  • Patent number: 10974682
    Abstract: An airbag device has an airbag that is wound in a rolled state, mounted in a vehicle longitudinal direction of a vehicle and deployable in a curtain-like manner in a vehicle compartment by a gas generated by an inflator in case of emergency. A cover cloth is provided so as to be wound to cover at least part of an outer circumference of the airbag extending in a longitudinal direction. The cover cloth has a first folded-back part that is formed by folding back one end of the cover cloth in a circumferential direction of the outer circumference of a cross section, which is perpendicular to the longitudinal direction of the folded airbag. An edge of the outer circumference of the airbag is held between the first folded-back part and the other end of the cover cloth.

  • Patent number: 10769011
    Abstract: A memory device includes a semiconductor memory unit, a controller circuit configured to communicate with a host through a serial interface, store write data to be written into a page of the semiconductor memory unit in a data buffer, and an error-correcting code (ECC) circuit configured to generate an error correction code from the write data if the ECC circuit is enabled. The controller circuit writes the error correction code with the write data into the page if the ECC circuit is enabled. A maximum column address of the page which is accessible from the host changes depending on whether or not the ECC circuit is enabled.

  • Patent number: 10654438
    Abstract: A curtain airbag apparatus (100) is provided with an inflator (106), and a cushion (102) stored, in an elongated storage form, on an inner side of a headliner above a front side window (110), and receives the gas to inflate. The cushion (102) in the storage form has a bent-over portion (142) which is formed by bending over a rear end (136) of the cushion (102) towards a center side thereof from a state in which the cushion (102) is rolled upwards. The state of the cushion (102) when the bending over is performed i.e. the rolled state of the cushion (102), is achieved by rolling the cushion (102) from a state in which a prescribed area at the rear end (136) of the cushion (102) in a deployed state is folded over towards the center side in the vehicle front-rear direction.
