Title: Rubber roll
Inventor: HIRANO YASUO
IPC: F16C13/00
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To excellently adapt a rubber roll to an electrostatic recording device requiring various kinds of characteristics such as low hardness, medium resistance, high wet and surface smoothness by having a first layer made of polar rubber and a second layer made of a synthetic resin with specified thickness coated on the outer periphery of the first layer 1. SOLUTION: In a rubber roll, a first layer 9 made of polar rubber is formed in about 1 to 2 mm in thickness on a core bar 7 and a second layer 10 of a synthetic resin of a fluorine system, a silicon system and an urethane system is formed in about 10 to 100 μm on the first layer 9. By providing the second layer 10 in this way, a resistance value changes under high wet environments of the first layer 9. But, when this roll is used for a developing roll, unnecessary toner is prevented from sticking on the surface of the roll and characteristics such as a toner surface lubricant, lubricity and toner chargeability can be improved. Further, when the second layer 10 is formed by dispersing low resistance particle 11 such as metal in a material of the second layer 10, the second layer 10 acts as a developing electrode and image quality can be improved.

Title: Nonlinear 2-freedom degree pid controller
Inventor: KUWATA RYUICHI
IPC: G05B11/36
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To suppress intense fluctuation of a manipulated variable that is caused by the high frequency fluctuation of a controlled variable by setting the difference between a corrected control deviation and its target value at the controlled variables of both proportional and differential terms. SOLUTION: The inputted control deviation E is outputted as a corrected controlled variable PVa by a blind sector element 1. Thus, the variable PVa is not fluctuated even if a controlled variable PV fluctuates at a point near its target value SV and accordingly the high frequency fluctuation of a manipulated variable MV can be suppressed. A saturation element 3 is added to the input path of the deviation E against a differential element 11. Thus, a direct integrating operation is performed in a small range of the deviation E where the integrating operation is important and the generation of a steady deviation is prevented. When the deviation E exceeds its upper and lower limit value with its absolute value increased, the upper and lower limit value having their absolute value smaller than the deviation E are integrated.  As a result, the integrating operation is suppressed and an excessive integral signal I is also suppressed. Then an occurrence of overshoot of the variable PV is suppressed.
