An object of the invention is to provide an injection molding process for preparing thermoplastic resin molded articles and an injection molding apparatus for use in practicing this process, the process and the apparatus being adapted to supply a blowing agent, especially a nonreactive gas such as carbon dioxide or nitrogen gas, to a thermoplastic resin continuously at a relatively low pressure with good stability to incorporate the agent or gas into the resin. As shown in FIG. 3, a resin in a cylinder (2) of an injection molding machine (1) as melted by rotating a screw (3) is mixed and dissolves carbon dioxide which is supplied to the molten resin from a gas supply opening (5) formed in the screw (3). An amount of the gas-incorporating molten resin is measured out and injected into a mold cavity to obtain an expansion-molded article. To incorporate carbon dioxide into the molten resin, the gas is supplied from a gas inlet (11) formed in a rear end portion of the screw to a portion (4a) not fed with the resin and positioned between front and rear screw flights and closer to the front flight, through a gas supply channel 6 extending through the screw and via the supply opening (5).

A personal respiratory protection device 10 that comprises a mask body 12 that has a structure 35 located on it for receiving a clean air supply source such as a filter cartridge 14. The clean air receiving structure 35 has a first threaded portion 34. The clean air supply source has a second threaded portion 58 that has a thread 60 that mates with a thread 36 of the first threaded portion 34. The first and second threaded portions 34 and 58 engage each other at a high thread pitch and include an integral détente. A stop prevents over-rotation of the clean air supply source 14 relative to the mask body 12 during the securement operation. The inventive device allows the clean air supply source 14 to be attached to the mask body 12 with minimal rotation and is sufficiently intuitive that users may only need one hand to attach and replace the clean air source component 14 without having to remove the respirator 10 from their face.

Instruments and methods for measuring a property of a shape memory alloy are provided. The instrument includes a base plate, a non-contact movable mass, a force gauge, an actuator, a biasing spring, a heater for heating the shape memory alloy, and a non-contact displacement detector. The biasing spring and the shape memory alloy are disposed whereby a force applied thereby is applied substantially through a center of stiffness of the movable mass. The displacement detector measures a displacement of the movable mass in a colinear direction with a direction of movement of the movable mass and with a direction of the force applied by the biasing spring and the shape memory alloy. The linear motion stage comprises a housing and at least one guide bar, and wherein a calculated axial expansion of the guide bar is substantially equal to a calculated axial expansion of the base plate.

Flow velocity sensor and a length sensor are provided on or near an edge of the lip plate which the air jet from the embouchure hole impinges against. Jet flow velocity Ue at the edge and a jet-blowout-outlet-to-edge distance d are detected by the sensors. Jet transfer time τe is calculated by an equation of τe=d/Ue, and a jet traveling angle θe′ is calculated by an equation of θe′=2πfso1×τe (where fso1 represents a frequency of a tone to be generated). When θe′ has decreased to π/2 during tone generation in a primary mode, the mode changes to a secondary mode to raise the pitch of the currently generated tone by one octave. When θe′ has increased to 3π/4 during tone generation in the secondary mode, the mode changes to the primary mode to lower the pitch of the currently generated tone by one octave.

A towed personal watercraft apparatus includes a submergible unit and a platform. The submergible unit comprises at least two independent vertical stabilizers and one or more hydrofoil units mounted to at least one of the vertical stabilizers. One or more of the hydrofoil units is pivotally attached to the vertical stabilizers. Pivotal attachment can include a torsion spring or roller bearing to allow the hydrofoil units to pivot or rotate about the pitch axis of the platform, thereby improving stability of the towed personal watercraft. Rotation of the hydrofoil units can be limited for functional concerns and performance. For example, rotation of the hydrofoils about the pivot can be allowed in a first direction to prevent a nose dive, while being restricted in a second direction to facilitate a launch of the watercraft out of the water. The platform includes a user mount, such as foot holds or equivalents.

A magnetic recording head for use in perpendicular magnetic recording having a design that allows the write coil to be manufactured by a damascene process for increased coil pitch and reduced coil resistance. The magnetic write head includes a photoresist dam structure that allows a hard baked photoresist to be formed that does not extend to the air bearing surface (ABS). Since the photoresist dam prevents the hard baked photoresist from reaching the ABS, the damascene process, in which the hard baked photoresist remains in the finished write head, can be used to produce the write head. The use of such a damascene process advantageously allows the space between the coil turns to be reduced, which maximizes the number of turns that can be used and also maximizes the number width to which the coil turns can be constructed, thereby minimizing the electrical resistance of the write coil.

A process is disclosed for creating semiconductor devices such as RFID assemblies wherein an array of dies is spaced apart at a pitch matching the pitch of straps on a web of straps before they are mounted to a chip carrier substrate. The substrate is then cut into strips to form one or more linear aggregations of dies. The linear aggregation of dies is then transferred by an assembly mechanism onto the web of straps and electrically attached to a plurality of straps or interposers arranged in a corresponding array. The spacing, or pitch, between the dies in the die array may be changed to match the pitch of the straps or interposers in the corresponding array before or after a wafer substrate is removed from the die array. An RFID device created using the process inventive is also disclosed.
