    摘要： (Meth)acrylic acid is reacted with a fatty acid anhydride and the resultant reaction mixture is neutralized and washed with an aqueous alkaline solution having a pH of 7.5 to 13.5. Thus, high-purity (meth)acrylic anhydride can be industrially advantageously produced while avoiding polymerization. This (meth)acrylic anhydride is reacted with a secondary or tertiary alcohol in the presence of a basic compound which in 25° C. water has an acidity (pKa) of 11 or lower. Thus, a high-purity (meth)acrylic ester can be produced in high yield.

    摘要： In an antiskid control system, the acceleration of a vehicle wheel is detected and compared with a predetermined value. A first count value is incremented in response to the detection of the wheel acceleration exceeding the predetermined value. When this first count value exceeds a reference count within a first preset period, the road is interpreted as having a rough surface and a second count value is similarly incremented in response to the detection of the wheel acceleration exceeding the predetermined count. If the second count value does not reach the reference count within a second preset period longer than the first preset period, the road is interpreted as having a smooth surface. The gradient of brake hydraulic pressure of the vehicle is controlled in response to the different interpretation of the road surface.

    摘要： In an antiskid control system for the hydraulic braking system of a wheeled vehicle, the rotational speed of a vehicle wheel and the acceleration of the wheel are detected and levels of road surface friction are determined on the basis of the wheel speed and acceleration to give a first indication that the road has a high value of friction or a second indication that the road has a low value of friction. The wheel speed and acceleration are analyzed to detect a down-pressure mode to decrease the fluid pressure of the braking system and an up-pressure mode to increase the pressure. In response to the presence of the first indication, the down-pressure mode is effected at a lower rate and then at a higher rate. In response to the occurrence of the second indication, the down-pressure mode is effected at the higher rate.

    摘要： An apparatus for detecting a disconnection of a sensor by monitoring a signal in a signal-carrying line for receiving an output signal of the sensor through a connector. The apparatus includes a feeder circuit for causing a current to flow through the connector to the sensor for a predetermined time period in the absence of the output signal of the sensor. The current flow causes elimination of an oxide film produced in the connector with time, resulting in the prevention of attenuation of the output signal due to the oxide film and in ensuring accurate detection of the disconnection of the sensor irrespective of secular change.

    摘要： A shock absorber control system for controlling the damping force of a variable shock absorber comprises a speed sensor for generating a signal indicative of the wheel speed of at least one wheel of the vehicle and a control unit for controlling the damping force. The control unit derives the acceleration from the wheel speed signal and compares the derived acceleration with upper and lower references. The damping force control is effected when the acceleration varies successively so as to assume both values outside the range between the upper and lower references.

    摘要： A pulse signal is generated by a wheel speed sensor with a frequency proportional to the speed of rotation of a vehicle wheel, the pulse signal comprising a plurality of frames each having a series of a predetermined number of pulses which are tended to be affected by noise and pulse mutilation. Pulses in each frame are counted and from the count is derived an instantaneous wheel speed value. The difference between the successively derived instantaneous speed values is taken and compared with a predetermined threshold. A first or a second indication is given in response to the difference being lower or higher than the threshold, respectively. If the first indication is given, output signals representing the average wheel speed and average wheel acceleration of the wheel are derived from the instantaneous speed values of successive frames. If the second indication is given, the instantaneous speed value of the previous frame is used instead of the instantaneous value of the subsequent frame which is disturbed by noise or pulse mutilation to derive the output signals.
