Bending-comb capacitor with a small parasitic inductance
2002 Symposium on VLSI Circuits. Digest of Technical Papers (Cat. No.02CH37302), 2003A new metal-metal capacitor with a small parasitic inductance, named a bending-comb capacitor (BCC), is proposed based on a standard digital CMOS technology. The BCC is applicable to high frequency circuits due to its high self-resonance frequency. An analytical evaluation of the capacitance from the geometry size is also presented.

Optimization of Pipe Induction Bending Process Parameters
ASME 2017 India Oil and Gas Pipeline Conference, 2017Hot pushed induction heating is a bending process used to bend pipes having a small bending radius with a large diameter. This is a complex process since it involves mechanical process of bending and thermal process of localized induction heating. This paper deals with the optimization of induction bending process parameters such as bending speed ...

International Journal of Pressure Vessels and Piping, 2015
Abstract This study focuses on the opening mode of induction bends; this mode represents the deformation outside a bend. Bending experiments on induction bends are shown and the manner of failure of these bends was investigated. Ruptures occur at the intrados of the bends, which undergo tensile stress, and accompany the local reduction of wall ...

Design Parameter Reliability Analysis of Induction Bends
Volume 6A: Pipeline and Riser Technology, 2014Induction pipe bends are essential multi-functional components in offshore applications performing not only as fluid conductors but also as structural members providing flexibility to the entire pipeline. The deforming mechanism of bends minimizes the effects of pipe walking, length changes due to thermal expansion/contraction, etc. However, the extent
