Title: Autonomous vehicle guidance system
Inventor: TORII TSUYOSHI
IPC: G05D1/02
Filed: 1995-02-13
Abstract: In a differential GPS system, the position of a vehicle eg a mower is determined by position information from satellites 70 combined with correction information based on the position data of a known point 30. The position of the vehicle is also determined 52 from the route history since the reference point. The difference between the position data from satellites and the position data based on the route history at each moment when the position data is received from satellites, is calculated and the differences are averaged to obtain a correction value. Finally the current position of the vehicle is calculated by correcting the position data based on the route history by the newest correction value. Consequently, in the autonomous running control system the position of the vehicle can be determined accurately without stopping the vehicle, even when the position data from satellites does not have sufficient accuracy. <IMAGE>

Title: Bonding of flip-chip i.c. dies to a substrate
Inventor: MALONEY CONRAD RAYMOND CREWE
IPC: H01L23/485
Filed: 1995-06-07
Abstract: An integrated circuit die 2 has exposed regions on its upper surface of aluminium on which forms an oxide layer 13. The oxide layer 13 is etched away to form windows 12 onto the underlying aluminium regions 10. A conductive, protective layer 14 of titanium nitride is sputtered on the upper surface of the die; pads 7 of a conductive thermoplastic 15 are then deposited over the windows 12. The titanium nitride layer 14 is subsequently removed by etching, except where it is protected by the pads 7. The die 2 can then be flipped over and joined to a substrate 1 by making electrical connection between the pads 7 and conductive regions 8 on the substrate. <MATH>

Title: Method of operating a recording apparatus
Inventor: TANI TATSUO
IPC: G03G15/00
Filed: 1993-07-01
Abstract: A recording apparatus is operated in two recording modes, in a first mode one image page is recorded on one or both sides of a sheet, in the second two image pages are recorded on each side of the sheet. The sheets that have been recorded on are then bound either in the centre or at an edge. The order in which it is necessary to stack the sheets depending on the recording mode and bind mode are determined by a control unit (127, Fig. 16) a page number signal generating device (190) and a control sequence (illustrated in Figs. 17A and 17B by flow charts). The apparatus uses an intermediate tray 48 and a turning section 25 to ensure the correct sheets are passed to a stapling tray 50 with a movable end stop 52 for edge or centre binding. A folder 56 can be provided between the stapler and a discharge tray 41.

Title: Method of making bioprosthetic conduit, mould therefor and conduit so formed
Inventor: BODNAR ENDRE
IPC: A61F2/06
Filed: 1996-04-24
Abstract: The method comprises the steps of:  (a) taking a cylindrical mould, having circumferentially spaced protuberances 2 which extend radially from the axis; (b) curving a layer of a biocompatible sheet material 3 around the cylindrical mould, and joining the opposed edges of the layer together along a longitudinal axis, parallel to the axis of the mould to form a tubular layer; and (c) removing the tubular layer from the mould and turning it inside out to form a cylindrical conduit with sinuses, the conduit being fully fixed by a chemical means; after removal or while still on the mould.  Where the conduit is required to be valved, in an additional step (d) an outer biocompatible layer 4 is overlaid on the underlying tubular layer to form a superimposed layer, so that the superimposed layer partially covers the protuberances 2, the superimposed layer is held in place and sealed onto the underlying tubular layer around the protuberances, to form sinuses and cusps or valve flaps, the layers being partially fixed on the mould by a chemical means. The mould is collapsible or soluble.

Title: Friction clutch equipped with a pulse generator providing speed indicative signals
Inventor: SCHULZ-ANDRES HEIKO
IPC: F16D13/60
Filed: 1996-08-28
Abstract: A friction clutch employs a flywheel (1) attachable to a drive, a housing (5) for mounting a pressing spring (8) and a pressing plate (9) for engaging friction linings (3, 4) of a clutch disc assembly (10). A ring component (12) surrounds the axis of rotation of the flywheel (1) and the housing (5) and has markings (14) detectable by a pulse generator (15). The ring component (12) is deformable by small radial forces because of its thinness in radial direction so that with respect to its inner diameter it can be adjusted by expanding or shrinking on a mounting component, such as the flywheel (1) or the housing (5), to form a frictional connection therewith. In a second embodiment the ring component is an integral part of an extension of the housing.

Abstract: The invention proposes a new and improved way of providing a replaceable point; it suggests that the dart body/barrel (11) be made as a tube, with an axial opening extending along it from the flight end to the tip end, the opening being narrower, and preferably stepped (12), at the tip end so that a new point (14) shaped like a dressmaker's pin - that is, a pointed shaft (15) with a "head" (16) at the non-pointed end - can be inserted into the body (11) and pushed down to be secured, by the flight (17) that carries the dart's vanes (18) on a screw-in rod (19), with its head (16) in the body's tip end and the pointed shaft (15) projecting from the end to make the new dart point. The dart body (11) may be made of plastic, and, in the case of a full-size dart may include an insert weight.

IPC: E02D19/18
Filed: 1995-04-24
Abstract: A trench (18) is excavated from the top surface of an earthen dike (10), all the way down to the foundation below the base of the dike. Dry powder, partially hydrolyzed polyacrylamide (PHPA) is mixed with fresh water and soda ash in proportions of 20 pounds PHPA to 4 pounds soda ash to 68 barrels (2856 gallons) fresh water to form a slurry (40) having a funnel viscosity of at least 45 seconds/quart. As the trench is being excavated, the slurry is pumped into the trench immediately. A section of geo-membrane (20) having a thickness of 0.080 inch is placed in the trench all the way to the bottom of the trench, overlapping at the top of the membrane onto the top surface (11) of the dike. Dry sand (42) is then pumped into the trench to displace the slurry in the trench.

The phytase may be obtained from soybean extract (or fractions thereof), soya flour or germinated soybeans (or parts thereof) by sequential treatment processes, involving ammonium sulphate precipitation (from 50 to 70%), anion-exchange chromatography and cation-exchange chromatograpy. DNA, encoding said phytase, which may be in a vector for the transformation of a host cell, is described. The host cell may be prokaryotic (preferably Escherichia coli, Bacillus sp., Lactobacillus sp. or Lactococcus sp.), or eukaryotic (preferably either a fungus selected from Aspergillus, Trichoderma , Mucor , Kluyveromyces or Saccharomyces , or a plant (including seeds) selected from soybean, corn or rapeseed). The phytase is of use in (animal) feedstuffs, either to reduce the environmental impact of phosphorous from livestock production, or to reduce the multivalent metal ion binding anti-nutritional effect of phytate.

Inventor: LEE JAE-KON
IPC: H03L7/099
Filed: 1997-02-06
Abstract: The present invention relates to a digital phase correcting apparatus, including a phase comparator, a loop filter and a digital controlled oscillator. The digital controlled oscillator includes a phase clock signal generator 400 inputting the master clock signal and for generating a clock signal having a phase difference of half a period of the master clock signal, a multiplexer 410 for selecting and outputting one of the clock signals generated in the phase clock signal generator, an up/down counter 430 for receiving a phase lead/lag signal of the loop filter and providing an output select signal for the multiplexer 410 and a frequency divider 420 for dividing the frequency of the clock signal output from the multiplexer 410 and outputting the phase locked clock signal to the phase comparator 100. According to the present invention, it is possible to improve the degree of precision and the jitter characteristics of the PLL by a factor of two since the phase locked clock signal can be changed by a half period unit of the master clock signal.
