摘要： A melt spinning apparatus includes an apparatus body, a nozzle configured to extrude melted resin in the apparatus body, and a barrel having an air discharge passage arranged around this nozzle to discharge hot air. The discharge passage includes a sloped passage and a parallel passage that extends along the nozzle. At an intersection of imaginary lines extending along the centerlines of the sloped passage, an imaginary merging section is defined. An open end of the nozzle is positioned on the downstream side of the imaginary merging section of the hot air blown diagonally forward toward a periphery of the nozzle. To manufacture a sheet of a nonwoven fabric, the melted resin is discharged from the nozzle and then the hot air swirling diagonally forward is blown toward the periphery of the nozzle. This causes the melted resin to be formed into spiral fibers. Those fibers are blown onto the belt of a conveyor belt apparatus to manufacture a nonwoven fabric sheet.

摘要： A melt spinning apparatus includes an apparatus body and a nozzle for extruding melted resin, a primary hot air passage formed around the nozzle, and a secondary hot air passage formed in a zone outside of the primary hot air passage, which are formed in the apparatus body. The primary hot air passage discharges primary hot air onto fibers of the melted resin extruded from the nozzle. The secondary hot air passage discharges secondary hot air to maintain the temperature of the primary hot air. The discharge angle of the secondary hot air from the secondary hot air passage is set in a range of 0° to 50° with respect to the direction of the melted resin extruded from the nozzle. The secondary hot air forms an air curtain that blocks the atmospheric air.

摘要： A semiconductor device includes a semiconductor chip formed with connection terminals, an elastic structure interposed between a main surface of the chip and a wiring substrate formed with wirings connected at first ends thereof to the connection terminals, and bump electrodes connected to the other ends of the wirings. The connection terminals may be at a center part or in peripheral part(s) of the chip main surface and both the elastic structure and wiring substrate are not provided at locations of connection terminals. A resin body seals at least the connection terminals and the exposed first ends of wirings (leads). In a scheme in which the connection terminals are located in a peripheral part of the chip main surface, the wiring substrate protrudes beyond the chip boundary where the connection terminals are arranged, and the resin body shape is restricted by the protruding part of the wiring substrate.

摘要： An insert is held in a cavity within a die set by a movable hold member. Molten resin is injected into the cavity when the insert is held by the hold member. The hold member is separated from the insert at a given timing. A surface of the hold member is heated to a temperature higher than a temperature of an inner surface of the die set. The hold-member surface contacts the molten resin. The die-set inner surface is exposed in the cavity.
