Abstract: A display apparatus includes a display unit configured to display an image, a wireless tag, a wireless communication unit configured to wirelessly communicate with an external terminal apparatus, and a control unit configured to switch an operation state of the display apparatus to at least a normal operation state and a power saving state. When detecting that the wireless tag communicates with the terminal apparatus in the power saving state, the control unit shifts the operation state to the normal operation state. The wireless communication unit returns from the power saving state to the normal operation state and establishes a wireless communication with the terminal apparatus.

Abstract: A vehicle includes a vehicle body having a front wheel housing, an axle, a disk wheel fixed to the axle in the front wheel housing and a tire mounted on the disk wheel. The vehicle further includes a breaking member that is provided projecting from the vehicle body toward the disk wheel. The breaking member breaks the disk wheel when the vehicle body is crashed at a front thereof at a predetermined speed or higher.

Abstract: A method of manufacturing a perovskite catalyst composed of perovskite oxide includes mixing step, firing step and acid-treating step. In the mixing step, an A-site material and a B-site material are mixed at a stoichiometric ratio such that the A-site is increased, compared to that of a theoretical composition ABO3 of perovskite oxide in which a ratio of A-site and B-site is 1:1. In the firing step, the obtained mixed powder is fired. In the acid-treating step, the obtained fired powder is acid-treated with acid of pH 2 or more and less than pH 7.

Abstract: 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.

Abstract: A data bus control circuit is formed on a single semiconductor integrated circuit that includes input/output terminals for external data exchange and a plurality of functional blocks including a CPU. A bi-directional bus buffer buffers data sent over a data bus between the CPU and the input/output terminals. The signal propagation direction of the bus buffer is determined according to a logic level of a read control signal supplied from the CPU.

Abstract: 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.
