摘要： PROBLEM TO BE SOLVED: To provide a leveler for icehouse in which articles to be stored in a storage compartment adjacent to a snow and ice compartment can be cold insulated efficiently by making uniform the height of snow piled in the snow and ice compartment. SOLUTION: When the surface of snow and ice made by an ice making machine 2 and piled in a snow and ice compartment 1 is positioned higher than a conveyor chain 11, a motor is turned on and the sprocket of a drive pulley truck 5 rotates to move a scraper along with the conveyor chain 11 thus shifting the snow and ice in the direction of the drive pulley truck 5. Consequently, the height of piled snow and ice is averaged.

摘要： PURPOSE:To adequately control the tension of a coil and to lessen generation of flaws on this coil by adjusting a regulator by an air pressure and controlling the torque of an air brake. CONSTITUTION:The coiling diameters at a payoff reel 1 are successively measured and the momentarily changing measured values are exchanged to electric currents which are inputted to an arithmetic unit. The rigidity of the coil is determined from these input values and the width and thickness, etc., of the coil 2 previously inputted to the unit. The adequate set pressures of the air brake 6 are successively calculated and the signals based on the set values are outputted to a regulator 9 to regulate the braking of the air brake 6, by which the reverse tension of the un-coiled coil 2 is so controlled as to be kept adequate at all times. As a result, the torque of the air brake is controlled and, therefore, the tension of the coil 2 between the payoff reel 1 and a processor 3 is adequately controlled and the generation of the flaws on the coil is lessened.

摘要： PURPOSE:To perform a low air ratio combustion and a complete combustion at the time of a low heating value by disposing a central body at the center of a cylinder in a secondary combustion area. CONSTITUTION:A secondary air blown out of the inner wall of a burner is rectified along the inclined surface of a central body 7 of a secondary combustion area 8 above a burner pot 1 and elevated. Since the flow stream line of a fluid can be made constant because of the presence of the central body 7, the flow of fluid the same as that at the time of the maximum heating value can be obtained even at the time of a small heating value in which a flow rate is low. Thus, the mixed air of a combustion air and a fuel steam can be completely mixed. Further, the central body 7 is red-heated by flame, so that the flame holding and combustion reaction of this central body 7 are effectively urged upon combustion at a low heating value where the temperature of flame is especially lowered and an incomplete combustion is liable to arise. Thus, a low air ratio combustion and complete combustion at a turn-down ratio can be effected.

摘要： PROBLEM TO BE SOLVED: To provide an automatic liquid penetrant inspection method of a steel plate capable of preventing liquid drop of wash water or penetrant, heightening efficiency of a drying process, and preventing clogging of a developer nozzle.
SOLUTION: A pipe 14 close to a nozzle, deformed spirally in the vertical direction is used as a washing nozzle 6 for automatic liquid penetrant inspection of the steel plate, and droplets on the nozzle tip are blown off by air blow from an air pipe 17 when washing is finished, to thereby prevent drop from the washing nozzle 6. In order to prevent drop of residual liquid from a penetrant nozzle, air blow inside the nozzle is performed at the waiting position after application of the penetrant. In order to prevent clogging of the penetrant nozzle, water replacement inside the nozzle is performed at the waiting position after application of the developer.

摘要： PURPOSE: To realize a low-NOX combustion device applicable on a small-size combustion engine. CONSTITUTION: In a two-stage combustion device, in which combustion air or fuel is supplied by dividing it into primary combustion and secondary combustion to effect combustion, cooling pipes 15, 16 are arranged in respective primary combustion chamber 8 and a secondary combustion chamber 12 while combustion gas is cooled in two steps of the primary combustion chamber 8 and the secondary combustion chamber 12. Accordingly, the combustion gas is cooled not quickly in one step but by some degree in a primary combustion area, and secondarily cooled while securing the temperature of gas and advancing the reaction of CO→CO2 in a secondary combustion area. According to this method, the effect of reducing a combustion gas temperature due to cooling is added to the two-stage combustion while restricting the generation of CO whereby the generation of NOX can be restricted in a very low level.

摘要： PURPOSE: To prevent deformation, run-out and crack or the like generated by thermal effects by consisting of slag resistant bricks and insulating bricks with two layers on a steel-made bottom board as a level block. CONSTITUTION: A level block 2 is installed on the upper part of a pallet while a slag case 3 is loaded on the level block 2. A molten slag is injected from a molten steel ladle 4 into the slag case 3, which is made of cast iron, for example. In this case, the level block 2 is made of bricks and the upper part consists of slag resistant bricks 10 while the lower part consists of insulating bricks 11 and both bricks are installed on a steel-made bottom board 12. Therefore, this construction makes it possible to solve various problems about deformations and cracks of a pallet main body generated from thermal effects and provide a high durability brick-made level board by installing high slag resistant bricks on the upper part and solve run-out problems of the level board and extend service life as well.

摘要： PURPOSE: To carry out the low NOx combustion by performing a double stage combustion which comprises a primary combustion to accomplish an even excessively dense fuel combustion by a surface burning and a secondary combustion to accomplish an even fast combustion at a throat part. CONSTITUTION: A liquid fuel is supplied from an oil pipe 1 and vaporized by evaporation with a heater 2 for vaporization to be mixed with primary air 4 to be supplied from a blower 3 and passes through a porous plate 6 as preheated gas 5. The fuel is ignited right above the porous plate with an ignition plug 7 to accomplish a primary combustion. In the primary combustion, burning is made under the shortage of air with an equivalent ratio of 1 or more to check the generation of NOx. When passing through a throat part 9, the mixed gas 5 following the primary combustion in a primary combustion chamber 8 is mixed with secondary air 11 jetting from an air hole 10 to accomplish a secondary combustion. With a higher flow velocity of the combustion gas at the throat part 9, the jetting of secondary combustion air speeds up the mixing of the combustion gas and the combustion air thereby enabling the checking of the generation of NOx with the shortening of retention time in a high temperature secondary combustion zone.
