摘要： In an electrophotographic apparatus, densities of toner images of a light reference mark and a dark reference mark are detected by a density sensor, and input voltages such as an illumination power source voltage and an electrostatic charge voltage are varied by small values on the basis of a difference between detected densities and an aimed density, the small values are determined on the basis of a predetermined qualitative model. Subsequently, a line width of the toner image of a reference mark having a striped pattern is detected by a line width sensor and a developer bias voltage is varied by a small value in a similar manner as mentioned above.

摘要： An optical disc driving apparatus is provided for the access control system with respect to the optical disc, comprising emphasizing circuits which compensate for a decrease in the frequency response of a reproduced signal from an optical head and further comprising peak detection circuits for detecting envelopes of the output signals. The emphasizing circuits and peak detection circuits are not used for processing of the tracking servo sensor signal, therefore the compensation amount need not be accurately controlled. The characteristic of the reproduced signal of the optical disc is effectively utilized, thereby enabling the compensation amount to be used over a wider range from about a proper value to an excessive value. In addition, being able to use the compensation amount over a wider range results in a reduction in the number of separate stages of compensation.
摘要翻译：提供了一种光盘驱动装置，用于相对于光盘的访问控制系统，包括强调电路，其补偿来自光学头的再现信号的频率响应的降低，并且还包括峰值检测电路，用于检测输出信号。强调电路和峰值检测电路不用于跟踪伺服传感器信号的处理，因此不需要精确地控制补偿量。有效地利用了光盘再现信号的特性，从而能够在从适当值到过大值的较宽范围内使用补偿量。另外，能够在更宽的范围内使用补偿量导致单独的补偿阶段的数量的减少。

摘要： A recording light beam from an argon laser is modulated with an electrical recording signal and then recorded on a rotating disc-shaped record medium. Immediately after this recording, a recorded signal on the record medium is reproduced with a light beam from a helium-argon laser and converted into an electrical signal. Duty cycles of both signals are sensed by respective duty cycle sensors. A differential amplifier produces a differential signal between the sensed duty cycles and supplies it to an optical modulator arranged to control the output of the recording laser. The modulator controls the recording light beam to its optimum light level for recording in response to the differential signal which was detected just before its modulation.
