A spark ignition engine 1 includes a first ignition plug 31 and a second ignition plug 32, each of which is attached to an engine body 10 and forcibly ignites air-fuel mixture in a cylinder 11 during a compression stroke or an expansion stroke. The first ignition plug and the second ignition plug are spaced apart in a predetermined direction. With ascent of a piston 5 during the compression stroke, two vortex flows of the air-fuel mixture are formed in alignment in the predetermined direction with a center of the cylinder being interposed therebetween and in opposite directions from each other. The first ignition plug and the second ignition plug forcibly ignite the air-fuel mixture before the compression top dead center.

The deformable member 13 is made of a material softer than the material of the movable panel 11, and is deformed when the movable panel 11 interferes with the road surface. The deformable member 12 includes a front portion 13a, and a pair of side portions 13b extending toward the vehicle rear side from both end portions of the front portion 13a. Corner portions 13c are formed by the front portion 13a and the side portions 13b of the deformable member 13, and each corner portion 13c has a recess 14 that is recessed toward the inner side of the corner portion 13c.

[Problem] A vehicle display device is provided that is capable of displaying many pieces of information and can make operability good. [Means for Solution] A vehicle display device includes: a display control unit 102 that displays a bar icon F20, which includes a bar F21 and a pointer F22 moving along the bar F21, in a bar icon display region A202; an apparatus control unit 104 that sets a magnitude of a control parameter based on a position of the pointer F22; and a notification unit 102 that executes notification control to notify, to a user, that an operation is accepted when a touch operation is performed on an operation accepting region A201. When a swipe operation to slidingly move an operation position of the touch operation is performed after the notification control is carried out, pointer moving control is carried out in which regardless of whether or not an operation position of the swipe operation is in a bar icon display region A201, the pointer F22 is moved in accordance with a change in the operation position

A moisture absorption film layered product, including a moisture absorption film formed on an at least partial surface of a substrate, wherein the moisture absorption film is formed by curing a photocurable resin composition including at least a trifunctional or more (meth)acryl monomer (A) having no ethylene-oxide-modified (meth)acryloyl group, a trifunctional or more (meth)acryl monomer (B) having at least three ethylene-oxide-modified (meth)acryloyl groups, a hydroxyalkyl (meth)acrylate (C), and a photo-initiator as essential components, relative to 100 parts by weight of a total of the (A), the (B), and the (C), a content of the (A) is 1 to 20 parts by weight, a content of the (B) is 30 to 59 parts by weight, and a content of the (C) is 40 to 69 parts by weight.

[Problem] To be able to cool an entire rotor in a well-balanced manner by using rotation.[Solution] A rotor cooling structure of a rotary electric machine cools by supplying a coolant to a passage in a specific shape. A shaft has an in-shaft passage, into which the coolant flows from one end thereof. A rotor has a first cooling passage, into which the coolant is introduced from an upstream side thereof, and a second cooling passage, into which the coolant is introduced from a downstream side thereof. The first cooling passage has a first introduction passage extending radially outward from the in-shaft passage and a first main passage communicating with a downstream side thereof and extending in an axial direction. The second cooling passage has a second introduction passage extending radially outward from the in-shaft passage and a second main passage communicating with a downstream side thereof and extending in the axial direction. A first bent portion bent in an direction of forward rotation is provided in the first introduction passage, and a second bent portion bent in a reverse rotation direction is provided in the second introduction passage.

An information display control system 1 includes: a vehicle exterior camera 11; vehicle behavior sensors 10; a control unit 20 that acquires vehicle entry prohibition information 6 on the basis of an identified vehicle entry prohibition sign 3a when the vehicle entry prohibition sign 3a is identified from acquired image data; and a display unit 30 that displays the vehicle entry prohibition information 6. When a vehicle 100 enters a travel road 2 on which the vehicle entry prohibition sign 3a is installed, the control unit 20 continues display of the vehicle entry prohibition information 6 by the display unit 30, executes determination processing to determine whether the currently traveling travel road 2 is a vehicle entry prohibition road on the basis of vehicle behavior information and/or the image data, and terminates display of the vehicle entry prohibition information 6 by the display unit 30 when making a negative determination.

The invention relates to a vehicle including a motor (2) that generates torque for driving the vehicle, a power transmission mechanism (4) configured to transmit the torque of the motor (2) to a driving wheel (5) of the vehicle through a plurality of gears, and a control device (20) configured to control the torque of the motor (2). The control device (20) is configured to control the motor (2) to: increase the torque of the motor (2) in a stepwise manner within a range less than a predetermined value larger than zero when backlash elimination in the gears of the power transmission mechanism (4) starts when the vehicle transitions from a deceleration state to an acceleration state; and/or reduce the torque of the motor (2) in a stepwise manner within a range equal to or larger than a predetermined value smaller than zero when backlash elimination in the gears of the power transmission mechanism (4) starts when the vehicle transitions from an acceleration state to a deceleration state.
