  • Patent number: 9874278
    Abstract: A control device for an automatic transmission disposed in a vehicle driving system, the automatic transmission having an engaging clutch as shift element, has a shift controller that performs a shift control of the automatic transmission. The shift controller is configured such that, during a shift control to release the engaging clutch in response to a first shift request and after determination of a releasing start of the engaging clutch, when a second shift request to engage the engaging cutch is generated, the shift control in response to the first shift request will be continued.

  • Patent number: 9593767
    Abstract: A shift control device for an electrically driven vehicle, which is installed in the electrically driven vehicle including a motor as a drive source and an automatic transmission coupled to an output shaft of the motor, has a shift controller that performs shifting of the automatic transmission using a previously set shift line. The shift controller has, as the shift line, an electricity consumption prioritized shift line with priority placed to improve electricity consumption rate, and a driving force prioritized shift line with priority placed to suppress the frequency of shifting. The driving force prioritized shift line is used for a predetermined time after completion of the shift control using the electricity consumption prioritized shift line.

  • Patent number: 9346372
    Abstract: A gear shifting control device is provided with a driving motor-generator, an automatic transmission provided in a drivetrain and a gear shifting controller. The automatic transmission has a P range, an N range and a D range as selectable range positions. The gear shifting controller changes the gears in the automatic transmission. The gear shifting controller sets the N range of the automatic transmission to be a range over which the driving motor-generator is not caused to generate torque even when a operation for depressing an accelerator pedal has been performed, and places a coupling clutch in an engaged state in first gear when the N range is selected.

  • Publication number: 20100228099
    Abstract: The present invention provides a device for predicting prognosis of a patient who undergoes PEG, which allows a doctor to obtain predictive results sufficient to judge whether or not to perform the PEG (percutaneous endoscopic gastrostomy) for the patient. This device includes: a prognosis prediction expression storage section 14 configured to store a prognosis prediction expression, the prognosis prediction expression being calculated by applying prediction input factors and prediction output factors about a first patient who already underwent the PEG, to ANN (artificial neural network); and a processing section 16 configured to: receive diagnosis input factors about a second patient, for judging whether or not to perform the PEG on the second patient; calculate diagnosis output factors in response to the diagnosis input factors based on the prognosis prediction expression; and output the calculated diagnosis output factors.

  • Patent number: 7204783
    Abstract: When, with engine kept stopped, driven road wheels are turned, the toroidal type continuously variable transmission is suppressed from shifting toward a higher speed side. That is, when, with the engine kept stopped, the road wheels are turned in a reverse direction due to a traction of a motor vehicle with its front end facing backward, an extra oil pump driven by the road wheels produces an oil pressure which is applied to a hydraulic servo mechanism to keep a speed change ratio at a lower speed side. While, when, with the engine kept stopped, the road wheels are turned in a forward direction due to a traction of the motor vehicle with its front end facing forward, the oil pressure produced by the extra oil pump is not practically used. Under this condition, a biasing spring suppresses a servo piston from moving in a direction to bring about a speed change ratio for the higher speed side.

  • Patent number: 7192380
    Abstract: In a toroidal continuously variable transmission, a primary oil pump is driven by an engine, whereas a secondary oil pump is driven in response to rotation of a road wheel. A hydraulic servo mechanism is connected to a trunnion to create an offset of the trunnion from a neutral position for a tilting motion of the power roller. Also provided is a hydraulic system that supplies the hydraulic pressure discharged from the secondary pump to the hydraulic servo mechanism to prevent the offset of the trunnion in the trunnion-axis direction, corresponding to an upshift, occurring owing to rotation of the road wheel in a stopped state of the engine. A modulated hydraulic pressure, which is constantly produced by the hydraulic system during operation of the engine, acts to hold the secondary pump at either of an inoperative state and an unloaded condition during the operation of the engine.

  • Patent number: 6647606
    Abstract: In an assembly of a toroidal continuously variable transmission, a sheath member (41) is temporarily fitted on a male screw (3A) so that a step between a spline part (21A) and a male screw (3A) of a CVT shaft (3) does not catch on an output disk (18, 20) when the CVT shaft (3) is passed through the output disk (18, 20). The outer diameter of the sheath member (41) is gradually reduced in a tapering shape from an outer diameter equal to that of the spline part (21A).

  • Patent number: 6527666
    Abstract: A toroidal type continuously variable transmission includes trunnions (4) formed with shoulder portions (40) which oppose an upper link (5) and a lower link (6), and projections (50) on the links (5, 6) which can slide on the shoulder portions (40) when the links (5, 6) perform swinging movement. Along with forming the trunnions (4) in single units by forging, step portions (4B) are arranged between the shoulder portions (40) and sloping portions (45) of the offset portions (4A). Planar portions (40A) are formed in the shoulder portions (40) which can slide on the projections (50) by cutting or grinding so that their radiuses R from the rotation axes (4C) up to the end portions of the step portions (4B) are set in advance.

  • Patent number: 6498007
    Abstract: The invention relates to a method for the removal of leucocytes from blood which comprises bringing blood that comprises infected leucocytes into contact with an adsorbent carrier that has a greater affinity for infected, activated and/or defective leucocytes than for uninfected leucocytes especially cellulose acetate. The method can be used in the apheresis treatment of diseases caused by pathogenic organisms, for example, HIV, HCV or malaria. It is especially useful for treatment of HIV.

  • Patent number: 6413187
    Abstract: In a toroidal type continuously variable transmission, shoulder portions are formed on a trunnion which opposes an upper link or a lower link, and projecting portions are formed on the links which slidably contact the shoulder portions when the links execute swinging movement. The end portions of the projecting portions which slidably contact the shoulder portions are formed with arcuate faces.

  • Patent number: 6390946
    Abstract: Even in the case where a driver switches a select lever from D range to N range and returns it back to D range during the running of a vehicle, a speed change control device prevents the operation of sudden speed change caused by a difference between a transmission input rotational speed and the actual input rotating speed of a toroidal transmission unit while in the N range. Accordingly, an automatic transmission comprises a forward-reverse switching mechanism, an impelling mechanism and a toroidal transmission unit which are sequentially arranged from the driving source side of a vehicle, and further comprises a speed change control device for controlling the operation of the above.
