Abstract:
A suspension element is disposed inside of a rim. The upper end of the suspension element is connected to a first support member mounted to a vehicle body. The lower end of the suspension element is connected to a second support member rotatably connected to the disk on the wheel. The shock and vibration from the wheel in the vertical direction are damped and absorbed by the suspension element. Also, a spring mechanism and a flat bearing are disposed in the wheel. The spring mechanism is disposed between a rotating member rotatably supported on the vehicle body and the rim of the wheel. If the rotating member is fixed to a brake drum, braking torque is transmitted to the wheel through the spring mechanism. The flat bearing is disposed between the rim and the rotating member and prohibits the axial movement of the wheel relative to the vehicle body.
Abstract:
A wheel with a damper for an automobile includes a rim, a disk, and a damper. The damper includes a rubber member. The rubber member includes a first portion and a second portion. The first portion performs mainly an elastic shear deflection and the second portion acts as a stopper. The first portion extends in an axial direction of the wheel and has an inside surface and an outside surface which contact a space and are not constrained. The end surfaces of the first portion extend perpendicularly to the axial direction of the wheel. A vibrational system having a spring of the first portion of the rubber member and a mass of an automobile is designed so as to have a first natural frequency in a range of 6-12 H, preferably, in a range of 8-10 Hz.
Abstract:
An ink jet printing device including a printing head having a nozzle through which ink can be ejected. The head includes an internal chamber ink and ink ejection is caused by internal pressure pulses. The internal chamber is formed in part by a deformable diaphragm which prevents extreme ambient temperature variations from causing damaging liquid pressure fluctuations.
Abstract:
A printing head for ink-jet printing comprises at least one ink-flow passage in the form of a hollow chamber and at least one ink-jet nozzle coupled to the ink-flow passage. The hollow chamber has a substantially uniform depth over substantially the entire area thereof. Preferably, the head comprises at least two laminated sheet-like members, one of the members having a hollow formed therein to comprise the ink-flow passage, and the other of the members having at least one nozzle formed therein. The head further comprises a flexible wall in communication with the hollowed chamber and a piezoelectric transducer connected to the flexible wall for producing ink-jetting pressure changes in the hollow chamber. Also disclosed are multi-nozzle printing heads with the chambers arranged in a circular configuration, and stacked double and triple decker arrangements.
Abstract:
An elastic wheel comprises a rim for mounting a tire, a disk to be fixed to an axle, and a connecting apparatus for connecting elastically between the rim and disk, the apparatus comprising a pair of axially spaced internal flanges each provided on an inner circumference side of the rim and extending circumferentially, an external flange provided on a radially outer portion of the disk, the external flange disposed in a space between the internal flanges with an axial gap on its both sides and extending circumferentially, a pair of rubber dampers each disposed in the axial gap and connecting between the internal and external flanges, wherein each internal flange is provided on its axially inner side with a first groove, the external flange is provided on its both sides with a second groove so as to face each first groove, axial ends of each damper are inserted into the first and second grooves, and a radial gap is provided between the external flange and the inner circumference side of the rim in the space.
Abstract:
The present invention provides a low carbon steel sheet and a low carbon steel slab on which formation of surface defects can be surely prevented by preventing aggregation of inclusions in the molten steel and finely dispersing inclusions in the steel sheet or slab, and a process for producing the steel sheet and slab. The present invention provides a process comprising the steps of decarburizing a molten steel so as to produce a carbon concentration of up to 0.01% by mass, pre-deoxidizing the molten steel by adding Al thereto so as to produce a dissolved oxygen concentration from 0.01 to 0.04% by mass, adding thereto Ti and at least La and/or Ce, and casting the molten steel, and a steel sheet and a steel slab obtained by the process.

Abstract:
A laterally installing wheel including a rim in which a rim main portion and a side ring are disconnectably coupled to each other at a coupling portion of the rim main portion and the side ring, wherein the coupling portion is constructed such that a gap between the rim main portion and the side ring is inconspicuous from outside in the axial direction of the wheel. The coupling portion is provided at an axially inner portion of the rim. In a case where the coupling portion is provided at an axially outer portion of the rim, the coupling portion is located at an inconspicuous portion.
Abstract:
[Problems]To provide a wheel assembly allowing the elimination of an installation space for suspension element on the outside of a wheel and capable of satisfactorily damping and absorbing shock and vibration in the vertical direction. [Means for Solving Problems]Suspension element (70) is disposed, in a generally raised state, inside of a rim (11). The upper end of the suspension element (70) is connected to a first support member (50) mounted to a vehicle body. The lower end of the suspension element (70) is connected to a second support member (60) rotatably connected to the disk (12) on the wheel (10). The shock and vibration from the wheel (10) in the vertical direction are damped and absorbed by the suspension element (70). Also, a spring mechanism (30) and a flat bearing (40) are disposed in the wheel (10). The spring mechanism (30) is disposed between a rotating member (20) rotatably supported on the vehicle body and the rim (11) of the wheel (10). In the case the rotating member (20) is fixed to a brake drum, braking torque is transmitted to the wheel (10) through the spring mechanism (30). The flat bearing (40) is disposed between the rim (11) and the rotating member (20) and prohibits the axial movement of the wheel (10) relative to the vehicle body.
Abstract:
A run-flat core has a closed upper surface and an open lower surface and includes a reinforcement plate provided for reinforcement within the core. The core includes one or more blocks formed in the same shape with each other and connected in a circumferential direction of a wheel. The core has flanges protruding in right and left directions at a lower portion of the core. A band is wound onto the flanges, and by tensioning the band, the core is pressed to a rim. The blocks are connected to each other at a lower portion of the core. The core may include a longitudinal groove, and by winding the band onto the longitudinal groove, the core is pressed to the rim.
