Abstract: An electrical connector includes an insulative housing and a plurality of contacts retained within the housing as a contact module. The housing includes a base and a mating tongue forwardly extending from the base. The contacts are arranged with two rows contacting sections respectively exposed upon two opposite surfaces of the mating tongue, and one row mounting sections for mounting to a same plane of a printed circuit board. Each contact has a linking section between the contacting section and the mounting section. The contacts are grouped by one grounding contact associated with a pair of neighboring differential pair signal contacts in an isosceles triangular configuration wherein the grounding contact is located at the top apex. The linking section of grounding contact of the outermost group is widened compared with those of the remaining contacts for lowering the corresponding impedance.

Abstract: The present disclosure provides a kitchen appliance with a drawer. The kitchen appliance has a body, a drawer and a position-limiting lock assembly.

Abstract: A method of manufacturing an epitaxiable heat-dissipating substrate comprises the steps of (A) forming a roughened surface on a substrate made of a polycrystalline or amorphous material with a high thermal conductivity coefficient; (B) forming a flat layer on the roughened surface; and (C) forming a buffer layer on the flat layer. The flat layer reduces the surface roughness of the substrate, and then the buffer layer functions as a base for epitaxial growth, thereby being directly applicable to production of semiconductor devices which are flat and capable of isotropic epitaxial growth.
