    摘要： A semiconductor integrated circuit which includes a central processing unit, one or more peripheral circuits, one or more external terminals for transferring signals to or from the integrated circuit, and circuits for selecting the central processing unit or one of the peripheral circuits and solely operating the selected one in a test mode. The circuit for selecting includes a test mode control circuit and a signal control circuit. The test mode control circuit generates and supplies control signals in response to test operating signals having particular timings different from those of an actual operating signal inputted through the external terminal in a normal mode. The signal control circuit serves to separate the selected one from the others in a manner to allow the separated one to solely operate in the test mode.

    摘要： A gas sensor element is disclosed which includes a solid electrolyte body, a measurement electrode, a reference electrode, a porous diffusion-resistant layer, a catalyst layer, and a plurality of protective layers. The catalyst layer is provided on an outer surface of the porous diffusion-resistant layer through which a measurement gas is introduced to the measurement electrode. The catalyst layer is comprised of a noble metal catalyst and catalyst-supporting particles. The protective layers are provided in layers on the catalyst layer and comprised of oxide particles. The average particle diameter of the catalyst-supporting particles of the catalyst layer is less than or equal to the average particle diameter of the oxide particles of the one of the protective layers which adjoins the catalyst layer. The further the protective layers are from the catalyst layer, the larger the average particle diameters of the oxide particles of the protective layers are.
