A symmetrical circuit layout structure includes a number of signal wires, a ground wire and a dielectric layer. The signal wires include a first portion placed on a first plane and a second portion placed on a second plane. The ground wire includes a first portion placed above the first portion of the signal wires and adjacent to the second portion of the signal wires, and a second portion placed below the second portion of the signal wires and adjacent to the first portion of the signal wires. The dielectric layer is placed between the first plane and the second plane.
Abstract:
A pallet assembly is composed of multiple pallet pieces and multiple wedging elements. Each pallet piece has four corners with four individual legs and multiples engaging holes defined on sides of the pallet piece. Each leg is rectangular in transversal cross-section and selectively has a mortise or a tenon to detachably and engages with other corresponding leg on an adjacent stacked pallet piece in the pallet assembly. Moreover, each wedging element is clamped between two adjacent juxtaposed pallet pieces to widen the pallet assembly. Thereby, the pallet assembly is versatile in changing sizes, easy to be assembled and disassembled, stable in use and convenient in storage.
Abstract:
A light emitting module includes a substrate, a driving circuit chip, a light emitting element and a connector. By providing the connector with conductive bumps and arranging it as a flip chip to contact the conductive bumps with bond pads of the driving circuit chip and the light emitting element, a light emitting module with a reduced bonding pitch but reliable performance can be produced. Alternatively, it can be the driving circuit chip instead of the connector functioning as a flip chip. The driving circuit chip includes conductive bumps in contact with bond pads of the light emitting element and the connector.

Abstract:
A method for rapidly identifying porcine estrogen receptor (ESR) marker comprises using published primers to amplify the target DNA fragment by polymerase chain reaction (PCR). The DNA fragment is cloned and then sequenced. The key positions of the sequence are modified to generate three primers which are used to amplify different DNA fragments with different genotypes by PCR to eliminate extra restriction cut reaction. A long one of the primers is to specifically amplify non-prolific allele, a short one of the primers is to specifically amplify prolific allele, and the remaining one is mutual and complimentary to the sequence. After PCR and electrophoresis, the sample with 90 bp band is identified as prolific genotype, the sample with 110 bp band is identified as non-prolific genotype, and the sample with 90 bp and 110 bp bands is identified as hetero-genotype.
Abstract:
A chip level EMI shielding structure and manufacture method thereof are provided. The chip level EMI shielding structure includes a semiconductor substrate, at least one ground conductor line, a ground layer, and a connection structure. The ground conductor line is disposed on a first surface of the semiconductor substrate, and the ground layer is disposed on a second surface of the semiconductor substrate. The connection structure is formed on a lateral wall of the semiconductor substrate for connecting the ground conductor lines with the ground layer to form a shielding. With such arrangement, the chip level EMI shielding structure can reduce the chip size and the manufacturing cost.
Abstract:
A tungsten-filament-like LED lamp structure includes a lamp shade, a heat dissipating frame, a lamp holder, a LED substrate, a LED light source and a light spreader assembly. The light spreader assembly includes a reflective device and a diverging element, wherein light rays transmitting through a light-permeable portion of the reflective device are diverged by the diverging element to generate frontward lighting, and reflective surfaces of the reflective device control the reflected light rays to generate sideward lighting and backward lighting and thus generate an optical field similar to that of a conventional tungsten filament lamp. Thus, the properties of energy saving, vibration resistant and long lifetime better than those of the conventional lamp can be achieved, and the invention can be directly applied to the conventional lamp structure to decrease the production and maintenance costs.
