Title: Radio communication equipment
Inventor: SUZUKI MEI
IPC: H04J13/00
Filed: 2001-02-23
Abstract: PROBLEM TO BE SOLVED: To reduce a circuit scale without affecting an influence to frequency characteristics of a transmission FIR filter of a base band section of a communication system. SOLUTION: A processing order of transmitting power ratio regulating, channel combining, and FIR filtering of the base band section are replaced, a channel output of a 1-bit width before a power value is multiplied is FIR filtered, and then power ratio regulating and channel combining are executed. Adders in the FIR filter are then divided into two. A power coefficient before switching is multiplied by one output, and a power coefficient after switching is multiplied by another output. An enable signal of a signal input to the adder is controlled so as to gradually switch the power coefficients. Thus, even when the power coefficient is changed during transmission, filter output characteristics are maintained constantly.

Title: Liquid crystal display device
Inventor: GOTO MASASHI
IPC: G02F1/1343
Filed: 2001-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device in which a wide viewing angle can be obtained constantly and which is capable of satisfying a desired viewing angle characteristic while maintaining brightness. SOLUTION: In the display panel of this liquid crystal display device, edge sides 22a of a pixel electrode 22 have inclination with respect to the direction of the display surface of the pixel electrode 22. Since the pixel electrode can emit the reflected rays of light of the inclined parts with large angles, the pixel electrode is made to have a constant and wide viewing angle. Moreover, in the pixel electrode, the scattering of the reflected rays of light can be controlled so as to achieve a desired viewing angle characteristic by changing the inclined direction or by changing inclined angles for every side. Thus, it becomes possible to design display whose brightness is not impaired by making a scattering angle large unnecessarily and which is well-balanced with brightness.
