IPC: H02G1/12
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To remove the tape covering of an optical fiber tape core without requiring skill, without damaging optical fiber cores and in a short time. SOLUTION: After the tape covering 3 of one side end part of an optical fiber tape core 1 is removed and respective optical fiber cores 2 are exposed, the exposed parts are inserted into a brush and hairs 6 of the brush are made to cut into the covering between the respective optical cores 2 (a). The brush is moved in the longitudinal direction of the tape core 1 to make slits extend from the optical fiber core exposing part C side in the longitudinal direction of the tape core 1 in the remaining tape covering 3 to divide the optical fiber tape core 1 into optical fiber cores 30 with tape coverings at least to the middle part (b).  The optical fiber core exposing part C is inserted between the hairs 7 of the brush, while the taped parts of the optical fiber cores 30 with the tape coverings are stroked and the tape covering 3 with the slits is caught by the hairs 7 and removed from its tip side.

Title: Magnetic recording and reproducing device
Inventor: OBARA NAGAYOSHI
IPC: H04N9/80
Filed: 1985-10-30
Abstract: PURPOSE:To record superimposingly a stereo sound signal on a video signal in recording a SECAM signal by narrowing a band of a low frequency conversion chrominance signal and inserting a sum and a subtraction signal of a stereo sound signal by the share and recording them as frequency modulation signals. CONSTITUTION:The frequency modulation wave of a SECAM chrominance carrier signal is expressed in an equation I, where omegac=2pifc, omegap=2pifp and DELTAomega=2piDELTAf. In applying 1/4 frequency division to the equation I, an equation II is obtained. The carrier frequency is 1/4fc from the equation II, a modulation index beta=DELTAf/fp is realized and the frequency shift is 1/4 and the required frequency band is 1/4. Thus, a chrominance signal processing section 52 applies frequency division to form a low frequency conversion chrominance signal, the frequency allocation of the recording video signal including the signal is further narrowed and the low frequency conversion chrominance signal band is nearly 1/4. As a result, a margin band exists between a frequency-division modulation luminance signal band and a pilot signal band and frequency modulation sound signals L+R and L-R being the sum and difference signals of the left/right channels are inserted to the margin band.

Abstract: PROBLEM TO BE SOLVED: To read an image by using a picture element density around a dirt area so as to interpolate density data of an image of the dirt area on an original through a reflected light from the original thereby surely eliminating the dirt of a multi-value image. SOLUTION: A high pass filter eliminates a low frequency fluctuation component of data of a linear image 41 with respect to its X coordinate stored in an image memory 38, and a low frequency elimination linear image in which y-coordinates of dirt part 42 corresponding to a dirt are set higher and y- coordinates of parts without dirt are set lower is obtained. Then the y- coordinates of a low frequency elimination linear image 43 representing detection of the dirt area are binarized by a prescribed threshold level ys and x- coordinates x1, x2 corresponding to both ends of a part larger than the ys are detected. Then a laser light source 10 is turned off and a fluorescent lamp 11 is turned on and an original emission slit light being a white light is emitted in the subscanning direction of an original 3. Then the linear image of the slit light is formed on a CCD 17.  Thus, the dirt is surely eliminated and the resulting image is read.
