摘要： PURPOSE:To simplify the constitution and to make the configuration compact, by converting two kinds of optical pulse-width signals into an air-pressure-signal through the first and second optical energy absorbing members, the first and second pneumatic switches and a tank. CONSTITUTION:The optical energies of two kinds of optical pulse-width signals including the data in time lengths from optical fibers 11 and 12 are absorbed by absorbing members 21 and 31. One end of a first pneumatic switch 2 is connected to an air pressure feeding source 4, and the other end is connected to a tank 6. One end of a second pneumatic switch 3 is opened, and the other end is connected to the tank 6. The part between the two terminals of the switches 2 and 3 is turned ON and OFF by the deformation of the members 21 and 31 by the absorption of the optical energy. An air pressure signal, which is associated with the optical pulse-width signal, is outputted from an output terminal 5 through the tank 6.

摘要： PURPOSE:To make a device compact, by providing a hollow optical fiber having a hollow part in the axial direction, connecting an air feeding source to a hollow part, and feeding the air. CONSTITUTION:An optical fiber 6 is connected to a hollow optical fiber 1 having a hollow part 2 in the axial direction. The hollow part 2 and the outside are communicated by a communicating path 7 of a connecting device 4. An air feeding source 9, which feeds the air to the hollow part 2, is connected to the communication path 7. When a light signal is projected from a tip 3a of a clad part 3, a flapper 11 absorbs the light and advances toward the tip 3a so as to narrow the gap. Therefore, the back pressure is increased by the input air pressure Ps, which is supplied to the hollow part 2. The output air pressure Po, which is exhausted to an output side 12a of a pilot relay 12, is increased. Thus, the output air pressure Po, which is proportional to the input of the light signal, can be obtained.

摘要： PURPOSE:To provide the higly efficient apparatus with a simple construction by utilizing a displacement accompanied by the expantion and contraction of a photoresponsive material when a light signal transmitted through a fiber is irradiated into the material. CONSTITUTION:A signal to be measured is transmitted from one end of fibers 11 and 12 on pulse width signals S1 and S2 of light. This light signals S1 and S2 are irradiated into a belloweses 21 and 22 from the other end of fibers 11 and 12 and light energy is absorbed into photoresponsive materials 31 and 32 which are expanded heated thereby stretching the belloweses 21 and 22. The degree of stretch of the bellows corresponds to the light energy (duty ratio) of the light pulse signal irradiated and a differential lever 4 displaces according to the difference between the duty ratios t1/T and t2/T of the light signals S1 and S2. The displacement of the differential lever 4 drives a pointer 6 thrugh a link mechanism 5 enabling the magnitude of the signal transmitted to be indicated from the shifted position of the pointer.
