Those racks are limited in length owing to the influence of accumulative pitch errors. Then, the rotating number required to the pinion accuracy, is to be carried out by the repeated rolls of several times. On the gear rolling, it is the most defective point that the respective faces of involute teeth worked by the moment of generating motion are depressed at the pitch points. From the investigation of those finished rolling conditions, it is revealed that the accuracy of rolled teeth is controlled by the rolling times and directions, and that two-way rollings maked up by the combination of a normal and a reverse roll are the most effective way in this system. Then the collapses found near the pitch circle of the first rolled teeth are greatly decreased. And, the tooth profile error, pitch error and runout of the hobbed pinion are improved clearly.

The subjects were 27 healthy male students. We decided to report the significant level by examining correlations from the statistical point of view. The results obtained were as follows; 1) The results of experiment showed that blood pressure was classified, "rising" type and "falling" type. 2) Blood pressure and pluse pressure increased together. 3) Although respiration rate made no difference the respiration curve changed. 4) The amplification of EEG (electroencephalogram) amplitudes was observed under the noisy condition.

This paper presents a method to estimate the parameter values with accuracy for nonlinear system. The basic principle of the method is the algorithm that is based on weighted-least-squares estimation theory. The proposed method was used to estimate the parameters of the AC power system simulator. It is shown that the unknown parameters are estimated with accuracy within 30 iterations. The method was modified to process the two or more kinds of transient phenomenon data simultaneously, and good results were obtained.

The results obtained are as follows : (1) Q is 2-16 in the subsurface soil layer. (2) Q is related to S-wave velocity in the equation : In Q=0.25+0.0066 Vs (m/sec), and to standard penetration test value in the equstion : In Q=0.79+0.022N. These equations may be useful for the estimation of Q for the underground layers. Sun, 30 Mar 1980 15:00:00 GMT http://hdl.handle.net/11133/567 1980-03-30T15:00:00Z
