    Abstract: A water stop member of a crimp terminal is affixed to the inner wall surface of an electric wire connecting portion of a terminal fitting before crimping and forms into a first water stop area, a second water stop area, and a third water stop area after the crimping. The first water stop area suppresses entering of water from a space between the outer wall surface of a first barrel piece and the inner wall surface of a second barrel piece in the electric wire connecting portion. The second water stop area suppresses entering of water from the side closer to a terminal connecting portion of the terminal fitting than the distal end position of a core wire. The third water stop area suppresses entering of water from a space between the inner wall surface of a cover crimping portion of the electric wire connecting portion and a cover.

  • Publication number: 20170180370
    Abstract: An information collection method includes determining whether or not a vehicle satisfies predetermined conditions when a target device receives a test mode start request from an collection device, and when it is determined that the vehicle satisfies the predetermined conditions, starting the test mode. In the test mode, update of a predetermined counter is stopped. The collection device generates a first MAC based on the count value received from the target device and transmits an attack information acquisition request with the first MAC to the target device. If the attack information acquisition request with the first MAC is received from the collection device, the target device generates a second MAC based on the stopped count value, determines that the host device is normal in a case where the first MAC and the second MAC coincide with each other, and transmits the attack information to the collection device.

  • Publication number: 20170173679
    Abstract: In a die casting apparatus, during feeding of molten metal by an electromagnetic pump, a molten metal level sensor repeatedly detects a during-feeding level of the molten metal stored in a molten metal holding furnace; a control unit corrects a molten metal feeding voltage to a during-feeding voltage based on the repeatedly detected during-feeding level of the molten metal such that an amount of the molten metal fed by the electromagnetic pump coincides with a prescribed amount; the control unit applies the during-feeding voltage to the electromagnetic pump to cause the electromagnetic pump to feed the molten metal from the molten metal holding furnace into a plunger sleeve; and casting is performed through an injecting operation in which the molten metal fed into the plunger sleeve is extruded by a plunger tip to be injected into a cavity.

  • Patent number: 9682701
    Abstract: The control unit of the fuel cell system monitors the status of power generation of the fuel cell and calculates a total amount of the fuel gas consumption, based on the amount of power generated by the fuel cell, from a point in time when the supply gas pressure reaches a standard gas pressure. Another total amount of the fuel gas consumption is calculated based on a gas pressure change that corresponds to a decrease of the gas pressure from the standard gas pressure. Comparing two total amounts of the fuel gas consumptions, the evaluation is performed as whether the on-off valve in the fuel gas flow path from each of the fuel gas tanks to the fuel cell fails to be opened.

  • Patent number: 9682703
    Abstract: A driving support device performs collision avoidance support on a vehicle relative to a leading vehicle present in a travelling direction based on a time-to-collision Ta as a time that the vehicle takes to collide with the leading vehicle. A lateral change amount calculation portion detects relative lateral velocity Vy, which is a relative time-dependent change amount between the vehicle and the leading vehicle. A storage portion stores steering time T1, which is a time required for the vehicle to avoid the leading vehicle by steering. The storage portion stores activation threshold TH1, which is a threshold to determine activation of the driving support based on the relative lateral velocity Vy. When a relative lateral velocity Vy at a time when the time-to-collision Ta is the steering time T1 or more is the activation threshold TH1 or more, a support management portion restrains the activation of the driving support.
