Title: Production of high-concentration aqueous coal slurry
Inventor: TAKEUCHI KAZUHIRO
IPC: C10L1/32
Filed: 1993-12-20
Abstract: PURPOSE:To efficiently obtain a high-concentration aqueous coal slurry excellent in ignitability and flammability by classifying a coal feedstock into coarse particles, small particles, and fine particles, pulverizing only the small particles with a low-concentration wet mill, and grinding the pulverized particles with a high-concentration wet mill along with the fine particles. CONSTITUTION:A coal feedstock is fed to a crusher 2 from a feedstock bunker 1. The crushed coal is introduced into a two-stage classifying apparatus 3, and classified into coarse particles 9a incapable of passing through the first classifier, small particles 9b which have passed through the first classifier but are incapable of passing through the second classifier, and fine particles 9d passed through the second classifier. The particles 9a are returned to the crusher 2 and recrushed. The particles 9b are introduced into a low-concentration wet mill 5 along with water and optionally with a surfactant 10 to wet-pulverize the particles 9b. The resulting slurry 9c is introduced into a high-concentration wet mill 6 along with the particles 9d and water and optionally with a surfactant 11 to pulverize the particles. The concentration of the slurry is then regulated. Thus, a high-concentration aqueous coal slurry is produced, which is stored in a slurry storage tank 8.

Abstract: PURPOSE:To improve synchronous detecting precision by locating light receiving elements for detecting an exposure starting position in a position non-equivalent to a scanning line and arranging a non-spherical lens for correcting aberration in a beam optical path and right in front of the light receiving element. CONSTITUTION:An SOS sensor 30 is arranged through a non-spherical lens 31 for correcting aberration far away from a position equivalent to a scanning line on a sensitized drum body 50.

Abstract: PURPOSE:To prevent a defective substrate from occurring by a method wherein a through-hole is provided on a substrate across one of two circuit wires whose both ends are connected in common to cut off the circuit wire. CONSTITUTION:A circuit pattern is formed on one face of an insulating substrate 1 with circuits wires 3 and 5 connected in parallel. The substrate 1 is overlapped with a mold 15 as performing a positioning to make a cut hole 29 overlap with the circuit wire 3, and a pin 25 is disposed upright in a support hole 21 of a mold 13, and the mold 13 is positioned as so to make the cut hole 29 coincide with the pin 25.
