IPC: F23K3/02
Filed: 1990-08-08
Abstract: PURPOSE:To secure the coal output according to coal output instruction signal even if the temperature at the outlet of a coal pulverizing machine changes and provide stability in control by adjusting the flow rate of the air for pneumatic transportation by using correction signals of coal output and temperature which take in consideration the change in the coal output due to a change in the temperature at the outlet of the coal pulverizing machine. CONSTITUTION:If the detected temperature signal 15 of a temperature sensor 14 which detects the temperature at the outlet of a coal pulverizing machine changes against a set temperature signal 16, the temperature difference signal 3 that is either positive or negative by the subtraction in a subtractor 32 is outputted to a function generating device 33 for converting coal output. The temperature difference signal 31 is converted to positive or negative coal output and temperature correction signal 34, and the coal output and temperature correction signal 34 is added to a coal output conversion signal 25 by an adder 35. The coal output conversion correction signal 36 thus obtained is introduced to a subtractor 27 and it is subtracted from a coal output instruction signal 26 and the opening of an adjustment damper 12 for the flow rate of the air for pneumatic transportation is adjusted. Accordingly it is possible to carry out stable fuel control by catching the variation in the coal output even against the variation in the temperature at the outlet of the coal pulverizing machine.

Abstract: PURPOSE:To increase the expression tones of charge controlled ink jet recording by changing the quantities of partial overlapping of dots, separation of dots, etc. of deflection directions. CONSTITUTION:The dot pitch D1, D2, is treated as the standard. In this case at every stage of electric charge, a charge voltage is changed within a specified extent wherein a deflection sliding less than 1 dot pitch is given, and by introducing a sliding which is less than 1 pitch from a standard pitch the numbers of expression tones are increased. By the above, the recording concentrations of a' and b' that have upward slidings by the half pitch d become the contentrations between the recording concentrations of (a) and (b), and the recording concentrations of (b) and (c). By introducing a half pitch sliding of upward or downward only or further by introducing upward or downward pitch sliding of other than a half pitch, the numbers of expression tones can be further increased.
