  • Publication number: 20200025249
    Abstract: Entanglement of bush main bodies is suppressed. At a bush, a shaft portion of a bush main body, which extends in a circumferential direction of a mounting hole of an outer anchor, covers a peripheral surface of the mounting hole. A first flange portion and a second flange portion of the bush main body are placed on an front and back sides of the outer anchor, respectively. Moreover, a connection portion connects both circumferential direction sides of the bush main body. The connection portion allows elastic deformation of a diameter of the bush main body, and the second flange portion can pass-through the mounting hole.

  • Patent number: 10518744
    Abstract: A webbing take-up device includes a spool, a lock gear that restricts pull-out direction rotation of the spool, a force limiter mechanism that permits pull-out direction rotation of the spool at or above a force limiter load, and a pawl that switches the force limiter load. The webbing take-up device further includes a cylinder section that includes a first cylindrical portion and a second cylindrical portion, a gas generator that supplies gas into the second cylindrical portion, and a piston section that is moved along the first cylindrical portion by an increase in pressure inside the second cylindrical portion and the first cylindrical portion so as to press and displace the pawl. An axial center of the second cylindrical portion is disposed offset with respect to an axial center of the first cylindrical portion, and an abutted portion that is abutted by the piston section is provided at a boundary between the first cylindrical portion and the second cylindrical portion.

  • Patent number: 10513421
    Abstract: The present disclosure presents a webbing take-up device, which comprises: a spool; a lock section that is restricted from rotating at a time of a vehicle emergency so as to limit rotation of the spool in the pull-out direction; a force limiter mechanism that permits rotation of the spool in the pull-out direction at a force limiter load or greater when rotation of the spool in the pull-out direction with respect to the lock section is being limited; a switching member that switches a load value of the force limiter load by switching between a rotation-restricted state and a rotation-enabled state; and a mounting member that includes a switching member mounting section at which the switching member is disposed, and a restriction section that is engaged with the switching member so as to restrict displacement of the switching member disposed at the switching member mounting section.

  • Patent number: 8103818
    Abstract: In a memory module 100, an address generating circuit 120, using the highest order bit of a row address output by a memory controller 12, will generate a highest order bit BA2 of a bank address insufficient for the purpose of identification of a memory cell targeted for access, and will output the bit to SDRAM 110. An operating mode detector 130 detects the operating mode of the memory controller 12. A switch controller 40 will switch a switch 128 on the basis of the detected operating mode.

  • Patent number: 7167967
    Abstract: A computer body outputting a predetermined number of address signals A0 to A11 and a plurality of select signals CSO and CSI, generates a memory select signal CS and an additional address signal A12 added to the signals A0 to A11 according to the inputted signals CSO and CSI, and provides the signal CS, signal A12, and signals A0 to AI1 to a 256-megabit SDRAM (memory), so that the computer body can access the corresponding data. The computer body can access the data corresponding to the generated additional address signal A12 and predetermined number of the address signals A0 to A11.

  • Publication number: 20050114622
    Abstract: A computer body outputting only address signals A0 to A11 could use only a half area of a 256-megabit SDRAM. The memory circuit 30 receives a predetermined number of address signals A0 to A11 and a plurality of select signals CS0 and CS1, generates a memory select signal CS and an additional address signal A12 added to the signals A0 to A11 according to the inputted signals CS0 and CS1, and provides the signal CS, signal A12, and signals A0 to A11 to a 256-megabit SDRAM (memory), so that the computer body can access the corresponding data. The computer body can access the data corresponding to the generated additional address signal A12 and predetermined number of the address signals A0 to A11.
