Abstract: A cylindrical and rotatable resonating assembly, generally for use in electrostatographic applications. The resonating assembly is preferably positioned along a longitudinal axis generally transverse to the process direction of movement of a toner bearing member, for applying uniform vibratory energy thereto. The cylindrical form of the resonating assembly allows for rotation of the assembly while remaining in contact with the image bearing member to reduce frictional forces between a contact surface of the resonating assembly and the image bearing member which, in turn, reduces wear of the resonating assembly as well as the image bearing member. The resonating assembly may include a plurality of discrete individual resonator elements, each including a vibratory energy producing segment, such as a piezoelectric transducer, for generating vibratory energy and a waveguide segment coupled to the vibratory energy producing segment for transporting the vibratory energy from the transducer to the image bearing member.

Abstract: A disk holding device of a thin design is
provided which can positively hold disks of different
thicknesses, and also can automatically align the disk.
The disk holding device includes a plurality of claw-like
members, a center hub receiving the claw-like
members therein, resilient members which are received in
the center hub, and respectively urge the claw-like
members in a radial direction of a disk, a turntable for
supporting the disk thereon, a cone ring which is provided
at a lower side of the center hub, and is movable
along an axis of a spindle shaft and an urging
member urging the cone ring in a disk-unloading direction
away from an upper surface of the turntable. The
cone ring has a slanting portion for engagement with a
center hole portion of the disk, and each claw-like
member is received in the center hub in such a manner
that the claw-like member is slidable in the radial
direction of the disk, and is angularly movable in the
disk-unloading direction. With this construction, a
force, required for loading and unloading the disk, is
small, and therefore the deformation and strain of the
disk can be kept to a minimum. And, the disk holding
mechanism and the disk alignment mechanism can be
combined into an integral construction, thereby
achieving a thin design of the disk holding device.

Abstract: Ce dispositif permet de mesurer la traction d'une sangle (7) sans affecter cette dernière de manière permanente. Pour transporter des marchandises, on utilise couramment des réseaux de sangles pour fixer (attacher) la charge à un support et il importe d'appliquer une force de pré-tension appropriée pour obtenir un transport sûr, l'idée étant de vérifier cette force avant mais aussi pendant le transport. On y parvient avec un dispositif porté à la main pouvant être déplacé latéralement sur l'objet mesuré (7) depuis un côté, en effectuant la mesure après l'extraction d'un bras d'activation puis son retrait après utilisation, sans effet rémanent sur la fixation. Techniquement, l'activation force l'objet (7) à se courber sur des rouleaux (17, 18), ce qui implique l'action de la force recherchée, perpendiculaire à la sangle (7), qui est enregistrée, recalculée (étalonnée) et affichée. Pour donner une précision élevée, l'instrument est équipé de deux réglages de largeur, qui permettent un positionnement latéral exact de l'objet mesuré, et d'un dispositif réglable compensant la force sur la longueur libre de l'objet (7). Cet instrument comprend aussi un contrôle de puissance automatique doté d'un signal d'alarme intervenant quand la pile doit être changée.

Abstract: Tapis roulant omnidirectionnel constituant une surface sans interruptions sur laquelle une personne peut bouger. Ce tapis roulant est construit au moyen d'un ensemble de courroies (1, 2, 10) formant une boucle, créant chacune au moins une surface allongée et venant en butée l'une contre l'autre le long des bords allongés de ladite surface allongée. Un groupe de ces surfaces allongées définit la surface du tapis roulant. Cet ensemble de courroies (1, 2, 10) est lui-même disposé en boucle. Le déplacement de la totalité de l'ensemble des courroies autour de cette boucle déplace la surface du tapis roulant dans un sens. La rotation simultanée de toutes les courroies (1, 2, 10) constituant la surface crée un déplacement perpendiculaire au premier sens. La mise en application de ces deux composantes de déplacement permet de déplacer le tapis roulant indéfiniment dans tous les sens. On peut utiliser le retour de l'utilisateur afin de déplacer le tapis roulant dans le sens contraire, afin que l'utilisateur reste au même endroit, de même, un tapis roulant conserve le déplacement de l'utilisateur dans un sens au même endroit.
