Abstract: L'invention se rapporte à un appareil d'enregistrement/reproduction magnétique tel qu'un magnétoscope, un enregistreur à bande audionumérique, et similaires. Un signal d'insertion est enregistré d'avance en tant que marque de position permettant d'effectuer une correction automatique du contenu d'un programme. La fréquence du signal d'insertion est sélectionnée dans une bande de signaux audio. Le signal d'insertion est enregistré en même temps que les signaux audio par multiplexage à division temporelle sur une piste audio auxiliaire (24) d'une piste magnétique (21). Une zone de silence est créée avant une région d'enregistrement de signal d'insertion, et on estime que le signal d'insertion est correct lorsqu'il est détecté par un filtre après détection de cette zone de silence. Un compteur (6) détermine le signal d'insertion en fonction de ce rapport de fréquence. Un signal de reproduction est divisé en blocs et le signal d'insertion est détecté à partir de la distribution de la fréquence. La présente invention permet d'améliorer le rendement de l'enregistrement et de la reproduction du signal d'insertion, de simplifier la structure de détection et d'effectuer une détection correcte.

Abstract: Apparatus (20) for splicing together opposite ends of a sheet (26) of material, such as a photoconductor, to form an endless loop includes a generally cylindrical drum (24) on which the sheet material is wrapped. The drum (24) has edge portions (24a, 24b) that can be adjusted relative to each other to vary the circumference of the drum, and the sheet (26) is wrapped on the drum (24) with opposite ends of the sheet being in overlapping relationship adjacent the edges of the drum. The drum edges are adjusted relative to each other while a sensor (30) detects the relationship between perforations (28) or other identifiable features on the sheet. When a predetermined relationship is obtained, the opposite ends of the sheet are bonded together to form an endless loop. The apparatus produces a loop that is cylindrical in shape with the pitch of the perforations (28) across the splice being equal to the pitch of the perforations in other portions of the loop.

Abstract: A compact ion mobility spectrometer (IMS) with increased sensitivity and resolution for detecting the composition of an unknown substance is disclosed. The IMS comprises a unitary cylindrical housing (42), inlet means (50, 57) for introducing sample gas, outlet means (52, 59) for withdrawing sample and drift gas, two high voltage electrodes, and a detector (70). The first electrode (60) is pulsed to inject sample ions through an opening located in a second electrode (67) which defines a drift region (90). The second electrode (67) is cup-shaped having an open end and is electrically biased to create a non-uniform electric field gradient across said drift region (90). The electric field in said drift region (90) is axial and radial resulting in an increase in ion drift velocity at the detector (70) and a corresponding increase in detected peak signal amplitudes thereby increasing resolution. A shorter drift region (90) and the absence of an aperture grid near the detector (70), which cause ion collisional losses, helps to increase IMS sensitivity. <IMAGE>
