  • Patent number: 7946375
    Abstract: The disclosed seat belt retractor and seat belt apparatus may comprise: an electric motor; a spool that is capable of winding and unwinding a seat belt for occupant restraint in association with the driving of the electric motor; and a controller for controlling the electric motor. A starting condition can be defined by the state of the seat belt relative to a vehicle occupant and the state of a vehicle door corresponding to the seat belt and, in cases where a starting condition is satisfied, the controller can be configured to control the electric motor to rotate in the belt winding direction such that the motor output of the electric motor is varied according to a satisfaction pattern of the starting condition.

  • Patent number: 7941563
    Abstract: A packet sent in a mobile IP communication between different regions passes through a particular address translation unit, so that the communication route cannot be optimized. The packet cannot be delivered to a mobile node not having a fixed home address. To overcome the difficulties, the address translation unit includes a function to process the mobile IPv6 protocol. The mobile node includes a function to dynamically acquire a home address. A first network and a second network each identify the mobile node by a SIP (session initiation protocol) identifier. The mobile node acquires a home address on the second network and registers a corresponding relation between the identifiers and the home address thereof. A terminal on the second network acquires the home address of the mobile node from information of the mobile node registered to the SIP server according to a SIP procedure.

  • Publication number: 20110029621
    Abstract: A mail server system includes a congestion control management section managing a congestion control over the mail server system, a congestion statistical information collection section collecting the congestion statistical information of each mail server, and a resend queue having enough capacity, wherein a retry server for performing a retry process is provided. The congestion control management section detects the mail server where a fault occurs from the collected congestion statistical information and gives an instruction of regulating the sending of a mail directed to the faulty mail server to each mail server. The mail server instructed the regulating the sending of the mail directed to the faulty mail server transfers all the mails directed to that destination to the retry server, and transfers the received mail directed to the faulty mail server to the retry server until there is a regulation dissolution instruction from the congestion control management section.

  • Publication number: 20100292039
    Abstract: An oil-free chain is constructed by alternately connecting a pair of outer link plates connected using pins and a pair of inner link plates connected using oil-impregnated bushings into which the adjacent pins of the outer link plates adjacent to the inner link plates are fitted. The oil-impregnated bushings are impregnated with a lubricant having a kinematic viscosity in the range of ISO-VG grade 46 to 460, the weight % of an ingredient having the highest content among the elution ingredients obtained by the GPC method is 95 wt % or more, Mn is 800 or more and 2300 or less, and the ratio of Mw to Mn is 1.0 or more and 1.3 or less. Oil film breakage at the sliding portions of the bushings is suppressed from occurring and the oil film strength is high such that an oil-free chain has a sufficiently long abrasion elongation-resistant life.

  • Publication number: 20100288627
    Abstract: An atomizing apparatus (10) includes a housing (12), and a tank (40) accumulates tap water inside the housing. By electrolyzing the tap water by the electrolysis electrodes (120p, 120m), the water in the tank becomes electrolyzed water. At the first operation after a shortage of water state in the tank is detected, an initial electrolysis operating time is set to 20 minutes (step S210). In a case of not an operation after the shortage of water state but a restart of a normal operation, the initial electrolysis operating time is set to 5 minutes (step S224).

  • Patent number: 7793984
    Abstract: A seatbelt retractor integrated with an electronic control unit. A motor is disposed above both side walls of a frame and on the same side as a spool with respect to a back board. The motor is detachably fixed to at least one of the back board and the both side walls and of the frame. The ECU is detachably mounted to an upper stay extending upward from the back board of the frame and to be mounted to the vehicle body. In this manner, the motor and the ECU are integrated with a seatbelt retractor. Since the ECU is mounted to the upper stay, the weight of the ECU is dispersed not only to the main body of the seatbelt retractor but also to the upper stay. Thus, the vibration of the seatbelt retractor may be reduced.

  • Patent number: 7753158
    Abstract: A seat belt retractor, which is capable of winding and unwinding a seat belt for occupant restraint by mechanism of an electric motor, removes slack of the seat belt and controls the restraining feeling on a vehicle occupant to be as little as possible. A seat belt retractor of a seat belt apparatus to be installed in a vehicle is adapted to control a motor to perform an action of increasing seat belt tension to wind up a seat belt which is excessively unwound from the spool when a vehicle occupant wears the seat belt and to be driven according to such a setting that, at the initial stage of the action of increasing the seat belt tension, the tension increasing rate until the seat belt tension reaches a target tension is lower than a predetermined rate.
