    摘要: A real-time processor includes a clock register updating a time at a predetermined interval, a time register storing an arbitrary time, a time comparator comparing the time in the clock register with the time stored in the time register, and an instruction processing unit executing an instruction whose execution status is altered according to the comparison result of the time comparator. A predetermined operation can be carried out correctly at a predetermined time since the instruction processing unit executes an instruction whose execution status is altered according to the comparison result of the time comparator.

    摘要: For integrally bonding a first member and a second member made of copper or a copper alloy by brazing, a paste brazing material composed essentially of copper (Cu), tin (Sn), nickel (Ni) and phosphorus (P) is beforehand applied to at least one of the first and second members. A base material is exposed at the whole or a part of a contact portion between the first and second members. Thereafter, the first and second members are assembled at a predetermined position, and heated at a temperature in a range of 600° C.-800° C. within a reducing atmosphere furnace. By the brazing method, an oxide film on the surface of the base material can be sufficiently removed, so that the paste brazing material can smoothly flow on the surface at the contact portion.

    摘要: A motion vector estimating system prepares a predetermined range of a frame/field of image data as a macro block, selects a plurality of proposed motion vectors in the reference region, calculates a signal-strength difference between pixels corresponding to each of the proposed motion vectors of current and reference images. The system comprises: an accumulating element for deriving an accumulation result in parallel on the basis of the signal-strength difference by means of accumulating circuits connected in parallel as a pipeline; an accumulation stopping element having separate stop circuits for separately stopping the accumulation of the accumulating element every n accumulating circuits; and a control element for controlling the supply of the current image data and the reference image data for proposed motion vectors for each of the accumulating circuits, and for outputting a separate stop signal to the accumulation stopping element for stopping the accumulation for the proposed motion vector of the accumulating circuits immediately after the accumulated value of the absolute values of the differences between the signal values of picture elements of the current image and the reference image exceeds a predetermined value. Thus, it is possible to suitably omit unnecessary accumulation in a pipeline processing for estimating a motion vector, so that it is possible to increase the processing speed and to decrease the electric power consumption.
