摘要： A normal-time drive cam groove extends from a drive cam specific point, which is defined as a specific point of the drive cam, toward one side in a circumferential direction of the drive cam. A groove bottom at the normal-time drive cam groove is sloped relative to one end surface of the drive cam such that a depth of the groove bottom continuously decreases from the drive cam specific point toward the one side in the circumferential direction of the drive cam. An emergency-time drive cam groove extends from the drive cam specific point toward another side in the circumferential direction of the drive cam.

摘要： At a drive cam slope groove, a groove bottom is sloped relative to one end surface of a drive cam such that a depth of the groove bottom continuously decreases from one side toward other side in a circumferential direction. At a drive cam planar groove, the groove bottom is parallel to the one end surface of the drive cam. A drive cam connection groove has: one end connected to an end of the drive cam slope groove located on the other side in the circumferential direction of the drive cam; and the other end connected to an end of the drive cam planar groove located on the one side in the circumferential direction. A slope angle of the groove bottom relative to the one end surface of the drive cam continuously changes from the one end to the other end of the drive cam connection groove.

摘要： The present invention relates to a linear drive (1), comprising a drive shaft (10) arranged along a longitudinal axis (X), at least two propulsion teeth (20), and at least one rack (30) having a plurality of teeth (31), wherein the propulsion teeth (20) can move in a stroke transversely to the longitudinal axis (X) and are drivingly coupled to the drive shaft (10) in such a manner that the at least two propulsion teeth (20) perform at least one cyclical stroke movement (21) in the course of one rotation (φ) of the drive shaft (10) and enter and exit the at least one rack (30) to generate a propulsion in the longitudinal axis (X), and wherein the cyclical stroke movement (21) of the at least two propulsion teeth (20) takes place with a phase shift (Δφ). In addition, the present invention relates to a longitudinal adjustment unit and to a motor vehicle having such a longitudinal adjustment unit.

摘要： The present invention provides a rotary shaft assembly applied to a novel clutch system that ensures a 100% torque transmission rate between an engine and a transmission in a vehicle system and can be commonly applied to conventional manual transmission vehicles and automatic vehicles. The rotary shaft assembly converts linear motion of one member to rotary motion of another member, using a combination of a protrusion and an inclined guide slot.

摘要： Disclosed are a telescopic assembly and an occlusion mechanism. The telescopic assembly includes a rotating shaft, a telescopic piece, and a connecting piece; two spiral orbits extending in an axis direction are disposed on the circumferential side of the rotating shaft, and the spiral orbits are rotatably intersected with each other and communicate on tail ends to form a closed orbit; the telescopic piece sleeves around the rotating shaft; the connecting piece is movably connected to the telescopic piece, and the other end of the connecting piece moves in a spiral orbit groove all the time during movement; and with the rotation of the rotating shaft, the connecting piece drives the telescopic piece to do reciprocating movement along an axis so that the automatic telescopic movement of the telescopic piece is achieved. The telescopic assembly pushes a first rocking bar and a second rocking bar to achieve an occlusion action.

摘要： An actuator assembly is provided for converting rotation into linear displacement including a linear fluid dispensing tube for linear displacement. Hemispherical lugs are monolithically formed on the linear member. A primary gear includes a central bore having helix grooves formed into a surface of the central bore. The helix grooves receive the hemispherical lugs so that each helix groove mates with a respective hemispherical lug to reduce friction, so that hemispherical lugs slide smoothly within the respective helix grooves. Linear projections are formed on the exterior surface of the dispensing tube and extend longitudinally along the dispensing tube. A projecting portion has an aperture for receiving and guiding the dispensing tube through the linear displacement. Mating grooves are formed on an interior of the projecting portion for receiving and guiding the linear projections, thereby preventing the dispensing tube from rotating during travel.

摘要： Apparatus is described for administering a substance to a subject. A vial contains the substance and a stopper is disposed within the vial and is slidably coupled to the vial. A first threaded element is (a) rotatable with respect to the vial and (b) substantially immobile proximally with respect to the vial during rotation of the first threaded element. A second threaded element is threadedly coupled to the first threaded element. At least a distal end of the second threaded element is substantially non-rotatable with respect to the vial, and the distal end of the second threaded element defines a coupling portion that couples the second threaded element to the stopper. The first threaded element, by rotating, linearly advances the stopper and at least the distal end of the second threaded element toward a distal end of the vial. Other embodiments are also described.

摘要： Mechanism for transforming rotating to reciprocating motion, or vice versa, comprising a first annular component (1) and a second annular component (3) coaxially located, the first beside the second, along a longitudinal axis (ΔA), wherein both are able to rotate around the longitudinal axis and to reciprocate along the longitudinal axis, wherein aide (A) of the first annular component (1) adjacent to the second annular component (3) is in continuous contact, in at least one point, with the neighbouring side (Γα) of the second annular component (3), such that the second annular component (3) is able to rotate relative to the first annular component (1) in continuous contact in at least one point with the adjacent side (A) of the first annular component (1), wherein the contacting sides are undulated surfaces (A, Γα), such that if the first annular component (1) and the second annular component (3) are forced into rotational motion relative to each other, remaining the same time in continuous contact, then every point of the undulated surfaces (A, Γα) will trace, relative to the other, an undulated trajectory and at the same will also execute, relative to the other, reciprocating motion.
