Title: Slip controller for automobile
Inventor: NAGAOKA MITSURU
IPC: B60W10/188
Filed: 1987-07-10
Abstract: PURPOSE:To keep off any large yawing in a car body as securing each driving force of driving wheels by detecting the yawing of the car body, and when this yawing is larger, making the desired value of slip control smaller than at time of small. CONSTITUTION:A slip controlling device D controls a torque regulating device C when a alip detecting device A detects a slip state of driving wheels B against a road surface, and it performs its slip control so as to cause each slip of these driving wheels B to become the specified desired value finally. This desired value is changed and set by a desired value altering device E so as to make the desired value smaller when yawing is larger than at time of small, according to size of the yawing to be detected by a yawing detecting device F. Thus any large yawing in a car body can be prevented from occurring as securing each driving force of driving wheels B so effectively.

Abstract: PURPOSE:To eliminate the erroneous alarm based on thermal expansion at the start time of a nuclear reactor apparatus, by performing the pattern analysis of an abnormal sound signal. CONSTITUTION:With respect to the vibration sound sensed by accelerometers 1-10, usual background noise is compared with loose part vibration sound and, when the comparing result is a definite ratio or more, an alarm is generated from a loose part detector and, on the basis of said alarm, the abnormal sound sensing part of an FER 21 senses that abnormal sound is generated. On the basis of the number of alarm within a unit time, the true or error of the abnormal sound is judged by a right/error judge part 23. A signal clearing this is further inputted to a pattern analytical part 24 and the pattern of the combination of the sensors detecting the abnormal sound stored in a memory and the timewise shift thereof is compared with a detection signal. Further, frequency analysis and energy analysis are performed. By this method, the erroneous alarm based on thermal expansion at the start time of a nuclear reactor can be judged and the wasteful work of an operator or machinery due to said erroneous alarm can be prevented.
