IPC: F23C13/00
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To provide a compact combustor from which clean combustion gas is discharged, by performing complete combustion. SOLUTION: The discharge port 5a of the combustion chamber 5 of a combustor 30 is provided with a contact part 20 which is equipped with a contact member 21 where a hole 25 is opened at the center and a contact member 22 where a plurality of holes 26 are opened at the periphery, and a catalyst layer 31 is made at the face on the side of the combustion chamber.

Title: Noise processing method for magnetic bubble memory device
Inventor: CHIBA SHINSAKU
IPC: G11C11/14
Filed: 1981-01-14
Abstract: PURPOSE:To surely reject adverse effect due to noise in a detector output, by skipping a minor loop affected by the noise due to a function pulse during detector operation period. CONSTITUTION:Noise due to a function pulse during operating period of a detector 12 is introduced by electrostatic or electromagnetic coupling to detectors 12, 13. This noise is applied to an input terminal of a sense amplifier 20 via coupling capacitors 16, 17. On the other hand, an output signal ''1'' corresponding to unbalanced component of noise induced to the detectors 12, 13 is given from an output terminal 20a of the amplifier 20 for the noise to the detectors 12, 13. The signal is set with a clear pulse Pcre during the data readout period, although it is inputted to a set input of an FF21, and a detection signal ''0'' is outputted from an output terminal 21a of the FF21. Thus, the adverse effect due to noise is surely rejected.

Title: Fluorescent x-ray analysis apparatus and composite artificial multilayered film body
Inventor: SUDO MASAAKI
IPC: G01N23/223
Filed: 1990-01-12
Abstract: PURPOSE:To improve the reflection intensity and half-amplitude level of fluorescent X-rays by utilizing the phenomenon that the composite artificial multilayered film body selectively reflects the X-rays of the wavelength regions varying from each other. CONSTITUTION:The composite artificial multilayered film body 7 consists of a substrate 16 subjected to super polishing and a film forming part 17. The film forming part 17 has the multilayered films 18, 19, 20. A sample 3 is first held and the interior of a casing is evacuated. A controller 15 impresses a signal SR to a driving mechanism 14 to turn an angle measuring instrument 11 and sets a diffraction angle theta at the multilayered film body 7. The sample 3 emits the fluorescent X-rays 5 when an X-ray tube 1 makes primary X-rays 2 incident on the sample 3. The fluorescent X-rays 5 are made incident through a solar slit 6 on the multilayered film body 7 held on a stage 21 and are spectrally divided. The X-rays 8 of the specific wavelength converted to the monochromatic X-rays are made incident on an X-ray detector 9. The controller 15 monitors a signal SC and applies the signal to a motor 23 to move the stage 21 in an arrow 12 direction. The incident position of the fluorescent X-rays 5 is then changed in order of the films 18, 19, 20. The controller 15 can, therefore, select the multilayered films to minimize the half-amplitude level and make the element analysis of the sample 3 by the X-rays 8.

IPC: E02D27/01
Filed: 1995-01-12
Abstract: PURPOSE: To lighten the weight of a form with the thickness reduced for its face plates without weakening its strength. CONSTITUTION: A form 1 for concrete placing has a face plate 2 for forming concrete in a specified shape, and reinforcing ribs 14, each made up by bending a thin steel plate into a shape in L-shaped section, are connected and fixed in X-shaped forms to the reverse side of the face plate 2 while auxiliary reinforcing ribs 15 are connected and fixed vertically and transversely to the reverse side. A trussed structure is formed with the reinforcing ribs 14 and peripheral edges of the face plate 2 or the auxiliary reinforcing ribs 15, and strength for the entire face plate 2 is improved therewith. Therefore, the thickness of the face plate 2 can be reduced without weakening the strength, and thereby overall weight of the form 1 for concrete placing can be reduced.  Simplicity of structure for the reinforcing ribs 14 and the auxiliary reinforcing ribs 15 and easiness of processing therefor also result in reduction of overall weight for the form 1 for concrete placing.

Title: Image forming machine
Inventor: TANAKA ATSUSHI
IPC: G03G15/16
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To repeatedly obtain a high-quality image over a long period, without a missing image by making the resistance value of an intermediate transfer belt, Young's modulus in a peripheral direction and the microhardness of an image carrying surface specific values respectively. SOLUTION: When an image formed on a first image carrier is transferred to the intermediate transfer belt and then, onto a second image carrier, the resistance value of the intermediate transfer belt is 1×10<4> -1×10<11> Ω, Young's modulus in the peripheral direction is >=1×10<7> Pa and the microhardness of the image carrying surface is <=90 deg.. Since the resistance value of the intermediate transfer belt is made the above-mentioned value, a high grade image can be obtained without the harmful influence of the fact that a target tone image can not be obtained. Since Young's modulus and the microhardness of the image carrying surface are made the above-mentioned values, reduction in the tensile force of the intermediate transfer belt does not appear as a practical harmful influence, even if repeated use is attained.  Thus, the image without a void can be obtained.

Title: Ink occluding member
Inventor: SAKANISHI YUTAKA
IPC: B41J31/16
Filed: 1993-01-13
Abstract: PURPOSE:To eliminate the leakage of ink, the blur at the time of printing, the lowering of printing life and the generation of printing density by setting the ratio of the amt. of the ink infiltrated in an ink occluding member and the total surface area of the fibers in the ink occluding member to a specific range. CONSTITUTION:An ink occluding member is produced so that the ratio of the amt. m(g) of the ink infiltrated in the ink occluding member and the total surface area M(cm<2>) of the fibers in the ink occluding member satisfies the range represented by formula I. The total surface area S of the fibers is calculated from the volume or density of the ink occluding member or the denier or density of the fibers constituting the ink occluding member. When the range represented by the formula is set, ink uniformly spreads to the interstices between the fibers of the ink occluding member when a definite time is elapsed after the ink is infiltrated in the ink occluding member and the ink is held on the surfaces of the fibers in a storable amt. By this constitution, a proper amt. of the ink can be always infiltrated in the ink occluding member and the leakage of the ink or the blur at the time of printing caused by the excessive or too little impregnation amt. of the ink can be eliminated.
