Title: Integrated dynamic write/read memory
Inventor: UIRIBARUTO MAIYAA
IPC: G06F11/20
Filed: 1984-03-29
Abstract: An integrated dynamic write-read memory includes at least one redundant row and/or column initially excluded from normal operation of the memory but available for normal operation as a replacement. At least one row decoder is connected to the memory matrix and at least one column decoder is connected to the memory matrix for addressing. A column address pulse is fed to the memory matrix for initiating addressing by matrix columns and a row address pulse is fed to the memory matrix for initiating addressing by matrix rows. A normal data path leading out of the memory matrix includes a tristate output connected to the normal data path and actuated by addressing with the stored digital data. Another decoder is connected in the normal data path between the memory matrix and the tristate output with an output connected to the tristate output. The other decoder blocks the normal data path from the memory matrix to the tristate output upon addressing each row or column of the portion of the memory matrix intended for normal operation replaced by a redundant row or column and upon simultaneous external activation of the other decoder. The other decoder also indicates the insertion of a redundant row or column in place of a row or column in the portion of the memory matrix intended for normal operation with the appearance of a uniform indicating signal at the data output.

Title: Magnetic disk device
Inventor: ISHII MITSUO
IPC: G11B21/21
Filed: 1990-03-13
Abstract: PURPOSE:To perform the optimum recording in the whole range of a recording area by providing a position control means for deflecting a floating commencing position of a floating type magnetic head at random in the reading area on a disk recording medium. CONSTITUTION:The disk device is provided with the position control means 11 for changing the floating commencing position of the floating type magnetic head 8 at random in the recording area on the disk recording medium 1. Consequently, no local abrasion of the disk recording medium 1 due to friction with a floating slider 4 takes place, and hence the recording area is hardly damaged even without providing a sliding area on the disk recording medium 1. Then, since the abrasion on the disk recording medium 1 takes place uniformly, floating characteristics of the floating type magnetic head 8 are not dependent upon its place. By this method, a recording capacity can be secured, and the optimum recording can be performed in the whole recording area.

IPC: G01R19/165
Filed: 1979-05-21
Abstract: PURPOSE: To achieve the improvement in the accuracy of ripple adjustment without any observing device by reading the analog input signal directly into a memory unit, judging the same by the program of a CPU unit and displaying the results of the judgment.  
     CONSTITUTION: The difference E of the maximum value MAX and minimum value MIN of analog input waveform is taken and whether it is within a permissible value EO or not is jueged by the program of a CPU unit 6 and is announced to the operator. When the ripple value E is still higher than the permissible value EO, a lamp 10 is put ON and when the ripple value becomes lower than the permissible value EO, the lamp 10 is put OFF. The operator adjusts a volume control 2 for adjustment while viewing the lamp 10. If at this time the adjustment is made in the direction of decreasing the ripple valve E, the lamp 11 goes OFF and if converse, the lamp 11 goes ON. In this way, the ripple value may be adjusted to a minimum without requiring any observing device such as synchroscope.
