Inventor: MINEGISHI SEIJI
IPC: F16H1/32
Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To sufficiently form a lubricating oil film even in a small clearance by carrying out heat treatment of an internal roller material on which burnishing work is carried out, in a condition in which push-press chucking from all directions is released by a chuck machine, finishing is carried out on the outer periphery of the internal roller material on which heat treatment is carried out. SOLUTION: The center part of a cylindrical internal roller material 30 is cut roughly, and formed into a cylindrical shape. The outer periphery of the material 30 is chucked from all directions so as to generate nearly uniform push-press force on all circumferences by a chuck machine 50A having an inner circumferential shape corresponding to its outer periphery. In the chucked condition, burnishing work of the inner circumferential wall 32 of the material 30 is carried out. In a condition in which push-press chucking from all directions is released, heat treatment of the material 30 on which burnishing work is carried out, finishing of the outer periphery of the material is carried out. It is thus possible to form a lubricating oil film sufficiently even in a small clearance.

IPC: B62D117/00
Filed: 1993-06-21
Abstract: PURPOSE:To simply and appropriately adjust the deviation from the mounting error or the like of a sensor by obtaining the corrective quantity through addition/subtraction when the signal value of the yaw rate sensor is deviated from the neutral zero, and outputting the yaw rate corresponding to the rotational angular velocity of a vehicle by correction to be increased/decreased. CONSTITUTION:In a vehicle provided with a yaw rate sensor, a judgement whether or not the vehicle is stably traveling straight by the sensor signal and the vehicle speed is made, and when the vehicle is traveling straight, the value of the sensor signal is judged, and when the yaw rate value gamma is deviated to the right relative to the neutral zero, subtraction by the specified amount DELTAgamma is repeated until the deviation becomes zero, and the corrective quantity gamma' is calculated by the specified amount DELTAgammaand the number of subtraction. On the other hand, when the yaw rate is deviated to the left, addition by the specified amount DELTAgamma is repeated to calculate the corrective quantity gamma' in a similar manner, and the corrective quantity gamma' corresponding to the deviation of the mounting error of the sensor and the aging change or the like is calculated. Then, the yaw rate gamma is obtained by uniformly adding the corrective quantity gamma' to the signal value of the sensor gamma0. This constitution allows the correction of the yaw rate value gamma to be a correct one.

Abstract: PURPOSE: To improve the quality of regulating continuous rotational speed deviations of individual wheels in such a way that a reaction against the required rotational speed difference is produced, only when an additional effect can be confirmed by an electronic device and that the reaction against the rotational speed difference is produced, only when the required rotational speed difference continues for a long period of time. CONSTITUTION: When the rotational speed difference of any wheel obtained by an expression 'a vehicle speed VF-a wheel speed VR', is greater than approximate 10% of the vehicle speed VF and is unallowable, an internal counter 19 in a rotational speed difference evaluation circuit 16 adds up. On the contrary, when the difference is smaller than the approximate 10% and is allowable, the internal counter 19 is reset and the evaluation circuit 16 transmits a signal '0' to its output terminal. When the internal counter 19 records an unallowable rotational speed difference during a time T2 , for example, 16 sec, the evaluation circuit 16 transmits a signal '1' to the output terminal and a warning light is turned on for the wheel having the unallowable difference.
