Title: Manufacture of semiconductor element
Inventor: ONO TOSHIHIKO
IPC: H01L21/302
Filed: 1979-04-18
Abstract: PURPOSE:To provide an accurately fine pattern on a semiconductor element by sputter etching a polysilicon by inert gas or O2 with a metal layer as a mask when patterning two layer wirings of the polysilicon and the metal layer. CONSTITUTION:An opening is perforated at a SiO2 film 4 for coating the element regions 2, 3 of a silicon substrate 1, and a PSG5, a polysilicon 6 and aluminum layer 7 are sequentially superimposed thereon. A resist mask 8 of predetermined pattern is formed thereon, the aluminum 7 is etched with phosphoric acid, and the polysilicon 6 is then sputter etched by Ar or O2 or the like. Since the sputter etching can be controlled in etching rate readily and have low etching rate, it can suitably stop the etching process of the layer 6 without almost etching the lower PSG5, does not etch the side surface without eliminating the protecting effect of the PSG so as to form faithfully a pattern to the mask.

Abstract: PROBLEM TO BE SOLVED: To highly precisely, effectively and automatically enable matched image drawing corresponding to pattern distortion of each aligner, by drawing an image by updating the quantity for correcting the position of, e.g. electron beam image drawing in the next stage, according to the quantity of optical distortion of an aligner in the preceding stage which changes with exposure. SOLUTION: In a pattern mask 6a (reference mask), marks 8a for distortion measurement are arranged in a lattice type at constant pitches. The mask 6a is used as a top wafer of each lot. The pattern mask 6a is projected by an optical aligner and transferred on a wafer. The position of each of the marks 8a which are formed on the wafer is measured by an electron beam image drawing equipment, and the distortion form common to the wafers in this lot is automatically obtained. On the basis of the distortion form, image drawing positions by an electron beam to wafers are corrected, in each lot. That is, the distortion form common to each wafer is previously measured, and image drawing positions are corrected, on the basis of the measured results and position data obtained by detecting the marks.

Title: Optical character reader
Inventor: AKIMOTO TAKASHI
IPC: G06V30/262
Filed: 1981-03-31
Abstract: PURPOSE:To reduce the error reading percentage of the entitled reader by checking whether an answer derived by the analogous method is appropriate or not on the basis of the compensation of projected values between characters before and behind an objective character. CONSTITUTION:A character pattern row photoelectrically converted by a photoelelctric  conversion part 1 is quantized by a quantizing circuit 2. The quantized character pattern row is cut out into character patterns consisting of 1 character each by a cutting circuit 3. The circuit calculates the projection value of each cut character pattern to  store projection values corresponding to the character patterns of 1 line in a projection  value memory 8. Simultaneously, each cut pattern is normalized by a normalization circuit 4 and preprocessed by a preprocessing circuit 5, and an anglogous degree calculation circuit 7 calculates the analogous degree to each standard character pattern stored  in a recognition dictionary 6 and sends the standard character with the highest analogous value to a discrimination circuit 10. The circuit 10 discriminates whether the 1st  proposed character with the highest priority is an appropriate answer or not from the  difference of projected values between the said proposed character and the highest proposed character of the succeeding character on the basis of the correlation of compensation values between the proposed character and the character stored in a conpensation table 9.

Filed: 1995-03-08
Abstract: PURPOSE: To specify the classification of an area consisting of a character pattern group at a high speed. CONSTITUTION: An image inputted from an image input part 201 is separated for every area by a data separation part 202. A control part 203 uses a character recognizing part 204 to recognize a separated character image in each area after delivering it thereto.

When it exists, the classification of a noticed area is specified at that time, therefore, the fact is reported to the control part 203. The control part 203 receives the result, and stores data in the noticed area in an item/data storage part 208.

Title: Bow thruster gate device for marine vessel
Inventor: SUZUKI KAZUHIRO
IPC: B63H25/42
Filed: 1989-02-28
Abstract: PURPOSE:To improve reliability on function and operation with a simple structure by constituting a thruster gate to be rotated so as to make it not only going up and down by drive of an actuator but also to be turned in and around the closing position. CONSTITUTION:When a hydraulic cylinder 12 is operated out of the closing position and an upper guide pin 9 is pulled up, an upper part of the thruster gate 1 is rotated to the rear with a guide pin 4 at the central part as the fulcrum via a link 8 and then the whole thruster gate 1 is guided by a guide rail 5, going upward, and thereby a thruster tunnel 2 is opened. When the hydraulic cylinder 12 is operated in the reverse direction, the thruster gate 1 goes down and, after receiving the guide pin 4 at the central part by a bearer 6, the upper guide pin 9 further going down is supported at the closing position by rotating an upper part of the thruster gate 1 forward via the link 8. Thus, the thruster gate 1 is made possible to be opened or closed without entailing any interference with a hull shell plate 3 and, what is more, any step difference is not produced in a closed state, thus supporting force against external pressure can be obtained.

IPC: B41J2/045
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recorder in which ink can be ejected stably from a nozzle opening regardless of fluctuation in the number of pressure generating elements to be driven. SOLUTION: In an ink jet recorder, the number of pressure generating elements to be driven is counted by a counter circuit 87 during next recording cycle. A waveform generating circuit 85 reads out parameters corresponding to the count from a memory 81 and generates a drive signal COM having such a waveform as correcting distortion of waveform caused by parasitic inductance if the number of pressure generating elements to be driven is high. Consequently, a drive signal COM having an optimal waveform can be applied constantly to the pressure generating element regardless of fluctuation in the number of pressure generating elements to be driven.

Filed: 1990-02-28
Abstract: PURPOSE: To improve noise control by deciding the motion vector of a detected object by minimizing a mean-square Gray value difference over the intersection set of deviated mask segments and utilizing the difference between the centroid vectors of corresponding segments as a starting vector at the time of minimizing. CONSTITUTION: One column of binary object masks are calculated by the binarization of a difference image column from an input image stream and a background image column through the use of one threshold value, those threshold values are used for controlling spatial selectivity at the time of calculating the background image column and those segments are decided with their dimension and centered position. Then the motion vector of the detected object is decided by minimizing the means-square Gray value difference over the intersection set of the deviated mask segments and the difference between the centroid vectors of the corresponding segment is utilized as the starting vector at the time. Thereby necessary noise suppression in the object mask is executed by the application of a median filter.
