Title: Character segmenting device
Inventor: NAKANO TOMOAKI
IPC: G06K9/34
Filed: 1988-08-23
Abstract: PURPOSE:To obtain respective characters, which are included in concentration picture data, as a binary picture by repeatedly execute re-binarization so as to unify character lines, which go to be a different label, regarding the label not to be unified to the character line as a noise and removing such a label. CONSTITUTION:The concentration picture data are divided into several small areas and an optimum binarizing threshold for character area detection is computed in each small area by using a binarizing means 1200 by divided areas. Then, the concentration picture data are binarized. Next, by using a re- binarizing means 1800 by character areas, the propriety of the character picture data in each character area to be outputted from a binarizing means 1700 by character areas is decided and the concentration picture data are re-binarized so as to satisfy a condition for the binary picture data of satisfactory quality. Then, the satisfactory binary picture data of the respective characters are outputted. Thus, the respective character areas can be exactly detected from the concentration picture data, which are outputted from an image-pick up means 1000, and further, the detected character picture data go to be the satisfactory binary picture data of suitable character line width not to accompany the noise.

Title: Magnetic recording medium
Inventor: NAKAGAWA ATSUSHI
IPC: G11B5/708
Filed: 1988-08-23
Abstract: PURPOSE:To obtain the magnetic recording medium having excellent traveling durability under environmental conditions of a wide range by holding specific benzene tricarboxylic acid into a magnetic layer. CONSTITUTION:The magnetic layer holds the triester of benzene tricarboxylate expressed by formula I therein or thereon. In formula, R1 to R3 denote a straight chain or branched alkyl group or alkenyl group; the total of the carbon atoms of R1, the carbon atoms of R2 and the carbon atoms of R3 is >=22. The benzene tricarboxylic acid has itself a lubricating effect and is capable of imparting the traveling durability to the magnetic recording medium; moreover, this acid has the proper affinity to a binder resin and, therefore, white powder is hardly generated even at a low temp. and the size of the molecules is relatively large. The evaporation thereof from the magnetic layer hardly arises even at a high temp. The traveling durability of the magnetic recording medium in the wider temp. range is improved in this way.

Title: Background update processing method for passer-by number detector
Inventor: TOKUYAMA TAKASHI
IPC: G06M7/00
Filed: 1991-08-21
Abstract: PURPOSE:To enable background update without being affected by gradation fluctuation caused by illumination noise by defining the gradation of a background image as a reference and preventing a differential processing from being executed concerning the gradation of a sample image higher than the reference. CONSTITUTION:In the case of calculating the moving direction of passers-by and the number of the passers-by while using image data fetched by an image input part 2 of a passer-by detector, the fixed differential processing is executed to execute binarizing and compression processings by calculating difference from the sample image to be next fetched while defining the first image data as the background. Afterwards, the number of fixedly differentiated compressed picture elements is counted and according to the positions of the picture elements, signs (+) and (-) are attached. Then, the number of picture elements changed from the (+) direction to the (-) direction and the number of picture elements changed from the (-) direction to the (+) direction are summed up and divided with the number of reference images for one passer-by. When any object is set on the floor as the background, the differential image of this object is obtained by the fixed differential processing and since this differential image is not moved, however, the background is updated by judging N1 changes of the picture element number.

Title: Rotary head type recording and reproducing device
Inventor: OGURA MASAYOSHI
IPC: G11B27/036
Filed: 1991-08-21
Abstract: PURPOSE:To always rerecord a correct signal in a correct area by controlling relation between a positioning signal and a switching signal to be fixed at the time of rerecording of a part of a recording track. CONSTITUTION:Error DELTAt between a time difference (t) between a switching signal SWP and a first sampling pulse ATFS1 and a format is detected to discriminate whether the error DELTAt is positive or negative. When it is positive, the extent of delay of the switching signal SWP is increased because the position of the sampling pulse ATFS1 is later than the format and the delay quantity is small. When it is negative, the delay quantity of the switching signal SWP is reduced since the position of the sampling pulse ATFS1 is eariler than the format and the extent of delay is large. Consequently, the switching signal SWP in fixed relation to the first sampling pulse ATFS1 is obtained.

Title: Resin composition and molded material
Inventor: SUDO KUNIYOSHI
IPC: B32B27/20
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To obtain a resin composition which neither causes any damage to an incinerator because of reduced calorific value in incineration nor generates a large quantity of ashes even after incineration by blending a synthetic resin with rice hulls having a specified particle diameter. SOLUTION: This composition consists of 100 pts.wt. synthetic resin and 10-500 pts.wt. rice hull powder having a mean particle diameter of 50-200μm. If the amount of the rice hull powder added is less than 10 pts.wt., the reduction in the calorific value of used moldings in incineration will be insufficient; if it is above 500 pts.wt., the strength, etc., of the moldings will be insufficient, and it will also be difficult to mold the composition. The ratio of the synthetic resin to the rice hull powder used may vary depending on the purposes.  For example, it is desirable to mix 100 pts.wt. synthetic resin with 10-100 pts.wt. rice hull powder in the case of moldings, such as a film and a thin sheet, of which flexibility is required, while it is desirable to mix 100 pts.wt. synthetic resin with 100-500 pts.wt. rice hull powder in applications to plate and rod stocks used as building materials, etc., or a railroad tie, etc., where high rigidity is required.
