Abstract: An information display device is provided, which includes at least one processor, the at least one processor being configured to: acquire disaster information corresponding to a current position of a vehicle; generate a first image displaying the current position of the vehicle on a narrow-area map of vehicle surroundings; generate a second image displaying an entirety of a disaster-stricken area identified from the disaster information and the current position of the vehicle on a wide-area map of vehicle surroundings; and effect adjacent display of the first image and the second image at a display unit provided inside a vehicle cabin.

Abstract: Provided is an information processing device that includes at least one processor, wherein the at least one processor is configured to: acquire a satellite image of the ground, which is captured by an artificial satellite, for a target area based on disaster information; based on the satellite image, detect an obstruction on a road which relates to passage of a vehicle; and output a road for which no obstruction is detected as a traversable road.

Abstract: An exhaust gas sensor (100; 200) is configured so as to detect an oxygen concentration or air-fuel ratio in exhaust gas. The exhaust gas sensor includes a sensor element (10) and a manganese reaction layer (20). The sensor element detects an oxygen concentration or air-fuel ratio. The manganese reaction layer is formed on at least part of a surface of the sensor element and is formed of a substance containing an element capable of generating a complex oxide having manganese through reaction with a manganese oxide in the exhaust gas. The exhaust gas sensor is configured to detect an oxygen concentration or air-fuel ratio in exhaust gas of an internal combustion engine that utilizes a fuel having a Mn concentration in excess of 20 ppm.

Abstract: An exhaust gas sensor (100) is configured to detect an oxygen concentration or air-fuel ratio in exhaust gas of an internal combustion engine. The exhaust gas sensor includes a sensor element (10) and a glass coating film (20). The sensor element is configured to detect an oxygen concentration or air-fuel ratio in the exhaust gas sensor. The glass coating film (20) is formed on at least part of a surface of the sensor element and capable of absorbing a Mn component contained in the exhaust gas at 700° C. The internal combustion engine uses a fuel having a Mn concentration in excess of 20 ppm.
