Abstract: A projection lens system for enlarging and displaying on a screen an original image from an image generating source, includes a first lens having positive refractive power, a second aberration correction lens, and a third lens, positioned nearest the image generating source and having a concave lens surface thereof facing the screen. The third lens has a profile such that its refractive power at a marginal area adjacent a peripheral edge thereof is less than its refractive power at an area adjacent an optical axis of said projection lens system. The surface of the third lens facing the image generating source is in contact with a cooling liquid which cools the image generating source.

Abstract: A grinding head unit is constituted by a grinding wheel, a drive device for rotating the grinding wheel, and a movement device for moving the grinding wheel. When vibration of a mill roll is applied to the grinding wheel, a plain wheel integral with an abrasive layer of the grinding wheel and having an elastically deforming function is deflected to absorb the vibration energy. The contact force between the abrasive layer and the mill roll is measured for determining a profile of the mill roll. The mill roll can be thereby ground into a target profile while absorbing the vibration transmitted from the mill roll and measuring the profile of the mill roll, without causing any chattering marks.

Abstract: Upper and lower working rolls 2a, 2b are ground while moving respective grindstone devices 3a, 3b in reverse directions, whereby the region of grinding for the upper working roll 2a and that for the lower working roll 2b are maintained in symmetry with respect to the center of rolls, one on the operating side and the other on the driving side. By this arrangement, it is possible to equalize the coefficients of friction on the operating side and the driving side, and to prevent meandering of the rolling stock 6 as well as drawing (squeezing) or bad product shape due to the meandering from occurring. The timings to start grinding by the grindstone devices 3a, 3b are set to be substantially the same, and the velocities of movement of the grindstone devices 3a, 3b in the axial direction of the working rolls are set to be equal, whereby the difference in frictional coefficient due to grinding in the longitudinal direction of the rolls can stably be kept small.

A means used to control the surface roughness introduces into the film growing chamber oxygen, nitrogen, hydrogen, or a gas mixture thereof into a vacuum of 10−6 Torr to 10−9 Torr, reduces the substrate temperature to 0° C. or lower during film growth, or oxidizes an underlayer. The lower electrode layer material used is a film laminate of a high-permeability amorphous magnetic material and a non-magnetic metallic layer.
