The present invention provides a methacrylic resin composition for non-contact hot plate welding comprising a methacrylic resin comprising 80 to 99.9% by mass of a methacrylic acid ester monomer unit and 0.1 to 20% by mass of a unit of at least one additional vinyl monomer copolymerizable with the methacrylic acid ester monomer, wherein the methacrylic resin composition has a melt flow rate (MFR) of 2.5 g/10 min or lower at 230° C. at a load of 3.8 kg.

An object of the present invention is to provide a thin volume hologram sheet to be embedded sufficiently resistant to a mechanical stress such as a stress including a tensile stress, a shear stress and a compression stress at the time of processing even under a heating condition, a forgery prevention paper and a card using the same. The object is achieved by providing a volume hologram sheet to be embedded comprising a volume hologram layer, and a substrate disposed only on one side surface of the volume hologram layer using an adhesion means, wherein a peeling strength of the volume hologram layer and the substrate is 25 gf/25 mm or more.

An apparatus for quality assessment of a sealing section of a package for food products. The package includes at least a robustness layer and a plastic layer. The sealing section is formed by holding a first section and a second section of the package against each other while providing heat such that the plastic layer of the first and second section melt and the first and second section adhere to each other. The apparatus includes a sample holder arranged for fixating a sample including the sealing section of the package. At least part of the sample holder is transparent, a magnification device arranged on a first side of the sample holder, and an illumination device arranged on a second side of the sample holder. Light is provided to the magnification device through the sample holder The first and second side are opposite sides of the sample holder.

Embodiments of the invention relate to a sealing element for thermally connecting thermoplastic materials along a bent or curved contour, including a plurality of flat support substrates with a front face and a rear face, the substrates having at least one heating element on the front face, and including a contoured element which has a front face in the shape of the contour to be sealed, wherein the rear face of the support substrates is secured to the front face of the contoured element and/or the front face of the support substrates is secured to the rear face of the contoured element.

A generator injection tool is provided. The generator injection tool injects an adhesive into a generator that includes a rotor positioned within a stator having a stator vent, the stator and rotor having a gap therebetween. The generator injection tool includes a first carriage sized to fit within the gap, a tube, a first motor, a controller, and an adhesive source. An end of the tube is movable between a first position in which the end is outside of the stator vent and a second position within the stator vent. The first motor is operable to move the tube between the first position and the second position. The controller is operable to selectively activate the first motor to position the end of the tube within the stator vent. The adhesive source moves the adhesive through the tube end to inject a portion of the adhesive into the stator vent.
