20140038002 | FILM-COVERED BATTERY AND ASSEMBLED BATTERY - The invention provides a closed type battery comprising a battery element covered with a covering film and a heat fusion seal portion formed by heat fusion on a periphery of the covering film, wherein the cleaving strength upon an internal pressure rise of a seal portion positioned between a positive electrode terminal and a negative electrode terminal is larger than that of any other seal portion, and a safety valve adapted to release pressure upon a battery's internal pressure rise is located at a portion other than said inter-terminal seal portion. The invention also provides an assembled battery wherein a plurality of closed type batteries are stacked one upon another while a safety valve adapted to release pressure upon an increase in the internal pressure of the battery is located at a position in no contact with the covering film surface of an adjoining battery. | 02-06-2014 |

20130311072 | POWER-STEERING CONTROL SYSTEM - In a power-steering control system installed in a vehicle, a state determiner determines whether an engine is in a state in which the engine is stopped. A steering-torque detector measures steering torque applied to a steering wheel by a driver of the vehicle. A controller holds the power steering motor in a ready state to generate the assist torque if it is determined that the engine is in the stop state and that the measured steering torque is equal to or higher than first threshold torque. | 11-21-2013 |

20150291736 | METHOD FOR PRODUCING POLYAMIDE - The invention is a method for producing a polyamide having a melting point of 255° C. or higher through polycondensation of a mixed xylylenediamine containing paraxylylenediamine as a diamine component and a dicarboxylic acid component in a batch reactor, wherein when the diamine component is dropwise added to the dicarboxylic acid component kept in a melt state by heating it to a temperature not lower than a melting point thereof under a pressure of 0.1 MPaG or more with keeping the melt state of a reaction mixture, a temperature of the reaction mixture is maintained at 255° C. or lower until a molar ratio (diamine component/dicarboxylic acid component) of the reaction mixture reaches 0.8, and the temperature of the reaction mixture at the end of the dropwise addition is controlled to be not lower than the melting point of the polyamide. The method enables production of a polyamide having an improved hue and being advantageous with respect to quality. | 10-15-2015 |

20150073120 | PRODUCTION METHOD FOR POLYAMIDE - The present invention is directed to a process for producing a polyamide, which process includes directly melt-polymerizing a diamine component including 70 mol % or more of p-xylylenediamine and a dicarboxylic acid component including 70 mol % or more of a C6 to C18 aliphatic dicarboxylic acid, in the absence of solvent in a batch-type reactor equipped with a stirring blade, the process including: (1) reacting the diamine component with the dicarboxylic acid component under a pressure condition of 0.2 to 0.5 MPa (Abs); (2) maintaining a vapor phase section of a reaction tank of the reactor at 200° C. or higher during reaction; (3) stirring the contents of the reaction tank, from the start of adding the diamine component until after completion of the addition and before the start of pressure falling, such that the stirring-related Froude number represented by a specific formula is adjusted to 0.0002 to 0.15; and (4) employing a stirring blade having no structural body in the horizontal direction or having a structural body in the horizontal direction, which body does not come into contact with the interface between the reaction mixture and the vapor phase section during stirring. In the polyamide production process, deposition of solid matter in the reaction tank vapor section and in a vapor pipe is suppressed, and incorporation into the product of unmelted solid matter originating from the deposits is reduced. | 03-12-2015 |
20160039993 | XYLYLENEDIAMINE COMPOSITION, AND METHOD FOR PRODUCING POLYAMIDE RESIN - Provided are a xylylenediamine composition containing xylylenediamine and bis(methylbenzyl)amine, a content of the bis(methylbenzyl)amine being 0.0005 to 0.1 parts by mass based on 100 parts by mass of the xylylenediamine; and a method for producing a polyamide resin including the steps of introducing a diamine containing xylylenediamine, a dicarboxylic acid, and bis(methylbenzyl)amine in an amount of 0.0005 to 0.1 parts by mass based on 100 parts by mass of the xylylenediamine into a reaction system and performing a polycondensation reaction. | 02-11-2016 |
