Title: Enhancement of bulk density of substance to be charged in coke manufacture
Inventor: ADACHI TAKESHI
IPC: C10B57/04
Filed: 1980-01-11
Abstract: PURPOSE: To increase the bulk density of substance (coal) to be charged in a coke oven by a  method in which a hard molded coal and a soft molded coal are manufactured as molded coals  for mixing with raw material coal, and the soft molded coal is naturally pulverized during feed  process to obtain a grain size distribution with lesser intermediate grain size.  
     CONSTITUTION: A binder is added to a pulverized coal for molding and then molded by compression into a given grain size of molded coal, and then the molded coal obtained is mixed with raw material coal in a proper proportion and then charged into coke oven. In this case, a hard molded coal and a soft molded coal, each having different mechanical strengths, are manufactured and these molded coals are mixed during the feed process to the carbonization chamber of the coke oven and at the same time the soft molded coal is mainly naturally pulverized to obtain coal of a grain size distribution with lesser intermediate grain size; that is, the large size fraction of 2/3 or more of the grain size of the molded coal becomes 5W80wt%, the small size fraction of 2/9 or less of the grain size of the molded coal becomes 25W85wt%, and the remaining becomes an intermediate fraction of 2/3W2/9 of the grain size of the molded coal. Thus, the bulk density of the substance (coal) to be charged in coke oven can be increased.

Title: Optical scanner
Inventor: UIREMU HERARUDO OPUHEEIE
IPC: G11B7/085
Filed: 1989-01-09
Abstract: PURPOSE: To remarkably reduce the height of a scanner by arranging a reflection type diffraction grating on the downstream optical path of a collimator lens and using only sub-beams diffracted to a high order by the grating as the scanning beams. CONSTITUTION: The reflection type diffraction grating 4 is arranged between the collimator lens 8 and an objective lens 9. Then, an incident angle made by the normal line of the grating 4 and the principal beam of the scanning beams is remarkably changed from 45 deg.. Besides, the cycle and the incident angle of the grating 4 are set so that only the sub-beams diffracted to a high order by the grating 4 are passed through the lens 9. By properly selecting the diffraction order together with the incident angle, the grating 4 is made to function as the mirror of 45 deg. against the sub-beams of the selected order so as to reflect the sub-beams by 90 deg. against the incident beams. The height of the scanner is remarkably reduced by making the incident angle of the scanning beams larger than 45 deg. and smaller than 90 deg..
