Title: Method for coating bottom of converter fitted with bottom blowing nozzle
Inventor: NITTA MASAKI
IPC: C21C5/44
Filed: 1986-12-17
Abstract: PURPOSE:To easily form a coating layer of a required thickness on the bottom of a converter fitted with a bottom blowing nozzle without causing blocking trouble by coating the bottom of the converter with molten or semisolid slag and blowing an inert gas from the nozzle at a proper blowing rate during the coating. CONSTITUTION:After steel is tapped from a converter fitted with a bottom blowing nozzle, calcium oxide, light dolomite or the like is added to converter slag to obtain molten or semisolid slag. The converter is then titled to coat the bottom of the empty converter with the slag. In the coating stage, an inert gas is successively blown from the bottom blowing nozzle at >=0.025Nm<3>/ton.min blowing rate per one hole of the nozzle. Thus, a relatively thick protective coating layer of slag can be formed without blocking up vent holes in a mushroom and the service life of the bottom of the converter can be prolonged.

Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To measure the carbonate concentration in the slurry represented by the absorbing solution of desulfurizing equipment by preventing the settling and separation of limestone particles in the slurry and fixing the temperature of the slurry or by taking such a case into consideration that the dissolved CO2 concentration in the slurry reaches the saturated solubility or higher. SOLUTION: Carbonate-containing slurry A is supplied to a tank 18 provided with an overflow pipe 20 and an agitator 19 from a slurry supplying pipe the front end of which is maintained lower than the pipe 20 and the settling and separation of limestone particles in the slurry are prevented by sufficiently agitating the slurry A in the tank 18. Then the dissolved CO2 concentration in the slurry A is measured in a dissolved-CO2 concentration measuring tank 15 by controlling the temperature of the slurry A so that the fluctuating range of the temperature may be reduced to <=3 deg.C.  At the time of measuring the CaCO3 concentration in the slurry A, the pH value of the slurry A is made to be maintained easily and the CaCO3 concentration in the slurry A is made to be found accurately by calculating the carbonate concentration in the slurry A before the slurry A is diluted with water D by mixing the water D in the slurry A to a prescribed flow rate so that the dissolved CO2 concentration may become lower than the saturated solubility before adding an acid C.

IPC: B05C9/14
Filed: 1987-11-30
Abstract: PURPOSE:To form a bubble-free coating film by applying an airless spray coating of a coating agent under normal pressure to the inner surface of a hollow rotating body-like article while rotating the same and, immediately thereafter, by heating the article from the inside at reduced pressure. CONSTITUTION:A hollow rotating body-like article C placed in a pressure resisting container 1 is turned with both the ends of the article C held between two spindles 7 and 8. An airless spray coating of a coating agent is applied under normal pressure from a gun nozzle 5 to the inner surface of the article C while rotating the same. Immediately thereafter, a solenoid type air valve 12 on a vacuum pipe 11 in communication with the inside of the spindle 8 is opened, thereby reducing the inner pressure of the article C to a degree of vacuum between 760Torr and 0.2Torr. At the same time, a hot air HA is sent into the pressure resisting container 1, whereby the article C is heated from the outside at the required temperatures and the coating layer is subjected to a dry aging from the bottom to the surface. As a result, a uniformly thick coating film free from air bubbles can be formed in a short time.

Abstract: PURPOSE: To make it possible to correspond to each required condition by a simple structure without being influenced by temperature, by disposing a rubber spring element of a shock absorber for elastically buffering a forward tilting motion between a core piece and a tube piece, and by enabling a member composed of a rubbery elastic material to make a restricted relative rotation between the core piece and the tube piece. CONSTITUTION: This shock absorber 28 comprises a torsion rubber spring element 30', the core piece 32' of which is rigidly joined with a lower shell 14 and is further provided with a tube piece 36 capable of twisting relative to the core piece 32', around which a pull band 40 is fixed, whereby a bolt 42 gives action force to a rear shaft 18 through a nut 44. Also, the shock absorber 28 buffers a forward tilting motion on one hand, and makes a shaft 16 elastically return to a given position or a starting position on the other hand. An article 50 constituted from a rubber elastic material allows 32' and 36 to rotate relatively and restrictedly, thereby giving the rubber spring element 30' an action of a torsion bar.  In this case, the rubber body performs a torsional rotary motion, while the spring characteristic thereof is hardly influenced by the ambient temperature within a broad limitation.

Abstract: PROBLEM TO BE SOLVED: To prevent the entering of external light beams, to easily observe an image, to reduce eye strain and to prevent the increase in the size by tilting both side surfaces of the eyepiece section, which is linked to the both side surfaces of a mounting section, to the inner side. SOLUTION: The eyecup consists of a front side mounting section 21 and a back side eyepiece section 22 which contacts with a face and the sections 21 and 22 are integrally formed. Left and right sides of side surface walls 25 are constituted of a first surface section 25a of the section 21 side and a second surface section 25b of the section 22 side running in a row. Left and right sides of the section 25a are formed so that they become approximately parallel. On the other hand, the section 25b is tilted to the inner side so that the section 25b is made closer toward the end tip section of the section 22. Thus, the back tip section of the section 25 matches with the curvature of the face around an eye, the section 22 is tightly contacted to the face and no external light beams enter into the eyecup through the section 22 and the image is easily observed.  Note that the eyecup is freely attachable and detachable and the increase in the size of the optical mirror is prevented.
