  • Patent number: 11535127
    Abstract: A seat mounted in the cabin of a vehicle has side supports for supporting the respective right and left lateral sides of the upper half body of an occupant. The seat also has a seat frame and a side support frame incorporated in the side support on the inner side in the vehicle width direction and secured on the seat frame. A console box is mounted adjacent to the seat, on the inner side of the seat in the vehicle width direction. The side support frame and the console box or the console frame are positioned so as to at least partially overlap each other in a side view.

  • Patent number: 11043825
    Abstract: A power supply device includes a spike absorption circuit that suppresses an avalanche breakage of a current shutdown switch due to a kickback voltage that may appear in response to the cut-off of a load current. The current shutdown switch is connected to secondary batteries. The spike absorption circuit is a series circuit of a protection switch, formed of a semiconductor element, and a diode. The power supply device further includes: a small-signal switch that controls turn-on and turn-off of the protection switch; and a delay circuit that maintains the small-signal switch in an ON state over a setup time after a current shutdown timing of the current shutdown switch. The delay circuit maintains the small-signal switch in the ON state over the setup time (T), and the small-signal switch thereby causes the protection switch to the ON state. Then, the spike absorption circuit damps the kickback voltage.

  • Patent number: 9890481
    Abstract: The purpose of the present invention is to provide a method whereby deposits which have occurred on the surfaces of a fiber bundle during flameproofing treatment of a carbon fiber-precursor acrylic fiber bundle can be efficiently removed prior to carbonization treatment at high temperature. The method for production of carbon fiber bundle includes a step in which, after a carbon fiber-precursor acrylic fiber bundle has been heated and undergone flameproofing treatment, the fiber bundle is subjected to a plasma treatment involving contact with a plasma gas in gas phase, or to an ultraviolet treatment involving irradiation with ultraviolet in gas phase; and a step in which the fiber bundle having undergone the plasma treatment or the ultraviolet treatment is subjected to a carbonization treatment.

  • Patent number: 9487178
    Abstract: A head-protecting airbag device includes an airbag that is inflatable in such a manner as to separate an inboard side wall and an outboard side wall while unfolding downward from a housing. The airbag includes a front inflatable shielding region that covers an inboard side of a window and includes a sub inflatable region that is inflatable later than the main inflatable region. The sub inflatable region includes a supportive inflatable region that is supported by a vehicle body member which is disposed below a beltline. The airbag is stored in the housing such that a front lower corner of the sub inflatable region is folded inward on a crease extending obliquely rearward and downward from the front edge to the lower edge of the airbag before the airbag is subjected to a vertical size reducing folding that brings the lower edge as unfolded flatly close to the upper edge.

  • Publication number: 20100200914
    Abstract: A source layer 13 is so high that the source layer 13 and a source electrode 20 can be connected to each other mainly by the sides of the source layer 13. Thus, the width of the source layer 13 can be minimized and size reduction can be achieved. At the same time, insulating films 19 with a sufficient thickness can be formed in trenches 15 and thus the insulating films 19 are not formed on the source layer 13. Thus it is possible to deeply form a recessed structure 17 while suppressing unevenness on the source electrode 20, thereby improving a breakdown voltage.
