摘要:
A manufacturing method for polycarbonate comprising �I! a process for manufacturing diaryl carbonate from an aromatic hydroxy compound and an aromatic hydroxy compound, �II! a process for manufacturing polycarbonate by solution polymerization of the diaryl carbonate obtained in �II! and an aromatic dihydroxy compound in the presence of a catalyst comprising a nitrogen-containing basic compound, and �III! a process for separating and removing the nitrogen-containing compound from the aromatic hydroxy by-products in �II! and returning the resultant aromatic hydroxy compounds to process �I! effectively reuses aromatic hydroxy by-products (e.g., phenols) of polycarbonate manufacturing to manufacture diaryl carbonate, while suppressing the production of alkyl aromatic ethers and then uses this diaryl carbonate to manufacture polycarbonate with good productivity.
摘要:
A plurality of content-addressable-memory sub-arrays simultaneously performs a parallel comparison between data sequences arranged in a row direction of memory cells and a search data sequence input from outside, and outputs a result of the comparison for each data sequence. A first input pin receives an input of the search data sequence. A second input pin receives an input of a search data sequence arbitrarily designating a content-addressable-memory sub-array. Each of the content-addressable-memory sub-arrays includes an activation control unit that controls activation of the content-addressable-memory sub-arrays based on the search data sequence.

摘要:
Two frame buffer memories are used. Depth coordinates are stored in a data bank memory of the first frame buffer memory. A comparing unit makes comparison between the depth coordinate of an image data currently displayed and the newly input depth coordinate, and thereby outputs a comparison result signal from a comparison result signal output terminal. In the second frame buffer memory, color data is stored in a data bank memory, and the comparison result signal sent from the first frame buffer memory is input via a comparison result signal input terminal. An image processing unit performs blending processing on the color data in response to the comparison result signal, and rewrites the color data.
