Patent number: 9178295Abstract: The present invention provides a flexible printed circuit board having gold fingers, comprising a base sheet, a metallic layer and a protective sheet. The base sheet has a plurality of voids thereon. The metallic layer is provided on the base sheet, and has at least one plated through hole. The protective sheet is provided on the base sheet and the metallic layer to expose a portion of the metallic layer and the plated through hole. The flexible printed circuit board may electrically be connected to a conductive terminal of a rigid printed circuit board with one gold finger and electrically be connected to a system with another gold finger. The plated through hole has a function of heat conduction and soldering, and the voids of the flexible printed circuit board can provide a space for overflowing solder and heat dissipation.Type: GrantFiled: October 15, 2014Date of Patent: November 3, 2015Assignee: DELTA ELECTRONICS, INC.Inventors: Yu-Liang Lin, Wen-Ping Teng, Jie Li, Guang Yang, Wen-Yi Chien

Patent number: 8587909Abstract: A transient current suppression device, which is applied to a fan, includes a filtering circuit, a delayed turn-on circuit and a forcibly electrical discharging circuit. The filtering circuit outputs a first voltage signal and a first current signal according to a first power signal. The delayed turn-on circuit is electrically connected with the filtering circuit. The delayed turn-on circuit provides a first discharging path for the first current signal according to a second power signal after a delayed time and outputs a second current signal. The forcibly electrical discharging circuit is electrically connected with the delayed turn-on circuit and the filtering circuit. The forcibly electrical discharging circuit provides a second discharging path for the second current signal according to the first voltage signal. Hence, the transient current suppression device can suppress the transient current effectively and rapidly.Type: GrantFiled: March 11, 2011Date of Patent: November 19, 2013Assignee: Delta Electronics, Inc.Inventors: Chia-Huang Wu, Chia-Yuan Chang, Wen-Ping Teng

Patent number: 7852228Abstract: A fan system including a motor, a driving unit, and a detector is disclosed. The driving unit is electrically connected to the motor and generates a driving signal to drive the motor and a detection signal. The detector is electrically connected to an output terminal of the driving unit and receives a voltage signal and the detection signal. When the motor operates normally, the detector outputs an examined signal to the output terminal of the driving unit. When the motor operates abnormally, the driving unit asserts the detection signal, and the detector is controlled by the asserted detection signal to transform the examined signal to an alarm signal according to the voltage signal to detect the abnormal state.Type: GrantFiled: October 28, 2009Date of Patent: December 14, 2010Assignee: Delta Electronics, Inc.Inventors: Wen-Ping Teng, Ming-Lung Liu, Ming-Yen Lin, Yueh-Lung Huang

Patent number: 7570009Abstract: A control device of a fan system, which has at least one fan, receives a starting voltage. The control device includes a start controlling unit and a driving unit. The start controlling unit receives the starting voltage and outputs a start controlling signal according to the starting voltage. After a predetermined period, the start controlling unit stops sending the start controlling signal. The driving unit is electrically connected to the start controlling unit and the fan, respectively. The driving unit receives the start controlling signal for controlling the rotation speed of the fan.Type: GrantFiled: August 16, 2006Date of Patent: August 4, 2009Assignee: Delta Electronics, Inc.Inventors: Tsung-Jung Hsieh, Ming-Lung Liu, Ming-Yen Lin, Wen-Ping Teng, Yueh-Lung Huang, Ming-Shi Tsai
