Title: Method of charging coke oven with coal
Inventor: TAKAHASHI KIMIMICHI
IPC: C10B37/00
Filed: 1988-06-24
Abstract: PURPOSE:To produce coke with uniform quality at a low cost by forming a pressurizing passage in a hopper, and feeding coal in a compacted state through the pressurizing passage when a coke oven is charged with coal through the hopper having a turn table at its bottom. CONSTITUTION:At the bottom of a hopper 1 is installed a turn table 5 which rotates by a drive unit 4. At the center of the turn table is installed a cone 6 vertically extending upward. A side partition 7 extending from the side periphery of an exit opening 2 to the cone 6, and an upper partition 8 extending from the upper periphery of the exit opening 2 and connected both to the side wall of the hopper 1 and to the upper end of the side partition 7 are installed. Thus, a pressurizing passage 10 with a shape of an inclined tunnel and having an entry opening 9 with a larger cross sectional area than that of the exit opening is formed. Coal from a coal charge trunk is fed to a carbonizing chamber of a coke oven through the hopper 1 in a compacted state by utilizing the rotation of the pressurizing passage 10 and the turn table 5.

Title: Output circuit for solid-state image pickup device
Inventor: KAWAI MAKOTO
IPC: H04N5/341
Filed: 1994-07-08
Abstract: PURPOSE:To reduce power consumption of an output circuit by providing a switching means stopping the current of the output circuit in the resetting period of an image input signal in the output circuit of a solid-state image pickup device. CONSTITUTION:The source follower output circuit of the solid-state image pickup device includes an output power source Vdd1, drive Tr(transistor) 2, load Tr 3 and the switching means 7. One Tr, for example, can be used as the switching means 7. An inverted reset clock signal 21 obtained by inverting a reset clock signal 20 is given to the gate terminal of switching Tr 7. When Tr 7 is always in a conductive state, an output voltage waveform including reset noise 40a, a field through period 41 and a data period 42 is outputted from an output terminal 4. Since the inverted reset clock signal 21 is actually inputted to the gate terminal of Tr 7, Tr becomes a non-conductive in accordance with the reset period 40, the current of the output circuit becomes '0' in the reset noise period 40a and the power consumption of the output circuit is reduced.
