Title: Overflow-type heat exchanger
Inventor: TAKAHASHI MASATO
IPC: F28B5/00
Filed: 1988-03-24
Abstract: PURPOSE:To reduce thermal stress and previously prevent stress corrosion cracking from occurring, by a construction wherein a vapor-discharging pipe for discharging the vapor into drain water condensed from the vapor and stored in a shell is connected to the inner end of a vapor inlet pipe for introducing the vapor into the shell. CONSTITUTION:A high-temperature vapor conducted by a vapor inlet pipe 12 is conducted into a vapor-discharging pipe 17 through an inner end part of the inlet pipe 12 immersed in drain 16 in a shell 11, and the drain is simultane ously sucked in through a water suction pipe 17c to cool the high temp. vapor. The drain 16 is cooled also by a plurality of cooling pipes 14 immersed in the drain 16, so that the vapor discharged into the drain 16 can be cooled. Since the vapor discharged into the drain 16 is condensed through cooling by the drain 16 and is then led into an upper space in the shell 11, it is possible to contrive a reduction in thermal stress induced in the inner wall of the shell 11 and structures therein, such as the cooling pipes 14, and stress corrosion cracking can be prevented from occurring.

Title: Method for continuous analysis of nickel (ii) ion and iron  (iii) ion
Inventor: SHIRATO FUSAO
IPC: G01N21/75
Filed: 1986-03-28
Abstract: PURPOSE:To rapidly measure the compositional ratio of a liquid to be inspected in which a nickel (II) ion and an iron (III) ion coexist with high accuracy, by introducing the liquid to be inspected into an analytical system in a state sandwiched by a reagent solution and promoting chemical reaction in a reaction system under a high temp. and high pressure condition. CONSTITUTION:A reagent 7 for measuring the sum quantity of a nickel (II) ion and an iron (III) ion and a reagent for measuring the concn. only of the nickel (II) ion are arranged to both sides of a liquid 9 to be inspected and properly used by operating a change-over valve 10 corresponding to an analytical purpose. The reagent 7 or the reagent 8 is sent to each loop of a specimen/ reagent introducing device 6 by a pump 11 simultaneously with the liquid 9 to be inspected and the definite quantity thereof is held. The liquid 9 to be inspected is sent to a reaction coil 3 by a carrier liquid 1 and the reaction product is supplied to an absorption photometer 14 to measure absorbancy and discharged as a waste liquid 17. The detection signal of the photometer 14 is converted to the concn. of nickel or the concn. of iron by a data processing unit 16.

Title: Electron beam device
Inventor: ITO AKIO
IPC: G01R19/00
Filed: 1989-03-20
Abstract: PURPOSE:To remove a contaminant and to improve the voltage measurement accuracy of a sample by injecting reactive gas for etching the contaminant produced on the sample to the sample by a gas injecting means. CONSTITUTION:The reactive gas O2 passes through a constant leak valve 21 and is injected to the sample 12 nearby an electron beam irradiation position from a nozzle 24. As the contaminant is produced on the sample 12, the secondary electron detection signal S of a secondary electron detector 18 drops in level. While the signal S drops in level, the extent of opening of the valve 21 is increased stepwise. Then when it is decided that the signal S increases in level, the extent of opening of the valve 21 is fixed. This means that an etching speed is faster than the production speed of the contaminant and even when the flow rate of O2 is fixed, the etching advances, so that the level of the signal S returns to the level at the start of beam irradiation. Thus, the contaminant on the sample 12 can be removed completely and subsequent long- time measuring operation is stably performed.

Filed: 1982-04-24
Abstract: PURPOSE:To obtain a transfer film capable of well presenting half tone and suitable for heat-sensitive printer by providing plural ink layers of different melting points on the surface of a base material. CONSTITUTION:When supplying an electric current to the resistor 22 of a thermal head through a conductor 23, for example, a heat corresponding to supplied electric current is generated, and a temperature distribution, as shown by dotted lines I (300 deg.C), II (330 deg.C), and III (360 deg.C), for example, is occurred in a transfer film. In this case, if the melting points of the ink layers A, B, and C are 460 deg.C, 380 deg.C, and 300 deg.C, respectively, the ink layers A and B are not melted, the inside portion of the dotted line I in the ink layer C is only melted, and only the light- color ink layer C is transferred to the paper 3 in contact with the melted ink layer. When supplied power is further raised, the ink layers B and C are melted and transferred, and when the temperature in the inside of the dotted line III is raised to 460 deg.C or more, all of the ink layers A-C is transferred to the surface of the paper 3. In this way, a wide range of representation from the light-color layer C to thick-color layer A can be obtained by transfer.

Title: Revolution speed control device for feed water pump
IPC: F01D17/24
Filed: 1992-03-27
Abstract: PURPOSE:To prevent breakage of a feed water pipe by providing a proportional unit to output a regulating valve opening command of a turbine, a setting unit to set the regulating valve opening command and a switch unit to switch an output of the proportional unit to an output of the setting unit. CONSTITUTION:A deviation between a revolution number command 1 of a feed water pump turbine and the actual revolution number 2 of the feed water pump turbine is inputted to a proportional unit 4. After a constant gain is multiplied, an output of the proportional unit 4 is inputted to a switch unit 10. In a normal operation, the switch unit is set on the (b) side, so that the output of the proportional unit 4 becomes a regulating valve opening command. A revolution number increasing rate is detected by a revolution number changing rate computing unit 7 and a revolution number high changing rate signal monitoring switch 8, and the switch unit 10 is set on the (a) side, so that an output signal of a setting unit 9 becomes a regulating valve opening signal 3. Even in an increase of a feed water pump delivery pressure due to a rapid increase in the number of revolutions of a feed water pump, the feed water pump delivery pressure never exceeds the highest working pressure of a feed water pipe. Thereby, breakage of the feed water pipe caused by an increase in the feed water pump delivery pressure can be prevented.
