Abstract: A data processing device (500) contains an execution circuit (200) and a data buffer circuit (210, 213). The above data buffer circuit (210, 213) stores one or more commands and/or one or more parameters which are prefetched, until each of the commands and parameters is read out by the above execution circuit (200). The above execution circuit (200) inputs a command which is the oldest one of the commands stored in the data buffer circuit (210, 213) when an execution of a preceding command is completed, inputs one or more parameters stored in the data buffer circuit (210, 213) when the command input therein requests the parameters, and executes the command input therein, using the parameters when the parameters are input therein. The above data processing device (500) further contains an insufficient space detecting circuit (60, 80, 231 - 235, 237, 238, 239) for detecting a first state of the data buffer circuit (210, 213) in which state there is not enough vacant space in the data buffer circuit (210, 213) in which a further command and/or a parameter can be stored, and a least data detecting circuit (60, 80, 235, 236, 238) for detecting a second state of the data buffer circuit (210, 213) in which state the data buffer circuit (210, 213) does not store data including a command and/or a parameter, which is necessary for a next operation in the above execution circuit (200). A prefetch control circuit (100), provided in either in the device (500) or outside of the device, starts the prefetch operation and continues successive prefetch operations when the second state is detected, and stops the prefetch operation when the first state is detected. The system using the above device (500) contains a memory (502) which stores the above commands and   parameters in the order of execution in the execution circuit (200).

Abstract: A method and apparatus are disclosed for controlling a vehicle steering system of the type having front steerable wheels (14,16) and rear steerable wheels (42, 44). The present invention permits the vehicle operator to select front wheel only steering, crab steering, or curl steering. If the vehicle speed is above a predetermined value, steering control is automatically switched to front wheel only steering, and the rear steerable wheels are locked in the straight-­ahead direction. The lock mechanism (58) is not actuatable until the rear steerable wheels are sensed to be within a predetermined angle of a straight-­ahead direction. If the vehicle operator switches from one steering mode to another steering mode, the rear steerable wheels must return to a near straight-­ahead direction before the mode will be switched. When the vehicle wheels are locked in front wheel only steering and the lock mechanism is deactuated so as to unlock the rear wheels from the vehicle frame (27) but the rear wheels do not unlock, the present invention applies alternately driving forces to the rear steerable wheels so as to dither the wheels and free the locking mechanism. A lock mechanism is also disclosed.

Abstract: The disclosed method can produce high T c  superconductor material e.g., YBa₂Cu₃O₇) of substantially increased intra-grain critical current density (J           '       c             ) as compared to conventionally produced bulk material of analogous composition. Exemplarily, YBa₂CU₃O₇ pellets produced according to the invention had J           '       c              of about 10⁵A/cm² at 77K in an applied magnetic field of 0.9 Tesla. The inventive method comprises providing a precursor material whose composition differs from that of the desired superconductor with respect to at least one of the metal constituents of the desired superconductor. It further comprises heating the precursor material above the decomposition temperature (T d ) of the precursor material such that a multiphase material results. The multiphase material comprises, in addition to a majority first phase, a dispersed precipitate phase. The method further comprises cooling the multiphase material to a temperature below T d  at a rate such that at least a major portion of the precipitate phase is retained. The first phase differs from the desired superconductor at most with regard to oxygen content, and the heat treatment of the multiphase material is carried out such that the desired superconductor results. Exemplarily, the desired superconductor is YBa₂CU₃O₇,the precursor material has average composition YBa₂Cu₄O z (z∼8), the precipitate phase comprises one or more copper oxides, T d  is about 860°C, and the multiphase material is produced at 920°C.
