Abstract: A wheel speed detecting device for a vehicle having wheel speed detectors for detecting left and right wheel speeds, respectively; a turning state detector for detecting the turning state of the vehicle; and a correcting and calculating device for correcting the wheel speeds on the basis of an output from the turning state detector and for calculating a value representative of the left and right wheel speeds on the basis of the corrected wheel speeds. Thus, an error of wheel speeds detected during turning of the vehicle can be compensated for, thereby determining a correct wheel speed.

Abstract: An apparatus for controlling a DC motor connected to an intake throttle valve in an internal combustion engine to detect an actual opening degree of the intake throttle valve and to match the actual opening degree with a command opening degree. The apparatus includes a feedback loop for defining a feedback signal indicative of a command to converge the actual opening degree of the control member to the command opening degree by reception of the command opening degree delivered by a command opening degree generating means and the actual opening degree delivered by an actual opening degree detecting means, a combined-signal generating means for combining the feedback signal defined by the feedback loop with the command opening degree delivered by the command opening degree generating means, and a motor driving means for driving the DC motor in response to an output from the combined-signal generating means. Thus, it is possible to converge the actual opening degree of the intake throttle valve to the command opening degree with a good responsiveness and a good positioning accuracy.

Abstract: Erasable optical disk media basically comprise a double layer structure composed of a thermal expansion layer formed of an organic dye and a binder, and a retention layer of metal. In the recording process, the thermal expansion layer is heated to form a dome-like pit in the retention layer. The reproducing process is performed by reading differences in reflectivity from the pit and an area surrounding the pit. In the erasing process, the retention layer including the pit is heated to flatten the same under the tensile stress (residual stress) acting on the thermal expansion layer. The pit size is kept in a stable condition during the recording and reproducing processes, while the erasing can be performed completely without leaving partly erased traces. The erasable optical disk media of the foregoing construction are highly durable and resistant to heat.

Abstract: The valve lift characteristic of inlet and/or exhaust valves of an internal combustion engine is changed when an excessive slip state of at least one driving wheel of the vehicle is detected. Restoration of the changed valve lift characteristic is inhibited when a specific running condition of the vehicle is detected, or when turning of the vehicle is detected. According to other aspects of the invention, a predetermined valve lift characteristic-changing control manner is changed in response to a detected road surface condition, or in response to detected turning of the vehicle. According to another aspect of the invention, a feedback control amount is calculated based upon a difference between a detected driving wheel speed and a detected vehicle speed, and at least one predetermined gain. The output torque of the driving wheels is reduced in response to the calculated feedback control amount. The valve lift characteristic is changed when the calculated feedback control amount indicates an excessive slip state of the driving wheel(s), and the value of the gain is changed when the valve lift characteristic is changed.
