Patent TW-429273-B (TW)
Title: Method for feeding garnular silicon material, feed pipe used in the method, and method of manufacturing a silicon monocrystal
Inventor: NAGAI NAOKI
IPC: C30B15/02
Filed: 1997-02-01
Granted: 2001-04-11
Abstract: In a pulling apparatus operated according to the multi-pulling method or CCZ method, granular silicon material is first fed to a feed pipe from a feeder so as to form stagnation of the granular silicon material in the feed pipe. The feeding of the granular silicon material from the feeder to the feed pipe is repeatedly commenced and stopped so as to maintain the stagnation of the granular silicon material. The feed rate of the granular silicon material from the feeder to the feed pipe is increased with time until the feed of the silicon material is completed. This prevents abrasion of a coating or lining provided on the inner surface of the feeder and also prevents damage of the feeder. In a pulling apparatus operated according to the Czochralski method, after causing granular silicon material to stagnate in the feed pipe, the crucible is lowered or the feed pipe is raised, while the stagnation of the granular silicon material is maintained, so as to form an unmolten layer of the silicon melt. The unmolten layer is then melted, and the granular silicon material is fed onto the unmolten layer through the feed pipe while the stagnation of the granular silicon material in the feed pipe is maintained. Accordingly, silicon material can be recharged without damaging the crucible, so that productivity and manufacturing yield of silicon monocrystals can be improved.

Title: Method for determining the position of a mobile terminal in a CDMA mobile radio system
Inventor: KARIM JAMAL
IPC: H04W64/00
Filed: 1998-12-01
Granted: 2001-12-21
Abstract: A method and system for use in determining the position of a mobile terminal in a CDMA mobile communications system is disclosed, whereby a different than usual spreading code is used when TOA measurements are being performed, but information is allowed to be transmitted while those TOA measurements are being performed. In one embodiment, the length of the different spreading code used is equal to one symbol length. In a second embodiment, a mobile terminal uses a long spreading code and short spreading code prior to making TOA measurements. When TOA measurements are to be made, the serving base station orders the mobile terminal to change the spreading code by terminating the use of the long code and continuing use of the short code. Alternatively, when the TOA measurements are to be made, the serving base station orders the mobile terminal to substitute a second, predetermined short code for the long code being used, and to continue use of the first short code. The TOA measurements are then performed in at least three base stations, and the position of the mobile terminal is derived form this TOA information. The serving base station then orders the mobile terminal to resume normal operations using the long code.

Abstract: The invention includes a partially densified preform and a method for the densification of one or more porous preforms. The porous preform is heated in the precursor liquid at a temperature sufficient to decompose the precursor liquid and to deposit a first decomposition product of the precursor liquid within the preform. Heating of the preform is ceased in the precursor liquid prior to densifying to the surfaces of the preform, thereby forming a partially densified preform. The densification is completed by chemical vapor deposition in an atmosphere comprising a gaseous precursor that heat decomposes to a second decomposition product within the undensified portions of the preform. The partially densified preform includes a densified region within the preform. The densified region includes a deposited decomposition product of a precursor liquid decomposed by liquid densification. An undensified region of the preform is between the densified region and at least one surface of the preform.

Filed: 1999-03-15
Granted: 2001-02-11
Abstract: Surface defects in a reflection scan of a print made with visible light are corrected by using a scan of the print made with infrared light. In accordance with the present invention, surface defects in a reflection scan of an image consisting of pixels made with visible light are corrected by using a scan of the image consisting of pixels made with infrared light. This correction of surface defects is performed by first establishing for each pixel an upper and lower bound for defect intensity based on the infrared record. The corresponding visible pixel is then corrected by subtracting the combination of upper and lower bound resulting in a corrected pixel.
