  • Patent number: 7032198
    Abstract: A method for designing an integrated circuit such as a VLSI circuit, in particular optimizing delay of a signal transmitting through signal lines connecting a signal supplying source to each of elements, whereby skew can be decreased. The method can include determining whether the signal source satisfies a fan-out restriction if the signal source supplies a signal to all of the driven elements which are directly connected to the signal source, dividing the elements into groups so that the fan-out restriction is satisfied in each of the groups and each of the groups has the same or substantially same load capacity, when the signal source does not satisfy the fan-out restriction, and inserting into each group, a buffer having a size which makes the groups of elements satisfy the fan-out restriction. The dividing and the buffer inserting are repeated until a positive determination is delivered on the fan-out restriction.

  • Publication number: 20050233145
    Abstract: A heat-accumulative material which is a polymer or oligomer having, as a main constituent component, units having a polyether main chain and a side chain, side chains capable of being crystallized, and heat-accumulative composition comprising the same heat-accumulative material. The heat-accumulative material tends to be kept at a constant temperature more effectively by absorbing heat as ambient temperature increases to melt, and releasing heat as ambient temperature decreases to solidify, to moderate changes in ambient temperature, and thereby to exhibit the function as a heat-accumulative material. They have a sufficiently high viscosity, preventing the heat-accumulative material from flowing out even when it is molten. Each of the heat-accumulative material and composition can be made into a heat-accumulative film or sheet, laminate, molded article, composite fiber and cloth which can be suitably used around a body.
