Title: Plug pin for light waveguide body loadable into pin bush and manufacture thereof
Inventor: HORUSUTO FUYUUBUNERU
IPC: G02B6/38
Filed: 1988-06-28
Abstract: PURPOSE: To conduct a low-loss connection over a wide temp. range by matching the wall thickness of a sleeve with that of a core tube and making the obtained thermal expansion coefficient of the plug pin almost equal to that of the material of the pin bush. CONSTITUTION: The wall thickness of a sleeve 3 is matched with that of a core tube 2, and the obtained thermal expansion coefficient of a plug pin is made almost equal to that of a pin bush 4. The wall thickness of the sleeve 3 is so minimized that the optional and desired amt. of the material is removed by turning, for example, in the centering stage. The expansion of the plug pin is limited by the low thermal expansion coefficient of the material of the core tube 2 instead of the high thermal expansion coefficient of the soft material of the sleeve 3. Since the relative thickness between the core tube 2 and sleeve 3 and the material are combined in this way, the gap between the plug pin and pin bush 4 is made almost independent of the temp.

Title: Semiconductor optical waveguide
Inventor: NAKAMURA SHIGERU
IPC: G02F1/015
Filed: 1991-07-01
Abstract: PURPOSE:To enable high-speed optical modulation with light by shortening the recovery time of nonlinear variation in refractive index due to light absorption. CONSTITUTION:When a waveguide is irradiated with control light pulses, electrons and positive holes are generated in a core 3 by light absorption to cause the nonlinear refractive index variation. When light to be controlled is guided in the waveguide, phase modulation is imposed by the refractive index variation. When neither of the electrons and positive holes is present in the core 3, the core recovers from the nonlinear refractive index variation. Here, the lowest energy potentials 8 and 11 of the electrons and positive holes in the core 3 in multiple-quantum well structure are made higher than the lowest energy potentials 9 and 12 of clads 2 and 3 and then the electrons and positive holes generated in the core migrate to the clad in a time shorter than a rebonding time. Consequently, the core recovers from the nonlinear refractive index variation in a time shorter than the re bonding time.

Title: Manufacture of crosslinked polyethylene pipe
Inventor: TERACHI SHINJI
IPC: B29C48/32
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To inhibit the generation of scorch and enhance the quality by kneading a masterbatch of a polyethylene resin with a specific density obtained by polymerization using a metallocene compound and a vinyl silane compound with a powdered organic peroxide at a specific one-minute half-life period temperature and adding a silanol condensation catalyst to the mixture and extruding it to crosslink the extruded product under specific conditions. SOLUTION: A masterbatch M of a polyethylene resin R with 0.932-0.941 g/cm3 density obtained by polymerization using a matallocene compound and a vinyl silane compound is kneaded with a powdered organic peroxide C1 which acts as a radical polymerizing catalyst at 150-250 deg.C one-minute half-life period temperature, with the help of a hopper H of an extruder. The mixture is plasticized by setting the internal temperature of a cylinder at a higher temperature than the melting temperature of the resin R and at a lower temperature than the one-minute half-life period temperature of the organic peroxide C1. Further, the plasticized mixture is kneaded at the half-life period temperature or higher and then a slianol condensation catalyst C2 is added.  In addition, pipes obtained by extruding and shaping the molten resin R are brought into contact with moisture V and then are crosslinked at 65% or more gel fraction by condensation reaction of the catalyst C2. Thus it is possible to obtain the crosslinked polyethylene pipe which shows a uniform cross link density and outstanding creep characteristics and further is free from scorch.
