Title: Picture retrieving system
Inventor: HIRASAWA AKIRA
IPC: G06F17/30
Filed: 1988-12-09
Abstract: PURPOSE:To efficiently retrieve a necessary picture by executing arithmetic by area information to show an attention area and a coordinate value, which is given as a retrieval condition, and determining the picture of a retrieved result based on an arithmetic result. CONSTITUTION:A picture retrieving part 12 receives data concerning the respective retrieving pictures from a data housing part 13 and retrieves the picture and the picture of a retrieved number is taken out of a picture housing part 12 and sent to a picture display part 11. In the picture display part 11, the transferred picture is displayed. In the picture retrieving part 12, concerning one housing picture, a coordinate value (Xw,Yw) in the center of gravity for one rectangle is controlled at every retrieval subject picture. When the picture is retrieved and for example, a point (Xs,Ys) is given as the retrieval condition, a distance {(Xs-Xw)<2>+(Ys-Yw)<2>}<1/2> between this point (Xs,Ys) and the center of gravity in the attention area is obtained for all the pictures. Then, the picture, for which this distance is the smallest, is defined as the retrieved result. Thus, the necessary picture can be efficiently retrieved.

IPC: F25B41/06
Filed: 1991-11-27
Abstract: PURPOSE:To improve efficiency of a nozzle by providing one or more throttling means upstream of a nozzle of a pressure reducing device to allow a fluid to pass through said means in such a manner that the fluid is in a state of low compressibility, thereby reducing the pressure thereof, so that the fluid is kept in a gas-liquid two-phase state at the entrance of the nozzle. CONSTITUTION:An ejector 4 comprises a first nozzle 4a for reducing the pressure of liquid refrigerant R1 introduced from a refrigerant condenser 3, a second nozzle 4b for blowing off the refrigerant whose pressure has been reduced, and a diffuser 4c for diffusing the refrigerant. The pressure of high pressure liquid refrigerant R1 condensed at the condenser 3 is reduced at the nozzle 4a so that the refrigerant R1 is turned into a refrigerant R2 of gas-liquid two-phase, which is blown off from the nozzle 4b and mixed with a gas refrigerant R4 drawn from a suction port 4d and the pressure of the mixture is raised at the diffuser 4c. The refrigerant is separated into gas refrigerant and liquid refrigerant at a separator 5 to send the former R7 to a compressor 2 and the latter R6 to an evaporator 6. By reducing the pressure of the liquid refrigerant to expand it at the nozzle 4a, thereby turning the refrigerant into a two-phase state at the entrance of the nozzle 4b, nozzle efficiency is improved and suction capacity of the ejector 4 is increased.

Title: Manufacture of sheet-like cast molding and apparatus therefor
Inventor: UMEHARA SHUNJI
IPC: B29K101/10
Filed: 1992-10-27
Abstract: PURPOSE:To eliminate the cracking strain or distortions of sheet-like molding by arranging oppositely a pair of molds having a larger heat capacity than the heat capacity of a molding and a smaller linear expansion coefficient than the linear expansion coefficient of a molding, and by performing mold opening while blowing pressurized air into between both molds during the mold releasing period. CONSTITUTION:An epoxy resin material of the order of 50g in weight is poured between a pair of right and left glass-made molds 5 held by vacuum pads 4, and after heated within an oven, it is taken out in a room temperature circumstance. Accordingly, the heat capacity of the molds 5 is greater than that of a resin molding 16, and the linear expansion coefficient becomes smaller than that of the molding. Then, pressurized air is supplied from the nozzle 8 of an uplift pressure supplier 6 secured on the upside of both the molds 5 with the consequence that the molding 16 and molds 5 are cooled successively from their upper part so that inner stress is generated which tends to contract inward within the molding thereby the molding 16 is separated from the molds 5 gradually and mold opening is completed when the molding 16 is made separating from the face of the molding 16 generally. Therefore, the molding 16 can avoid the occurrence of cracks or distortions even in the form of its sheet-like configuration.

Title: Method and apparatus for interference exposure
Inventor: TAKAHASHI KOJI
IPC: G02B5/18
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To reduce the degradation of diffraction gratings due to uneven exposure by providing a prism that has antireflection coating on a first face in contact with a photosensitive film of a wafer and on second and third faces adjacent to the first face and opposite each other. SOLUTION: Light entering through a face 601 (602) of a rectangular prism having corners ϕ, ϕ' of 90 degrees is reflected by a face 602 (601) and directed to a face 603 for exposure. If the faces 601 and 602 have an antireflection coating to reduce reflection, the unevenness of exposure is reduced, with the result that the quantity of light required to expose resist decreases 15%. If the face 603 also has an antireflection coating, 30 more percent of exposure light is saved. In addition to the increase in exposure efficiency, therefore, it is possible to improve throughput and prevent the degradation of diffraction gratings due to uneven exposure.

Title: Color cathode-ray tube device
Inventor: UEDA YASUYUKI
IPC: H01J29/50
Filed: 1992-11-24
Abstract: PURPOSE:To enable high resolution to be obtained over the whole area of a phosphor screen. CONSTITUTION:The first constant focusing voltage is applied to the first focusing electrode 3 and the third focusing electrode 6, while the second focusing voltage higher than the first focusing voltage and giving a gradual rise according to an increase in the deflection angle of an electron beam, is applied to the second focusing electrode 5 and the fourth focusing electrode 7. The first electrical field of an axially asymmetrical lens divergent in a horizontal direction but convergent in a vertical direction is generated between the second focusing electrode 5 and the third focusing electrode 6, while the second electrical field of an axially asymmetrical lens convergent in a horizontal direction but divergent in a vertical direction is generated between the third focusing electrode 6 and the fourth focusing electrode 7. In addition, the third electrical field of an axially asymmetrical lens for weakening a focusing effect in a horizontal direction and intensifying the effect in a vertical direction is generated between the fourth focusing electrode 7 and a final accelerating electrode 8. Furthermore, when a horizontal focusing effect due to all of the first, second and third electrical field of an axially asymmetrical lens is kept at A, and the focusing effect in a vertical direction is kept at B, the values of A and B are made approximately equal to each other with the deflection angle of an electron beam kept at zero. Also, a relationship of A>B is established, as the deflection angle increases. As a result, the spherical aberration of a main lens in a horizontal direction becomes small and high resolution characteristics can be provided, even when a large amount of beam current flows.
