The present invention relates to a method for covering a substrate with a cylindrically shaped heat-shrinkable film, particularly to a method for covering a cylindrically shaped heat-shrinkable film so as to fit the contour of a substrate by conducting the heat treatment in multiple steps at different temperatures.
摘要:
A transmission method of simultaneously transmitting a first modulated signal and a second modulated signal at a common frequency performs precoding on both signals using a fixed precoding matrix and regularly changes the phase of at least one of the signals. One of signal generation processing in which phase change is performed and signal generation processing in which phase change is not performed is selectable, thereby improving general versatility in signal generation.

Disclosed is a relay method including: receiving, as input, respective reception signals by two receive antennas, the reception signals each including a reception signal resulting from multiplexing respective transmission signals transmitted by two transmission antennas in a first frequency band; performing frequency conversion on the reception signal received by one of the receive antennas so as to obtain a signal of a third frequency band; and performing frequency multiplexing on the signal having the third frequency band and the reception signal received by the other of the receive antennas.
摘要:
A transmission method for transmitting a first modulated signal and a second modulated signal in the same frequency at the same time. Each signal has been modulated according to a different modulation scheme. The transmission method applies precoding on both signals using a fixed precoding matrix, applies different power change to each signal, and regularly changes the phase of at least one of the signals, thereby improving received data signal quality for a reception device.
摘要:
All data symbols used in data transmission of a modulated signal are precoded by hopping between precoding matrices so that the precoding matrix used to precode each data symbol and the precoding matrices used to precode data symbols that are adjacent to the data symbol in the frequency domain and the time domain all differ. A modulated signal with such data symbols arranged therein is transmitted.
摘要:
It is intended to provide an electronic component mounting device and an operation performing method for mounting electronic components so that both the operation quality and the productivity can be improved. In operation performing procedures, when an electronic component belongs to the first division, an operating head is made to move up and down based on an approximate operation position height derived from an approximate curved surface of the top surface of a board which is calculated by using the height measurement result obtained by measuring a plurality of height measuring points on the surface of the board, and when the electronic component belongs to the second division, the operating head is made to move up and down based on an individual operation position height obtained by individually measuring the board height at the operation position.
