Title (EN) CONTACTLESS DIRECTION CONVERTER AND METHOD FOR MANUFACTURING OPTICAL FIBER
(FR) CONVERTISSEUR SANS CONTACT DE DIRECTION ET PROCÉDÉ DE FABRICATION DE FIBRE OPTIQUE
(JA) 非接触方向転換器、及び、光ファイバの製造方法
Abstract:
(EN) The present invention reduces the frequency of contact of an optical fiber with a side face of a groove that guides the optical fiber in a contactless direction converter that converts the direction of travel of the optical fiber without contact. A guide groove (1043) that guides a bare fiber (11) has a bottom exhaust nozzle (1043a) formed on the bottom thereof and side exhaust nozzles (1043b) formed on side faces thereof. A fluid is expelled toward the inside of the guide groove (1043) from the bottom exhaust nozzle (1043a) and the side exhaust nozzles (1043b).
(FR) La présente invention réduit la fréquence de contact d’une fibre optique avec une face latérale d’une rainure qui guide la fibre optique dans un convertisseur sans contact de direction qui convertit le sens de déplacement de la fibre optique sans contact. Une rainure de guidage (1043) qui guide une fibre nue (11) présente une buse d’échappement inférieure (1043a) formée sur sa partie inférieure et des buses d’échappement latérales (1043b) formées sur leurs faces latérales. Un liquide est expulsé vers l’intérieur de la rainure de guidage (1043) depuis la buse d’échappement inférieure (1043a) et les buses d’échappement latérales (1043b).
(JA) 光ファイバの走行方向を非接触で転換する非接触方向転換器において、光ファイバを案内する溝の側面に対する光ファイバの接触頻度を低減する。ベアファイバ(11)を案内するガイド溝(1043)の底面には底面噴出口(1043a)が形成され、側面には側面噴出口(1043b)が形成される。底面噴出口(1043a)及び側面噴出口(1043b)のそれぞれからは、ガイド溝(1043)の内部に向かって流体が噴き出す。
