Title: Ignition timing control system and method, and engine control unit for internal combustion engine
Inventor: KATAGIRI YOSHIHIRO
IPC: F02D29/00
Filed: 2002-08-09
Abstract: There is provided an ignition timing control system and method and an engine control unit for an internal combustion engine, which are capable of setting optimum timing for execution of retardation of ignition timing when a vehicle on which the engines is installed is accelerated, thereby effectively reducing longitudinal vibrations of the vehicle, which might be caused by torque fluctuations, and maintaining acceleration performance. An acceleration demand-detecting module detects a demand of acceleration of the engine. A rotational speed-detecting module detects a rotational speed of the engine. A rotational variation amount-calculating module calculates a variation amount of the rotational speed of the engine, based on the detected rotational speed of the engine. A rotational variation amount differential value-calculating module calculates a differential value of the variation amount of the rotational speed of the engine, based on the calculated variation amount of the rotational speed of the engine. A retard amount-calculating module calculates a retard amount for retarding the ignition timing. A retardation execution module executes retardation of the ignition timing by the retard amount, on condition that the demand of the acceleration is detected, that the variation amount of the rotational speed of the engine is larger than a predetermined amount, and that the differential value of the variation amount of the rotational speed of the engine is smaller than a predetermined value.

Abstract: The invention relates to a plastic film heat seal apparatus which comprises a heat seal bar covered with at least one low adhesive sheet. The heat seal bar is pressed against superposed layers of plastic film so that the layers of plastic film can be heat sealed with each other by the heat seal bar to have a heat sealed portion whenever the layers of plastic film are intermittently fed in a direction and temporarily stopped. The low adhesive sheet is interposed between the heat seal bar and the layers of plastic film for protection of the layers of plastic film when the heat seal bar is pressed against the layers of plastic film. The heat seal bar is then retreated and spaced from the layers of plastic film to permit the layers of plastic film to be fed again after being heat sealed. The heat sealed portion includes upstream and downstream edges in the plastic film feeding direction. The apparatus further comprises loosening means by which the low adhesive sheet is loosened at a position upstream of the heat seal bar in the plastic film feeding direction after the heat seal bar is pressed against the layers of plastic film. The apparatus further comprises holding means by which the low adhesive sheet is held at a position downstream of the heat seal bar in the plastic film feeding direction. Thelow adhesive sheet sheet therefore pulled by and peeled off the layer s of plastic film gradually and progressively in a direction to the upstream edge from the downstream edge of the heat sealed portion when the layers of plastic film are fed again after being heat sealed.

IPC: B65D47/40
Filed: 2002-11-06
Abstract: The improved container for staring and dispensing liquids has a baffle which resists spilling and pours more smoothly than prior containers. The baffle may be located between the mouth opening and the interior of the container chamber. When the improved container is tilted for pouring, such that the liquid level inside the container chamber is higher than the liquid level at the mouth opening, no liquid pours out of the: container. The liquid starts to flow out of the mouth opening only after the container is tilted beyond a predetermined start-to-pour angle. The start-to-pour angle is reached when the container is tilted to allow the outside air to enter the container chamber. The baffled container may have an optional notch on the baffle to reduce glugging and to result in a smoother pour. The improved container can be manufactured in a simple one-step blow molding process.

Title: Equal order method for fluid flow simulation
Inventor: WAITE DAVID MARC
IPC: G06F17/50
Filed: 2001-07-02
Abstract: The present invention provides a method for solving the Navier-Stokes equati on of viscous, incompressible laminar flows with moving free surfaces in comple x domains. The method (100) derives discretized momentum equations using finit e element procedures on a fixed mesh (40). Pressure and velocity of this discretized momentum equation is defined on all the nodes of the mesh (42). The method further provides a discretized continuity equation where velocity  is defined on a Gaussian-point between the nodes of an element (105). Furthe r, the Gaussian-point velocity is a function of the nodal velocity. The discretized momentum and continuity equations are solved to determine the pressure field (106). The velocity field is then determined from the newly determined pressure field. As the velocities and pressure fields are solved for at each nodal point, the accuracy of the solution is preserved. The predicted Gaussian-point velocity field conserves mass to machine round-off levels for element types in which the pressure gradient and velocities can b e evaluated on a consistent basis.
