    摘要: A cooling jacket casting core for the production of a cylinder head of an internal combustion engine. The cooling jacket casting core has a slot running at least in part substantially in the direction of a crankshaft longitudinal axis and separating the cooling jacket casting core in at least one section. The slot can run at least in part in an impression of the cooling jacket and can have at least one elevation arranged perpendicular to the longitudinal axis of the cooling jacket casting core.

    摘要: A cooling jacket casting core according to the invention for the production of a cylinder head of an internal combustion engine comprises at least one impression of a cooling jacket. The cooling jacket casting core itself has a slot running at least in part substantially in the direction of a crankshaft longitudinal axis and separating the cooling jacket casting core in at least one section. In accordance with a further development, the slot runs at least in part in the impression of the cooling jacket. The slot preferably has at least approximately one elevation arranged perpendicular to the longitudinal axis of the cooling jacket casting core. This longitudinal extension of the slot runs parallel to a crankshaft associated with the cylinder head in an internal combustion engine.

    摘要: An optical duplexer, configured as a directional coupler, is integrated into an optical coupling arrangement with a fiber optic pigtail, constructed in planar-optical hybrid technology on a substrate (1). To reduce the required surface area and decrease optical cross talk, the branch of the directional coupler (waveguide 6, branch 7) is sharply bent. The bend is equipped with a reflecting mirror (11) integrated opposite the inner edge (10) of the bend. Furthermore, the waveguiding end of the bent branch (7) is equipped with a cylindrical lens. A laser diode (8) is located before this, and a photodiode (5) is located before the angled end of the straight-line integrated waveguide (2).

    摘要: An interferometric semiconductor laser includes a cavity in the form of a Y and at east three individually actuatable active segments. A central segment couples together the individually actuatable active segments. The central segment is an active or passive segment that acts as a beam divider. The arrangement of the segments forms two resonator paths which contain at least one common active segment. At least one resonator path includes an active segment that does not belong to the other resonator path. In the absence of, or with the same actuation of the active segments, the optical path length of one resonator path differs from the optical path length of the other resonator path.
