A method of determining a parameter of a liquid crystal cell is provided in which parameters, such as the thickness of the liquid crystal layer and the angle of the twist of liquid crystal molecule orientation in the liquid crystal cell, are accurately determined in a short time with a simple apparatus. Light from a light source 1 is transmitted through a polarizing plate 2 and incident to a liquid crystal cell 3. The light is transmitted by a polarizing plate 4 and the intensity of the transmitted light is measured by a photodetector 6. Then, the outputs of the photodetector 6 for the following cases are measured: when the polarization direction of the polarizing plate 4 is set (1) in the direction of the X axis, (2) in the direction of Y axis and (3) at 45 degrees to the X and Y axes and (4) when, with the polarization direction of the polarizing plate 4 being at 45 degrees to the X and Y axes, a quarter wavelength plate 5 is inserted between the polarizing plate 4 and the liquid crystal cell 3 so that its axial direction is tilted at 45 degrees to the polarization direction of the polarizing plate 4. Stokes parameters are obtained from the measurement values, and the thickness of the liquid crystal layer and the angle of twist of liquid crystal molecule orientation are calculated from the measured Stokes parameters.

The invention provides a torque feedback shift control device for an engine control system including an engine, an engine torque controller, an automatic transmission for changing output speed of the engine, and a transmission controller for controlling gear shifting in the transmission. A target torque generator is provided for generating a signal indicative of a target torque pattern in shifting of the automatic transmission according to a shifting signal from the transmission controller. A drive shaft torque detector detects an output torque of the automatic transmission, and the engine controller performs feedback control of the engine torque so that the output torque detected by the drive shaft torque detector in downshifting of the automatic transmission follows up the target torque pattern.

A zoom lens has a first group of a positive refractive power and a second group of a negative refractive power in sequence as seen from an object. The first group of the positive refractive power comprises a front group of a positive refractive power arranged to face the object and in front of an aperture iris and a rear group of a positive refractive power arranged between the aperture iris and an image plane. The rear group includes displacement means to drive it across an optical axis for vibration correction.

An internal focus super-telephoto zoom lens comprises, in succession from the object side, a first lens unit having positive refractive power, a second lens unit having negative refractive power, and a third lens unit having positive refractive power. During vari-focusing from the wide angle end to the telephoto end, the first lens unit is fixed relative to the image plane and the second lens unit and the third lens unit are moved on the optical axis thereof so as to narrow the air gap therebetween. The first lens unit has, in succession from the object side, a lens group having positive refractive power, a lens group having negative refractive power, and a lens group having positive refractive power. The lens group having negative refractive power is moved on the optical axis to thereby effect focusing. The super-telephoto zoom lens satisfies various predetermined conditions.
