Title: Clamp device
Inventor: MORI YOSHIZO
IPC: H04N5/378
Filed: 2000-08-28
Abstract: PROBLEM TO BE SOLVED: To calculate the mean output value of pixels for optical black by excluding the outputs of defective pixels. SOLUTION: An image processing CPU 4 sets a register C at zero (C=0) and the total number H of the pixels for optical black(OB) at 100 (H=100) (step S101) and sets a pixel number h for OB at 2001 (h=2001) (step S102). Then the CPU 4 reads out the output values d(M, h) of the pixels for OB from a memory 5 (Fig. 1) (step S103) and judges whether or not the output values d(M, h) of the pixels for OB correspond to defective pixels (step S104). When the CPU 4 judges that the values d(M, h) correspond to the defective pixels, the CPU 4 subtracts '1' from the total number H of the pixels (step S105). When the CPU 4 judges that the values d(M, h) do not correspond to the defective pixels, the CPU 4 adds the output values d(M, h) of the pixels for OB to the register C (step S106). Then the CPU 4 judges whether or not the pixel number h for OB is 2100 (step S107).  When the CPU 4 judges that the number h is not 2100, the CPU 4 adds '1' to the number h and returns to the step S103 (step S109). When the CPU 4 judges that the number h is 2100, the CPU 4 calculates the mean value C(M) by dividing the value of the register C by the total number H of the pixels (step S108).

Title: Ferrule for facilitating contact between fiber and fiber and its manufacturing method
Inventor: CHILDERS DARRELL R
IPC: G02B6/38
Filed: 2000-09-06
Abstract: PROBLEM TO BE SOLVED: To provide a ferrule, which makes it easy to bring fibers into contact with each others without projecting optical fiber endts from the front of the ferrule, and its manufacturing method. SOLUTION: This ferrule has a ferrule body (12) having a front surface (14) and a rear surface (16) which facing in the opposite directions and the ferrule body has at least one optical fiber hole (18) extending between the front and rear surfaces. It is advantageous that the center part of the front surface where at least an optical fiber hole is open projects out from a certain place of the peripheral edge part of the front surface. Thus, the front surface is so designed that the front surface center part projects out from the front surface peripheral edge part and then when respective fiber optical contactors are connected, none of the angle error of the front peripheral edge part, and dust and other particles settling at the front peripheral edge part impedes the contacting of a couple of ferrule front center parts.  In the mentioned case, an optical fiber end part need not extend large even when it should extend from the ferrule front surface so as to establish the contacting between the fibers and when the front extends large, the force applied to all the fibers can be absorbed by the ferrule to some extent.
