Designating A % as the area ratio, in an entire cross section of the solid electrolyte, of the whole cross section of regions having less than 3.3 mol % of Y2O3 relative to the total Zr and Y2O3, and designating B % as the area ratio, in the cross section of the solid electrolyte, of the entire cross section of regions (211) having at least 7 mol % of Y2O3 relative to the total Zr and Y2O3, the total area ratio (A+B), which is the sum of A and B, is 10% or more.

Abstract: The sensor element of an exhaust sensor has a solid electrolyte body provided with a detection electrode exposed to a gas to be detected, and provided with a reference electrode. A porous protective layer is provided on the outer surface of the solid electrolyte body including the surface of the detection electrode. The porous protective layer is composed of a plurality of aggregate particles bonded to each other. When a plurality of crystal grains constituting an aggregate particle are observed in cross section, the number of crystal grain boundary intersections where three or more of the crystal grains intersect, per unit area, is in the range of 1 to 10,000/?m2.

Abstract: A gas sensor includes a sensor element body having a porous layer provided on an outer surface, and a power supply device which supplies power to a heater element that is in the sensor element body. The amount of power being applied to the heater element by the power supply device when gas detection is being performed by the gas sensor in a steady state is designated as P [W], the volume of the length range of a heating region of the heater element provided in the sensor element body as V [mm3], and the applied power density as X [W/mm3], where X is a value expressed by P/V. In that case, the following relationship is satisfied between the applied power density X and the average thickness Y [?m] of the porous layer: Y?509.32?2884.89X+5014.

The processor is electrically connected to the memory, and is configured to acquire failure precursory data concerning the storage, compute a failure risk of the storage, based on the acquired failure precursory data, determine recommended values for two or more backup frequencies of data stored in the storage, a backup data amount, a permissibility of system load for backup, and a backup destination, based on the computed failure risk, and present a setting screen for a backup method in which the determined recommended values are set as initial values respectively for each setting item.

Abstract: According to one embodiment, an electronic apparatus sets a first password corresponding to a first input method and a second password corresponding to a second input method. The apparatus performs authentication processing for determining whether a password input by the first input method or the second input method is correct by comparing the password with a registered password. The apparatus determines which of the first input method and the second input method is used, and changes the registered password either to the first password or to the second password based on a result of the determination of the input method.

Abstract: According to one embodiment, an information processing apparatus includes a state change controller and a display processor. When a first key of a keyboard is pressed, the state change controller changes a state of a first operational environment. The display processor displays a first message indicative of a current state of the first operational environment in an informing area of a display screen for a first duration of time. When a second message indicative of a past state of the first operational environment is displayed by the display processor for the first duration of time in the informing area, the display processor display the first message in the informing area together with the second message.
