Title: Burner for powdered solid fuel
Inventor: TANAKA SHINJI
IPC: F23C99/00
Filed: 1986-12-17
Abstract: PURPOSE:To make it possible to maintain a constant speed of the burner ejecting powderes solid fuel from a burner nozzle of a small diameter even if a load varies by providing a plurality of gassification agent supply pipes internally and providing at least one of them with a burner which has a flow passage cut-off valve. CONSTITUTION:Pulverized coal is supplied to a nozzle for ejecting pulverized coal as a mixed phase flow of a pulverized coal and a carrier gas and ejected from a pulverized coal ejecting nozzle outlet opening 14. A gassification agent passes through a flow rate adjusting valve 30 and via a gassification agent carrying pipe 33 and divided in four ways to be sent through gassification agent branch pipes 24-27, flow passage cur-off valves 2-3, and gassification agent supply openings 6-9 to gassification agent supply pipes 19-22 of a burner main body. The gassification agent that entered the gassification agent supply pipe is branched in two directions respectively which are symmetrical with respect to the pulverized coal nozzle outlet opening, and then jetted out from gassification agent jetting-out holes 15-18. This gassification agent accelerates the pulverized coal that is jetting out and mixes it and makes it contact with the out-side to gassify. When a load to the gassification furnace varies, a valve control device 31 detects the opening of the flow rate regulating valve 30 and conducts opening and closing of the flow channel cur-off valves 2-5 in an order which is beforehand set according to the degree of opening of the valve 30.

Abstract: PURPOSE: To obtain a very high circuit integration density with a very small required area by overlapping a source region that is placed on a gate electrode of a transistor(TR), an insulation layer and recrystallized silicon layer and formed in the recrystallized silicon layer on a conductive contact in an asymmetrical extension part of a groove opening part. CONSTITUTION: A selection TR is formed in a recrystallized silicon layer 8 doped with boron. Thus, at first a gate oxide layer 14 is grown, and a gate electrode 15 made of a doped polycrystal silicon or a metal silicide is depositted on the layer 14. The gate electrode 15 is in use as an implantation mask when arsenide ions are implanted to form source/drain regions 16a, 16b. In this case, an arsenide region 16a is taken into account that the region 16a is overlapped onto an n<+> contact 11 of a capacitor as good as possible. Thus, charges are stored in an inside 5 of a trench, and since no soft error reaction is caused by providing a box insulation part 13 between adjacent trenches, a sufficient capacitance is obtained.

Filed: 1987-11-28
Abstract: PURPOSE:To simplify a maintenance by comparing the transmission messages of at least two points of a transmission network, and executing a coupling in routes different by softwares when node address in the transmission messages do not coincide. CONSTITUTION:Since the node addresses of a message Ma existing in a receiving buffer 4 and a message Mb existing in a receiving buffer 5 do not coincide with each other when the transmission paths at an A side and a B side are interrupted by an accident, a comparing part 2 sends a signal to indicate the discrepancy to a coupling part 3.
