Title: Method and device for safe optical communication link
Inventor: RUTLEDGE CHRISTOPHER L
IPC: H04B10/118
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To reduce the complication of a safe and free space optical distance communication link by modulating light beams with a secret key through the use of a first modulation system and modulating communication information with communication information ciphered by the secret key through the use of a second modulation system. SOLUTION: Communication information which is not ciphered is supplied to a ciphering/timing circuit 100 from a communication information input bus 102 and it is ciphered by the secret key. Relating to a transmitter 200, a laser 202 supplies the light beams to a phase modulator 204 and the light beams are modulated by the secret key from the ciphering/timing circuit 100. Then, they are supplied to an OOK modulator 208. The light beams are modulated with ciphering communication information from the ciphering/timing circuit 100. The transmitter 200 duplexes/modulates the light beams of the laser 202 with the secret key and ciphering communication information and transmits the light beams which are duplexed/modulated to a receiver 300 through a transmission medium 50. Then, communication information which is not ciphered is obtained in a password decoding/timing circuit 400.

Title: Frame synchronizing circuit
Inventor: OWADA SATOSHI
IPC: H04L7/00
Filed: 1987-03-20
Abstract: PURPOSE:To simplify a frame synchronizing circuit by extracting input data with frame synchronization take while using a prescribed low-speed clock from an input data string and inserting it to an elastic store. CONSTITUTION:An input-side synchronizing information circuit 5 receives a detection output FL of a synchronizing detection circuit 4 and generates 4-bit pulse representing synchronizing information SL at each 252 bits of 1.5M data input, and outputted as a low-speed 256-bit data DL inserted to the time slot of 4 idle data in an input-side data extraction/insertion circuit 2a. An output-side synchronizing information extraction circuit 6 extracts 4-pulse signal sH corresponding to the input-side synchronizing information sL from a high-speed 256-bit data DII outputted from the 256-bit elastic store 1. The output-side data extraction/insertion circuit 2b uses a timing signal tH and a 8.192Mb.s clock fH to collect the 256 bit data DH outputted from the 256-bit elastic store 1 in 4 units each, 1024-bit is takes as one frame and the said 1024-bit data is sent extenally while frame synchronization is taken at a period of 125mus in 8 kHz. Since the synchronizing detection circuit of the output side is saved in this way, the circuit is simplified.

Title: Analog and digital converting circuit
Inventor: SHIMIZU OSAMU
IPC: H03M1/14
Filed: 1983-04-14
Abstract: PURPOSE:To perform high-resolution A/D conversion by superposing an input signal upon a triangular-wave signal and performing A/D conversion plural times, and averaging the results. CONSTITUTION:The input voltage E and triangular-wave superposition voltage (e) generated by a superposition signal generating circuit 12 are summed up and converted by an A/D converting part 11 into a digital signal, which is outputted from the conversion part 11 with time and fetched to a digital adder 13. The input signal E+e is converted between 0 and 1 on the longitudinal axis in the 1st A/D conversion, so the A/D-converted value is ''0''. The 4th data from the left in the time-axis direction is between 1 and 2 on the longitudinal axis, so its A/D converted value is ''1''. Thus, values obtained by performing A/D conversion plural times at equal intervals in one period of the triangular wave (e) are averaged. Thus, the resolution is improved by the frequency of A/D conversion (plural times).

Title: Method for coding picture data
Inventor: SUZUKI YOSHIYUKI
IPC: H04N19/136
Filed: 1987-03-19
Abstract: PURPOSE:To attain high-compressing rate encoding of picture date in a state where the gradation reducibility of pictures is excellent, by coding the picture data having gradation into 1st code at every block of a prescribed size and executing vector quantization to the picture blocks coded into the 1st codes. CONSTITUTION:A scanner 41 photoelectrically reads an original containing a picture to be coded with a CCD image sensor and outputs picture data V expressing the picture of the original. A dividing section 42 fetches the picture data V outputted from the scanner 41 and divides the picture data V into blocks of a prescribed size (for example, 4X4) composed of plural picture elements. A pre-processing section 43 finds the mean value, standard deviation, etc., of the picture data contained in each block outputted from the dividing section 42 so as to carry out a pre-process for vector quantization. A vector quantizing section 44 vector-quantizes each block data pre-processed at the section 43. Therefore, the compressing efficiency can be improved and, at the same time, increase in distortion to a reproduced picture can be suppressed.

Title: Extensible sleeve for gravure printing and its manufacture
Inventor: JIYAN HENDORITSUKU FUAN HOOBER
IPC: B41C1/18
Filed: 1983-04-15
Abstract: A flexible thinwalled sleeve for gravure printing is provided, which, going from inside to outside, essentially consists of (1) a slightly conical layer of nickel to provide mechanical strength, (2) a layer of copper, having the structure of high-gloss copper and which is essentially free of internal stresses, said layer having a cylindrical outer surface, (3) a thin, cylindrical layer of hard copper having a structure suitable for electronic engraving and having a gravure pattern on its outer surface, and if desired, (4) a thin protective layer of chrome. These layers are all firmly adhered to each other and especially the two layers of copper cannot be separated by peeling off. Since a high-gloss copper layer, which is free of internal stresses, has been found unsuitable for electronic engraving, and since the layer of hard copper, suitable for electronic engraving, has been found to have internal stresses, which would be unacceptable in the first layer of copper, the two layers must necessarily be different.
