Provided is a jig having a structure that differs from conventional jigs and enables flat plates to be bonded while suppressing an air bubble formation. A flat-plate bonding jig is provided with the following: a first surface; a second surface that is on the opposite side of the first surface, has a plurality of suction holes for sucking a flat-plate, and is curved outward in a substantially arc shape; a main body connecting the first surface and the second surface; and a communication means that is disposed in the main body and allows the suction holes to communicate with a suction means.

A method for fulfilling a plurality of orders for goods at a provider location comprises obtaining an arrival sequence estimate for each of a plurality of users indicating the sequence in which the users are expected to arrive, and organizing completed orders according to the arrival sequence estimate. The arrival sequence estimate may be obtained by ordering users according to their respective radial distances from a target, and may also be used to schedule processing of the orders. Alternatively, arrival estimates for when each of the users is expected to arrive may be used to schedule processing of the orders. A dynamic arrival estimate may be obtained based on an expected travel path toward the destination during a first trip portion comprising travel within a constrained travel path network, and based on radial distance from the destination during a second trip portion subsequent to the first trip portion.

A positioning device includes a support member configured to carry a workpiece, a plurality of pins positioned on the support member, and a plurality of telescoping mechanisms positioned on the support member. Each of the telescoping mechanisms comprises a driving member and a rotating member connected to the driving member. The positioning pins slidably pass through the support member and are pivotably connected to an opposite end of the rotating member. The rotating member rotates relative to the support member via the driving member to adjust an extending length of the positioning pins relative to the support member.

A vacuum device for a material handling system includes a vacuum device body and a sealing element. The vacuum device body has a vacuum passageway in which a vacuum is generated in response to activation of a pressurized air supply that forces pressurized air through a venturi device. The sealing element moves to a sealing position to substantially seal the vacuum passageway when the air supply is activated, and is urged toward the sealing position via pressurized air that is diverted from an inlet of the vacuum device to the sealing element. The sealing element moves to substantially vent the vacuum passageway when the air supply is deactivated. The vacuum passageway may be in fluid communication with a vacuum cup, which seals against the object when the sealing element is at the sealing position and the vacuum generating device generates at least a partial vacuum in the vacuum. passageway.

The invention relates to hand tools of knife sharpening, especially for sharpening of kitchen knifes, namely relates to angle guides for knife sharpening. This angle guide has a removably attachable body that is put on a sharpening rod through a hole going through the body, which has the ability to move back and forth on the rod. The body has guiding cutouts for the blade of a knife that allow to maintain the desired angle against the sharpening rod during the sharpening procedure. At least one pair of cutouts with inclined narrowing cavities are formed in the body on its opposing sides in opposing directions, which allows to alternate between the sides of the blade during the sharpening process and in this way much less burr is produced.

Methods of producing a glass sheet each comprise the step of creating a vacuum to force the entire lateral portion of the glass ribbon to engage an anvil portion of a breaking device in the elastic zone. The vacuum is provided by a plurality of pressure zones that are operated independent from one another, wherein each pressure zone is provided with a set of suction cups. In further examples, glass ribbon breaking devices each include a plurality of pressure zones that are configured to be operated independent from one another with each pressure zone being provided with set of suction cups.

Disclosed is a vacuum chuck and a method for securing a warped semiconductor substrate during a semiconductor manufacturing process so as to improve its flatness during a semiconductor manufacturing process. For example, a semiconductor manufacturing system includes: a vacuum chuck configured to hold a substrate, wherein the vacuum chuck comprises, a plurality of vacuum grooves located on a top surface of the vacuum chuck, wherein the top surface is configured to face the substrate; and a plurality of flexible seal rings disposed on the vacuum chuck and extending outwardly from the top surface, wherein the plurality of flexible seal rings are configured to directly contact a bottom surface of the substrate and in adjacent to the plurality of vacuum grooves so as to form a vacuum seal between the substrate and the vacuum chuck, and wherein each of the plurality of flexible seal rings has a zigzag cross section.

Method and apparatus for sharpening a cutting edge of a cutting tool, such as a kitchen knife. A fixture secures opposing sides of a blade of the cutting tool and includes a main body and hinged first and second clamping jaws each having a clamping end adapted to compressingly engage a respective side of the blade. A guide coupled to the main body has converging support surfaces to contactingly engage a back edge (spine) of the blade opposite the cutting edge to center the blade along a central plane of the fixture. A retraction mechanism establishes a clamping force upon each of the respective sides of the blade via the clamping jaws. Further embodiments include a base assembly adapted to receive the fixture, and a swing arm style abrasive assembly to carry out a sharpening operation upon the cutting edge.

An intermediate partition plate positioning apparatus and battery module assembling equipment are provided. The intermediate partition plate positioning apparatus includes: a supporting mechanism; a first adjusting mechanism, connected to the supporting mechanism, and configured to drive the supporting mechanism to move along a vertical direction; and a second adjusting mechanism. The second adjusting mechanism is located on at least one side of the supporting mechanism along a first horizontal direction. The second adjusting mechanism includes a clamping portion and a driving portion. The clamping portion is connected to the supporting mechanism. The driving portion is able to drive the clamping portion to move so that the clamping portion clamps the intermediate partition plate from two sides of the intermediate partition plate along a second horizontal direction. The first horizontal direction intersects the second horizontal direction.
