Title: Exhaust emission control device of internal combustion engine
Inventor: NISHIZAWA TORU
IPC: F01N13/02
Filed: 2002-09-25
Abstract: <P>PROBLEM TO BE SOLVED: To determine deterioration of exhaust purification catalyst.  <P>SOLUTION: At S101, a NOx sensor (concentration detection means) detects the concentration of NOx (exhaust component) in an exhaust passage at the downstream of NOx trap catalyst (exhaust purification catalyst). At S102, an activity transition time at which the NOx trap catalyst changes from an inactive state to an active state is detected based on the concentration of the NOx detected by the NOx sensor. At S103, whether the NOx trap catalyst deteriorates is determined based on the temperature T1 of the NOx trap catalyst at the activity transition time.  <P>COPYRIGHT: (C)2004,JPO

Title: Digital broadcast receiver and broadcast signal receiver
Inventor: HANAOKA TAKATSUGU
IPC: H04N5/44
Filed: 2002-09-26
Abstract: <P>PROBLEM TO BE SOLVED: To give beneficial information to the user of a digital broadcast receiver in an easily understandable mode.  <P>SOLUTION: When a broadcast receiver receives service information (SI), whether or not the version of the current SI is updated is judged on the basis of the first acquired service information in a step S61. When the version is updated, the difference A is calculated in the starting time of the currently broadcast program between the reference SI and the current SI in a step S62. When it is judged that the starting time is changed (the difference A is not 0) in a step S63, the difference A is preserved in a memory as a deviated time and the deviated time is displayed on a screen in a step S64. When it is judged that the starting time is not changed in the step S63, the difference B in the duration of the currently broadcast program between the reference SI and current SI is calculated in a step S65. When it is judged that the duration is changed (the difference B is not 0) in a step S66, the difference B is preserved in the memory as a deviated time in a step S67 and, at the same time, the deviated time is displayed on the screen.  <P>COPYRIGHT: (C)2004,JPO
