PURPOSE:To decrease the number of parts, to reduce the size and to simplify the structure by providing the receptacle of optical parts connectable with an optical fiber cable and a male or female screw structure to a holder for fixing a light emitting or a photodetecting element, and using a stopper in common use as an attachment base. CONSTITUTION:This structure consists of the receptacle 1 which...

PURPOSE:To take in and out easily a specific optical fiber core, by holding a holding material, which is fixed pivotally to a holding material storing box body freely turnably, so that this holding material can be taken in and out on one opened face of the holding material storing box body. CONSTITUTION:Fixing tools 10 and 11 are provided on a side plate 6 of a holding material storing box body 2 ...

PURPOSE:To prevent the end face of a fiber from being injured and improve the operability of fiber connection, by providing positioning means, which consist of hemispherical projections and recessed parts to be fitted to these projections, on the face of a ferrule abutted on a receptacle. CONSTITUTION:An optical fiber 3 is inserted to a fiber insertion hole 2a of a ferrule 2, and a clamp screw 10 ...

PURPOSE:To fix an optical fiber to a ferrule without tools for exclusive use by forming a flexible piece, which is divided by slits and has a thread, on a fiber insertion hole of the ferrule and engaging a clamp screw with this thread to constrict the insertion hole uniformly. CONSTITUTION:A flexible piece 2b which has an inclined thread 9 and is divided to plural pieces by slits 8 is formed on a ...

PURPOSE:To hold down the connection loss in the connection part of an optical cable to a low value, by allowing the end face of the connection part of the optical cable, to which a ferrule is fitted, to oppose to the outside circumferential face of a drum and interposing grinding particles between them and moving the optical cable relatively in the direction parallel with the lengthwise direction ...

Disclosed is an improved method of fabricating boron fiber and aluminum matrix composite structures, especially gas turbine compressor blades having titanium metal skins. Titanium skins and boron aluminum composite cores are preformed by gas pressure and hard dies prior to hot pressing. The composite sheets of the core are preformed with the use of expendable carrier sheets, which hold the stacked...

IL SERT A REALISER UN MODELE FONCTIONNEL AVEC UNE MAQUETTE D'OCCLUSION ET IL CONVIENT EN PLUS POUR CONFECTIONNER, EN COMBINAISON AVEC UN MATERIAU DE REMBOURRAGE ADEQUAT, UN PROTEGE-DENTS POUR SPORTIFS. L'INVENTION CONCERNE...

A radiation-tight coupling arrangement for coupling a machining laser to a hot cell containing radioactive material, comprising a cell flange integrally formed on the confinement wall which defines a cell opening, a cell door formed to interlock tightly with the cell flange, thereby closing the cell opening, an elongated container movably arranged in the sleeve and having a container flange defini...

L'INVENTION CONCERNE UN SYSTEME POUR LA CONCEPTION ASSISTEE PAR ORDINATEUR D'ARTICLES, TELS QUE DES VETEMENTS, ET QUI COMPORTE : UNE UNITE DE COMMANDE 16 AYANT DES CAPACITES DE MEMOIRE ET DE TRAITEMENT APPROPRIEES POUR MEMORISER ET CLASSER UNE MULTITUDE D'ELEMENTS CONSTITUTIFS DESDITS ARTICLES; UNE UNITE DE RECHERCHE ET D'AFFICHAGE QUI COMPORTE DES MOYENS 20 POUR EXTRAIRE LES ELEMENTS DE LA MEM...

PURPOSE:To surely know the projected position of a mold-finished lead frame to be treated by a method wherein a laser light ray from a laser light source is made to deflect by using a reflection mechanism and thus to pass through the proximate upper part and the side part of an object to be detected, and the passing light ray is detected by a photoreceptor. CONSTITUTION:A cutting treatment part 12...

PURPOSE:To grow any immobilized microorganism almost uniformly and make it possible to carry out the stable continuous fermentation for a long term, by carrying out the fermentation while transferring the immobilized enzyme to one end of a flow path for the fermentation liquor, and returning the immobilized enzyme to the other end of the flow path. CONSTITUTION:The fermentation is carried out whil...

PURPOSE:To prevent the mixing of air into a necessary gas by the curtain action of an inert-gas flow, to form a ball of the high degree of vacuum and to improve bondability by forming a section on the capillary intruding side of a shield cylinder in double structure and flowing an inert gas to the inside. CONSTITUTION:A bonding head 11 is loaded on an XY table 10, one end of a bonding arm 12 is su...
