摘要： A magnetic head device incorporated in magnetic recording and playback equipment for recording and reproducing information from a magnetic disk. The device has a magnetic head which is formed with a plurality of grooves in the surface thereof that is to face a magnetic disk. The grooves reduce the friction acting between the head and the disk during operation and thereby allows the head to slide on the disk stably with a minimum of spacing loss.

摘要： A vehicle transmission device includes an input member coupled to a combustion engine and a rotary electric machine; an output member coupled to wheels; a speed change mechanism with a plurality of friction engagement elements and that provides a plurality of shift speeds; and a control device that controls the speed change mechanism. When a during-regeneration downshift is performed while the rotary electric machine is outputting regenerative torque, the control device sets a target increase capacity, which is a target value of a transfer torque capacity of an engagement-side element to be engaged after an increase, increases the transfer torque capacity of the engagement-side element to the target increase capacity over a predetermined torque capacity increase period, and decreases a transfer torque capacity of a disengagement-side element, which is to be disengaged, over a predetermined torque capacity decrease period that at least partially overlaps the torque capacity increase period.

摘要： A vehicle driving apparatus configured with a drive power source, a fluid coupling, a transmission apparatus; and a control apparatus. A rotation of a drive input member driven by the drive power source is transmitted to a shift input member via the fluid coupling and a rotation of the shift input member is shifted by the transmission apparatus and then transmitted to an output member. When a state shift command for shifting from a non-transmission state to a transmission state is input into a control apparatus in a state in which the drive power source does not generate a driving force, the control apparatus performs a shift input rotation operation before engaging a frictional engagement element and shifting to the transmission state by causing the drive power source to generate the driving force and rotating the shift input member via the fluid coupling while maintaining the non-transmission state.

摘要： A device with a stepped automatic transmission to transfer power from a power source to an axle using changeable shift speeds includes an input-side fluid transmission element connected to the power source, an output-side fluid transmission element connected to the transmission input shaft, a lock-up clutch engaging and disengaging the input-side and the output-side fluid transmission elements; a unit adjusting the lock-up clutch; a unit setting, when a downshift is to be performed in response to a predetermined request for a large drive force, a predetermined target slip speed value larger than a non-shifting-time value before a rotational speed of the power source exceeds a input shaft rotational speed after the downshift, and setting the target slip speed to decrease toward the non-shifting-time value along with lapse of time after the power source rotational speed source exceeds the post-shifting input shaft speed; and a unit controlling the engagement force so the slip speed becomes the set target slip speed. The target slip speed is a difference between the rotational speeds of the power source and the input shaft, and the non-shifting-time value is set when no shifting is performed.

摘要： A control system for an automatic transmission is provided with a manual shift mode capable of performing a shift command made by manual operation. While in the manual shift mode and during the operation of a downshift command generated by a shift lever, a manual shift control unit calculates a degree of power required by a driver that, for example, takes into consideration an operation intent of the driver and a road condition. A post-downshift shift speed is then determined in accordance with the degree of required power and downshifting performed. By performing only one downshift command through manual operation, downshifting in accordance with the degree of power required by the driver is performed. Downshifting to a shift speed desired by the driver can thus be promptly performed, without the operation becoming a burden.
