IPC: C01B31/02
Filed: 1994-11-14
Abstract: PURPOSE: To provide a method for producing a glassy carbon material by which deterioration in productivity is minimized in an HIP treatment; the deformation of a treated material can further be suppressed to prevent the yield from deteriorating due to the occurrence of breakage or cracking and labors required for finishing working such as grinding in the subsequent steps are reduced to afford homogeneous and excellent surface smoothness by grinding. CONSTITUTION: This method for producing a glassy carbon material is to form a thermosetting resin to be the glassy carbon by carbonizing and baking, then previously bake the formed molding at 1000-1800 deg.C temperature in a nonoxidizing atmosphere and subsequently carry out the hot isostatic pressing treatment for applying >=1000atm isostatic pressure at >=2000 deg.C temperature to the previously baked material. The heat-up section of the hot isostatic pressing treatment is divided into the first section extending up to the (previous baking temperature -100 deg.C) under >=1000atm and the second section extending further from the (previous baking temperature -100 deg.C) or above to >=2000 deg.C under >=1000atm. The heat-up rate in the second section is decreased so as to enable the nearly uniform temperature distribution of the previously baked material within 40 deg.C, preferably within 25 deg.C.

Title: Turbine nozzle and boride covering method therefor
Inventor: IKEDA KAZUAKI
IPC: C23C4/10
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To improve erosion resistance by foreign matter in steam by covering a nozzle blade material with a boride layer formed into a thickness having a specified range. SOLUTION: When alumina is flame sprayed into a base metal of a turbine nozzle with thickness set to 0.05mm and less, boron is locally diffused even of the base metal 10 is dipped in mixed solution since the thickness of its coat is excessively thin, and erosion resistance is not improved. On the other hand, when the thickness is set to 0.20mm or more, the thickness of its coat is excessively thick, and boron is diffused to the base metal 10 taking a long time. Diffusion of boron during bathing exerts an influence on a porosity of an alumina coat of the base metal, and in the case where the porosity is 5% and less, formation of Fe2 B in an intermediate layer 13 is obstructed, and the strength of the whole base metal 10 is insufficient in the case where the porosity is 15% or more.  On the other hand, when the base metal 10 is dipped into the mixed solution, the intermediate layer 13 is formed in two layers of FeB and Fe2 B necessarily, and however, the FeB is a brittle layer originally. The coat thickness of a boride layer 11 for covering the base metal 10 of the turbine nozzle is set to 60μm to 100μm.

Filed: 1992-11-17
Abstract: PURPOSE:To enable the detection of a small flaw signal by correcting a differentiation signal based on waviness in the direction of the width of a strip detected to remove the effect of the waviness. CONSTITUTION:A differentiation waveform flatness detector 50 samples a differentiation signal of a differentiator 34 obtained by differentiating reflected light on the surface of a strip 10 together with a scan position data of a scan position transmitter 56 to detect the flatness (waviness) of an output waveform of a differentiator 34. A differentiation waveform is sampled every time the strip 10 moves by a fixed value and this operation is repeated at a frequency set to output a flatness signal determined from a mean of the differentiation waveform. A flatness corrector 52 performs an addition of the flatness signal to or a subtraction thereof from a differentiation signal in the actual detection of flaws making a positioning based on a signal 56 to correct the flatness of the differentiation waveform. Then, a noise level of a correction differentiation signal is measured with a noise level measuring device 54 to set 36 a threshold. A comparator 38 compares the differentiation signal corrected in the flatness with the set threshold to generate a detect signal when the correction differentiation signal exceeds the threshold.

Title: Deodorizing liquid for garbage
Inventor: HIRATA JUNICHIRO
IPC: A61L9/01
Filed: 1992-11-17
Abstract: PURPOSE:To provide a deodorizing liquid for garbage with a remarkably excellent deodorizing effect. CONSTITUTION:The deodorizing liquid contains 10 to 200ml of liquid aldehyde compound, 5 to 50g of 1,2-bromo-2-nitro-1,3-propanediol and 50 to 500ml of centrifugal supernatant of a culture liquid of microbes such as bacillus, stretrococcus, lyzopus, enterobacter or aspergillus containing a deodorizing ingredient. Especially this deodorizing liquid demonstrates an excellent deodorizing effeft upon the odor of fish-based garbage such as originating from triethylamine. A liquid aldehyde compound of the constituent component of the deodorizing liquid displays sterile/deodorizing effects and the 2-bromo-2- nitro-1,3-propanediol displays sterial/antiseptic effects. If garbage becomes rotten to an advanced stage, a larger amount of odor generates. This 2-bromo-2- nitro-1,3-propanediol prevents garbage from becoming rotten and inhibits the generation of an odorous gas component.
