| 20090286576 | METHOD FOR CONTROLLING POWER IN DUAL-STANDBY MODE MOBILE TERMINAL AND APPARATUS THEREOF - The present invention relates to a method for controlling a transmission power of a dual standby mode mobile terminal. A method of controlling a transmission power of the invention includes performing a conversation standby service with a first communications network while performing a conversation service with a second communications network, and receiving a first power control level from a base station of the first communications network; comparing a second power control level that corresponds to a power code, which is set for a current output signal power, with the first power control level; and decreasing a current power code when the first power control level is greater than or equal to the second power control level. | 11-19-2009 |

| 20100064970 | APPARATUS AND METHOD OF FORMING SEMICONDUCTOR DEVICES - An apparatus to form semiconductor devices includes an inner tube and an outer tube disposed to surround the inner tube. A plate is disposed at first open end of the inner tube to reduce variation between pressures at a first portion and a second portion inside the inner tube. The sum of areas of through-holes disposed on the plate is 10 to 60 percent of the entire area of the plate. The through-holes may include a first through-hole that is disposed at a central portion of the plate, and second through-holes disposed at an edge portion of the plate. The second through-holes are annularly arranged to surround the first through-hole. | 03-18-2010 |
