    • 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.

    • A centering device (1) for flat workpieces, especially sheet-metal blanks to be processed in a press, comprises a first table (100.1), which can be rotated about a first vertical axis (90), for receiving a workpiece and a second table (100.2), which can be rotated about a second vertical axis (90), for receiving a workpiece. The second table (100.2) is arranged to the side of the first table (100.1), and a support level of the first table (100.1) coincides substantially with a support level of the second table (100.2). The device furthermore comprises a rotation mechanism (45, 46, 50, 61), which is coupled mechanically to the first table (100.1) and to the second table (100.2) in such a way that the first and the second tables (100.1, 100.2) can be rotated jointly about a third vertical axis (50). If both tables (100.1, 100.2) are rotated jointly about the third vertical axis (50), the tables (100.1, 100.2) form a common supporting surface. In the other operating mode, the tables are rotated individually about the spaced vertical axes of rotation (90); the tables and their supporting surfaces thus move relative to one another. With the device according to the invention, it is thus possible without conversion work to correctly orient either an individual workpiece, which can take up the entire width of the centering device (1), or two narrower workpieces at the same time for subsequent processing.

    • A system and method for controlling a compressor recirculation valve involves establishing a compressor surge flow threshold expressed in terms of a compressor corrected volume air flow rate. A torque-based engine management system computes a desired mass air flow rate in accordance with a torque request and other operating/predetermined data. The desired mass air flow rate is converted into a desired, corrected volume air flow rate, which is then compared to the compressor surge flow threshold. The controller is configured to open the valve when the desired corrected volume air flow rate is less than the compressor surge flow threshold. A hysteresis function is implemented by providing a surge flow hysteresis threshold that is offset from and greater than the initial compressor surge flow threshold. The controller is configured to close the recirculation valve when the desired corrected volume air flow rate becomes greater than the surge flow hysteresis threshold.
    • 用于控制压缩机再循环阀的系统和方法涉及建立以压缩机校正的体积空气流量表示的压缩机喘振流量阈值。 基于扭矩的发动机管理系统根据转矩请求和其他操作/预定数据来计算期望的质量空气流量。 将期望的质量空气流量转换成期望的校正体积空气流量,然后将其与压缩机喘振流量阈值进行比较。 控制器被配置为当所需校正的体积空气流量小于压缩机喘振流量阈值时打开阀。 通过提供与初始压缩机喘振流量阈值偏移并且大于初始压缩机喘振流量阈值的浪涌流滞后阈值来实现滞后功能。 当所需的校正体积空气流量变得大于浪涌流滞后阈值时,控制器构造成关闭再循环阀。
