摘要:
The invention relates to a cyanide-free electrolyte being harmless to the environment and to health which makes feasible the production of black surface layers on light metals or on alloys of the latter, preferably titanium, remaining deeply-black and adhesive even after extreme changes in the ambient temperature and having nearly equal values of the optical absorptivity of radiation and of the thermal emission capability (the .alpha./.epsilon.-ratio is about 0.95) by means of the anodic oxidation by spark discharge (ANOF-method). These layers are absolutely X-amorphous and show, hence, an ideal optically isotropic behavior regarding the reflection of radiation. Due to their minimum evolution of gases they offer a high thermovacuum stability. The electrolyte consists of an ammoniacal solution of K.sub.2 H.sub.2 PO.sub.4 potssium dihydrogenphosphate and K.sub.2 CRO.sub.4 potassium chromate. The homogeneity of the optically black layers is ensured by not using fluoride ions and employing acetate ions. Such layers comprise titanium, chromium and copper following ratios of CR:Ti=1:(1.9 to 2.2) and CR:Cu=1:(0.8 to 1.3).

A fitting (1) for an adjustment device, in particular inclination adjustment of a motor vehicle seat, includes a fitting upper part (2) having a first internal toothing (4), a fitting lower part (3) which is adjustable relative to the fitting upper part about a fitting axis and has a second internal toothing (5) arranged coaxially with respect to the first internal toothing, at least two, preferably, three, rotatably arranged planet gears (7) which are in engagement with the first and second internal toothings, and a drive shaft (6) which is in operative connection with the at least two planet gears by means of a pinion (23). Noise loads and buckling effects are avoided even after a relatively long period of operation, with a spring element (11) prestressing the planet gears (7) in the direction of the axis of rotation onto the fitting lower part (3) or fitting upper part (2).

Systems and methods of user interface for facilitation of high level generation of processor extensions. In accordance with a method embodiment of the present invention, an instruction format is accessed at a graphical user interface. A programming language description of a computation element for an execution unit of the processor extension is accessed. A representation of a hardware design for the processor extension comprising the instruction format and the computation element is generated.

A method of automatically extracting information from an architecture description. A memory resident directed acyclic graph data structure comprising nodes representing instructions and edges whose weights represent dependencies between pairs of instructions is constructed. A list of ready nodes are maintained in the directed acyclic graph. A list of nodes not scheduled is maintained. And, it is determined whether the next instruction to be scheduled is to be taken from the list of ready nodes or from the list of nodes not yet scheduled.
摘要:
A method of simulating a program. Compiled and interpretive techniques are combined into a just-in-time cached compiled technique. When an instruction of a program simulation is to be executed at run-time, a table of compiled instructions is accessed to determine whether compiled data for the instruction is stored in the table. If the compiled data is not therein, the instruction is compiled and stored in the table. The compiled data is returned to a simulator that is executing the program simulation. In another embodiment, before storing new information in the table, another table may be consulted to determine if the location to which the new information is to be stored is protected. If the table location is protected, the new information is not stored in the table. Rather, the new information is simply passed on to the simulator.

A method and system for marking a location with a mobile device, uploading location information from the marked location to a location based service, creating a web page for the location information, and adding descriptive content to the web page pertaining to the location.
摘要:
A shaped part or article of manufacture is formed of a selected gamma titanium aluminide alloy with outstanding mechanical properties which can be produced particularly economically. First, a semi-finished article is formed in a hot forming process with a degree of deformation of greater than 65%. Then the semi-finished article is shaped with the alloy being in a solid-liquid phase by applying mechanical forming forces during at least part of the shaping process.
摘要:
A sunroof, for a motor vehicle having a roof opening, includes a roof frame locatable in the roof opening for defining the perimeter of the roof opening and at least one panel fitting within the roof frame arranged to close the roof opening. The panel is hingedly mounted to the roof frame at a forward panel edge so that the panel can pivot about the hinged mounting so as to rise at a rear panel edge to open the sunroof. A positioning device is arranged adjacent the rear panel edge to hold the panel open. The positioning device includes at least an upper link and a lower link connected pivotally together at a knee joint which is movable with respect to the roof frame, with the upper link being connected to the panel at the end of the panel opposite the knee joint and the lower link being connected to the roof frame. A clamp is arranged at the knee joint to lock the knee joint. The knee joint being such that the links form at least a part of a lamella pack construction where adjacent lamellae interact frictionally under compressive forces produced by the clamp to lock the knee joint.
摘要:
Generating a description of compiler code selector rules from an architecture description. A method comprises accessing a target architecture model written in an architecture description language (ADL) and extracting semantic information therefrom to generate a plurality of semantic statements. Rules that map from source code operations to semantic patterns are accessed. The semantic statements are searched for matches for the semantic patterns to generate mappings that serve as a description of compiler code selector rules.
摘要:
A seat fitting for a motor vehicle seat, with a fitting lower part which is connectable to a seat lower part, a fitting upper part which is connectable to a seat back, an eccentric epicyclic gearing which connects the fitting upper part and fitting lower part in an articulated manner and is intended for adjusting the inclination of the fitting upper part in relation to the fitting lower part, and an actuating mechanism for coupling the seat fitting to a seat longitudinal guide. The fitting upper part has a pivoting body. The actuating mechanism is formed by an unlocking lever. The pivoting body substantially completely shifts the unlocking lever into the unlocking position irrespective of the inclination to which the fitting upper part is set.
