摘要:
A monolithically integrated laser diode chip having a construction as a multiple beam laser diode, which, on a semiconductor substrate (3) comprised of GaAs, has at least two laser stacks (4a, 4b, 4c) which are arranged one above another and which each contain an active zone (7). The active zone (7) is in each case arranged between waveguide layers (8). The waveguide layers (8) each adjoin a cladding layer (6) at a side remote from the active zone. At least one of the waveguide layers (8) or cladding layers (6) of at least one laser stack (4a, 4b, 4c), comprises AlxGa1-xAs, where 0≦x≦1, and at least one additional material from main group III or V, such that the lattice mismatch between the at least one waveguide layer (8) or cladding layer (6) comprising the at least one additional element and the semiconductor substrate (3) composed of GaAs is reduced. This increases the lifetime of the laser diode chip.

The invention relates to a method and device for the continuous polycondensation of polyester material in the solid phase, in particular in the form of partially crystalline granulate. The aim of the invention is to achieve a high product throughput on recrystallising and recondensation of polyester material with a low initial IV. Said aim is achieved, whereby on recrystallisation, a low residence time of 1-10 minutes is achieved, by means of a rapid heating of a thin product layer, followed by an SSP treatment.
摘要:
A real-time system for modeling a turbo-charged engine includes a model configured to estimate various exhaust states such as turbine inlet pressure, turbine outlet pressure, turbine outlet temperature, turbine mass flow rate and waste-gate valve mass flow rate. The model is dependent only on the availability of normal operating values available in a conventionally-configured automotive controller and one or more measured intake side parameters such as ambient pressure, boost pressure, ambient temperature and compressor mass flow rate. The model is constructed to reflect a high-level application of energy conservation between the turbine (generated power) and compressor (absorbed power). A method for the indirect measurement of turbine and waste-gate flow uses turbine inlet and outlet pressure, inlet temperature and engine mass air flow rate measurements. A method for the indirect measurement of turbine efficiency avoids the need for manufacturer's turbine data.

摘要:
An electric device comprising a plurality of operating elements which can be operated by a user. Said device is associated with a status display device, and it also comprises a control logic unit which is coupled to the operating elements in order to detect user operations and which is adjusted. Furthermore, the electric device has an operational state which corresponds to the user operations which are to be adjusted. In a first state, the control logic unit displaces the status display of each operational element, from which it is able to process a user operation, according to an adjusted operational state, and in a second state, said unit displaces the status display of each operational element, whereby it is not possible to process a user operation, according to an adjusted operational state.

The present invention relates to a method of producing coloured carrier particles (substrates), which comprises a) dispersing the carrier particles in a solution of a colorant or latent pigment, adding the carrier particles to a solution of a colorant or latent pigment, or adding a latent pigment or a colorant to a dispersion of the carrier particles, b) precipitating the colorant or latent pigment onto the carrier particles, and c) in the case of a latent pigment, subsequently converting it to the pigment, and to the coloured substrates obtainable by such a method, and also to the use thereof. Using the methods according to the invention it is possible to obtain colorations and coloured substrates that have surprisingly good light-fastness properties.
