Title: Solvent for efflorescence and its production
Inventor: KIYONO RYUTARO
IPC: B08B3/08
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To rapidly dissolve and remove efflorescence essentially comprising calcium carbonate produced on the surface of an alkali concrete product such as mortar in the presence of alkali without damaging the base of the product. SOLUTION: This solvent for efflorescence is produced in the following processes. Ammonia gas or a water-soluble alkali soln. containing ammonia is added to water in which ethylenediamine tetraacetic acid is dissolved till the whole soln. changes into alkali. Then another water-soluble alkali soln. which is prepared by dissolving ammonium borate or by dissolving boric acid till the water becomes acid and then introducing ammonia gas or water-soluble alkali soln. containing ammonia into the water till the soln. becomes alkali is added to the mixed soln. above described. Further, cyclodextrin or di- or mono-saccharide sugar is added as an accelerator in order to dissolve calcium carbonate which is the main component of the efflorescence in ammonium borate. Moreover, potassium hydroxide is added in order to dissolve α-quartz which is one component of the efflorescence. The obtd. solvent is applied on an area where efflorescence is produced, and then naturally or forcedly dried.

Title: Hydraulic circuit for upper swing type hydraulic-operated drilling machine
Inventor: TOMINAGA KOKICHI
IPC: E02F9/22
Filed: 1993-02-17
Abstract: PURPOSE:To prevent starting shock by changing over a pilot valve based on a differential pressure detected between running motor pipelines and raising a set pressure of a running motor relief valve during running operation and lowering the set pressure in the early stages of running operation. CONSTITUTION:During operation of a construction machine, no pressure oil is supplied to pipelines 25 and 26 for a running motor 5 where a pilot valve 24 is placed in its neutral position N. Then, a suspension lock valve 20 is placed in a lock position III while no pressure is supplied to a pilot pipeline 23 and no pilot pressure is exerted to variable relief valves 17 and 18, thereby reducing the set pressure. During running time, the pressure oil of either the pipeline 25 or the pipeline 26 for the motor 5 acts so that the valve 24 may be turned in the position of either I or II. Then, the pressure oil is supplied to the pilot pipeline 22 so that the valve 20 may be changed over to a non-lock position IV. Furthermore, the pressure oil is supplied to even the pipeline 23 so that the set pressure of the valves 17 and 18 may be increased. This construction makes it possible to prevent starting shock, and what is more, to simplify the structure and reduce production cost as well.

Title: Inorganic gel and its production
Inventor: JIYOOJI EICHI BIOORU
IPC: C01B33/24
Filed: 1984-03-15
Abstract: The present invention is related to the production of crystal-containing gels and papers, films, fibers, boards, and coatings made therefrom. The process for making the gels comprises three general steps: first, a fully or predominantly crystalline body is formed containing crystals consisting essentially of a lithium and/or sodium water-swelling mica selected from the group of fluorhectorite, hydroxyl hectorite, boron fluorphlogopite, hydroxyl boron phlogopite, and solid solutions among those and between those and other structurally-compatible species selected from the group of talc, fluortalc, polylithionite, fluorpolylithionite, phlogopite and fluorphlogopite; second, that body is contacted with a polar liquid, desirably water, to cause swelling and disintegration of the body accompanied with the formation of a gel; and, third, the solid:liquid ratio of the gel is adjusted to a desired value depending upon the application therefor. Where papers, films, fibers, boards, or coatings are desired, such are prepared from the gel, and, to impart good chemical durability thereto, are thereafter contacted with a source of large cations to effect an ion exchange reaction between the large cations and the Li+ and/or Na+ ions from the interlayer of the crystals, and the products then dried. Glass-ceramic bodies are the preferred starting materials.

Abstract: PURPOSE: To prevent the occurrence of surging by controlling a bypass amount from a bypass hole piercing from scroll to impeller inlet by a method in which a throttling means is controlled by a controller operating through the flow rate in the suction side and the pressure in the discharge side.  
     CONSTITUTION: A bypass flow rate necessary at the flow rate indication regulator 6 is calculated from a pressure difference signal of the flow rate measuring orifice 2 and a discharge pressure signal of the pressure signal generator 4. And, a signal of bypassed amount from the flow rate indication regulator 6 is sent to the regulator 20, the opening area of the bypass hole 17 piercing from the scroll 12 to the impeller 8 inlet, which is necessary for bypass flow rate needed on the inlet side, is calculated, and the moving amount of the piston 15 for obtaining the opening area is sent to the power cylinder 21. Thus, the opening area of the bypass hole 17 can be changed into a necessary size, and also the occurrence of surging can be prevented by returning a part of the pressurized water to the discharge side of the suction side.

Title: Large-scale water pipe network analyzing system
Inventor: NISHIKAWA YASUHIRO
IPC: G06F19/00
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To make an analysis of a pipe network fast by repeatedly operating an equation generating device, an equation solving device, and a pipe network element recalculating device until a solution converges on a certain value. SOLUTION: A data input device 1 inputs pipe network data and an unknown variable extracting device 2 regards only one of two relative variables as an unknown variable to be solved, and finds the other variable by recalculation from the solved unknown variable and excludes it from unknown variables to decrease the number of the unknown variables. The equation generating device 3 generates simultaneous equations regarding the extracted unknown variables. The solving device 4 solves the simultaneous equations, but the simultaneous equations are nonlinear, so repetitive convergence operation is used as a method for solving them. The pipe network element recalculating device 5 calculates the variable excluded from the unknown variables from the solved unknown variables.  An analysis controller 7 performs loop control over the repetitive convergence operation of the nonlinear simultaneous equations and decides the convergence of the calculation and an analysis result output device 6 outputs the variable value of the analytic result.

Abstract: PROBLEM TO BE SOLVED: To reduce the size over the entire part of a device and to assure a sufficient illuminance distribution by shortening the length of a rod lens and shortening the optical path length from a light source section to a liquid crystal display panel. SOLUTION: The rod lens 5 arranged between the light source section and a Fresnel lens is composed of the assemblage of divided rods 5a to 5d divided to a plurality around its optical axis 4.
