Filed: 1998-07-30
Abstract: A ball screw device provided with a
screw shaft having on the outer peripheral
surface thereof a spiral ball rolling groove, a
nut assembly having a load region composed of
a spiral load rolling groove facing the ball
rolling groove of the screw shaft and a non-load
region connecting for communication start
and terminal ends of the load region with each
other to define an endless track for balls, and a
ball connecting body formed of a multiplicity
of balls rolling on the endless track of the nut
assembly and a connecting body for rotatably
holding the balls in an aligned state, wherein a
guide groove is formed in the endless track of
balls for guiding the connecting body of the
ball connecting body to the non-load region so
that the respective balls move the connecting
body in the load region and the connecting
body guides and moves the respective balls in
the non-load region of the endless track, and
leading portions are formed at least both end
portions of the non-load region near the load
region for guiding the connecting body along a
direction in which the balls moving in the load
region advance. Transfer of the balls between the load region and the non-load region in the endless track is made smoothly to achieve
smooth circulation of the balls.

Abstract: A telescoping hydraulic hoist formed from a non-corrosive material provides bearings and hydraulic seals about the bottom portion of each intermediate moving stage. The bearings and hydraulic seals are thus always maintained within the hoist and are not exposed to dust or particulate matter from outside the hoist. Air flows into and out of the air spaces between adjacent stages through air breathers. The hoist may also include variable length stroke limiters, and a cushion member which partially closes off the hydraulic inlet as the innermost stage is fully retracted to slow the hoist motion in the final stages of retraction.

Abstract: L'invention se rapporte à un codeur convolutionnel à rétroaction mettant en oeuvre un registre à décalage avec à la fois des structures de circuit sans rétroaction et à rétroaction pour traiter et coder une séquence d'informations de longueur fixe. Ce codeur est configuré, grâce à une sélection appropriée de ses coefficients de rétroaction, de manière à permettre un mode de fonctionnement en boucle. Ce fonctionnement en boucle signifie que l'état du codeur avant l'entrée du premier bit de données non codées est le même que l'état du codeur au moment de l'entrée du dernier bit de données non codées. On détermine l'état de départ du codeur en combinant linéairement les bits de données dans la séquence d'informations. On établit les combinaisons linéaires au moyen d'une matrice de sélection ou d'un vecteur de sélection qui est dérivé des coefficients de rétroaction du codeur.
