Title: Ultraprecise surface polishing method and device
Inventor: IMAHASHI TAKAHIRO
IPC: B24B37/07
Filed: 1993-06-23
Abstract: PURPOSE:To make the relative polishing operation of a work with a polishing member uniform, and to polish evenly by loading the work on a lap on which separate abrasion grains or fixed abrasion grains are provided, and giving a preset looping movement or linear movement to the lap. CONSTITUTION:While a looping or a linear movement is given to a lap 1 on which a work 2 is loaded, a variation is given to the looping or the linear movement. As a result, the polishing surface of the work 2 is polished by the abrasive grains moving at random evenly. While the looping or the linear movement can be controlled automatically by program-moving the X table and the Y table in the square directions each other, the speed is converted by the movements of the tables, and a standardized operation can be prevented. As a result, the abrasive grains do not stay in one place, and an even polishing can be carried out. Furthermore, since all the polishing process can be carried out in one setting, a single worker can deal with plural devices.

Title: Mis memory circuit
Inventor: IKUZAKI KUNIHIKO
IPC: G11C11/34
Filed: 1984-07-25
Abstract: PURPOSE:To prevent the voltage loss of a switching MISFET by connecting a word line to a gate electrode of the switching MISFET as well as to the electrode at one side of a boostrap capacity and driving the word line with a timing signal. CONSTITUTION:A delay circuit 3 produces a timing signal XWC' which is delayed from a word clock XWC by a prescribed time. This timing signal is applied to an end of a bootstrap capacity CB1, for example, which is connected to the output terminal of a word clock generating circuit 1 through the other end. Thus the charging is carried out to the capacity CB1 as well as a parasitic capacity CST produced by the clock XWC which rises with the rising of an address information a0 and -a0. Then the other end of the capacity CB1 is lifted with the rising of the time XWC' and therefore the voltage level of the word clock is increased in response to the lift-up degree of the CB1. Then the gate voltage of a write/read MISFET of a memory cell is higher than the voltage of a digit line. Thus the voltage of the digit line is transmitted to the memory capacity with no voltage loss.

Title: Character recognizing system
Inventor: GOTOU SHIGERU
IPC: G06K9/52
Filed: 1983-08-24
Abstract: PURPOSE:To reduce the effect of the position variation of strokes for a character recognizer by deciding the division coordinates of a square character circumscribed frame on the basis of the centroid coordinates of the black bit number distributions in both X and Y axis directions of a character graphic pattern. CONSTITUTION:The characters on a form are converted into electric signals by a photoelectric converting part 2 and stored to a pattern register 3. At the same time, the line width of an input pattern is calculated by a line width calculating part 4. A subpattern extracting part 5 performs a vertical scan with a pattern register and extracts a vertical subpattern in response to the relation between the continuous length of black bits and the pattern line width. At the same time, the horizontal, right slanting and left slanting subpatterns are extracted by the horizontal, 45 deg. right slanting and 45 deg. left slanting scans respectively. A character frame detecting part 6 detects a character frame and sends the position coordinates of the character frame to a feature extracting part 10. A character projection/production part 7 projects the character pattern to both X and Y axes and produces a black bit number distribution. A centroid detecting part 8 decides the center coordinates, and a character frame dividing point deciding part 9 decides the division coordinates in response to each subpattern. Then the characters are recognized by a recognizing part 12.
