Abstract: The present disclosure provides a semiconductor structure with having a source/drain feature with a central cavity, and a source/drain contact feature formed in central cavity of the source/drain region, wherein the source/drain contact feature is nearly wrapped around by the source/drain region. The source/drain contact feature may extend to a lower most of a plurality semiconductor layers.

Abstract: A semiconductor device includes: M*1st conductors in a first layer of metallization (M*1st layer) and being aligned correspondingly along different corresponding ones of alpha tracks and representing corresponding inputs of a cell region in the semiconductor device; and M*2nd conductors in a second layer of metallization (M*2nd layer) aligned correspondingly along beta tracks, and the M*2nd conductors including at least one power grid (PG) segment and one or more of an output pin or a routing segment; and each of first and second ones of the input pins having a length sufficient to accommodate at most two access points; each of the access points of the first and second input pins being aligned to a corresponding different one of first to fourth beta tracks; and the PG segment being aligned with one of the first to fourth beta tracks.

Abstract: Provided is a grease injection system including a plurality of grease injection devices and a host. The grease injection devices uses control information to output lubricating grease, and output a plurality of pieces of status information. The host receives the pieces of status information from the grease injection devices, and generates the control information based on the pieces of status information.

Abstract: A three-dimensional triangular paper block paper folding aid includes a primary forming board, which the top end being a base block, and the base block extends obliquely towards both sides to form two isosceles upper bevels, and then extends inwardly and obliquely to form two isosceles lower bevels, which being coupled into a right angle (90°). One of the sides of the primary forming board has a vertical midline with a length substantially equal to half of the length of the folding paper, and the turning points between the two upper bevel edges and two lower bevel edges on the other side of the primary forming board are connected into a horizontal midline with a width substantially equal to the width of the folding paper, and the vertical midline and the horizontal midline provide a positioning guide to the folding paper.

Abstract: A method of producing devulcanized and activated rubber particles from vulcanized rubber products includes providing a jet unit including a rotatable jetting head that has a plurality of self-rotating nozzles for producing an ultra-high-speed jet fluid, and impinging the vulcanized rubber products using the ultra-high-speed jet fluid. The ultra-high-speed jet fluid has a Reynold's number ranging from 100,000 to 4,000,000. The rotatable jetting head rotates at a rotating speed of not less than 2,000 rpm. Each of the self-rotating nozzles produces a jet fluid that has an initial apparent kinetic energy of not less than 10×103 KJ.

Abstract: A particulate rubber composition includes a plurality of rubber particles. At least some of the rubber particles have tensile fractured surfaces. The particulate rubber composition is produced by a method that includes disintegrating a cross-linked rubber product to form the rubber particles using a high-speed jets fluid to impinge the cross-linked rubber product. The high-speed jets fluid has a Reynold's number that ranges from 100,000 to 4,000,000. A product including a polymeric matrix material and the particulate rubber composition is also disclosed.

Abstract: An automatically rotatable lamp ball includes a power unit provided with a motor having its downward shaft driving two rollers to rotate and its upward shaft driving a lamp arm to rotate. The lamp arm is disposed thereon with a plurality of LEDs, and the integral body of the power unit and the lamp arm is received in the interior of a transparent outer casing and actuated to rotate therein for pushing the outer casing to roll freely at the same time. When the lamp arm is actuated to rotate, the LEDs installed thereon will simultaneously give out flickering lights in sequence and at intervals and, due to visual persistence, presenting freely movable stereoscopic light patterns or letters. So the invention is innovative and exclusively original in structure and having excellent entertaining effect.

Abstract: A toy having a motorized portion in the form of an inanimate object and a non-motorized portion in the form of an animate object. The two portions are tethered together, and the motorized portion is driven such that the non-motorized portion in the form of an animate object appears to be alive and in pursuit of the inanimate motorized portion. The motorized portion preferably is in the form of a substantially spherical hollow ball within which an eccentric driving mechanism is placed. The non-motorized portion is an animal with a furry body or bushy tail and is preferably a weasel, embodies by a furry tail having a face invisibly connected to the ball. The non-motorized portion is preferably tethered to the motorized portion with a substantially invisible attachment so that from a distance the two portions of the toy do not appear to be connected together.
