Title: Detection system for toner concentration
Inventor: SANO HIDEAKI
IPC: G03G15/00
Filed: 1980-06-30
Abstract: PURPOSE:To maintain relative toner conc. with respect to the concn. of paper constant and eliminate detection errors for the vertical movement of the paper by correcting the errors in the detection output of the optical density of a toner mark by the output of the optical density of the paper. CONSTITUTION:Detecting heads 21, 22 for density are provided in a position where the toner mark MK on paper 3 does not pass and where it passes, and these detect the optical density of the paper and the optical density of the mark MK, respectively. The outputs thereof are negated of common components of both by a differential amplifier 4, and are compared with set values in a detecting circuit 6, according to which a toner is replenished. Thereby, only the toner conc. is contained in the output because the common components are negated by the amplifier 4 despite the occurrence of a change in the density of the paper itself and the vertical movement of the paper owing to its transfer, whereby the relative toner concn. with respect to the density of the paper is made constant. The output changes owing to the vertical movement of the paper are roughly equal with both heads, and the errors thereof are eliminated.

Filed: 1984-05-07
Abstract: PURPOSE:To prevent degradation of the engine performance, by providing a means for correcting an operational condition parameter in a storing means when two parameters representing the operational conditions of an engine are inconsistent with each other and preventing the ari-fuel ratio from becoming too lean at the time of accelerating the engine. CONSTITUTION:A first timing generating means produces timings at predetermined time intervals while a second timing generating means produces crank timings at intervals of a predetermined crank angle of an engine. Further, a comparing means makes comparison between an operational condition parameter AD in a storing means at the time of the latest crank timing and that AD0 at the time of the previous crank timing. In case that the above two parameters are inconsistent with each other, a correction means corrects the operational condition parameter AD in the storing means. Thus, since the air-fuel ratio is prevented from becoming too leant at the time of accelerating the engine, it is enabled to prevent degradation of the engine performance.
