Abstract: INCREASING OPTIONS IN LOCATING  ROM IN COMPUTER MEMORY SPACE                ABSTRACT            In order to more effectively use read only memory space of a personal computer system, ROM code is selectively located or mapped to either an address boundary which is an even or odd integer multiple of one half the capacity of the read only memory device in which the ROM code is stored.  The ROM code is stored in the read only memory device in two fields. In a first field, the ROM code is broken up into two segments, and the first segment precedes the second segment.  In the second field, the same two segments are stored, but the second segment is stored preceding the first segment.  A register, for storing page select bits, provides an input to an address decoder and an input to an adder, which adds unity to the contents of the register and provides its outputs to the address decoder as well.  Accordingly, the address decoder- will respond to either the page which is identified by the page select bits or the page following the identified page.  The LSB of the page select bits is used in addressing the read only memory device to select between the first field (selected when the LSB is zero) or the second field (selected when the LSB is unity).

Abstract: An indirect frequency synthesizer suitable for use in a cellular radio system has finer resolution and reduced spurious frequencies and/or phase noise, which facilitates a large number of channels in a given bandwidth. The synthesizer comprises a phase detector responsive to a reference signal and a phase control signal for generating a control signal that varies in dependence upon the phase difference between the reference signal and the phase control signal. A voltage controlled oscillator responsive to the control signal generates an output signal whose frequency varies in dependence upon the control signal. A variable modulus divider divides the output signal to provide the phase control signal. The variable modulus divider varies its division ratio in dependence upon a ratio control signal derived by a second or higher order sigma-delta modulator in response to a frequency control signal .delta..PHI. and to the phase control signal.      The sigma-delta modulator displaces any quantisation noise in the ratio control signal away from the frequency of the phase control signal and multiples thereof. A direct frequency synthesizer may be implemented by means of the same sigma-delta modulator and variable modulus divider, but arranged so that the reference frequency signal is applied to the input of the divider, which divides it directly to provide the desired output frequency.

IPC: G01V1/44
Filed: 1990-03-15
Granted: 1998-12-01
Abstract: An acoustic borehole logging tool traverses a fluid-filled cased well with an acoustic energy transmitter.  Pressure waves created in the well fluid by the transmitter generate tube waves in the well casing.  A closely spaced receiver detects tube waves that have travelled along the cased wellbore and been reflected by fracture interfaces.  These reflected tube waves are recorded and used to identify the top and bottom of any fracture interval in the formation behind the well casing. This method can also be applied to determination of the effectiveness of a hydraulic fracturing operation in a subsurface formation behind a well casing.

Title: Method and apparatus for improved melt flow during continuous strip casting
Inventor: FOLLSTAEDT DONALD W
IPC: B22D11/06
Filed: 1990-10-02
Granted: 2002-02-19
Abstract: The continuous casting of metal strip using the melt overflow process is improved by controlling the weir conditions in the nozzle to provide a more uniform flow of molten metal across the width of the nozzle and reducing the tendency for freezing of metal along the interface with refractory surfaces. A weir design having a sloped rear wall and tapered sidewalls and critical gap controls beneath the weir has resulted in the drastic reduction in edge tearing and a significant improvement in strip uniformity. The floor of the container vessel is preferably sloped and the gap between the nozzle and the rotating substrate is critically controlled. The resulting flow patterns observed with the improved casting process have reduced thermal gradients in the bath, contained surface slag and eliminated undesirable solidification near the discharge area by increasing the flow rates at those points.

Title: Method and equipment for the immediate target call allocation in lift groups by reason of operating costs and of variable bonus and penalty point factors
Inventor: SCHRODER JORIS
IPC: B66B1/18
Filed: 1991-02-07
Granted: 2004-11-02
Abstract: In this method, target calls (R~~) are definitively allocated immediately to the individual lifts (N) for serving of the call by reason of higher rank and lower rank function requirements and these allocations are indicated immediately on the input storeys (E1 to E16). For this purpose, a weighted sum corresponding to higher rank function requirements is formed from partial operating costs (K1 to K n), this sum is modified into operating costs (K NR) in the sense of lower rank function requirements by means of variable bonus and penalty point factors (BF1...; MF1...) and a target call (R~~) is allocated to the lift (N) with the lowest operating costs (K NR). A target call allocation algorithm (ZZA) according to steps 1 to 6 (SR1 to SR6) with subordinate algorithms for the bonus and penalty point tracking (NFA) and the costs computation (KBA) serves for implementation of this method. The bonus and penalty point factors (BF1...; MF1...) are continuously made to follow the traffic volume or the cage load group by group or lift by lift with the tracking algorithm (NFA).      The computation of the operating costs (K NR) takes place in the costs computation algorithm (KBA) according to a special costs formula, wherein the re-adjusted bonus and penalty point factors (BF1...; MF1...) act multiplicatively on a six-part partial costs sum. This allocation procedure improves above all the user friendliness and the quantitative aspects "waiting times" and "times to target". It utilises capacity reserves at low traffic for additional function requirements on the serving of calls.

IPC: G11C7/00
Filed: 1991-02-20
Granted: 1994-07-26
Abstract: There is provided a magnetooptic device comprising: a substrate; a semiconductor layer having a quantum well structure formed on the substrate, in which the semiconductor layer is formed by alternately laminating a well layer and a barrier layer and at least the barrier layer in those layers contains magnetic ions; and electrodes to apply an electric field to the semiconductor layer.  A light which was polarized in a predetermined direction is input to the semiconductor layer.  A magnetic field is applied to the semiconductor layer.  An electric field is applied to the semiconductor layer by the electrodes.  The light which was transmitted in the semiconductor layer is extracted.  A degree of leakage of a wave function of the carrier in the well layer into the barrier layer changes.  An effective magnetic field which a carrier spin feels changes by an exchange interaction between the carrier spin and a magnetic moment associated with the magnetic ions.  Thus, a degree of magnetooptic effect which is given to the transmission light changes.  The degree of manetooptic effect can be controlled by the applied electric field.          The magnetooptic device is preferably used as an optical modulator or an optical isolator in the field of optical communication or optical memory.

Granted: 2003-07-01
Abstract: A toothbrush whose tufts comprise three distinct groups of rows, with each row oriented transversely to the longitudinal axis of the head. The tufts of the first group are the shortest. The endmost tufts on each row of the second kind tilt laterally outwardly by about 12 degrees. The tufts of the third group are nearest the end of the head farthest from the handle and diverge from each other.        In one embodiment, each tuft of the third kind tilts laterally at an angle of about 30 degrees and forwardly at about 14 degrees.        In a first embodiment, each row of the first group comprises a single, wide tint. In a second embodiment, each row of the first group has a plurality of laterally spaced round tufts. In a third embodiment, each row of the first group comprises a plurality of laterally spaced quadrangular tufts. All of the tufts may also be considered as defining four functional groups of tufts, with each of these four groups performing a specific function during brushing. The arrangement and orientation of the tufts yields a uniform cleaning action substantially independent of brushing direction or technique.

Granted: 2002-01-01
Abstract: A portable scanning head emits and receives light from a light-emitting diode to read symbols, such as bar-code symbols. The optics within the scanner are operative for focusing a light beam and the view of a light sensor in different planes exteriorly of a scanner housing, Imaging means are provided in the unit for imaging a viewing window. The viewing window has an area smaller than that of the scan spot. The system can employ an LED as a light source and tolerate the relatively large-sized (on the order of millimeters) scan spot without sacrificing reading performance since the photodiode "sees" only that portion of the scan spot visible through the viewing window.
