摘要:
A method of manufacturing a reuse paste includes the steps of preparing a fiber piece housing paste, fabricating a filtered recovery paste and fabricating a reuse paste. At the step of preparing a fiber piece housing paste, there is prepared a fiber piece housing paste including a conductive paste having conductive powder and a resin, and a fiber piece taken away from a prepreg to be used for manufacturing a circuit board. At the step of fabricating a filtered recovery paste, the fiber piece housing paste in a paste state is filtered as it is by using a filter and a filtered recovery paste is thus fabricated. At the step of fabricating a reuse paste, at least one of a solvent, a resin and a paste having a different composition from the filtered recovery paste is added to the filtered recovery paste, and the reuse paste is thus fabricated.

摘要:
The present invention provides a waveform data compression apparatus which can express waveform data by a small amount of compression data obtained by compressing the aforesaid waveform data, and a waveform data expansion apparatus which can reproduce the compression data produced by the aforesaid waveform data compression apparatus to obtain the original waveform data. The. waveform data compression apparatus interpolates waveform data of addresses before and behind the waveform data of an objective address in a block to be processed to acquire interpolated data of the objective address to be processed, and uses difference data between the interpolated data and the waveform data of the objective address to be processed, thereby compressing the waveform data. The waveform data expansion apparatus operates to perform reverse process to that performed by the waveform data compression apparatus.
