Title: Optical coupler
Inventor: SASAGAWA YOSHIKAZU
IPC: G02B6/28
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To provide an optical coupler which has both a function for multiplexing two lights and a function as an optical isolator and is suitably reducible in size. SOLUTION: First and second optical fibers 12 and 13 are coupled by fusion splicing at a specific distance from their projection ends. The light projected from the output port 16 of the fusion-splicing coupling part is converged by a 1st condenser lens 17 and passed through the optical isolator 17, and the light passed through the optical isolator is converged by a 2nd condenser lens and inputted to a 3rd optical fiber. Thus, the light is projected directly from the part of the projection end where the two optical fibers are optically coupled with each other, so the need for a distance for branching the light to the two optical fibers again is eliminated and the optical coupler is reducible in size.

Filed: 1986-10-09
Abstract: PURPOSE:To certainly supply a proper amount of a powder to the tip of a pen, by relatively rotating a receiving pipe having the powder received therein and a spiral body and successively guiding the powder for cosmetics or writing forwardly by the spiral inclined surface of the spiral body. CONSTITUTION:When the tip 2 of a pen is slightly inclined downwardly and an operation knob 8 is rotated with respect to a shaft cylinder 1 by a fingertip, the spiral body 6 fixed to the knob 8 also integrally rotates. Since the powder received in a receiving pipe 3 is preliminarily moved to the vicinity of the forward small diameter part 5 of the receiving pipe 3 under its own wt., the powder is led out little by little to be introduced into the forward small diameter part 5 by the rotation of the spiral body 6 while the forward movement thereof under its own wt. is suppressed by the spiral inclined surface 7 of the spiral body 6 and supplied in the tip 2 of the pen by the spiral inclined surface 7 displacing under rotation. At this time, by appropriately regulating the rotation of the operation knob 8, the supply amount of the powder becomes a desired one.

IPC: H04N1/407
Filed: 1987-09-26
Abstract: PURPOSE:To obtain a copy with fidelity by designating an area in a picture and applying different gradation processing depending on the inside and the outside of the designated area. CONSTITUTION:A gamma correction/conversion circuit 103 applies different gradation processing to each area in an original 1 where a picture area 1a and a character area 1b exist in mixture. That is, and a gamma correction processing table of a gamma correction curve is selected so as to attain 1:1 of input : the output from white to black levels including the intermediate tone part so as to reproduce the gradation of an original picture with fidelity in the area 1a. On the other hand, the gamma correction processing table of the gamma conversion curve with a high contrast is selected in an area 1b so as to prevent the pickup of the undesired background color or rear color. Thus, even when a medium with different gradation characteristic such as character or line drawing exists in mixture in one and same original, optimum gamma correction in matching with each gradation is applied and more fidelity copying with the original is attained.
