Title: Method and apparatus for predicting and coding video information
Inventor: MIN HON CHIYAN
IPC: H04N7/26
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To reduce deterioration of a screen due to quasi-optimal selection of a predictive mode in a video signal compression system by an MPEG. SOLUTION: A video input signal is converted into a pixel into a pixel block 57. Then, plural predictive blocks are formed as the ones to represent an input block 60. Each predictive block is generated by different predictive functions and provided with a related correlation factor CF to prevent the degree of correlation between an input block and the predictive block. The factor is obtained by subtracting the criterion of a correlation component which varies with a low frequency from a correlation index 35. The correlation factors are compared with each other 45, and a compression block related with the predictive block with the lowest CF value is selected as an output block. This processing is repeated for other input blocks, and a compression video output signal is formed by combining the selected compression output blocks.  The selection of the predictive mode and motion estimation of an image are improved in existence of image fading, without requiring a fading detection circuit by a conclusive factor CF.

Title: Method and device for data read and write of magnetic card
Inventor: KAMIO HIROSHI
IPC: G11B5/02
Filed: 1978-09-18
Abstract: PURPOSE: To make it possible to discriminate easily a forged card by recording random data on a magnetic card by an extremely-slight magnetic field by superposing upon desired data.  
     CONSTITUTION: With contact C of relay RL made, a current flowing through magnetic head 1 is increased to provide a sufficient magnetic field, thereby recoding desired data from FM modulator circuit 3 on a magnetic card. With contact C broken next, the current is decreased to generate a slight magnetic field, thereby recording random data on the magnetic card superposing upon the previously- recorded data. To read this record, the random data are demagnetized by a current equal to that in recording and then the desired data read. Those write, erasing read operations are controlled by using terminals 8, 9 and 13. Using this magnetic card makes it possible to discriminate a forged card because it has no random data.

Title: Active carbon additive for rice cooker
Inventor: NISHIKAWA MASASHI
IPC: B01J20/20
Filed: 1994-04-28
Abstract: PURPOSE:To obtain an active carbon additive for rice cookers which is formed by capsulating active carbon particles into a bag consisting of a transmissive sheet and is used to improve the taste of cooked rice right after cooking or to remove the smells, etc., generated at the time of cooking or when the cooked rice is preserved for a long period of time after cooking. CONSTITUTION:This active carbon additive for rice cookers is formed by capsulating the active carbon particles 5 into the bag 4 consisting of the transmissive sheet. While the sizes of the active carbon particles are not particularly limited, the particles of the grain sizes small to some extent, for example, about 10 to 30 meshes are more preferable. Any transmissive sheets are widely usable, insofar as these sheets are made of the materials allowing permeation of water and steam. Non-woven fabrics, woven fabrics, paper, etc., are usable as the transmissive sheet. However, particles are generated in the active carbon by friction between the particles with each other during use in some cases and the sheet is required to prohibit the transmission of the extremely small particles and is further required not to contain the components which elute when boilied. The sheet including the non-woven fabric consisting of ultra-fine fibers, for example, melt blow fibers, of a fiber diameter of about <=0.1 denier is more preferable as the transmissive sheet.

Title: Magneto-optical disk
Inventor: FUKUSHIMA ISAMU
IPC: G11B11/105
Filed: 1989-05-08
Abstract: PURPOSE:To prevent warpage by forming a protective layer having a specific internal stress on a recording layer or on a substrate on the side opposite to the recording layer. CONSTITUTION:The protective layer consisting of a cured resin having <=1X10<11> dynes/cm<2> internal stress of the cured film after curing is formed on the recording layer and/or on the substrate on the side opposite to the recording layer. The stress and strain generated in the substrate by shrinkage on curing of the protective layer are greatly decreased and the magneto-optical disk which is free from the warpage is obtd. even if the disk is of a veneer specification. The stress and strain between the substrate and the respective layers of the recording layer and the protective layer are drastically decreased as well and, therefore, layer defects, such as cracks and pinholes, are hardly generated. Since the stress and strain between the layers are small, the weatherability, durability and reliability of the magneto-optical disk are enhanced without allowing the substrate, recording layer and the protective layer to be deformed over a long period of time.
