摘要： PROBLEM TO BE SOLVED: To stably optimize shift proceeding speed at the beginning of inertia phase depending on rotational difference between rotation of a turbine before the gear shift and that of after the gear shift in drive down shift without feedback control, by providing a hydraulic control means on releasing side. SOLUTION: In hydraulic control on releasing side of drive down shift, control is carried out to processed with gear shift at the beginning of inertia phase whole keeping oil pressure which is obtained by subtracting control requirement differential pressure PR3 from oil pressure at a time of starting inertia phase. Thereby, without feedback control which giving rise to a problem of unstable control caused by request for high detection accuracy or delay of response, proceeding speed of gear shift at the beginning of the inertia phase is stably optimized depending on rotational difference NTDIF between rotation of a turbine before the gear shift and that of after the gear shift. That is, at a low speed where the rotational difference NTDIF of the turbine is small, there is prevented idling of an engine caused by missing preparation for start-up of the oil pressure on the releasing side. At high speed where the rotational difference NTDIF is large, the rotation of the turbine can be blown up.

摘要： PROBLEM TO BE SOLVED: To secure required rigidity without increasing an outside diameter concerning a planetary gear mechanism constituting a power train of an automatic transmission devised to doubly have a function as a clutch hub by forming a spline on an outer periphery of a ring part of an internal gear. SOLUTION: An internal gear 14c is constituted of a ring part 150 and a side plate 152. The ring part 150 functions as a clutch hub, and an internal tooth 150-1 to be engaged with a pinion 14b is formed on an inner periphery and a spline 150-2 to store a drive plate 22a is formed on an outer periphery. The spline 150-2 is formed by offsetting it in the axial direction from the internal tooth 150-1, and thickness of the ring part 150 on the internal tooth 150-1 ia made gradually larger against thickness of the ring part 150 on the spline 150-2 toward an internal gear opening end.

摘要： PROBLEM TO BE SOLVED: To improve an engine brake performance and prevent generation of undesired vibration of a car due to torque fluctuation by carrying out a braking control of a lock-up clutch based on a data representing a selection control region and a request signal from a control mode changing request operation part in a fixing setting mode. SOLUTION: A lock-up(L/U) clutch control condition determining part 14 represents a mode selection signal from a mode selection operation part 22 as a fixing setting mode, and further supplies a request signal from a L/U clutch control mode changing request operation part 26. Based on a data representing a selection control region stored in a memory part 16, determination whether or not a control condition of the L/U clutch is made or not is carried out, a determination output is fed, and an operation control part 12 carries out an control of the L/U clutch operation in response to the determination output from the L/U clutch control condition determining part 14, whereby the L/U clutch can be selectively controlled in response to the request signal. Accordingly, in the fixing setting mode, an undesired vibration of the car due to torque fluctuation can be avoided.

摘要： PROBLEM TO BE SOLVED: To reduce size and to prevent a lowering of durability of a friction plate, in the structure of coupling a hub member, such as a clutch, to a sun gear. SOLUTION: A hub member 116 and a sun gear 121 are intercoupled through a connecting shell 160. The teeth of the outer peripheral part of the connecting shell 160 are engaged with the inner peripheral surface spline, and the connecting shell 160 and the hub member 116 are integrally rotatable. A stopper protruded in a way that cuts formed in the spline 136 are squeezed is formed on the hub member 116, and the connecting shell 160 is nipped between the stopper and a snap ring and is axially positioned. Since there is no fear of a weld strain occurring, the engaging position in an axial direction of the connecting shell 160 is overlapped with friction plates 137 and 138. And meanwhile, even when a backlash occurs to a sun gear, inclination due thereto is prevented from transmission to the hub member.

摘要： PROBLEM TO BE SOLVED: To provide a portable position detector for enhancing a walker's position detecting accuracy by an autonomous navigation by more accurately detecting a walker's moving bearing even if reception of GPS signal is impossible (or without receiving the signal) and altering to a step meeting a walking state and a position managing system. SOLUTION: A moved position is detected by calculating 'number of steps ×step width' by using a portable position detector of the user, and corrected to a step meeting a walking state from a walking time per one step by using an acceleration sensor 23. A person's moving position is detected with good accuracy via an autonomous navigation by detecting a moving direction by using a geomagnetic sensor 13. Particularly, even in the case of positioning at a forest, a valley among buildings or the like capable of receiving no GPS satellite signal due to the presence of a multi-story building, a cliff, the forest or the like, the position of the person carrying the detector by the navigation applicable to a walker and portable size and weight can be known practically with sufficient accuracy while enhancing an accuracy of the step.

摘要： PROBLEM TO BE SOLVED: To prevent a disc spring housed in a case from wearing the case inner peripheral part when the disc spring is pressed. SOLUTION: Many driven plates 14 are fitted on the inner periphery of a clutch drum 12. Drive plates 16 are arranged between the driven plates 14, 14. The drive plates 16 are attached to a clutch hub 18. A piston 20 is so arranged as to face the driven plate 14a on the rightest end. A disc spring 22 is arranged between the driven plate 14a and the piston 20. The disc spring 22 is so arranged that the inside diameter side may be brought into contact with the driven plate 14a and that the outside diameter side may be brought into contact with the piston 20. A cylindrical supporting part 14a1 projecting outward from the inside diameter side of a ring-shaped plate main body is formed on the driven plate 14a to be brought into contact with the disc spring 22. The outside diameter size of the supporting part 14a1 corresponds to the inside diameter size of the disc spring 22, and the disc spring 22 is fitted to the supporting part 14a1 of the driven plate 14a.
