Inventor: SATOW JUN
IPC: C07D413/10
Filed: 1991-01-10
Granted: 2001-02-20
Abstract: Disclosed herein is uracil derivatives having a trifluoromethyl group at the 6-position and a phenyl group at the 3-position which has a NHSO2D26 group at 5-position of the benzene ring, halogen atom at 4-position thereof and hydrogen atom or halogen atom at 2-position thereof, which are represented by the formula (I) shown below.    wherein R7 represents hydrogen, fluorine or chlorine;      R8 represents chlorine; and D26 represents methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, sec-butyl, t-butyl, CH2CF3 or CH2CH2CH2Cl.   Compounds of the invention show penetrative translocation activity, a very high herbicidal activity and, particularly, no phytotoxicity against soybean, in which as compared with the conventional herbicidal compounds, the said uracil derivatives can be applied for either soil treatment or soil incorporation treatment, thereby producing a quick and high herbicidal effect even at a very low dosage against a large variety of weeds including perennial weeds, and have the property to residual effect for an appropriate period of time.

Title: System for carrying a charge in a reheating furnace
Inventor: HEUSS HELMUT
IPC: F27D3/02
Filed: 1991-01-23
Granted: 1996-02-06
Abstract: The system comprises at least one coolant-carrying tubular support carrying at least one rider. The latter consists of a heat-resistant cast housing provided with at least one cutout into which a ceramic carrier is inserted. The carrier is of sufficient compressive strength even at a temperature in excess of 1,200 °C. The housing remains at a temperature below 1,200 °C and therefore provides a very good support for the carrier which it holds and transfers the loads that occur into the tubular support. The housing is detachably connected with the tubular support by means of a bolt.

Abstract: Dispositif d'affichage vidéo comprenant un générateur de données vidéo qui génère des données vidéo d'une image fixe et d'une image en mouvement (données graphiques) en utilisant une structure d'image fixe, un code de caractère d'image fixe, un code de caractère d'image en mouvement et d'autres éléments préprogrammés dans une mémoire externe. Utilisant des données de priorité pour l'image fixe et pour l'image en mouvement ainsi que des données de mode, les unes et les autres préprogrammées en mémoire externe, un microprocesseur applique les premières données de priorité aux données vidéo du caractère d'image fixe et les secondes données de priorité aux données vidéo du caractère d'image en mouvement. Un codeur de priorité sélectionne un caractère d'image fixe ou un caractère d'image en mouvement ayant la plus haute priorité, en fonction des premières et des secondes données de priorité, et transmet le numéro de ce caractère à un décodeur. Le décodeur produit un signal de commande de porte correspondant au numéro. En réponse au signal de commande de porte, les données vidéo du caractère ayant la plus haute priorité, entre le caractère d'image fixe et le caractère d'image en mouvement, sont produites à une porte.

Abstract: A tyre is progressively constructed by the build up of the constituent parts on a support. The reinforcement, as a single wire of the appropriate material, textile or metal, is fed over the support. One fixed length section of the wire is placed over the support, perpendicular to a radius and at the required angle. It is radially flattened against the support by the action of two forming means each side of the support. The forming means have a cyclic movement from the top level of the support descending and approaching the support in the direction of its axes of rotation, during which the section of wire is gripped; by stops mounted on a belt passing over two pulleys; and flattened against the support.

IPC: F16H61/14
Filed: 1992-09-02
Granted: 1997-04-15
Abstract: A system for controlling a lock-up clutch of a torque converter in which a target speed ratio of the torque con-verter is determined by carrying out a fuzzy reasoning based on fuzzy production rules using a degree of throttle open-ing, a grade resistance and a current speed ratio as parame-ters.  Then a second fuzzy reasoning is carried out based on second fuzzy production rules using a deviation between the target speed ratio and the current speed ratio and the change of the deviation as parameters to determine a control value such that the lock-up clutch is controlled between a position at which the clutch is fully engaged and a position at which the clutch is fully not engaged including an in-termediate position at which the clutch is partially en-gaged.  With the arrangement, the lock-up control can cope with various vehicle operating conditions so that the driva-bility and fuel consumption is improved while suppressing engine noise.  The arrangement further enables the control that is better matched to the intention, descision-making, and feelings of a human driver.

Abstract: A motor-driven drive shaft (12) is coupled to a grinding mill (4) or other unbalanced rotatable member through a clutch (5) arranged to accommodate misalignment, the clutch being so controlled during start-up as to be initially engaged to effect a limit-ed preliminary rotation of the mill in the drive direction, then disengaged to permit the mill to rotate under its own weight through a first rotation in the direction reverse to the drive direction and through a second rotation in the drive direction, and then to be re-engaged during the second rotation of the member in the drive direction. Clutch orbiting is thus reduced if not elimi-nated.

Abstract: An opposed wiping type wiper unit has a crank arm which rotates with driving of a motor, an intermediate link connected to right- and left-hand wiper shafts through driving rods, and a connecting rod for connecting the crank arm and the intermediate link.   The length of the connecting rod and the connecting position thereof to the intermediate link are set so that the actual angular acceleration change of the intermediate link is substantially symmetrical, and the angular velocity changes of right- and left-hand wiper arms are made asymmetrical on the basis of the set length of the driving rods and the set connecting positions thereof to the intermediate link.   Thus, the opposed wiping type wiper unit can easily be designed in accordance with specifications, and permits the use of as many parts common to the specifications as possible, thereby decreasing the cost.

Title: Process for heating an asphalt surface and apparatus therefor
Inventor: WILEY PATRICK C
IPC: E01C23/14
Filed: 1994-09-02
Granted: 2003-11-11
Abstract: A process for heating an asphalt surface and an apparatus therefor.      The process comprises the steps of: igniting in a burner a combustible mixture comprised of a fuel and oxygen to produce a hot gas; and feeding the hot gas to an enclosure having a radiative face disposed above the asphalt surface. The asphalt surface heating apparatus comprises a hot gas producing burner and an enclosure comprising an inlet for receiving hot gas from the burner and a radiative face having a plurality of apertures.  The apertures in the radiative face are of a dimension such that the hot gas: (i) heats the radiative face to provide radiation heat transfer to the asphalt surface; and (ii) passes through the apertures to provide convection heat transfer to the asphalt surface. The radiation heat transfer is from about 20% to about 80% of a total heat transfer, the remainder being convection heat transfer. This arrangement allows for improved efficiency of heating and asphalt surface.
