A packaging machine is for forming a product cavity in a web including a forming die box defining a recess into which the product cavity is formed. An insert is axially movable in the recess to thereby vary a depth of the recess. A variable depth mechanism selectively moves the insert to vary the depth of the recess. The packaging machine includes a latching mechanism that moves the forming die box into and between a first position in which the forming die box is spaced apart from the die box base and a second position in which the forming die box is supported by the die box base.

An absorbent insert of compressed matrix of absorbent material, including a filler dispersed therein to improve stiffness/rigidity of the insert and controls the absorbency of the compressed absorbent material. The insert is pre-shaped and sized for inserting into a tooth cavity, such as a pulp chamber or a root canal space. The compressed insert expands or swells upon absorbing fluid within the tooth cavity, so as to more completely dry the tooth cavity. The absorbent insert also serves as a substrate of an applicator for medical agent to be applied to a tooth cavity. The absorbent insert is provided (e.g., coated or impregnated) with a medical agent, which medical agent is released into the tooth cavity as the absorbent material absorbs fluid in the tooth cavity.

A method produces a fiber composite component for a motor vehicle. The method provides a semifinished fiber composite blank, wherein the semifinished fiber composite blank includes reinforcing fibers and a matrix material. The semifinished fiber composite blank is arranged between a first membrane and a second membrane. The semifinished fiber composite blank is shaped into a fiber composite molding by pressing the semifinished fiber composite blank together with the first membrane and the second membrane via a pressing device, and the fiber composite molding is consolidated.

Disclosed is an apparatus for manufacturing a microneedle patch, including: a silicon mold mounted on an upper surface to mold a material for the microneedle patch; a carrier of which the silicon mold is mounted on an inside of the upper surface; an upper block which is assembled with the carrier to form a chamber in which the material and the silicon mold are accommodated; an air cylinder which is connected to the upper surface of the upper block to transmit power so that the upper block descends to be assembled with the carrier and ascends to be separated from the carrier; and a pressing portion which is connected to a side surface of the upper block so as to press the chamber or ventilate the chamber while the upper block and the carrier are assembled with each other.

A method of forming an ice resistant surface includes determining, based at least in part on a desired pattern of frost formation, a vertex angle for a ridge that is to be formed on a substrate. The method also includes determining, based at least in part on the desired pattern of frost formation, a vertex height for the ridge that is to be formed on the substrate. The method further includes forming a plurality of ridges on the substrate, where each ridge in the plurality of ridges has the vertex angle and the vertex height.

A heat-resistant release sheet of the present disclosure is a sheet formed of a single-layer heat-resistant resin film having a thickness of 35 pm or less, wherein the sheet is disposed between a compression bonding target and a thermocompression head at the time of thermocompression-bonding the compression bonding target by the thermocompression head to prevent fixation between the compression bonding target and the thermocompression head, and a heat-resistant resin forming the heat-resistant resin film has a melting point of 310° C. or higher and/or a glass transition temperature of 210° C. or higher. A use temperature of this heat-resistant release sheet can be, for example, 250° C. or higher. The heat-resistant release sheet of the present disclosure can more reliably meet a demand for an increase in thermocompression bonding temperature.

A heat-resistant release sheet includes a heat-resistant release sheet to be disposed between a compression bonding target and a thermocompression head at the time of thermocompression-bonding the compression bonding target by the thermocompression head to prevent fixation between the compression bonding target and the thermocompression head, wherein surface hardness, as expressed in an indentation degree A.sub.300 given by an equation A.sub.300 (%)=(d.sub.300/t.sub.0)×100, of the heat-resistant release sheet at 300° C. is 15% or less, where to is a thickness of the heat-resistant release sheet at ordinary temperature (20° C.) and d.sub.300 is an indentation depth evaluated for the heat-resistant release sheet at 300° C. using a penetration probe by thermomechanical analysis (TMA) under the following measurement conditions: • Measurement mode: penetration mode, temperature rise measurement—Shape and tip diameter of penetration probe: columnar shape and 1 mmφ •Applied pressure: 1 MPa—Starting temperature and temperature increase rate: 20° C. and 10° C./min.

The heat-resistant release sheet of the present disclosure is a sheet including a sheet made of polytetrafluoroethylene (PTFE) or a modified PTFE, wherein the sheet is disposed between a compression bonding target and a thermocompression head at the time of thermocompression-bonding the compression bonding target by the thermocompression head to prevent fixation between the compression bonding target and the thermocompression head, and the content of a tetrafluoroethylene (TFE) unit in the modified PTFE is 99 mass % or more. The heat-resistant release sheet of the present disclosure can more reliably meet a demand for a shorter time (work time) required for thermocompression bonding.
