Patent number: 8217745Abstract: An inductor includes a base and a winding assembly. The base includes an outer frame, a middle part and a connecting part. The outer frame has a first upper surface. The middle part has a second upper surface. The connecting part is connected with the outer frame and the middle part and has a third upper surface. The connecting part, the outer frame and the middle part collectively define a receptacle. The winding assembly is accommodated within the receptacle. The second upper surface of the middle part is disposed at a higher level with respect to the first upper surface of the outer frame. A first height is defined by the level difference between the second upper surface and the third upper surface. A second height of the winding assembly is smaller than the first height, so that a fourth upper surface of the winding assembly is disposed at a lower level with respect to the second upper surface after the winding assembly is accommodated within the receptacle.Type: GrantFiled: July 28, 2010Date of Patent: July 10, 2012Assignee: Delta Electronics, Inc.Inventors: Ching-Hsiang Tien, Yu-Chin Chen, Ming-Cheng Li, Zhi-Liang Zhang

Patent number: 7481898Abstract: A Ti-6Al-4V-0.2O (Ti64) forged article is fabricated by forging a workpiece to make a forged gas turbine engine component having a thick portion thereof with a section thickness greater than 2¼ inches. The forged article is heat treated by solution heat treating at a temperature of from about 50° F. to about 75° F. below the beta-transus temperature of the alloy, thereafter water quenching the gas turbine engine component to room temperature, and thereafter aging the gas turbine engine component at a temperature of from about 900° F. to about 1000° F. The resulting machined gas turbine engine component has a 0.2 percent yield strength of from about 120 ksi to about 140 ksi at its centerline, and a 0.2 percent yield strength of from about 160 ksi to about 175 ksi at a location about ½ inch below a surface thereof.Type: GrantFiled: October 24, 2003Date of Patent: January 27, 2009Assignee: General Electric CompanyInventors: Peter Wayte, Ming Cheng Li

Patent number: 6464461Abstract: The steam cooling circuit for a gas turbine includes a bore tube assembly supplying steam to circumferentially spaced radial tubes coupled to supply elbows for transitioning the radial steam flow in an axial direction along steam supply tubes adjacent the rim of the rotor. The supply tubes supply steam to circumferentially spaced manifold segments located on the aft side of the 1-2 spacer for supplying steam to the buckets of the first and second stages. Spent return steam from these buckets flows to a plurality of circumferentially spaced return manifold segments disposed on the forward face of the 1-2 spacer. Crossover tubes couple the steam supply from the steam supply manifold segments through the 1-2 spacer to the buckets of the first stage. Crossover tubes through the 1-2 spacer also return steam from the buckets of the second stage to the return manifold segments. Axially extending return tubes convey spent cooling steam from the return manifold segments to radial tubes via return elbows.Type: GrantFiled: December 8, 2000Date of Patent: October 15, 2002Assignee: General Electric CompanyInventors: Ian David Wilson, Kevin Joseph Barb, Ming Cheng Li, Susan Marie Hyde, Thomas Charles Mashey, Ronald Richard Wesorick, Christopher Charles Glynn, Martin C.
