  • Publication number: 20070106970
    Abstract: An apparatus for supporting a design of a circuit including a plurality of elements, comprising: an acquiring unit that acquires a clock tree of the circuit; a constructing unit that constructs, based on the clock tree, a plurality of groups each of which includes a part of elements of same skew; an analyzing unit that performs an analysis of a timing of an inter-group path between two of the groups; and an output unit that outputs a result of the analysis.

  • Publication number: 20060114641
    Abstract: Provided is a multilayer ceramic capacitor having a capacitor body formed by alternately laminating a dielectric layer and an internal electrode layer, and an external electrode formed on both ends of the capacitor body. The dielectric layer has at least two type of barium titanate crystal grains that differ from one another in at least one selected from Ca composition concentration, Sr composition concentration, and Zr composition concentration, and a grain boundary phase. If this multilayer ceramic capacitor employs, as a dielectric layer, a dielectric ceramic that contains barium titanate crystal grains in which part of Ba is substituted by Ca, Sr, or Zr, it is capable of suppressing the grain growth of crystal grains, and improving relative dielectric constant, temperature characteristic, and high-temperature load test characteristic, for example, in high-volume manufacturing using a tunnel type large kiln.

  • Publication number: 20050153576
    Abstract: Manufacturing is carried out while including the steps of: from a trunk line 12, drawing out electric wires 13a to be a branch line 14 longer than a required length of the branch line 14; forming a branch line portion 17 by applying tape winding to the drawn-out electric wires 13a; making, as a trunk line accompanying part 17a, a part from a base end P2 to a branching position P1 of the branch line portion 17 accompany the trunk line 12 and making, as a main branch line part 17b, a part from the branching position P1 to a front end P3 of the branch line portion 17 distant from the branch line 12; and applying an protecting treatment 19 by tape winding to the whole.
