A wiring pattern is divided into sets of long wiring (L1) and sets of short wiring (Ls) by comparison to a reference value. Layout rules of the sets of long wiring (L1) are made different from layout rules of the sets of short wiring (Ls) by using an effect of a Levenson type phase shift. Thereby, an interval (S ) between a set of long wiring (L1) and a set of short wiring (Ls) is made relatively narrower than an interval (S ) between a set of long wiring (L1) and a set of long wiring (L1).

Method of manufacturing semiconductor integrated circuit device

This invention relates to a control method for a remote supervisory control system which includes a single master station and N (plural) remote stations sporadically lying in distant places, said method used for supervising and controlling the states of the N remote stations by the single master station. Since the method is of the type in which the one master station supervises and controls the states of the N remote stations, it is also termed the 1-to-N remote supervisory control method. The master station supervises the remote stations by indicating, for example, the 'on' and 'off' states of circuit breakers on the basis of signals from the remote stations, and controls the states of the remote stations by transmitting 'off' and 'on' control signals conversely from the master station to the remote stations.

Control method for a remote supervisory control system

A signal checking system for use in a hardware system having a converter for converting coded input signals consisting of a plurality of bits into corresponding individual signals, wherein undesirable selection of an erroneous output and multiple outputs by the converter is detected by means adapted for checking the relation between the input to the converter and the output of a first coder connected to the converter and checking the complementary relation between the output of the first coder and the output of a second coder connected to the converter.
