Patent MX-9804083-A (MX)
Title: Diversity device improved in ability to reproduce carrier in synchronous detection.
Inventor: IINUMA TOSHINORI
IPC: H04L27/227
Filed: 1998-05-22
Abstract: A diversity device is provided with detecting sections which output received phase data on each symbol by using a reference carrier reproduced from the signals received by means of a plurality of receiving systems, synthesizing sections which synthesize the I- and Q-components of the received phase data, and a judging section which demodulates digital symbol data from the synthesized I- and Q-components. The detection sections reproduce the reference carrier from the received signals by referring to the symbol data obtained from the synthesized I- and Q-components. Thus, a stable carrier can be reproduced, because the reference carrier is reproduced by using demodulated data obtained from diversity-synthesized received data.

Title: Concrete filled steel tubular pile-column integrated structure and construction method
Inventor: GUORUI GAO
IPC: E02D27/12
Filed: 2022-08-31
Abstract: Disclosed is a concrete filled steel tubular pile—column integrated structure and a construction method. A thread is welded to a steel tube of a concrete filled steel tubular pile, a lower end of the pile is made into a pointed, cone shape, corollary equipment applies an axial force and torque to a top of the pile at the same time, so as to screw the pile into a foundation, an outer sleeve connects the pile in a lower structure and a column in an upper structure through threaded connection at a pile—column connection position, and all parts for pile—column integrated construction are prefabricated in sections and mounted mechanically. Generally, the pile—column connection position is weak due to a large bending moment, and pile—column integral connection has important engineering significance, and avoids secondary pile—column connection, such that a construction period is shortened, and technical advantages are obvious.
