摘要： The present invention is a substrate for use in a display panel. According to the substrate, lines (102, 106, 107, and 113) provided in a display region on the substrate are made up of multiple layers whose uppermost layers (102c, 106c, 107c, and 113c) are each made from (i) an oxide of first metal selected from the group consisting of copper, titanium, and molybdenum or (ii) a nitride of copper. This can prevent external light from being reflected and thereby improve a contrast in a bright room.

摘要： An electric power steering apparatus including a steering angle detection part that detects a steering angle of a steering wheel and outputs a steering angle signal, a steering control unit that controls a motor to give an assist torque to the steering wheel, an abnormality detection part that determines an abnormality of the steering angle detection part, and a motor angle detection part that detects a rotational angle of the motor. The steering control unit calculates a steering angle information based on at least the steering angle signal, and includes a signal storage part that stores the steering angle information. The steering control unit runs the motor continuously when the abnormality detection part detects the abnormality of the steering angle detection part until a vehicle stops or until the abnormality detection part determines that the steering angle signal returns to a normal state from the occurrence of the abnormality.

摘要： It is an object of the present invention to provide a control unit for an electric power steering apparatus for accurately detecting an abnormality of a steering angle sensor without forming the steering angle sensor as a double system or using an expensive position detection sensor. The object is achieved by calculating a relative steering angle by using inexpensive position detection sensors disposed at a motor of the electric power steering apparatus to output binary values and comparing a change amount of an absolute steering angle detected by the steering angle sensor and a change amount of the calculated relative steering angle with each other to thereby detect the abnormality of the steering angle sensor.

摘要： A storage medium (magnetic disk) in a storage device (magnetic disk device) includes a disk that stores therein data, a head that reads and writes data, a voice motor coil (VCM) that controls the head, and a ramp where the head is retracted. The storage device detects a current used for speed control during unloading of the head, and determines whether the current exceeds a predetermined value. The storage device detects a head position where the current exceeds a predetermined value as a ramp position, stores the ramp position, and unloads the head based on the ramp position.

摘要： A falling-time measuring unit measures time for which a fall of a storage device is consecutively detected by a fall detecting sensor. A head-position detecting unit detects a position of the head on a storage medium at a time of starting measuring the time. A moving-time calculating unit calculates necessary time for moving the head from the detected position to a destination position. A first-threshold determining unit determines whether the measured time exceeds a threshold calculated by a threshold calculating unit. A head-movement processing unit moves the head to the destination position when it is determined that the measured time exceeds the first threshold.
