Publication number: 20240017221Abstract: A mineral spring generator has a machine body and a pipeline disposed in the machine body. Two ends of the pipeline respectively have a water inlet and a water outlet. A solenoid valve is connected between the pipeline. At least two injection channels are connected to the pipeline at intervals along a direction of a water flow in the pipeline. A micromotor is connected between each of the at least two injection channels. An outer end of each of the at least two injection channels is connected to a material container. Each material container is adapted to be filled with a liquid mineral spring concentrate. When the present invention is used, water is inputted through the water inlet, and the solenoid valve and the micromotors are activated to add the mineral spring concentrates in the at least two material containers to different positions of the pipeline.Type: ApplicationFiled: July 13, 2023Publication date: January 18, 2024Applicant: National Taipei University of TechnologyInventors: CHI-CHUAN PENG, CHEN-CHING TING, TZU-CHIAO LIN, HO CHANG

Publication number: 20210186795Abstract: The present disclosure relates to a cervical spine traction device, equipment and method, wherein a built-in program code determines a cervical spine stretching force according to a sensed weight of a user. The cervical spine traction device has a main controller, a fixing unit, a movable unit and thermal massage units. By storing the program code in the main controller, the optimal traction data comprising a cervical spine stretching distance, the cervical spine stretching force and a cervical spine stretching time can be calculated according to the weight and height of the user lying down on the platform. Further, by sensing the temperature of the neck of the user and massaging the neck, the tension force of the neck muscle can be relaxed, the tightness of the user can be sufficiently eliminated, and the cervical spine of the user is corrected.Type: ApplicationFiled: December 19, 2019Publication date: June 24, 2021Inventors: HO CHANG, WEI LEE LI

Patent number: 10683454Abstract: The present invention relates to a phosphor, a method for preparing the phosphor, an optoelectronic component, and a method for producing the optoelectronic component. The phosphor has the following general formula: La3(1?x)Ga1?yGe5(1?z)O16: 3xA3+, yCr3+, 5zB4+, where x, y, and z do not equal to 0 simultaneously; A represents at least one of Gd and Yb; B represents at least one of Sn, Nb, and Ta. For the phosphor, its emission spectrum is within a red visible light region and a near-infrared region when excited by blue visible light, purple visible light or ultraviolet light; and it has a wide reflection spectrum and a high radiant flux. Therefore, it can be used in optoelectronic components such as LEDs to meet requirements of current medical testing, food composition analysis, security cameras, iris/facial recognition, virtual reality, gaming notebook and light detection and ranging applications.Type: GrantFiled: October 19, 2018Date of Patent: June 16, 2020Assignee: Everlight Electronics Co., Ltd.Inventors: Veeramani Rajendran, Mu-Huai Fang, Ru-Shi Liu, Ho Chang, Kuang-Mao Lu, Yan-Shen Lin, Chieh-Yu Kang, Gabriel Nicolo A.

Publication number: 20060123988Abstract: A method of using pure oxygen in microbial fermentation processes and wastewater treatment processes, in which the pure oxygen is produced by a pressure swing adsorption (PSA) process from a gas mixture of air and unused oxygen-containing recycled off-gas from microbial processes which uses oxygen-containing gas in a liquid or gas state. When pure oxygen with a purity of more than 90% is used in microbial processes, microbial productivity can be about 5 times as increased as it is that in the conventional method using air with an oxygen content of 21%, and the volume of an active sludge tank in wastewater treatment processes can be reduced to at most ? of the volume as compared to the conventional method. Also, the off-gas from such pure oxygen processes has a high oxygen content of about 70-80%.Type: ApplicationFiled: February 3, 2004Publication date: June 15, 2006Inventors: Ho Chang, Seung Chang, Chul Ryu, Longan Shang

Publication number: 20050133194Abstract: The present invention concerns a cooling structure for a continuous variation transmission system of an all-terrain vehicle. Primarily speaking, it has an inlet conduit attached to the air inlet of the gearbox, with said inlet conduit extending in front of the engine until it reaches the below of the front mud guard, and an inlet box attached to the inlet conduit. An exhaust conduit is also being attached to the exhaust of the gearbox, with said exhaust pipe extending to the rear of the engine until it reaches the below of the rear mud guard, and an exhaust box is attached to the exhaust conduit. Both the inlet box and the exhaust box are placed above the tail of the engine exhaust conduit, and situated on the outer surface of the chassis. The inlet and exhaust box design prevents dust, dirt and water from entering the gearbox. Furthermore, the conduits are installed on the outer surface of the chassis to enable ease of assembly and maintenance, and to reduce the difficulty of installing other components.Type: ApplicationFiled: December 18, 2003Publication date: June 23, 2005Inventors: Tzu-Jung Lan, Ho Chang
