Title: Method for estimation of quantity of gas generated in coke oven
Inventor: OSHIMA YOSHIHIRO
IPC: C10B21/10
Filed: 1988-10-11
Abstract: PURPOSE:To enable the supply-demand balance of C gas and an action in the operation of a gas purification section to be properly taken by summarizing the approximate expressions for gas generation patterns into equations for three steps and making a correction depending upon the oxygen content of coal to estimate the quantity of gas generated. CONSTITUTION:In the operation of a coke oven, the approximate equations for gas generation patterns are summarized into equations for the first step from coal charge to two hours before the termination of the coking period and for the third step from two hours before the termination of the coking period to coke pushing, and a correction depending upon the oxygen content of coal is made to estimate the quantity of gas generated. By this technique, a generated gas quantity estimation almost equal to the actual value can be obtained; therefore, the supply-demand balance of gas in the plant can be accurately predicted, and the action in the operation of a gas purification section, the coke oven combustion control, etc., can be performed properly, so that a stable operation and a cost reduction can be expected.

Title: Vibration absorber for cylindrical body surface machining
Inventor: MURATA KATSUYUKI
IPC: F16F15/04
Filed: 1991-09-06
Abstract: PURPOSE:To absorb vibration effectively without being influenced by the rigidity and inner diameter fluctuation of a workpiece by forming a vibration absorber of a hollow body formed in such a way that its contact part with the cylindrical workpiece is formed of an elastic body and that the part excluding both ends of the hollow body is divided in the direction of a rotation axis. CONSTITUTION:A vibration absorber 1 is formed of a cylindrical hollow body formed of an elastic body in such a way as to be insertable into a cylindrical workpiece formed of conductive material such as aluminum so as to be the base body of a sensitized drum, for instance. An outer cylinder part is provided with slits 2 formed equally on the surface of the hollow body. Trimming through holes 3 are opened at both end parts of each slit 2 so as to prevent the slit from being enlarged. The longer the length of the slit 2 in relation to the whole length of the vibration absorber 1 within a range of not being damaged, the better. The vibration absorber 1 itself is thereby expanded by centrifugal force so as to come in close contact with the workpiece, and the close contact part is formed of the elastic body, so that vibration isolating effect is prevented from being influenced by the inner diameter accuracy of the workpiece.

Title: Rail gun of nucleus fusion pellet incidence device
Inventor: MATSUDA RYUICHI
IPC: F41B6/00
Filed: 1991-10-02
Abstract: PURPOSE:To enable a rail to be damaged thermally. CONSTITUTION:In a rail gun of a nucleus fusion pellet incidence device, a switch of a power supply circuit 1 is turned on, a large amount of current flows to a plasma armature 2, a flying object 4 is slid at a high speed according to a Rorentz force which is generated at that time, and then it is discharged from discharge hole 6 between rails 3, 3 while the flying object 4 is installed within the discharge hole 6 between mutually parallel rails 3, 3 so that it can be slid. Resistance of plasma is reduced with a gas with a low ionization voltage as the plasma armature 2 and temperature increase as Joule heat is suppressed, thus enabling temperature of plasma to be reduced. Also, since a cation collision due to voltage drop on a surface of the cathode side rail 3 causes the cathode side rail 3 to be damaged, the cathode side rail 3 is constituted by a material with a low work function for enabling thermions to be emitted from the cathode surface easily, thus enabling thermal damage of the rail 3 to be reduced.

Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To reduce cutting resistance optionally, by forming the shape of a cutting blade as a polygonal frustum, and by using a plurality of edges of the cutting blade successively. SOLUTION: An angular billet 1 lengthened by welding end parts together is installed so as to pass through a space encircled by a first-step cutting blade 11a-a fourth-step cutting blade 11d. A cutting blade moving mechanism of a deflashing device 10 is operated, and the cutting blade ridges of the first-step cutting blade 11a-the fourth-step cutting blade 11d are set so as to have optional distances from the surface of the angular billet 1. And then, a weld flash 2 and the first-step cutting blade 11a-the fourth-step cutting blade 11d are relatively moved in the longitudinal direction of the angular billet 1 and meet each other. In this case, the weld flash 2 generated on the angular billet 1 is removed from one end side in the order from the fourth-step cutting blade 11d to the first-step cutting blade 11a.  The cutting blade ridges of the cutting blades 11 is tilted relative to the weld flash 2, and cutting resistance is reduced by cutting by dividing into a plurality of steps of the first-step cutting blade 11a-the fourth- step cutting blade 11d.

Title: Underfloor ventilator
Inventor: OTSUKA MASAO
IPC: F04D29/44
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To reduce the manufacturing cost of an underfloor ventilator in which generation of noises, reduction of supply air and incomplete rotation of a fan can be prevented. SOLUTION: Inner circumferential surface of a fan scrolling casing 7 is constituted of a partial arc concentric to the outer circumferential surface of a centrifugal fan fixed with three blades 16. Inside diameter of an air inlet is made constant in the ventilating direction. Since intricate operations are not required in the design of the fan scrolling casing 7 and the air inlet and the number of parts is decreased, manufacturing cost can be reduced. Since the interval between the inner circumferential surface of the fan scrolling easing 7 and the outer circumferential surface of the centrifugal fan is not extremely limited partially, clogging with foreign matter, e.g. dust, is eliminated.  Furthermore, the centrifugal fan is prevented from abutting against the inner circumferential surface of the fan scrolling casing 7 due to error in the dimensions of the centrifugal fan or the fixing position thereof.
