Patent JP-2002285904-A (JP)
Title: Diagnostic apparatus for intake oxygen concentration sensor
Inventor: MATSUBARA TAKUJI
IPC: F02M25/08
Filed: 2001-03-23
Abstract: PROBLEM TO BE SOLVED: To readily and correctly determine failure of an intake oxygen concentration sensor. SOLUTION: A fuel injection amount of an engine at a time of evaporated fuel purging is corrected, based on the outputs from the intake oxygen concentration sensor 31 arranged to an intake passage of the internal combustion engine. In an electronic control unit(ECU) for controlling the engine, sensor outputs 31 under different two intake pressures are measured, a sensor output characteristics value is calculated from a changing amount of the intake pressures and a changing amount of the sensor outputs, and the failure of the sensor 31 is determined to exist, when the output characteristics value is not less than a predetermined upper limit value or not more than a prescribed lower limit value.  The upper limit is set based on the tolerance in the variations of the sensor outputs of respective products, and the lower limit is set in consideration of influence of lowering of actual intake oxygen concentration caused by the evaporated fuel purging or EGR. Therefore, the failure of the sensor is checked readily and correctly, so that failures of the sensor can be detected early.

IPC: A63F13/426
Filed: 2001-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a game device having reality. SOLUTION: This game system has a sword shape actually operating article 51. The location of the sword shape operating article 51 in an actual space is detected by a location detecting unit 6, and is converted into game space coordinates by a three-dimensional input converting means 13. When a player moves the sword shape operating article 51, the movement of a sword object in a game space is displayed in the same manner as the movement of the sword shape operating article 51. The movement of the sword object is stored as the location in the past in the game space. Whether the sword object has hit other objects in the game space or not is judged based on the stored locations. The player can play the game by moving himself rather than operating the objects in the game space, without feeling the sense of incongruity between the actual space and the game space.
