Abstract: The present invention provides a data accessing system and a data accessing method. The method comprises: separately storing a (N×M)-bit digital data in L banks of a data storage module; utilizing a register module of a data accessing interface module to transmit data of a bank for L times in sequence, and to receive and latch the digital data included by a bank from the data storage module when transmitting data each time, until the (N×M)-bit digital data is totally latched in the register module; and utilizing a multiplex output module of the data accessing interface module to continuously select a M-bit digital data from the (N×M)-bit digital data registered in the register module, and input the M-bit digital data to a data retrieving device via M data transmission lines.

Abstract: An electromotive motorcycle arranged with a power system using a fuel cell is disclosed. The power system includes a fuel cell, a cool water box, and a hydrogen storage device. The fuel cell is arranged on a framework. The cool water box is arranged at a front area of the framework. The hydrogen storage device has a container body and a plurality of hydrogen storage cans. The interior of the container body has a plurality of joints for being connected with the hydrogen storage cans, a guide tube and control elements. A temperature retainer is disposed in the container body. Thereby, hot water from the fuel cell is firstly guided to the temperature retainer in the container body before being guided into the cool water box. Therefore, the power system using a fuel cell is arranged on the electromotive motorcycle so that the electromotive motorcycle is used in an optimum condition.

Abstract: The present invention is related to a rotary roller set directional control device, particularly to a rotary roller set device, which is characterized by a novel design wherein two opposite longitudinal positioning slots are positioned at the upper section of a pivotal shaft socket, a pivotal supporting arm with a U-shaped rocker of which the front end is provided with a suitable catch key extended downward. The rocker may swing downward to assemble with the upper section of pivotal shaft socket and insert the catch key in the positioning slot. An annular flange on the top edge of pivotal shaft socket is designed to decrease the contact area between the pivotal supporting arm and the pivotal shaft socket when rotating the pivotal supporting arm to change the catch direction of U-shaped rocker so as to lower the frictional resistance.
