Title: Handwritten character recognizing device
Inventor: TSURUTA AKIRA
IPC: G06K9/46
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To stably and effectively perform the rough classification of character categories without depending on the number of strokes or the order of writing for a handwritten input character even when the type of a letter is deformed. SOLUTION: A direction quantizing part 7 quantizes the direction between respective coordinate data after normalization while using direction codes in a character recognition dictionary part 16. An image pattern generating part 8 generates an image pattern composed of the segment and off stroke of the direction code corresponding to four image memories and makes the off stroke thinner than the segment through thickening processing. A feature extracting part 9 divides each image memory into 5×5 areas, extracts the number of black pixels from each area as a feature amount and obtains a feature vector. Thus, the feature amount is extracted based on the direction of stroke to be hardly affected by the order of writing or deformed letters, and a handwritten character is recognized without depending on the order of writing or the deformation.  Further, by performing weighing while changing the thickness of the stroke and off stroke, the category of a letter written with one stroke is stably recognized.

Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To reduce the dispersion of braking start timing by preventing the occurrence of erroneous detection due to a time dispersion over a process from the start of the reverse motion of a rotor to the start of braking. SOLUTION: Each of flip-flops 1 to 6 holds the level of other rotation detection signals using the edge of one of rotational angle detection signals as a clock among a plurality of rotational angle detection signals received from the hall elements of a hall motor. Also, NOR gates 16, 18 and 20, and inverters 17 and 19 calculate the conjunction of output values from a plurality of the flip-flops 1 to 6, and the results of the calculation are used as braking start signals. As a result, erroneous detection can be prevented, even when a noise occurs in the rotation detection signals. Also, a time dispersion over a process from the start of the reversal of a rotor to a braking start can be lessened.

Title: Measuring method for magnetic field distribution using nuclear magnetic resonance
Inventor: ISHIKAWA HIKONARI
IPC: G01R33/24
Filed: 1986-10-29
Abstract: PURPOSE:To easily measure a magnetic field distribution in a short time by applying a linear gradient magnetic field and measuring the intensity of a magnetic field at each point where a sample is arranged from a resonance frequency obtained from the sample. CONSTITUTION:Samples are applied with a Z magnetic field with a linear gradient of sufficiently intense H=aZ (H: magnetic field, a: constant, Z: vertical coordinate) by a Z gradient coil 6. An NMR measurement is taken to obtain an NMR signal which is arranged having equal-interval frequency differences because of omega=gammaH (omega: resonance frequency) and H=H0+aZ (H0: magnetic field produced by a magnet) after Fourier transformation in such a uniform magnetic field that magnetic fields that the respective samples sense are completely equal in the absence of a linear gradient magnetic field. Then, a (n)th sample never moves with a Z magnetic field gradient and is positioned at the origin of the linear gradient magnetic field because of the position of the signal in the absence of the linear gradient magnetic field. Consequently, the magnetic field distribution is easily measured in a short time.

Title: Lifetime calculating method for hard disk medium
Inventor: MIYAGAWA YASUNOBU
IPC: G06F3/06
Filed: 1990-09-27
Abstract: PURPOSE:To prevent the destruction of data written in a hard disk medium by recording comulatively the access frequency when the reading or writing operations are applied to the hard disk medium and therefore estimating the lifetime of the hard disk medium. CONSTITUTION:A processor 1 produces a data reading or writing command to a hard disk device 5, and a magnetic head of the device 5 has an access to a recording part 6. This physical access frequency is written in a data area 14 where the cumulative access frequency of the items 12 are recorded for each corresponding cylinder. Then the processor 1 monitors the data value of the cylinder having the highest access frequency based on a program stored in a main storage 2. When the monitored data value exceeds the access frequency defined previously as a lifetime, an exchanging command is produced for the hard disk media. Thus the data written in the hard disk medium are never destroyed.
