IPC: B22D37/00
Filed: 1981-02-23
Abstract: PURPOSE:To prevent the knocking in of inclusions or the like owing to molten steel flow and to obtain clean steel in good yields by making the sectional inside diameter of the part corresponding to the molten steel level in the lower part of a long nozzle larger than the inside diameter of the molten steel flow passage in an opening-closing device for a ladle. CONSTITUTION:The upper part 10a of a long nozzle 10 for continuous casting is formed to a straight cylindrical body of a proper size, and the lower part 10b is formed to such a straight cylindrical or a truncated conical shape which, when said part is immersed in the molten steel 4 in a tundish, the inside section of the part corresponding to the molten steel level L includes the inside diameter size R part l.5-5 times the inside diameter of the molten steel flow passage of the sliding nozzle provided to a ladle 1. If such nozzle 10 is immersed into the molten steel 4 in the tundish and the molten steel is charged, the knocking of the slag layer 5 floating on the surface of the steel into the steel 4 by the charging flow is obviated. Also, the blow out of the molten steel from the joining part 11 of the nozzle 10 which occurs on closing of the bottom end of the nozzle 10 is fully prevented.

Title: Information reproducer
Inventor: TANAKA SHINICHI
IPC: G11B20/10
Filed: 1984-02-14
Abstract: PURPOSE:To read accurately and stably the information even from a reproduction signal having a change of the duty ratio by giving the digital control to said duty ratio. CONSTITUTION:The 1st and 2nd reversible counters 20 and 21 counts forwardly the clocks phi when a reproduced digital signal is kept at level H and then count adversely those clocks when said digital signal is kept at level L respectively. If the duty ratio of the digital signal is larger than the normal value with a longer time set for level H than level L, the counter 20 increases its number on an average and produces a carry signal at an output terminal C. This signal C is supplied to the counter 21 as a ripple clock through an input terminal RC. The output signals Qi, Qj and Qk given from the counter 21 undergo the D/A conersion and are immediately fed back to threshold. This can improve the shift of the duty ratio of the reproduction digital signal.

Title: Assembling method for ladder type piezoelectric filter
Inventor: IWATA TATSUO
IPC: H03H9/58
Filed: 1994-01-28
Abstract: PURPOSE:To fill up a clearance generated at the time of bending, and to prevent the intrusion of moisture by packing the first insulation resin layer at a case opening part, bending a terminal board leg part, and sealing the case opening part with the second insulation resin layer. CONSTITUTION:A first insulation resin layer 9 is packed and hardened in the opening part of a case 8. Afterwards, when leg parts 3b and 4b are bent like a crank (from chain lines to solid lines), the contact part of the inside edge of the leg parts 3b and 4b with the resin layer 9 peels off due to a stress distortion added to the inside edge side of the leg parts 3b and 4b, and a void (s) is generated. The void (s) is filled up with a second insulation resin (epoxy resin or the like) layer 10 formed after bending, and disappears. Thus, an opening part 8a can be exactly sealed, and the intrusion of the moisture can be interrupted. Then, a piezoelectric filter formed like this is surface mounted on the upper face of a printed circuit board.
