Patent DE-19924274-A1 (DE)
Title: Turbocharger control system for use in an internal combustion engine e.g. in a motor vehicle
Inventor: LEWIS JUN SPENCER C
IPC: F02B37/18
Filed: 1999-05-27
Abstract: The system has a combustion manager that determines a desired air mass rate based on a current engine operating point and an air system manager (120) determines an air mass rate error as a difference between the desired and actual air mass rates to the engine. A turbo manager (130) controls the operation of the turbocharger to minimize the air mass rate error while maintaining shaft speeds and temperature below predetermined limits. The combustion manager determines a target air/fuel ratio based upon the current operating point of the engine and a mass fuel rate of the engine and then determines the desired air mass rte as the mass fuel rate multiplied by the target air/fuel ratio. The system also includes a waste-gate that is operated to prevent the turbocharger shaft speed exceeding a predetermined limit, with the turbo manager acting to derate the fueling command to the engine if the waste-gate is fully open and the turbocharger shaft speed is still in excess of the predetermined limit. The turbo manager also prevents the temperature of turbocharger from exceeding a predetermined limit by reducing the waste gate bypass amount unless this causes the turbocharger shaft speed to exceed a second predetermined limit. An Independent claim is also included for a method for controlling a turbocharger supplying air to an internal combustion engine.

IPC: B23K26/70
Filed: 1999-08-06
Abstract: Disclosed is a device for treating a substrate with laser radiation, wherein the incoming laser rays can be directed in such a way as to form various outgoing beams. The inventive device is equipped with a rotating polygon mirror with N reflecting surfaces which are used to direct a laser beam which is emitted from a laser beam source via a system composed of converging focusing lenses which are interposed against each other, whereby the focal planes of the lenses are located on the surface of the substrate to be treated. The invention is characterized in that active reflecting surfaces (S) are provided in order to direct the incoming laser beam onto the converging lens system, and subsequently onto the substrate, while the remaining reflecting surfaces (S') have a different inclination to the reflecting surfaces in relation to the converging lens system; the laser beam from said surfaces are directed onto an absorber. The large number of inactive reflecting surfaces helps to reduce serial hole density in said substrate in a substantial manner. When the laser is switched on and off while the inactive reflecting surfaces are being scanned, further reduction of serial hole density can be achieved.
