Title: Deep-groove etching
Inventor: GOTOU TOMOAKI
IPC: H01L21/302
Filed: 1989-01-30
Abstract: PURPOSE:To enable deep-groove etching with less side etching amount and high etching speed by depositing an aluminum film and a photoresist film on a single crystal silicon substrate, and carrying out etching using mixed gas of sulfur-hexafluoride and oxygen. CONSTITUTION:An aluminum film 3 is deposited on one surface of a silicon substrate 1, and a resist film 4 for photoprocessing is deposited further thereon. Then, after the resist film 4, at the part where a recess in the silicon substrate 1 is to be formed, is removed, exposed aluminum film 3 is removed by etching. A pattern, in which a recess forming part 5 is exposed, is formed with the resist film 4 on the left aluminum mask being left as it is without being peeled off. Then, etching is carried out by reactive gas consisting of SF6 and O2 in a reaction chamber 11 using an anode coupling type plane parallel plate dry etching device. Thus, the recess can be formed with very small side etching amount in the silicon substrate, and with a speed not less than 25 times larger as compared to that in the conventional cathode coupling type one.

Abstract: PROBLEM TO BE SOLVED: To change the attribute of a character in accordance with the picture of a background by comparing an average color with the color of a character string and changing the color of the character string when color difference between them is small and the character string is superimposed on its area. SOLUTION: A page description document which is described in a read template is analyzed, the color of the character defined as default is inspected, the template is analyzed and the coordinate of the character string arranged in the page is obtained. A picture file name 335 and a mask file name 340 are inspected, the respective files are read and a mask area 350 in a coordinate system on the page is obtained. It is judged whether the coordinate of the character string enters in the mask area 350 of the mask file or not. When the character string enters into the mask area, it is expected that the character string is superimposed on the mask area so that the color of the character string is compared with that of a picture area corresponding to the mask area.  When the color of the character string and that of the picture area are the similar ones, the color of the character string is changed based on the table 370.

Abstract: PURPOSE:To automatically and surely perform the changing of the vibration amplitudes of the  mold remotely even during casting by turning a ring gear by a driving source such as hydraulic  cylinder to change the phase of the rotating direction of an eccentric sleeve and eccentric shaft  part thereby arbitrarily changing the oscillation amplitudes of the mold. CONSTITUTION:The changing of, e.g., amplitude amount, by this driving device for mold vibration is accomplished by the following method. Namely, a ring gear 34 is turned by a hydraulic  cylinder 36 by way of a lever 38. Next, the revolution given to the gear 34 is acted upon the  planetary gear 19 only and a sun gear 13 is rotated by the rotation of the gear 19. Further the  eccentric sleeve 6 integrated therewith is rotated, whereby a change is given to the phase of the rotating direction of the sleeve 6 and eccentric shaft part 4. Hence, the combination of the eccentric amount of the sleeve 6 and shaft part 4 is changed by the specified amount within the  range from the maximum to minimum amounts, whereby the eccentricity amount with respect to  the output shaft 2 of the sleeve 6, in other words, the amplitude amount of the connecting rod 9  and mold vibrating frame may be changed. After the position changing of the gear 34, the sleeve  6 and shaft part 4 are synchronously revolved in the state where their phase is maintained, whereby the mold vibrating frame is vibration-moved at the changed amplitude.
