Filed: 1983-12-21
Abstract: PURPOSE:To lower the lower limit of cooling water flow rate as lower as possible without reducing slit intervals at the outlet of a slit nozzle by specifying the ratio between the inlet slit interval of the nozzle and the outlet slit interval thereof. CONSTITUTION:A nozzle 8 is connected to the bottom discharging port of a water tank 4, and the inlet slit interval (a) at the discharging port side is made to >=3 times the outlet slit interval (b), and the space between these slits is formed into a taper one. That is, cooling water supplied to the tank 4 from the water outflowing holes 7 of a water supplying pipe 5, flows smoothly to the nozzle 8 with the aid of a flow regulating board 6, and an air is therefore prevented from flowing into the nozzle 8 even when the flow rate of cooling water is throttled.

Filed: 1990-09-17
Abstract: PURPOSE:To obtain a groove pattern shape having capacity sufficient for stably holding stripe magnetic domains by arranging the stripe magnetic domains through the use of ring-like groove patterns. CONSTITUTION:Upward magnetized area 10 exists in one stripe magnetic domain 3 surrounded by the ring-like pattern 1 and a leaking magnetic field where the magnetization of the area 10 operates in a direction where the stripe magnetic domain 3 stably exists. Thus, the stable existing range of the stripe magnetic domain 3 is enlarged. Since a boundary is surrounded by a non-magnetic groove, what is called a magnetic wall does not exist. When the magnetized state in the magnetized area 10 is set in the arrangement initial state of the magnetic domain, it does not change even if it gives little fluctuation of the magnetic field. Thus, the stable leaking magnetic field can always be obtained from the area 10 and the stripe magnetic domain 3 can stably be fixed.
