Title: Electrostatic recorder
Inventor: MINAMI KOJI
IPC: G03G15/047
Filed: 1987-11-18
Abstract: PURPOSE:To destaticize only the electrostatic charge region of a photosensitive body and to prevent generation of an optical memory by intermittently operating an erasing means in association to a charging means. CONSTITUTION:This recorder is equipped with the means for intermittently and electrostatically charging the continuously moving photosensitive body 20 by the charging means 22 and the means for intermittently operating the erasing means 11 in association to the operation of the charging means 22.

Title: Motor controller
Inventor: NAGASAWA MASAHITO
IPC: H02P29/00
Filed: 1989-11-08
Abstract: PURPOSE:To achieve an intensive disturbance suppressing effect without requiring a sophisticated speed detector nor a large rotary mechanism by returning an amount of disturbance, estimated through a disturbance estimating unit, through a disturbance suppressing loop to the input of a motor. CONSTITUTION:A disturbance estimating unit 11 constituted according to minimum observer method based on modern control theory is provided, in addition to conventional phase control loop and speed control loop, in order to estimate the amount of disturbance. Thus estimated amount of disturbance is then fed forward to the control voltage of a motor 4 through a disturbance suppressing loop. The disturbance suppressing loop returns the amount of disturbance, estimated through the disturbance estimating unit 11, to the input of the motor 4. Consequently, fluctuation of rotary speed or rotary phase of the motor 4 due to disturbance can be suppressed over a wide disturbance frequency band, while furthermore an intensive disturbance suppressing effect can be achieved. Highly precise and expensive speed detector is not required, nor a large and heavy rotary mechanism is required for the motor 4 for achieving such effect.
