Abstract: PURPOSE:To stabilize the excitation light levels of a fiber type optical amplifier having redundant structure by which excitation lights outputted by two excitation light sources having two amplifying mediums and two excitation light sources are synthesized, and then divided into two and put into the two amplifying mediums. CONSTITUTION:Excitation light waves outputted by excitation light sources 2a and 2b are polarized by wave polarization controllers 12a and 12b, and they are put into a wave sypthesizer and divider 8 in a polarized state meeting at a right angle with each other. After the polarization and synthesis, they are distributed and put into rare-earth doped optical fibers 1a and 1b through wavelength multiple wave-synthesizers and dividers 3a and 5b.

Title: Automatic change-over method for taken-up thread
Inventor: TAKAMOTO AKIHIRO
IPC: B65H65/00
Filed: 1992-10-30
Abstract: PURPOSE:To prevent winding up of thread completely by fixing a thread end cleanly to a package without adding any foreign matter to the package. CONSTITUTION:Simultaneously with changeover of a thread to a B2 side, a shield plate 12 is operated to separate a take-up side bobbin B2 from a fully taken-up bobbin B1. Since a bobbin holder 9 to support a package (p) is braked, and a thread end (y) is separated from the bobbin B2 by the shield plate 12 through the thread end (y) of the package (p) is floated by some length and rotated, the thread is not wound on the take-up bobbin side. Then immediately before the rotation of the package (p) is stopped, the thread end (y) touches a charged electrode 13a to add static electricity. The thread end (y) is attracted to the package (p) by electrostatic force to prevent it from being wound up onto the take-up side bobbin B2.

IPC: B60R21/261
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To exactly control the three expansion speeds of low speed, medium speed and high speed. SOLUTION: Breaking of a second blockade member 13 between a first chamber 3 and a second chamber 4 is divided into a first stage in which a part of a bottomed hole 13c is a little broken by the pressure of combustion gas introduced through a vent hole 11 from the first chamber 3 into the second chamber 4 by means of ignition of a first ignition means 8, and a second stage in which breaking is greatly performed by the pressure of combustion gas in the second chamber 4, which is increased when a second ignition means 14 is subsequently ignited. Thus, the difference between a single ignition mode caused by only a first ignition member 8, and a time difference ignition mode for igniting the first and second ignition members 8, 14 becomes clear. The variability in expansion is large, and the expansion speeds are exactly controlled.
