Abstract: PURPOSE:To readily obtain an expanded ceramic plate in which mesh stripe is horizontally arranged by putting the mesh stripe between inflammable sheets and laying the mesh-containing sheet between the lower layer and upper layer of a raw material granulate in production of reinforcing expanded ceramic plate. CONSTITUTION:In a method for producing the objective expanded ceramic plate, 100 pts.wt. silicic acid-containing substance other than blast furnace slag (e.g. shirasu) and 0-70 pts.wt. blast furnace slag are used as main components.

Particle size of the granulate is preferably about 0.1-5 mm. Then the lower part consisting of the granulated material of raw material is formed in a frame mold so as to horizontally keep upper face thereof and mesh stripe (e.g. stainless steel having 2-10mm mesh size and 0.3-1mm coarseness of net yarn) is put thereon in a state sandwiched between inflammable sheets (e.g. paper) and further, the granulated material is packed from above to form the upper layer.

Title: Pressure resistant self-standing container
Inventor: SHIBUYA TAKEYOSHI
IPC: B65D1/02
Filed: 1992-12-17
Abstract: PURPOSE:To provide a pressure-resistant and self-standing container which is molded as a unit without use of a base cup and shows an excellent self- standing stability even when an inner pressure acts therein, by providing at least one of recessed part at the outer side of grounding positions in respective legs. CONSTITUTION:Five legs 10 are arranged every same interval in the periphery at the bottom of a container 1. Respective legs 10 are extended smoothly from the shell wall of the container 1 and the container is provided with the grounding faces 11 which contact the supporting face of container at the lower end. One longitudinally long elliptical recession 12 is formed in the radial direction in every leg. Since the recessions 12 are formed at the outside of the grounding faces 11, it brings a great resistance against expansion. Accordingly, the lower end of the legs 10 does not extend outward and hence, it prevents the legs from uneven deformation. The recession 12 is not necessarily required to be longitudinally elliptical but it may be laterally elliptical. And the shape of recession 12 is not necessarily required to be ellipptical but a circular, triangular and square shapes are also serviceable.

Title: Method and apparatus for blowing reactive agent in boiler facility
Inventor: KEGA HISASHI
IPC: F23C99/00
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To enhance reaction efficiency by blowing a reactive agent into a furnace while crushing finely and causing the reactive agent to react on combustion exhaust gas thereby preventing aggregation of the particles of reactive agent, e.g. desulfurization agent or active carbon, and ensuring pore area of the reactive agent. SOLUTION: Under a state where fuel, e.g. pulverized coal, is fed from a burner 3 into the furnace 2 of a boiler body 1 and burnt, a desulfurization agent stored in a bin 4 is fed by means or a feeder 5 and thrown into a pulverizer 7. Pulverized desulfurization agent is blown into the furnace 2 of the boiler body 1 by means of air being fed from a fan 6 and caused to react on combustion gas thus desulfurizing the combustion gas. Since the desulfurization agent is not stored temporarily after being pulverized by the pulverizer 7 but blown directly into the furnace 2 of the boiler body 1, particles of the pulverixed desulfurization agent dos not aggregate substantially. Consequently, pore area is ensured and a sufficient desulfurization efficiency can be attained.

Title: Internal combustion engine
Inventor: ITO TAKEKAZU
IPC: F01N3/24
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To simultaneously prevent exhaust of soot and NOx, and prevent increase of a soot generation amount due to inapropriate low temperature combustion when the exhaust gas is hardly exhausted from a combustion chamber to an engine exhaust passage. SOLUTION: Exhaust of soot and NOx can be simultaneously prevented by performing low temperature combustion which brings about an EGR gas amount causing a peak of a soot generation amount less than an EGR gas amount to be supplied to a combustion chamber 5, and hardly causes generation of soot. The low temperature combustion is prohibited when it is determined that the exhaust gas is hardly exhausted from the combustion chamber 5 to an exhaust manifold 22, according to an output value of a pressure sensor 53 which senses the pressure in the exhaust manifold 22. As a result, it is possible to prevent increase of a soot generation amount which may be caused by inapropriate low temperature combustion.
