Title: Material matching apparatus and method for photography
Inventor: AANESUTO OORIHI
IPC: G03B27/62
Filed: 1988-12-07
Abstract: PURPOSE: To eliminate an air pocket which is formed on a sheet and which causes the distortion of a photographic image by establishing pressure difference crossing a film so that an elastic supporting state is resisted and selectively reducing pressure in a pressure chamber. CONSTITUTION: By an air inlet 21, the velocity of the air of high air pressure flowing toward the second chamber 20 formed on the lower side of the flexible film 15 is restricted. Therefore, the flow velocity of the air of the high air pressure passed through the inlet 21 toward the chamber 20 becomes lower than that of air released 24 (by a vacuum pump) from the first chamber 19. Then, the pressure difference crossing the film 15 is maintained among the film 15, the sheets 9 and 11 and an exposure plate 13 in a state where the contact of the air is gradually moved, that means, widened toward the periphery of the film 15 from the central position of the inlet 21. For example, the air is gradually released from the chamber 19 through an outside boundary wall near the circumferential edge of the film 15. Thus, the air pocket causing the distortion of the photographic image is not left.

Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of camber even after shearing a blank and a large plate by obtaining a condition, in which the camber does not generate in the finish worked part even after shearing treatment and deciding this condition as a leveling condition. SOLUTION: The camber amount after shearing the large plate is calculated based on a preliminary leveling condition, a condition before leveling a coil and a shearing condition of the large plate. When the calculated value is in a reference value, the camber amount at the time of producing the blank from the above preliminary leveling condition and the blank shearing condition. When this value is in the reference value, the actual coil is leveled in this preliminary leveling condition to produce the large plate by using a shearing machine 30. When the camber amount measured with a camber detector 10 is within the reference value, the blank is produced by using the shearing machine 30 from the large plate. When the camber amount of the blank measured with the camber detector 10 is within the reference value, the preliminary leveling condition is decided as the leveling condition.  In the case of being out of the reference value in the above each step, the condition is changed and the same operation is repeated.

IPC: H01S5/00
Filed: 1986-12-25
Abstract: PURPOSE:To suppress the variation of an energy shift rate caused by a small fluctuation of a well width substantially by a method wherein the potential energy distribution along the direction of lamination of a well layer (a layer with a smaller band gap in a quantum well structure which constitutes an active layer) has a parabolic shape. CONSTITUTION:The potential energy distribution along the direction of lamination of a well layer (a layer with a smaller band gap in a quantum well structure which constitutes an active layer) has a parabolic shape. In other words, as the well layer 2 has the parabolic energy distribution and nearly equal spacings are provided between the energy levels 3 and 4 of the electrons in the well, the energy level is in reverse proportion to the well width Lz. With this constitution, the rate of the variation of the energy levels 3 and 4 corresponding to the fluctuation of the well width can be suppressed substantially compared to a conventional MQW-LD.
