Title: Reactor pressure vessel for large natural circulation reactor
Inventor: SHIBATA SHOJI
IPC: G21C15/02
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To attain smooth cooling water flow along the lower head after going down in a flow path, reduce resistance loss and tunbulence of natural circulation, enhance the strength and reduce the weight by making the opening for cooling water hemispherical shell shape which little disturbs the flow of cooling water. SOLUTION: Cooling water separated in a steam water separator 9 goes down along a cylinder part 3 together with feed water supplied from a water supply pipe 12, passes through an opening 6a for cooling water in a shroud support 6, goes up in the support 6 and is heated when it passes the core in the lower shroud 7a. The cooling water becomes steam when passing through the upper shroud 7b, be separated in the steam water separator 9, dried in a drier 10 and sent to a turbine. As the lower head 4 is made in hemisphere, the cooling water flows along the hemisphere surface and have little direction change and small resistance when passing the opening 6a. Though the flow changes upward when it goes in the support 6 toward the core in the shroud 7a, resistance increase is small because of the change in large volume compared with the cross sectional area of the opening 6a.

Abstract: PROBLEM TO BE SOLVED: To prolong the life of a resistance filament by changing the power factor of an AC circuit in response to the aged change of the resistance of the resistance filament of an electric lamp capable of being selectively connected in series to a power supply. SOLUTION: An inductor 18 is connected in series to the filament 12 of an incandescent lamp 14 applied with public AC power from a power supply 10 via a switch 16.

Abstract: PURPOSE:To obtain one-body constitution of a plane antenna and a frequency converter by allowing the direction of the output terminal of the plane antenna and that of the input terminal of the frequency converter to coincide with each other to constitute them so that the distance between both terminals is shortest and coupling both terminals with a coupling coaxial line. CONSTITUTION:A low noise converter circuit 11 consisting of a microwave integrated circuit is set on an earth conductor plate 5 joined to an earth conductor 4 of a microstrip plane antenna, and a weak RF signal from the plane antenna is coupled to the frequency converter 11 of the low noise converter circuit by a coupling coaxial line 10 to take out an IF signal from an IF output terminal 9. As shown in a figure, a case 12 for the frequency converter 11 is joined with the earth conductor plate 5 into one body and the case 12 is provided with a metallic cover 13. Since the distance between the output of the antenna 1 and the input of the frequency converter 11 is very short and line conversion is reduced by this constitution, the coupling loss is reduced as much as possible and terminals are coupled without equivalently degrading the noise factor of the low noise converter, and the plane antenna 1 and the frequency converter 11 can be joined into one body.

Abstract: PURPOSE:To prevent the erroneous connected of a circuit to be connected with an output terminal or circuit destruction caused by timing deviation, etc., by outputting a dissidence detection signal and making the output impedance of an output buffer circuit high when the data of an input end in the output butter circuit is dissident with the data of an output terminal. CONSTITUTION:During a period Ta, at first, when a data latch signal DL is set in a low level state and the level of an output control signal OC is made high, an output signal DO of a delay circuit 31 is a high level while being delayed only for decade time t1. Accordingly, the level of an output AO from an AND gate 4 is made high and the output buffer circuit 2 is turned to an active state. At such a time, output data DT2 of a latch circuit 1 to be inputted to an exclusive OR gate 32 are compared with data OUT of an output terminal TM. When the data are coincident, a detection signal EO at the low level is outputted and when the data are dissident, the detection signal EO at the high level is outputted. Then, when the data are dissident, the level of a dissidence detection signal UE is made low and the level of the output AO from the AND gate 4 is made low. Afterwards, transistors T1 and T2 of the output buffer circuit 2 are turned OFF so that an over current can be prevented from flowing.

Title: Pattern transfer method
Inventor: FUKAO RYUZO
IPC: B41M3/06
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To directly transfer a pattern to the surface of matter by forming the pattern composed of a pattern forming material on a sheet wherein a polymer film having close adhesiveness is provided on the surface of a flexible film by a printing press and subsequently peeling the polymer film from the flexible film to bond the same to the surface of the matter. SOLUTION: When a pattern is directly transferred to the surface of wood, paint for a release layer consisting of water-soluble polyvinyl acetal and water and a paint for clear coat consisting of a polyester resin, methyl ethyl ketone and toluene are successively applied to a base material film 1 such as a polyethylene terephthalate film and dried to form a film material provided with the release layer 2 and the clear coat layer 3. The end part of the film material is turned over a finger to peel the formed film which is, in, turn, bonded to the surface wetted with water of a wood plate becoming an article to be processed. Since the material of the release layer is a water-soluble resin, it functions as an adhesive to strongly bond the clear coat layer and, since it is an extremely thin film, sufficient close adhesiveness is obtained.
