Title: Display control device
Inventor: KOSUGI SATOSHI
IPC: G09G5/00
Filed: 1990-10-01
Abstract: Abstract of the Disclosure:    A display control device according to the present invention includes a common memory having two funtions, one as a refresh memory for outputting a character code and the other as a character generator for generating a character font, an output character code from which is stored in a line buffer.  In this case, a display address generator circuit generates a character address for generating the character code and a raster address for designating the character font, which are in turn switched by an address selector and outputted to said common memory which then outputs a video signal to a video control circuit based upon said character font.  Additionally, there is provided a line buffer control circuit for outputting a read/write access control signal to said line buffer based upon the raster address.

Title: Method of recovering hydrocarbons using single well injection/production system
IPC: E21B43/24
Filed: 1990-12-07
Abstract: Production of viscous hydrocarbons is initiated by first injecting an injection fluid down at least two tubing strings in a wellbore having multiple tubing strings therein.  Following an initiation phase, flow of injection fluid in the production tubing string is ceased, and production of formation fluid to the surface commenced in the heated tubing.  The production of formation fluids is controlled, and entry of uncondensed steam from the forma-tion into the wellbore avoided by maintaining a liquid level in the formation which is above the production perforations.

Title: Position and heading detecting device for self controlled vehicle
Inventor: NINOMIYA YOSHIKI
IPC: G05D1/02
Filed: 1990-12-28
Abstract: ABSTRACT     An outer environment of the vehicle is inputted in image.   Image processing is performed to the input image, and many edge segments are extracted.   The edge segments are clustered in every edge segments which seem to exist on the same line.   Matching is operated in a respective   set   of   plural   longer   edge   segments representing plural  clusters  in correspondence with  a set of plural guide signs as standards of guide of the vehicle mapped on the image input surface, and a set of longer edge segments being most matched each other  is extracted.  From position and headings of the extracted longer edge segments on the  image  input  surface,  the position  and  heading  in  the  outer  environment  are calculated.  The position and heading of the vehicle is detected from these values.  The position and heading of the  vehicle  obtained  in  the  above-mentioned  image processing and the position and heading of the vehicle measured  by  other  means  are  evaluated  synthetically.        When  the  guide  signs  are  mapped  on  the  image  input surface, the forecast values of position and heading of the vehicle at the image input time are used.  According to these means,  the detecting accuracy of the position and heading of the vehicle is improved.

Title: High capacity viscous pumping groove pattern for a wet clutch
Inventor: PAYVAR PARVIZ
IPC: F16D13/74
Filed: 1991-01-24
Abstract: A HIGH CAPACITY VISCOUS PUMPING GROOVE PATTERN      FOR WET CLUTCH              ABSTRACT OF THE DISCLOSURE       A groove pattern for the paper-based friction facing on a wet clutch to equalize the surface temperature of the friction facings and thus increase the thermal capacity of the clutch where there is continuous slippage.  The groove pattern includes one or more continuous annular grooves dividing the friction area into two or more annular bands and a plurality of cross grooves in each band which are angled with respect to a radius of the facing.  The angled cross grooves increase in number in each band from the inner band to the outer band.  The angled cross grooves extend at an acute angle (10-50 degrees) to such radius. Slip of the friction pair of plates causes a viscous pumping action.  The cross groove angle in each band of the facing is preferably different so as to keep all the grooves filled with cooling oil, and the cross-section of the cross grooves vary in their dimensions as between the bands.  The disclosed 60° waffle pattern includes annular bands and cross grooves extending from the inner to outer perimeters of the facing at an angle of 60 degrees to the radius of the metal clutch plate.  The angled cross grooves of this pattern also provides viscous pumping of oil through the facing.

Patent CA-2048451-A1 (CA)
Inventor: FOLEY DANIEL M
IPC: A01B73/00
Filed: 1991-08-06
Abstract: Lift arms on a gang of implements support transport wheels which are movable from a raised field-working position to a lowered endwise towing position.  Several of the wheels at the forward and aft ends of the towed gang of implements are fitted with castering pivots located adjacent the wheel hubs close to the wheel centerlines to lessen side loading and tire scuffing during turns.  The castering wheels include a caster control assembly having at least four functions. First, a lock feature includes a spring-biased pin selectively engageable with the control assembly to secure the wheels in an in-line position to permit easy backing of the implements in the towing configuration.  Second, a contact on the implement frame which engages the caster control assembly when the wheels are raised off the ground, cams the caster wheel to a preselected field-working position and prevents rocking of the wheel.  Third, a bellevue washer on the caster control assembly limits shimmying of the wheel during transport. Fourth, the caster control assembly cooperates with a stop member on the lift arm to limit the angle through which the wheel can pivot.  Combinations of caster wheel and non-caster wheel lift arm arrangements to reduce side loads and wheel scuffing while providing towing stability include two forwardmost caster wheels with all remaining wheels uncastered when three or four implements are towed endwise.  When five or more implements are towed endwise, the first two wheels and the last wheel are castered, with an additional central caster wheel provided on a six-unit arrangement.

Abstract: The  invention comprises a closure  for carton board containers which is an extension of the top flap.  A dispensing opening is partially die cut through an end wall of the container, thereby forming an opening with a remov-able plug.  The plug is glued to the closure flap so that it comes away with and is a functional part of the closure flap.   A locking tab depends from a lower edge of the closure flap and is spot glued to the end wall when the container is initially filled.   The closure is initially opened by pulling on the tab and breaking the spot seal. A pair of score lines extend across the closure flap on the one hand and adjacent to the tab on the other to facilitate closing  and  locking.    In  an alternate  embodiment,  an additional  top mirror end flap is provided to enhance carton sealing and product containment.

Inventor: AGRAWAL SUDHIR
IPC: C40B40/06
Filed: 1990-04-05
Abstract: A method of producing synthetic oligonucleotides on a small or large scale using H-phosphonate nucleoside monomers is described.  The method can be used to synthesize oligonucleotides of any length, including oligodeoxyribonucleotides and oligoribonucleotides.  The method results in a coupling efficiency of greater than 97 %  and consumes only two to three equivalents of monomer to activator per coupling reaction. In addition, the method does not require a separate capping step and capping reagent because the activating reagent serves a self-capping function thereby preventing elongation of failed sequences. The H-phosphonate linkages of the fully synthesized oligonucleotide can be oxidized with a variety of reagents to obtain either phosphate diester or other types of modified oligonucleotides.
