IPC: G01S3/782
Filed: 1991-04-17
Abstract: PURPOSE:To enable a range of a typical value of a characteristic amount of each target type to be assumed to be set with a boundary in an ambiguous form and further a target type to be classified by evaluating ambiguity of this prior information based on an actual target value of the amount of characteristic.

Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic tape device for effectively using even a magnetic tape in which end-of-data(EOD) can not be properly written because of power failure or the like. SOLUTION: When recording a track b116 in a magnetic tape 102, a version number 119 showing the freshness of time recording that track b116 in the magnetic tape 102 is written.

Filed: 1989-04-04
Abstract: PURPOSE:To shorten the access speed by recording vortically a signal in the reverse rotational direction on a first face and a second face, and executing reproducing without varying the rotation at the time of continuously reproducing and accessing extending over both the faces. CONSTITUTION:On the A face of an optical disk 21, a signal is recorded vortically from the inside periphery to the outside periphery, and on the B face, it is recorded vortically in a reverse turn from the outside periphery to the inside periphery. First of all, an optical pickup moving device 24 moves an optical pickup 23 to the innermost periphery of the A face of the disk 21, and simultaneously, rotates the disk 21 in the prescribed direction. As a result, the pickup 23 reads the signal from the A face and starts the reproduction. In such a case, on the A face, since a track moves to the outside periphery, the moving device 24 moves the pickup 23 to the outside periphery of the disk 21. When it reaches the outermost periphery of the A face, the pickup 23 moves to the inside periphery of the B face, and starts the reproduction of the B face. In such a way, since both the faces can be reproduced continuously without varying the rotation of the disk 21, the access speed can be shortened.

Title: Gradational character generating method
Inventor: SHIBATA HIROYUKI
IPC: G09G5/00
Filed: 1991-01-23
Abstract: PURPOSE:To generate gradational characters which varies in density from linear threshold value patterns and density information on the characters. CONSTITUTION:Character pattern data is constituted of position information on a skeleton point Pi, line width information at the skeleton point Pi, and density information at the skeleton point Pi. Further, a linear threshold value matrix for generating a basic pattern is generated and stored. The linear basic pattern is generated first from the density information on the skeleton point and the threshold value matrix. At this time, when the size of the threshold value matrix and the line width are different, an enlarging or reducing process is performed. Thus, basic patterns which are generated by skeleton points are put together to generate a pseudo gradation pattern. This is sectioned into areas of optional size and gradational character data is generated according to the number of black dots in each area.
