Title: Display substrate and liquid crystal display device having the same
Inventor: OH WEON-SIK
IPC: G09F9/00
Filed: 2002-04-12
Abstract: PROBLEM TO BE SOLVED: To provide a display substrate and a liquid crystal display device having the substrate. SOLUTION: A pad part formed on the display substrate has many via holes to expose the pad metal film. The width of the via hole is made smaller than the diameter of a conductive particle. When the width of the via hole is larger than the diameter of the conductive particle, the depth of the hole is made smaller than the diameter of the conductive particle. Therefore, driving failure by the pad part can be prevented and the deformation rate of the conductive particle can be kept to 20 to 60%, which can enhance the adhesion strength between the pad part and the circuit board.

Filed: 2002-05-16
Abstract: <P>PROBLEM TO BE SOLVED: To configure a resonator that keeps the resonance frequency of the resonator in almost a fixed state even when the temperature of the resonator fluctuates, and a device using the resonator.  <P>SOLUTION: When a microstrip resonator is constructed by forming, for example, a ground electrode 3 on the lower surface of a dielectric substrate 1 and a resonance electrode 2 on the upper surface of the dielectric substrate 1, parts around the end parts of the resonance electrode 2 have a tapered shape, wherein the closer the parts to the ends, the thinner the film thickness of the resonance electrode 2. Thus, a change in a resonance frequency due to a change in surface reactance is offset by a change in a resonance frequency due a change of the effective size of the electrode, making the resonance frequency almost fixed regardless of a change in temperature. This increases the stability of the resonance frequency to the change of temperatures.  <P>COPYRIGHT: (C)2004,JPO

Title: Method for improving receiving of cdma receiver

IPC: H04B1/707
Filed: 2002-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent complicated mounting in system and to assure estimated value of high quality of the CDMA system which has electric power regulation. SOLUTION: In CDMA transmission, with a purpose of estimating channel pulse responses, on parameter estimated value, correcting factors for equalizing varying electric power levels at multiple receiving blocks are estimated. Noncontinuous oscillation in receiving signals of estimated parameter values can be prevented by estimation and compensation of electric power regulation factors. In UMTS system, for example, electric power regulation information is transmitted with relatively low liability, so statistic assumption assay is used. Then analytic expression is taken based on the note as a complex Gauss process, on transmission channel attenuation in mobile wireless and superposed noises.
