  • Pattern data processing system, pattern data processing method, and pattern data processing program
    Patent number: 7907771
    Abstract: A pattern data processing method comprising, obtaining pattern data on a mask pattern, determining whether a processing time for the mask pattern in a processing software is reduced by rotating the mask pattern by a predetermined angle than a case where the mask pattern is processed in the processing software without being rotated, obtaining pattern data on a rotated pattern formed by rotating the mask pattern by the predetermined angle in the case that the processing time is reduced, processing the pattern data on the rotated pattern by using the processing software, and causing the mask pattern to return to its original direction.
    Type: Grant

  • Foldable seat structures for automobiles
    Patent number: 4194782
    Abstract: Disclosed is an automobile having front and rear seat structures, the rear seat structure comprising forward and rearward rows of folding seats. The forward and rearward rows of seats of the rear seat structure are interconnected in such a manner that the rearward row can be moved towards the forward row, and then both the forward and rearward rows can be moved towards the front seat structure to provide a substantially unobstructed space behind the folded rows of seats.
