Title: Control device for copying machine
Inventor: TOMOSADA MASAHIRO
IPC: G03F7/20
Filed: 1983-08-10
Abstract: PURPOSE:To maintain always a copied image at adequate density by detecting the quantity of the light reflected from an original and the surface condition of a photosensitive body and controlling selectively a mode for setting automatically the density of the copied image and a mode for setting manually said density according to the two detection signals. CONSTITUTION:The detection signal from a potential sensor which detects the surface condition of a photosensitive body is inputted from a terminal P1 and the potential of the photosensitive body is measured by a Miller integrator consisting of a resistor R3, an operational amplifier Q3 and a capacitor C1. The quantity of the light reflected from an original is detected via a photodetecting sensor 9 by Miller integrator consisting of a resistor R4, an operational amplifier Q2 and a capacitor C2. The output from the Q3 is inverted and amplified by an operational amplifier Q5 and is compared with the output from the Q2 by an operational amplifier Q6. When the difference between the two outputs is a prescribed value or above, a switch element Q10 is turned off and a switch element Q11 is turned on to change over automatic setting to manual setting. The output voltage from a variable resistor VR for manual setting of density is then outputted to a terminal P5. The copied image is thus always maintained at the adequate density.

Title: Differential controller
Inventor: OUCHI MITSUSACHI
IPC: B60K23/04
Filed: 1987-06-12
Abstract: PURPOSE:To enable improvement in turning performance and traction by comparing a calculated rotational speed difference between right/left wheels with a reference rotational speed difference in response to a vehicle speed and a steering angle, and controlling an operating means in such a way as to reduce a differential limit amount when the calculated value is smaller than the reference difference. CONSTITUTION:A controller 24 reads a reference rotational speed difference omega0 on the basis of a vehicle speed U and a steering angle delta, calculates the absolute value DELTAomega of rotational speed in right/left driving wheels, and subtracts the reference rotational speed difference omega0 from the value DELTAomega so as to determine a control function omega, thereby judging positive/ negative sign of the function omega. And next, in the case of a positive function omega, the controller 24 determines a pressure P in response to the function omega so as to determine current I required for obtaining the pressure P. When the current I is outputted to the current control decompression valve 70 of an operating means 26, friction force increasing as the function omega becomes large is generated in a limiting mechanism 12, thereby resulting in differential limit. Meanwhile, in the case of a negative function omega, the controller 24 sets P and I to P0 and I0, respectively and outputs a control signal. The differential limit isn's effected in the mechanism 12 when P0 and I0 are zero so that a differential device can freely perform differential operation.
