Abstract: PROBLEM TO BE SOLVED: To provide a light amplifier that can be freely changed in direction of amplification. SOLUTION: A light amplifying fiber 24,a wavelength multiplexer 26, and an optical circulator 28 are connected in series between signal light input/output terminals 20 and 22. Exciting light is inputted into the wavelength multiplexer 26 from an exciting light source 30. Exciting light emitted from the exciting light source 30 is directed to the light amplifying fiber 24 by the wavelength multiplexer 26. The optical circulator 28 is equipped with three ports A, B, and C and can be reversed in the direction of rotation by reversing an applied magnetic field.  That is, either the one direction of rotation where the optical circular 28 outputs light inputted through the port A through the port B and outputs light inputted through the port B through the port C or the other direction of rotation where th optical circulator 28 outputs light inputted through the port B through the port A and outputs light inputted through the port A through the port C can be selected from outside. The port A of the optical circulator 28 is connected to the wavelength8 multiplexer 26, the port B is connected to the input/output terminal 22, and the port C is connected to a non-reflection terminal end 32.

Title: Control method for air spring vibration eliminating table or mass damper and controller therefor
Inventor: YASUDA MASASHI
IPC: F16F15/02
Filed: 1990-09-18
Abstract: PURPOSE:To reduce the manufacturing cost and a space required for a device by controlling an air pressure of a pilot chamber, in balance with an air pressure inside an air spring support leg, on the basis of an electric signal, and controlling the air pressure inside the air spring support leg according to fluctuation in air pressure of the pilot chamber. CONSTITUTION:If a vibration eliminating base table 2 is discended lower than a reference level with application of a load, a control current flows in an electromagnetic coil 28 of a pilot chamber control valve 8. A vibrating valve 27 supplies air from a primary side air pressure source 5 into a pilot chamber P on the basis of a signal, to push down a switch valve 10. The air is supplied into a pressure container 16 from the primary side air pressure source 5 through a secondary side pipeline 7, thereby pushing up the vibration eliminating base table 2. As soon as the vibration eliminating base table 2 accordingly reaches a reference position, the flowing of the air in the pilot chamber P from the primary side air pressure source 5 is stopped. Therefore, the vibration eliminating base table 2 returns to the reference level. Control of the air pressure of the pilot chamber P of a small capacity enables the air pressure inside the pressure container 16 of a large capacity to be controlled.
