Title: Toner density controller
Inventor: NOGUCHI KOUICHI
IPC: G03G15/08
Filed: 1982-07-07
Abstract: PURPOSE:To adjust the oscillation frequency of the oscillator of a toner density controller easily when toner density is measured by using a detection coil, by composing the oscillator of an amplifying element with phase characteristics and varying a source voltage. CONSTITUTION:A power source circuit 27 is equipped with a three-terminal regulator 28 and a variable resistor 29 and its output voltage VDD is variable. The oscillator 30 consists of inverting and amplifying elements 31 and 32 composed of C-MOS inverters and having phase characteristics to the source voltage VDD, and the resonance circuit 35 consisting of the detection coil 18 and a resonance capacitor 25. When the toner density varies, the inductance of the coil 18 varies, so the oscillation frequency varies. This is counted by a counter to adjust the supply amount of toner. Variance in oscillation frequency based upon the coil 18 and capacitor 25 is corrected by a resistance 29. The circuit 27 uses an element with temperature dependency to realize temperature compensation as well.

The detected potential value is inputted in an arithmetic circuit 21 and the detected value is compared with a preset reference potential value, and then, a correcting value for charging is calculated from the difference between the detected value and reference value and the changing rate of the electric potential in the lapse of time. Then outputs of discharging devices 12 and 13 are corrected in accordance with the calculation. During the period when a slit 96 is closed by a light shielding member 91 and a drum 10 is shield from lights at every cycle, the electric potential at the dark section of the drum 10 is detected and correction and control of the electric potential of the drum are performed. Therefore, photographic fogs at the image surface and jumps of thin characters and fine lines can be eliminated.

IPC: G10H7/02
Filed: 1995-04-20
Abstract: PURPOSE: To provide a DSP which performs complex arithmetic processing efficiently, and economically at a high speed. CONSTITUTION: Plural DSPs 1 to 4 are parallelly installed to divide a series of arithmetic processing-synthesis or processing of aimed sound into plural processing sections and to make these DSPs share the processing. Each DSP is commonly connected with a first and a second buses so that the parameters required for arithmetic processing are distributed and inputted to each DSP through the first buss, and the results of arithmetic processing of each DSP are transmitted to other DSPs or output ports through the second bus. A DSP fetches the output data from other DSPs through the second bus to apply specified arithmetic processing to the fetched data, and the aimed sound signal processing is carried out by combining the processing of plural DSPs 1 to 4.  When conducting sound signal processing in a time sharing manner through plural channels, time-sharing channel timing of each DSP is independently established. And, by setting synchronous sound production designation data for every channel, synchronous sound production is controlled in plural arbitrary channels.
