    摘要: Un dispositif comprenant des sections séparées de transmission et de réception convertit un signal audio (10, 11) en un signal FM (à 50, 51), transmet (110) le signal FM par des lignes à courant alternatif et reconvertit le signal FM en un signal audio (360, 361) qui peut alors sortir par des haut-parleurs ou autres dispositifs. En transmettant le signal par des lignes à courant alternatif, on n'a plus besoin de fils de connexion de haut-parleurs ou d'autres dispositifs à la source du signal audio.

    摘要: An adapter for enabling the signals produced by one type of audio device, such as a compact disc player, to be reproduced by a cassette player, the latter having a conventional cassette deck. The adapter is comprised of a housing (12) shaped like a standard cassette and has a transfer head (40) arranged to contact the playback head (50) of the cassette player. A jack plug (44) is connected to the transfer head (40) via a lead (42) which passes through a slot (46) in the housing. In use, the jack plug (44) is connected to a headphone socket of the compact disc player, and the resulting output can be heard from the cassette player.

    摘要: A simple and inexpensive demagnetizer for the magnetic heads (20) of a tape cassette recording and/or reproducing device includes an intermediate gear (36) which is rotated by either one or two hub gears (32, 34) engaging respective drive spindles of the recording and/or reproducing device. A push-pull rod (46) has one end pivotally connected to an outer radial position of the intermediate gear (36) and another end pivotally connected to a source (44) of alternating magnetic field of constant intensity. Rotation of the inter­mediate gear (36) causes the magnetic field generator to be cyclically and linearly reciprocated with respect to the head (20) so as to produce a decreasing magnetic field at the head.

    摘要: Lorsque l'appareil de nettoyage (11) permettant de nettoyer les têtes (32) de lecteurs/enregistreurs sur bande magnétique est chargé de manière opérative dans le lecteur/enregistreur, le mouvement du rouleau pinceur (36) et du cabestan (37) du lecteur/enregistreur fait tourner un élément de nettoyage (30) positionné contre la tête. La transmission du mouvement rotatif du rouleau pinceur et du cabestan est assurée par une courroie d'entraînement montée rotative (14) qui est reliée à un élément de nettoyage, tel qu'un patin en feutre, de sorte que, lorsque le rouleau pinceur et le cabestan tournent, la courroie est entraînée provoquant ainsi la rotation de l'élément de nettoyage contre la tête autour d'un axe sensiblement perpendiculaire au plan de la face de la tête du lecteur/enregistreur. Un assemblage de nettoyage d'une unité à bande magnétique permet de nettoyer le rouleau pinceur et le cabestan du lecteur/enregistreur lorsque l'appareil de nettoyage est à l'envers.
