Abstract: PURPOSE:To demodulate a pseudo noise code at high speed with simple constitution by dividing the pseudo noise code into a prescribed time interval and supplying the code to a surface acoustic wave correlation device while giving a delay by the time interval to add the outputs of the correlation device. CONSTITUTION:A carrier wave to phase modulation is branched into four at an input terminal 40 according to the spectral pseudo noise (PN) code, and after they pass through delay elements 41-44 respectively, the result is inputted to surface acoustic wave correlation devices 51-54, and its output signal is synthesized at an output terminal 50. Electrodes corresponding to the time interval of the PN codes T1-T4 divided into four are arranged respectively to the correlation devices 51-54. A delay time Ti (i=1-n) of the delay elements 41-44 is set to satisfy Equation, when T0 is an optional time. Thus, a code start point corresponding to the PN codes 61-64 reaches the correlation devices 51-54 after the PN codes are applied to the terminal 40, they are processed individually at each correlation device and the correlation of the entire PN code having the time interval of T1+T2+T3+T4 is attained.

Title: Rare earth bond magnet
Inventor: MATSUO KURATARO
IPC: H01F1/08
Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To provide a rare earth bond magnet of low cost which does not deteriorate efficiency of a magnetic circuit to be installed when rust preventing countermeasure is taken and can be easily manufactured. SOLUTION: Material powder 2 which is formed by coating oxidation resistant resin 9 on the surface 8 of rare earth based powder 7 is molded in a specified shape (e.g. a rectangular plane board) together with bond 4 and thermally cured, and a rare earth bond magnet 1 is formed. Gaps 6 of the material powder 2 are filled with bond 4. Since a protecting film for preventing rust is not formed like a conventional rare earth bond magnet on the surface 3 or the like of the rare earth bond magnet 1 formed by the above process, a distance to the other magnetic force acting component in a magnetic circuit can be reduced, and deterioration of efficiency of the magnetic circuit can be prevented.  Since rust preventing countermeasure is performed on each material powder, not only generation of rust on the surface of the rare earth bond magnet but also progress of the generated rust to the inside of the rare earth bond magnet can be prevented.
