Title: Controlling method for wind box damper
Inventor: MATSUMOTO MASAHISA
IPC: F23C9/08
Filed: 1985-12-24
Abstract: PURPOSE:To provide a superior sensing of a flame in a main burner without transiently increasing an amount of recirculated gas per one burner while keeping a required feeding recirculation gas by a method wherein the recirculation gas is fed into a furnace also from a recirculation gas feeding compartment of a non-firing burner in response to an increase in the feeding volume of the recirculation gas when a boiler load is varied. CONSTITUTION:Discharged gas fed only from a recirculation gas feeding compartment adjacent to an operating burner stage is also fed from an unused stage burner which is not firing. That is, any degree of opening of SGR damper at the unused burner stage is applied in response to a boiler load, a recirculation gas feeding volume per burner stage during its firing condition is decreased even if the recirculation gas is fed in view of controlling of steam temperature and NOx in the discharged gas, and further a separate function of a unit for setting a degree of opening of the damper and a previous control function when a load is varied are added. The recirculation gas is fed into a furnace from the recirculation gas feeding compartment adjacent to the non-firing burner to keep a steam temperature without deteriorating a flame sensing of the firing burner and thus a smooth transmission of load can be performed.

Filed: 1986-12-08
Abstract: PURPOSE:To ensure the sealing of a semiconductor chip by a simple method, by forming and hardening a bank part at the outside of the semiconductor chip before the semiconductor chip is covered and hardened with a thermosetting resin. CONSTITUTION:A thermosetting resin such as, e.g., epoxy and silicone, is discharged through a nozzle 25 of a resin discharge device 24 around a semiconductor chip 12, and an endless annular bank 17 is formed. When the bank 17 is formed, a substrate 14 is heated for several minutes in an oven, and the bank 17 is hardened. When the hardened bank 17 is formed, contamination of the semiconductor chip 12 and breakdown of metal wires 15 are prevented, and moisture resistance and heat resistance are improved. The inside of the bank 17 is filled with a thermosetting resin furthermore, and a covering layer 18 is formed. Thus the semiconductor chip 12 is covered. Since the bank 17 is formed before the formation of the covering layer 18, the outflow of the thermosetting resin is prevented by the bank 17 even if the inside is filled with the thermosetting resin having relatively low viscosity.

Abstract: PURPOSE:To prevent the overflow of a control input caused by the input saturation of a plant by replacing the unstable elements of a compensator with the compensation elements MO, MD and L of a stable transmission function matrix and putting a limiter into a loop including the elements MO and MD. CONSTITUTION:The controller of a plant P receives the input disturbance d1 and the output disturbance d2, receives the input of the control input (u) which is saturated at the upper limit uU and the lower limit uL, and outputs the output (y). Then the controller inputs the deviation (e) between the output (y) and its target value (v) and outputs the input (u). When the linear relation is secured between the input (u) and the deviation (e), u=Ce is satisfied in terms of a transmission function matrix. This matrix C constructs a feedback compensator C. The compensator C contains a compensation element MO which inputs the input (u) and produces the intermediate arithmetic value v1, a compensation element L which inputs the deviation (e) and produces the intermediate arithmetic value V2, a subtractor which inputs the value V1 and V2 and outputs the comparison value V3 between both value V1 and V2, and a compensation element MD which inputs the value V3 and outputs a 4th signal V4.
