Title: Single line bi-direction optical transmitting device
Inventor: SATOU FUMIHIKO
IPC: H04B10/00
Filed: 1981-05-13
Abstract: PURPOSE:To use a Y-branching device for a single line bi-direction transmission line, by setting a branching ratio of the Y-branching device larger in the photodetector side than in the light emitting element side. CONSTITUTION:Between branch lines of fiber branching devices 15, 16 manufactured so as to constitute a Y-branching line, a branch line coupled with light emitting elements 11, 14 is formed to a smaller diameter than a branch line coupled with photodetectors 12, 13. According to this constitution, a light beam of wavelength lambda1 emitted by the element 11 is made incident from one branch line of the branching device 15, reaches the branching device 16 through an optical fiber 17 from its base line, and is transmitted to the photodetector 12 from the branch line of a large diameter. The branching device 16 is set so that the extent of branch to the photodetector 12 side becomes larger than the extent of branch of the element 14 side, therefore, the greater part of the wavelength lambda1 is made incident to the photodetector 12. A light beam of wavelength lambda2 from the element 14 is also transmitted to the photodetector 13 through the branching device 16, the fiber 17 and the branching device 15 in the same way. In this way, single line bi-direction transmission of a light beam is executed.

Title: Reproducing unit for recording disc
Inventor: ABE MASAHIRO
IPC: G11B3/12
Filed: 1979-06-11
Abstract: PURPOSE: To make constant the pressure relation between the disc surface and the stylus and to lower the mechanical impedance of the reproducing pickup stylus substantially, by picking up the change in the stylus pressure as a signal and operating the driving unit with the signal.  
     CONSTITUTION: The uneven signal recorded on the disc 2 is traced with the reproducing stylus 7, the pressure change of the stylus produced with the uneven signal is converted into electric signal with the mechanical-electro conversion element, and amplification is made so that desired output can be obtained with the head amplifier 11. The reproduced output signal is obtained at the output terminal of the signal processing circuit 12. A part of the signal 20 amplified at the amplifier 11 picks up the envelope of the signal at the envelope detector 14. In this case, when the stylus 7 keeps the desired stylus pressure, the output signal 19 of the detector 14 is a given voltage value, but if the stylys pressure is subjected to change due to the surface oscillation of the disc 2, the signal 19 changes with the period of the change in the stylus pressure. Further, the current corresponding to the change in the stylus pressure flows to the coil 8, allowing to operate the permanent magnet 6 and control the stylus pressure to a constant value through the set of the stylus pressure to a desired value.
