摘要:
A control apparatus for an electric power steering system is provided, which controls a motor for applying assist steering torque to a steering line of a vehicle at least according to steering torque signal of the steering line, vehicle velocity signal and motor current signal. The control apparatus includes a target current controller (21) for setting target current signal for driving the motor, a deviation calculator (22) for computing a deviation between the target current and motor current signals, a deviation adjuster (23) for adjusting the deviation with a variable gain according to the vehicle velocity signal, a proportional element (24a) for executing proportional control for the motor, an integral element (24b) for executing integral control for the motor and a gain adjuster for adjusting the gain according to a differential of the steering torque signal.

A method of manufacturing a fluidic angular rate sensor of the type that fine wires such as tungsten wires are tensely spread over the heads of two pairs of metal supports which are mounted on a ceramic disc having fluid passage apertures, includes the steps of: plating a gold on the wires and fixedly spreading the wires over the metal supports by means of thermocompression bonding or the like; and heating the wires in a predetermined atmosphere which allows the plated gold to be removed and the wires to be crystalized.

摘要:
This device provides an electric signal linearly dependent on the oxygen content of a gas without the need of a reference gas; it is constituted by a solid electrolyte substrate (3) coated with two separate electrodes (1,2) connected to the terminals of an electric voltage source. In the presence of a gas of which the content of oxygen must be measured and when a given voltage is applied between the two electrodes (1,2), oxygen molecules are ionized in the region of the electrolyte close to the cathode (1). The current which flows between the two electrodes (1,2) consitutes the measuring electric signal provided by the sensor.
