Title: Polarizer
Inventor: TAMAGAWA SUSUMU
IPC: H01P1/162
Filed: 1982-12-23
Abstract: PURPOSE:To improve the factor of elliptical polarization of an antenna by providing a load absorbing only the polarized wave component due to a reflected wave sent from a sub-reflecting mirror to a polarizer used for a primary radiator of a Cassegrain antenna. CONSTITUTION:The 4GHz band of a reflected wave generated by the Cassegrain antenna sub-reflecting mirror is a left-handed circularly polarized wave and the 6 GHz band is a right-handed circularly polarized wave, and when the reflected wave is returned to the polarizer through a circularly polarized wave generator, the wave in the 4GHz band becomes a vertically polarized wave and the wave in the 6GHz band becomes a horizontally polarized wave. The vertically polarized wave in the 4GHz band enters the left side of a circular waveguide 20, because no magnetic field component exists in the lower guide wall the wave is not coupled to a slit of a branching waveguide 23 but coupled to a coupling loop 29 and passes through a coaxial low filter 30 and is absorbed in a resistive terminator 31. On the other hand, the horizontally polarized wave in the 6GHz band is not coupled by the branching waveguide 23 and the absorbing load 24 because of filters 27, 30 but absorbed in a resistance plate 33 in the 2nd circular waveguide 22.

IPC: G06M3/00
Filed: 1985-10-18
Abstract: PURPOSE:To shorten the retrieval time by detecting in parallel many event flags, also dividing a whole body into blocks, and skipping the block in which no event flag is set. CONSTITUTION:When detecting an event, the address register 202 of a macro- flag part is brought to an increment successively by one each from '1' to L2, and the data of L1 bit width of the macro-flag part 201 is transmitted to the first ROM address register part 204, and goes to read the first ROM part 203. As for the contents of the ROM, only the nearest bit to MSB of its address is '1' and other bit is '0'. The output of the first ROM part 203 takes exclusive OR with the output of the macro-flag part, and its result is inputted to the first ROM address register. When the address register of the first ROM part 203 is '0', the macro-flag part address register 202 is brought to an increment, and goes to read the data L1 bit of the next address. The output of the first ROM part 203 is encoded by the first encoder part 206 and becomes a log2L1 bit.
