    摘要: A system and method for controlling an automatic transmission in a vehicle drive train including an engine, the automatic transmission and a fluid coupling for transmitting the rotation of the engine to the transmission. The transmission includes a clutch applied when a forward running range is selected; a second one-way clutch which is applied, when the first clutch is applied, to establish a forward 1st speed; and a brake for locking the one-way clutch, when applied, to block the reverse rotation of the output shaft of the transmission. A first hydraulic servo receives a first oil pressure for applying the first clutch and a second hydraulic servo receives a second oil pressure for applying the brake. When a forward running range is selected, with the vehicle stopped, the engine idling and a foot brake engaged, the oil pressure of the first hydraulic servo is lowered from the oil pressure at the 1st speed whereas the oil pressure of the second hydraulic servo is raised to a modulated pressure. The modulated pressure is set to generate, against the reverse force on the vehicle facing up an incline, a resistance corresponding to the forward driving force generated when the engine is idling in 1st speed.

    摘要: An automatic transmission control system providing a neutral control state in which there is no slipping engagement of a first clutch which is engaged upon selection of a forward range and, as a result, the vehicle is not subjected to idling vibration. The fuel consumption reducing effect of the neutral control state is maintained and there is no heating and consequent deterioration of the friction material of the clutch. The control system includes a hydraulic servo for operation of the clutch, an input side speed sensor for detecting the input side speed of a fluid power coupling device connecting the transmission to the output of an engine, an output side speed sensor for detecting the output side speed of the fluid power coupling device, and a controller. The controller includes differential speed calculator, differential speed change detector, a pressure increasing device for increasing the hydraulic pressure of the hydraulic servo by a set pressure when the differential speed has not changed, and a pressure reducing device for reducing the hydraulic pressure of the hydraulic servo by a set pressure when the differential speed has changed.

    摘要: A radiation quantum-counting method and apparatus for producing high resolution radiographic images capable of discriminating soft tissue cancer having a lcm size. The high resolution image is generated by a plurality of radiation sensitive elements, each element including a semiconductor material having a pair of electrodes mounted on opposite faces thereof. Each element is highly sensitive and produces a rapid pulse count since the thickness of the semiconductor material is substantially 0.1-0.5 mm, and the semiconductor material has an effective atomic number greater than 30 and an energy band gap greater than 1.3 eV. As a plurality of radiation quanta emanate from the radiation source, they are received by the plurality of radiation sensitive elements which detect individual radiation quantum and produce a pulse signal for each detected quantum. Coupled to each radiation sensitive element is a pulse amplifier for amplifying the pulse signals. The amplified pulse signals are counted and used to produce radiographic image signals containing details of image gradation. The pulse count may also be stored in a memory and used to provide two-dimensional information when combined with other pulse count data derived when the spatial orientation between the objective body and the radiation source is changed.

    摘要: 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.

    摘要: A control device controlling a vehicle's automatic transmission. The automatic transmission engages first and second friction engagement elements by fluid pressure from a pump operating using motive power from the vehicle's motor when a shift position is at a reverse traveling position, places the first friction engagement element on standby at a predetermined pressure that is higher than a stroke starting pressure by which a piston stroke is started and lower than a complete engagement pressure or engages the first friction engagement at the complete engagement pressure when the shift position is at a non-traveling position, and engages a third friction engagement element as a starting shift speed when the shift position is at a forward traveling position. When the shift position is at the forward traveling position, the first friction engagement element is placed on standby at the predetermined pressure if a vehicle speed is lower than a predetermined vehicle speed, or releases the predetermined standby pressure if the vehicle speed is equal to or higher than the predetermined vehicle speed.

    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.
