Patent number: 7683522Abstract: A composite mode transducer for dissipating heat generated by a heat generating element is disclosed. The composite mode transducer includes a transducing module and connection elements. The transducing module includes first and second transducing elements connected in parallel. The connection elements are connected to resonance nodes of the first and second transducing elements. The first and second transducing elements are driven by a multiple-frequency resonance circuit, to produce resonance vibration of composite modes at resonance vibration frequencies of the system. The resulting advantages by using the composite mode transducer are: elimination of local stress concentration, and enhancement of efficiency, endurance and stability of the system. Accordingly, drawbacks of the prior art are overcome. The present invention further provides a cooling device with the composite mode transducer.Type: GrantFiled: February 11, 2008Date of Patent: March 23, 2010Assignee: Industrial Technology Research InstituteInventors: Syh-Yuh Cheng, Yun-Tien Chen, Ra-Min Tain, Shu-Jung Yang

Patent number: 5504384Abstract: A type of piezoelectric transformer (PT) which vibrates in length extensional mode is provided. The piezoelectric transformer (PT) has a piezoelectric substrate which has a first dimension, a second dimension and a third dimension with the first dimension being longest and the third dimension being shortest. The substrate has two polarization directions parallel to the first dimension near two terminals of the first dimension and at least two opposite polarization directions on a central portion of the substrate transversely to the first dimension. The substrate further has at least two electrodes on a portion horizontal to the first dimension. Comparing with traditional piezoelectric transformers, the new one can solve the polarization difficulties and reduce audio noise output without sacrificing the electrical properties or even have better voltage transformation characteristics.Type: GrantFiled: November 21, 1994Date of Patent: April 2, 1996Assignee: Industrial Technology Research InstituteInventors: Yu-Lin Lee, Syh-Yuh Cheng, Yun-Tien Chen, Shu-Fen Liao, Wen-Chin Yeh

Patent number: 5263115Abstract: An improved PTC electric heating element assembly comprises a heating element of a ceramic material with positive temperature coefficient, two insulating elements with different thickness, and four metal sheets, which are arranged in a stack to firmly join together by a fastening means fixed on the bottom of a container. The opposite sides of the heating element are contacted by metal sheets having electrodes which are connected to electric wires to effectively conduct the heat produced to the container.Type: GrantFiled: September 25, 1991Date of Patent: November 16, 1993Assignee: Industrial Technology Research InstituteInventors: Pin-Win Kauo, Ching-Iuan Sheu, Yun-Tien Chen, Suh-Yuh Cheng

Patent number: 5045747Abstract: An apparatus for poling a piezoelectric ceramic includes a first and a second electrode which are connected to a DC power supply and spaced away from one another at a certain distance, and an insulated medium provided between the first and second electrodes. The second electrode is adapted to carry the piezoelectric ceramic which is spaced away from the first electrode. In this way, a piezoelectric ceramic can be poled by a poling field created between the first and second electrodes and prevented from being scraped by the first electrode or damaged by the ripples caused by an unstable voltage because of the separation of the piezoelectric ceramic to be poled from the first electrode and the buffering effect caused by the insulated medium between the first and second electrodes. In addition, the second electrode may be specifically in the form of a power-driven metal conveyor so that the piezoelectric ceramic to be poled can continuously pass through and be poled by the poling field.Type: GrantFiled: February 28, 1990Date of Patent: September 3, 1991Assignee: Industrial Technology Research InstituteInventors: Yun-Tien Chen, Syh-Yuh Cheng, Shu-Fen Liao
