  • Patent number: 5376058
    Abstract: A fluid pressure control arrangement for an automatic transmission comprises a control unit for calculating a shifting frequency and a determining a frictional coefficient of frictionally engageable elements of the transmission. Fluid pressure correction is calculated based on the shifting frequency and a throttle valve opening angle detected by a sensor. A signal indicative of the fluid pressure correction value is output to actuate a solenoid for effecting adjustment of fluid pressure in the automatic transmission for adjusting the line pressure in accordance with the determined frictional coefficient of the frictionally engageable elements to maintain sufficient engagement capacity of the frictionally engageable elements.

  • Patent number: 5269203
    Abstract: A control system for an automatic power transmission monitors atmospheric pressure and a throttle valve open angle. The system corrects the monitored throttle valve open angle on the basis of the monitored atmospheric pressure so as to compensate for a drop of engine output torque due to lowering of the atmospheric pressure. The corrected throttle valve open angle is used for performing shift control and/or line pressure control.

  • Patent number: 4362624
    Abstract: A strainer for paints or the like is proposed which comprises a main body portion and a filter plate portion, both carrying a filter cloth. When the filter plate portion is folded into the main body portion, there is left some space between the filter cloth on the former and that on the latter.
