Title: Method and apparatus for detecting acoustic reflection
Inventor: RICHIYAADO PII ANDORESEN
IPC: G01N29/11
Filed: 1988-12-14
Abstract: PURPOSE: To discriminate between ice and air present on a detection surface accurately by transmitting an acoustic interrogation pulse to a detection surface along an acoustic transmission medium and detecting acoustic energy reflected by the detection surface. CONSTITUTION: A piezoelectric converter 38 is excited with a drive pulse ending at time T=0. A first reflection pulse from a reference surface 30 is detected at time T=Tr and then a reflection pulse from a detection surface 26 is detected at time T=Ts. At time T=Tr, the amplitude of the reference pulse is partially a function of acoustic impedance at the reference surface 30 and it is substantially constant. At time T=Ts, amplitude of pulse from the detection surface 26 is a function of acoustic impedance at the detection surface 26. That pulse has a first high amplitude and a second low amplitude on the interface with ice.  When a reflection coefficient is determined, amplitude of reflection detection pulse is divided by the amplitude of reflection reference pulse and normalized and then a discrimination is made between ice and air present on a detection surface 26 based on the value thus obtained.

Abstract: PURPOSE:To obtain a single crystal silicon thin film of low resistance value containing high concentration impurity, by transforming an amorphous layer into single crystal, activating impurities, and heating an element at a temperature capable of eliminating fine defects in the single-crystallized layer. CONSTITUTION:After a single crystal Si thin film 2 and an insulating film 7 are formed on an insulating substrate 1, a mask 3 is partly formed, and phoshorus is implanted. After the implanted region of the thin film 2 is completely turned into the amorphous state, and an amorphous layer 4 containing phoshorus is formed, Si is implanted in the interface between the layer 4 and the substrate 1. After the mask 3 is eliminated, annealing is performed in nitrogen. Thus solid phase growth is generated in the lateral direction from the region 2 where ions have not yet been implanted, the layer is almost single- crystallized, and the greater part of phosphorus is activated. After that, annealing is performed in nitrogen at a high temperature, thereby eliminating residual fine defects and completely activating phosphorus. Hence a single crystal Si thin film 6 containing phosphorus is formed.
