Title: Image forming device
Inventor: OKABE HARUHIKO
IPC: G03G15/08
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To accurately estimate the consumption of toner, with a simple and inexpensive constitution by providing a total charge amount detecting means for obtaining the total amount of charge stored in a charge storage means and an estimating means for estimating the consumption of the toner, based on the total charge amount. SOLUTION: A laser driving pulse Pr outputted from a PWN (pulse width modulation) circuit 2 is inputted to the base of an NPN type bipolar transistor (NPN) 303. Since this NPN 303 becomes an ON state only for a time corresponding to the pulse width of the laser driving pulse Pr , the charge corresponding to the ON time of the pulse width is stored in a capacitor 305. Therefore, when the laser driving pulse Pr is successively inputted, the terminal voltage V0 of the capacitor 305 shows a voltage represented by the total of the pulse width of the laser driving pulse Pr . Consequently, the consumption of the toner can be accurately estimated with the terminal voltage V0 of the capacitor 305.

Title: Method and device for picture conversion
Inventor: KUBOTA MINEO
IPC: G06T3/40
Filed: 1991-12-28
Abstract: PURPOSE:To obtain the picture of desired reduction ratio or enlargement ratio extending over a wide selection range of the reduction ratio or the enlargement ratio and in addition, through small-scale configuration by accumulating succes sively the decimal fraction part of the scale factor of reduction or enlargement. CONSTITUTION:In the case that a reduction mode is selected, the decimal fraction part of the reduction ratio is set in a C register. For instance, in the case that the reduction ratio 72% is selected, 0.72 is set in the C register. Simultaneously, FF of a hexadecimal number (0.99 in decimal number) is set as an initial value in an accumulator A (V). A CPU 1 accumulates the decimal fraction part of the scale factor in a sub-scanning direction by the accumulating part 11, and if the accumulator A (V) has overflowed before, it recognizes that line to be an effective line, and it shifts to reading operation in a main scanning direction. In the case that the accumulator has not overflowed, it recognizes that line to be a thinned object line, and it does not execute the reading operation in the main scanning direction. Read processing in the main scanning direction is processed similarly to the sub-scanning direction by accumulating the decimal fraction part by the accumulating part 10.

Title: Apparatus for removing noncombustible in fluidized bed furnace
Inventor: KAWAI TAKASHI
IPC: F23G5/50
Filed: 1991-12-27
Abstract: PURPOSE:To provide the title apparatus which satisfactorily discharges uncombustibles from the inside of a fluidized bed, by a control means wherein when a pressure signal detected exceeds a preset value, flow control valves are fully opened and the revolution speed of an uncombustible-taking out conveyer is increased. CONSTITUTION:While noncombustibles are being accumulated within a fluidized bed, air pressure in a diffusing pipe 3 comes to rise. This pressure is detected by a pressure gauge 21 and is inputted in a controller 23. When a pressure signal 22 detected increases and exceeds a definite value, the controller 23 outputs an opening command signal 24 to each of opening controllers 4 in order that all of flow control valves 5 are fully opened. At the same time, controller 23 outputs a speed command signal 25 in order that the revolution speed of a variable speed motor 11 for an uncombustible-taking out conveyer 12 is increased and the discharge of waste is increased. In this way, the fluidization of the fluidized bed is intensified as a whole and the uncombustibles are allowed to flow. In addition, since the discharge by means of the uncombusible-taking out conveyer 12 is increased, the uncombusibles within the fluidized bed are effectively discharged.
