Title: Multicolor simultaneous connector for optical fiber
Inventor: WATANABE TSUTOMU
IPC: G02B6/24
Filed: 1988-03-14
Abstract: PURPOSE:To stabilize the clamping state of respective optical fibers and to prevent the axial misalignment at the time of welding the optical fibers by providing elastic bodies to the parts where clampers come into contact with the optical fibers. CONSTITUTION:The elastic bodies 4 consisting of, for example, foamed plastic, etc., are provided to the surfaces where the clampers 3 come into contact with the optical fibers. The elastic bodies 4, therefore, absorb the difference in the outside diameter of the optical fibers 1 even if said outside diameters differ. Downward force acts on the respective optical fibers 1 and even the optical fibers having the small outside diameters can be exactly positioned into V- grooves 21. Exertion of the excessive pressure on the optical fibers 1 in the vertical direction thereof and the increase in friction resistance between the fibers and the elastic bodies 4 are prevented by providing longitudinal notches to the elastic bodies 4 or applying a coating on the surfaces of the elastic bodies on which said bodies come into contact with the optical fibers 1 in the case of the optical fibers 1 having the large outside diameter.

Abstract: PURPOSE: To fractionatingly recover respective pyridine bases from a pyridine base mixture with small energy and low equipment cost in a simple operation. CONSTITUTION: Benzopinacol is mixed with a mixture comprising plural pyridine bases to carry out clathrate complexing reaction between at least one kind of pyridine base and the benzopinacol; the pyridine base(s) not formed clathrate complex(es) is distilled out at a temperature below the decomposition temperature of the clathrate complex(es) from the resultant reaction mixture and the clathrate complex(s) is then heated to a temperature higher than its decomposition temperature to liberate and distill out the pyridine base(s) in the clathrate complex(es), thus separating the pyridine base(es) from the others. By this method, the respective pyridine bases can be fractionated and recovered from a mixture containing 3-picoline and 4-picoline both having similar boiling points and having been highly hard to mutually separate by conventional fractionating processes.

Title: Flattening method
Inventor: YOSHIDA SATOSHI
IPC: H01L21/3213
Filed: 1985-03-27
Abstract: PURPOSE:To obtain an extremely flat surface regardless of a pattern size by subjecting the resist surface formed by embedding the recesses on the surface of an insulating layer having ruggedness with a dummy resist and coating further the resist thereon to ion incidence at two stages of angles. CONSTITUTION:A lower magnetic layer 13, a conductor layer 11 and an insulating layer 15 are successively formed on a substrate 14 and since the surface is made rugged by underlying conductor coils, the photoresist 16 is coated in the recesses thereof and the resist 17 is further coated thereon to embed the small recesses of the resist 16. The resist 16 is heat-treated at >=200 deg.C to prevent the melting with the resist 17. The ions are made incident at 30-45 deg. angle to the surface of the resist 17 to prevent the generation of the ruggedness on the surface. The SiO2 of the layer 15 and the resist are etched at the same speed and 75 deg. ion incident angle and thereafter a magnetic layer 18 is formed. The recording and reproducing efficiency is thus improved by two stages of etching for flattening.

Abstract: PURPOSE: To shift a commodity by a fixed distance by memorizing the external diameter of constant-plane-shaped commodities, mounted on a moving method in a line, as a quantized picture and by detecting the positions of commodities judging from the position information a partial picture detected afterwards.  
     CONSTITUTION: The expanded image of a group of pellets 2 is picture-taken by TV camera 4 to obtain a binary figure through Ad conversion, and the 1st position detection part 8 perform an arithmetic process to find positions of four corners. In other words, XY table 3 is moved slightly until an expected-point output is obtained as to reference patterns P 1  to P 4 . After expected points S 17  to S 20  are obtained, the size of pellet 2 and center coordinates are calculated from their coordinates and the movement of table 3. Using size information obtained by detection part 8, the 2nd position detection part 9 computes the center position coordinates from at least one corner- position cordinates. Lastly, table 3 is moved by a fixed distance according to a prescribed order and detection parts 8 and 9 are controlled and driven 10 to detect the positions of all pellets on jig 1. At this time, detection part 8 detects the position and pellet size once or several times and then, position detection 9 is performed by using the obtained information, so that high-speed position detection can be realized from a small number of corner positions.
