Abstract: Coherent electron beams are used to irradiate an electron beam resist film (9), thereby to expose the film (9) with a predetermined pattern. After processing of the film (9) layers (6,7) below the film (9) can be etched then used as a mask to implant ions into further layers (2,3,4,5). Where one (4) of these layers is e.g. an active layer of a semiconductor laser, the result is that quantum wires (l3) may be formed with a cross-section of 50 nm × 50 nm or less, thereby permitting the production of a laser with a low threshold current. The process is applicable to other devices, and permits sub-micron patterns to be formed accurately with dimensions of 3 to 50 nm.

Title: Chain extended urethane diacrylate and dental impression formation
Inventor: HARE PAMELA H
IPC: A61K6/893
Filed: 1987-11-24
Abstract: Disclosed is a new urethane polyacrylate having at least one terminal isocyanato acrylic pendent radical. Preferably the molecular chain within the acrylate caps has been extended with a polyhydroxy compound just before final end capping with isocyanato acrylic. The isocyanato acrylic is preferably isocyanato ethyl methacrylate and the urethane is diisocyanate capped polyether and the polyether radical is oxyalkylene. The method for producing the urethane polyacrylate involves end capping a polyol with diisocyanate yielding a reaction product with two reactive equivalents of isocyanate and then capping less than all of the isocyanate with a hydroxyacrylate, after which the remaining isocyanate is reacted with polyol to provide chain extension. The chain extending polyol is then capped with a isocyanato acrylic. Also disclosed is a new impression material for application to mammalian tissue and curing in contact therewith; the impression material including a free radical polymerizable resin, alkyl benzensulfonyl titanate, polymerization initiator, and filler; and a method of use.

Abstract: Control signal reliability across an I/O limited high-speed data transmission interface is assured by time-sequenced transmission of control signals and parity signals. Two sets of control signals (CNTLA,CNTLB) are transferred in opposing directions across the data transmission interface in a first data transfer period, during which their joint parity is determined and latched on each side of the interface, and the result of one latched joint parity determination is transmitted across the interface. During the following data transfer period, the transmitted parity is compared with the other joint parity determination, the results of the compa­rison being used to detect transmission errors in the control signals.

Abstract: A non-invasive method and equipment for the evaluation of the flexibility of the spine of a patient and, as a result of this evaluation, the detection and identification of possible mechanical injuries in the lumbar portion of this spine. According to this method, a string of skin-markers is fixed onto the skin of the back of the patient in the midline of his spine from at least cervical vertebra C₇ down to at least sacral vertebra S₃. Two other skin-markers are fixed onto the skin of the back of the patient in a bilateral and symmetrical manner on the crests of his ilium. The relative positions of all the skin-­markers are then monitored and recorded as he flexes forward in this sagittal plane and the so recorded positions are processed to determine (1) the angle of flexion α of the patient, this angle α being indicative of the combined motion of both hip and spine of the patient, (2) the angle of rotation "h" of the hip and (3) the actual contribution of the spine to the total flexion of the patient, this contribution, expressed as angle "s", being indicative of the spine motion of the patient.

Abstract: A conventional three-electrode wedge-and-strip pattern in a digitizer tablet surface is used with a conventional cursor or stylus. A phantom cursor electrode is located at predetermined coordinates of the active area of the digitizer tablet beneath the X, Y and balance (B) electrodes and separated therefrom by a layer of dielectric material, preferably an air gap. Prior to use of the digitizer apparatus, the phantom cursor electrode is electrostatically coupled to the X, Y and B electrodes in order to obtain data signals representing the phantom cursor's measured coordinates without compensation for resolution distortion. A microprocessor produces a correction factor using the data signals and the predefined coordinates of the phantom cursor electrode, which correction factor is applied in normal use to compensate for resolution distortion resulting from the unavoidable gaps between the X, Y and B electrodes. Also raw measured data obtained from the electrostatically coupled electrodes is adjusted to compensate for environmental and inherent noise and an offset corresponding to the difference in the reference potentials of the integrator and comparator.
