Title: Optical isolator
Inventor: SHINTAKU TOSHIHIRO
IPC: G02B27/28
Filed: 1991-04-26
Abstract: PURPOSE:To obtain the inexpensive optical isolator being suitable for light integration without adjusting expensive parts with high accuracy by constituting it so that cut-off of a TM mode exists between the respective phase constants of forward wave and a backward wave. CONSTITUTION:Phase constants are different from each other due to a difference of the advance direction of light guided along an optical waveguide 1 by a magnetizing vector in a magneto-optical material, cut-off of a TE mode becomes larger than cut-off of a TM mode due to structural anisotropy of the waveguide 1, and when cut-off of the TE mode exists between the phase constant of a forward wave and the phase constant of a backward wave, and a coupling coefficient from the TM mode to the TE mode due to optical anisotropy exists, the forward wave of the TM mode is not coupled with the TE mode due to mismatching of the phase but is guided as it is, and the retrograding wave of the TM mode is coupled with the TE mode of radiation and from a core of the waveguide 1, optical power is dissipated. Accordingly, an inexpensive optical isolator being suitable for light integration is obtained without adjusting expensive parts with high accuracy.

Title: Amalgam pellet for fluorescent lamp, and the fluorescent lamp using the pellet
Inventor: MATSUGAKI YOSHIHIKO
IPC: H01J61/24
Filed: 1999-02-27
Abstract: PROBLEM TO BE SOLVED: To keep an amalgam pellet which hardly releases mercury at room temperature and is hardly oxidized at room temperature by enclosing the amalgam pellet prepared by mixing tin and mercury at a specific atomic ratio in a discharge tube. SOLUTION: An amalgam pellet, wherein the atom ratio of tin to mercury is 90-80:10-20, is prepared. A pellet for a fluorescent lamp, provided by forming the amalgam into a diameter of not more than 3 mm, is enclosed in a discharge tube to form a fluorescent lamp. The amalgam is solid at room temperature, starts to melt at 160-179 deg.C, and melts completely at 210-220 deg.C. The amalgam hardly releases mercury even at 140 deg.C. Since the content of the mercury can be reduced, the dispersion of the mercury amount can be reduced, when used by forming it into a pellet. By using the amalgam, it will not be oxidized in the air, and the evaporation of the mercury can be minimized at room temperature, so that the fluorescent lamp can safely be manufactured at a low cost.

IPC: B29C33/58
Filed: 1987-04-22
Abstract: PURPOSE:To prevent sunken parts from developing on the surface of a cured molded product at the show-side surface by a method wherein a fluoroplastic film, which makes surface energy smaller, is formed on a core side surface in order to obtain a molded product. CONSTITUTION:The reaction injection molding concerned is to form a fluoroplastic film on the core side surface in a mold, when a cured polymer molded product is obtained by reaction injection molding by casting metathetically polymerizable monomer in a mold in the presence of metathetically polymerizing catalyst system. By employing the above-mentioned method, even when the difference is small between the temperature of the core side surface and that of a show side surface, almost no sunken part develops on the surface of the cured polymer molded product on its show side surface. Namely, under the notion that shrinkage may be possible to develop only on a surface side, if that side is made as non-tacky as possible, the fluoroplastic film is formed on the core side surface. Actually, the shrinkage occurs exclusively on the core side surface and a surface with no sunken part is easily obtained on the show side surface.
