20090278362 | CYCLOCONVERTER GENERATOR - In a cycloconverter generator, AC power required by the load is detected and a desired speed of the engine is determined based on the required AC power, operation of an actuator is controlled such that the engine speed becomes equal to the desired engine speed, and the required AC power is generated by turning on switching elements (thyristors) such that a number of the phase signal within one period of frequency of the AC power, becomes equal to a number determined by the desired engine speed, thereby preventing undesirable increase in fuel consumption and noise by operating the engine at a speed corresponding to required AC power and enabling to generate stable AC power even when the engine speed changes abruptly. | 11-12-2009 |

20130025389 | CONTROL APPARATUS FOR AUTOMATIC TRANSMISSION - In a control apparatus for an automatic transmission having multiple speeds constituted by four sets and speed selecting mechanisms corresponding to the four sets, assuming the speeds as seven among eight speeds of A to H in order of gear ratio, the four sets are constituted by a first set of A having a largest gear ratio and C that is next but one; a second set including at least H having a smallest gear ratio; a third set of B and D between two of the first set; and a fourth set including two of E, F and G between the second and third sets, and one of first and second pressure regulators selectively supplies hydraulic pressure to two of the mechanisms corresponding to the first and second sets, while the other thereof selectively supplies hydraulic pressure to two of the mechanisms corresponding to the third and fourth sets. | 01-31-2013 |
20150184742 | SHIFT CONTROL DEVICE FOR AUTOMATIC TRANSMISSION - Adding a driver's intention and running environments to conditions for cancelling a delay of an upshift after kickdown enables the upshift at a suitable timing depending on a vehicle's running environments and aspects of the driver's operation. A shift control device for automatic transmission calculates an allowance driving force of the vehicle when upshifting at a current vehicle speed and throttle opening, and also calculates a threshold value of a driving force depending on an average value of throttle opening variation, an average value of vehicle speed variation, a cornering judgment of a winding degree of a road on which the vehicle is running and a gradient judgment of a gradient of a road surface on which the vehicle is running. Then, after comparing the threshold value and the allowance driving force, the device permits an upshift when the allowance driving force is larger than the threshold value. | 07-02-2015 |

20110019945 | BAG CONTAINER - A bag container includes a synthetic-resin container body shaped by using a mold and including a body portion including a bottom portion and a spout-forming portion. A spout is formed by tearing an easy-to-tear portion of the spout-forming portion and removing a to-be-torn-off portion. The spout-forming portion is provided projecting upward, perpendicular to a placing surface formed by the bottom portion, from the body portion. An opening tab piece including an engagement hole with which the ball of a finger is to engage is provided projecting on one side of the spout-forming portion. The engagement hole has a shape that guides the finger such that, when the easy-to-tear portion is to be torn, the ball of the finger engages with a circumferential edge portion of the engagement hole from the inner side thereof while being oriented toward the circumferential direction centering about an end of the easy-to-tear portion. | 01-27-2011 |
20110026859 | BAG CONTAINER - A bag container including a synthetic-resin container body shaped by using a mold and including a spout-forming portion and a filling inlet portion that project outward therefrom. Contents are first filled through the filling inlet portion, and then fusion-bond sealing is applied to the filling inlet portion. The filling inlet portion has, at its sealing base portion, a square cross-sectional shape. A tip-end-side cross-section-changing portion and a cylindrical portion are provided on the tip-end side with respect to the sealing base portion. Four triangular panels each isosceles triangle shaped are connectedly provided on the side of the container body with respect to the sealing base portion along a circumferential direction of the filling inlet portion, a base of each isosceles triangle formed of one of sides of the square cross-sectional shape. When the fusion-bond sealing is to be applied to the filling inlet portion, a region on the tip-end side with respect to the sealing base portion is folded flat while positioning a pair of opposing corners on opposite edges of the filling inlet portion. | 02-03-2011 |
