Title: Controller for automatic transmission
Inventor: MORISAWA KUNIO
IPC: B60W10/101
Filed: 1986-06-11
Abstract: PURPOSE:To achieve a stable slip control on a low (mu) pavement by providing means for calculating the variation rate of the differential rotation between at least two wheels in four wheels and modifying the speed ratio pattern of transmission to the speed incremental side when the variation rate is higher than a predetermined level. CONSTITUTION:The variation rate of the differential rotation between two wheels detected through a rotation detecting means C is calculated by a variation rate calculating means D. When the variation rate is higher than a predetermined level, a speed ratio pattern modifying means E modifies a speed ratio pattern of a continuously variable transmission A being set by a speed ratio control means B to a speed ratio pattern at the incremental speed side. Consequently, the condition where the slip of wheel increases is obtained based upon the variation rate of the differential rotation so as to control the speed ratio of the transmission A earlier based upon the speed change pattern where the speed ratio increases.

Filed: 1995-06-02
Abstract: PURPOSE: To facilitate the removal of scale by a neutral electrolytic method and to economically produce a steel sheet having good surface characteristic by combindely considering two elements of a good descaling performance defined from the composition of steel sheet and an inferior descaling performance defined from annealing condition and applying annealing under a condition of giving the former superiority over the latter at the time of annealing a cold rolled Cr-base stainless steel sheet.

After annealing, the removing treatment of the scale is executed by electrolyzing the steel sheet in the neutral water solution of sodium sulfate, sodium nitride, etc., by using the conventional method and further, a pickling treatment for giving surface luster is applied. Then, at the time of annealing, when selecting the condition in which Q1 is larger than Q2 , the annealing time is short, so that the lower limit of the annealing time is made about 5-10sec in order to secure the sufficient annealing effect.
