Title: Juncture of optical fiber cord and connecting member thereof
Inventor: KATAYOSE KOICHI
IPC: G02B6/255
Filed: 1989-05-01
Abstract: PURPOSE:To decrease the number of parts and the number of stages for the purpose of connection without impairing the flexibility of a code juncture by superposing and adhering the ends of the fibers of tensile fiber layers on both sides onto the juncture of optical fibers which are fixed after an internal sleeve having a tensile body is put thereon, or adhering the ends of the fibers to each other. CONSTITUTION:The leading ends of the tensile fiber layers 5 on both sides on the internal sleeve 11 of the juncture of the optical fibers put with the internal sleeve 11 having the tensile body on fusion-spliced bare fibers 3 are adhered in the state of extending the fiber layers 5 thereof onto the internal sleeve 1 by the hot melt adhesive agent or the leading ends of the tensile fiber layers 5 are joined to each other. An external protective coating sleeve 14 consisting of a heat shrinkable tube 15 is shrunk by heating and put across the cut ends of external protective coating layers 6 on both sides and is adhered by the heating thereof with a hot melt adhesive agent 16. The number of parts is decreased in this way and the efficiency of the connecting operation is improved without requiring the special consideration for bending in the boundary part of the juncture and the optical fiber cord 1.

Title: Heat shrinkable sealing sheet and sleeve structure and using method of sheet thereof
Inventor: ROBAATO II SUTEIIRU
IPC: B29C65/68
Filed: 1992-05-01
Abstract: PURPOSE: To securely protect ends of a winding sleeve in corrosive environment, humid environment and the like by applying a heat shrinkable soft sealing sheet with adhesive strips on both longitudinal ends on both overlapping ends of a heat shrinkable winding sleeve. CONSTITUTION: A rectangular soft sealing sheet 11 extended in the 12 direction is applied on overlapping parts of a soft heat shrinkable winding sleeve 16 having overlapping ends 16a, 16b. The sealing sheet 11 shrinks to the anti-12 direction by being heated, and thereby recovers the original dimension. Since this sealing sheet 11 is applied with strips 14 of a retaining adhesive adjacent to the longitudinal ends 16a, 16b, the sealing sheet 11 adhered to the ends 16a, 16b of the sleeve 16 attracts the ends 16a, 16b with the shrinking. The adhesive- free range between adhesive strips softens by heating to be welded on the ends 16a, 16b.

IPC: A01G9/00
Filed: 1980-08-20
Abstract: PURPOSE: To provide a film which can convert light in a short wavelength range into one having a longer wavelength with good weather resistance and is useful for agricultural use for controlling the growth of plants, by incorporating a specified perylene pigment into a transparent plastic.  
     CONSTITUTION: A perylene pigment of the formula (wherein Y is oxygen, -NR ; R is H, a 1W5C lower alkyl or phenyl group which may be substituted with lower alkyl, lower alkoxy or halogen ; n is 1W8) is incorporated into a transparent plastic. As said transparent plastic, a plymer having a solubility parameter of 9 or higher is preferred. When the solubility parameter of the polymer is lower than 9, the solubility of the pigment in the polymer is very low, fluorescence can not be observed and film becomes easily opaque. Thus, such solubility parameter is not preferred. Since the purpose of the use of the pigment is different from mere coloration, the pigment is used in an amount of 0.001W3.0wt%.

IPC: C25B1/34
Filed: 1978-09-18
Abstract: PURPOSE: To produce chlorine water having high concentation of effective chlorine, by adding water glass to aqueous solution containing NaCl and electrolyzing, and to stabilize and maintain the concentration of effective chlorine by adding water glass to chlorine water.  
     CONSTITUTION: When performing DC electrolysis of water containing NaCl, such as sea water, as electrolyte in an electrolytic tank, water glass is added to the electrolyte by 2W5g per 1 liter of electrolyte. By the action of the water glass, the volatilization of chlorine produced by electrolysis is inhibited, and the cathodic reduction reaction and chlorate generation reaction are also inhibited, so that chlorine water  at high concentration containing effective chlorine by thousands to tens of thousands of ppm may be obtained easily. Besides, by adding water glass to the chlorine  water after electrolysis, similarly, lowering of the concentration of the effective  chlorine may be prevented, so that the high concentration may be maintained for a  long period of time.
