  • Publication number: 20020073923
    Abstract: A semiconductor water is contained in a reaction tube, and the reaction tube is exhausted through an exhaust pipe while supplying ammonia and dichlorosilane into the reaction tube. A silicon nitride film is deposited on an object to be heat-treated by a reaction of ammonia and dichlorosilane. Subsequently, TEOS is supplied into the reaction tube, while the reaction tube is exhausted through the exhaust pipe. A silicon oxide film is deposited on the object by resolving the TEOS. A semiconductor wafer on which a laminated layer of the silicon nitride film and the silicon oxide film is formed is unloaded from the reaction tube. Then, reactive products attached into the exhaust pipe and the reaction tube are removed, by conducting fluoride hydrogen thereinto, thereby cleaning the pipes. The top end of the exhaust pipe is split into two vents, either one of which is used for discharging exhaust gas for forming films and the other one of which is used for discharging HF gas for cleaning the pipes.

An animal worn device comprising sod and shock producing elements is attached to a leash or lead. A transducer or similar strength measuring means is connected to the shock and sound producers of the animal worn device. The leash or lead is connected to the transducer. As the animal pulls of the lead, the transducer measures the strength of the pull. When the pull strength of the animal reaches a first level, an audio tone is sounded. If the strength of pull exceeds a second level a shock is administered to the animal. In this fashion the animal learns not to pull to hard on a lead. In an alternate embodiment, the trainer has a transmitter with variable signal strength. The animal worn device had a receiver that senses the signal strength. If the signal strength drops to a preset limit indicative of distance from the transmitter, a tone is sounded. Further signal drop results in the a shock being delivered.

    Abstract: Compression brake systems using “back-fill” between combustion cylinders or requiring an exhaust valve to be opened twice during a braking cycle require brake actuation systems able to maintain control over the exhaust valve during different loading conditions. In a first opening event where a piston is at or near bottom dead center, pressures in the combustion cylinder are low. During a second opening event near top dead center pressures are higher. Movement of the exhaust valve may be slowed during the first opening event by controlling fluid leaving a second actuator volume opposite a first actuator volume providing opening force on an exhaust valve.

  • Publication number: 20020073962
    Abstract: Even in such an arrangement in which the throttle valve is operated independently of the engine control system, abnormal engine behavior is ensured to be detected such that a necessary fail-safe operation should be taken. The arrangement of the invention is comprised of the electronically controlled throttle system, engine control system and engine speed monitoring unit, wherein the electronically controlled throttle system is allowed to monitor engine behaviors. Thereby, in the case when the throttle valve is operated independently of the engine control system, if its engine behavior becomes abnormal relative to its drive contents, the engine system senses the abnormality, and takes a fail-safe operation such as to stop operation of the throttle valve and the like.

  • Publication number: 20020073963
    Abstract: Optimum MBT and BDL ignition timing value are obtained from calibration values stored in stability limited (SL) and optimum power (OP) calibration tables using a power index (PI) value that is indicative of the relative desire of the driver for fuel economy or power to interpolate over the range of values in the SL and OP tables to calculate values of MBT and BDL that are optimal for all altitudes and levels of driver demand. The ignition timing value used at any point in time is preferably the lesser of the MBT value and the BDL value. The calibration values for MBT and BDL ignition timing are associated with cam timing values in cam timing tables so that ignition timing changes in lock step with the cam timing.

  • Publication number: 20020073964
    Abstract: A method for knock control of an internal combustion engine, in which values are provided by an adaptive characteristics map for retarding an ignition angle is proposed, the values of the adaptive characteristics map being assigned to at least one operating parameter. Upon occurrence of a dynamic in the at least one operating parameter, a characteristics map value (wkra) is read from the adaptive characteristics map as a function of the instantaneous value of the at least one operating parameter. In this context, a previous value for the ignition angle adjustment (wkr(old)) is only replaced by the characteristics map value (wkra) when the amount of the difference between the previous value for the ignition angle adjustment (wkr(old)) and the characteristics map value (wkra) is less than a predefinable ignition angle difference (KRDWAA) (|wkr(old)−wkra|<KRDWAA).

  • Publication number: 20020073966
    Abstract: A fuel injection system for internal combustion engines essentially comprises a high-pressure injection pump, supplied with fuel from a low-pressure region, and a magnet valve, embodied as a piston valve and serving to control the injection pump, which magnet valve, in a valve housing, has two coaxial valve chambers, communicating with one another through a valve opening but separable from one another by a valve seat, and an armature chamber. The armature chamber communicates with the inlet side via a pressure conduit, and the (low-pressure) valve chamber communicates with the outlet region of the injection pump. The (low-pressure) valve chamber has a fuel inlet conduit and a fuel outlet conduit. The fuel inlet conduit and fuel outlet conduit, each in the respective portions immediately adjacent to the (low-pressure) valve chamber, have a gradually tapered cross section compared to the cross section of the remaining regions of the fuel inlet conduit and fuel outlet conduit.

  • Publication number: 20020073968
    Abstract: The present invention relates to engines having common rail fuel injection systems. In traditional common rail fuel injection systems, each fuel injector utilized by the fuel system includes its own solenoid. These individual solenoids must cooperate to ensure that the proper amount of fuel is being injected from each injector at the proper time. Having individual solenoids requires a multiple number of moving electrical components. In contrast to the traditional common rail fuel injection system, the fuel injection system of the present invention includes fuel injectors that are controlled in operation by a common electronic actuator that is positioned remote from the fuel injectors. Therefore, the present invention reduces the number of moving electrical components in the fuel injection system by reducing the need for individual solenoids for each fuel injector.
