IPC: H03H9/25
Filed: 1991-11-29
Abstract: PURPOSE:To enable a surface acoustic wave device to carry out distinguished spurious suppression by using particular lithium monocrystal substrate to make the rotary Y-cut surface propagate surface acoustic wave. CONSTITUTION:A lithium tetraborate monocrystal is prepared. From this monocrystal body a substrate A having the Y-cut surface obtained by turning the crystal body by a rotational angle of 60 deg.-90 deg. around the X-axis is cut out, and electrodes and so on are prepared to form a surface acoustic wave device.

Title: Submerged nozzle for continuous casting
Inventor: HOSOYA KOJI
IPC: B22D11/10
Filed: 1987-12-16
Abstract: PURPOSE:To improve the quality of a cast slab by reducing the cross sectional area of molten steel passage in a submerged nozzle toward the lower part, forming discharging holes at the upper part and the lower part thereof and specifying the cross sectional area of the discharging holes and the molten steel passage. CONSTITUTION:The cross sectional area for the molten steel passage 3 in the submerged nozzle 1 is formed as reducing to the sectional areas S1, S2...Sn in order from the upper part and the discharging holes 2 having the cross sectional area s1, s2...sn are arranged in order at upper part and lower part of each reduced part. Then, coefficient of discharge K is set to 0.7<=K<=1.0 and the cross sectional area S1-Sn for each passage 3 and the cross sectional area s1-sn for each discharging hole 2 are set so as to satisfy each equation based on the consecutive equation and Bernoulli's equation. By this method, as the discharging speed of the molten steel from each discharging hole s1-sn in the submerged nozzle 1 is almost uniformized, the invading depth of the molten steel flow into the inner face in the cast slab is made to shallow and the enclosure of the inclusion is reduced. Therefore, the quality of the cast slab is improved.
