Title: Concentration detector for developer
Inventor: ASANUMA MASAHITO
IPC: G01N27/72
Filed: 1985-10-29
Abstract: PURPOSE:To detect efficiently the concentration of a developer by forming a sensor for detecting the transmissivity of a developer carried by a sleeve and arranging a baffle plate on the lower part of the sensor to stabilize the quantity of the developer flowing into the sensor. CONSTITUTION:The developer carried by the sleeve 14 passes a developing area opposed to a photosensitive body 11 and then passes the sensor 21 to detect the transmissivity of the developer in accordance with the toner density. When the transmissivity is larger than that of a reference toner density value, toner is fed from a toner feeder into a developing tank 13. The developed developer on the sleeve 14 is carried to the sensor 21 by a carrying blade. Since the baffle plate 25 is arranged near the sensor 21, partial flow of the developer is suppressed and the stay of the developer can be generated in the sensor 21. Then, a new developer 17 is carried by the carrying blade. Consequently, the quantity of the developer 17 flowing into the sensor 21 is held at a fixed value. Thus, the stable concentration of toner can be detected.

Filed: 1994-09-14
Abstract: PURPOSE: To realize an errorless detection by providing a circuit for detecting first and second binary serial codes divided by N and operating the exclusive OR thereof thereby outputting an incremental signal. CONSTITUTION: In order to obtain incremental signals 1A, 1B, output signals DA2-DA5 and DB2-DB5 are inputted to an logic operation circuit 6 comprising EX-OR gates G1-G6. The gates G1-G4 output operation output signals DG1-DG4 while the gate G6 outputs the incremental signal 1A in response to the output signals DG3, DG4 and the gate G5 outputs the signal 1B in response to the DG1, DG2. At the variation point of any one of the output signals DA2, DB2, DA3, DB3, other three signals are in a stable region and thereby only one variation point is present in each dived region. Since the 1B is obtained through division by four signals and employed for judging the region of other signal, errorless reading is realized.

Abstract: PURPOSE:To enable a voltage stress, etc., to be verified by charging a capacitor to a specified testing voltage and giving ignition/extinction signals to a switching element of a self-excited converter. CONSTITUTION:A capacitor C of a self-excited converter 10 is charged to a specified test voltage by a DC charger 20. After that, when ignition signals a and b are given to GTOG1 and G4 based on a command from a pulse signal generator 30, a current flows from the capacitor C to a load L through the GTOG1 and G4 for a period of 1. A load current I increases with a current change rate which is obtained by dividing a charge voltage by a load impedance. When an extinction signal a' is given to the GTOG1 at a point A when a specified current value in testing is reached, a current of the GTOG1 is shut off and the load current I flows through a feedback diode D2 of the GTOG4 and G2 for a period of 2. Furthermore, when an extinction signal b' is given to the GTOG4 at a point B, a current of the GTOG4 is shut off and the load current I returns to a DC capacitor through the feedback diodes D2 and D3 for a period of 3.

Continuously, when second communication reference pulses are consecutively outputted/transmitted from the checker 21, the CPU 17 of the camera 11 executes input as the second communication reference pulses. Then, the CPU 17 measures the pulse width and period and stores them in the memory, when the signal is inputted.
