  • Patent number: 6269066
    Abstract: A composite interferometer and electro-optical prism provide a means to control the position of a spot of light to read and write data on an optical disc. In this invention each light ray from a spectral source of a cone of light rays is regenerated into a plurality of light rays by an interferometer. These rays are transmitted through an electro-optic crystal and focused by a lens into a constructive interference fringe on an optical disc. A voltage across the electro-optical crystal and magnetic field inside the spectral source define the position of the constructive interference fringe on the disc.

  • Patent number: 6213088
    Abstract: The invention relates to a method for improving the thorough mixing of the exhaust gas/fuel mixture in an internal combustion engine (1), whereby the exhaust gas stream is at least temporarily impinged upon by an increased exhaust-gas mass flow when additional fuel is supplied. According to said method, during the exhaust stroke, when the exhaust valve (8) or exhaust valves are open, the additional fuel is fed directly into the combustion chamber of the internal combustion engine (1). The invention also provides for a device to carry out said method, according to which the additional fuel is injected during the exhaust stroke when the exhaust valve (8) or exhaust valves (8) are open by means of at least one injection nozzle (10) positioned in the combustion chamber. Both the method and the device are especially simple and cost-efficient.

  • Patent number: 6189396
    Abstract: The invention concerns a control arrangement for an automatic electrohydraulically controlled transmission. In order to reduce expenditure on parts and assembly, the hydraulic control system and electronic control system are mounted directly adjacent each other and plug-in connections are provided between the solenoid valves of the hydraulic control system and the electronic control system. The hydraulic control system (20) substantially comprises two duct panels (28,30) in which control ducts, piston slides and solenoid valves (not shown) are disposed for controlling the conical plates and couplings of the transmission. The pressurized hydraulic fluid is fed directly into these duct panels from the pump (29). The electronic control system (22) has a single central connection (36) which is secured in the transmission housing cover (42) by an annular seal. Rotational speed sensors for the transmission shafts and temperature and pressure sensors are integrated into the control unit.
