In a tread-forming surface of a mold, a contour of a land surface-forming portion located between two projections among at least three land surface-forming portions can be represented by a single circular arc that is convex outward. In a case where, of the two projections, one projection is a wide projection and the other projection is a narrow projection, when a surface that has a contour represented by at least one circular arc and that is tangent to the at least three land surface-forming portions is defined as a reference surface of the tread-forming surface, a drop distance from the reference surface to an end on the wide projection side of the land surface-forming portion can be longer than a drop distance from the reference surface to an end on the narrow projection side of the land surface-forming portion.

Tire mold, production method for tire, and tire

In a tire, a length from a center PM in an axial direction of a boundarybetween a coreand an apexto an outer edge PA of the apexis not less than 10 mm and not greater than 15 mm. In a state where the tireis mounted on a normal rim and an internal pressure of the tireis adjusted to 10% of a normal internal pressure, a main body portionof a carcass plyextending along an inner surfaceof the apexis tilted relative to the axial direction, and an angle of the main body portionrelative to the axial direction is not less than 40&#xb0; and not greater than 60&#xb0;.

Pneumatic tire

In a tire, a tread includes a cap layer, an intermediate layer formed such that a loss tangent of the intermediate layer at 30&#xb0; C. is less than a loss tangent of the cap layer at 30&#xb0; C., and a base layer formed such that a loss tangent of the base layer at 30&#xb0; C. is less than the loss tangent of the intermediate layer at 30&#xb0; C. The intermediate layer is disposed outwardly of the base layer and the cap layer is disposed outwardly of the intermediate layer, in the radial direction. An outer end of the intermediate layer is disposed outwardly of an outer end of the base layer and an outer end of the cap layer is disposed inwardly of the outer end of the intermediate layer, in the axial direction. A difference between an axial width of the cap layer and an axial width of the base layer is not less than &#x2212;10 mm and not greater than 10 mm.

Tire

In a tire, a shape index of a reference ground contact surface is not less than 1.20 and not greater than 1.50. In the tire, a tread includes a cap layer, an intermediate layer formed such that a loss tangent of the intermediate layer at 30&#xb0; C. is less than a loss tangent of the cap layer at 30&#xb0; C. and a base layer formed such that a loss tangent of the base layer at 30&#xb0; C. is less than the loss tangent of the intermediate layer at 30&#xb0; C. In the radial direction, the intermediate layer is disposed outwardly of the base layer and the cap layer is disposed outwardly of the intermediate layer. In a shoulder land portion of the tread, a thickness of the cap layer at a center of an axial width is less than a thickness of the cap layer on the shoulder circumferential groove side.

A tireincludes a tread, a pair of sidewalls, a pair of beads, a carcass, a belt, an inner liner, and a pair of insertion layersdisposed between the carcassand the inner liner. Each insertion layeris disposed between an end of the beltand an end PB of the bead. Each insertion layerhas a volume resistivity of less than 10&#x3a9;&#xb7;cm. A complex elastic modulus of the insertion layeris equivalent to or higher than a complex elastic modulus of the inner liner. A thickness of each sidewallat a maximum width position PW is not greater than 5.0 mm.

Tire for automobile

A notification device includes a notification line for notifying a vehicle control device that a door is closed, a first door lock switch that electrically connects the notification line when the door is closed and disconnects the notification line when the door is opened, and an interruption unit that interrupts a signal transmitted through the notification line when an abnormality of the first door lock switch is detected.

Notification device and door opening-closing device

A pneumatic tire includes a tread portion including an inboard shoulder land portion defined between an inboard tread edge and an inboard shoulder main groove. The inboard shoulder land portion is provided with inboard semi-open shoulder lateral grooves and inboard shoulder sipes extending axially inwardly from the inboard tread edge and terminate within the inboard shoulder land portion.

A vehicle door locking device includes a switching portion capable of switching between a first state in which the switching portion makes contact with a door to inhibit the door from moving in an opening direction no less than a distance required for removing an object caught in the door, and a second state in which the movement of the door of no less than the distance is not inhibited. The switching portion has a cam that rotates according to an opening/closing operation of the door. The rotation of the cam by a predetermined angle or more is inhibited in the first state, and the rotation of the cam is allowed in the second state.

Vehicle door locking device

A vehicle door is operated in accordance with a desired speed pattern. A vehicle door opening-closing control deviceincludes a power-supply voltage detecting unitthat outputs a detection value of a power-supply voltage of an electric motor, a reference control pattern storage unitthat stores a reference control pattern that indicates a voltage command value or a speed command value for the electric motor, the reference control pattern is a control pattern of the electric motor when the detection value is within a predetermined range, a control pattern generating unitthat generates a corrected control pattern that is obtained by correcting the reference control pattern based on the detection value, and a PWM control unitthat controls the electric motorbased on the corrected control pattern.

Vehicle door opening and closing control device

An opening and closing apparatus with a lock that is provided is capable of safely and promptly closing a sliding door, and also easily performing unlocking with a simple configuration. In an opening and closing apparatus with a lock for opening and closing sliding doors that are provided with elastic members at their door leading ends, output of an electric motor is transmitted to a rack-and-pinion mechanism or a lock mechanism. A control unit controls the electric motor such that a closing operation is performed, the closing operation operates the rack-and-pinion mechanism so as to move the sliding doors to a fully closed position and then displacing a link mechanism in a lock mechanism from an unlocking position to a locking position. Furthermore, the control unit controls the electric motor so as to reduce the output of the electric motor at a predetermined intermediate time point during the closing operation.
