Abstract: A solar power brick includes an optical guide layer, at least one solar cell, at least one electrical connection line and an outer frame. The optical guide layer and the solar cells are provided in the outer frame to combine as an integrated body. The optical guide layer is provided at the central part of the outer frame, and the solar cell is provided between the optical guide layer and the outer frame. The optical guide layer with optical refraction is used to direct the incident light onto the solar cells at the lateral sides to convert incident light into electricity for supplying the electricity to the external devices. The present invention is appropriate for generating electricity and possibly applied to the field which needs the built-in power supply, thereby increasing the optical illuminated area and the received amount of light, improving the overall generating efficiency.

Abstract: An energy-saving billboard module includes a solar energy module, a billboard, a light-emitting element, a storage cell, and a controller, which are accommodated in an outer frame. The billboard is adhered on the solar energy module and has transparent patterns. A light sensor is disposed on a top of the outer frame for sensing the luminance of sunlight to generate a sensing signal. The solar energy module receives sunlight and generates an electric power to charge the storage cell for outputting another electric power. The controller and the light sensor are supplied with the electric power outputted from the storage cell. The electric power of the storage cell is controlled by the controller based on the sensing signal so as to enable the light-emitting element to generate an emitting light for irradiating onto the billboard, so that the patterns of the billboard can be displayed.

Abstract: An automobile transmission system, comprising a planet gear interposed between the output gear and the speed differentiator of a conventional transmission device, a gliding hood is provided additionally on the outer casing of said speed differentiator, by the dynamic steering capability of the planet gear, power transmitting on the output gear assembly may be delivered by the planet gear active in direct or reverse rotation, moreover, by the displacement of the gliding hood on the outer casing of the speed differentiator the power being transmitted by the planet gear in direct or reverse rotation may be delivered way to the speed differentiator, eventually as output by way of the output shaft on the output end on both sides of the speed differentiator, thus controlling the vehicle to move forwards or backwards, with the input gear and the output gear devoted solely to take charge of speed regulation without regard to direction of vehicle movement, forwards or backwards, thus making possible structural simplif

Abstract: A car transmission system which employs gear sets for transmission and is free from clutch mechanism. The transmission system mainly includes several driving gears which have increasing numbers of teeth and are sequentially inter-fitted on a driving shaft from inner side to outer side at intervals, and several driven gears which have decreasing numbers of teeth and are sequentially inter-fitted on a driven shaft from outer side to inner side at intervals. The driven gears are constantly engaged with the corresponding driving gears. The transmission spring members are controlled by a manually operated or automatically operated transmission controlling assembly and are respectively reciprocally independently moved between an engaging position where the power is transmitted and a disengaging position where the power is not transmitted, whereby the power of the driving shaft is sequentially transmitted to any of the driving gears.

Abstract: Disclosed herein is a full meshing gear type variable speed transmission using interlocked gear pairs of the driving and driven gears to transmit power from the mainshaft to the auxiliary axle housing. The mainshaft can only drive the first driving gear through the spiral springs to drive the rest of the other driving gears indirectly. Each spiral spring of the different gear is normally disengaged, when the rotational speed of the auxiliary axle housing is exceeding a set limit, the spiral spring will be engaged with its gears change shift by the automatic gravity type shifting assembly. Each driven gear will also transmit its own power thru the transmission mechanism. Each transmission mechanism allows the driven gear of the higher shift to rotate faster than the driven gear of the lower shift, thus the interlocked pair of gears will not disengage during shifting.

Abstract: The present invention is to make use of fully engaged gear sets to transmit engine power, by means of untwisting or twisting tight the springs in the gear sets to selectively lock up other gear sets for power transmission so as to form into several spaced driving transmission gear rations in proper sequence, such that shift operation can be made during continuously stepping on the accelerator. Through a microprocessor, the shift operation is efficiently performed according to the revolving speed of the engine so as to let the car engine produce maximum performance all the time.
