Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing an optical fiber cord with a ferrule which allows the execution of the work to mount the ferrule in the state of preventing tensile fibers from loosening to pieces. SOLUTION: A jacket 3 of the optical fiber cord 4 having a jacket 3 via tensile fibers 2 on the outer side of an optical fiber 1 is stripped for a prescribed length to form an exposed optical fiber part 5 and an exposed tensile fiber part 6. After the exposed tensile fiber part 6 is cut away for a prescribed length, a first adhesive 8 is applied on the remaining exposed tensile fiber part 6 and the exposed optical fiber part 5 is passed into the through-hole 10 of a forming cap 9 having the through-hole 5. The exposed tensile fiber part 6 is then inserted therein and the first adhesive 8 is allowed to cure in this state to mold the exposed tensile fiber part 6 to a conical shape having the exposed optical fiber part 5 at its central axis.  The forming cap 9 is thereafter removed and the ferrule is mounted via a second adhesive on the outer side of the exposed tensile fiber part 6 and the exposed optical fiber part 5.

IPC: G01B11/00
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To detect the position of an IC package accurately without the effects of the defective shapes such as chips and burrs on the package. SOLUTION: The boundary of the upper surface and the side surface of a package is detected by hystogram. The linearity of the continuous distribution of respective dots is detected from the differentiated value of the distribution of the boundary points. Furthermore, the straight line of the package boundary is detected by a least square method from the remaining dot after the nonlinear part by a chip part 12 is removed. Furthermore, the intersection point of the detected straight lines in the direction (x) and the direction (y) is made to be an original point 19. The straight lines (x) and (y) are rotated by the equal angle, respectively, so that the cross angle of two straight lines becomes 90 degrees with the original point 19 as the center, and a reference axis X in the direction (x) and a reference axis Y in the direction (y) are computed.  Thus, even if there are chips, burrs and the like, the IC position can be accurately detected, and the detecting positions of the defective items on visual inspection, the detecting position of a lead and the like can be accurately set.

IPC: G03G15/00
Filed: 1996-01-05
Abstract: PROBLEM TO BE SOLVED: To perfectly achieve image displacement correction in a color image forming device using an electrophotographic system. SOLUTION: A difference between the time required for a detection sensor 7 to detect a mark 30 after a driving roller 6 is rotated from the initial condition in which the rotation home-position 14 of the driving roller 6 corresponds with the position where the detection sensor 7 detects the mark and the time required for the driving roller 6 reaches the home position 14 after rotating (n) times is measured. The time required to detect the mark 30 is subtracted from the time required to reach the home position 14, and the average speed of an intermediate transfer belt 5 is divided by this value, thereby calculating a distance the intermediate transfer belt 5 has advanced during one image- formation process and also calculating the error (s) of the diameter corresponding to the displacement. Therefore, by reducing the substantial diameter of the driving roller 6 only an amount corresponding to the error (s), displacement can be prevented.
