Abstract: PURPOSE:To control the amount of toner supplemented to a developer by winding a coil in an E-sectioned material with high magnetic permeability, and detecting variation in the toner density of the developer in the form of variation in the inductance of the coil. CONSTITUTION:An E-sectioned ferritic core 11 made of a magnetic material with high magnetic permeability is wound with a coil 12 at the center part.

Title: Smoke detector
Inventor: IKEDA SHINJI
IPC: G01N27/04
Filed: 1985-08-08
Abstract: PURPOSE:To perform detection with invariably high precision and simple structure by detecting the sticking-incineration period of carbon particles in exhaust gas between electrode from the detected value of a current detecting circuit and outputting a pulse signal corresponding to the period. CONSTITUTION:When smoke in exhaust gas, i.e. carbon particles stick between platinum electrodes 11 and 12, a current begins to flow between them and a voltage signal VA increases with the amount of the stuck carbon particles. When the signal reaches a reference level VB, the carbon particles fire themselves and burn and the voltage signal falls to 0 again. The sticking-incineration period of the carbon particles varies with the amount of carbon particles in the exhaust gas, i.e. smoke concentration. Then, a comparator 33 compares the signal VA with the level VB to output a pulse signal VS which goes up to a high level when VA>VB, and then the signal VS varies at a period corresponding to the smoke concentration. Consequently, the signal VS is used as an input signal to a smoke controller.
