  • Patent number: 10121999
    Abstract: A degassing hole is formed in a casing in which a storage element is housed. Prior to forming the degassing hole, the casing is clamped in a region between the outer peripheral edge of the casing and the storage element where the degassing hole is to be formed such that overlapped films of the casing are pressed tightly together. By displacing the acting position of the clamping force toward the storage element while reducing the clamping force gradually toward the storage element prevent, liquid spill in a degassing process is prevented.

  • Patent number: 10099677
    Abstract: A vehicle control device is provided with a friction clutch for engaging and disengaging a motor/generator and a drive wheel, a mechanical oil pump driven by the motor/generator to supply hydraulic oil pressure to the friction clutch, an electric oil pump driven by an electric motor to supply hydraulic oil pressure to the friction clutch, and a control unit. The control unit stops a motor/generator when a vehicle stops; maintains a release of a friction clutch when slack in the stroke is eliminated by the hydraulic oil pressure from the electric oil pump; raises a rotational speed of the motor/generator toward a target rotational speed upon a request to cancel stoppage of the motor/generator; and restricts the torque to be less than the motor generator torque at which the target rotational rate can be maintained when the rotational rate of the motor/generator is raised toward the target rotational rate.

  • Patent number: 10100772
    Abstract: A fuel injection control device controls a spark-ignition engine of an intra-cylindrical direct fuel injection type. The engine includes a fuel injection valve configured to directly inject a fuel to an interior of a cylinder, and a spark plug configured to ignite, by a spark, an air-fuel mixture inside the cylinder. When the injected fuel collides with a portion in a predetermined low-temperature state, the fuel is injected while changing a fuel injection condition under predetermined operating conditions so as to restrain a fuel spray from keeping colliding with the same position continuously.

  • Patent number: 10099327
    Abstract: A device for press-fitting an oil seal S that includes a fixing section F in which a hard ring S is embedded and a lip section L into a structure A. The device includes an air hammer AH that includes a hammer head 1. The hammer head 1 includes a pressing section 6 configured to abut the fixing section F and a holding section 7 configured to abut the lip section L, and a negative pressure space 8 is formed between the hammer head AH and the oil seal S between the pressing section 6 and the holding section 7. The hammer head 1 is provided with an air suction path 11 that is open to the negative pressure space 8 at one end and is connected to an air suctioning means 10 at the other end. Accordingly, the device holds by suction the oil seal S having a complicated shape without deforming it, and adequately press-fits it into a structure A.

  • Patent number: 10099695
    Abstract: A hybrid vehicle control device is provided that is capable of controlling a drive source according to a travel plan. The hybrid vehicle control device is configured to be mounted in a hybrid vehicle including a drive source having an engine and a motor/generator, and a navigation system that acquires travel environment information of a planned travel route. The control device is configured such that, upon selection of a “travel plan mode”, which controls the drive source according to a travel plan set for low fuel travel based on travel environment information acquired from the navigation system in the absence of the selection of an “eco-mode”, which controls the drive source to prioritize fuel efficiency over power performance, the selection of the “travel plan mode” is linked with a setting operation for the “eco-mode”.
