Title: Automatic position controller
Inventor: OBO RYOSAKU
IPC: G05D3/12
Filed: 1990-06-22
Abstract: PURPOSE:To reduce the production cost and to decrease the parameter adjustment items by outputting a velocity reference command signal to a drive system from the acceleration and deceleration reference signals produced based on the position and initial position deviations. CONSTITUTION:A storage circuit 12 inputs a position deviation 4 between a target position 1 and a present position 2 of a control subject and stores the initial position deviation set at start of the control. An acceleration velocity reference circuit 11 produces an acceleration velocity reference signal from the deviation 4 and the initial position deviation. At the same time, a deceleration velocity reference circuit 10 produces a deceleration velocity reference signal from the deviation 4. Then the smaller one of both velocity reference signals is selected by a minimum value selection circuit 13 and a velocity reference command signal is outputted to a drive system. Thus a conventional ramp function generator can be omitted. As a result, the production cost of an automatic position controller is reduced and the parameter adjustment items can be decreased.

Title: Frequency conversion circuit
Inventor: MORI EIJI
IPC: G01R23/173
Filed: 1994-06-22
Abstract: PURPOSE:To remove the mixer communication signal from a local oscillator significantly from the output signal of a mixer by providing a variable phase shifter, a variable attenuator, a directional coupler, and a control section. CONSTITUTION:A variable phase shifter 10 outputs the signal from a local oscillator 50 while shifting the phase thus forming a phase angle reverse to that of a mixer communication signal 50a. The phase shifter 10, a variable attenuator 20 and a directional coupler 30 synthesize an inverted signal of the mixer communication signal 50a thus canceling the disturbance signal 50a selectively. A control section 40 receives a frequency setting data signal of sweep step frequency being delivered from a ramp voltage generating section 51 to the oscillator 50. A phase angle data corresponding to the frequency and an attenuation value data are then read out from a parameter memory 42. The data is delivered to corresponding phase shifter 10 and attenuator 20 in order to cancel the signal 50a. When the intermediate frequency f110 is close to the oscillation frequency f100 of the oscillator 50, the signal 50a is canceled thus eliminating the effect of the oscillator 50.

Title: Contact electrifying member for electrophotography and electrophotographic device
Inventor: SAKOGAWA KOICHI
IPC: C09D201/00
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To prevent the adhesion of soil even in a long-term use and to obtain a clear and distinct image by forming the contact surface of a contact electrifying member with an electrophotographic photoreceptor by using a hydrophobic elastic body and setting the pure water contact angle of the surface thereof to a specified value or more. SOLUTION: The contact surface 4 of an electrifying mechanism 3 with the electrophotographic photoreceptor is formed of the hydrophobic elastic body, and the pure water contact angle of the surface is set to >=90 deg.. By setting the pure water contact angle of the outermost layer of the contact electrifying member to >=90 deg., the adhesion of contaminant such as residual toner is prevented. To put it concretely, it is desirable to set to >=95 deg., and more desirable to set to >=105 deg.. There is no limit to the structure of the contact electrifying member particularly and an electrifying roller, an electrifying blade, an electrifying brush and an electrifying film are used as the electrifying member, but the electrifying roller is most suitably used.  Even though the pure water contact angle material property of the resin used for the base of the outermost layer is low, the outermost layer whose pure water contact angle material property is high is obtained by dispersing inorganic particles, desirably, surface hydrophobic inorganic particles.
