Title: Manufacture of rough mold material of master model
Inventor: SUZUKI IWAO
IPC: B29C33/40
Filed: 1986-12-12
Abstract: PURPOSE:To obtain a rough mold material of a master model of favorable mold release properties, by a method wherein a powder material layer is formed on the surface of a mold of a rough model and then is cured by casting a resin solution after formation of a film layer. CONSTITUTION:A powder material layer 8 and film layer 9 are formed as mold release layers between a rough model 1 and resin 3. As air is apt to be introduced into a polishing powder layer 8 which has become a powdery state, the rough model 1 and a rough mold material 5 of a master model is released easily from each other. There is polishing powder suitable for the powder material layer 8, in a forming procedure of the mold release layer. When the powder is mixed into water at a weight ratio of 2:1 and is applied to the rough model 1 with a brush, the polishing powder layer 8 is formed. When a water soluble adhesive agent diluted with water is applied onto the polishing powder layer 8 and is dried naturally, the film layer 9 which is thin, possesses hardness and holds its own form is obtained and a form of the film layer is not broken down even if epoxy resin is cast. When the epoxy resin 3 is dried by fixing a pipe frame 4 to the same, the epoxy resin 3 is solidified. This solidified article can be released easily from a mold at the polishing powder layer 8 and the rough mold material 5 of the master model is completed.

Title: Method for detecting fault point in optical fiber, optical-fiber machining method using this method and extending method of opgw
Inventor: MINAFUJI JUNICHI
IPC: G02B6/46
Filed: 1989-11-15
Abstract: PURPOSE:To detect the fault point in a moving optical fiber by moving a time-division sampling time in response to the moving distance of the moving optical fiber in time, and performing multiple averaging for signals at a stationary position in space. CONSTITUTION:When breakdown occurs in an optical fiber 1, a pulse signal P is inputted into the optical fiber 1 through a directional coupler 12 from a pulse light source 11 based on the command from a timing adjustor 17. The signal P undergoes Fresnel reflection at the wire breakdown part, and backward scattering light P' is returned. The returned signal P' is separated and extracted with the coupler 12. The signal is transduced into an electric signal through a photodetector 12. The signal passes through an amplifier 14 and undergoes time-division multiple averaging in an adding and memory device 15. The result is displayed on a CRT 16. In this optical- fiber fault-point detector 10, the timing of the adjustor 17 is moved in response to the moving distance of the optical fiber 1. Thus, the multiple averaging for the signals P' from the stationary fault position in space can be performed. Therefore, the fault point of the moving optical fiber can be accurately detected as if the fault point were the stationary point.
