  • Patent number: 8947021
    Abstract: An accelerator includes an inflector through which a beam entering from an ion source passes and which introduces the beam to an acceleration orbit. The inflector includes a beam convergence unit that converges the beam passing through the inflector. A cyclotron, which accelerates a beam in a convoluted acceleration orbit, includes magnetic poles, D-electrodes, and an inflector. The magnetic poles generate a magnetic field in a direction perpendicular to the acceleration orbit. The D-electrodes generate a potential difference, which accelerates the beam, in the acceleration orbit. A beam, which enters in an incident direction perpendicular to the acceleration orbit, passes through the inflector, and the inflector bends the beam so as to introduce the beam to the acceleration orbit. The inflector includes a beam convergence unit that converges the beam passing through the inflector.

  • Patent number: 8935062
    Abstract: 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.

  • Patent number: 8880310
    Abstract: If it is determined that a D range is in use and determined that a vehicle is stopped, neutral control means (25) commands and controls an engagement pressure of a clutch (C-1) so as to achieve a state in which a piston of the clutch (C-1) contacts a clutch drum by a biasing force of a spring, and a state in which oil fills an oil passage from a linear solenoid valve (SLC1) to a hydraulic oil chamber and fills the hydraulic oil chamber. There is thus no drag loss in the clutch (C-1) during a neutral control, and the same fuel economy as when, for example, a manual shift to the neutral range is made can be achieved during the neutral control.

  • Patent number: 8678977
    Abstract: A control device for controlling a transmission device configured such that when the speed change mechanism performs switching to a shift speed with a different speed ratio, special speed change control is executed in which a disengagement hydraulic pressure, is lowered to cause a disengagement element to slip, and in which the disengagement element is maintained in a slipping state over an entire speed change process. In the case where slipping of the disengagement element is not detected within a predetermined time after the disengagement hydraulic pressure is lowered at start of the special speed change control, pressure increase correction is performed in which an engagement hydraulic pressure, which is a hydraulic pressure of hydraulic oil for an engagement element that is a friction engagement element to be engaged, is raised until slipping of the disengagement element is detected.
