Title: Fluidized layer boiler and operation method thereof
Inventor: HOKARI NOBUYUKI
IPC: F23C10/18
Filed: 1995-01-13
Abstract: PURPOSE: To stabilize a conveying quantity by homogenizing a particle layer as a whole in storage equipment with the agitation of fluid medium particles in the storage equipment to keep the shape of the particles to be conveyed constant with the passage of time. CONSTITUTION: A fluid medium agitation blade 26 is set in a fluid medium tank 14 and rotated by a motor 27 to homogenize a fluid medium 15 in the tank 14. The agitating blade 26 may be always rotated constantly or may be rotated only for a specified time during the supply of the fluid medium 15. As a result, a particle size distribution of the particles to be sent to a fluid medium injection conveying pipe 16 to a combustor 1 from the fluid medium tank 14 is always constant. This enables the keeping of a relationship between the flow rate and inflow time of air 17 for conveying and the conveying quantity of the particles constant thereby stabilizing the conveying quantity of the fluid medium 15.

Abstract: PURPOSE:To achieve the miniaturization of an apparatus and the enhancement of measuring sensitivity, by a method wherein a structure capable of holding a liquid is provided between a living body catalyst electrode and an opposed electrode and a small amount of a buffer solution is held between both electrodes in measuring while a specimen is added to said buffer solution. CONSTITUTION:For example, each of both electrodes 12, 13 is formed of a reticulated body or a plate body having a large number of holes and mutually confronted at a short interval so as to be capable of holding a small amount of a liquid therebetween by utilizing surface tension. In measuring, both electrodes are at first immersed in a buffer solution and drawn up therefrom and a small amount of the buffer solution is held between both electrodes by surface tension. In the next step, potential difference is preliminarily generated between both electrodes by using a potentiostat and a predetermined amount of a specimen is dripped to the living body catalyst electrode 12. When the current flowing between both electrodes 12, 13 is measured, the concn. of the specimen is known. As mentioned above, because the buffer solution is used in a small amount, measuring sensitivity is good and constitution is simple and can be miniaturized.

Title: Position detector
Inventor: HAYAKAWA TOSHIFUMI
IPC: G01B7/00
Filed: 1985-01-17
Abstract: PURPOSE:To directly detect the position of a moving body stably with high accuracy, by providing a memory, adding means, etc., which output a correcting value in accordance with the deviation between the detected position and the actual position of the moving body. CONSTITUTION:When the moving body 1 is inserted into or pulled out from the electromagnetic space between the primary winding 2 and secondary winding 5, the AC voltage induced from the winding 5 varies. The AC voltage is converted into a DC voltage by means of an AC/DC converter 6 and becomes a signal. An A/D converter 7 digitizes the signal into an address signal and designates a storing address in a memory 8. When the address is designated, the memory 8 outputs a correcting value stored in advance in the form of a digital signal. The correcting value in the form of a digital signal is converted into a DC voltage by means of a D/A converter 9 and the output of the converter 6 is added by an adder 10. Therefore, the position signal of the moving body 1 obtained from the adder 10 becomes a signal which has such a characteristic that the strength of the signal linearly changes in accordance with the position of the moving body 1 and is close to an ideal curve, and an indicator 11 indicates the correct position of the body 1.

Title: Temperature control of iron skin in blast furnace
Inventor: TATEOKA MASAKI
IPC: F27D1/12
Filed: 1978-01-20
Abstract: PURPOSE:Blast furnace iron skin is separated from outer skin to provide a space area therebetween. The temperature is lowered by moving the air in the space, which results in the iron skin free of stress-corrosion-crack and heat cracking. CONSTITUTION:The blast furnace iron skin 8 is cooled by the gas in the duct 4 which is forcedly or naturally moved upward from the iron skin lower portion. The thermometer 7 is mounted at a location where temperature is frequently regulated. The regulation is such that the gas is caused to flow at a temperature of over 250 deg.C, and the draft openings 6,6' are closed below 150 deg.C so as to maintain the temperature of the iron skin 150 to 250 deg.C. Opening and closing of the valves 10, 10' can be manually or automatically operated. This process provides means to prevent the iron skin from the generation of NOxcracking.
