Title: Conveying method for coal for blowing into blast furnace
Inventor: KANBARA TAKAYUKI
IPC: C21B5/00
Filed: 1981-12-08
Abstract: PURPOSE:To control the quantity of air for combustion of pulverized coal in the stage of controlling the blasting rate into a blast furnace by using a part of the compressed air to be supplied to a hot stove as a carrier gas for the coal in blowing the coal into the blast furnace through its tuyeres. CONSTITUTION:The hot wind to be fed into a blast furnace BF is pressurized with a fan 1 and is fed into a hot stove HS via a flowmeter 2, by which the wind is heated to a high temp. The heated air is blown into the blast furnace through its tuyeres 5. In this case, part of the pressurized air is removed from the position T before entering the stove HS and is cooled with a cooler 9a. After the pressurized air is dehumidified with a dehumidifier 12, the air is pressurized up to prescribed pressure with a compressor 1b. The pressurized air is cooled with a cooler 9b and is stored in a receiver tank 13. The pulverized coal P stored in a tank 6 for pressure feeding is removed from the removing port 7 in the bottom part and is blown by the compressed air of a receiver tank 13 into the furnace BF through the tuyeres 5. Since the combustion of the coal and the blasting rate into the blast furnace are controlled unitarily, the blast furnace is operated stably and easily.

Abstract: PURPOSE:To prevent deterioration of drivability and exhaust emission by preventing aberration of an air-fuel ratio in switching control phases of a main fuel supply and an auxiliary fuel supply. CONSTITUTION:There are provided a fuel throttle valve 15 which controls a main fuel supplying rate and an injector 17 which controls an auxiliary supplying rate. In an ECU 38, an air-fuel ratio feedback control is carried out by means of the fuel throttle valve 15 under a high load condition, and it is carried out by the injector 17 under medium and low load conditions. In the ECU 38, the air-fuel ratio feedback control is started, when the control phases are switched from that by the injector 17 to that by the fuel throttle valve 15, after an air-fuel ratio amending factor(FAF) used correspondingly to the control phase by the fuel throttle valve 15 after switching is initialized to be a value 1.0. Accordingly, even when an amending rate per one unit with regard to the FAF are different in both the control phases, the air-fuel ratio immediately after the switching of the control phase is properly amended.

Title: Rotation force transmission device
Inventor: TSUDOMI HIROSHI
IPC: F16H35/00
Filed: 1993-07-15
Abstract: PURPOSE:To perform high-efficient transmission of movement energy through the increase of a rotation force by a method wherein a rotation force transmission device comprises a cylindrical rotary body; an impact absorbing part formed on the inner peripheral wall thereof; a rotary shaft connected to a rotation drive means; rotary blades formed on the rotary shaft; and a transmission shaft through which rotation is transmitted, and the rotary body is sealed and filled with fluid. CONSTITUTION:When an electric motor 24 is driven, a rotary shaft 20 is rotated togetherwith rotary blades 22a-22d, and fluid with which a rotary body 14 is sealed and filled is peripherally rotated. In this case, a smooth and rapid vortex layer is generated around the rotary blade. A turbulence layer of circular fluid is generated along the innermost end parts of impact absorption plates 18a-18d arranged to the inner wall of the rotary body 14. The turbulence layer is generated owing to an impact absorbing plate impeding the smooth flow of fluid in the rotary body 14. When, compared with the number of revolutions of the rotary shaft 20, the number of revolutions of the rotary body 14 does not exceeds that of the rotary body but unlimitedly approaches it, the wall of the turbulence layer is decreased in thickness and the generation of energy of fluid is reduced. On the contrary, the inertia moment of the rotary body 14 is high and a rotation force is increased.

Title: Printer
Inventor: YAMANAKA SHUICHI
IPC: B41J29/38
Filed: 1989-08-02
Abstract: PURPOSE:To improve the utilization efficiency of a memory by comparing the ID value of a program housed in a nonvolatile memory and the ID value of a program during current execution and rewriting the ID value of the pro gram housed in the nonvolatile memory to an initial value regarding the pro gram during current execution when both ID values differ. CONSTITUTION:A region in which an ID value imparted to a program is housed is formed into a nonvolatile memory 4 besides a region, in which data such as the use conditions of a printer employed in the program is housed, and a region in which a hash value is housed. Hash is checked on the basis of the hash value given to the nonvolatile memory 4. In the normal case the content of the ID-value housing address of the nonvolatile memory 4 is set to a register R1, and an ID value imparted to the program during current execution is set to a register R2. When both ID values are not equalized, the content of the nonvolatile memory 4 is rewitten to the initial value (also including the ID value) of the program during current execution. Accordingly, an unnecessary memory region is removed and the memory can be utilized efficiently, and the memory can be used without being subject to the effect of the content of the program before changeover.
