The embodiment includes: a planar graphite heater; a clamp device that moves the graphite heater, which is arranged between a first bonding surface W1a of a first composite material member and a second bonding surface of a second composite material member facing the first bonding surface, in a traveling direction with the graphite heater being in contact with the first bonding surface and the second bonding surface; and a control unit that controls the graphite heater to heat the first bonding surface and the second bonding surface while the graphite heater is in contact with the first bonding surface and the second bonding surface.

An ultrasonic bonding apparatus includes a stage having an upper surface on a plane defined by a first direction and a second direction crossing the first direction, a head part spaced apart from the stage in a third direction crossing the first direction and the second direction, a first ultrasonic generator which vibrates in a direction parallel to the first direction, and a second ultrasonic generator which vibrates in a direction parallel to the third direction, where each of the first ultrasonic generator and the second ultrasonic generator may be coupled to the stage or the head part.

A method of manufacturing magnets and a method of manufacturing a rotor are provided. An intermediate member includes a sheet and magnet bodies. The sheet includes a first sheet surface and a second sheet surface on a side opposite to the first sheet surface. The magnet bodies are located on the first sheet surface. A first die is made of an elastic material having an elastic coefficient lower than the elastic coefficient of the magnet bodies. The intermediate member is arranged between the first die and a second die such that the second sheet surface of the sheet faces the first die. The first die and the second die hold the intermediate member in between. Accordingly, the sheet is cut at positions between adjacent ones of the magnet bodies.

The present disclosure provides a screen protector pasting assisting device for automobiles, including a body structure, wherein the body structure includes two long edges and two short edges, each of the long edges including a first limit portion, a first sink portion, a second sink portion, a first sink portion, and a first limit portion, one ends of the two first limit portions being respectively connected to the two short edges. The second sink portion is provided with a positioning protrusion. The device features a simple structure and convenient operations, and is suitable for use by a non-professional person in screen protector pasting, thereby achieving a strong practicability.

A method for joining at least two joining partners includes performing a plurality of ultrasonic joining operations in direct succession, wherein performing an individual ultrasonic joining operation includes, with a second joining tool, applying pressure to a second joining partner arranged adjacent to a first joining partner, thereby pressing the second joining partner against the first joining partner, and, with the second joining tool, applying high-frequency ultrasonic vibrations to the joining partners. The method further includes, during at least one intermediate time interval between two directly successive ultrasonic joining operations, at least one of actively cooling and heating the second joining tool. The second joining tool is heated or cooled by a temperature unit. The temperature unit is inactive during each of the plurality of ultrasonic joining operations.

The invention relates to a method for producing a test body (30) for mechanically destructively testing a materially bonded joining connection, wherein the method comprises the following steps: providing an areal fiber composite substrate formed from a fiber composite material which has a fiber material and matrix material in which the fiber material is embedded, applying at least one test fabric and an adhesive to a substrate surface of the areal fiber composite substrate, and curing the adhesive, and therefore a materially bonded joining connection is produced between the test fabric and the substrate surface by way of the cured adhesive,
wherein a Dutch-weave fabric and/or a square-mesh fabric is provided as the test fabric.

An ultrasonic welder includes, among other things, a sonotrode, a sleeve that is arranged at least partially around the sonotrode, and a biasing assembly that acts on the sleeve and is configured to urge the sleeve to an extended position relative to the sonotrode in response to a biasing force. The sleeve is configured to move from the extended position to a clamping position relative to the sonotrode in response to engagement with a workpiece which opposes the biasing force.

The present invention relates to a method for manufacturing non-slip socks, which arranges and presses a fabric to which a grapping member is bonded at the inside of the sock and then arranges and presses the fabric to which the grapping member is bonded at the outside of the sock. Here, accuracy of positions of the grapping members at the inside and the outside of the sock may increase by using a unit for guiding a position of the fabric, and productivity may improve.

The present invention relates to an apparatus for manufacturing non-slip socks, in which a groove is formed in a mold rotating along a rotation table, and which includes a guide device at one side thereof to arrange fabrics at an exact position on the inside and the outside of the sock and maintain a state in which grapping members at the inside and the outside of the sock are exactly alternately arranged.
