Title: Adaptive signal processing method and system for antenna array
Inventor: AIKEN RICHARD THOMAS
IPC: H04B7/10
Filed: 2001-01-11
Abstract: PROBLEM TO BE SOLVED: To provide a method and a system for reducing processing resources related to the adaptive algorithm for an antenna array or processing time. SOLUTION: Antenna arrays 10 connected to a radio assembly 17 include a phased array 12 and a diversity array 14 alienated from the array 12. The assembly 17 gives an interface between a radio frequency signal, a microwave frequency signal, or the other electromagnetic signals composed of a signal whose frequency is higher than that of a base band signal and a base band signal whose frequency is lower than those of the electromagnetic signals. The assembly 17 also performs thresholding for providing different transmission signal path and reception signal path and amplifies the transmission signal path and the reception signal path. The assembly 17 is further connected to a signal processing system 15. The system 15 processes the baseband signal and improves the performance of downlink and uplink signals between a mobile station 19 and the assembly 17.

Title: Highly refining method for high purity metal and refining apparatus therefor
Inventor: TAYAMA KISHIO
IPC: C22B19/32
Filed: 2001-01-23
Abstract: PROBLEM TO BE SOLVED: To provide a highly refining method for a metal such as indium containing various impurity elements whose purification into a high degree has been difficult in the conventional technique, and a refining apparatus therefor. SOLUTION: Indium as a raw material metal having purity of 99.9% is charged to a raw material crucible 8, and is heated to 1,250 deg.C by an upper carbon heater 6 in a vacuum atmosphere in which the degree of the vacuum is 1×10-4 Torr (1.3×10-2 Pa). In this way, indium is evaporated and is condensed at the inside face of a inner cylinder 3, and is dropped and recovered to a liquid storage part 9 at the lower part of a cylinder 11. Impurity elements whose vapor pressure is lower than that of indium remain in the raw material crucible 8, and are separated. Next, the recovered indium in the liquid storage part 9 is heated to 1,100 deg.C by a lower carbon heater 7.  The vapor of impurity elements whose vapor pressure is higher than that of indium in the generated vapor passes through a diffusion board 12 made of graphite at the upper part in the cylinder 11, and is exhausted to the outside of the system. The indium vapor is contacted with the diffusion board 12, is recondensed, and returns to the liquid storage part 9, so that highly refined indium of 99.9999% can be obtained while preventing the loss of indium.

IPC: H04W56/00
Filed: 2001-01-25
Abstract: PROBLEM TO BE SOLVED: To provide a communication terminal and a synchronized capturing method by which cells are accurately searched at a high-speed. SOLUTION: A scrambling code identification section 115 sores a threshold value A and a threshold value B lower than the threshold value A and identifies a scrambling code whose correlation value exceeds the threshold value B. A cell search control section 120 omits frame synchronization confirmation processing to complete cell search when the scrambling code whose correlation value is greater than the threshold value A is identified. When the correlation value is greater than the threshold value B and equal to or less than the threshold value A, the cell search control section 120 controls a switch 103 to connect a wireless reception section 102 and a correlation processing section 116. A frame synchronization confirming section 119 confirms whether or not frame is synchronized.

Title: Magnetic disk device
Inventor: AKAGI KYO
IPC: G11B19/00
Filed: 2001-02-08
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a HDD incorporated in mobile PC and a portable information electric home appliance is damaged by falling and the like and that the spindle of the HDD is damaged by outer vibration and the like even at non-operation time. SOLUTION: When a recording/reproducing command or a seak command is not issued even in a state where a system is connected to a host device, possibility that the system is damaged can be reduced by fixing a movable part in the HDD for most of the time by providing a means for fixing a disk and a head to a electromagnetic latch. Thus, resistance to outer impact due to the drop of a mobile unit is high, the fault of the spindle by outer vibration at non-operation time can be avoided and therefore the loading rate of the HDD for mobile PC and the portable information electric home appliance increases.
