Title: Pulverized waterrsoluble crystalline substance* its manufacture and water suspension containing said substance
Inventor: JIEEMUSU AREKISANDAA ENEBAA
IPC: C06B47/14
Filed: 1980-09-18
Abstract: Water-soluble crystalline material which has been comminuted in a saturated aqueous solution of the material in the presence of a water-soluble crystal-growth inhibitor having a hydrophobic portion and a hydrophilic portion in its molecular structure is mixed with a deflocculant which inhibits the interaction of the hydrophobic molecular portions whenever the comminuted solid is suspended in water. The viscosity of aqueous suspensions of comminuted solid is thereby stabilised.The invention is especially beneficial in the preparation of aqueous suspensions of finely comminuted ammonium nitrate for use in slurry blasting explosives.With crystal-growth inhibitors such as water-soluble polysaccharide derivatives, long chain aliphatic amines, polyacrylic acids, sulphonated nuclear aromatic compounds, sulphonated dyes or sulphonated polymers the preferred deflocculant, which should be different from the crystalgrowth inhibitor, may include water-soluble polysaccharide derivatives, polyacrylic acid, polyvinyl pyrrolidone, sodium lignosulphonate and/or a salt of a condensate of naphthalene sulphonic acid with formaldehyde.

Title: Formation of oblique hole
Inventor: WATANABE HIDEKI
IPC: B23B35/00
Filed: 1985-06-13
Abstract: PURPOSE:To enable an efficient machining fabrication and to aim it preventing a cutter tool, etc. from being broken, by providing such an arrangement that an aluminum alloy plate having a low cutting resistance but a strength capable of guiding a cutter tool, is bonded to a planar plate during heat-treatment so that an oblique hole and an accompanying hole are formed being guided by the aluminum alloy plate, and the aluminum alloy plate is then removed after heat-treatment. CONSTITUTION:An aluminum alloy patch plate 4 is bonded to a stainless steel planar plate 1 to be fabricated with the use of an adhesive material 4. A milling process is very suitable for fabricating an oblique hole 2, and the therefore, the fabrication is initiated at the surface of the patch plate 4 by means of an end mill 3. Due to the use of aluminum materials for the patch plate 4, the end mill 3 may make the fabrication precisely without any deflection. Accordingly, there may be prevented any shift of the tool caused by a cutting resistance due to the already formed hole in the patch plate 4 which serves as a guide for the tool, and therefore, the oblique hole may be formed with a high degree of accuracy. Then, after completion of the fabrication, the planar plate is subjected to an annealing process in which a heat having a temperature of 400-450 deg.C is applied, and therefore, the adhesive material 5 deteriorates so that the patch plate 4 may be easily removed from the planar plate 1. With this method, it is possible to avoid positional errors, breakage of a cutter tool, etc.

Title: Manufacture of anisotropic permanent magnet by hot-rolling
Inventor: YAMAGAMI TOSHIAKI
IPC: C21D8/12
Filed: 1990-05-18
Abstract: PURPOSE:To improve productivity and obtain a high performance rare earth - transition metal (R-TM-B) anisotropic permanent magnet at low cost by performing hot-rolling while applying rearward tension or rearward tension and forward tension at the same time to a rolling material. CONSTITUTION:Defining that the roll center angle between the neutral position and the exit of a roll 1 is phi and that the thickness in rolling direction of the metallic sheath 2 and the metallic plate at the neutral point is Sd, it is hot-rolled while applying such rearward tension or rearward tension and forward tension at the same time that the value of Sd/sinphi may be 800 or more during hot- rolling. Hereupon, since the anisotropic permanent magnet made here is oriented and made anisotropic, the hot-rolling process is a very important process, and it needs to be deformed more uniformly. Hereby, productivity improves sharply, and a high performance, stable and cheap R-TM-B permanent magnet can be obtained.

Title: Quantitative analysis by sample surface scan type analyzer
Inventor: HIRAI TERUJI
IPC: H01J37/22
Filed: 1986-06-03
Abstract: PURPOSE:To enable observation of the shape and a distribution state of dispersed particles and quantitative analysis thereof with an analyzer of such a type as scanning the surface of a sample by a charged particle beam, by calculating the proportion of area of a radiation range of characteristic X-ray with respect to the surface of the sample according to border lines drawn inward by a distance determined by the sample and an electron beam accelerating voltage. CONSTITUTION:First, an X rays spectroscope C is set to match the wavelength of characteristic X-ray of element to be determined. A sample S is driven to reciprocate while an electron beam B is converging on the surface thereof to scan and an output data of an X rays detector Dx is stored into a memory M. Here, when the expanse of the radiation range of characteristic X-ray is represented by (d) with respect to the sample S, the region where the desired element exists is in a realm surrounded by the chain line drawn inward by (d) in each range A. The true area for the intended phase is determined by measuring the area of the region inward by a determined portion and thus, the determination of element is done according to the proportion of the area thus obtained thereby enabling accurate quantitative analysis.

IPC: C02F11/00
Filed: 1977-10-28
Abstract: PURPOSE: To accomplish the regulation of sludge concentration together with the removal of big refuges such as dregs and of sands.  
     CONSTITUTION: With the actuation of a pump P 1 , a sludge is introduced into a screen device 8 from the outlet port of a sludge concentration tank 5 to remove big refuges such as dregs. The sludge thus treated passes through a concentration measuring device 10 to a sludge storage tank 9 for storage. A valve provided on a pipe 12, one end of which is communicated to a diluting water source, is in linkage with the device 10. When the concentration of the sludge is higher than the set value, the valve 11 is properly opened to add diluting water to the sludge in the tank 9, thus providing a proper sludge concentration. Whenever the concentration is proper, the sludge is introduced into a liquid cyclone 13 through an inlet port 13a by a pump P 2 . In the cylone, sands are removed from the sludge and discharged out from the lower outlet port 13c. The sludge thus free of sand is introduced into a digestion tank 14 through the upper outlet port 13b to decompose organic matters therein, and then proceeded to a dehydration apparatus 6 to be dehydrated. Consequetly, the sludge thus deydrated is burned in an incinerator 7.

Abstract: PURPOSE:To protect a filter against damages due to melting by a method wherein a thermosensor is provided on the downstream side of the filter in an exhaust gas passage and when the rising gradient of the temperature detected by the thermosensor is higher than a predetermined value, the operation of a clogging removing means is stopped. CONSTITUTION:Exhaust gases from the engine 1 reaches the filter 4 via an exhaust gas passage 3 and when the gases pass through the filter 4, carbon particles and the like in the gases are collected and removed. In case where the filter 4 is clogged, a clogging detector 6 detects the clogging of the filter from the lowering of the resistance value between electrodes 5a and 5b. Thus a fuel pump 13 and an air pump 14 are driven by the output of the clogging detector 6 through a control circuit 16 and the burner 7 is operated by turning an ignition switch 9 ON to thereby remove the clogging of the filter. Further, the rate of elevation of the exhaust gas temperature is detected from the output of the thermosensor 15 during the clogging removing operation and the detected rate is compared to a set value. Then, when the exhaust gas temperature is found higher than the set value, the operation of the burner 7 is stopped.
