Title: Method and device for detecting leak place of buried pipe of gas
Inventor: NAKAZAWA SANSAKU
IPC: G01M3/02
Filed: 1985-07-10
Abstract: PURPOSE:To shorten the time until a leak place is detected and to decrease the boring places by replacing an atmosphere in the plural boring holes along a buried pipe with the open air, and then, measuring and comparing the gas concn. after the equal time elapses respectively. CONSTITUTION:In advance of measuring the gas concn. in the plural boring holes 3 (3a-3g) along the buried pipe 1, the atmosphere in the holes 3 is first replaced with the open air. Afterward, the gas concn. after the equal time elapses is measured and compared respectively. In other words, an inflow of leaked gas with respect to the holes 3 is reduced as it becomes distant from the leak place 2. Consequently, an inclination of the gas concn. is detected and the existence of the gas leak place 2 in the neighborhood of the hole 3e with the highest gas concn. is assumed by measuring a change of the gas concn. with respect to the lapse of time after the open air is replaced in each hole 3. Consequently, the gas leak place can be specified in a narrow range even in case a large quantity of gas is leaked and the time until the gas leak place is detected can be shortened and the cost can be reduced by a decrease of the boring places.

Title: Mold for continuous casting
Inventor: HIRASHIRO TADASHI
IPC: B22D11/04
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To promote the supplying of powder into a gap between the solidified shell and the inner surface of a mold, to uniformize the flowing of the powder in the width direction and to obtain further high casting speed by forming plural grooves reducing the depth and the width extended in the casting direction on the inner surface of the mold from a meniscus to the casting direction. SOLUTION: The grooves 23 are formed on the inner surface of the mold from the position corresponding to a meniscus toward the casting direction and the flowing-in of the powder is facilitated by increasing the area of the gap between the inner surface 12 of the mold and the solidified shell near the meniscus. Further, the unevenness of flowing-in of the powder in the width direction developed caused by the difference of the gap between the part formed with the groove and the part without forming the groove, is improved by reducing the width and the depth of the grooves in the casting direction. The formation of the grooves 23 has the effect even only on the inner surfaces of one pair of long side parts in the mold in the case of being the mold for slab, but the application to the whole periphery of the mold is desirable.  The formation of the grooves 23 is desirable to arrange from the upper end 24 of the mold.

Title: Signal reproducing method via composite magnetic head
Inventor: FURUKAWA ISOKAZU
IPC: G11B5/23
Filed: 1978-12-10
Abstract: PURPOSE:To realize the individual reproduction for both the reproduction signal occupying the wide band and the signal occupying only the low frequency band by providing several units of magnetic heads possessing the different magnetic gap lengths to one magnetic head. CONSTITUTION:The windings are turned round cores 2 and 3 possessing magnetic gaps Gn and Gw to form the different magnetic heads. These magnetic heads are then distributed so that the magnetic gaps may be arrayed in the width direction of the record track in order to form the composite magnetic head. The magnetic head featuring narrow gap Gn can reproduce the signals of the wide frequency band; while the head featuring wide gap Gw can reproduce satisfactorily only the signals of the low frequency band. Now in case the signals of the wide band are reproduced, only the head of gap Gn is used. While the heads of both gaps Gn and Gw are used for reproduction of the signals in the low band to obtain the sum signal of the reproduction output. In this way, the signals of both bands mentioned above can be reproduced individually.

Title: Method and instrument for analyzing organic substance for impurity
Inventor: TSUJI MIKIO
IPC: G01N21/73
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To analyze organic substances for impurities with high accuracy in a state where the risk of contamination is reduced without requiring any pre-treatment by performing the drying and ashing of sample solutions in an oxidizing gas atmosphere and vaporizing the products of ashing in an inert gas atmosphere. SOLUTION: After a sample solution 307 is introduced to a sample introducing section by, for example, 100 μm, the sample introducing section is heated up to, for example, 700 deg.C while an oxygen gas containing 1 vol.% ozone is supplied to the sample introducing section from an oxidizing gas cylinder 304. When the sample introducing section is heated, organic components are completely decomposed and removed and the residues of impurities are left in the sample introducing section. Depending upon the composition, flow rate, etc., of the oxidizing gas, the decomposition and removal of the organic components end within several minutes. When the decomposition and removal end, the impurity components are vaporized while Ar gas is introduced to the sample introducing section as an inert gas by operating a gas change-over valve 306 and the vapor is analyzed by atomic absorption.  Therefore, all treatment performed on the sample from the decomposition and removal of the organic components to the analysis of the impurity components can be executed in the sample introducing section only.
