IPC: H01B7/06
Filed: 1988-03-01
Abstract: PURPOSE:To make it possible to skip backturn and reprocessing of curl set once curl set is processed and to aim at improvement of elasticity and curl retention of curl cord, by forming sheath layer with two kinds of elastic resin materials which have different contraction coefficients at molding from each other, divided in two parts along the longitudinal direction and combined in one body. CONSTITUTION:The element of sheath layer 3 of a curl cord is supported to be divided longitudinally and integrally composed of two kinds of elastic resin materials 3a, 3b which have different contraction coefficient at molding from each other. Curl set is processed, while holding the resin material 3a (or 3b) with a contraction coefficients larger than the other one toward inner surface. A helix diameter at molding is determined by taking the difference in contraction coefficients of the two resin materials 3a, 3b into account. As a result, the curl cord processed with curl set is naturally given its potential to hold the helix from generated by the difference in contraction coefficients of the resin materials 3a and 3b both of which constitute the sheath layer 3. The curl will not get loose even after backturn of the curl cord once curl set is processed and therefore, no reprocessing of curl set is required at all.

Abstract: PURPOSE:To set always the average DC potential to the earth level to prevent click sound, by using a saw tooth wave or a triangular wave as the input signal and by varying the duty ratio of the output square wave by the modulation signal. CONSTITUTION:Saw tooth wave Vin 11 is input to comparator CMPA11, and voltages VD1 and VS1 are varied by modulation signal Vref 12 connected in parallel to DC power sources A12 and A13 which supply positive and negative DC voltages VD1 and VS1 of CMPA11. Therefore, the threshold voltage is always 1/2(VD1+VS1) for voltages VD1 and VS1, which determine the output crest value, and is variable for the earth level to vary the pulse width of the output square wave. Simultaneously, positive and negative crest values of output signal Vout 13 is caused to be proportional to voltages VD1 and VS1 by voltages VD1 and VS1, and control is so performed that the average value DC potential of the output square wave which has the pulse width modulated may be always the earth level.

Abstract: PURPOSE:To easily obtain intersection coordinates from the apex coordinates of a square based on a table by preparing the table of the overlapping of the two squares. CONSTITUTION:In the square extracted in a maximum square moving system, one square in the array of maximum squares inscribed with a graphic is set at S, and the next square is set at S'. The reference points of S and S' are set at P and P', and the inverse of P and the inverse of P', and an area is divided into nine parts with S as a center. The combinations of the two intersections of the square are those of P'/the inverse of P' in the divided area of P/the inverse of P, and twelve combinations are cited. Based on the twelve combinations and the position relation of the intersections, coordinate values X and Y are rearranged in a table. The overlapped intersections Q1 and Q2 of S and S' are set at the intersections obtained by clockwise tracing Sm, and they can be obtained from the table. An intersecting side is automatically traced from a start point, the intersection or the apex is confirmed, finally the trace is returned to the start point, and thus a contour can be extracted. In such a way, since the intersection of the two overlapping squares can be easily extracted from the table of the overlapping combinations, the complicated calculating processing is made unnecessary, and a high speed processing is attained.
