Title: Wire cut discharge working unit
Inventor: TANAKA YUTAKA
IPC: B23H7/04
Filed: 1978-01-30
Abstract: PURPOSE:To provide the title discharge working unit by which efficient working can be carried out by automatically setting the electrical condition to the optimal value with an operation amplifier. CONSTITUTION:Working voltage Eg is compared to reference voltage Eo, and feeding speed F to working is so varied that voltage Eg approaches the value of voltage Eo. The variation of speed F is so controlled that the voltage between wire electrode 1 and product 2 to be worked is kept constant against a change in plate thickness. Accordingly, if the electrical condition is made constant, working energy is kept almost constant. So, working area speed is also kept almost constant and speed F is reduced in inverse proportion to the plate thickness. Speed F is inputted in operation amplifier 13 at this state. As speed F is reduced, output voltage K(Fo-F) of amplifier 13 is raised, and hence the electrical condition is increased and speed F is not so reduced. Fo represents reference feeding speed and K a proportional constant.

Title: Coal bunker
Inventor: HOSHINO TERUO
IPC: B65D88/26
Filed: 1997-01-22
Abstract: PROBLEM TO BE SOLVED: To prevent a coal bunker in a pulverized-coal manufacturing facilities from being blocked, by connecting a bunker shoot to a main body lower part so that the axis of the bunker shoot is out of the axis of the main body lower part in a horizontal direction. SOLUTION: To the lower end of the main body upper part 35 of a cylindrical coal-bunker 34 having a specific diameter, a main body lower part 36, which is hollow and has the shape of a truncated, inverted corn, is coaxially connected, and a cylindrical bunker shoot 37 is so connected to its lower end as to be slightly out of the axis of the main body lower part 36. Therefore, because, around the outlet of the main body lower part 36, the effects of a difference in inclined-surface length between four sides near the outlet of the main body lower part 36 and a change in cross-sectional shape from the main body lower part 36 to the bunker shoot 37 and a slow change in cross-sectional-area reduction rate are exerted, the flow of falling raw coal becomes ununiform near the outlet of the main body lower part 36, and also a high consolidation can be prevented.  This restricts the occurrence of a bridge of raw coal and prevents the coal bunker 34 from being blocked.
