Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a device for optical amplification suitable for wavelength division multiplex WDM and a system including the device where a gain characteristics is maintained constant to obtain a wide input dynamic range and power of a pump light is reduced. SOLUTION: An optical amplification device includes 1st and 2nd optical amplifiers 6, 8, and a controller 22. The 1st optical amplifier amplifies a received light. The 2nd optical amplifier receives the light amplified by the 1st optical amplifier and amplifies the amplified light. The controller 22 controls an attenuator 10 so that a level of the light received by the 2nd optical amplifier is changed nearly by -Δ when the level of the light received by the 1st optical amplifier changes by Δ. In one of various embodiments, the controller controls a sum of the gains of the 1st and 2nd optical amplifiers to be constant. In the other embodiment, the optical amplification device includes the 1st and 2nd optical amplifiers and a gain adjustment device.  The gain adjustment device adjusts the gain of the 2nd optical amplifier to compensate a deviation between the gain of the 1st optical amplifier and an objective gain.

Abstract: PURPOSE: To prevent occurrence of assembly failure and simplify assembly work by installing a joining part by which a plurality of push buttons are joined one another at the time of assembly and which is cut by pushing down work and makes the push buttons possible to be assembled independently after assembly. CONSTITUTION: In the case a cover 2 is fitted in a body 1, two push buttons 4, 4 are assembled while being mutually joined through a joining part 4c. On the completion of the assembly, operation parts 4b, 4b which are projected outside from the cover 2 are pushed in.

Title: Formation of multicolor fluorescent face
Inventor: HIGUCHI NAOATSU
IPC: H01J11/42
Filed: 1988-03-29
Abstract: PURPOSE:To easily form the multicolor fluorescent face with good accuracy even if the registration of monochromatic masks is not strictly executed (even if there are some deviations) by combining the full-color pattern and monochromatic masks formed on a transparent substrate, then exposing a photosensitive layer. CONSTITUTION:This method fixes the disposition of all colors first by the full-color pattern 3, superposes the monochromatic masks 5 for the respective colors thereon and exposes the same and, therefore, the deviations of the total pitch and the respective colors are determined only by the accuracy of the full-color pattern 3. The accuracy such as total pitch of the monochromatic masks 5 corresponding to the respective colors and the permissible range of the registration of the transparent substrate substrate 1 and the monochromatic masks 5 increase accordingly. The reason thereof lies in that the accuracy of the fluorescent face obtd. does not change in spite of some deviation in the registration, etc., of the monochromatic masks 5 if the light transparent parts 6 of the monochromatic masks 5 are formed slightly larger than the light transparent parts 4 of the full-color pattern 3. The multicolor fluorescent face having the extremely high accuracy is thereby obtd.
