    Abstract: PURPOSE:To allow the later mentioned logical simulator to realize an expected value collating function by adding a comparator to a circuit to be simulated and correcting the circuit as the preprocessing of the logical simulator having no expected value collating function. CONSTITUTION:A comparator storing means is constituted of a comparing element 11, a comparing input terminal group (CI1, CI2) 9 and a comparing output terminal group (CO1, CO2) 10 to compare the inputs CI1, CI2 of four values 0, 1, X, Z, with each other and output 16 kinds of output values to four output terminals CO1-CO4 in the group 10. A circuit converting means add is a comparing element for the comparator storing means and an expected value input terminal to each terminal in an external output terminal group of an internal circuit of an objective circuit storing means to convert the circuit into a simulation circuit 4. The logical simulator compares an output appearing from the external output terminal group with an expected value and outputs a collated result from a collated result output terminal group 15 as hexadecimal value.

    Abstract: PURPOSE:To improve the wiring processing efficiency of a printed board containing different parts by setting different lattice systems in response to those parts having different spaces among terminal positions and referring to a table showing the corresponding relations among those lattice systems. CONSTITUTION:The wiring area of a printed board 11 is divided into a reference area A0 and internal areas A1 and A2, and an inter-area corresponding relation table is stored to show the spaces between lattice and addresses of reference points corresponding to each other in terms of the coordinate value of the reference point of each area and the lattice point information. Then the data are stored in the form of the lattice point information to check whether the coordinate value of each lattice point and each lattice point can be wired or not and whether the searching direction and each lattice point are equal to those points on the boundary between areas or not for each of those areas A0-A2. Then a wiring route is searched and wired within a single area and it is checked whether this route reaches a target point or not. The processing is finished when said wiring route reaches its target point. While it is decided whether the wiring route reaches the area boundary or not if the route does not reach the target point yet. If so, the grating transfer processing is carried out.

    Abstract: PURPOSE:To obtain the titled material with absorption characteristics stable to temperature variation, usable in high-frequency zone, by incorporating a polymeric resin with transition metal element-contg. fibrous noncrystalline alloy or either granular or foil-shaped transition metal element (such as iron or nickel)-contg. noncrystalline alloy. CONSTITUTION:The objective material can be obtained by incorporating (A) a polymeric resin 1 with (B) transition metal element (such as iron or nickel)- contg. fibrous noncrystalline alloy 2. For such ratio absorbing material as to be effective for both electric and magnetic field components of electromagnetic wave, at least one kind of granular or foil-shaped noncrystalline alloy 3 containing crystalline transition metal element such as iron or nickel is preferably dispersed.
