In an image-displaying screen that is formed of a plurality of plates having lens structure, the reliability of the fixing between the plurality of plates is enhanced. A screen that displays an image includes a lenticular lens plate and a Fresnel lens plate that is fixed to the lenticular lens plate by thermal welding. Because the lenticular lens plate and the Fresnel lens plate are thus fixed together by thermal welding, the fixing strength between the lenticular lens plate and the Fresnel lens plate is not deteriorated by repeated distortion of the welded portion, as would be caused by temperature variations etc. when a welding agent is used to fix them. This enhances the reliability of the fixing between the lens plates.

A method of sealing parts of a plastic capsule by forming a weld seam in an overlapping region of the parts of the capsule, wherein the capsule comprises a capsule cap having an open end and a capsule body having an open end, the method comprising: (a) holding the capsule cap and the capsule body in a capsule holder comprising a first holding part and a second holding part which can be guided synchronously with one another, wherein the first holding part interlockingly surrounds the capsule cap and the second holding part interlockingly surrounds the capsule body; (b) closing the capsule holder holding the capsule cap and the capsule body so that the open end of the capsule cap and the open end of the capsule body form a sealed cavity therebetween and form an overlapping region, wherein the overlapping region is not covered by the capsule holder, to obtain a closed capsule; and (c) welding the closed capsule using an energy beam of hot gas or laser light on the overlapping region by forming the weld seam thereon. The capsules produced by the process according to the invention are disposable capsules and preferably contain a single dose of a pharmaceutical formulation in the form of a powder or liquid suitable for inhalation and are suitable, by their form and function, for use in powder inhalers or liquid nebulizers for producing aerosols. Aerosols thus produced can be inhaled, for example, in order to administer a pharmaceutical formulation to the lungs.

The object is to provide a writing instrument and a welding method of a writing point assembly as well as writing instrument parts connecting structure and connecting method, wherein the writing point assembly and an ink tube or/and a holder can be welded appropriately at a necessary area only without using ultrasonic waves, so as to be able to prevent dislodging of the writing point assembly, ink leakage and the like. The rear end part, of a metallic writing point assembly as a part of a writing instrument, which is inserted into a joint, is heated at the predetermined area (at least the fitted area in contact with the front end part of the joint), so as to weld the predetermined area of the writing point assembly to the surrounding part of the joint.
摘要:
A method is proposed for welding a first component part to a second component part, the energy to melt melting regions being supplied by a laser beam. In this context, the laser beam is directed through the first component part, which is made of a nonabsorbing material, to the second component part. The second component part is made of a material which strongly absorbs laser beam. At least one stop is provided outside melting regions.

A multilayer insulation having a plurality of layers laminated together, and a plurality of depressions positioned proximate to edges of the multilayer insulation, the plurality of depressions forming insulated tabs on the multilayer insulation. An adhesive layer may be provided on one or more insulated tabs. In one embodiment, the depressions are positioned and sized to allow folding of the insulated tabs to form an integrated spacer. In another embodiment, the depressions are positioned and sized to allow receiving of an insulated tab of an adjacent insulation. In this regard, the depressions and the insulated tabs are preferably sized the same width to allow interlocking of the multilayer insulation to an adjacent multilayer insulation. A method of installing insulation is also described for providing an integrated spacer or interlocking adjacent insulation pieces. A method of manufacturing insulation with a depression that defines an insulated tab is also described.
