20120240695POWER TRANSMISSION APPARATUS AND METHOD FOR CONTROLLING POWER TRANSMISSION APPARATUS - A power transmission apparatus includes a drive shaft, a driven shaft, a first transmission device, a first one-way power transmission mechanism, a second transmission device, a second one-way power transmission mechanism, and a controller. The first transmission device is to change power of the drive shaft. The first one-way power transmission mechanism is to transmit power changed by the first transmission device only in one direction to the driven shaft. The second transmission device is to change power of the driven shaft. The second one-way power transmission mechanism is to transmit power changed by the second transmission device only in one direction to the drive shaft. The controller is configured to change ratios of the first transmission device and the second transmission device. The controller is configured to make the ratio of the first transmission device larger than the ratio of the second transmission device.09-27-2012
20100199790GEAR UNIT WITH A LAG FUNCTION - The invention concerns a gear unit (08-12-2010
20100050794MODULATOR FOR SUPPORTING ARM OF REAR BICYCLE CARRIER - A modulator for supporting arms of a rear bicycle carrier comprises a support frame including a central post having two ends with which first and second supporting arms are connected; a ratchet holder integrally formed with or separately disposed on the connecting position of the central post, and including a plurality of inner teeth arranged around the internal periphery thereof; a connecting shaft inserted through the ratchet holder, on the two sides of an intermediate seat of the connecting shaft being mounted two ratchet members for engaging with the inner teeth of the ratchet holder; a control unit fixed on a predetermined position of the rear bicycle carrier for being rotated clockwise or counterclockwise to disengage at least one ratchet member from the inner teeth of the ratchet holder such that the first and second supporting arms can be adjusted toward a suitable angle relative to the central post.03-04-2010
20080223158Ratchet Reset Mechanism - A ratchet apparatus includes a first member, a rack, and a second member that is selectively movable in first and second directions with respect to the first member. A first pawl is mounted with respect to the first member and is biased into engagement with the rack. The first pawl and the rack are configured such that engagement of the first pawl with the rack prevents movement of the first pawl relative to the rack in the first direction. A second pawl is mounted with respect to the second member for movement therewith in the first and second directions. The second pawl is biased into engagement with the rack. The second pawl and said rack are configured such that engagement of the second pawl with the rack prevents movement of the second pawl relative to the rack in the first direction.09-18-2008

20090211384Engine-flywheel hybrid - An engine-flywheel hybrid in which the engine power is varied mainly by the frequency of power cycles, not by the power per power cycle. The flywheel absorbs the energy from the power cycles and delivers energy. The rotary stop start mechanism stops and starts a crankshaft efficiently with minimal energy loss. This is accomplished by varying the offset of a double crank four bar linkage. The invention allows an engine's flywheel to be quickly be brought up to speed in about a half of a revolution, followed by combustion, expansion, and stopped one revolution after starting. Further, utilizing offset, the engine crankshaft will turn faster than the input shaft when the piston is at top dead center, shortening the time of highest heat transfer, making the engine more efficient. Also, that when used as an auto engine, the part load efficiency would be near the maximum efficiency of the engine, nearly doubling the miles per gallon of the auto.08-27-2009

20080196521Linear Feedback Device for an Actuator - A linear feedback device for an actuator comprises: a coiling belt, a return gear wheel, a driven member, and a sensing feedback device. The sensing linear feedback device serves to feedback the displacement data of the driven member that is moveable along a predetermined rail after engaging with the return gear wheel. The return gear wheel is coaxial with the coiling belt, and the coiling belt unwinds or retracts along with the actuator and drives the return gear wheel to rotate. The gear ratio between the return gear wheel and the driven teeth is used to adjust the back and forth moving distance of the probe. The linear feedback device can be installed in a small external hanging type body and offer an absolute position sensing function while preventing the error accumulation.08-21-2008

20080314172DEVICE TO TRANSFORM RECTILINEAR ALTERNATING MOTION INTO INTERMITTENT ROTARY MOTION - The invention concerns a device for transforming alternating rectilinear motion into intermittent rotary motion, in particular for the command of indexed rotary tables. It comprises at least one fixed base element (12-25-2008
