A manipulator for servicing tubes extending through a tube sheet having three major components: a base member, a block member, and a foot member. The base member has a holder for supporting tooling or inspection devices. The base member also has at least one gripper for releasably gripping a tube extending through the tube sheet. The block member is connected to the base member for linear movement and rotation relative to the base member. The foot member is connected to the block member for linear movement relative to the block member. The foot member has at least one, and preferably two grippers, for releasably gripping a tube extending through the tube sheet. The manipulator supports itself using the two sets of expandable and translatable grippers that anchor into the tube ends and can move from tube to tube by alternately engaging each set of grippers.

A method and apparatus for reducing speckle during inspection of articles used in the manufacture of semiconductor devices, including wafers, masks, photomasks, and reticles. The coherence of a light beam output by a coherent light source, such as a pulsed laser, is reduced by disposing elements in a light path. Examples of such elements include optical fiber bundles; optical light guides; optical gratings; an integrating sphere; and an acousto-optic modulator. These various elements may be combined as desired, such that light beams output by the element combinations have optical path length differences that are greater than a coherence length of the light beam output by the coherent light source.

A linear drive portion is fixed to a piston. A nut portion and a screw portion relatively rotate, and a direction of action of driving force is converted between a rotational direction and a linear direction. The piston is installed within a case. The inner circumference of a piston sliding portion fixed within the case slidably supports the outer circumference of the piston. The nut portion is displaced with the piston, and the screw portion rotates in conjunction with a rotational drive portion. The piston is installed so as to be able to slide in the axial direction of the case with respect to the piston sliding portion. The axis of the piston and the central position of the inner circumference of the piston sliding portion are set to be eccentric with respect to the axis of the screw portion and the nut portion.

The invention relates to a method and a device for joint denitrifying by denitrification and anaerobic ammonia oxidation embedding particles, and belongs to the field of sewage. The method comprises the following steps of respectively embedding a WPU (water-borne polyurethane) material by separated denitrification bacteria and anaerobic ammonia oxidation bacteria, putting the denitrification embedding particles into a flow-separated ball, putting anaerobic ammonia oxidation embedding particles into a Pall ring or into water in a floating state, and setting the denitrification embedding particles and the anaerobic ammonia oxidation embedding particles into an incomplete mixing state.

A vibration isolating functional member 16 is formed of an inner cylinder 1, an outer cylinder 2, and a vibration isolating rubber 3. Thereafter an end face of a flange 10 of the outer cylinder 2 is joined with a bracket side connecting surface 15 of a bracket 4 and the joint portion thereof is laser welded. In this time, the outer peripheral end face of the flange 10 as the joining portion projects toward a position apart from the vibration isolating rubber 3 such as giving no thermal influence to the vibration isolating rubber 3. This position to give no thermal influence to the rubber is determined by an experiment based on a welded material, thickness thereof, laser welding conditions (such as melting depth, output power and welding speed), surface temperature limit of the rubber and so on.
