect to the surface of the substrate at an angle not more than 30°. According to a manufacturing method for the master plate, the post-baking process is carried out at a baking temperature of not less than 150°C, and an etching gas containing °2 gas of 4 (SCCM) to 10 (SCCM) is used.  Thus, even when the copying is carried out with respect to the substrate of the optical memory device according to the injection molding process, wherein the stamper used is manufactured based on the above-mentioned master plate,  the mold release of the stamper can be carried out without being caught by the substrate.  Thus, it is possible to keep the respective shapes of the guiding grooves of the stamper, thereby enabling the substrate of the optical memory device to be manufactured with high repeatability.

Title: Spacing/levelling device
Inventor: MAKOW STAN P
IPC: E04F21/20
Filed: 1993-03-01
Abstract: ABSTRACT OF THE INVENTION   In the thin set laying of stone or ceramic tile, tiles are set by floating them over a uniformly applied screed of adhesive applied to a level substrate. In this invention combination spacing / levelling devices are used to equally space the corners of adjacent tiles and to maintain them at an equal elevation over the adhesive and substrate. The spacer/leveller device may comprise spacing fins and a guide for maintaining the corner of adjacent tiles flush while mortar is setting. The device works as a guide to facilitate level installation with uniform grout joints and it becomes part of the permanent fabric of the installation. Tiles are temporally supported by spacer/levellers at each corner (while adhesive is drying) and by virtue of the spacer/leveller design they are automatically flush to each other with equal joint spaces separating them. The invention substantially reduces the dependence on the skill of the tile layer to space tiles equally and set them on the same horizontal plane.

Abstract: A multi-functional, universal guide rail member is provided, for incorporation in an architectural joint system.  Typically, one such guide rail member is mounted on each of two adjacent, relatively movable structures and cooperates  with  pivotally  mounted  centering  bars  to maintain a covering plate in centered position.  The guide rail member incorporates in a single,  integral unit a continuous guide groove for the centering bars, an open-sided slot for receiving fastening means  (or,  in some cases,  caulking),  and  an  outwardly  facing  slot  for receiving anchoring means.  The multi-functional guide rail member is usefully employed in conjunction with standard off-the-shelf structural components, such as channels and angle members, to accommodate mounting of the guide rail members in a variety of architectural configurations.  In some architectural joint systems the multi-functional guide rail members may be employed in a manner making use of less than all of their functions, adding to the universality and economy of the system.
