Abstract: A three-phase uninterruptible power system and an operation method thereof are provided. The three-phase uninterruptible power system comprises a DC bus, three power conversion circuits and a control circuit. When the three-phase uninterruptible power system enters a line mode from a battery mode, the control circuit performs a huge current suppression for each power conversion circuit according to a predetermined sequence. The huge current suppression performed for any of the power conversion circuits comprises the following steps: disabling the DC-DC conversion of the power conversion circuit, and having the other two power conversion circuits to additionally share the original load of the disabled power conversion circuit; and after the DC-DC conversion of the power conversion circuit is disabled, enabling the AC-DC conversion of the power conversion circuit, and having the power conversion circuits revert to their original load.

Abstract: A thin film transistor includes a substrate, a semiconductor layer, a gate insulating layer, a gate, a source and a drain. The semiconductor layer is located above the substrate. The gate insulating layer is located above the semiconductor layer. The gate is located above the gate insulating layer and overlapping with the semiconductor layer. The gate includes a first portion, a second portion and a third portion. The first portion is extending along the surface of the gate insulating layer and directly in contact with the gate insulating layer. The second portion is separated from the gate insulating layer. Taking the surface of the gate insulating layer as a reference, the top surface of the second portion is higher than the top surface of the first portion. The third portion connects the first portion to the second portion. The source and the drain are electrically connected to the semiconductor layer.

Abstract: A speaker buffer structure includes an inner ring, an elastic outer ring, and an elastic bridge. The elastic bridge is connected between the outer peripheral edge of the inner ring and the inner peripheral edge of the elastic outer ring. The outer periphery of the elastic outer ring has a side groove. The side groove is used to connect to a through hole of a retaining tab of a sound box. The elastic bridge absorbs vibration from the speaker to improve the damping effect to limit transmission of vibration to an electronic device containing the speaker.

Abstract: An automatic setting method for ATM network is used in an information device for automatic connecting to an ATM network of an ISP office. At first an automatic configuration table is provided and includes a plurality sets of setting parameters of virtual path identifier (VPI)/virtual channel identifier (VCI) and encapsulation capacity for a plurality of default ISP offices. A user tries connection to the ISP office by selecting one set of the setting parameters as a connecting parameter to the ISP office and receives a reply message from the ISP office. The user selects another one set of the setting parameters as a connecting parameter to the ISP office when the connection fails and tries again until the connection to the ISP office successes.

Abstract: A method regulates a connection of at least one computer to Internet through a network-regulating apparatus. At least one supervisor logs in a computer connected to the network-regulating apparatus and sets a user attribution for at least one user in the network-regulating apparatus. The supervisor is authorized to create new user, delete user and edit user data. The supervisor also can set accessible time per day, accessible time per week for user, or unlimited time for user. The supervisor can set up certain keyword to examine the address and content of a website to identify the accessibility of a website. When a user accesses Internet for the first time, the user logs in the network-regulating apparatus and accessing Internet according to the user attribution set in the network-regulating apparatus.
