Title: Colored light-shielding spacer for liquid crystal and liquid crystal display element
Inventor: YAMAKADO NAGAHIKO
IPC: G02F1/1339
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To obtain a uniform colored light-shielding spacer which has high strength and enough light-shielding performance but does not cause contamination of a liquid crystal by coloring agent, by allowing a carbon black to intrude and impregnate specified crosslinking polymer fine particles before a crosslinking process and then fixing the carbon black in a crosslinking process to obtain carbon black-contg. crosslinked polymer fine particles. SOLUTION: A carbon black is added to a reaction slurry containing polymer particles which are obtd. by a precipitation polymn. method and are not crosslinked yet, so as to bring the polymer fine particles into contact with the carbon black to impregnate the particles. Then a catalyst which accelerates hydrolysis of hydrolytic silyl groups to form siloxane bonds, such as hydrochloric acid, sulfuric acid and potassium hydroxide is added to the slurry containing the polymer fine particles impregnated with the carbon black so as to accelerate crosslinking. Thus, colored crosslinked polymer fine particles are obtd. A light- shielding effect is obtd. by the carbon black which is made to intrude and impregnate the polymer fine particles.

IPC: B05D1/40
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To apply a slurry liquid contg. phosphor on the surface of an Si substrate by a slurry method without forming a dead space. SOLUTION: This method consists in arranging a circumferential substrate 6 along the outer periphery of the Si substrate 2. The height of the circumferential substrate 6 is set equal to or lower than that of the substrate 2 in such a manner that the build-up part 4 of the slurry liquid 1 contg. the phosphor is not formed on the surface edge of the Si substrate 2 by surface tension. The slurry liquid 1 is spread and applied by centrifugal force on the surface of the rotating Si substrate 2 in such a manner that the slurry liquid 1 applied on the Si substrate 2 and the slurry liquid 1 applied on the circumferential substrate 6 form the continuous same layer.

Abstract: PURPOSE:To measure easily and accurately the phosphorus compd. in the sample water by passing ozone to decompose the phosphorus compd. in the acidic sample water under heating to PO<-3>4 through the acidic sample water. CONSTITUTION:A specified amt. of the sample water is pumped 2 from a sampling pipe 1 and is injected into a reaction vessel 8 by opening a valve 19. The aq. acid soln. 3 in an acid tank 4 is then dropped into the sample water drawn into the vessel 8 by using a pump 5 and opening a valve 20. Then, the vessel 8 is heated by a heater 8 and valves 19, 20 are closed to feed the ozone into the vessel 8. The acidic sample water 21 of which the phosphorus compd. is oxidized and decomposed to PO<-3>4 is conducted into a receiver 10 and is fed by a pump 11 to a filter cylinder 12; thereafter a color forming agent 13 in a tank 14 is added by a pump 15 to the sample water. Then the mixed sample water 21 arrives tat a mixing and color forming pipe 16 so that the sample water forms the color. The sample water is then conducted to an absorption meter 17 by which the absorption quantity is measured. The measured quantity is recorded by a recorder 18 and the concn. of the PO<-3>4 is determined from a calibration curve. The total phosphorus concn. in the sample water is calculated therefrom.

Title: Dry etching method for insulating film
Inventor: OKANO HARUO
IPC: H01L21/302
Filed: 1990-10-02
Abstract: PURPOSE:To anisotropically etch an insulating film selectively with reference to a substratum material whithout forming a contamination layer on the substratum material by a method wherein the insulating film is etched by utilizing the difference in electronegativity between the insulating film to be etched and its substratum. CONSTITUTION:An insulating film is etched by utilizing the difference in electronegativity between the insulating film to be etched and its substratum. That is to say, H2SO4 as a liquid is generated on a substrate 13 to be treated; HF gas generated by a reaction of H2O with SF6 is dissolved by H2SO4; H<+>, F<->, HF2<->, and the like are generated. These ions are reacted with SiO2 but are not reacted with Si so much. As a result an SiO2 film 2 is etched by an ion impact and by a reaction with ions, and an Si substrate 1 is hardly etched. Thereby, the insulating film 2 of SiO2 or the like can be anisotropically etched selectively with reference to a substratum material without forming a contamination layer such as a fluorocarbon film on the substratum material such as the Si substrate 1.
