Title: Direct current traveling wave motor
Inventor: CULP GORDON W
IPC: H01L41/09
Filed: 1991-02-01
Abstract: ABSTRACT OF THE DISCLOSURE A direct current traveling wave motor generates motive force by utilizing shear deformation resulting from electrical contact between a rolling element and a layer of material that experiences shear deformation in response to an applied electric field. In a rotary piezoelectric embodiment, rotation of a motor shaft results from the non-uniform electric field intensity around the contacts between rollers surrounding the shaft and an outer race of piezoelectric material that undergoes shear deformation. Rotation occurs as the rollers roll down the faces of piezoelectric shear waves that travel with the rollers. The rollers perform the function of commutators, but without sliding friction, and they eliminate the need for traditional roller bearings. Zero clearance between motor parts results in shaft stiffness that allows precise positioning and high speed operation. The piezoelectric motor has high efficiency because sliding friction is eliminated, eddy currents are not generated, and most of the internally flowing current is local and reactive. Efficiency of the motor exceeds 98%, and its silent, smooth operation is capable of very high speeds. Speed of the motor is controlled by varying the DC potential. The motor may be operated by a battery, it does not require lubrication, and it will operate while flooded with slightly conducting fluids, such as salt water. The scale of the motor can range from miniature for driving a watch to very large for driving an oceangoing ship.

Title: Id card issuing system
Inventor: HAKAMATSUKA MIYUKI
IPC: G06F17/24
Filed: 1990-08-22
Abstract: ABSTRACT    A plurality of different kinds of information, for example, full color photographic image information and attribute information such as a name, date of birth, etc., are input by use of a CCD scanner (1a), a camera (1b), a keyboard (1c), a mouse (1d), etc., with coordinate information assigned to each piece of information.  The input pieces of information are matched with each other with reference to the coordinate information, and an arrangement of the coordinated information is determined with reference to layout information prepared separately, and then the information is printed out onto a card substrate.  Thus, an ID card can be made accurately and efficiently.  In addition, forgery prevention processing is applied by simultaneously inputting forgery prevention information and further falsification prevention processing is applied by carrying out emboss processing, thereby enabling an improvement in the security of the ID card.     In addition, it is possible to prevent the making of forged cards and the undesired issue of cards which are not conformable to a particular production purpose by adding a special pattern (113) to a blank card (110) and applying print processing thereto after recognizing the special pattern by a card processing machine (112).

IPC: G11B7/24097
Filed: 1991-11-15
Abstract: An optical disk according to the present invention has thereon an uninterrupted preformed groove adjoining a track.  The address information of the track and sectors is prerecorded by variations in the preformed groove in a radial direction of the optical disk.  An optical disk drive converts a detection signal, that is generated when the spot of a light beam crosses the track, into a binary signal  in  accordance  with  the  comparison  between  the detection signal and two different slice levels, whereby a correct  track  crossing  number  is  obtained.   Another optical disk has thereon index marks that are prerecorded by partially varying the width of the preformed groove.          Another optical disk drive detects the index mark on a specific track line, whereby formatting data with respect to address information is generated.  The optical disks and optical disk drives are thus compatible with writing of the address information by means of soft-formatting.

Patent CA-2058490-A1 (CA)
IPC: F25J3/04
Filed: 1991-12-27
Abstract: This invention relates to a cryogenic process for the separation of air utilizing an integrated multi-column distillation system wherein an ultra high purity nitrogen product is generated.  In the cryogenic distillation separation of air, air is initially compressed, pretreated and cooled for separation into its components.  Ultra high purity, e.g., nitrogen typically having less than 0.1 ppm impurities is generated in a multi-column distillation system comprising a first column and an ultra high purity nitrogen column with enhanced nitrogen product recovery by withdrawing a gaseous nitrogen fraction from a first column and charging that fraction as a feed to the ultra high purity nitrogen column, withdrawing a nitrogen stream which is rich in volatile contaminants from the top of the ultra high purity nitrogen column and recovering a nitrogen product at a point below the removal point of the nitrogen rich stream containing volatile components.  Removal of volatile components in the distillation process is effected by partially condensing a nitrogen vapor stream from either the first column or the ultra high purity column and removing at least one of the uncondensed portions of the nitrogen rich stream containing volatile components as a purge stream.

Title: Diltiazem formulation
Inventor: HENDRICKSON DENNIS L
IPC: A61P9/10
Filed: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE The present invention is directed to a diltiazem for-mulation suitable for one a day administration. The for-mulation contains a blend of diltiazem beads having two differing dissolution profiles. One type of bead is a rapid release bead which releases up to 100% of the dil-tiazem it contains within approximately 6 to 8 hours of administration. The second bead is a delayed release diltiazem bead and substantial quantities of diltiazem are not released from this bead until approximately 12 hours after administration with the majority of the dil-tiazem being released at 16 to 24 hours after administra-tion. The diltiazem formulation will typically contain from 25% to 60% w/w of the rapid release beads and from 40% to 75% w/w of the delayed release beads. Both the rapid release and the delayed release beads are made up of two parts, one being a central core containing the diltiazem while the other is a polymeric coating which envelops the central core.

Abstract: A method and apparatus for simulating the effect of non-homogeneous fog in an image displayed on a screen. The image is intended to represent the appearance of a model defined in a database in world space coordinate; from an eyepoint position in world space, the model being defined in terms of individual features each having predetermined attributes defining the position and visible characteristics of the feature. Image data is derived from the model for each of an array of sampling points distributed across screen space. A non-homogeneous fog structure is defined world space coordinates as a series of parallel strata of predetermined extinction coefficient. The positions of the eyepoint and a feature to be displayed relative to the fog structure are determined. The distance from the feature to the eyepoint is calculated. An average value of the extinction coefficient between the eyepoint and the feature is calculated from the defined parallel strata, and the attributes are modulated as a function of the calculated distance and the calculated average value of the extinction coefficient.
