The invention relates to a suction device (12) comprising a valve housing (18), a flexible partition wall (28) which runs in such a way that a control space (30) extends on one side and an intake side (21) lies on the other side, wherein the control space (30) is connected to the intake side (21) via a throttle passage (38), wherein the throttle passage (38) is formed in such a way that a flow resistance for flows is defined by the throttle passage (38) in such a way that, in the case of free suction, a negative pressure in relation to the intake side occurs in the control space (30) on account of the flow resistance. A sealing protrusion (44) protruding into the interior of the control space (30) and an associated seal seat (50) within the control space (30) are provided, wherein the sealing protrusion (44) and seal seat (50) are formed in such a way that, when the sealing protrusion (44) is placed against the seal seat (50), the flow path (40) through the throttle passage (38) into the control space (30) is interrupted within the control space (30).

A universal object holding mechanism for holding three-dimensional objects for printing thereon uses multiple conformable balls mounted within a pattern of holes in a two part back plate. The multiple conformable balls are pressed into an object, which in turn, is pressed against a datum surface that represents desired spacing away from print heads. Vacuum is applied to the multiple conformable balls which grip the object. The multiple conformable balls are filled with particulates that cause the multiple conformable balls to become rigid when the vacuum is applied. This contributes to keeping the object from moving when it is being moved past a print head.

A vehicle windshield triangulation assembly (11), and triangulation method using it with a railing (22) fixed to a vehicle (16) via sliding/rotatable/orientation-adjustable/height-adjustable mounts (18). A sliding seat (21) on railing (22) receives the telescoping end (1) of assembly (11) after its two connected 360-degree rotation swivel clamps (7), each having a suction cup (8), are secured against the old windshield's (17) exterior surface. Assembly (11) triangulation transfers to a new/replacement windshield (17) by releasing suction cups (8) and pairing them in the same manner with the new/replacement windshield (17), and making needed height adjustment to a top stop (12/13) and the swivel clamp (7) remote from top stop (12/13). The telescoping end (1) of assembly (11) is then engaged with sliding seat (21), allowing one person to easily and accurately move the new windshield (17) into the same positioning of the old windshield (17). This triangulation method accommodates windshields (17) having any size and curvature, and installation of windshields (17) occurs without a dry set step, measuring, templating, or educated guessing being required.

A machining support configured to reduce spring back of a sheet following a machining operation on the sheet is presented. The machining support comprises a porous material with a plurality of surfaces including a support surface having a contour configured to contact and support the sheet; sealing material covering each of the plurality of surfaces except the support surface; and a vacuum port configured to provide a vacuum to the porous material.

The present invention relates to a conductive porous ceramic substrate and a method of manufacturing the same, and more particularly to a conductive porous ceramic substrate, in which a porous ceramic substrate used as a chuck or stage for fixing a thin semiconductor wafer substrate or display substrate through vacuum adsorption is imparted with antistatic performance so as to prevent the generation of static electricity, and a method of manufacturing the same.

In order to respond flexibly to various processing modes, such as forming curved surface shapes, when cutting a workpiece using a wire saw, this wire saw device (1) is provided with: a single robot arm (2) that is capable of moving freely by means of multi-axis control; a wire saw unit (3) that is detachably connected to the robot arm (2) via a tool changer (7); a wire (8) that spans a plurality of pulleys supported within the wire saw unit (3); and a workpiece cutting zone (20) that is established between the pulleys. The workpiece is cut to a prescribed shape by moving the robot arm (2) in a preset direction while running the wire (8) of the wire saw unit (3) and pressing the wire (8) against the supported workpiece.

A holding apparatus, in particular a chuck, for a substrate comprises a main body with a upper side, a carrier element arranged in a recess of the main body so as to be vertically movable such that it can be adjusted between a protruding loading position and a retracted clamping position, the carrier element comprising a support surface for placement of the substrate. The support surface has a smaller diameter than the main body. A lifting element lifts the carrier element to the loading position. The carrier element seals the recess such that a sealed cavity is provided between the main body and the carrier element, which cavity can have a negative pressure applied thereto which counteracts the effect of the lifting element.

A support device (10) includes a substrate receiving region. The support device (10) includes a support body (110) shaped as a pattern having an array of openings (130). The support body (110) is a sparse structure wherein a joint area of the openings of the array of openings (130) is 40% or more of the area of the substrate receiving region. The support body (110) includes one or more suction openings (140) configured to be in fluid communication with a vacuum source arrangement.

A nozzle jig for sucking products includes a nozzle body and a suction head. The nozzle body includes at least one air channel. The suction head includes a mounting portion and the suction portion. The mounting portion includes a connecting hole. The suction portion includes at least one suction hole and at least one exhaust groove. The suction portion is connected to the nozzle body through the mounting portion. The at least one suction hole, the connecting hole, and the at least one air channel communicate in that sequence. Each of the at least one exhaust groove extends inwardly from a periphery of the suction portion.

This air control device for mounter is to solve a problem of realizing an air control device for a mounter capable of providing a secured holding state by a nozzle without damaging a part by adjusting, during vacuum suction, an amount of air to be drawn suitably for the part and the nozzle. This air control device for mounter is configured such that a nozzle n detachably attached to a head module HM of a mounter is connected to a negative pressure region, and a part is suctioned at a distal end of the nozzle n. The head module HM is mounted with a variable throttle mechanism 4, and by using the variable throttle mechanism 4, an amount of air to be drawn into the negative pressure region from the nozzle is adjustable.
