摘要:
To obtain a close-contact multi-layer type diffractive optical element having a homogeneous high-refractive-index and low-dispersion resin layer, an acrylate-terminated oligomer, obtained by allowing excess bifunctional acrylate to react with bifunctional thiol, is used as a resin precursor for the high-refractive-index and low-dispersion resin layer.

A spherical bearing assembly manufacturing apparatus and its manufacturing method is disclosed. The spherical bearing that houses and supports a spherical journal is manufactured with fiber reinforced composite as a material. The spherical bearing assembly manufacturing apparatus consists of a mold, plunger, and first and second grippers. The mold has a cavity for molding fiber reinforced composite into a spherical bearing, and a first press surface for supporting fiber reinforced composite, and a first guide hole communicated with the cavity. The plunger has a second press surface for molding the fiber reinforced composite housed in the cavity into a spherical bearing, and a second guide hole formed in the center of the second press surface. In the first gripper is formed a hole in which the edge on one end of the spherical journal is housed. In the second gripper is formed a recessed portion in which the edge on the other end of the spherical journal is housed.

A closure device includes a top wall, a skirt depending from the top wall, and a plurality of pads arranged circumferentially on the top wall, the pads extending into a space formed by the top wall and the skirt, the spaced pads configured to vent gas between adjacent pairs of pads during molding of a liner material against the top wall. A method of forming a liner in a closure device includes applying a moldable material to a top wall of the closure device, engaging a face of a punch of a liner-molding device with pads arranged on the top wall, the pads extending into a space formed by the top wall and a skirt depending from the top wall, compressing the moldable material by the punch against the top wall to form the liner, and venting gas between adjacent pairs of pads during the compressing step.

An electrical device and method of making same is provided wherein a chip or other electrical component is embedded in a substrate. The substrate may be a thermoplastic material capable of deforming around the chip and at least partially encasing the chip when heat and/or pressure is applied to the substrate. Electromagnetic radiation such a near infrared radiation can be used to heat the substrate. The substrate may include a compressible layer that can be compressed and/or crushed to form a recess into which the chip can be inserted. Once embedded, the chip or electrical component is secured by the substrate and may be coupled to another electrical component. A method of making an RFID transponder is also provided wherein an RFID chip is embedded in a substrate using heat and/or pressure, an antenna structure is applied to the substrate, and the RFID chip and antenna structure are coupled together.

A gasket is capable of providing an excellent slidabiity and holding its sealability without applying lubricant and a gasket that can prevent a resin film from being peeled off of a gasket body and prevent the generation of a molding defect such as pinholes. The gasket can be installed slidably in a outer tube of a syringe, including a gasket body and a resin film formed of a material lower in coefficient of friction than a material of the gasket body, which covers at least an outer periphery of the gasket body, in which when a surface roughness of the resin film on the outer tube side is defined as Ra1 and a surface roughness of the resin film on the gasket body side is defined as Ra2, a relationship of 1.5 Ra1≦Ra2 is satisfied.

摘要:
A method of fabricating a stamping mold suitable for use in the formation of a tapered waveguide structure includes defining a stamping pattern upon the surface of a silicon wafer, and removing portions of the silicon wafer surface in accordance with the stamped pattern, thereby creating tapered vertical surfaces within the wafer.
摘要:
A method and apparatus for molding a plate having highly detailed surface features from a thermosetting resin with a high concentration of a filler such as graphite. The method an apparatus provides for the formation of a preform of casting material and the placement of the material in a cavity mold which is precisely temperature controlled, has vacuum assist operating throughout the molding operation. The molding pressure is rapidly increased to flow the material through the molding cavity prior to the onset of curing and uniquely positioned ejector pins are provided for removal of the molded plate without damage to the detailed surface features.

In a temperature controlled segmented die for forming pressed containers such as plates, trays, bowls or the like including a die segment with a forming surface and an outer movable annular die member there is provided a side mounted temperature probe which extends laterally around the movable annular die member and toward the forming surface of the die segment. The apparatus is particularly useful for forming pressed paperboard containers such as paper plates.
摘要:
A multi-point thin portion compression molding method and apparatus in which a plurality of ultra thin portions can be formed by compression molding. Mold apparatuses are opened/close to each other to form a cavity space having a molded material therebetween, at least one movable telescopic member passes through one metal mold and protrudes toward the other metal mold, the central and outer periphery of the telescopic member are provided with vent portions, and recess portions are formed on the metal mold contacting the vent portions to allow molten resin to escape, and the recess portions adjust a pressure applied to the cavity space by the compressing operation of the telescopic member.
摘要:
Activity or craft apparatus and method for simply, quickly and inexpensively creating a thin lithophane-like pictorial work that provides a picture or image when light passes through the work from the rear. The work is formed from a formable translucent material. One form of illustrated apparatus comprises a generally closed container having a transparent see-through front wall. On the rearwardly inwardly facing side of the wall it has a contoured forming surface that is the reverse image of a desired contoured recessed picture-providing surface of a desired lithophane-type work. The illustrated container also has a second or rear wall that is generally parallel to and closely spaced from the front wall. The rear wall is translucent or transparent so that the light can pass through it from the rear. When the container is generally filled with translucent formable material, the material is thereby formed into a thin panel having, at is forward face where it meets and interfaces with the forming surface, the desired picture providing recessed front surface. Light passing from the rear through the translucent panel and transparent front wall, illuminates the lithophane-type picture. The translucent material occupying the container could be liquid, gas, powder, etc. as well as a formable solid material.
