Abstract: This invention discloses a fluoroplastic lining manufacture and application technology, and more particularly to a fluoroplastic composite product and its manufacturing method. The product is composed of fiberglass, perfluorinated ethylene-propylene (FEP) and polytetrafluoroethylene (PTFE), wound sequentially on a stainless steel support mold, and then an alkali-free fiberglass strip is wound around an external surface. The product is pressed and sintered at a high-temperature melting condition to permeate the perfluorinated ethylene-propylene (FEP) into gaps on a surface of the fiberglass, and the semi-finished product is taken out from a furnace, and the alkali-free fiberglass strip is removed, and a finished good is formed or cut into plates after demolding. The invention breaks through the technical bottleneck of producing a polytetrafluoroethylene (PTFE) lining for large equipments, reducing the consumption of a large quantity of electric power and coal as well as lowering the transportation cost.

Abstract: A piezoelectric motor has an actuator which drives a slider. The actuator has a rectangular steel core of square cross-section with an axially projection driving tip. A ceramic piezoelectric element is bonded to each of the four faces of the core. Each piezoelectric element has four quadrants covered by quadrant electrodes on one side and a common or earth electrode on the other side contacting the core which electrically joins the common electrodes. By selective excitation of corresponding diagonally opposite quadrants of opposite piezoelectric elements, the actuator is made to drive the tip in either the X direction or the Y direction. The preferred slider is a spherical ball held captive within arms extending from a housing of the actuator. The driving tip is pressed against the ball by a preload spring acting on the actuator.

Abstract: An audio encoder includes a time-frequency mapping block, a psychoacoustic model block, a middle/side (M/S) encoding block, a parameter calculation block, a bit allocation and quantization block and a bitstream formatting block. The encoder is forced to operate in M/S mode for reducing the calculation time of the parameter used for bit allocation, quantization and encoding. In addition, the calculation of the parameter only needs to consider the middle and side channels but not the left and right channels, thus the complexity of the psychoacoustic model for analyzing the input audio signal can be reduced.
