Abstract: PURPOSE:To prevent the occurrence of rapid vehicle behavior in a limit turning region by computing a deviation between a target behavior computing value and an actual behavior detecting value by means of the values, limiting a maximum limit amount of a four-wheel steering control system when the deviation exceeds a given value, and facilitating entrance to control of reduction of traction. CONSTITUTION:Actual behavior of vehicle produced by means of a yaw rate exerted on a vehicle, lateral acceleration, and a slip angle is detected by an actual behavior detecting means (a) and target behavior of a vehicle produced through steering is computed by a target behavior computing means (b). A deviation between the detected value and the computer value is computed by a deviation computing means (e) and the computed value is outputted to an integrated control means (f). When the deviation exceeds a given value, a command by means of which a maximum control amount of a four-wheel steering control system (c) is limited is outputted by the integrated control means (f), and a command by means of which entrance to control of reduction of traction is facilitated is outputted to a traction control system (d). This constitution achieves controllability and stability of vehicle behavior with high responsiveness.

Abstract: Hitherto, sulphur compounds have been removed from hydrocarbons by adsorption on activated carbon, silicates and zeolites. The use of a zeolite containing zinc and manganese is also known. However, all the existing processes are unsuitable for removing traces of sulphur from hydrocarbons. The novel process is thus intended to allow a deep desulphurisation of hydrocarbons. The deep desulphurisation of hydrocarbons is achieved by adsorption of the sulphur compounds on zeolites which contain copper, silver or zinc or mixtures thereof. Deep desulphurisation of hydrocarbons.

Abstract: A mobile station comprises a receiver for receiving a signal from the base station and a transmitter including a frequency synthesizer, a modulator and a power amplifier connected to it. For power savings purposes, the transmitter is deactivated during a standby mode. If an earlier portion of a signal received from the base station indicates a likelihood of a need to return an acknowledgment, power is supplied to the frequency synthesizer to allow it to stabilize in advance. If a later portion of the received signal indicates that there actually exists the need to acknowledge the receipt of the signal, the power amplifier is subsequently activated and an acknowledgment signal is returned through it to the base station. If the later portion of the received signal indicates the absence of the need to acknowledge, the frequency synthesizer is again deactivated and the power amplifier remains deactivated.

Abstract: PURPOSE:To effectively perform the self-recovery to a failure by use of a case in which recovering work is described. CONSTITUTION:Cases are hierarchically classified according to failure symptoms, failures and classes, and a case suitable to a caused failure is selected to perform recovering work. Application priorities are given to the classes, and when the applicable case is present in plural classes, the application priorities are referred to at need. When the application of the case is successful, the application priority of the class to which the case belongs is raised to make this class easy to apply. The application priority of the related class is also raised to properly cope with a failure occurring from the same cause. When the failure can not be recovered by the case application, the work is inferred by qualitative inference to recover the failure. When it is successful, the inferred work is registered as the case of a new class. When a plurality of cases to be applied belong to the same class, only one representative case is applied to raise the success ratio of case application.
