Abstract: An interface circuit receives an input signal IN having a first voltage amplitude from a first circuit, and outputs an output signal OUT having a second voltage amplitude to a second circuit. A level shifter comprises a first CMOS inverter and a second CMOS inverter which are cross-coupled, and a current limiting circuit that limits a current that flows through the first CMOS inverter and the second CMOS inverter, and converts the input signal IN into an intermediate signal INT which is a differential signal. A latch circuit receives the intermediate signal INT from the level shifter, and switches its state according to the positive signal and the negative signal of the intermediate signal INT.

Abstract: A testing device for a torque converter having a turbine portion 2 and a stator portion 3, including a turbine shaft 4 rotatably supported by a first support portion 6, and a stator shaft 9 concentrically disposed on an outer circumferential side of the turbine shaft 4 and axially moveably and non-rotatably supported by a second support portion 8. The turbine shaft 4 has a central oil passage 4b and a splined portion 4a on the outer circumferential periphery which is engaged with a splined portion 2a of the turbine portion 2 when the turbine shaft 4 is axially downwardly moved. The stator shaft 9 has a splined portion 9d on the outer circumferential periphery which is engaged with a splined portion 3a of the stator portion 3 when the stator shaft 9 is axially downwardly moved. A spring 11 is provided, which biases the stator shaft 9 toward the torque converter.
