Publication number: 20010009147Abstract: In an electronic control for a hybrid vehicle which is driven either by an engine or an electric motor, or both, possible failures in an ignition system and a rotation sensor system are detected during a period in which the engine is rotated by the motor with no fuel supply. Only after no failure is found, the engine is started by supplying fuel and performing ignition. Thus, the fuel supplied to the engine is ignited without fail, and unburned gas release to the atmosphere is surely prevented. Also, good drivability is maintained. In case the invention is applied to a series hybrid vehicle which is driven solely by an electric motor powered by a battery which is charged by an electric generator driven by an engine, the ignition system is diagnosed when the engine is not rotating. After it is determined that there is no failure in the ignition system, the engine is started.Type: ApplicationFiled: February 22, 2001Publication date: July 26, 2001Applicant: DENSO CORPORATIONInventors: Hiroyuki Takashima, Shigehito Kimura

Publication number: 20010009149Abstract: A pump control means controls a fuel pump so that fuel pressure supplied into the internal combustion engine becomes lower than a predetermined fuel pressure regulated by a fuel pressure regulator when the operating state of the internal combustion engine is within a predetermined operating state. Thus, the fuel pressure has already been controlled low while the engine state is within the predetermined operating state, so that the fuel leak from the injector during an engine stop is suppressed, thereby reducing an exhaust of deleterious gas when the engine starts again. Further, since the fuel pressure is decreased while the engine works, electric power is not wasted for decreasing the fuel pressure.Type: ApplicationFiled: January 23, 2001Publication date: July 26, 2001Inventors: Yasuo Hirata, Hidehiko Asama

Publication number: 20010009150Abstract: The fluid displacement pump enables substantially continuous pumping from a low-pressure side to a high-pressure side substantially without any backflow or backpressure pulsations. Liquid or gas is injected to the high-pressure side by way of mutually intertwined worm spindles that form a fluidtight displacement system. The blades of the impeller system are almost flat, i.e., their attack angle relative to backpressure is close to perpendicular so that they will turn quite freely in the forward direction, but will not be turned backwards by a pressurized backflow. The impeller rotation that is introduced via the spindle shafts nevertheless leads to a volume displacement towards the high-pressure side, for instance, towards a chamber to be pressurized or to be subjected to equal pressure. The impeller system can be driven with variable speed, which translates proportionally in a variable pressure buildup.Type: ApplicationFiled: February 9, 2001Publication date: July 26, 2001Inventor: Arthur Vanmoor

Publication number: 20010009183Abstract: A control system and method for controlling a low-pressure die casting machine wherein the pressure within the dies more accurately tracks the desired recipe pressure. The control system senses pressure in the dies and compares the sensed pressure to desired pressure. Should the difference between the sensed pressure and the desired pressure be indicative of a problem in the casting operation, subsequent casting cycles are prevented. Should the difference between the sensed pressure and the desired pressure by indicative of a potential catastrophic failure, the current casting cycle is immediately terminated, thereby minimizing the possibility of catastrophic failure. The control system has commercially available and easily replaceable components and, thus, can be quickly repaired to reduce machine downtime should any component fail.Type: ApplicationFiled: March 14, 2001Publication date: July 26, 2001Inventor: Richard D.

Publication number: 20010009189Abstract: A well has a vertical casing with a window, and a lateral wellbore which communicates with the window, and which may have a casing or liner. A window assembly aligned with the window has respective passageways for first and second tubing strings, and has a concave surface for deflecting the first tubing string out into the lateral wellbore. The passageway for the second tubing string has a portion which is inclined at a very small angle with respect to a vertical centerline of the vertical casing. As the first tubing string is run into the vertical casing, a rotational locator is releasably coupled thereto by a soft release coupling mechanism. After the locator effects rotational orientation, the coupling mechanism is released and then permits the first tubing string to move therepast without damage. A seal assembly on the first tubing string is covered by a protective sleeve as it is inserted into the well, and exits the protective sleeve after entering the lateral wellbore.Type: ApplicationFiled: January 19, 2001Publication date: July 26, 2001Applicant: Dresser Industries, Inc.Inventors: Robert T.
