IPC: H04N19/136
Filed: 1986-10-28
Abstract: PURPOSE:To eliminate the influence of a peripheral edge to a statistic, by finding the statistic of each component by using part or all of the transformational coefficient matrices of blocks which are not in the peripheral area of a picture in transformational coefficient matrices. CONSTITUTION:Orthogonal transformation is performed on all blocks in a picture matrix A and calculation of statistics of transformational coefficients is carried out to the blocks in another picture matrix B only. Namely, the transformational coefficient matrix alpha(i, j) (where i, j=0, 1, 2,..., m-1) of each block is found by dividing the picture matrix A of M X N picture elements into blocks of m X m picture elements and performing discrete two-dimensional orthogonal transformation to each block. In this case, however, the statistic of each component is calculated on the transformational coefficient matrices alpha(i, j) of blocks which belong to the picture matrix B and, at the same time, to which statistic calculation is performed, only. By owitting the blocks in the peripheral area of film from the calculation of the statistic of each components of transformational coefficient matrices in such way, bad influences of a peripheral edge to a statistic can be eliminated.

IPC: H01Q7/04
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To solve problems of a communication area and radio wave laws by combining n loop antennas which have an open area that is 1/n of the open area of a desired loop antenna and also configuring it with one conductor. SOLUTION: A loop antenna 62 is configured by winding an antenna of a radio card system in turn so that four loop antenna elements 61 which are 1/4 of a desired antenna size can be formed. Electric fields due to current that flows into sides inside the elements 61 are mutually negated, and a radiation electric field pattern of a remote field is the same with the radiation pattern of an antenna in which current flows through only an outermost circumference. An effect of geometrical distance with divided antennas appears at a close distance and radiation field intensity at angles except the normal line direction of a radio card is increased. With this, a practical communication area is drastically expanded without increasing the radiation field intensity of radio wave laws. A small loop antenna can be arranged inside a desired loop antenna.

Title: Optical transmitter-receiver and optical transmission/ reception system
Inventor: TOUMON MOTOJI
IPC: H04B10/27
Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To make an optical transmitter-receiver low in loss, small in size and low in cost by reducing the intensity loss of an optical signal in the branching part of a path for transmission and a path for reception for the optical signal. SOLUTION: When transmitting an optical signal for transmission emitted from a laser light source 11 to an optical fiber 16, an impressing voltage variable power source 14 impresses a voltage having a refractive index n1 for a liquid crystal panel 13 to transmit the optical signal for transmission to the liquid crystal panel 13. Thus, the optical signal for transmission is transmitted through the liquid crystal panel 13 and converged to the optical fiber 16 ith the extremely reduced loss. When receiving an optical signal for reception emitted from the optical fiber 16, the impressing voltage variable power source 14 impresses a voltage having a refraction factor n2 for the liquid crystal panel 13 to fully reflect the optical signal for reception toward a light receiving element 19 to the liquid crystal panel 13.  Thus, the optical signal for reception arrives at the light receiving element 19 with the extremely reduced loss.
