Abstract: A hydraulic controller of an automatic transmission which releases the lockup clutch when it fails. An output port of a solenoid valve is connected to a port of a lockup control valve and a port of a garage shift valve. An output port of a solenoid valve is connected to a port of the lockup control valve and a port of the garage shift valve. At least one of the solenoid valves is freely duty-controlled. A pattern, which enables regular control of the automatic transmission in normal operation and does not allow the lockup clutch to change from its released state to its engaged state, is selected for use from among plural combinations of signal pressures of the solenoid valves.

Abstract: When the modulation speed of the laser is increased, it is difficult to correctly detect a peak power and a bias power for controlling a laser power. The bias power current Ib is controlled by the operated value of the operation circuit 3 in accordance with the reproduction power current Ir control value of the servo amplifier 5 at the reproduction just before recording, and as for the erase power Pe, since its period is relatively long, the power is detected by the sample-hold circuit 4 and the erase power current Ie is controlled by the operation circuit 3, and the peak power PP is controlled by the operated value of the operation circuit 3 in accordance with the erase power current Ie, and therefore, a bottom hold circuit and a peak hold circuit are not required and the laser control apparatus which does not require the high-speed performance in a photodiode and a monitor circuit is realized to solve the above mentioned problem.

Abstract: At the time of starting a vehicle, the torque capacity of a friction engagement element is made less than the torque capacity of a continuously variable transmission by setting a ratio between the pressure-receiving area of a control oil chamber (77a) of a garage shift control valve (77) and the pressure-receiving area of a feedback chamber (77d) of the valve, and a ratio between the pressure-receiving area of a control oil chamber (73a) of a secondary sheave control valve 73 and the pressure-receiving area of a feedback chamber 73d of the valve. This allows a control based on a single linear solenoid valve SLT although the control is for eliminating slip of a belt of the continuously variable transmission. Therefore, the construction of the oil pressure control apparatus is simplified so that the size and cost thereof can be reduced.

Abstract: For achieving a high accuracy line pressure control and a high line pressure, a valve control system outputs a first signal pressure to a primary regulator valve as a second signal pressure when the first signal pressure is low. The valve control system outputs a gain pressure higher than the first signal pressure to the primary regulator valve as the second signal pressure when the first signal pressure is high. A change amount of the line pressure from the primary regulator valve concerning with a change amount of the first signal pressure is a gain. The gain is a low gain which increases the accuracy of the line pressure control when the first signal pressure is low, and the gain is a high gain with which the high line pressure is output when the first signal pressure is high.

Abstract: A control valve is shown for a continuously variable transmission, with a spool of the control valve being maintained at a fixed transmission ratio position between an up-shift position and a downshift position when a signal pressure supplied to the control valve falls within a certain range. The signal pressure is provided to the control valve through a pressure line that is divided, with one branch of the signal pressure line being connected to a first input port of the control valve and the other branch being connected to a second input port through an orifice. Application of a signal pressure within a certain range results in the drain port being selectively connected with the second input port.
