Abstract: A normally closed disc clamp system includes a housing with a rotating disc, a brake ring and a pressure-enhancing ring arranged therein. When only a first chamber is supplied with fluid, the fluid pushes the brake ring to release the rotating disc. When only a second chamber is fed with fluid, the fluid pushes the brake ring to keep the rotating disc in the braking state, and pushes the pressure-enhancing ring to compress an elastic unit. The energy generated by the compression of the elastic unit acts on the brake ring through the fluid, so that the brake ring achieves a double pressurization effect. If the action of the fluid fails, the brake ring can still provide a braking effect to the rotating disc through the elastic unit to improve operational safety. Further, the present invention further provides a rotating table using the normally closed disc clamp system.

Abstract: A dual-rotor wing motor includes a sleeve separating an inner shaft from an outer shaft. An external bearing is independently coupled to a shaft cover while an internal bearing is independently coupled to the inner shaft, and thus the external bearing and the internal bearing independently bear a friction force due to the rotation of the respective single shaft, the heat generated by the friction force can be reduced and the lubricant cannot be easily evaporated. Accordingly, the service life of the dual-rotor wing motor of the present invention can be prolonged.

Abstract: A self-setting security guarding system and method for protecting against unauthorized access to data stored in a data processing apparatus, comprising setting various items used to guard data, wherein the items consist of protected areas with access control for data storage and access therein, authorized types of files with access controls, and access rules of safety regulations enabling the data processing apparatus to verify access to data contents stored therein or in the protected area thereof; and detecting access events of the protected area or types of files using the access control and generating a request for analysis when an access event is detected, and further analyzing whether the detected access event complies with the access rules and the analysis request to permit or deny execution of said access event depending on whether it complies or not with safety regulations.

Abstract: A data write/read auxiliary device and method for writing/reading data are provided. A data storage unit and a program storage unit are installed in the data write/read auxiliary device, wherein the program storage unit is for storing automatic execution program and protection program. When the data write/read auxiliary device is connected to a data processing device, the automatic execution program is executed for automatically executing programs stored in the program storage unit. The protection program is executed for executing an access process on data storage unit to judge whether driving a write/read head or not based on outcome of the access process when a file sharing software is executed for data downloading and uploading. Through the data storage unit as a buffer area of data before writing/reading data on a hard disk, the data write/read auxiliary device and method for writing/reading data can protect the hard disk.

Abstract: The present invention relates to a drive mechanism of an electrical bike which has a drive motor positioned at outer side of the front fork thereof. A power output shaft of the drive motor vertically extends from a gearbox and directly coupled with axle of the front wheel through a gear. The drive motor drives the front wheel into rotation so as to achieve the effect of an auxiliary or a full drive for the bike. Besides, the drive motor and related components are well distributed to the front wheel so that the loading of the rear wheel can be effectively reduced, thereby improving the control performance in riding.
