Patent number: 11333303Abstract: A hydrogen storage composition, a hydrogen storage container and a method for producing the hydrogen storage container are provided. The hydrogen storage composition includes a thermally-conductive material, a hydrogen storage material, and optionally a granular elastic material. The hydrogen storage container includes a canister body and the hydrogen storage composition.

Publication number: 20200335580Abstract: Methods for manufacturing a MOSFET device for high voltage application are disclosed to solve less-than-90-degree trench angle problem. In one embodiment, the trenches in a MOSFET device are filled with different concentrations of P? epitaxial material at different stages to improve charge balance. In an alternative embodiment, several N? epitaxial layers with different concentrations are created before etching trenches filled with P? epitaxial material. Yet in another embodiment, a reverse deep trench process creates a P? epitaxial layer first, and etches trenches to be filled with N? epitaxial and act as active region during device operation, leaving the remaining P? epitaxial columns as non-active regions. The final device structure of the remaining P? epitaxial columns is similar to the traditional P? epitaxial trenches.Type: ApplicationFiled: March 22, 2020Publication date: October 22, 2020Inventors: Haiping Dun, Hung-Chen Lin, Chi-Wu Yao

Patent number: 10532337Abstract: A container is disclosed. The container includes a canister body, at least one heating device and at least one safety device. The canister body includes an inner space for storing a gas storage material. The at least one heating device is accommodated within an inner space of the canister body for heating the gas storage material, so that the gas storage material releases a gas. The at least one safety device is connected with the corresponding heating device and installed on an end part of the canister body. When a temperature of the inner space is higher than a predetermined temperature value or a pressure of the inner space is higher than a predetermined pressure value, a portion of the gas is released through the safety device.Type: GrantFiled: August 19, 2016Date of Patent: January 14, 2020Assignee: ASIA PACIFIC FUEL CELL TECHNOLOGIES, LTD.Inventors: Jefferson Y S Yang, Wu-Yao Wei

Publication number: 20100027444Abstract: A method and system for establishing a connection for a wireless network device is provided. It allows a station to send a trigger signal to a multimedia receiving device. Upon receiving the trigger signal, the multimedia receiving device is prompted to reply to the station with a response signal. Upon receiving the response signal, the station is prompted to clone an identity information of the multimedia receiving device as its own identity information. The station is then allowed to be connected with a wireless network access device. By this way, the time for cloning the identity information of the multimedia receiving device in the station can be shortened, thus the overall connection establishment time can be reduced after the wireless network device is restarted.Type: ApplicationFiled: April 29, 2009Publication date: February 4, 2010Applicant: RALINK TECHNOLOGY CORPORATIONInventors: Yi Lin, Wu-Yao Chuang
