摘要:
A .pi./4 shift QPSK modulator includes a pre-processing part for subjecting an input transmitting code sequece to a pre-processing, a modulator part for selectively subjecting the transmitting code sequence received via the pre-processing part to a modulation in conformance with QPSK and a modulation in conformance with a .pi./4 shift QPSK, and an output part for outputting a modulated signal having a burst form based on an output of the modulator part depending on a burst signal having leading and trailing edges, where the pre-processing part carries out the pre-processing so that I-axis and Q-axis data supplied to the modulator part have the same symbol in succession at parts corresponding to the leading and trailing edges of the burst signal, so as to suppress generation of unwanted waves in the output part.

A desired shape of amorphous region is formed at a predetermined position in a metal crystal by introducing the desired shape of lattice defect at the predetermined position in the metal crystal, and then irradiating the lattice defect with an electron beam to form the desired shape of amorphous region at the predetermined position in the metal crystal.
摘要:
The present invention is a random accessible signal filing system containing magnetic discs, at least two buffer memories and a circuit for controlling the buffer memories in such a way that the write-in and read-out of at least two of the buffer memories may be alternately performed, whereby through random access, the required signals are selected and read out so as to be outputted as a series of signals.In this system, during the outputting of the signals, the signals coming from the magnetic discs are written into one of the buffer memories sector by sector at the read-out speed of the magnetic discs, and thereafter, are read out at the demodulating speed of the demodulator. The two buffer memories are so controlled that while the signals are written into one of them; the signals are read out from the other.

摘要:
A PDMS sheet that ensures good adhesion, handleability and stability to metal thin films or metal patterns of any desired shape, an optical element that is kept against de-bonding or exfoliation of metal patterns and has high reliability as well as good handleability and stability, and manufacturing methods thereof. The inventive optical element comprises a polydimethyl-siloxane sheet having a pattern-formation surface defined by one surface and a base surface defined by another surface, and a plurality of metal patterns positioned on the pattern-formation surface. Given a low-molecular-weight siloxane of a cyclic structure represented by [—Si(CH3)2O—]k where k is an integer of 3 to 20 inclusive, polydimethylsiloxane sheet comprises a structure where the content of the low-molecular-weight siloxane at the pattern-formation surface is more than that of the low-molecular-weight siloxane at the base surface, and a spacing between the adjacent metal patterns is variable by deformation of the polydimethylsiloxane sheet.
摘要:
A method for transmission of information about downlink and uplink parameters of a intermediate apparatus link in a multi-hop wireless communication system, the system comprising a first node apparatus, a second node apparatus and one or more intermediate apparatuses, each said apparatus being operable to transmit and receive information along a series of links forming a communication path for downlink and uplink communication, the communication path extending between the first node and second node apparatuses via the or each intermediate apparatus, each link comprising either a first node link between the first node apparatus and a said intermediate apparatus or an intermediate apparatus link between a said intermediate apparatus and a said apparatus which is not the first node apparatus, and the system having access to a minimum allocation unit for allocating time and transmission frequency bandwidth, the method comprising: obtaining values of downlink and uplink parameters for a particular intermediate apparatus link; mapping both values onto a single minimum allocation unit and transmitting them towards the first node apparatus.
