Title: Optical fiber cable stabilized in low-temperature characteristic
Inventor: SUGANOU TAKASHI
IPC: G02B6/44
Filed: 1990-02-09
Abstract: PURPOSE:To maintain and continue the stable transmission of light signals in an expected low-temp. environment by previously applying such a pretension as to satisfy a prescribed value to an optical fiber. CONSTITUTION:The tension is previously applied to the optical fiber or coated fiber so as to satisfy the relation shown by alpha.DELTATX100-(epsilonf-epsilons)<epsilonc where the coefft. of linear expansion of the cable is designated as alpha ( deg.C<-1>), the temp. difference from ordinary temp. to a low temp. as DELTAT( deg.C), the elongation strain by the tension applied on the fiber or coated fiber of the optical fiber 4 as epsilonf(%), the elongation strain by the back tension applied on the spacer 2 as epsilons(%), and the shrinkage strain of the cable to initiate a transmission loss in the optical fiber or coated fiber as epsilonc(%). Namely, the previously calculated elongation strain is previously applied on the optical fiber. The elongation strain previously applied on the fiber at ordinary temp. is conversely released and relieved at a low temp. when the fiber is used in the environment of the low temp. The stable light transmission is thus continued and maintained.

Title: Id protection device
Inventor: KIJIMA TATSUSHI
IPC: G11B20/18
Filed: 1989-02-13
Abstract: PURPOSE:To improve error correction efficiency by comparing ID data detected by a detecting means with the ID data generated by a generating means, and selecting either. CONSTITUTION:A signal string inputted from an input terminal 1 is inputted to an ID detector a 4, and the ID data in the signal string is detected by a synchronizing signal inputted from an input terminal 2. Also, an ID generator a 3 is reset to 0 at the switching timing of each track, and is comprised of a counter counted up by the synchronizing signal, and generates the ID data in prescribed sequence. And the ID data generated from the generator a 3 is compared with the ID data detected by the detector a 4 by an ID comparator a 5. When noncoincidence is obtained, an operation to substitute the ID data for data in a reproducing signal string is performed, and the signal string in which the ID data is substituted at a selector 6 is corrected at an error corrector 7. Thus, it is possible to heighten the error correction efficiency by performing error correction after substituting predicted ID data.
