Title: Optical data transmission equipment
Inventor: MIBU TAKAHIKO
IPC: H04B10/00
Filed: 1989-04-18
Abstract: PURPOSE:To obtain a stable clock signal in spite of the content of transmission data by transmitting the clock signal by using an optical signal with wavelength band independent of a data signal. CONSTITUTION:The data signal 1 is converted to the optical signal with the wavelength lambda1 by an optical transmitter 10, and simultaneously, the clock signal 2 is converted to the optical signal with the wavelength lambda2 by an optical transmitter 11. The data signal converted to the optical signal with the wavelength lambda1 and the clock signal converted to the optical signal with the wavelength lambda2 are synthesized by an optical multiplexer, then, it is transmitted via an optical fiber 5, and after that, it is demultiplexed to the optical signal with respective wavelength band by an optical demultiplexer 13, and the optical signal with the wavelength band lambda1 is inputted to a first optical receiver 14, and the optical signal with the wavelength band lambda2 to a second optical receiver 15, respectively. Since the clock signal 2 is transmitted after being converted to the optical signal with the wavelength band lambda2 independent of the data signal 1, the clock signal can be stably reproduced in spite of the content of the data signal 1.

IPC: G11B23/087
Filed: 1989-04-19
Abstract: PURPOSE:To reduce shock to a magnetic tape, which is wound at high speed, and to prevent the drop out of the magnetic tape by specifying the curvature radius of an apex part in a projecting rib formed on a friction sheet. CONSTITUTION:A friction sheet 5 is inserted among a magnetic tape 4, hub 3, a around which the tape 4 is wound, and halfs 1 and 2 forming a case.
