Title: Photoelectron transfer device
Inventor: YAMADA AKIO
IPC: H01L21/30
Filed: 1988-04-28
Abstract: PURPOSE:To prevent discharge between a mask holder and an exposed subject by arranging a photoelectron emission surface of a mask of photoelectron transfer device to protrude toward the exposed subject from a holding surface of the mask. CONSTITUTION:A photoelectron emission surface 22a of a photoelectron mask 6a is arranged to protrude toward a wafer 7a from a holding surface 23a which is held by a mask holding 20. Since the distance between the wafer 7a and the holder 20 thereby increases, discharge to the wafer 7a is prevented thus improving throughput. On the contrary, as the distance (d) between the mask 6a and the wafer 7a becomes smaller, resolving characteristics can be improved.

Title: Inertia moment measuring device
Inventor: MATSUMURA ASAYUKI
IPC: G01M1/10
Filed: 1983-06-14
Abstract: PURPOSE:To execute a measurement with much higher accuracy than before, and also to improve remarkably the efficiency for measurement by providing a motor for rotating an object to be measured, and a means for measuring a time when this motor reaches a prescribed revolving speed. CONSTITUTION:An object to be measured 4 is placed on a motor 5 so that the rotation of the motor 5 is detected by a frequency generator 6, and its output frequency is converted to voltage by an F/V converter 7. When the motor 5 reaches some revolving speed and the frequency of the frequency generator 6 is F/V-converted, and when a time when its voltage becomes equal to voltage of a reference power source 8 is denoted by tx, in that case, an output of a comparator 9 is changed to ''Lo''. That is to say, no current flows to a constant-torque driving device 11. Therefore, basing on this time, this device measures the inertia moment of the object to be measured, and accordingly, the inertia moment can be measured with much higher accuracy than before.

Title: Controlling method for edging roll of strip mill
Inventor: TSUBOTA KAZUYA
IPC: B21B37/28
Filed: 1980-08-05
Abstract: PURPOSE: To improve the yield of products, by detecting the rolling loads of the left and right vertical edging rolls arranged on the run-out side of a horizontal roll pair, and by horizontally shifting the left and right vertical rolls correspondingly to the difference between the loads of said two rolls to be caused by a chamber of a rolled material.  
     CONSTITUTION: The rolling load detecting signals FL 1 , FL 2  sent from the load cells 9a, 9b arranged on both ends of the left vertical roll 3 are added by an adder 10a which then sends a signal FL to a subtractor 11. Similarly, a signal FR for the right vertical roll 3' is inputted to the subtractor 11. The subtractor 11 then operates the difference ΔF=FL-FR, and inputs the result to a central controller 12. If the result ΔF is positive, a shift signal +S is given to the left and right rolling reduction controllers 13a, 13b in order to simultaneously, parallelly shift two vertical rolls 3, 3' toward the left at the same velocity. If the result ΔF is negative, the said parallel shift is made toward the right. By the present constitution, the generation of a dog bone and an insufficient rolling reduction at both side edges of a rolled material is prevented.

The light becomes a circularly polarized light once through a 1/4 wavelength plate 19 and the light beam incident on the reflecting plate 20 is transmitted again through the 1/4 wavelength plate 19 and converted into a linearly polarized light in perpendicular to this paper. Thus, the light beam incident on the splitter 16 is made incident on the 2nd objective lens 18 and focus is formed to the 2nd recording medium face. Further, the light passes through the same path as the incidence and is reflected into a light beam 23.
