Abstract: In a disk device, in a state where no access to the disk is permitted, instead of permitting the head to be driven stepwise whenever step pulses are fed in, the head is inhibited from being driven stepwise until a predetermined period of time elapses after the disk starts being rotated. This helps reduce electric power consumption in such a state. Moreover, when the head has been retracted to its initial position because of an error in the stepwise driving thereof, instead of waiting for step pulses to be fed in from the host and thereby losing much time before the head is moved back to the track at which it was located before the error, the position of the head before the error is stored so that the head can be, by self recovery, moved back to the position before the error without waiting for an instruction from outside the disk device.

Abstract: A reverse input blocking clutch comprises, as main elements, an input member, an output member, a stationary member for constraining the revolutions, locking device, lock release device and torque transmission device. By forming the input member, the output member, the stationary member and a fixed side plate from metal plates such as press worked steel plates, a compact, lightweight and low cost reverse input blocking clutch is provided. Reverse input torque from the output member is locked in both the forward and reverse rotational directions relative to the stationary member, by rollers which function as the locking device. Input torque from the input member in both the forward and reverse rotational directions is transmitted to the output member via apertures 1d and protrusions which function as the torque transmission device.

Abstract: A transmission comprises an engine, which is controllable to stop under a predetermined condition, and a speed change mechanism TM, which transmits the output rotation of the engine at different speed ratios. The speed change mechanism TM has a plurality of transmission paths (the LOW ratio, the SECOND speed ratio, etc.) disposed in parallel, a plurality of ratio-setting clutches (the LOW clutch 11, the SECOND speed clutch 12, etc.), each clutch for selecting a predetermined transmission path, and a speed change control system for selectively supplying a hydraulic pressure to any of the ratio-setting clutches to bring it into engagement. Engagement-initiation time is calculated for each ratio-setting clutch, so that the ratio-setting clutch requiring a minimum engagement-initiation time is selected as the clutch for the start-up speed ratio. When the engine is restarted from stopped state, this clutch for the start-up speed ratio is supplied with oil.

Abstract: A firing or ignition state discrimination system for an internal combustion engines having a spark plug which produces spark discharge when supplied with discharge current from an ignition coil to ignite air-fuel mixture in the combustion chamber. In the system, ionic-current that flows during combustion of the air-fuel mixture is detected at a predetermined first timing and leakage current that flows across electrodes of the spark plug is detected at a predetermined second timing which is later than the predetermined first timing. The firing or ignition state of the engine is discriminated to one from among normal, misfiring, spark plug fouling, and failure in ignition system or in fuel supply system based on the detected ionic-current and leakage current and presence or absence of fuel cutoff to the engine. With this, it becomes possible to accurately discriminates the firing or ignition state of the spark plug and to inform the fact to the vehicle operator if desired.

The above failure may also be diagnosed according to at least one of the ignition timing and the engine rotational speed when decreasing the intake air amount during the execution of the catalyst temperature rise acceleration control. The above failure may also be diagnosed according to a detected catalyst temperature and an estimated catalyst temperature.

Abstract: Whether a driver is driving intentionally is determined rapidly and accurately when steering control is performed such that a vehicle travels along recognized travel partitioning lines. A torque value deviation absolute value is calculated using the absolute value of a difference between the torque value from the previous processing and the torque value from the current processing, and is stored in a ring buffer. A torque value deviation sum value is calculated by adding all the torque value deviation absolute values stored in the ring buffer, and when a state in which the torque value deviation sum value is equal to or less than a predetermined driving intention determination threshold continues for a predetermined first threshold time (for example, several seconds; e.g. 5 seconds) or longer, it is determined that there is a decrease in the driving intention.
