Publication number: 20240217348Abstract: An adaptive speed control system and method for adapting control of an electric motor under a changing load condition. A load torque observer determines a load torque value when the motor is operating at a constant speed, and the load torque value is used to adapt a torque. An inertia observer determines an inertia load value when the motor is operating at a changing speed, and the inertia load value is used to adapt a controller gain. An active disturbance input decoupler provides disturbance rejection when the motor is operating at a constant speed. An adaptive control switch switches the load torque observer between driving the inertia observer and driving the active disturbance input decoupler. The system may be configured for a multi-axis system in which multiple motors are each associated with a different axis of motion, and multiple adaptive speed control systems are each associated with a different motor.Type: ApplicationFiled: January 23, 2023Publication date: July 4, 2024Applicant: Nidec Motor CorporationInventors: Athanasios Sarigiannidis, Bo-Ting Lyu, Wei-Chieh Hsu, Shih-Chin Yang

Patent number: 8149194Abstract: A base structure is used for bearing a display. The base structure includes a support and a seat. The support is connected to a display at one end and detachably disposed on the seat at the other end. The support has a buckling member, and the seat has at least one slot. The buckling member is fitted on the end of the support disposed on the seat, and is rotatable between a release position and a clamping position relative to the support. The buckling member has at least one baffle. When the buckling member is at the release position, the support is detached from the seat by passing the baffle through the slot. When the buckling member is at the clamping position, the baffle and the slot form an angle, and the baffle and the seat have a retaining relationship so as to lock the support on the seat.Type: GrantFiled: December 1, 2009Date of Patent: April 3, 2012Assignee: AmTran Technology Co., LtdInventors: Yu-Ching Wu, Wei-Chieh Hsu

Publication number: 20110111608Abstract: A connector is mounted on a circuit board via its feet of the housing (and/or a frame's feet) mounted at a tilting angle to the circuit board, or via a wedge base of its connector body such that the signal pins and the opening of the housing extend along a direction at the tilting angle relative to the circuit board. An external connector may be plugged into the tilting-type connector at a tilting angle. The feet and signal pins of the connector may be mounted to the circuit board by use of surface mount device (SMD) technology or direct insertion. A plane may be further deployed on the top of the connector for being used by an SMD equipment.Type: ApplicationFiled: June 7, 2010Publication date: May 12, 2011Inventors: Min-I Chen, Yung-Hung Ho, Wei-Chieh Hsu

Patent number: 6776870Abstract: An apparatus for solving an edge exclusion problem when polishing a semiconductor wafer includes a rotatable polishing platen with a polishing pad attached to its upper surface. A polishing slurry is deposited on the upper surface of the polishing pad during polishing. Mounted above the polishing pad is a rotatable polishing head for holding a substrate. A non-rotary actuator assembly is coaxially oriented about the outer edge of the polishing head. A ditched ring is removably attached to the bottom surface of the actuator assembly. A multiplicity of conduit grooves are formed in the bottom section of the ditched ring that allows the polishing slurry to travel unimpeded beneath the rotating wafer. A reduced wall thickness at the bottom of the ditched ring is configured to displace wrinkles from the outer edge of the wafer to the outer periphery of the ditched ring. This solves the edge exclusion problem while permitting polishing slurry to pass under the wafer.Type: GrantFiled: February 12, 2002Date of Patent: August 17, 2004Assignee: Vanguard International Semiconductor Corp.Inventor: Wei-Chieh Hsu

Patent number: 6200207Abstract: The present invention relates to a dressing apparatus for conditioning and regenerating a chemical mechanical polishing (CMP) pad. More specifically, the invention relates to a diamond disc dresser that employs an air spraying assembly and radially arranged dressing tools to clean, flatten, and roughen the polishing pad. Each of the dressing tools points at a same radial angle but are not necessarily equidistantly separated. Furthermore, a debris collector is used to collect the micro-particles and other types of contamination after they are swept off the working surface of the polishing pad.Type: GrantFiled: November 1, 1999Date of Patent: March 13, 2001Assignee: Vanguard International Semiconductor Corp.Inventor: Wei-Chieh Hsu
