IPC: G03G15/08
Filed: 1989-09-05
Abstract: PURPOSE:To always and constantly maintain density and chromaticity of a transfer image by effectively compensating error in measured value of toner adhered quantity and feeding back to the control of a developing bias voltage value. CONSTITUTION:The toner adhered quantity of a test toner image formed on a surface of a photosensitive body drum 1 is optically measured by a reflective type photo sensor 15 which is constructed from LED 16 and a photo diode 17. The voltage value of developing bias responding to the adhered quantity which is the target is calculated based on an adhered quantity measured value, the developing bias of this voltage value is impressed, the test toner image is formed again, the adhered quantity is measured, the compensating value of the developing bias voltage is calculated, and a developing bias voltage value changing means is controlled based on this compensating value. Thus, even when the adhered quantity measured value of the test toner image is of a small range with a small rate of change, error is dissolved by a second compensating process, and the transfer image can be always and constantly maintained at a good density and chromaticity.

Title: Non-contact displacement measuring device
Inventor: YANAI SHIGEYASU
IPC: G21C17/06
Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of errors caused by the contact of a detector with an object to be measured when, for example, a change in the external form of the object to be measured such as a fuel cladding pipe in a nuclear reactor is measured. SOLUTION: Electromagnetic induction type detectors 1 to 3 are arranged at an interval of 120 degrees in the peripheral direction of a fuel cladding pipe 40. Amplitude of oscillation signals of oscillation circuits 1 to 3 is changed in accordance with displacement of a gap among them. Magnitude of the amplitude is detected in rectifying circuits 1 to 3. Size of the gap is obtained from the magnitude of the amplitude detected based on a calibration curve for the gap vs. magnitude of amplitude which is stored in advance in a signal computing circuit 44. Furthermore, displacement of a diameter of the fuel cladding pipe is obtained based on obtained size of gap in three directions.
