Title: Interface cooling device of improved turbine rotor and turbine blade
Inventor: BORISU GUREZAA
IPC: F02C6/08
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To efficiently cool an interface between a disc and a blade by forming a cavity having a cross section reduced on the whole, from a first side toward a second side of the disc for the relation of root parts of a plurality of blades and a slot. SOLUTION: A cavity 90 formed on the whole between a space face 88 on a fir free shape 82 of a root part 76 of a blade 74 and a space face 66 of a slot 60 allows cooling fluid or cooling air to pass therethrough. The tapered (converged in the axial direction) cavity 90 between a disc 52 and the blade root 76 keeps heat dissipation rate controlled in the axial direction by an interface between the disc 52 and the blade 74 along a length of the whole axial cooling cavity 90. Consequently, a cooling air feeding device prevents a gas turbine engine from taking high temperature power gas into internal component elements to increase component life and efficiencies of the engine.

Title: Adhesive sheet
Inventor: FUJISHIMA YUKIHIRO
IPC: C09J7/02
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To easily peel a sheet adhered to a consumed product before the product is to be discarded, by forming an easily peelable part in at least a part of the edge of the adhesive sheet. SOLUTION: In an adhesive sheet 1 adhered to a consumable product to show instructions or the like of the product, an easily peelable part 2 is formed in at least part of the edge of the adhesive sheet 1. By this method, the adhesive sheet 1 is adhered to an easily visible place such as the back face of a toilet lid 11 of a hot-water flushing toilet 10. By forming the sheet above described, it is possible that when the consumed product is collected and discarded, the sheet thermally deforms and contracts by heating or the sheet changes its shape, and that the sheet automatically peels from the adhering surface of the consumed product. Thus, the peeling process of the adhesive sheet 1 can be completed without requiring manpower. Then the consumed product as it is can be carried to a specified discarding route.

Title: Solder bump formation
Inventor: YAMAMOTO NAOKI
IPC: H01L21/321
Filed: 1993-10-27
Abstract: PURPOSE:To utilize a polyimide film as a passivation film by not removing a resin film used as a spacer, represented by the polyimide film, after lift off but curing and shrinking the resin film by heat treatment thereby making the polyimide film thinner than a metal bump. CONSTITUTION:Heat treatment is conducted for about 1 hour in a nitrogen atmosphere at a temperature lower than the melting point of a Pb-Sn solder layer 17. Consequently, a polyimide film 14 shrinks by about 50% and the thickness thereof decreases to about 5mum. A solder bump 18 thereby becomes higher than the polyimide film 14. When the heat treatment is conducted at a temperature close to the melting point of low melting point solder composing the solder bump 18, the solder bump 18 is reflowed simultaneously with shrinkage of the polyimide film 14 thus producing a solder bump 18 deformed into spherical shape by surface tension.

Title: Desiliconizing method of molten iron
Inventor: KOTO BUNRO
IPC: C21C1/04
Filed: 1984-12-19
Abstract: PURPOSE:To utilize effectively the collected dust recovered from a converter as a desiliconizing agent in the stage of preliminary refining of the desiliconization of a molten iron by subjecting said dust to an oxidation treatment to increase the content of iron oxide. CONSTITUTION:The molten iron from a blast furnace is first desiliconized by preliminary refining prior to dephosphorization and desulfurization treatments. The desiliconization treatment is executed usually by blowing the collected dust from the converter and basic material such as CaO into the furnace through the tuyere thereof and oxidizing Si to desiliconize. However, the collected dust from the converter is spherical and is not angular like sintered ore and therefore such dust causes little damages to the tuyere but the dust contains much metallic iron and little iron oxide and therefore O2 is not enough for the oxidation of the Si. Such dust is therefore heated to 100-400 deg.C and is oxidized by a rotary kiln, fluidized bed, etc., so as to contain the iron oxide at the higher rate. Such dust is blown into the molten iron through the tuyere and the molten iron is desiliconized with high efficiency.
