Abstract: In a vehicle wheel of the present invention, a sub-air chamber member functioning as a Helmholtz resonator includes a main body section forming a sub-air chamber in a space surrounded by a bottom plate adjoined to the outer circumferential surface of a well section and extending in a wheel width direction, an upper plate opposed to the bottom plate at a predetermined interval on an outer side in a wheel radial direction of the bottom plate, and a pair of side plates standing outward in the wheel radial direction from both ends in the wheel width direction of the bottom plate, and a pair of edge sections which extend outward in the wheel width direction from respective joining sections of the bottom plate and the pair of side plates, and which are locked to the well section.

Abstract: Provided is a vehicle wheel with a sub-air chamber member as a Helmholtz resonator attached to a rim. The sub-air chamber member includes a main body having a sub-air chamber therein, a tubular body providing communication between the sub-air chamber and a tire air chamber, and a cover member covering the main body. The main body is disposed on a rim inner circumferential surface portion of the rim present on an inner side of the rim in a wheel radial direction and extending in a wheel width direction. The tubular body is disposed in a through-hole provided in the rim so as to provide communication between the inner side of the rim in the wheel radial direction and the tire air chamber side. The cover member covers the main body from an inner side in the wheel radial direction.

Abstract: A vehicle wheel includes: a wheel having a rim; a sub-air chamber member serving as a Helmholtz resonator; and a support member integrated with the sub-air chamber member and joined to the rim. The sub-air chamber member is made of a synthetic resin. The support member is made of a metal.

Abstract: A tire-wheel assembly includes: a wheel having a pair of bead seats and a well portion; a tire having a pair of tire beads seated on the pair of bead seats; a lid body having two edge portions located opposite each other in a wheel width direction; and a sub-air chamber member disposed on the lid body. Each of the two edge portions is sandwiched between corresponding one of the pair of bead seats and corresponding one of the pair of tire beads so that the lid body is arranged above the well portion.

Abstract: A first material layer, a second material layer, and a photoresist layer may be formed over a substrate. The second material layer may be patterned by transfer of a lithographic pattern therethrough. A conformal spacer layer may be formed over the patterned second material layer in a chamber enclosure of an in-situ deposition-etch apparatus. Spacer films may be formed by anisotropically etching the conformal spacer layer in the chamber enclosure of the in-situ deposition-etch apparatus. The first material layer may be anisotropically etched using a combination of the patterned second material layer and the spacer films as an etch mask in the in-situ deposition-etch apparatus. A high fidelity pattern may be transferred into the first material layer with reduced line edge roughness, reduced line width roughness, and without enlargement of lateral dimensions of openings in the first material layer.

Abstract: Provided is a vehicle wheel to have a Helmholtz resonator mounted to a rim with an old structure, without circumferential grooves cut in the rim so as to have the Helmholtz resonator mounted therein. A vehicle wheel (1) includes a rim (11) formed by joining an inner rim (14a) and an outer rim (14b), and a sub air-chamber member (10) as a Helmholtz resonator, wherein the sub air-chamber member (10) is mounted to the rim (11) via a support member (20) held between the inner rim (14a) and the outer rim (14b).

Abstract: A vehicle wheel includes a Helmholtz resonator (sub-air chamber member) adhered on a rim, and the Helmholtz resonator (sub-air chamber member) includes a bottom plate and a side plate that rises from one edge of both edges of the bottom plate, and the bottom plate and the side plate are adhered on the rim. In the vehicle wheel, the Helmholtz resonator further includes an upper plate that is opposed to the bottom plate, and the upper plate is connected to the side plate at an opposite side of the one edge and inclined so as to come near the bottom plate at greater distances from the side plate.

Abstract: A negative electrode active material containing a negative electrode active material particle which includes a silicon compound particle containing a silicon compound (SiOx: 0.5?x?1.6). The silicon compound particle has three or more peaks in a chemical shift value ranging from ?40 ppm to ?120 ppm but has no peak in a chemical shift value within a range of ?65±3 ppm in a spectrum obtained from 29Si-MAS-NMR of the silicon compound particle. This provides a negative electrode active material capable of improving cycle characteristics when it is used as a negative electrode active material for a secondary battery.

Abstract: A rim section 18 is provided with e disk section 20 and is secured to a jig by patting the disk section 20 as the lower side. By allowing a groove section 40 (an engaging section) provided along a circumferential direction of the inner peripheral surface 21 of the rim section 18 to engage with a bent end section 48 of a reinforced member 14 attached from the upper side of the jig, the reinforced member 14 can be easily positioned on the inner peripheral surface 21 of the rim section 18.
