Title: Method of attaching grid to frame of color cathode ray tube
Inventor: TAWARA MINORU
IPC: H01J9/14
Filed: 1990-08-08
Abstract: PURPOSE:To prevent wire-rod grids from being cut off when they are fixed by welding or the like, by heating wire-rod grids and at the same time fixing both ends of the respective wire-rod grids to the frame in the state of a certain deformation being applied to the frame when the wire-rod grids are fixed. CONSTITUTION:A tensile force is applied to wire-rod grids 4 by a weight. The weight weighs to some degree that the grids 4 are not cut off during the process of welding and wire rods being lightly tensile. A hot blast is applied to the grids 4 to heat them so that the grids 4 are in the state of elongation from the state at a normal temperature due to linear expansion by heat. Nextly, the main beam 1 is bent inside and the deformed state of the main beam 1 is kept. As the grids 4 are touching the upper surface 3 of the main beam 1 of the frame, the lower surface of the grids 4 is welded to the upper surface 3 of the main beam 1 of the frame in the deformed state. After the fixing process of the grids 4 is completed, when the temperature of hot blast is returned to its normal temperature, the wire rods 4 stretched due to linear expansion may contract since their temperature is returned to a normal temperature. After that, pressing bolts 18 are loosened but the main beam 1 keeps an amount of flexure delta, and also the wire rods 4 keep the tense state due to contraction.

Title: Fuel supply device
Inventor: NOGI TOSHIJI
IPC: H04R17/08
Filed: 1987-08-24
Abstract: PURPOSE:To increase a measurable flow rate range of fuel, and improve the atomization function thereof by applying, to an piezoelectric element, two pulse driving signals which are synchronous with the resonance frequency of a horn and have two different amplitudes. CONSTITUTION:Two pulse driving signals which are generated synchronously with the resonance frequency of a horn 1, provided on an intake pipe 4, and have two respective different amplitudes are applied to a piezoelectric element 5 which drives the horn 1 to make displacement. Therefore, the horn 1 always oscillates with the resonance frequency to atomize fuel at all times. When the first pulse driving signal with a smaller amplitude is applied, the fuel is not jetted because a jet hole 21 is blocked with a ball 8. The second pulse driving signal with a larger amplitude is then inserted therein by a driving signal supply means at a specified interval. The oscillation of the horn 1 is enlarged accordingly, so that the jet hole 21 is opened because the ball 8 is detached therefrom. As a result, the fuel is jetted while the flow rate thereof is controlled according to the pulse width.

Title: Solidification treatment of radioactive waste
Inventor: MATSUURA HIROYUKI
IPC: G21F9/16
Filed: 1990-08-09
Abstract: PURPOSE:To enable producing a solidified body which is faborable for safety evalution by adding a quick lime or a slaked lime to powder waste body in order to solidify it, after addition of carbonate ion to the extent that exceeds the saturating solubility of a calcium carbonate, to the powder waste body. CONSTITUTION:Soluble carbonate ion having been existing in a condition of a sodium carbonate in dry powder waste body, dissolves, for the first time, as a sodium carbonate into water, when a plastic solidified body gets in contact with the water. At the same time, a quick lime or a slaked lime dissolves into water, reacts with the sodium carbonate to change itself to a calcium carbonate and to an almost insoluble condition into water. However, since the amount of the carbonate ion containing a radioactive nuclide, C-14, is extremely small, the carbonate ion reaches its solubility and there is some possibility for the ion to dissolve into water. Accordingly, a sodium carbonate is added to the extent well to exceed the solubility of the calcium carbonate, and therewith the carbonate ion containing the nuclide, C-14, co-percipitates with the added carbonate ion and can be changed to an almost insoluble one into water. Finally, by plastic solidification, leaching-out of the carbonate ion can be remarkably reduced.

Title: Control system for keyboard interface
Inventor: ISHIKAWA TAKESHI
IPC: H03M11/20
Filed: 1987-08-25
Abstract: PURPOSE:To reduce the processing load for a data processing unit by carrying out the scan and the reception control only when a key operation part or a keyboard unit is operated and after the data processing jobs carried out by those key operations become idle. CONSTITUTION:When the keys are operated at a key operation part, a microcomputer CPUS scans the key operation part and receives the key operation information as long as a keyboard unit 3 is not processing data. Then keys are operated via the unit 3 and therefore the unit 3 is controlled by the processor CPUS as long as the key operation part is not processing data. At the same time, the information on the key operations of the unit 3 are received. Thus the data processing load is reduced for a data processing unit 6 by carrying out the data processing only when the keys are operated at the key operation part with no usual accesses given to the key operating part.

IPC: B22D18/06
Filed: 1992-07-13
Abstract: PURPOSE:To prevent the opening movement of a mold during casting and to simply and surely form a sealing structure between a molding flask and a molding board. CONSTITUTION:In a suction casting apparatus for sucking molten metal into a cavity 12k by covering the molding flask 14 surrounding the mold 12 to the mold 12 laid on the molding board 16 and reducing the pressure in the molding flask 14 to indirectly reduce the pressure in the cavity 12k in the mold 12, an upper plate 14t of the molding flask 14 is made of a heat resistant rubber plate. By this method, at the time of reducing the pressure in the inner part of the molding flask 14, the upper plate 14t is deformed downward and abutted on the upper surface of the mold 12. By this result, on the upper surface of the mold 12, the force caused by differential pressure between the inside and the outside of the molding flask 14 is applied downwards, and therefore, the opening movement of the mold during the casting is prevented. Further, as the molding flask 14 is unnecessary to be shifted to the molding board 16 during the casting, the simple sealing structure between both can sufficiently be used and the sealing performance is improved.

Title: Dual-port-memory and communication method thereof
Inventor: SAADO AJIZU JIYAMOUA
IPC: G11C8/16
Filed: 1990-08-08
Abstract: PURPOSE: To speed up memory access by communicating data between a read/ write memory and an electronic processor through a multiplex information path. CONSTITUTION: When memory access requests from ports A and B conflict, both read requests have to be satisfied within time corresponding to the shortest read response specification of micro processors 10 and 11 hosted by a common memory. Thus, the most dangerous memory cycle is a read cycle. A data prefetch function can satisfy all the memory access requests in shortest possible time. Thus, the complete transparency of the dual port characteristic of the memory is kept. Thus, increased memory access speed is realized without substantially increasing the cost of the memory. A wait state and handshake technology can be avoided by the host micro processor and high operation efficiency is kept.
