Abstract: A semiconductor integrated circuit having a test circuit built therein is disclosed which consists of an A/D converter to be connected to a peripheral circuit, a digital circuit connected to the A/D converter, a digital signal switching device for selectively connecting to the output of the A/D converter and that of the digital circuit, and a boundary scan output circuit connected to the output of the digital signal switching device, wherein the digital signal switching device connects the A/D converter to the boundary scan output circuit in a normal mode, while the signal fetched in the boundary scan output circuit is outputted therefrom in test mode. Semiconductor integrated circuits having an analog circuit built therein and an analog integrated circuit in which a test circuit is built-in are also disclosed.

Abstract: A double-scanning non-interlaced television receiver performs scanning line interpolation by using a memory to reproduce a 1/60 second frame with 525 scanning lines. The receiver has a picture-in-picture (P-in-P) function which inserts a frame (sub-picture) into a part of another frame (main picture). The receiver is provided with a signal processing circuit for implementing the scanning line interpolation and a memory having a frame-wide capacity for producing a sub-picture. The receiver (1) produces a video signal for the main scanning line and a video signal for the interpolated scanning line for the main picture and a video signal for the main scanning line and a video signal for the interpellated scanning line for the sub-picture and (2) performs a double-scanning conversion, thereby providing a sub-picture without causing line flicker.

Abstract: The adsorbent for separation and recovery of CO is prepared by contacting an alumina or silica-alumina carrier with a mixed solution or dispersion of a cupric salt and a reducing agent in a solvent and, then, removing the solvent. The preferred cupric salt is cupric chloride.

Abstract: N-formyl-.alpha.-L-aspartyl-L-phenylalanine methyl ester is obtained by reacting L-phenylalanine methyl ester with N-formyl-L-aspartic acid anhydride in a reaction solvent containing acetic acid or acetic acid and formic acid in a complete mixing type continuous reaction mode.

Abstract: A process for producing N-formyl-aspartylphenylalanine or its methyl ester, wherein aspartic acid is reacted with formic acid and acetic anhydride in approximately stoichiometric quantities in the presence or absence of a catalyst and phenylalanine or its methyl ester is directly added to the dehydration mixture. This process has a higher yield of the desired N-formyl-dipeptide and minimizes the amount of by-products and unreacted starting materials.

Abstract: An adsorbent for separation - recovery of CO comprising a composite carrier (X) composed of a carrier (a) formed of silica and/or alumina and an active carbonized material layer (b) formed thereon, on which a copper compound (Y) is carried.By applying the method of the pressure swing adsorption and/or temperature swing adsorption, using this adsorbent, high purity CO may be separated and recovered on industrial scale from converter gas and other gases containing CO.

Abstract: An ink composition for waterless lithography having good printing properties which makes it possible to print from a lithographic printing plate with one fluid without using any kind of water fountain system to mask a non-image area, said ink composition containing high-boiling petroleum solvent mixtures which have a boiling point higher than 200.degree. C. and which contain less than 5% by volume of aromatic components, and in addition to the above containing an aliphatic acid ester, an aliphatic dibasic acid ester and/or a phosphoric acid ester.
