Title: Method for searching orientation of radio wave
Inventor: HIRATA KAZUFUMI
IPC: G01S7/02
Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To realize a high speed searching by extracting only such steering vectors as having elements different from those of others, and subjecting the steering vectors to FFT(fast Fourier transform), multiplication and IFFT(inverse fast Fourier transform) thereby reducing the operational amount. SOLUTION: Steering vectors having elements different from those of others are extracted operational objects and rearranged. A steering vector matrix is then divided into sumatrixes. Subsequently, FFT operation is performed for a sequence cn obtained from the elements of a row vector and a sequence en obtained from the elements of an eigenvector Emin corresponding to the minimum eigenvalue of a correlation matrix. The sequences C(k) and E(k) are then multiplied to obtain a sequence Y(k) which is subjected to IFFT operation. An orientation evaluation function P(θn ) is determined by calculating the reciprocal of the square of an absolute value for each element of a sequence Zn obtained by rearranging all sequences Yn which are obtained by subjecting other submatrixes to similar processing as the extracted submatrix.

IPC: C09D5/24
Filed: 1989-11-13
Abstract: PURPOSE:To lower manufacturing cost, and moreover manufacture electrically conductive paste having the same resistance characteristic as that of the electrically conductive paste which uses metal powder by forming a metal film made of such as Ni, Cu, Ag, or Au, etc., on the surface of glass powder by an electroless plating method, and dispersing the powder in an organic vehicle. CONSTITUTION:After glass beads are well washed in a neutral detergent, they are immersed in a solution, in which hydrofluoric acid is diluted with water to 50 times, for 15 minutes at room temperature and then well washed in water, electroless Ni plating is made, and a Ni film is formed on glass beads surfaces. The obtained glass beads are added with silicone resin, well kneaded using a roll, and seat-likely extended to be hardened at room temperature. Electrically conductive paste having a good resistance characteristic can be obtained since uniform glass powder having inexpensive manufacturing cost is given because thus the electrically conductive paste is manufactured by using powder, in which metal plating is made on only the surface of a glass raw material, without using expensive metal powder.
