Title: Method and device for leak detection of stop valve at steam turbine plant or the like
Inventor: SOUMA AKIO
IPC: G01M3/04
Filed: 1979-06-06
Abstract: PURPOSE: To secure the assured detection for the leak of the stop valve, by giving a comparison between the inside temperature of the condenser which is connected to the high-temperature fluid generator via the main pipe and the inside temperature at the down-stream side part of the stop valve of the branch tube which is connected to the main pipe and the condenser each.  
     CONSTITUTION: In the steam power generation plant, the high-temperature and high-pressure steam generated from steam generator 1 is led to turbine 4 via main steam tube 2 and main steam stop valve 3 each in order to give the operation to power generator 5. The steam which had the job at turbine 4 and turned to the low temperature and pressure is condensed at steam condenser 6, and the condensed water is returned to generator 1 through condenser tube 7. Both tube 2 and condenser 6 are connected by branch tube 9 and via stop valve 10. Valve 10 is closed under operation. Then a comparison is given through temperature arithmetic unit 13 between the inside temperature of condenser 6 measured by thermometer 11 and the inside temperature at down-stream side part 9b of valve 10 measured by thermometer 12 respectively. And the result of comparison is displayed on display unit 14. As a result, the leak of valve 10 can be detected assuredly.

Title: Manufacture of strip plate with dissimilar width
Inventor: MATSUSHITA TOMIHARU
IPC: B21H8/00
Filed: 1986-03-27
Abstract: PURPOSE:To easily manufacture with good yield the dissimilar width strip plate of a spring material having high plate thickness accuracy, etc. by rolling the dissimilar diameter wire rod having different sectional shape in the axial line direction. CONSTITUTION:The dissimilar diameter wire rod 11 that a small diameter shaft part 12 and large diameter shaft part 13 are formed in succession periodically via a taper shaft part 14 is prepared in case of manufacturing the dissimilar width strip plate of a spring stock, etc. Such wire rod 11 can easily be subjected to a drawing by drawing with heating locally the wire rod stock in the same diameter with that of the wire rod 11. A dissimilar width strip plate 1 is then formed by rolling this wire rod 11 with a horizontal two step roll. Consequently the yield becomes extremely high because of all the wire rod 11 being utilized. The strip plate of high plate thickness accuracy can easily be manufactured since there is no need for the adjustment of the roll gap over the wide width like in a plate rolling.

IPC: G02B6/26
Filed: 1980-05-27
Abstract: PURPOSE:To prevent cross-talk by cutting off leakage light incident to the end surface of a cladding layer, by providing a light-shielding film, covering the end surface of the cladding layer, between the counter terminal surfaces of a multicore optical fiber. CONSTITUTION:In the end surface of a multicore optical fiber 22, a light-shielding film 34 is formed on the end surface of a cladding layer 25. Such a fiber 22 is used for an optical connection with the other multicore optical fibers 21 by making their connection end surface face to each other. Consequently, part of light transmitted in one fiber 21, even if emitted to an end surface part other than core parts 24a-24c of the other counter fiber 22 at the connection part, is shielded from by the light- shielding film 34. Thus, the leakage light is intercepted by the light-shielding film 34, so the generation of cross-talk is prevented.

Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To improve reliability and productivity of a semiconductor package mounted on small portable equipment, etc., by forming ruggedness on the surface of an organic resin which covers an IC chip for protection. SOLUTION: The reliability and the productivity of a semiconductor package mounted on small portable equipment, etc., are improved by manufacturing the semiconductor package, through roughening the surface of an organic resin 4 such as polyimide, which covers the surface of an IC chip for protection, connecting the IC chip 9 to a circuit board 10, and encapsulating the surface of the IC chip with a liquid encapsulating resin 12. Since the structure of the semiconductor package has ruggedness on the organic resin 4 of the IC chip 9, adhesion between the organic resin 4 and the encapsulating resin 12 is strengthened, and moisture resistance is improved. Since the roughening process is performed in the wafer status, the batch-process of the surface of the IC chips can be performed. The surface can be easily roughened to have ruggedness by reactive ion etching.

Abstract: PURPOSE:To improve the accuracy of measurement and the efficiency of decision by utilizing the data of respective channels relatively to each other to make element decision of peaks. CONSTITUTION:The X-rays released from an excited sample S are split to 3 wavelength areas. Spectroscopes 1, measuring systems 2 and memory devices 3 are provided to the respective three channels and the detected data are stored in the memory devices 3. The main peak of one channel is screened and the auxiliary peak corresponding to the element of that peak is screened over the entire channel. Decision is made that the element corresponding to the corresponding auxiliary peak is included in the sample if said peak exists. The peak appearing at said element is then excluded from the decision peak group. The main peak is selected from the undecided peak group with respect to another channel and is subjected to the same processing. Such processing is sequentially executed with all the channels and, therefore, the accuracy of the measurement and the efficiency of the decision are improved.
