Title: Charging method for raw material for blast
Inventor: KAJIWARA YOSHIO
IPC: C21B5/00
Filed: 1985-10-09
Abstract: PURPOSE:To eliminate the uneven presence of small lumped coke in an ore layer by dividing the small lumped coke to be mixed with the initial charge ore from the lumped coke, charging the same near the position where the initial charge ore falls and depositing the ore on the small lumped coke and charging the same at the 2nd and subsequent times. CONSTITUTION:First the lumped coke 2 is charged into a blast furnace 1, then the small lumped coke 3 is charged to the periphery of the position where the ore 4 is dropped in the stage of charging raw materials into the furnace. The initial charge ore 4 where the small lumped coke 3 is not mixed is then charged into the furnace to chip off the small lumped coke 3 and to mix the same with the ore 4 by the falling impact energy of the ore 4, thus forming a mixed layer of a wide range in the central part of the furnace. A large bell 5 is opened by charging the small lumped coke 3 into a large-bell hopper then depositing the 2nd and subsequent charge ore 4'' thereon. The small lumped coke 3 on a stationary plate 6 side is then discharged first and thereafter the ore 4'' in the upper part is discharged; finally the small lumped coke 3 on the large bell 4 side is discharged. The uneven presence of the coke 3 is thus suppressed.

Title: Method and apparatus for recording reproducing optical information
Inventor: NODA KAZUO
IPC: G11B7/09
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To prevent wrong signals from being recorded, by intermittently applying a driving voltage during a standby when recording or reproduction is not carried out, and executing focusing and tracking controls on the basis of light beams illuminated from an optical head. SOLUTION: While an AF control and an AT control are carried out also during a standby when neither recording nor reproduction is carried out, a laser light necessary for both controls is made equal in level to when information is reproduced. A power source 4 is required to output a voltage VR during the standby. The voltage VR is intermittently applied to a semiconductor laser 5 during standby so as to prevent light beam spots from recording wrong signals onto an optical card. Contacts 31 and 34 of a switch 3 are connected during the standby, and therefore a rectangular wave generated form a rectangular wave generator 2 is input from an input terminal 41 to the power source 4. The rectangular wave generated by the rectangular wave generator 2 is superposed to reduce the constant voltage VR at the power source 4.  As a result, the voltage VR is intermittently applied to the semiconductor laser 5.
