Upon self-alignment of a steering wheel, a steering wheel body has its ring plane displaced toward the vertical plane by plastic deformation of the steering wheel core. There is located a switch operation portion in at least one of the two front spokes neighboring a front space inside the ring portion and generally symmetrically arranged relative to the boss portion. The cores of the front spokes are further provided at positions generally symmetric relative to the boss portion and to the boss portion relative to the switch operation portion with deformable portions, respectively, to be twist-deformable upon self-alignment.

[Problem to be Solved] To provide an organic electroluminescence device with heat resistance capable of being driven by a low voltage.[Solution] An organic electroluminescence device includes a pair of anode and cathode opposed to each other; and a plurality of organic semiconductor layers layered or disposed between the anode and the cathode, the organic semiconductor layers including a light-emitting layer. At least one of the organic semiconductor layers contains a bulky organic semiconductor compound having an aromatic multi-membered ring structure and at least three aromatic substituents bonded thereto. Each of the aromatic substituents is arranged in a manner that a dihedral angle between a ring plane of the aromatic multi-membered ring structure and the ring plane of the aromatic substituent is within 70 to 90° determined by a semiempirical molecular orbital calculation method.

A birdcage resonator for magnetic resonance applications has two ferrules disposed in spaced-apart parallel ferrule planes. A line connecting the ferrule centers defines the antenna axis of the birdcage resonator, which orthogonally intersects the ferrule planes. The birdcage resonator has a number of antenna rods regularly distributed around the antenna axis, extending from ferrule to ferrule. The birdcage resonator has two coupling rings in addition to the ferrules that surround the antenna axis in respective coupling ring planes orthogonal to the antenna axis, and that are spaced from but coupling with the ferrules. The coupling rings are tuned to cause the ferrules to be resonant at frequencies other than without the coupling rings. The ferrules couple with one another in common eigenmodes, namely a common mode with a common mode frequency, and a push-pull mode with a push-pull frequency differing from the common mode frequency. The coupling rings are tuned such that the frequency of one of the eigenmodes does not correspond with any resonance frequency of the antenna rods. A feed device feeds electrical energy into the ferrules at the frequency of the eigenmode that corresponds with no resonance frequency of the antenna rods.

The steering wheel includes a wheel body and an airbag apparatus disposed on top of a boss. The wheel body is divided into a shaft side division joined to the steering shaft, and a ring side division disposed proximate the ring. The ring side division is rotatable with respect to the shaft side division such that a ring plane is aligned generally vertically. The boss includes an actuator that rotates and moves the ring side division to align the ring plane generally vertically. The actuator completes its operation to align the ring plane generally vertically by the time a driver contacts the inflated airbag in the course of forward motion.

An organic semiconductor material comprising a compound which has a generalized porphyrin skeleton and which has a molecular structure such that the distance from the generalized porphyrin ring plane to the center of each atom forming the generalized porphyrin skeleton, is not more than 1 Å

The invention relates to a roller bearing arrangement (1, 26, 31, 34, 36, 37), preferably a large-scale roller bearing with a diameter of 0.5 m or more, for mounting parts of an energy system, in particular as blade bearings for a wind turbine, comprising at least two annular counter-rotatable elements (2, 3), arranged concentrically to one another and one inside another at least in areas, for connecting to counter-rotatable parts of the energy system. Two counter-rotatable connecting elements (2, 3) are separated from one another by a gap (4) and overlap one another radially, at least in part. Furthermore, at least two rows of rolling bodies (17, 18) are provided in the area of the gap (4) in radially overlapping areas of the annular connecting elements (2, 3), each row rolling along two tracks (19, 20) overlapping one another in the radial direction at least in areas. One or more tracks (19, 20) for rolling bodies (17, 18) are arranged in radially overlapping sections (5, 6) in such a manner that the angle of support, which is enclosed by the connection line between the centres of the contact points of a rolling body (17, 18) with the two tracks thereof opposite the ring plane, is greater than or equal to 45°, with the result that such an axial roller bearing is used for transmission of predominantly axially acting force components. At least one additional bearing for transmission of predominantly radially acting force components is provided, the support angle of which is less than 45°, preferably 25° or less, in particular 10° or less, wherein at most such tracks for radial roller bearings, the maximum distance of which perpendicular to the track surface is equal to or less than 25% of the largest distance perpendicular to the track surface between two tracks of an axial roller bearing row, are introduced directly into the annular connection elements (2, 3).
