摘要： PURPOSE:To obtain a rotary joint which has a hollow shaft by providing a rotary body with a conical wheel and columnar wheels crossing the hollow shaft of a fixed body and making a rotation-side optical fiber signal incident on a fixed-side optical fiber through the columnar wheel. CONSTITUTION:The conical wheel 8 whose axis crosses the hollow shaft 16 of the fixed body 7 is provided in a rotary body 1. The columnar wheels 4a and 4b which rotate along the peripheral surface of the conical wheel 8 are provided and a rotary-side optical fiber 2 is run through them. The incidence end of the fixed-side optical fiber 12, on the other hand, is positioned on the axis of the wheel 8. In such constitution, the optical fiber signal of the rotary side is made incident on the fixed-side optical fiber 12 through the projection ends of the columnar wheels. Consequently, neither a prism nor a rod lens is used, the transmission loss becomes extremely smaller. Further, a joint center part is a hollow shaft, so this joint can be utilized for a supply system for liquid, electricity, gas, etc.

摘要： PROBLEM TO BE SOLVED: To provide a system for measuring physical amounts of many points which can measure without being influenced by a level change of a light source or a photodetector and by a distance. SOLUTION: In a multi point-measuring apparatus 1, a photodetector 4 for detecting light is connected at one end of an optical fiber 2a. A signal-processing circuit 5 is connected at a rear stage of the photodetector 4 to analyze frequency components of signals converted by the photodetector 4 to electric signals. OScillators of optical physical amount sensors 6a, 6b, 6c... oscillate with a frequency corresponding to a physical amount and an intensity of projected light is modulated by a voltage at a light source. Accordingly, a change of the physical amount is converted to a change of an intensity modulation frequency of the source light. Since information of the physical amount is transmitted by frequency information, the transmission is not influenced by the attenuation of light due to a level change of the light source or photodetector 4 and a distance of the optical fiber 2a.

摘要： PURPOSE:To improve a laser diode module in precision by a method wherein the angle adjustment and the fixing of an LD holder are easily made through the adjustment of a spherical sheet and laser welding, an LD holder is made to rotate freely to an optical axis to enable the rotational positioning of the major and the minor axis of the LD beam to be easily made, and other processes. CONSTITUTION:An LD holder 10 is displaced and adjusted in angle as being in contact with a fixed body 20 so as to make an outgoing beam from a light emitting section 2 parallel with an optical axis 52, and then the joint 8 between the LD holder 10 and the fixed body 20 is irradiated with laser ray 9 to weld the holder 10 and the body 20. As the LD holder 10 is able to rotate freely to an optical axis, the rotational positioning of the major and the minor axis of an LD beam can be easily made and consequently a laser diode may be just freely placed in the LD holder 10. When the level precision of the whole head is measured, the characteristic can be obtained through a module alone, so that the comparison of precision can be easily made thereafter and the module can be improved in precision.
