Title: Formation of phosphor screen
Inventor: MOTOMURA TOSHIRO
IPC: H01J9/227
Filed: 1986-05-28
Abstract: PURPOSE:To prevent heterochromatic luminous phosphor powder from sticking to a pattern, by processing the substrate formed with the specified pattern within an alkaline gas ambience after a removal process for the phosphor powder of an undesired part at every heterochromatic luminance phosphor. CONSTITUTION:For example, red luminous phosphor powder 14 is fed to a part, where stickiness comes out, ans stuck thereto. Afterward, residual superfluous phosphor powder 14' is removed by means of air processing, forming a phosphor pattern 15 on a photo sensitive adhesive layer 11. At this state, hygroscopicity still remains in an exposure part of this adhesive layer 11 so that moisture comes out to a surface of the phosphor pattern 15, thus there is stickiness anyway. Therefore, after formation of the phosphor pattern 15, a substrate on which this phosphor pattern 15 is formed is set up within an ambience of ammonia gas. With this ammonia gas, hygroscopic material formed in the exposure part of the adhesive layer 11 is chemically converted into nonhygroscopic material, extinguishing the stickiness in the exposure part. With this constitution, heterochromatic luminous phosphor powder is in no case stuck to the phosphor pattern 15.

Abstract: PURPOSE:To stably realize the virtual reflection factor by a method wherein a first film, whose film thickness is lambda/4 of the oscillation wavelength and refractive index is n1, is adhered on one end surface of the resonator mirror of a luminescent element and a second film, whose film thickness is lambda/4 as well and refractive index is n2 smaller than the n1, is adhered thereon. CONSTITUTION:This semiconductor luminescent device has been so constituted that non- reflected films 3 and 4 of two layers, whose film thicknesses t3 and t4 are respectively lambda/4 of the oscillation wavelength, are coated by an electron beam evaporation instead if conventional non-reflected films and the relation between the refractive indexes n3 and n4 of the non-reflected films 3 and 4 is n3>n4. The edge-reflection factor R becomes the minimal value when the film thicknesses t3 and t4 are lambda/4. According to this device constituted in such a way, when the non-reflected films 3 and 4 of n3=3.2 and n4=1.45 are used for lambda-8,000Angstrom , the edge-reflection factor R becomes R=2.2% and an almost same edge-reflection factor as in the case of a non-reflected film 2 of one layer, whose film thickness is lambda/4 of the oscillation wavelength, made of an Al2O3 can be realized, thereby enabling to improve remarkably the noise characteristics in case there is a return light. The film of n3=3.2 and the film of n4=1.45 can be realized by successively coating an alpha-Si (amorphous silicon) and an SiO2 according to an electron beam evaporation.

Abstract: PURPOSE:To enable an oil-immersed electrical equipment to be controlled and observed with respect to internal conditions thereof by means of a single type of ultrasonic sensors, by providing ultrasonic sensors at predetermined positions on the wall of a tank for detecting a temperature of the insulating oil. CONSTITUTION:Ultrasonic waves emitted by an emitter of an ultrasonic sensor 10 provided in each oil stop valve 14 on the wall of a tank 7 are reflected by a core clamp 15 and detected by a receiver of the ultrasonic sensor 10, whereby a propagation time of the ultrasonic waves, namely a propagation speed at which the detected ultrasonic waves are propagated in oil can be calculated. The signal detected by the ultrasonic sensor 10 is averaged by an arithmatic and logic section 12 and outputted from an output section 13. The output indicating the oil temperature is utilized as a control signal for controlling a cooling system 9. Since the receiver of the ultrasonic sensor 10 can detect sound of partial discharge caused by any abnormal condition within the transformer, the transformer can be observed with respect to abnormal conditions possibly occurred therein by detecting such internal partial discharge. In this manner, the oil-immersed electrical equipment can be not only controlled but also observed with respect to its internal conditions by a single type of ultrasonic sensors.
