Title: Ferrite carrier
Inventor: NOZAWA KEITA
IPC: G03G9/107
Filed: 1990-11-22
Abstract: PURPOSE:To provide a ferrite carrier capable of providing images with a stable and excellent image quality under high moisture circumstances by performing humidifying treatment in a manufacturing process. CONSTITUTION:Humidifying treatment is carried out for improving a surface characteristic in a manufacturing process. Namely, a ferrite carrier which is baked is heated to 50 deg.C (preferably 100 deg.C) or more and to which humidifying gas having 5wt.% (preferably 10wt.%, and more preferably 20wt.%) or more of included moisture content is supplied for treatment. With this humidifying treatment, the hydrophilic property on the surface of ferrite carrier becomes weak so that the charging property of ferrite carrier is stabilized under high moisture circumstances. It is thus possible to provide a such a ferrite carrier capable of providing stable images under high humidity circumstances.

Title: Motor power steering system
Inventor: OGISO YOSHINORI
IPC: H02P7/00
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To enhance neutral feeling by feeding a motor with a motor current depending on a target assist value and a friction compensation value and canceling the friction thereby enhancing the steering feeling and the returning of steering wheel. SOLUTION: When a right turn friction compensation value R is transmitted to a motor current control means 6, for example, a motor current control means 6 feeds a motor 3 with a motor current for generating a motor torque of same magnitude as the friction in the right direction. When a switching section 9 is switched by a decision means 8, a friction compensation value output section 7 outputs any one of zero, a right turn friction compensation value R or a left turn friction compensation value L. Any one of compensation value thus outputted is added by an adder 10 to a target assist value. Consequently, the motor current control means 6 feeds the motor 3 with a motor current depending on the target assist value and the friction compensation value.
