摘要： A steering control section has a first steering angle correction amount calculating section, a second steering angle correction amount calculating section, and a motor rotational angle calculating section. The first correction amount calculating section calculates a first correction amount based on a vehicle speed and an actual steering wheel angle. The second correction amount calculating section calculates a second correction amount through multiplying a control gain corresponding to the vehicle speed with a value calculated by low-pass filtering a differential value of steering wheel angle. The motor rotational angle calculating section calculates a motor rotational angle corresponding to the value adding the first and second steering angle correction amount, and outputs it to a motor driving section so as to drive an electric motor for correcting the steering angle. Thereby, an unstable vehicle behavior due to a resonance of a yaw motion caused in the steering operation can be suppressed.

摘要： An estimated value of wakefulness is calculated from the ratio between the quantity of high frequency components and the quantity of low frequency components obtained by performing frequency transformation of vehicle displacements (S51). An imaginary deviation line is set between a lane marking and the vehicle according to the estimated value of wakefulness (S55, S59, S62, S66), and an alarm is issued when the vehicle deviates from the imaginary deviation line. Since the alarm is issued when the vehicle is at a predetermined distance from the lane marking, alarming can be performed at substantially constant timing.
摘要翻译：从高频分量的数量与通过车辆位移的频率变换获得的低频分量之间的比率计算出觉醒的估计值（S51）。根据估计的觉醒值（S55，S59，S62，S66），在车道标记和车辆之间设置假想偏离线，并且当车辆偏离假想偏离线时发出报警。由于当车辆距离车道标记处于预定距离时发出报警，所以可以以基本恒定的时间进行报警。

摘要： An image forming apparatus of the present invention includes a bias power supply for applying a bias VB to a developer carrier on which a developer is deposited. A charge potential deposited on an image carrier, which faces the developer carrier for forming a latent image thereon, is 400 V or below in absolute value. Assume that the potential of the image carrier is lowered to VL after exposure, that a development potential is |VB−VL|, that the maximum set value of the development potential for development is |VB−VL|max, and that the development potential varies in a range satisfying relations: |VB−VL|≦|VB−VL|max+|VB−VL|max×0.2 |VB−VL|≧|VB−VL|max−|VB−VL|max×0.2 |VB−VL|max≦300 V Then image density varies by a width of 10% of image density corresponding to the maximum set value of the development potential or less.

摘要： A developing device of the type developing a latent image formed on an image carrier with a two-ingredient type developer, i.e., a mixture of toner and magnetic carrier particles is disclosed. The device is operable without a sophisticated toner content control mechanism or a sophisticated developer agitating and conveying mechanism, and is capable of obviating various problems ascribable to the increase in the toner content of the developer at the opposite end portions of a developer carrier. For this purpose, the device restricts the movement of a developer present on the developer carrier in the direction substantially perpendicular to the direction in which the developer carrier conveys the developer.

摘要： A developing device for an image forming apparatus and capable of automatically controlling the toner content of a developer is disclosed. Even when the toner content of the developer deposited on a developer carrier and being conveyed toward a developing position becomes irregular due to some cause, the developer is prevented from remaining at the developing position. This guarantees a desired developing position despite the automatic toner content control. In addition, the toner content of the developer is prevented from increasing at portions adjoining the opposite ends of the developer carrier.

摘要： A developing device for an image forming apparatus and of the type using a developer consisting of toner and magnetic particles is disclosed. While a developing sleeve conveys the developer deposited thereon, toner is automatically replenished to the developer from a toner hopper via an opening formed in the hopper due to the movement of the developer. At the same time, the toner introduced into the developer is charged by friction. A developer storing member includes a penthouse portion. A projection protrudes from the surface of the penthouse portion facing the developing sleeve toward the sleeve and extends in the direction perpendicular to the direction in which the sleeve conveys the developer. The developer forms on the sleeve a layer having stable toner content and stable toner charge without resorting to a sophisticated toner content control mechanism.

摘要： In an image forming apparatus, a toner concentration sensor senses the concentration of a toner contained in a developer which is stored in a developing unit. A toner concentration controller controls a toner replenishing member in response to the output of the toner concentration sensor, thereby replenishing the toner from a toner container to the developing unit. Despite that a single toner concentration sensor is located in a position relatively close to a replenishing position, the apparatus insures stable image quality by effecting toner concentration control in harmony with the balance of toner in the entire developing unit.
