Title: Bidirectional optical amplifier and nonlinear loop mirror
Inventor: IWATSUKI KATSUMI
IPC: G02F1/35
Filed: 1994-05-06
Abstract: PURPOSE:To provide a bidirectional optical amplifier which amplifies light signals in two directions by using a progressive wave semiconductor laser amplifier while preventing the adverse influence of the reflected light at its end face and to prevent deterioration in characteristics by the end face reflection of the progressive wave semiconductor laser amplifier of a nonlinear loop mirror which executes sepn. of light pulses by utilizing the nonlinear effect of the progressive wave semiconductor laser amplifier. CONSTITUTION:Polarizers 13, 23 and Faraday rotors 14, 24 are arranged respectively on both sides of the progressive wave semiconductor laser amplifier 10. The linearly polarized waves past these polarizers 13, 23 are rotated 45 deg. in directions respectively backward from each other by the Faraday rotors 14, 24 and are made incident on the progressive wave semiconductor laser amplifier 10. The light signals past the progressive wave semiconductor laser amplifier 10 are respectively returned to the original linear polarization state by the Faraday rotors 24, 14 and are passed through the polarizers 23, 13. The light reflected at the end face of the progressive wave semiconductor laser amplifier 10 varies in the polarization state and cannot, therefore, pass polarizers 13, 23.

Title: Level meter
Inventor: SHIMAGAMI KAZUTO
IPC: G11B27/36
Filed: 1985-05-07
Abstract: PURPOSE:To display a saturation level at low cost by displaying the magnetic saturation level of a magnetic tape on the same meter together with a recording or reproducing level and replacing the brightness of an exceeding part or that of the saturation level display with that of the meter. CONSTITUTION:A CPU makes an oscillator output the prescribed signal used for detecting the magnetic saturation level. The signal is recorded and reproduced to be at the saturation level, converted into a digital signal by an A/D converter, and stored in a saturation level memory device. During the sound- recording action or reproducing action a reproducing signal or a recording input signal is A/D converted, dots at the level or dots below the level are lighted and the dot equivalent to the saturation level stored in the saturation level memory device. When the recording level or the reproducing level exceeds the magnetic saturation level, the brightness of the level meter corresponding to the exceeding part is replaced with the other one. Thus the magnetic saturation level can be displayed without raising the cost of the level meter.
