IPC: G09G5/18
Filed: 1978-05-10
Abstract: PURPOSE: To obtain a desired interlace ratio by selecting the period of vertical scanning for every field and changing the period of vertical scanning of required fields.  
     CONSTITUTION: In case that 3:1 interlace scanning is obtained, individual vertical scanning driving signals are given to the first field L1, the second field L2 and the third field L3. For example, the first field period T4, the second field period T5 and the third field period T6 are made 10/3 times, 10/3 times and 7/3 times as long as horizontal scanning period H respectively, so that 3:1 interlace scanning can be obtained. Vertical scanning driving signals are obtained by shifting scanning pulses 6' successively by 1/3H and 2/3H in the first field and the second field respectively. That is, desired scanning pulses corresponding to scanning times of respective fields are generated from one pulse and are used for every field.

Title: Manufacturing of integrated element
Inventor: GOKAN HIROSHI
IPC: H01L21/3065
Filed: 1979-05-04
Abstract: PURPOSE:To improve yield rate in IC element flattening process, by providing a resist mask, etching it by radiating ion beam obliquely, covering it with a thin film and removing the mask. CONSTITUTION:If etching is done on a rotary specimen table by radiating ion beam at an angle inclined by a prescribed angle theta from the vertical direction, a gradual slope 6 is caused by shadow effect and a steeply inclined section 7 is caused by the oblique radiation of beam. If the angle theta is small, bottom section of the section 6 becomes short causing to the section 7 a layer 5 of re-adhesion of atoms. At this time, end sections of a mask 3 on a pattern 2 are scraped off obliquely causing it to become trapezoid shape. If the angle theta is large, etching prevents formation of the layer of re-adhesion of atoms, and the mask becomes almost vertical or reverse trapezoid shape. And therefore, by selecting an appropriate figure for the angle theta to prevent formation of the atom-readhesion layer on the steeply inclined section 7 and etching a substrate 1 with extended etching, it is possible to eliminate the gradual slope 6 and to obtain a pattern 2 of rectangular section. Further, if a resist 3 is exfoliated by soldering a thin film 4, as it becomes easy to be exfoliated, yield rate in flattening process can be improved.

Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a speech segmentation device which can properly segment even a document that has a small estimation error of segmentation and has a voiceless section. SOLUTION: A speech waveform and a character string are inputted to a preprocessing part 102 through an input part 101 and segmented into syllables.
