Title: Liquid-level detecting apparatus
Inventor: KUBOTA KOJI
IPC: G01F23/24
Filed: 1989-04-18
Abstract: PURPOSE:To detect a remaining quantity accurately with a few electrodes by providing at least one common electrode and one intrinsic electrode for a plurality of ink containers, applying a retrieving voltage to either of the electrodes, and detecting the change in potential of the intrinsic electrode. CONSTITUTION:Common electrodes l1 and l2 are provided for ink containers 1, 2, 3 and 4 for yellow, magenta, cyanogen and black inks. Intrinsic electrodes e1, e2, e3 and e4 are arranged for the ink containers 1 - 4. A retrieving voltage is applied to the common electrode l1 in response to a detecting-level selecting signal from a CPU 9. Then, the level of each container is compared with a level 1. When the retrieving voltage is applied to the intrinsic electrodes e1 - e4, the level of the container is compared with a level 2. Therefore, the total number of the detecting electrodes becomes the sum of the number of the containers and the number of the common electrodes, and the level can be detected accurately with a very few electrodes.

Abstract: PURPOSE:To prevent oxidation of a metallic briquette in the course of storage extending over a long period of time, and in a holding time in a smelting furnace, by forming a film of a soluble inorganic oxide on the outside circumference of the metallic briquette. CONSTITUTION:Granulated or pulverized reduced iron is press-molded together with a solid carbon substance of small particles by a small quantity of inorganic caking agent such as water-glass as necessary, in order to obtain molten iron by smelting it, by which a briquette is obtained. On the outside circumference of this reduced iron briquette, a film is formed by sticking a granulated body or a pulverized body of an inorganic oxide such as glass which is melted at a lower temperature than the briquette, by use of an inorganic adhesive such as water- glass, or mixing and applying them. When a temperature is elevated in order to smelt this briquette in a smelting furnace, at first, glass of the surface is melted, a molten glass film is formed, and oxidation is prevented until the briquette is smelted. After molten iron has been produced, molten glass floats on the molten iron, the molten iron is intercepted from the open air, and oxidation of the molten iron is prevented.

Title: Cooling absorber for high temperature harmful gas and method thereof
Inventor: WATANABE RYOICHI
IPC: B01D53/77
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To remove corrosive harmful components by using a vertical flue tube end part whose lower part is opened into a wetted wall column for a venturi type restriction pipe and providing a cooling liquid absorbent spray nozzle adjacent to the inlet of the throat part of the restriction pipe to effectively cool the high temperature waste gas to the steam saturation temperature. SOLUTION: A vertical flue pipe end part 1 is inserted into a wetted wall column 2, and has a taper whose diameter is made small downward above the upper cover part of the wetted wall column 2 to form a venturi type restriction pipe which is opened into the wetted wall column 2 with a flare. A cooling liquid absorbent spray nozzle 3 is fitted to a position adjacent to the inlet of the throat part of the venturi type restriction pipe. By spraying a cooling liquid absorbent to a part in which high temperature waste gas is restricted by the throat part to make it have high velocity, liquid droplets are more atomized. And by strong agitation and mixing, gas-liquid contact efficiency is increased to adiabatically cool the high temperature waste gas to the steam saturation temperature at a stretch. Therefore, corrosive harmful components such as hydrogen chloride contained in the high temperature waste gas is absorbed and removed with high removal efficiency.

Title: Method of damping flow of medium passing through valve and valve applying therefor
Inventor: YUHANI PORON
IPC: F16K5/12
Filed: 1981-06-26
Abstract: A method for attenuating a medium flow passing through a valve provided with a flow passage. Into the valve, a substantially ball-like or ball-segment shaped or conical or cylindrical plug-like closure member has been fitted turnably. The attenuating of the flow has been arranged as taking place in both flow directions mainly in the passage in the closure member or in a bore passing through the closure member. The attenuating effect is increased as the valve is being closed and the attenuating effect is correspondingly reduced as the closure member is being turned towards the open position. In the passage in the closure member or in the bore passing through the closure member, the length of the path of flow of the pressure medium is increased and the direction of the flow of the pressure medium is alternated. The more the valve is being closed, the longer becomes the path of flow of the pressure medium in the bore or passage in the closure member and, correspondingly, the higher becomes the number or changes in direction of the pressure medium flow within the range of the passage or bore in the closure member.
