  • Patent number: 9969996
    Abstract: A method for making a mutated pullulanase enzyme that hydrolyzes an ?-1,6-glycosidic linkage is provided. The method includes obtaining the amino acid sequence of a pullulanase enzyme having an amino acid sequence that is at least 95% identical to the amino acid sequence set forth in SEQ ID NO: 13; identifying an amino acid to be mutated in the pullulanase enzyme of step (1), wherein the amino acid to be mutated corresponds to the amino acid at position Phe476 of SEQ ID NO: 2; constructing a mutated amino acid sequence by substituting the amino acid to be mutated with another amino acid or deleting the amino acid to be mutated, thereby making a mutated pullulanase enzyme having the mutated amino acid sequence that has increased affinity for pullulan and that hydrolyzes an ?-1,6-glycosidic linkage.

  • Patent number: 9079559
    Abstract: An airbag includes a vent hole discharging gas, a slide tether performing transition of a state of the vent hole, from an open state via a close state to the open state, by changing between a slackened state and an extended state, and a slide tether cover guiding the slide tether. The other end portion in a longitudinal direction of the slide tether body portion constitutes a first supporting point by being fastened in a direction going from the vent hole toward a mounting position of the inflator, bifurcated portions constitutes a second supporting point by the other end portion of the slide tether cover being fastened, terminal end portions of leg piece portions constitute a third supporting point by being respectively fastened. When the airbag is deployed, transition of a state of the vent hole is performed.

  • Patent number: 8573642
    Abstract: The present invention provides an airbag device that is capable of restraining a rectification cloth that switches a vent hole to an opened or closed state so as not to be twisted, and that is capable of switching the vent hole from an opened state to a closed state, and further, switching to the opened state. At an initial stage at which an airbag main body inflates and expands, the vent hole 8 is arranged between the leg portions 5, and when the airbag main body is in a predetermined internal pressure state, the vent hole is closed by means of the band-shaped portion 4. If an occupant or the like comes into contact with the airbag main body, a tense state of each of the leg portions is released, the rectification cloth is established in a slackened state, and the vent hole 8 is established in an opened state.

  • Patent number: 8537686
    Abstract: An ATM switch allowing simplified OAM processing only on the line incoming side is disclosed. An incoming line circuit has a header conversion table storing information indicating whether the system is an end point of an OAM processing flow for each connection and an OAM table storing an AIS flag and an RDI flag for each connection. As for an OAM cell found by referring to these tables to be forced to go back to its own port, an switch output port number is rewritten in the OAM function section. In addition, in the case of an AIS cell, the function type is rewritten so as to become an RDI cell. In the case of an LB cell, the LB indication is rewritten so as to become a return LB cell, and switching to its own port is conducted in the ATM switch core.
