Patent number: 7531883Abstract: A magneto-resistance transistor including a magneto-resistant element which may function as an emitter and a passive element which may function as a collector. The base may be interposed between the passive element and the magneto-resistant element, thereby coupling the passive element with the magneto-resistant element. A magnetic field of a given strength may be applied to at least a portion of the magneto-resistant transistor, the given strength determining a resistance in the at least a portion of the magneto-resistant transistor. Thus, by adjusting the given strength of the magnetic field, the resistance may be adjusted. Therefore, different emitter current inputs may be achieved with a fixed voltage. Further, a base current may vary with a controlled variation of the emitter current input.Type: GrantFiled: November 17, 2006Date of Patent: May 12, 2009Assignee: Industrial Technology Research InstituteInventors: Ying-Wen Huang, Chi-Kuen Lo, Yeong-Der Yao, Lan-Chin Hsieh, Jau-Jiu Ju, Der-Ray Huang

Patent number: 6753192Abstract: According to the method for preparation of ultrathin magnetic layer on semiconductor of this invention, a non-ferromagnetic metal buffer layer thinner than 40 ML is formed on the semiconductor substrate on which the magnetic layer is to be prepared. The thickness of the non-ferromagnetic metal buffer layer may be 0.5-9 ML, preferably 1-8 ML, most preferably 1.5-6 ML. Thereafter, the magnetic layer is formed on said non-ferromagnetic metal buffer layer. The thickness of the magnetic layer so prepared may be less than 40 ML, close to the limitation of ultrathin. Material for the non-ferromagnetic metal buffer layer is preferably a metal or metal alloy that is immiscible with the magnetic layer when the magnetic layer is formed on the buffer layer. In the embodiments of the present invention, the non-ferromagnetic metal is silver, while material of the magnetic layer is cobalt. This invention also discloses the magnetic structure so prepared.Type: GrantFiled: February 20, 2003Date of Patent: June 22, 2004Assignee: Academia SinicaInventors: Yeong-Der Yao, Jyh-Shen Tsay, Heng-Yun Nieh, Cheng-Shiu Yang

Patent number: 6047456Abstract: A method for designing an optimal bi-axial type of magnetic gear system that uses magnetic coupling for transmitting torque in order to be free from the defects caused by using a conventional mechanical gear system. A non-coaxial rather than a conventional coaxial type of magnetic gear design is considered for this invention. For the non-coaxial magnetic gear system, the size of torque will depend on the number of poles magnetized out of the strong magnetic material around the magnetic gear. Therefore, the optimum number of magnetized poles must be carefully selected for a set of specified conditions such that the largest torque can be obtained. An optimal magnetic gear system can be produced by the method in this invention.Type: GrantFiled: December 19, 1997Date of Patent: April 11, 2000Assignee: Industrial Technology Research InstituteInventors: Yeong-Der Yao, Chia-Ming Lee, Shyh-Jier Wang, Der-Ray Huang

Patent number: 6044737Abstract: A new type of stator design and arc shaping method that is used in a diametrically wound and diametrical air gap type of brushless motor. After arc shaping, the stator of this brushless motor has an external profile composed of a central arc and two modified arcs located on each side of the central arc. The central arc subtends an angle twice that of angle A and the modified arcs each has a radius r, both angle A and r are given by the following formulae: ##EQU1## Through arc shaping the stator, the cogging torque is lowered while a certain standard value for the torque constant is still maintained. Thus, the overall efficiency of the brushless motor is raised.Type: GrantFiled: December 29, 1997Date of Patent: April 4, 2000Assignee: Industrial Technology Research InstituteInventors: Yeong-Der Yao, Jain-Chang Wang, Chin-Po Liao, Der-Ray Huang, Chi-Mou Chao
