IPC: B41J31/02
Filed: 1985-05-07
Abstract: PURPOSE:To omit the step of drawing an extremely narrow borderline by using a water repellent and enhance productivity and operation efficiency, by a method wherein when weaving a cylindrical body, extremely narrow bands are provided at predetermined intervals by using yarns spun from heat-fusible fibers, and the bands are converted into films by heating to provide borderline. CONSTITUTION:A loop is formed by reciprocating a single weft two times, and the weft is spirally moved to sequentially form a cylindrical form 1, to obtain a cylindrical woven matter in which the face side and the back side are joined to each other at both edges. In this process, a yarn spun from a heat-fusible fibers is used intermittently as a weft, whereby extremely narrow bands 2 in which said yarn is used as the weft are provided at regular intervals in the cyindrical body. After weaving, the weft in the bands 2 is converted into a film at a temperature at which only the part of the fibers having a low melting point is melted, thereby forming borderlines. The cylindrical body thus obtained is cut in the weft direction at the regular intervals. The band thus obtained by dividing along the borderlines is coated or impregnated with an ink with a desired color (namely, the band is inked).

Abstract: PURPOSE:To increase the arithmetic accuracy and to increase the yield of the IC information for the focusing method of the frequency analyzing system by  performing an alternate operation to the outputs given from two sets of light receiving parts through an arithmetic processing circuit. CONSTITUTION:An alternate operation 13 is performed to the output signals which are given from the photodetectors 1 and 2 via the current-votage converters 3 and 5, and these signals are sampled and held 14 and 15. Thus a control circuit 16 opens and closes the gates TG1-TG4 with the prescribed timing, and the outputs of the converters 3 and 5 are fed alternately to an arithmetic processing circuit 13 with each cycle. The sample holding circuits 14 and 15 hold the arithmetic results of the outputs of the converters 3 and 5 respectively, and then the outputs of both circuits 14 and 15 are fed to a difference detecting circuit 7 and a focusing deciding circuit 8 to control a lens driving motor and a display device 12. In this case, the arithmetic result is shifted by a cycle through the holding circuit, and shift can be reduced in comparison with the second value of the camera shake to be ignored. As a result, the arithmetic accuracy is increased with the integration of the arithmetic processing circuit, and at the  same time the yield is increased for the IC formation.
