A manufacturing method is provided for a fluid control apparatus, in which the flow of a fluid is controlled by bringing a diaphragm valve element into contact with or separating the diaphragm valve element from a valve seat. The diaphragm valve element may be a joint body that is a combination of (a) a seat member that makes contact with the valve seat and (b) a body member. The joint body is formed by machining a material joint body obtained by welding together a seat-member material which is a material for the seat member and a body member material which is a material for the body member. The welding is performed on contact faces of the seat-member material and the body-member material of the material joint body in a range wider than contact faces of the seat member and the body member of the joint body.

A bonding device for charging a liquid material into a space between plate-shaped members for bonding them together in situ, in which the liquid material may be prevented from exuding from the space between the plate-shaped members. The bonding device includes pair retaining base members for retaining the pair plate-shaped members facing each other, and a retaining base member movement unit for causing movement of the retaining base members towards and away from each other. The bonding device also includes an illumination unit that illuminates curing light to a photo-curable liquid material charged between the pair plate-shaped members held by the pair retaining base members, and a sensor that detects the wetting spreading state of the liquid material charged between the pair plate-shaped members.

Optical disc manufacturing apparatus of the present invention comprises a nozzle for ejecting TV curable cationic composition, ultraviolet radiation means for radiating ultraviolet rays while the UV curable cationic composition dropping from the nozzle reaches a disc substrate; and superimposing means for superimposing the two disc substrates one upon another by allowing planes onto which the UV curable cationic composition is dropped to be faced. To allow the UV curable cationic composition to spread between the two disc substrates superimposed by the superimposing means: a statically placing plane for placing the disc should be provided. A stacking means for stacking the plurality of discs and rigid disc placing means for placing a rigid disc having a flat plane on the disc in the course of stacking the plurality of discs should be provided.

A reflective hood system for heat-shrinking a film onto an open-topped container includes a radiant energy source located above the mouth of the container, and a reflective hood which serves to concentrate the energy from the a radiant energy source located above the mouth of the container and redirect energy radially inwardly onto the area of the film which is to be shrunk. A reflective hood system may also include a reflective shield located at or near an opening in the reflective hood above the mouth of the container.

An adhesive curing apparatus and method utilizes the end of a tube or optical fiber extending from a UV light source. The tube end is inserted into the mounting hole in the side of a pivot assembly. The tube projects concentrated UV light into the interior of the assembly for curing the adhesive used to bond the bearings to the shaft and the housing. The tip at the end of the tube has beam splitting mirrors or prisms to distribute the UV light more effectively. The interior of the assembly, including the outer surface of the shaft and the inner surface of the housing are smooth, polished metal to further enhance the intensity of the light incident on the adhesive.
摘要:
A packaging film which shrinks to form at least part of a package when exposed to heat. The packaging film includes a thin film substrate that contracts or shrinks when heated and which is substantially transparent to radiant energy. The film also includes a susceptor material carried by the film that is sufficiently opaque to radiant energy to absorb and transfer to the substrate enough heat energy to cause the substrate to shrink, when the film is exposed to a source of radiant energy. In one embodiment the packaging film takes the form of lids of beverage containers.

A device for curing an obscured photosetting compound in a subassembly part has a base for supporting the assembly and a plate mounted to the base. The plate has a lens that concentrates UV light into a narrow slit in the assembly to quickly cure the compound. In an alternate version, the plate has a parabolic opening with a mirrored surface for gathering the UV light. A third version of the invention uses a rotatable fixture to position the assembly beneath a UV laser light source to cure the compound.
摘要:
A method of manufacturing an optical disc which is capable of speeding up the curing of an adhesive and capable of reducing an area or space occupied by a curing unit when manufacturing an optical disc, and a method of manufacturing an optical disc which is not susceptible to heat from a curing unit or a UV irradiation unit while an adhesive is cured. The method of manufacturing an optical disc includes a step of supplying lower and upper disc substrates, a step of spreading an adhesive between the lower and upper discs, and a step of irradiating the adhesive spread between the lower and upper discs with UV, wherein the irradiation step is performed on a turntable.

A process for assembling a disk cartridge is disclosed. The process includes the steps of snapping a top shell half of the disk cartridge over a bottom shell half of the disk cartridge; adjusting the shell halves until the shell halves are in abutment contact with each other at a weld site; and directing an energy beam at the weld site until a portion of the top shell half and a portion of the bottom shell half fuse so that the top shell half is fixed to the bottom shell half. The process is repeated for each of a plurality of weld sites located on the perimeter of the disk cartridge. A process for assembling a disk cartridge is disclosed in which an energy beam is split into a plurality of split energy beams. The plurality of split energy beams are focused on a plurality of weld sites until a portion of the top shell half and a portion of the bottom shell half fuse so that the top shell half is fixed to the bottom shell half. A disk cartridge prepared by either of the above described processes is also disclosed.
