A snowboard binding mounting disk (24) includes a body (28) through which 3-hole and 4-hole patterns (8, 10) of mounting holes are formed. The centers of a pair of the 3-hole mounting holes are separated by a base distance (Z). The centers of a pair of the 4-hole mounting holes are separated by an end distance (Y). The end and base distances differ by a distance delta. The pair of end holes and the pair of base holes are positioned adjacent to one another so that the end and base holes overlap one another to create a pair of oblong, dual purpose holes (30). A removable and replaceable mounting element positioner (29) is mounted to the oblong holes at one of two stable positions. The position chosen is determined by whether the dual purpose holes are to be used for the 3-hole pattern or for the 4-hole pattern. The central opening (20) in the base is preferably made by stamping a grooved peripheral surface (22) sized to engage a complementary grooved surface (53) on the disk.

A test cell for use in a semiconductor manufacturing operation allowing alignment of semiconductor devices to be tested to a test station. The test cell is well suited for testing semiconductor devices on carrier strips. To aid in alignment, the test cell includes a down-ward looking camera and a simple upward looking sensor. Fiducials are acurately positioned relative to the test site, which are easily detected by the simple sensor. A controller within the test cell uses the output of the camera and the sensor, in conjunction with position sensors on a robotic assembly, to determine relative positions of the devices to be tested and the test station and issue the appropriate commands to align the devices to the test station.

A polymeric drift control concentrate is provided for admixture with an aqueous mixture designed for application to vegetation or soil by aerial or ground spraying or discharge. The concentrate reduces the likelihood that the water or aqueous mixture will drift away from its intended target, and suppresses the formation of dust on the ground.

A process for reducing the residual monomer level of a polymer latex prepared by emulsion polymerization comprises exposing the latex in a separate vessel from that in which the main polymerization has been carried out to conditions under which free radicals are produced by a secondary catalyst added to the latex, the said catalyst being oil soluble or having an oil soluble component. In a preferred embodiment a polymer latex prepared by the emulsion polymerization of styrene alone or a mixture containing styrene having a residual styrene level not exceeding 0.1% based on latex volume may be obtained.

A hat with interchangeable ornaments such as patches or badges. The hat has a surface that is viewable and has a magnetic attachment mechanism. The ornament has a complementary magnet that attaches. The rear of the ornament is flattened with extending magnets that extend into corresponding recesses in the hat. Surfaces are provided preventing twisting of the ornament relative to the hat once the ornament is attached to the hat. This can use, two cylindrical magnets.

Large diameter axial Super Low Noise flow fans and commercial air cooled apparatuses incorporating such fans are provided. The large diameter axial flow fan is mounted on the air cooled apparatus for generating an axial air flow in the air cooled apparatus for accomplishing the cooling. The fan has a diameter of at least four feet. The fan has plurality of blades. Each blade includes a leading edge opposite a trailing edge. The entire of the leading edge of each of the blades is linear and forward swept, and each blade includes a metallic outer surface.

A robotic die sorter having pick and place arm assemblies and a mutli-camera optical inspection system is disclosed. A pick arm of the pick arm assembly picks a die from a semiconductor wafer, and a place arm of the place arm assembly receives the die from the pick arm and places same in a reel of pocketed tape. After picking, the pick arm and the place arm are rotated into facing arrangement, whereupon the die is transferred to the place head of the place arm and a camera of the optical inspection system to detect defects in the die. After inspection, the place arm rotates toward the pocketed tape and places the die into the pocketed tape. Additional cameras of the optical inspection system allow for calibration of the pick and place arms, as well as monitoring of the die transfer process.

A snowboard (4) includes a core (10) having tip and tail portions (20, 22) with a center portion (9) therebetween. The tip and tail portions both include lightweight, high strength honeycomb material (18) to reduce the mass moment of inertia of the snowboard. Doing so reduces the spin weight of the snowboard and permits the user to turn the snowboard about a vertical axis (26) more easily.
摘要:
A method of compressing text by allocating word tokens to each unique word and phrase tokens to adjacent word tokens, to adjacent phrase tokens or adjacent phrase and word tokens, which occur in the text at least three times and changing the binary character code representation of the text so that the text is represented by phrase and word tokens. A data processing system for decompressing and displaying the compressed text.
