Title: Spread spectrum transmitter
Inventor: ETO YOSHIZUMI
IPC: H04B1/707
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To eliminate the influence of co-channel interference due to a multipath while keeping spreading gain constant by converting and demodulating a frequency, restoring a spreading signal to plural of original data, integrating these of data and making them received data. SOLUTION: The high frequency signals received by reception antennas 107 and 127 are converted into intermediate frequency signals by frequency converters 108 and 128 and the signals are demodulated into randam data in demodulators 109 and 129. Spreading code generators 110 and 130 generate the two spreading codes equal to those on a transmission side and these codes are multiplied by demodulation random data by inverse spreaders 111 and 131. At this stage, phases are synchronized in transmission and reception for the repeating period of the spreading code and the outputs of the inverse spreaders 111 and 131 are discriminated as binary codes by discriminators 112 and 132. These two data are integrated by a multiplexor 115 and the received data of the period which is equal to transmission data can be obtained at an output terminal 113.

Title: Optical disk
Inventor: ICHIYAMA YOSHIKAZU
IPC: G11B7/24041
Filed: 1990-08-23
Abstract: PURPOSE:To allow the recording of fixed information by subjecting a DRAW type medium layer to irreversible changes by the light beam output sufficiently larger than at the time of ordinary recording and erasing operations. CONSTITUTION:The DRAW type medium layer 65 is locally heated and melted by a laser beam 22 of sufficient intensity to form bits 66 in exactly the same manner as recording on ordinary DRAW type medium media to execute recording on the DRAW type medium layer 65. Further, the laser beam 22 for reproducing is reflected by the DRAW type medium layer 65 in the same manner as with an ordinary magneto-optical recording medium 52a if the DRAW type medium layer 65 is not recorded at all. The laser beam 22 passes the bits 66 if the recording is made as the bits 66 and, therefore, the reflected light 2 is eventually largely changed in intensity according to the presence or absence of the bits 66. A user is able to record fixed data afterward on the medium which allows repetitive erasing and recording.

Filed: 1995-08-08
Abstract: PROBLEM TO BE SOLVED: To attain proper facsimile reception by controlling whether or not facsimile reception is executed depending on whether or not an on/off time of a reception signal is a specific on/off time. SOLUTION: Upon the receipt of a signal, a cadence detection section 5 stores a count of a cadence-on time counter and a cadence-off time and outputs the counts of the cadence-on time counter and the cadence-off time counter to a system control section 10.
