Title: Method and device for separating nonmagnetic material and molding sand
Inventor: MIYASHITA YOSHIO
IPC: B22D29/00
Filed: 1984-01-10
Abstract: PURPOSE:To improve considerably the rate of recovering respective components by disintegrating only the molding sand of lumps in which the molding sand and a nonmagnetic metal present mixedly under specific conditions and separating the nonmagnetic material of the large lumps then screening the nonmagnetic material of the small pieces and the molding sand. CONSTITUTION:A body 8 of a rod mill provided with a grate liner chamber 10 having a blind plate chamber 9 and a long hole 19 and a chamber 11 having a square hole 18 of a large diameter is rotated by a driving roller 14. The lumps in which the molding sand and nonmagnetic metal formed naturally are mixed are charged into the body 8. Only the molding sand is disintegrated by specifying the number of revolution of the body 8 at 40-60% of the upper limit number of revolution and the packing rate of a disintegrating medium at 7-30%. The disintegrated molding sand disintegrated in such a way and the nonmagnetic metal of small pieces are passed through the hole 19 and are taken out of a discharge port 16, then the molding sand and the nonmagnetic metal of the small pieces are separated by screening. On the other hand, the nonmagnetic metal of the large lumps is discharged through the square hole 18 to a discharge port 17.

Title: Color correction exposure system for photosensitive medium
Inventor: ERITSUKU KAARU NERUSON
IPC: G03F7/20
Filed: 1990-01-09
Abstract: PURPOSE: To correct color without increasing an irradiation time by arranging a reflecting surface having larger light reflectivity within the range of a selected wave length band than outside of the range at a side corresponding to a back surface of a photosensitive material support. CONSTITUTION: A supporting fixed plate 37 is arranged at the lower side of an exposure of a sensitive medium 10 in an exposure station 38 and the supporting fixed plate 37 is provided with the reflecting surface 50. The reflecting surface 50 is selected to have the larger light reflectivity in wave length within the range of the selected wave length band than in that outside of the range. During exposure, light from a radiation ray source 22 passes a microcapsule on the front surface of the medium 10 and a part of radiation rays is absorbed. A large quantity of radiation rays pass through so as to be reflected on the reflecting surface 50 and, then, pass through the microcapsule by another route.  Since the radiation rays add a most part of light within the selected wave length band, this additional exposure gives influence on the color containing quantity of exposure in the sensitive medium as a whole. Thus, color is corrected without deteriorating the film forming speed of the medium.

Abstract: PURPOSE: To enhance wettability of a surface of a woody material and improve adhesiveness of an adhesive, by preliminarily applying corona discharge treatment to the woody material to be subjected to an adhesion process.  
     CONSTITUTION: The corona discharge treatment is preliminarily applied to a woody material with bad adhesiveness because a surface property thereof is inferior and, thereafter, the adhesion is carried out. The corona discharge treatment is carried out by a method wherein electric discharge is generated between two electrodes by a high- voltage power source under an atmospheric pressure and said material is made to pass through the electric discharge atmosphere. As the high-voltage source, a high- frequency power source is used and said treatment is carried out by applying a voltage of about 5W50KV. The woody material is passed through the electric discharge section at a constant treating speed on a roller or a belt. The degree of said treatment, that is, a discharge treatment amount is calculated by a formula: discharge treatment amount =W/V×L(W.min/m 2 ) and can be arbitrarily regulated by the treating speed V(m/min) and power source output W(watt).

Abstract: PURPOSE:To accurately measure water content over a wide range by arranging a fast neutron source on the side opposite to a fast neutron detector with respect to a hopper and detecting a transmitted fast neutron by the fast neutron detector. CONSTITUTION:When the water content of the object to be measured in a hopper 2 is in the vicinity of 0%, the fast neutron emitted from a fast neutron source passes through the hopper 2 without being decelerated to be measured by a fast neutron detector 4 and, when the water content increases, the fast neutron from the fast neutron source 1 is decelerated and the signal detected by the fast neutron detector 4 is reduced.
