Title: Piping regeneration and repairing work method
Inventor: KUWANO HIROYUKI
IPC: F16L55/18
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To easily correct flat portions of a flexible pipe adopted to a gas piping, which may be caused by external force, etc., along the shape of pigs by making the multiple pigs pass through the flat portions of the flexible pipe. SOLUTION: A regeneration means 9 used for restoring a flexible pipe to be an original shape is composed of a wire 10 having a connection part on one end in the longitudinal direction, and multiple pigs 10 having, for instance, three different diameters arranged on the wire. The pig 11 has a warhead form with a conical head, in which a maximum outer diameter corresponds to an aperture of the flexible pipe and a leading end is reduced in its diameter in the pulling direction. The wire 10 is connected to a steel belt as a traction means and tracted by a small-sized winch 17. During traction, the multiple pigs 11 having the diameter enlarged in order interfere the flexible pipe to widen its flat portions. Its inner diameter is restored substantially to an original state.

Title: Premixing face type flame burner
Inventor: KUBOTA NORIKAZU
IPC: F23D14/70
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To make it difficult for a lifting phenomenon of a flame to occur and hence improve heating efficiency and reduce NOx for ensurance further air excess combustion by dividing a mixed gas chamber into inner and outer two chambers at positions corresponding to an outer peripheral part of a combustion plate and an inner peripheral part of the same. SOLUTION: An original mixing surface shaped flame type burner 100 is adapted such that the interior of a mixed gas chamber 2 including a combustion plate 1 disposed on a front surface is divided with a partition wall 3 into an inside mixed gas chamber and an outer peripheral side mixed gas chamber. Herein, the width of the outer peripheral side mixed gas chamber is less than 10mm even when it is narrowed and less than 50mm even when the same is widened.  The mixed gas supplied to the upstream side 5A of the outer peripheral side mixed gas chamber and flowing into the downstream side 5B is more reduced in its amount than the mixed gas supplied to the upstream side 4A of the inside mixed gas chamber and flowing to the downstream side 4B, and further a ratio of fuel gas is high, so that a flame formed on the surface of the combustion plate 1 is suppressed smaller along the peripheral part in the amount of lifting, and hence even when air excess combustion is performed at the central part of the combustion, the flame is difficult to undergo a lift.

Title: Method and device for analyzing particulate material
Inventor: MATSUI TETSUYA
IPC: G01N29/00
Filed: 1989-12-13
Abstract: PURPOSE:To improve measurement accuracy by detecting the light emitting position of plasma generated by the breakage of the particulate material with exciting light irradiation and correcting a measured value of the plasma light emitting intensity by using exciting light output density at the position. CONSTITUTION:Exciting light 21 is guided in a sample cell 3 to form a beam waist 23 in the cell 23. A sample 24 is made flow in the cell 3. When particles in the sample 24 are irradiated with the light 21 at the position of the waist 23, the particles are broken and the plasma 25 is generated to radiate plasma light 22. The light 22 is converged on a light emission position detector 11 to detect the position and intensity of the light. Its detection signal is sent to a signal processor 6 and sent to a data processor 7 as data by shots of the pulse irradiation 1 of the light 21. The processor 7 calculates particle size from a correlation expression between the light emission intensity and the particle size of the particulate material by using both data on the intensity and position of the light emission 22 obtained under normal conditions. Accurate particle size after the influence of the plasma generation position is removed is measured by this method.

Title: Premixing burner
Inventor: HANSU PEETAA KUNEPUFUERU
IPC: F23D17/00
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To optimize requisite conditions of flow by arranging a perforated plate attached to an injector mechanism to extend parallel with an inflow plane into a supply path while an injector nozzle is provided in such a manner that the inflow angle thereof varies continuously in the longitudinal direction of a premixing burner with respect to the axis of the burner. SOLUTION: In the drawing describing a premixing burner 100 by the direction of flow, perforated plates 23 and 24 extend parallel with each other to an injector mechanism provided for an inflow plane 30 into a supply path. The inflow plane itself is also parallel with the axis of a premixing burner 100 in the overall length thereof. Moreover, the inflow angle of injector nozzles 23a and 24a to the axis of the premixing burner 100 varies with the direction of flow. The inflow angle changes sequentially starting from an acute angle within an area of a head stage of the premixing burner 100 almost to the right angle to the axis of the burner within an area of an outlet of the premixing burner. This change affects positional stability of a reverse-flow zone accordingly.
