Inventor: SENOO MAKOTO
IPC: G06K9/36
Filed: 1983-06-09
Abstract: PURPOSE:To ensure the accurate extraction even to the changes of vertical and horizontal sizes of a picked-up picture by calculating the enlargement ratio from the distribution of gradation histograms of the picked-up picture and estimating the position of another pattern from a character pattern serving as a base point to extract a character pattern. CONSTITUTION:The gradation histogram of an enlarged picked-up picture stored in a picture memory is fisrst obtained, and this result is supplied to a row register and a column register 6. The contents of the register 6 are equal to the horizontal size and the horizontal space of the maximum picked-up picture due to a certain bit. Then the distribution of gradation histograms of the character pattern of the 1st column, i.e., the character pattern of the base point is obtained from the contents of the register 6. Then the enlargement ratio is calculated from said distribution width and the know value of a reference picked-up picture. Based on this ratio, the positions of character patterns of the 2nd and 3rd columns are estimated. Then the extracting position of the character pattern is obtained from the distribution of the gradation histogram of the character pattern at the estimated position.

IPC: B41J2/02
Filed: 1978-08-26
Abstract: PURPOSE:To obtain an small-sized effective ink jet recording head having a good characteristic with a reduced drive voltage by fixing a vibration unit formed with a plan vibration element and a vibration plate are adhered to each other, by an annular vibration plate pressing member to a head body. CONSTITUTION:A vibration unit is fixed by a pressing member VPP to a main body to be set practically perpendicular to and coaxial with a main shaft direction of a nozzle NZ.

Filed: 1987-04-27
Abstract: PURPOSE:To achieve a higher time accuracy, by selectively using more accurate one as time counting element among output frequencies of a commercial AC power source and reference clocks from an oscillation circuit. CONSTITUTION:A microcomputer 18, first, reads in a pulse voltage V1 from a waveform shaping circuit 20 to which an output of a power source circuit 19 is provided as clock CK1. Here, a pulse width of the clock CK1 is set at P1. Subsequently, the computer 18 reads in a frequency division signal S22 of a frequency dividing circuit 22 which divides the frequency of a reference signal S21 from an oscillation circuit 21 as clock CK2. A pulse width of the clock CK2 is set at P2. Then, an absolute value P0 of a difference between the pulse widths P1 and P2 is compared with a reference value P and when P0<P, a clock is driven based on an output frequency of a voltage V1. On the other hand, when P0>=P, the clock is driven based on the signal S21. This makes highly accurate ones of the clocks and frequencies effective selectively.

Title: Manufacture of semiconductor thin film
Inventor: HASHIZUME TSUTOMU
IPC: G02F1/1368
Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To prevent a semiconductor thin film formed on a substrate from being damaged by a condensed high-output energy beam by irradiating the thin film with the beam while the thin film is scanned with the beam by deforming the beam into a plate-like shape. SOLUTION: In a method for scanning a thin film with a laser beam, the laser beam is projected upon the thin film by moving a mirror 24 at a speed of 1 mm/sec in the Y-axis direction and the width of the laser beam in the X-axis direction is adjusted by changing the distance between a concave lens 22 and a convex lens 23. In order to prevent the reduction of the annealing effect of the laser beam, the energy density of the beam is increased by means of a convex lens 25. Since no overlapping part is formed in irradiated areas produced by the repetitive scanning with the laser beam and the area where the speed approaches zero, namely, the inverting area of the beam in the scanning direction is formed in the annealed area, the beam does not stop and no overlapping irradiated part is formed.  Therefore, the materiality variations of the semiconductor thin film in the annealing area is eliminated and, accordingly, the damage of the thin film by the laser beam can be prevented.
