A split axis stage architecture is implemented as a multiple stage positioning system that is capable of vibrationally and thermally stable material transport at high speed and rates of acceleration. A split axis design decouples stage motion along two perpendicular axes lying in separate, parallel planes. A dimensionally stable substrate in the form of a granite, or other stone slab, or of ceramic material or cast iron, is used as the base for lower and upper stages. The substrate is precisely cut (“lapped”) such that its upper and lower stage surface portions are flat and parallel to each other.

A rigid support structure allows for faster and more accurate positioning of axially adjustable optical components in a laser processing system.

A compression resistant isolator disposed between a direct fuel injector and a cylinder head of an internal combustion engine provides thermal, or thermal and vibrational isolation therebetween. A plurality of radially spaced rigid axial support members provide axial load support to maintain proper direct fuel injector positioning within the cylinder head bore. Spaces formed between the rigid axial support members may have isolation materials positioned therein. The implementation of the isolator may reduce the operating temperature of a fuel injector for direct injection, which is critical to avoid injector tip plugging.

An image-forming device includes a photosensitive drum, a transfer roller, a guide plate for guiding the paper toward the photosensitive drum, and a sponge fixed to the bottom surface of the guide plate. The sponge is softer than the guide plate, so that it can absorb vibrations in the guide plate when the trailing edge of the paper leaves the guide plate.

Apparatus for joining a first conduit to a second conduit comprising a first coupler for attachment to an end of the first conduit, a second coupler for attachment to an end of the second conduit and for engagement to the first coupler, and a snap-fit fastener for fastening the first coupler to the second coupler. The snap-fit fastener is arranged in at least two portions to fit around the periphery of the first and second couplers when the first and second couplers are engaged.

A fuel feed apparatus accommodates a sub tank. The sub tank includes a pump module The pump module generates vibration, and is supported by a supporting member and a suction filter. The suction filter is covered with a nonwoven fabric. The nonwoven fabric is used as an additional filter for removing debris in fuel drawn by the pump module. The supporting member and the nonwoven fabric have resilience. The pump module is mounted on the sub tank via the supporting member and the non woven fabric. Therefore, vibration of the pump module is not apt to be transmitted to the sub tank. Additionally, the supporting member need not to be rigidly formed, so that the supporting member can be manufactured easily.

The invention relates to a liquid static pressure central support of a machine tool for processing shaft-type parts, which solves the problem that the bearing precision in the precision machining of the shaft-type parts is insufficient. The central support is characterized in that a lower bearing bush is arranged on the central support, an upper bearing bush is arranged on the inner lateral surface of an upper gland in the radial direction, bearing grooves are formed on the working planes of the upper bearing bush and the lower bearing bush, and an oil returning groove is formed between adjacent bearing grooves; arc oil grooves are formed on the back of the upper bearing bush and the lower bearing bush; orifices are formed on the bearing grooves, and the orifices are communicated with the bearing grooves and the arc oil grooves; a lower oil inlet is formed on the central support; upper semi-end covers are arranged on both lateral surfaces of the upper gland in the axial direction respectively, and lower semi-end-covers are arranged on both lateral surfaces of the lower concave semicircular surface of the central support in the axial direction respectively.
