Title: Flow control solenoid valve
Inventor: ANDOU FUMITAKA
IPC: F16K31/08
Filed: 1980-09-04
Abstract: PURPOSE: To allow linear flow control of a solenoid valve with a computor, by a method wherein arranging two permanent magnets with their surfaces of the same polarity facing each other and making relation between applied voltage and displacement of both magnets to be linear.  
     CONSTITUTION: When power supply is connected to the solenoid coil, and a certain voltage is achieved, attractive force acting on the moving core by exciting the solenoid coil overpowers the repulsive force of the permanent magnet and the valve separates from the valve seat, together with moving core and stops at the position where attractive force of solenoid coil and repulsive force of the permanent magnet balances. Namely, the gap between the valve and the valve seat changes in proportion to the applied voltage. Because the fluid passes through holes a, b, c, d, e and the flow rate via a through hole 2 is proportional to the cross sectional area of the valve seat, and the linear control of flow can be performed by a computor.

Filed: 1992-05-15
Abstract: PURPOSE:To provide an automatic sliding nozzle closing method in which both functions of the prevention of flow-out of molten slag and the reduction of remaining steel in a ladle are compatible with each other. CONSTITUTION:The molten steel in the ladle is poured into a tundish in the protective atmosphere through the sliding nozzle. At the last stage of pouring, slag mixing ratio is measured with a slag mixing ratio measuring sensor 6A arranged around an upper nozzle to discriminate the level of mixing ratio with a slag flow-out detector 6. Then, within the range of 2-10% slag mixing ratio, close pulse and open pulse are alternately and repeatedly generated with a pulse generator 7 to execute the control of narrowing opening degree of the nozzle with a sliding nozzle opening/closing controller 3A. There-after, with in the range of 10-30% slag mixing ratio, the nozzle closing is executed with a close continuing signal. By this method, the omission of slag-watching work, the prevention of flow-out of the slag, the improvement of casting yield caused by reduction of the remaining steel quantity and the reduction of defect in the steel quality can be attained.

Filed: 1990-05-14
Abstract: PURPOSE:To reduce drag torque by forming a passage, which is for supplying air to contact surfaces of both plates, in at least one of the drive plate or the driven plate. CONSTITUTION:In the case of a large rotational speed of a drive plate 12, centrifugal force, acting on lubricating oil 24, is also increased, so that the lubricating oil exceeds a supply amount by increasing a flow speed of the lubricating oil 24. Under this condition, air is started to infiltrate between both plates 12, 14 from a side of the stationary plate 14 by generating a negative speed and exfoliation of the lubricating oil 24 in a side of the driven plate 14, and air and the lubricating oil 26 are violently mixed and discharged in the peripheral direction by a flow in the vicinity of the rotating plate 12. In this way, drag torque is reduced by decreasing a drag of the lubricating oil 24. Here, an inflow of air is easily generated along a groove 22 between the plates 12, 14 by forming the groove in the plate 14, and the air is mixed in the lubricating oil 24 from a region of small relative rotation between both the plates.
