    Abstract: An enhanced electronic card structure includes a circuit board, a top cover board, and a bottom cover board. The circuit board has multiple front front and rear contact points. At least one fixing hole is defined between any two adjacent front contact points. The top cover board has a front edge defined therein multiple gaps, each aligned with one front contact point and corresponding rear contact point. Any two adjacent gaps are separated by a rib, each rib having a bottom face extended thereform a fixing tip aligned with the fixing hole. The bottom cover board has a surface formed thereon multiple fixing joints, each aligned with one fixing tip at the bottom of the rib, so as to make the fixing tip pass through the corresponding fixing hole to be fixed to the corresponding fixing joint.

    Abstract: A memory card casing includes a plastic framework, and upper and lower metal covers that could be conveniently assembled to two sides of the plastic framework. The metal covers are fastened to each other via fastening means spaced on perpendicular wall portions of the metal covers. Each of the fastening means includes first and second fastening plates. The plastic framework is provided with retaining means, each of which includes a neck portion inward projected from and perpendicular to inner wall surface of the plastic framework and an expanded head portion in front of the neck portion. When the two metal covers are closed onto two sides of the plastic framework, the second fastening plates are located in recesses defined by the first fastening plates with tongues provided on the first fastening plates extended through retaining holes defined by the second fastening plates to firmly hold the two fastening plates together, and the neck portions are confined in holes defined by spaces on the wall portions of the metal covers between any two adjacent fastening plates to prevent the expanded head portions and, accordingly, the whole plastic framework from separating from the closed metal covers.

    Abstract: Torque is generated by the rotating front road wheel of a motorcycle for balance. When the vehicle is traveling too slowly, too little torque is generated for adequate balance, and when the vehicle is traveling too quickly, too much torque is generated for safe maneuvering. A torque compensator for a motorcycle thus includes a sensor for detecting the angular momentum of the road wheel. The detected angular momentum is compared to a predetermined optimal angular momentum by a comparator. An electric flywheel attached to the steering fork of the motorcycle is driven at a variable speed to generate a compensating angular momentum equal to the difference between the angular momentum of the road wheel and the optimal angular momentum. When the angular momentum of the road wheel is below the optimum, the flywheel is driven in the same direction as the road wheel to provide supplemental momentum, so that the sum of their momentums is equal to the optimal angular momentum. When the angular momentum of the road wheel exceeds the optimum, the flywheel is driven in the opposite direction as the road wheel to provide a counteracting momentum, so that the sum of their momentums is still equal to the optimal angular momentum. Thus the combined torque of the road wheel and flywheel is always optimized for the best stability and steering response throughout the entire speed range of the vehicle.

    Abstract translation: 扭矩由摩托车的前轮转轮产生，用于平衡。 当车辆行驶太慢时，产生足够平衡的转矩太小，当车辆行驶太快时，产生过大的扭矩以进行安全的操纵。 因此，摩托车的扭矩补偿器包括用于检测车轮的角动量的传感器。 通过比较器将检测到的角动量与预定的最佳角动量进行比较。 以可变速度驱动连接到摩托车的转向叉的电动飞轮，以产生等于车轮的角动量与最佳角动量之间的差的补偿角动量。 当车轮的角动量低于最佳时，飞轮的驱动方向与车轮相同，以提供补充动量，使得它们的动量之和等于最佳角动量。 当车轮的角动量超过最佳时，飞轮以与车轮相反的方向被驱动以提供抵消动量，使得它们的动量之和仍然等于最佳角动量。 因此，车轮和飞轮的组合扭矩始终是优化的，以便在车辆的整个速度范围内实现最佳的稳定性和转向响应。

    Abstract: A vertical turbine comprising a blade control mechanism including a sun gear engaging a plurality of planetary gears each coupled to blade assemblies. The sun gear has at least half circumference of its teeth removed, as the turbine receives maximum downstream torque in the circumference with teeth and it leaves blades free to rotate in the circumference without teeth for minimum upstream drag. The turbine converts the rotational blades into parallel movement and unidirectional propulsion with minimum turbulence.
