  • Patent number: 10802551
    Abstract: A hinge mechanism includes a plurality of linkage units, each including a base bar and two rotating assemblies pivotally connected with two carrying sections of the base bar. Each rotating assembly has a synchronous rotation bar, a friction plate and a torsion plate. The friction plate has a first major plate body and a friction increasing portion inclined outwardly from the major plate body. The rotating assemblies are turnable relative to the base bar between unfolded and folded positions. During the turning, the friction increasing portion is gradually overlapped upon and in frictional contact with the torsion plate so as to increase a friction force for providing a stable turning.

    Abstract: A drive mechanism to move an optical component sensitive to particles is described. The drive mechanism has high precision in rotation, great reliability and durability life, no backlash, and far less particle contamination. The drive mechanism can be advantageously used in high precision rotation driving processes for opto-mechanical inspection systems that require high movement precision and no-contamination. In one embodiment, two pulleys are used with their axes to be parallel from each other, two bands are used to rotate the pulleys in opposite directions. An eccentric disk mechanism is used to fine-tune the distance between the two pulleys so that tensions on the two bands can be optimized.

    Abstract: An involute, non-ring, continuous teeth, spherical gear transmission mechanism includes a female and a male spherical gear to form a three degree-of-freedoms deputy campaign. And its design regularity is the same as that of common one degree-of-freedom gear, which is involute tooth profile for continuous engagement, therefore such spherical gears have the same transmission features as common one degree-of-freedom gear, like fixed transmission ratio and efficiency. This invention (utility) of involute non-ring continuous teeth spherical gear transmission mechanism solve problems that distributed-teeth spherical gear cannot provide accurate fixed ratio transmission and that spherical involute gear can only provide 2 degree of freedoms. It provides a better condition of spherical gear mechanism for wide use in practical engineering applications.

  • Patent number: 6336373
    Abstract: A drivig rotary shaft and a follower rotary shaft are rotatably carried in a housing of a rotary solenoid. Operating members fixed to the rotary shafts by clips are operatively connected to each other by gears, and a locked member is locked non-movably by locking surfaces formed at tip ends of the operating members. This makes it unnecessary to provide a device for converting a rectilinear motion to a rotational motion such as a pin and an elongated bore in a path of transmission of a driving force from the rotary solenoid to the operating members. Therefore, not only the number of parts and the number of assembling steps are reduced, but also the number of slide areas, where a friction resistance and looseness are liable to be produced, is reduced, thereby enabling a noiseless smooth operation.

  • Patent number: 5461325
    Abstract: An assembly suitable for use as an overclamp assembly is provided. The assembly includes a base having a shaft inserted therethrough. The shaft rotates about an axis relative to the base. A center block is pivotably coupled to the shaft for arcuate movement about the axis and relative to the base. A longitudinal drive assembly is inserted into the center block and coupled to the shaft. Rotation of the shaft causes the longitudinal drive assembly to traverse a longitudinal path and an arcuate path about the axis. The longitudinal drive assembly includes a holder which is suitable for attachment to a probe arm.

  • Patent number: 5444880
    Abstract: A manual CPR release for a hospital bed mechanically releases the head section from the head drive motor to quickly lower the head section to a flat position. When the head section reaches its lower limit, a switch is actuated which produces a command signal initiating the operation of both the head and knee drive motors. The knee drive motor lowers the thigh and foot sections to their flat positions and brings them into a coplanar position with the head section. Operating the head drive motor moves the head drive nut back into mechanical engagement with the head section.

  • Patent number: 5277076
    Abstract: Pivotal platform apparatus (10) includes a frame member (12), a platform member (14) being pivotally attached to the frame member and having a first rotational inertia, and a reaction member (20) being pivotally attached to the frame member and having a second rotational inertia. A pair of crossed taut elements (40a and 40b) provide means for transmitting reverse rotation pivotal movement between the platform member and the reaction member so that the inertia of the reaction member balances the reaction of the platform member to provide a reactionless scan mechanism. A pair of motors (26a and 26b), each having pole pieces (30a and 30b) attached to the reaction member, and each having motor coils (28a and 28b) attached to the frame member, provide means for rotationally positioning the reaction member.

  • Patent number: 5259262
    Abstract: A non-involute gear used in a gear pair. A first gear has a plurality of radially extending, circumferentially spaced teeth, each with a generally cylindrical, arcuate shaped end surface. A second gear has a plurality of spaced, non-involute shaped teeth. Each tooth of the second gear is formed with opposed base faces disposed at an identical radius. A pair of flats extend in parallel from the ends of each circular base face and terminate in inwardly extending, end portions extending from the flats to the top land of each gear tooth. A tooth space is formed between two adjacent non-involute gear teeth having a semi-circular base portion formed by the opposed circular base faces of two adjacent gear teeth and two parallel flat portions formed by the pair of parallel flats extending from the semi-circular base portion which combine to form a generally U-shaped space for receiving a gear tooth on the first gear.

  • Patent number: 5218876
    Abstract: A control device for a tiltable mounting head, such as the mounting head for a camera, has a three element pantographic linkage including a rigid control arm of which an intermediate point is constrained to move along a horizontal path. One end of the arm is pivotally mounted to an arm carrying the tiltable head, while the other end is pivotally mounted to a locating arm whose remote end is pivoted to fixed structure. The relative angular position of the two arms is controlled by two parallelogram linkages with different degrees of fold and having the central arm in common, whereby one of the two linkages is always laterally spaced from the arm. Alternatively the two arms may be secured to respective sprockets pivoted to the arm and connected together by a chain.

  • Patent number: 5180276
    Abstract: An articulated arm transfer device employs a rhomboidal link structure defined by two separated pairs of forearms pivotally joined at the elbows and at the wrists. Each wrist supports a holding structure and the elbows are driven in mirror-image semicircular paths by a pair of upper arms which are superimmposed alternately under each pair of forearms as the upper arms are rotated about mutually adjacent shoulder joints. The motion is such that at any time one holding structure is moving rapidly between an extended position and a park position while the other holidng structure is slowly traveling a negligible distance between a park position and a retracted position.
