Title: Signal interval measuring device
Inventor: HARA YASOHACHI
IPC: G01R23/10
Filed: 2001-10-05
Abstract: PROBLEM TO BE SOLVED: To provide a signal interval measuring device which continues reliably measuring input signal intervals, in which a central processing unit may not become inoperative because of frequent interruptions even when overlapping of noises takes place in the input signal frequently. SOLUTION: When an edge detection circuit 11 detects a leading edge of an input signal 10, a capture register 13 is triggered to take in and store a value of a timer 12 at the time. The value is read by a central processing unit 16 to check a value change in the timer and calculate the signal interval. The central processing unit 16 does not receive a trigger signal from the edge detection circuit 11 but repeats operation of reading a value in the capture register independently and periodically. Thus, even when overlapping of noises causes a trigger frequently, a load for the process may not exceed a certain value and the central processing unit 16 may not become inoperable.

Title: Apparatus and method for measurement of deformation
Inventor: TANAKA KAZUNOBU
IPC: G01M17/007
Filed: 2001-10-12
Abstract: PROBLEM TO BE SOLVED: To find the deformation of a motion body. SOLUTION: A laser source 10 and a PSD 20 are attached to both ends in the object range of the motion body, and accelerometers 30-1 to 30-5 are attached to positions of both and to inspection parts to be set between both. When the difference in an acceleration between the accelerometer 30-1 and the accelerometer 30-5 is time-integrated, the relative displacement of both ends can be calculated. The relative displacement comprises a component due to the whole motion (rigid-body motion) of a vehicle and a component due to the deformation of the vehicle. Since the component due to the deformation can be found on the basis of the output of the PSD 20, it is subtracted from a displacement, and the component of the whole motion can be calculated.  Since the component of the whole motion in each inspection part is proportional to a distance up to each part from the origin, the component in each inspection part is decided when the component of the whole motion in both ends is found. Consequently, when the component of the whole motion is subtracted from the displacement in each inspection part to be found on the basis of the acceleration, the deformation in each inspection part can be evaluated.

IPC: F02D45/00
Filed: 2001-10-18
Abstract: PROBLEM TO BE SOLVED: To finely set a misfire ratio to the entire range of parameters indicating the operational state of an internal combustion engine with a small amount of data. SOLUTION: The misfire ratio corresponding to each range in which the engine speed and the throttle opening indicating the operational state of the internal combustion engine are divided by the predetermined unit is calculated (Step S103), and a determination value for the ignition/misfire changing according to the elapsed time for each cylinder (#1-#4 cylinder) of the internal combustion engine is calculated (Step S104 to Step S110). The determination value in the present operational state of the internal combustion engine is compared with the threshold based on the misfire ratio (Step S111), and the ignition/misfire to each cylinder of the internal combustion engine is controlled based on the result of the comparison (Step S112 and Step S113). Thus, ignition/misfire to the internal combustion engine is correctly controlled by setting a small amount of data.
