Title: Ac amplifying circuit
Inventor: SANO YOSHIAKI
IPC: H03F1/30
Filed: 1982-03-30
Abstract: PURPOSE:To stabilize the output bias, by connecting commonly bases of two transistor (TR) and connecting a current mirror circuit to the collector side. CONSTITUTION:Currents flowed to resistances R1 and R2 for non-signal are equal to each other by the function of a current mirro circuit CM. When the base current is ignored, a collector current I1 of a TR Q1 is equal to the emitter current. As a result, all of the emitter current of the TR Q1 is flowed to the resistance R1. The current which is flowed to a terminal T2 to a negative feedback signal is inputted does not exist. The signal outputted from the collector of the TR Q1 is amplified in an amplifier A and is outputted from a terminal T3. A feedback signal is given from the terminal T3 to the terminal T2. Since the current is not flowed to and from the terminal T2, the output bias in the terminal T3 is determined only by resistances R4 and R5, and the output bias is not affected by a power source voltage or the like and is stabilized.

Title: Finely powdered coal burner and finery powdered coal boiler, and method for combustion of finely powdered coal
Inventor: KOBAYASHI YOSHINOBU
IPC: F23C99/00
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To improve the reduction performance of NOx upon combustion by providing finely powdered coal concentration adjusting means for separating finely powdered coal concentration of a mixed flow of finely powdered coal and primary air in a finely powdered coal infection nozzle such that an outer periphery side is relatively higher than an axial side. SOLUTION: An annular particle flow passage adjuster 34 is arranged between a liquid fuel nozzle 5 and a primary air flow passage 30 for changing the size of an internal peripheral wall of a primary air flow passage 30. At a rapid expansion part of the particle flow passage adjuster 34 on the side of a fire furnace a primary air infection flow for conveyance of finely powdered coal and fine particles entrained with the primary air infection flow spread radially and are lowered in their infection speeds. Against this, finely powdered coal particles having relatively larger particle diameters do not spread owing to inertia force so much as the flow of the air without following the flow of the air.  Accordingly, the particle flow passage adjuster 34 forms a higher region of finely powdered coal particle concentration on an outer peripheral wall of the primary air flow passage 30 while it forms a lower region of the particle concentration on an internal peripheral wall of the primary air flow passage 30.
