Abstract

APARATO DE CINTA EN BUCLE SINFIN CON CONTROL DE TENSION DE PRECISION Y UTILIZACION EN COMBINACION UN DUPLICADOR DE CINTA DE VIDEO DE ALTA VELOCIDAD. APARATO DE CINTA EN BUCLE SINFIN CON CONTROL DE TENSION DE PRECISION PARA UTILIZAR CON UN DUPLICADOR DE CINTA DE VIDEO DE ALTA VELOCIDAD, TAL COMO UN SONY SPRINTER, QUE INCLUYE UNA CAJA DE ALMACENAMIENTO DE CINTA MAESTRA PARA ACUMULAR Y ALMACENAR UNA LONGITUD DE CINTA DE VIDEO MAESTRA EN FORMA DE BUCLE SINFIN PARA DUPLICACION REPETIDA SOBRE UNA CINTA DE COPIA ALIMENTADA POR UN DUPLICADOR DE CINTA DE VIDEO. CONTROLADORES DE TENSION, TALES COMO COLUMNAS DE VACIO, ALIMENTAN LA CINTA MAESTRA CON UNA TENSION ALTA CONSTANTE PREETERMINADA AL DUPLICADOR DE CINTA DE VIDEO. CINTA DE GUIA SE EMPALMA A LA CINTA MAESTRA Y SE EMPLEA PARA CARGAR LA CINTA MAESTRA EN LOS MEDIOS DE ALMACENAMIENTO DE CINTA MAESTRA Y EN EL DUPLICADOR DE VIDEO. UN IONIZADOR NEUTRALIZA CARGAS ESTATICAS EXISTENTES SOBRE LA CINTA MAESTRA Y EVITA LA NECESIDAD DE USAR CINTAS DE LIMPIEZA. LAS COLUMNAS DE VACIO PARA CONTROL DE LA TENSION EVITAN LA NECESIDAD DE USAR UNA CINTA DE ACCIONAMIENTO PARA TIRAR DE LA CINTA MAESTRA Y DE LA CINTA DE COPIA A TRAVES DEL TAMBOR DE TRANSMISION DEL DUPLICADOR.WINDOW LOOP DEVICE WITH PRECISION TENSION CONTROL AND USE IN COMBINATION A HIGH SPEED VIDEO TAPE DUPLICATOR. WINDOW LOOP TAPE APPLIANCE WITH PRECISION TENSION CONTROL FOR USE WITH A HIGH SPEED VIDEO TAPE DUPLICATOR, SUCH AS A SONY SPRINTER, INCLUDING A MASTER TAPE STORAGE BOX FOR STORING A LENGTH OF A LENGTH MASTER IN THE FORM OF AN ENDLESS LOOP FOR REPEATED DUPLICATION ON A COPY RIBBON FEED BY A VIDEO RIBBON DUPLICATOR. VOLTAGE CONTROLLERS, SUCH AS VACUUM COLUMNS, FEED THE MASTER TAPE WITH A CONSTANT HIGH VOLTAGE PRE-TERMINATED TO THE VIDEO TAPE DUPLICATOR. GUIDE TAPE IS PUT ON THE MASTER TAPE AND IS USED TO LOAD THE MASTER TAPE IN THE STORAGE MEDIA OF THE MASTER TAPE AND IN THE VIDEO DUPLICATOR. AN IONIZER NEUTRALIZES EXISTING STATIC LOADS ON THE MASTER TAPE AND PREVENTS THE NEED TO USE CLEANING TAPES. VACUUM COLUMNS FOR TENSION CONTROL PREVENT THE NEED TO USE A DRIVE TAPE TO PULL THE MASTER TAPE AND THE COPY TAPE THROUGH THE DUPLICATOR TRANSMISSION DRUM.
