Title: Nozzle device for accelerating solid particle
Inventor: ANDORE BOTSUKU
IPC: C21C5/46
Filed: 1985-05-14
Abstract: An acceleration nozzle for particles entrained in a carrier gas comprises a first central nozzle having a first diverging cross-section, and an extension nozzle section extending from the first nozzle. The extension nozzle section has a flare or diverging angle which is greater than that of the first acceleration nozzle. The nozzle extension is surrounded about its mouth or opening by a second nozzle forming a casing or housing therearound; the second nozzle being connected to a source of gas. In a preferred embodiment, instead of utilizing two distinct gas sources to supply the first acceleration nozzle and the second "housing" nozzle, a portion of the gas passing through the acceleration nozzle may be diverted by means of slits built into the latter. The slits act as a separator of the gaseous phases and solid particles, and prevent the solid particles from penetrating the second nozzle. Acceleration nozzles of the present invention are typically used for delivering carboniferous powdered materials into a steel bath.

IPC: H01L27/115
Filed: 1990-04-20
Abstract: PURPOSE:To highly integrate and to write by forming a first impurity diffused layer as a drain, a second impurity diffused layer as a source, connecting the second diffused layer to all memory cells, and writing with MIS elements as being nonconductive state. CONSTITUTION:A metal-oxide-nitride-oxide semiconductor (MONOS) type nonvolatile storage element 12 is written by setting a substrate potential to the same potential as a source and a gate potential of the storage element 12 to a positive potential to the substrate potential to inject electrons into a gate electrode film from the substrate. Since a memory cell M12 on the same writing word line as that of a memory cell M11 is the same potential at a drain as a gate and a MIS element 13 is nonconductive, a drain 11 depleted layer is extended to a channel region to inhibit writing. This erasure is conducted by discharging electrons from a gate insulating film to the substrate by setting the gate potential to a negative potential to the substrate.

Abstract: PURPOSE:To improve the knot breakage strength and improve durability in use by using an eccentrically flat thread having a ratio between the larger and shorter diameters over a prescribed value, at least in one part of a wound thread. CONSTITUTION:An eccentrically flat thread 21 having a ratio between the longer diameter A and the shorter diameter B on the sectional surface of 1.5 or more is used at least as one part of a wound thread 20. At this time, only the eccentrically flat thread 21 may be used, or a thread 22 having a circular section which is used for the gut of a racket can be used together with the eccentrically flat thread 21. The sectional shape of the eccentrically flat thread 21 is an elliptical form like a collapsed circle, rectangular, or a rectangular form having R at four corners. The ratio between the longer diameter A and the shorter diameter B within a range of 1.5 to 3.0 is preferable in viewpoint of the improvement of the knot breakage strength of the gut, manufacture of the gut, handling, etc. In case of the ratio less than 1.5, the improvement of the knot breakage strength is not sufficiently developed. The tensile elongation of the eccentrically flat thread 21 which is larger than that of a core thread 10 permits the sufficient extension of the wound thread 20 in the knot part, and the breakage of only the wound thread 20 is prevented, and the knot breakage strength can be improved.
