IPC: G02B6/38
Filed: 1982-05-13
Abstract: PURPOSE:To align the axes of optical fibers having a variation in outside diameter with high accuracy and to connect said fibers by using an elastic material for a cylindrical bar or cylindrical pipe to be used for axial alignment. CONSTITUTION:Elastic material bars 1, 2, 3 are disposed, and optical fibers 4, 5 are inserted into the triangular gaps formed by the circular cylinders thereof and after the fibers are fixed tentatively, a heat shrinkable tube is heated and calked onto the fibers to align the axes of the optical fibers and to fix the fibers, whereby the fibers are connected. If an elastic material having small Young's modulus, such as a nylon rod, is used for the elastic material bar, the diameter of the nylon rod can be changed by calking the same with the heat shrinkable tube or the like; therefore, the outside diameter of the optical fibers to be connected has a degree of freedom, and the connection of the optical fibers having different outside diameters is made possible.

Patent JP-S555184-A (JP)
Title: Arc welder
Inventor: HAGIWARA SEIGO
IPC: B23K9/073
Filed: 1978-06-29
Abstract: PURPOSE: To enable DC of small ripple rates to be obtained with a simple constitution by respectively parallel connecting the two SCRs and two reactors which are series-connected on their same polarity side to both side terminals of the secondary winding of a transformer and connecting welding load to the connecting point of the SCR and reactor.  
     CONSTITUTION: When output terminal (a) is plus, terminal (b) is minus and an SCR 2b is conducting, then current flows through terminal (a) → reactor 6a → base metal 5 → arc 4 → welding torch 3 → SCR 2b → terminal (b). As the current  begins to decrease, an induced voltage which forward biases the SCR 2a is generated through the arc 4 in the reactor 6a and tries to continue to flow the current in the same direction even after the polarity inversion of the terminals (a), (b). Here, when a gate signal enters, the SCR 2a is forward biased and therefore goes ON and the SCR 2b goes OFF. At this time, the current abruptly inverts its polality, thus the DC of small ripple rates may be obtained.

Filed: 1978-06-30
Abstract: PURPOSE:To secure nearly the same level for the DC action points of the input and output terminals by giving the collector potential control to the transistor at the input side in proportion to the collector potential of the transistor at the output side of the differential amplifier, and thus to secure a facilitated formation of the IC.

Title: Disturbance compensation type optical position detector utilizing faraday effect
Inventor: TOGAWA MASAYUKI
IPC: G01D5/26
Filed: 1988-03-31
Abstract: PURPOSE:To measure an accurate position at all times without any adverse influence of the presence of foreign matter and dew condensation in a measurement optical path by inserting a couple of Faraday optical elements which have polarizers and analyzers respectively into the hollow part of a cylindrical magnet. CONSTITUTION:When the cylindrical magnet 28 is displaced as shown by an arrow X, the quantity of light detected by a photodetector 27 varies like a signal A as length l1 increases. At the same time, the quantity of light detected by a photodetector 27' varies like a signal B since length l2 decreases. Those two signals A and B are processed by the subtraction of a subtracter 30 to obtain a signal C. Then the maximum values DELTAA and DELTAB of the error between signals before and after temperature variation are generated as errors by A and B in the signal C, and a signal of a position is extracted as an output C by the subtracter 30 as the difference signal between position signals outputted by the photodetectors 27 and 27'. Therefore, the ratio of the signal and error is improved by about twice.
