  • Publication number: 20130341892
    Abstract: A gas generator includes an inflator and a retainer. The retainer includes a holding portion, which partially covers the inflator. The inflator has an attaching protrusion for determining the position relative to the retainer. The retainer includes an engagement base and a tongue piece. The tongue piece extends in an axial direction of the inflator and from a position separated from the engagement base in the circumferential direction of the holding portion. The engagement base and the tongue piece each have an engagement portion. The engagement portions face each other to form an engagement space therebetween, into which the attaching protrusion enters. The engagement space has an inlet the width of which is less than the size of the positioning protrusion. When the inflator causes the positioning protrusion to increase the width of the inlet, the tongue piece is elastically deformed about a basal end of the tongue piece.

  • Patent number: 8573253
    Abstract: There is disclosed a valve assembly for a gas container capable of appropriately discharging a gas from the gas container, even if a valve of a discharge passage has a failure or the like. The valve assembly for the gas container disposed at the gas container has, as passages which allow the inside of the gas container to communicate with the outside, a filling passage which fills the gas container with the gas and a discharge passage which discharges the gas. Furthermore, the valve assembly has a filling-side valve disposed at the filling passage and configured to close this passage, a discharge-side valve disposed at the discharge passage and configured to close this passage, a communication path which connects a downstream side of the discharge-side valve to a downstream side of the filling-side valve, and a shut-off valve disposed at the communication path.

  • Patent number: 8555615
    Abstract: In a control method of an internal combustion engine exhaust gas control system which is applied to a hybrid vehicle that is powered by an internal combustion engine and an electric motor, an exhaust throttle valve, provided downstream of an exhaust gas control catalyst, is controlled to reduce its opening amount to a target opening amount when it is determined that warm-up control of the internal combustion engine needs to be executed. Next, a target injection quantity of fuel necessary to increase the temperature of exhaust gas flowing into the internal combustion engine to a target exhaust gas temperature is calculated. Then, assist torque from the electric motor is adjusted so that the sum of torque from the internal combustion engine when the fuel injection quantity has been set to the target injection quantity and the assist torque substantially equals a required torque.

  • Patent number: 8401909
    Abstract: A content distribution system which assures reliability of content is provided. Permitted-user information corresponding to a user who is permitted to use content to be distributed is associated with the content. In the case where user specific information which specifies a user and the permitted-user information do not have a predetermined relation, a user terminal transmits the user specific information and the permitted-user information to a server. The server generates user-related information in which the received user specific information is set as a distribution destination and the permitted-user information is set as a distributor, generates new permitted-user information so as to have the predetermined relation with the user specific information, and provides the new permitted-user information to the user terminal. The user terminal which obtains the new permitted-user information changes the permitted-user information to the new permitted-user information.

  • Patent number: 8390258
    Abstract: Upon detecting an external signal which instructs to stop discharge, an input voltage equal to or less than a set value for the prevention of overdischarge, or an output voltage equal to or more than a set value for the prevention of output of an overvoltage, a control unit (12) stops discharge to a load (40) by opening a switching element (4b) of a step-down unit (11b). Upon detecting that an external signal is reset or an input voltage equal to or more than a set value larger than the set value for the prevention of overdischarge, the control unit (12) resumes discharge to the load (40) by setting the switching element (4b) in a switching operation state or short-circuiting it.

  • Patent number: 8291697
    Abstract: An internal combustion engine control device includes a NOx adsorber catalyst disposed in an exhaust passage, an EGR passage, a reducing agent adding device, a torque fluctuation reducing device, and a fuel injection device. The EGR passage draws a portion of exhaust gas from the exhaust passage downstream of the NOx adsorber catalyst and recirculates the exhaust gas into the intake passage. The reducing agent adding device adds a reducing agent to exhaust gas upstream of the NOx adsorber catalyst to reduce substances adsorbed by the NOx adsorber catalyst. When or after the reducing agent adding device adds the reducing agent, the torque fluctuation reducing device advances the timing of the fuel injection device or carries out a pilot injection to reduce a fluctuation in engine torque. The reducing agent adding device adds less reducing agent while the torque fluctuation reducing device is operating.
