IPC: C21D9/56
Filed: 1990-11-21
Abstract: Strip elongation in a continuous annealing furnace is controlled by passing the strip around a first driven roll, thence through a portion of the furnace, thence around a second driven roll, wherein the amount by which the peripheral speed of the second roll exceeds the peripheral speed of the first roll is controlled in order to control strip elongation.  Strip elongation is sensed by monitoring roll speeds using precision resolvers.  This eliminates the need to measure the strip load.

Title: Method and apparatus for enhancing the depth of focus in projection lithography
Inventor: HAKEY MARK C
IPC: G03F1/00
Filed: 1991-03-07
Abstract: METHOD AND APPARATUS FOR ENHANCING THE DEPTH OF FOCUS IN PROJECTION LITHOGRAPHY The invention provides a technique which enables projection lithography to extend to the sub-half micron range by compensating the Depth of Focus (DOF) budget lost in substrate topography with a projection of a non-planar image which is conformal to the substrate. The method of achieving a non-planar image field includes the formation of a mask reticle which is a replica of the surface of the semiconductor to be exposed, thus, eliminating substrate topography from the optical DOF budget.
Patent CA-2037906-A1 (CA)
Inventor: SCHAEFFER DENNIS R
IPC: H04B7/26
Filed: 1990-07-27
Abstract: A cellular radiotelephone communications system comprising a system of cells that are made up of an array of directional sector antennas. These antennas are centrally located in the cell and radiates into a 60° area of the cell. Each antenna in a cell has a group of frequencies assigned to it that is different than the group of frequencies assigned to the other antennas within that cell. These frequency groups are repeated either 2 or 8 times respectively in a 4 or 16 cell repeat pattern, effectively forming a two cell reuse pattern. The preferred embodiment of this invention is asymmetrically positioning the repeating frequency groups in an alternating fashion so that one row faces in the opposite direction of another row. The asymmetrical positioning of cells is possible only by departing from the prior art, cellular positioning rules. The positioning rules used in this invention create a 4 or 16 cell repeat pattern by locating co-channel cells closer in one direction than another.

Abstract: A portable transceiver and an ESN transfer system for a car telephone system.  The ESN and the MSN, which are manufacturer-controlled numbers, are stored in an EEPROM mounted on the panel of the portable transceiver.  When the panel on which the EEPROM is mounted is to be replaced, only the ESN is transferred to the EEPROM of the new panel.          Upon completion of the ESN transfer, the ESN in the EEPROM of the replaced panel is rewritten to data, which would make its specific part, such as the manufacturer's ID number, to be judged "incorrect".  No ESN whose specific part is "incorrect" can be transferred.  The ESN transfer unit, connected to a connector provided in the casing of the portable transceiver, performs said ESN transfer.
