Title: Pulverized coal burner
Inventor: KEGA HISASHI
IPC: F23D1/00
Filed: 1985-06-04
Abstract: PURPOSE:To lower lowest load combustion using pulverized coal by providing a main channel to which the primary air is led by its changing-over by means of a distribution damper and a low load channel in a pulverized coal burner. CONSTITUTION:A distribution damper 3 is put on the solid line side in the figure during low load combustion. Then the pulverized coal and the primary air flow in the low load channel 5, where fine powder is separated by a separator 8, and the primary air 15 containing a higher proportion of pulverized coal enters a high concentration throat 9, and the primary air 14 which contains a lower proportion of pulverized coal and from which contains a lower proportion of pulverized coal and from which fine powder has been removed enters a low concentration throat 7. Consequently, even if pulverize coal concentration is reduced during low load, the concentration in the primary air 15 is maintained high, and excellent combustion is obtainable. The ratio of the primary air 14 and the primary air 15 is regulated by an air regulator 16 which regulates concentration of pulverized coal in air. On the other hand during high load, the distribution damper 3 is placed on the side of the broken line in the figure and primary air 1 is supplied through the main channel 4 and main throat 6. Since in this case the pulverized coal concentration is high, the primary air forms an internal circulation with the secondary air supplied by a swirler 11 to give excellent combustion. When the damper is at the neutral position, the primary air comes from throats 6, 7, and 9.

Title: Winding arm for slitter
Inventor: HASEGAWA KATSUMI
IPC: B65H18/04
Filed: 1989-05-17
Abstract: PURPOSE:To prevent axis movement of a winding core togetherwith a winding core chuck in a state that the winding core is hooked to the chuck during pull off of the chuck and to prevent displacement of a sheetform substance by a method wherein a core press means adapted to press the both end surface of the winding chuck is mounted to a winding arm. CONSTITUTION:A sheetform substance is wound around a winding core 10, and when winding of a given winding amount is completed, rotation of a winding chuck 11 is stopped. A so wound sheetform substance in roll is transferred from a winding arm 12, and is received by a truck to convey the sheetform substance to a subsequent process. A core press 40 is actuated so that the core press 40 pushes each of the end surfaces of the winding core 10, and effects regulation so that the winding core 10 and the wound sheetform substance in roll are prevented from movement in the direction of the axis of the winding core. As a result, since, when the winding core chuck 11 is pulled off from the winding core 10, a force in the direction of the axis of the winding core is generated, the wining core 10 and the sheetform substance wound therearound are not moved in the direction of the axis of the winding core through the action of the core press 40, and the sheetform is prevented from being displaced on a truck.

Abstract: PROBLEM TO BE SOLVED: To prevent the contamination of a decorative surface by the rust of a nail fixing a floor material onto a floor joist by interposing a sheet-shaped article having airtightness between the board of the floor material and the sliced-veneer decorative board of a surface. SOLUTION: The woody floor material is constituted in such a manner that a male tongue 4 and a female tongue 5 are formed to the end face of a woody board 2 such as plywood, a particle board, an MDF, etc., in thickness of approximately 5-12 mm and a sliced veneer 1 in thickness of approximately 0.2-1.0 mm is stuck onto a top face through a sheet-shaped article 3 in thickness of approximately 0.01-0.02 mm. The woody board 2 may also be configured by laminating the MDF on plywood through the sheet-shaped article 3. A synthetic resin sheet such as polyethylene, polypropylene, etc., having high airtightness is used as the sheet-shaped article 3.  The woody floor material is fixed by driving a nail 6 into a floor joist from the male tongue 4, but rust is generated in the nail 6 when the time passes for a prolonged term, and the iron of rust reacts with the lignin of the sliced veneer 1 and a decorative surface is contaminated when the iron of rust is propagated to the surface of the floor material. Accordingly, the contamination is prevented by the sheet-shaped article 3.

Title: Liquid crystal cell
Inventor: MOCHIZUKI MIYUKI
IPC: G02F1/1339
Filed: 1987-05-19
Abstract: PURPOSE:To reduce the probability of producing unevenness in cell interval in the vicinity of a liquid crystal injecting port without increasing the liquid crystal injecting time, by providing plural liquid crystal injecting ports. CONSTITUTION:Plural liquid crystal injecting ports 26 are provided and the opening length (b) of each port is decided in such a way that the interval between two substrates 20 and 22 in the vicinity of respective ports can be maintained almost constant when a sealing section 24 is hardened under pressure. Therefore, even when the opening length (b) is made shorter in order to obtain practically sufficiently uniform cell intervals, a problem of getting longer in liquid crystal injecting time can be avoided when the number of the injecting ports 26 is increased. Accordingly, the cell intervals can be uniformized without increasing the liquid crystal injecting time and, as a result, reduction in manufacturing yield can be prevented.

Abstract: PURPOSE: The urea synthesis mixture resulting from the reaction under conditions of specific NH 3 /CO 2  molar ratio, temperature and pressure is subjected to stripping with carbon dioxide under the same pressure as the reaction one at a specific temperature to inhibit the hydrolysis of urea as well as the formation of biuret, thus producing urea in high carbon dioxide conversion.  
     CONSTITUTION: The reaction of ammonia with carbon dioxide is effected at a 3/1W 5/1 molar ratio of ammonia to carbon dioxide under pressure of 150W250kg/cm 2 G at 180W200°C to prepare a urea synthesis mixture containing urea, water, unreacting ammonia and carbon dioxide. The urea synthesis mixture is tripped with carbon dioxide under the same pressure as the reaction one at 195W210°C to give the urea solution containing 10W15wt% of unreacting ammonia and having 3W3.5 molar ratio of remaining ammonia to carbon dioxide. The resultant mixture is sent to the second unreacting substance stripper under 10W30kg/cm 2 G at 150W170°C to separate ammonia with priority to decrease the ammonia content of the mixture to less than 8wt%. Then, the mixture is placed in the low-pressure separation zone where unreacting ammonia and carbon dioxide are separated to give a urea solution.

IPC: H02G1/14
Filed: 1987-05-20
Abstract: PURPOSE:To completely remove the remaining material of a sheath layer by stopping cutting of the sheath layer before it arrives at a core wire. CONSTITUTION:When a start button is pressed after a transmission line 2 is locked, hydraulic oil of a cylinder 45 is removed, and rollers 44 hold the line 2 by the force of a spring 46. Simultaneously, a motor 41 is rotated, and a cutter holder 38 is rotated at a slow speed. A hydraulic cylinder 53 simultaneously moves rearward a rod 51. This operation moves forward a cutter base 50 through a lever 56 to an axial center O to cut an aluminum layer 10. A cutter 49 is so controlled at this time as to stop at a position slightly before the part 9 of a steel. Then, hydraulic oil is applied from a port 45b, the three rollers 33 clamp the layer 10, and a saddle 35 moves rearward by a cylinder 36 while a cutter holder 38 is being rotated. Thus, the remaining innermost layer 10 not cut is broken and stripped off from the line 2. Thus, the layer 10 can be removed without remaining at a step cutting position without damaging the steel part 9 of the core wire.
