Abstract:
An engineered epitaxial region compensates for short channel effects of a MOS device by providing a blocking layer to reduce or prevent dopant diffusion while at the same time reducing or eliminating the side effects of the blocking layer such as increased leakage current of a BJT device and/or decreased breakdown voltage of a rectifier. These side effects are reduced or eliminated by a non-conformal dopant-rich layer between the blocking layer and the substrate, which lessens the abruptness of the junction, thus lower the electric field at the junction region. Such a scheme is particularly advantageous for system on chip applications where it is desirable to manufacture MOS, BJT, and rectifier devices simultaneously with common process steps.

A device for calibrating a drill bill of a chuck includes an intermediate sleeve including two rear curved elements, a front shoulder, internal threads rearward of the shoulder, and an externally threaded extension projecting out of a front end; a front window including a diametrical calibrating line; an externally threaded rim secured to the internal threads to urge the window against the shoulder; and a ring having internal threads secured to the extension. A fastening of the chuck and the device, a loosening of the retainer ring, and a rotation of the rear holding member to rotate the drill bill can align the drill bill with the calibrating line.
Abstract:
A nucleating agent composition for increasing rigidity and toughness of polypropylene is provided. The nucleating agent composition comprises a carboxylate nucleating agent and a phosphate nucleating agent. The carboxylate nucleating agent is selected from the group consisting of sodium benzoate and hydroxyl aluminum para-tertiary butyl benzoate, and the phosphate nucleating agent is selected from any one of sodium 2,2′-methylene-di(4,6-di-t-butyl phenyl) phosphate and aluminum bis[2,2′-methylene-di(4,6-di-t-butylphenyl)] phosphate. The nucleating agent composition according to the present invention not only can significantly improve the bending modulus and thermal deformation temperature of polypropylene, but also can improve the impact strength of polypropylene.

Abstract:
A jointed bat includes a barrel, a handle, and a glue. The barrel is tubular and has one end fixedly connected to a top cap and the other end having a tapered first joint portion. An opening is formed at the end of the first joint portion. The handle is tubular and has one end fixedly connected to a knob and the other end having a tapered resilient second joint portion. At least a relief slit is formed at an end of the second joint portion. A dam protrudes from the second joint portion and abuts against an inner wall of the first joint portion. The second joint portion penetrates the opening to fit inside the first joint portion. The glue is filled between and fixedly connected between the first and second joint portions. Therefore, requirements for precision in production of the barrel and the handle are reduced.
