  • Publication number: 20040249804
    Abstract: Facilitating a user determination of an exclusion keyword in order to specify an efficient exclusion of an unwanted piece of data when the user narrows searching objects. Exclusion is accomplished in a system having a searching object data storage for storing pieces of searching object data, a searcher for performing a primary narrowing of the search, a common keyword extractor for extracting the common keywords associated with a piece of data, an input/output device for passing a selected keyword selected the extracted common keywords while receiving and displaying a result from an exclusion efficiency calculator. The exclusion efficiency calculator calculates exclusion efficiency and indicates a level of exclusion efficiency of data that is not associated with a selected keyword for an individual common keyword.

  • Patent number: 6530066
    Abstract: The present invention is to provide a method of computing wiring capacitance to be able to get parasitic capacity depending on the wiring at high speed and with great accuracy, and to provide a method of computing signal propagation delay due to cross talk to be able to remove surplus margins at high speed when delay is predicted. In design of LSIs such as microprocessors or the like, total capacity Ctotal per unit length is determined about each of a plurality of models altering adjacent wiring ((a) no adjacent wiring, (b) one-side adjacent wiring, and (c) both-sides adjacent wiring) and/or crossing ratios ((i) 0%, (ii) 33%, (iii) 67%, and (iv) 100%) and, thereby, a library is formed from these to design the LSI. Regarding characteristic of this total capacity per unit length, the capacity depending on increase of the crossing ratio has a high increase rate in an area of a low crossing ratio, while the capacity depending on increase of the crossing ratio has the low increase rate in high crossing ratio.

For use in the present invention, a fabric may be laminated to at least one side of the metallic hollow panel. The metallic hollow panel is formed into a one-side inflated Roll-Bond panel, a both-side inflated Roll-Bond panel, a both-side flat three-layer Roll-Bond panel or a honeycomb panel. In order to obtain such an automotive sunshade panel of the present invention, the metallic hollow panel is first bent in the roll circumferential direction (Y—Y axis) by means of twin rolls consisting of a rigid roll and an elastic roll, and then is subjected to a flanging process in which its longitudinal edges are flanged by press forming or roll forming.

  • Patent number: 6034912
    Abstract: A memory portion and a logic circuit portion of a semiconductor device are formed on a single semiconductor substrate in which a first logic circuit block and a second logic circuit block are formed in different areas and the second logic circuit is located between a pair of memory blocks. Data stored in the pair of memory blocks are transmitted to the second logic circuit block for processing via a memory peripheral circuit. A result of the data processing is transmitted to the first logic circuit block or an external device via an input/output circuit provided in the second logic circuit block. A clock signal entered at the center portion of the semiconductor chip is supplied to a plurality of first state clock distributing circuits equidistantly disposed from the center portion and then to a plurality of second stage clock distributing circuits at least equidistantly disposed from each of the first state clock distributing circuits.

  • Patent number: 5898636
    Abstract: A semiconductor integrated circuit device having a memory portion and a logic circuit portion formed with a same semiconductor substrate comprising a first logic circuit block, a second logic circuit block disposed in an area different from an area in which the first logic circuit block is disposed, and a pair of memory blocks oppositely disposed so that the second logic circuit block comes in between. Data stored in the pair of memory blocks are transmitted to the second logic circuit block for processing via a memory peripheral circuit provided on the second logic circuit block. A result of the data processing is transmitted to the first logic circuit block or an external device via an input/output circuit provided in the second logic circuit block.
