The embodiment provides a heat-sealing apparatus and a method of accurately controlling heat sealing temperature by measuring the temperature using a heat-sealing apparatus which heat-seals a pair of heat seal materials by nipping them between a pair of heating bodies. The method of heat-sealing includes mounting a cover material on the surface of at least one of the heating bodies to be in contact with the heat seal material, attaching a minute temperature sensor to the surface of the cover material on the side to be in contact with the heat seal material, and controlling temperature of welding face by the temperature detected by the minute temperature sensor, and an apparatus therefor.

The present invention relates to the field of biological sample testing technology, and in particular, to a testing system. The testing system includes a reagent reaction vessel and a test device. A reagent storage portion and a push rod movable relative to the reagent storage portion are packaged in the reagent reaction vessel, the reagent storage portion comprises at least one reagent containing cavity, and the reagent containing cavity is sealed by a sealing element; and the push rod is connected to the sealing element, and the push rod is used for cooperation with the test device to separate the sealing element from the reagent storage portion. The test device includes a test cassette, wherein an ejection rod is arranged in the test cassette, and the ejection rod cooperates with the push rod to separate the sealing element from the reagent storage portion. According to the present invention, when the reagent storage portion is inserted, the ejection rod can be quickly pushed to operate, and one operation completes multiple functions such as releasing the reagent, fixing the reagent reaction vessel, and focusing on a test area at the same time, thereby simplifying the reaction steps.

The present invention relates to a sealing device for a secondary battery. The sealing device is configured to seal a battery case accommodating an electrode assembly therein to manufacture the secondary battery, the sealing device including a sealing block configured to press a sealing portion of the battery case, a flatness adjusting part configured to adjust a flatness of a pressing surface of the sealing block, and a heater part configured to transfer heat to the sealing block to thermally fuse the sealing portion of the battery case when the sealing portion is pressed by the sealing block.

A portable assembly for securing a plastic fitting to a plastic pipe by employing fusion or thermal sealing is disclosed. The assembly is secured to the outer circumference of a plastic pipe at a desired location. The assembly can be secured at any longitudinal and lateral position along a plastic pipe. A heater heats both the pipe and the fitting to the point where they begin to melt. The heater is then removed and the fitting is pressed onto the surface of the pipe, thus fusing the fitting to the pipe. After cooling, the assembly is removed and the surface of the pipe within the interior of the fitting is drilled or removed. This now enables fluid within the pipe to be sent to the fitting and onto distribution lines which are connected to the fitting.

According to a method or an apparatus for fastening bristles in a bristle carrier (10) without using an anchor a heating (39) is provided in a tool part configured to transport the bristles. After inserting the bristles into anchoring openings (12) in the bristle carrier (10), the anchoring openings are closed by applying pressure.

A bag making and packaging machine includes a cutter fixed to a sealing member that cuts a laterally sealed portion of a film using pressure force with which a pair of sealing members sandwiches the film during lateral sealing. The bag making and packaging machine further includes a pair of sealing jaws, a knife, a pressurization mechanism, and a pressurization mechanism control part. The knife fixed to one sealing jaw, fusion-cuts the laterally sealed portion of the film. The pressurization mechanism exerts pressure force on one sealing jaw towards the other sealing jaw so that the pair of sealing jaws sandwiches and laterally seals the film therebetween, and the knife comes into contact with a laterally sealed portion and fusion-cuts the laterally sealed portion. The pressurization mechanism control part causes the pressurization mechanism to cease exerting pressure force based on error information pertaining to the film or the goods.

A biological sample reaction vessel comprising a reagent storage portion and a push rod movable relative to the reagent storage portion is provided. The reagent storage portion comprises at least one reagent containing cavity, and the reagent containing cavity is sealed by a sealing element; and the push rod is connected to the sealing element, and the push rod is used for cooperation with an external test device to separate the sealing element from the reagent storage portion. In reaction, the biological sample reaction vessel cooperates with a test cassette. By inserting the biological sample reaction vessel into the external device, the reagent in the reagent storage portion can be released rapidly.

A first aspect of the invention provides a method of joining a part to a composite component, the composite component comprising fibres impregnated with a matrix material, and the part comprising a plurality of projections, the method comprising: inserting the projections into the composite component; and pre-heating the projections before they are inserted into the composite component, so that the projections are at a higher temperature than the composite component as they are inserted into the composite component. The projections locally heat the matrix material of the composite component as they are pushed into the composite component. Increased temperature during insertion is advantageous as the reduced matrix viscosity, due to the increased temperature of the matrix, results in better consolidation of the fibres around the projections and minimises the distortion of the fibres. The composite component is only heated locally where heating is required, which removes the need to heat the entire composite component.

An apparatus for packaging a product comprises a packaging assembly to fix a film sheet to a support. The packaging assembly includes a lower tool having seats for receiving the support and an upper tool facing the lower tool and comprising a film holding plate for holding the film sheet. The film holding plate has an active surface for receiving the film sheet, where the upper and lower tools cooperating to define a packaging chamber. The packaging assembly is open to receive the film sheet in a first operating condition and is hermetically closed in a second operating condition. The film holding plate has a lateral surface extending substantially perpendicular to a plane defined by the active surface, the film holding plate comprising ejectors arranged in the lateral surface for ejecting a stream of gas substantially parallel to said plane and substantially away from a center of the active surface.
