A hinge device for connecting first and second objects includes a base seat and a sliding member slidably connected to the base seat through a coupling member to be turned about a rotating axis between folded and unfolded states. In the folded state, first and second object connecting sections of the base seat and the sliding member are disposed at two opposite sides of a mounting section of the base seat to allow folding of the objects to each other. In the unfolded state, the second object connecting section is placed above the first object connecting section to allow the second object to be unfolded and inclined to the first object.

One aspect is a rolling bearing with: a. at least an outer ring; b. at least an inner ring, wherein a raceway is defined by the arrangement of the outer ring and the inner ring; and c. at least three rolling elements wherein the rolling elements are arranged in the raceway, wherein at least one rolling element comprises at least an alloy as mentioned above.

The description relates to hinged devices, such as hinged computing devices. One example can include a first portion and a second portion. The example can also include a communication member spanning between the first and second portions and defining first and second parallel hinge pins. The first hinge pin can include a first cam follower that is received in a first multi-lobe cam of the first portion that forces the first portion away from the first hinge pin when the first and second portions are oriented at non-parallel orientations and allows the first portion to be biased toward the second hinge pin at parallel orientations.

An electronic device is provided. The electronic device includes a first housing including a first surface and a second surface, a second housing including a third surface and a fourth side, a folding portion, a flexible display disposed on the first surface and the third surface across the folding portion, and a hinge including a first planar portion disposed on the second surface, a second planar portion disposed on the fourth side, and a hinge center portion, wherein a first configuration where the folding portion is unfolded and the first housing and the second housing are parallel, and wherein a second configuration where the folding portion is folded and the first planar portion is at least partially inserted into the first housing and the second planar portion is at least partially inserted into the second housing and the first housing and the second housing are parallel.

A structure includes: a first component having a band-like shape and an elasticity for bending the first component in a first direction such that both ends of the first component approach each other; and a second component, coupled to the first component in a manner that the second component pivots about a rotational axis that lies along an edge in a longitudinal direction of the first component, and having an elasticity for bending the second component in a second direction opposite to the first direction when the first component and the second component are unfolded about the rotational axis.

A support structure for a bellows attached to a slide table, and which is capable of expanding and contracting in a movement direction of the slide table, includes support members that support the bellows, shafts disposed substantially in parallel with the movement direction of the slide table, and bushes that support the support member so as to be capable of moving in the movement direction of the slide table with respect to the shafts. Fluid bearings are formed by supplying a fluid between the bushes and the shafts.

A non-contacting spherical air bearing-based stable platform for use by a gravity gradiometer instrument (GGI) is provided by attaching a spherical ball-shaped bearing to a rotational stage of the GGI and integrating a concave spherical cup in the linear stage and mounting base assembly of the GGI which is fixedly attached to a host vehicle or platform. The spherical cup supports the spherical ball-shaped bearing on a thin cushion of air provided by a source of compressed air or gas at the concave surface of the spherical cup. The spherical ball-shaped bearing is supported, providing three degrees of rotational freedom of motion without the need for slip rings, flex capsules, races, or mechanical bearings, thereby reducing or eliminating gradient disturbance signals owing to parasitic torques and jitter in the output of the accelerometers of the GGI.

Timepiece oscillator, comprising a sprung balance assembly including a balance with a rim, which is returned by a balance spring and pivoted with respect to a structure, on a first side by a torsion wire, fixed by an anchoring element to the structure, and on a second side, opposite to the first side, by a contactless magnetic pivot, the balance comprising a first pole embedded with the balance and the torsion wire, this first pole having a symmetry with respect to the axis of the sprung balance assembly, and cooperating with a second pole comprised in the structure, for the magnetic suspension of the first pole, and to exert on the distal end of the torsion wire, opposite to this anchoring element, a magnetic force for tensioning the torsion wire.

An electronic device may include a housing and at least one coil carried by the housing. The electronic device may include a field member that includes a magnetic body having a shaft-receiving passageway therein, and at least one bearing within the shaft-receiving passageway. A shaft extends through the at least one bearing and coupled to the housing to permit reciprocal movement of the field member along the shaft and within the housing responsive to the at least one coil. A controller may be capable of powering the at least one coil to move the field member after a threshold period of non-movement.

An apparatus and method for inducing multiaxial vibrations to simulate an environment for transporting a stack of products is provided. A lower platform is provided for inducing uniaxial vibrations. A link is connected to the lower platform by a lower end of the link. The upper end of the link has a universal joint, through which the link is connected to an upper platform. The upper platform has a top surface, on which the stack of products can be placed. In operations, the uniaxial vibrations of the lower platform are transferred to the upper platform through the link and the universal joint, to induce pivotal movement of the upper platform with respect to the shaft of the link. As a result, multiaxial vibrations can be induced to the stack of products placed on the top surface of the upper platform.
