Title: Pulse position modulation communication system
Inventor: YAMADA KUNIHIRO
IPC: H04B1/7073
Filed: 1991-12-02
Abstract: PURPOSE:To minimize the time required for frame synchronization by eliminating the need for a frame synchronization circuit. CONSTITUTION:A serial parallel converter 5 converts a transmission data into a parallel data in a transmitter and an M-value data symbol is sent. Then a pulse of one slot length starting from any of M sets of frames corresponding to a slot from a first slot of the frame till (M-1)th slot is inserted to the frame and consecutive frames are sent to a transmission line corresponding to the data symbol used to send the inserted slot position. A pulse interval signal is inputted to a pulse interval measurement circuit in a receiver and a value (j) is subtracted from the input signal and the value is divided by M and its residue is calculated by a calculation circuit and an output of the calculation circuit is used for a reception parallel data.

Title: Error concealment or correction of sound signal, image signal and video signal
Inventor: MARVASTI FAROKH A
IPC: H04N19/89
Filed: 1999-12-03
Abstract: PROBLEM TO BE SOLVED: To enable error concealment or error correction of, especially a signal transmitted from a radio channel or an ATM channel by forming discrete Fourier transformation of a block consisting of signal samples and forming the inverse discrete Fourier transformation of a Fourier coefficient of the block to form an redundancy increase signal. SOLUTION: A fast Fourier transformation(FFT) processor 1 receives a sampled sound signal x(k) as blocks of N samples and forms a Fourier coefficient X(k). An output signal of the processor 1 reaches an inverse FFT processor 3 from a distortion processor 2 and forms a signal x(i) undergoing filter processing. An output signal of the processor 3 is applied to a sound encoder 4 and a channel encoder 5 which prepares transmission and arranges signals in a transmission frame. A channel decoder receiving a transmission signal returns the frame structure of the signal to the original state and identifies a frame that is disturbed due to transmission or is not received.

Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to improve reliability over a long period of time by using a high-rigidity optical fiber to a moving side optical fiber, thereby providing the optical switch which withstands the bend and wear to be frequently repeated. SOLUTION: The high-rigidity optical fiber is used for the moving side optical fiber 14. The high-rigidity optical fiber is more specifically a titanium coated optical fiber coated with a metal.

Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To correctly measure valance of an anti dsDNA antibody in human humor, by using a DNA tracer obtained by labelling a linear dsDNA resulting from cutting of a cyclic dsDNA with a restriction enzyme. SOLUTION: An antigen DNA tracer is subject to immunoreaction to a standard substance, and a standard curve representing the relation of a bonding rate of the DNA tracer and valance of an anti dsDNA antibody. The DNA tracer is put in an immunoreaction to an antibody in human humor, whereby the bonding rate of the DNA tracer is obtained.
