Title: Method for inserting robust digital electronic watermark signal to data and method for detecting electronic watermarks
Inventor: COX INGEMAR
IPC: H04N7/24
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To obtain a procedure for insertion of electronic watermark to data that is applicable to image, audio and video and multimedia data. SOLUTION: Data, to which an electronic watermark is inserted, is divided into a series of blocks each consisting of n×n pixels such as 8×8 pixels in compliance with MPEG, and the blocks are combined to form one total block to which the electronic watermark is inserted. The same electronic watermark signal is distributed to a series of the entire blocks by various methods and an insertion algorithm can be changed without affecting a decoder. In the decoding, first DCT coefficients of each block consisting of 8×8 pixels are totalized (12), then the electronic watermark is extracted from the totalized block (18). Since the sum of DCT blocks is equal to DCT of the sum of pixel blocks, the data are efficiently decoded from both the space domain and the frequency domain. Geometrical distortion is processed by the space domain depending on the symmetry in the decoding process, and other signal distortion can be processed in the frequency domain region.

Title: Gas laser apparatus
Inventor: KOBAYASHI SHIGEAKI
IPC: H01S3/032
Filed: 1985-08-05
Abstract: PURPOSE:To obtain a stable laser output, by setting the magnetic field intensity of a magnetic field generator, which is provided at the outer surface of the thin discharge tube part of a laser tube,at a value higher than the saturating point of the laser output. CONSTITUTION:When a magnetic field is imparted to a thin discharge tube part 3 from a permanent magnet 8, cycrotron movement owing to an electronic field and the magnetic field are generated in the thin discharge tube part 3. Electrons in a gas laser medium collide with neutral gas particles and are drifted to the wall of the tube. Thus the movement of the electrons in the axial direction of the tube is decreased. Therefore, the electron temperature in the electric field in the axial direction of the tube, i.e., within the tube, is increased. The loss in energy within the tube is increased, however, the laser output is increased more than that. The laser output is rapidly increased when the magnetic flux density exceeds 400 Gauss. The output is saturated at about 800 Gauss. Therefore the magnetic field intensity of the permanent magnet 8, which is attached to the outer surface of the thin discharge tube 3, is set at a value higher than 800 Gauss, e.g., at 860 Gauss or more. Then the laser output is not fluctuated even if the magnetic intensity is changed with the temperature of the permanent magnet 8. Thus the output is stabilized.

Title: Reproducing device
Inventor: KASHIDA MOTOICHI
IPC: G11B15/087
Filed: 1985-08-06
Abstract: PURPOSE:To attain quick reproduction of additional information by providing the mode reproducing main information and the additional information from one of plural areas and the mode reproducing only the additional information from all the plural areas. CONSTITUTION:The tape speed reproducing an ID signal of all the areas should specify the following two conditions; the tape speed should reproduce the ID signals ID 0-ID 5 at the same time because of the different recording location of the signals even in an area and the ID signals of all the areas are detected at the minimum time depending on the tape speed. When the signals ID 0-ID 5 are detected by one head trace at an area, the head trace location is shifted little by little by 2 track pitches forward and backward, then the ID signals on all the areas are reproduced by one head trace with respect to each area. Thus, in setting the tape running speed to (40n+1+ or -l/m)V, the ID signals of all the areas are detected by 2m times of head traces.
