Filed: 1994-12-27
Abstract: PURPOSE: To always perform adequate image density adjustment by automatically measuring the surface density of an optional original by means of a sensor and controlling image forming condition to adjust the image density. CONSTITUTION: The output value of an ADS sensor with respect to the original is fetched from an input part 45 through an input/output port 44, and is stored in a RAM 43. Next, a micro CPU 40 reads the output value (d) of the ADS sensor with respect to the referential original surface density previously stored in the ROM 42, constants (a), (b), (c), and a secondary regression expression being VB (ADS)=a(Xmax--d)<2> +b(Xmax-d)+c, substitutes (d), (a), (b), (c), and Xmax inside the RAM 43 so as to calculate developing bias feed back amount VB (ADS). The micro CPU 43 limits the calculation result to, a specified ceiling value or under and outputs it to a developing bias power source 29 through the port 44, so that copying image density can be adequate in accordance with the surface density of the original by the control.

Title: Driving guide instructing system
Inventor: FUJIMOTO EISUKE
IPC: B60K23/00
Filed: 1987-12-23
Abstract: PURPOSE:To minimize the difference in a guide-driving by stepping a memory address based on pulses generated by a distance sensor after the number of the pulses satisfies specific conditions. CONSTITUTION:While a distance sensor 15 generates pulses W every time when an automobile moves for a prescribed distance, the sensor 15 generates a signal S to indicate the actual moving direction of the automobile. Occasionally, when the automobile travels on an inclined slope and a place having a level difference, the actual moving direction of the automobile becomes different from the operation direction of it. When this kind of phenomenon occurs at the time of a basic driving traveling and of a follow-up driving, it is supervised whether the number of the pulses W, which are generated by the sensor 15 from the time when the above-mentioned moving direction becomes different from the operation direction up to the time when both of them become coincident, and the number of pulses, which are generated after the actual moving direction of the automobile coincides with the operating direction of the automobile, become equal or not. The address of a non-volatile memory 12 is stepped based on the pulses W after both the numbers become equal, and a driving guiding instruction is executed by reading a basic traveling locus data from this memory 15. thus, erroneous data is never read, and the guide-driving instruction can be executed correctly.
