摘要:
Steering apparatus includes at least one motor for generating a steering assisting force in a direction to steer a steerable wheel, two drive circuits having respective switching elements for PWM-controlling the motor, and a controller for differentiating, between the drive circuits, a control frequency at which the switching element is switched on and off. The differentiated PWM switching timing can effectively reduce switching noise and magnetostrictive sound of the motor.

摘要:
A motor driving method for a steering apparatus for applying an auxiliary steering force to a steering system with two motors. When the two motors are driven, a first one of the two motors is operated first. Thereafter, the other, second motor is driven, whereby smooth steering is effected.
摘要:
In an ink tank, a main ink chamber is contiguous to a sub ink chamber containing an absorption member, and an air communication hole is formed on the top of the sub ink chamber. The absorption member holds ink pressure constant by capillary attraction of the absorption member. First, ink in the sub ink chamber is consumed with consumption of ink. When ink is consumed in a predetermined amount, air passes through the absorption member and a meniscus forming portion to form bubbles, which then move to the main ink chamber. Ink pressure is held constant by surface tension of the meniscus forming portion. Even if ink remains in a small amount, the ink leading portion makes the meniscus forming portion wet for holding ink pressure.
摘要:
A displacement detector for enabling a precise detection of a displaced quantity of the core. The displacement detector is provided with a displaceable core, a detecting coil the inductance of which varies in response to a displaced quantity and a reference resistor, wherein a transient response voltage in case of a pulse voltage being applied to the inductance and the reference resistor is detected to enable detection of the absolute value of the inductance and thereby the change in the inductance which corresponds to the displaced quantity is detected independently of the peak value or the frequency of the pulse voltage. The displacement detector is preferably used in a torque sensor for an electric powered steering system, wherein the core of the displacement detector is formed of nonmagnetic metal material, the structure is simple, and a sensitive detection of a displaced quantity of the steering torque is possible.
