TL;DR: In this article, the clamp tabs are formed as an integral part of the die attach paddle, which prevents paddle movement and enhances the integrity of die bond and wire bonds, and they extend outward from lesser supported locations of the paddle to underlie a conventional lead clamp.
Abstract: A leadframe configuration for a semiconductor device has a die attach paddle with paddle support bars. In addition, clamp tabs extend outwardly from lesser supported locations of the paddle to underlie a conventional lead clamp. The clamp tabs are formed as an integral part of the paddle. Normal clamping during die attach and wire bonding operations prevents paddle movement and enhances integrity of the die bond and wire bonds.

TL;DR: In this article, a fixed structure for a compressor motor, which includes a cylindrical magnet paddle in which a plurality of magnet insertion holes are formed along a circumference thereof, and a magnet fixing ring or a varnish-type molding member for fixing the magnets, effectively fixes the magnets to the magnet paddle, for improving reliability and efficiency of the compressor motor.
Abstract: A magnet fixed structure for a compressor motor, which includes a cylindrical magnet paddle in which a plurality of magnet insertion holes are formed along a circumference thereof or a cylindrical magnet paddle alone, a plurality of magnets inserted into the magnet insertion holes of the magnet paddle or fixed to the magnet paddle, and a magnet fixing ring or a varnish-type molding member for fixing the magnets, effectively fixes the magnets to the magnet paddle, for thereby improving reliability and efficiency of the compressor motor as well as mass-productivity thereof.

TL;DR: In this article, a model based on wind-over-waves coupling (WOWC) theory is used to simulate a laboratory experiment and to explain the observed peculiarities of the surface stress distribution above a combined wave field: wind-generated-plus-monochromatic-paddle waves.
Abstract: A model based on wind-over-waves coupling (WOWC) theory is used to simulate a laboratory experiment and to explain the observed peculiarities of the surface stress distribution above a combined wave field: wind-generated-plus-monochromatic-paddle waves. Observations show the systematic and significant decrease in the stress as the paddle wave is introduced into the pure wind-wave field. As the paddle-wave steepness is further increased, the stress level returns to the stress level characteristic of the pure wind waves. Further increase in the paddle-wave steepness augments the stress further. The WOWC model explains this peculiarity of the stress distribution by the fact that the paddle waves significantly damp the wind waves in the spectral peak. The stress supported by these dominant waves rapidly falls when the paddle wave is introduced, and this decrease is not compensated by the stress induced by the paddle wave. With further increase in the steepness of the paddle wave, the stress supported by dominant wind waves stays at a low level while the stress supported by the paddle waves continues to grow proportional to the square of the steepness, finally exceeding the stress level characteristic of the pure wind-wave field.

TL;DR: In this paper, an improved device for collecting refuse by using a fixed holding member and moveable expander to releasably hold a bag open by virtue of tension forces exerted across the mouth of the bag.
Abstract: An improved device for collecting refuse by using a fixed holding member and moveable expander to releasably hold a bag open by virtue of tension forces exerted across the mouth of the bag. A paddle, spring-loaded to a closed position across the mouth, can also be hingedly rotated to an open position and held in the open position by a trigger. When an animal owner desires to have the paddle scoop refuse into the bag, he can manually move the trigger. This action releases the spring-biased paddle which then rotates under spring bias, scooping refuse before it, to the closed position. The scooped refuse, because of the propelling movement of the paddle's rotation, is thrown on into the bag. A moving mechanism, which is also spring-biased, can both cock the paddle in the open position and also release the bag. As the moving mechanism pulls the paddle toward the open position, a latch pin connected through a cable to the paddle is caught and held by the trigger. The moving mechanism can then return to its normal resting position under the action of spring bias, while the paddle remains in the caught, cocked position. When it is desired to release the paddle, the trigger is manually depressed and the paddle returns under spring-bias to its normally closed position.

TL;DR: In this paper, a paddle boat with folding steering and folding steering is described, where a paddle is adapted to remain in a substantially vertical orientation during movement of the boat during the boat's motion.
Abstract: A paddle boat comprising a plurality of floats, collapsible driving and propelling apparatus, folding steering apparatus, the driving and propelling apparatus and steering apparatus adapted for mounting onto the floats during use of the paddle boat, particularly wherein the driving and propelling apparatus includes a paddle adapted to remain in a substantially vertical orientation during movement of the boat. Preferably, the driving and propelling apparatus comprises a stationary base element foldably mounted onto the main frame and defining a first rotation axis, a crank shaft defining at least one arm and an axle portion rotatably mounted onto the stationary base for rotation about the first rotation axis, a stationary extension element foldably mounted onto the base element and defining a second rotation axis parallel to and spaced from the first rotation axis, a paddle mounted upon each of the arms, at least one rod rotatably mounted onto the extension element and arranged for rotation about the second rotation axis through a restricted arc, and a member slideable relative to each rod and fixedly mounted onto each of the arms, whereby rotation of the arms about the first rotation axis causes the member to move slideably with relation to the rod and cause its rotation about the second rotation axis, the paddle being adapted for movement along the length of the rod as it rotates through the restricted arc such that the paddle remains in a substantially vertical orientation throughout its movement.
