Title: Resist composition
Inventor: KODACHI AKIKO
IPC: H01L21/30
Filed: 1989-01-20
Abstract: PURPOSE:To obtain the electron resist having high sensitivity by using the copolymer of the acrylic ester substd. with an electron-withdrawing group of an alpha position or acrylonitrile and silicon-contg. methacrylic ester as a constituting component. CONSTITUTION:A reason for the poor sensitivity of the methacrylic ester expressed by the formula I lies in that the methyl group (Me) is not the electron- withdrawing group. The sensitivity thereof can be enhanced simply by using the copolymer of the acrylic ester substd. with the electron-withdrawing group of the alpha position or acrylonitrile. The monomer substd. with the electron- withdrawing group in the alpha position is liable to decompose when the monomer is made into a polymer by irradiation of electron beams. Namely, the bond of the main chain weakens as the electrons are absorbed in the direction of the alpha position. The high-sensitivity positive type resist is obtd. while the oxygen (O2) dry etching resistance are maintained by providing the high decomposability.

Filed: 1990-01-24
Abstract: PURPOSE: To prevent the jumping of the picture content of inserted character signals against the picture content of display picture signals by generating a starting pulse edge for a character generator from a controller when the same line pulse is always detected. CONSTITUTION: A line pulse extracted form picture signals is also supplied to a controller 25. The controller 25 is provided with a detector 35 which always detects the same line pulse in reproduced picture signals and, when the detector 35 always detects the same line pulse, generates a starting pulse edge for a character generator 23. Accordingly, the display of the picture content of inserted character signals on the screen of a television receiver is always started from the same line of the picture content of picture signals reproduced from a recording medium. Therefore, the jumping of the picture content of inserted character signals against the picture content of reproduced picture signals can be prevented.

Filed: 1979-02-07
Abstract: PURPOSE: To exactly confine harmful susbtances as well as treat sludge in great quantities simply by the procedure in which sludge, particularly from leather processing factory, is fused by heating to treat it as fused solid.  
     CONSTITUTION: Sewage sludge containing leather waste water or great quantities of calcium and leather waste water sludge are mixed with the incineration ash of urban refuges and then fused by heating. In this case, the preferred mixing ratio of the urban refuges incineration ash to the sludge is 0.2W2 on the basis of the ash 1 of the sludge. Thus, the melting point of the mixture is lowered and thereby the heating and fusing treatment of the sludge made easier. In addition, heat quantity necessary for the treatment is saved and also harmful susbstances are confined.
