    摘要： A mechanical converter of irregular bi-directional motion into continuous and consistent single direction motion through a system of gears, drive shafts, freewheels, and flywheel. The system works by transforming circular movement, both clockwise and counterclockwise from the input shaft into continuous rotation of an output shaft through the use of a pair of free wheels solidly connected to the input shaft which transfers the alternating motion, depending on the rotation of the input shaft, to two parallel secondary shafts.

    摘要： A rotator mechanism for rotating an elongate member in a pumping system includes a body member having a longitudinal body axis and a through-hole aligned with the body axis and configured to receive the elongate member. The rotator mechanism also includes a worm gear concentric with the body axis and a worm meshing with the worm gear. The rotator mechanism includes a lever configured to rotate the worm, and a clutch coupled between the lever and the worm and configured to cause the worm to rotate in a first direction when the lever moves in the first direction. Rotation of the worm causes the worm gear and the elongate member to rotate about the body axis.

    摘要： Valve system with rotary stepping actuator to actuate a valve stem. An actuator drive shaft is supported for stepwise rotation in clockwise and counterclockwise directions to impart rotation to a valve stem nut to axially move a valve stem to open and close valve flow trim. The drive shaft forms peripheral first and second slotted circular drive paths co-axially spaced from each other. The drive paths include outwardly-opening, circumferentially-spaced slots which are matched in number, size and spacing, but the slots in the first drive path are rotationally offset from the slots in the second drive path by a set fraction, for example one half of the slot spacing. Actuation assemblies provide separate forward and reverse actuation cycles to the drive shaft to incrementally rotate the drive shaft in predetermined angular increments (steps) set by the slot spacing. Due to the offset, a counter step in a direction counter to the direction of a directly preceding step rotates the drive shaft by an amount less than the predetermined angular increment, as determined by the set fraction. If the set fraction is one half, the counter step rotates the drive shaft by a half step, while the next following step in the same counter direction is a full step in the predetermined angular increment.

    摘要： A window body positioning mechanism of a non pull cord window blind includes two first transmission wheels, two transmission cords respectively connected with one ends thereof to the first transmission wheels, two second transmission wheels meshed together and respectively meshed with the first transmission wheels, a coil spring connecting the two second transmission wheels and selectively wound round one second transmission wheel, and two resistance units each including a one-way pawl and a resistance wheel wound by one respective transmission cord and meshed with the one-way pawl. Thus, when extending out or receiving the blind body, the friction resistance between the resistance wheels and the transmission cords and the engagement relationship between the resistance wheels and the respective one-way pawls help achieve excellent blind body positioning effects.

    摘要： An image forming apparatus is provided. The image forming apparatus, in a case in which a toner on a transfer belt is checked through a sensing unit, is capable of preventing a rotation of a guide roller, which is configured to guide the transfer belt, by use of a regulation device, so that a check error occurring due to vibration of the guide roller is reduced. Thus, the toner on the transfer belt is checked with increased accuracy and precision.

    摘要： A reciprocating pedal transmission for a pedal-powered vehicle. Two pedals are selectively connected to a driveshaft by one way clutches. A reversing gear mechanism forces the non-pushing pedal to travel in a direction which is opposite to the direction of the pushing pedal. The non-pushing pedal may also be used to input force (a pulling force) if desired. The arcuate range of motion is infinitely variable. The user may reverse the pedal travel at any time using only the forces applied by the feet.

    摘要： A flow control valve controls the flow rate of heated water supplied from a boiler. The valve can normally/reversely turn and control the flow rate in a pipeline using first and second one-way motors, and stops power for one motor when the other motor is rotated. The valve includes a motor assembly including the first and second motors that have power transmission shafts which rotate in opposite directions, a gear assembly including first and second planetary gears that receive power from the motors and a sun gear disposed between and engaged with the planetary gears, a clutch structure between the first planetary gear and motor, and the second planetary gear and motor, that transmits or stops power, and a valve actuator including a shaft that reciprocates up/down by rotation of the sun gear and a valve unit fitted on the lower portion of the shaft that opens/closes the valve.
