  • Publication number: 20240145926
    Abstract: A dielectric block includes a bottom surface that includes a conductive ground member including an antenna ground surface inclined with respect to the bottom surface. A feed element is disposed at a distance from the antenna ground surface, and constitutes a patch antenna together with the antenna ground surface. A feed line is connected to a feed point of the feed element, and a dielectric member that supports the feed element with respect to the ground member. The ground member is exposed to the bottom surface, on both a lower side and a higher side of a contour line passing through an intersection point of a perpendicular line from the feed point to a virtual plane including the bottom surface and a plane including the antenna ground surface, using the bottom surface as a height reference.

  • Publication number: 20230135918
    Abstract: A manufacturing system including a container manufacturing line for manufacturing a container, and a filling line for filling the container with a filler is provided. The container manufacturing line is coupled to the filling line, and the container manufactured in the container manufacturing line is supplied to the filling line. The container manufacturing line may include a first speed control unit for controlling a manufacturing line speed depending on a filling line speed of the filling line. The first speed control unit may change the manufacturing line speed of the container manufacturing line depending on a change in a number of containers in a predetermined process of the filling line.

  • Patent number: 6926516
    Abstract: The present invention relates to a combustion method and a burner for forming a flame temperature having a flat temperature distribution which is the same as that in a case of a long furnace length even if a furnace length is short, and performs complete combustion. Further, a regenerative burner technique can be applied even if a furnace length is short. Combustion air whose quantity is less than the theoretical air quantity or not less than the theoretical air quantity is injected into a furnace so as to form a jet flow cross section having a larger specific surface area than that in a case of supplying the same quantity of combustion air from a circular throat, and fuel is injected toward this air jet flow to cause the fuel to be rapidly mixed with the air jet flow with strong turbulences before losing the velocity energy of the fuel. More preferably, an air throat 13 has a flat rectangular opening 13a.

  • Patent number: 6880619
    Abstract: A heat treatment equipment having a heating chamber having a plurality of regenerative combustors provided with direct-fired burner having a built-in porous regenerator, for applying a heat treatment to an object in the heating chamber, wherein the substantial average surface pore diameter is not uniform for porous regenerators in a plurality of direct-fired burners or a plurality of regenerative combustors. By making contrivances in the shape of porous regenerators of the direct-fired burners or the regenerative heat exchangers arranged in an area where substances causing choking tend to easily adhere to make it difficult for such substances to adhere or prevent choking phenomenon from becoming apparent.

  • Patent number: 6547555
    Abstract: In a regenerator made of materials each comprising alumina as a main ingredient, and used for the regenerative combustion burner which is fired with alternately and repeatedly operations of heat storage by the passage of high-temperature flue gas in a fixed time and heating of combustion air by passage of the combustion air in a next fixed time, under the condition that the flue gas includes metal dust; the alumina purities in the materials for the regenerator are lowered in the order, the high-temperature, medium-temperature and low-temperature parts of the regenerator.

  • Patent number: 5441403
    Abstract: A method of low-NOx combustion and a burner device for effecting the same, in which a primary fuel is injected in a direction from tile periphery of stream of a combustion air towards that same combustion air, effecting a first combustion, so as to create a generally cylindrical primary flame covering the combustion air, whereby a secondary fuel injected towards the combustion air is shielded or intercepted by such primary flame from the combustion air, while causing NOx in tile primary flame to be reduced by the secondary fuel, after which, a second combustion is effected by bringing the secondary fuel to contact with a portion of the combustion air penetrating through the primary flame, at a downstream side. This arrangement permits more positive decrease of NOx density in an exhaust gas.
