Title: Exhaust emission control device for internal combustion engine
Inventor: YOSHIMURA SEIJI
IPC: F02D41/14
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To ensure high NOX absorption capacity of an NOX absorbent by rich spike, and to block discharge of a large quantity of unburnt HC and CO from the NOX absorbent during rich spike. SOLUTION: When an air-fuel ratio of inflow exhaust gas is lean, an NOX is absorbed, and when an air-fuel ratio of inflow exhaust air is rich, absorbed NOX is discharged and reducing NOX absorbent 19 is arranged in an engine exhaust passage. By repeatedly effecting rich spike at which an air-fuel ratio of inflow exhaust gas to the NOX absorbent 19 is temporarily switched, NOX absorbed from the absorbent 19 is discharged and reduced. An air-fuel ratio sensor 43 is arranged in an engine exhaust passage situated downstream for the NOX absorbent 19. After rich spike is started, a rich spike time is updated based on an output signal from the air-fuel ratio sensor 43 so that after rich spike is started, a rich signal is not outputted from the air-fuel ratio sensor 43.

Title: Braking device for vehicle
Inventor: NAKAZATO AKIHIRO
IPC: H02P3/16
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To stop a vehicle completely by operating a motor-driven braking device when vehicle speed is above a prescribed speed, and operating a friction braking device, when the vehicle speed is below the prescribed speed. SOLUTION: A control circuit 7 loads a wheel rotational speed signal Vw and a brake pedal effort signal F, and discriminates whether or not a brake pedal 9 is depressed. With this discrimination, when it is determined that the brake pedal 9 has been depressed, it is discriminated whether or not the wheel rotational speed signal Vw is lower than a prescribed speed. If the wheel rotational speed signal Vw is higher than the prescribed speed, braking is performed by a motor 1. If the wheel rotational speed signal Vw is lower than the prescribed speed, braking is performed with a friction brake 2. As a result, it is thus possible to positively stop a vehicle.

Title: Power interruption detecting
Inventor: AOTO HISASHI
IPC: H02H3/24
Filed: 1987-11-30
Abstract: PURPOSE:To inform whether previous power interruption of a data processor is due to interruption of an AC power source upon throw-in of the power source, by holding a power interruption information in a register through processing of a central processing unit and erasing the information upon elapse of source holding time of a power source circuit. CONSTITUTION:A power interruption detecting circuit 2 detects power interruption and a central processing unit 3 holds a power interruption information in a register 4. Since power is recovered upon elapse of source holding time of a power source circuit for instantaneous power interruption, CPU3 can erase the power interruption detection information held in the register 4. Upon occurrence of long time power interruption, the power interruption detection information is held stored continuously in the register 4. When AC power source is thrown in again, CPU3 reads out content of the register 4 and performs informing process.
