Title: Pneumatic type fuel injector for cylinder of internal combustion engine
Inventor: PIEERU DEYURE
IPC: F02B75/02
Filed: 1988-11-28
Abstract: PURPOSE: To allow large quantity of fuel to be inducted to a chamber of a cylinder by arranging two orifices communicating with the chamber of the cylinder in a fuel injection chamber, associating a valve with each of the orifices and arranging two outlet channels each directed towards one of the two orifices. CONSTITUTION: When valves 5a, 5b are closed simultaneously, compressed air flows into a fuel injection chamber 3 in the direction of an arrow 15 at high speed. The compressed air flows into nozzles 14a, 14b, is further accelerated there, nebulizes the liquid fuel conducted to the chamber 3 from a fuel injector 8 and becomes jets 12a, 12b. The compressed air containing floating nebulized fuel flows into a chamber of a cylinder. When fuel is injected, the valves 5a, 5b are opened simultaneously, the heads of the valves 5a, 5b depart from valve seats surrounding openings 4a, 4b. Thus, the flow cross-section of the floating nebulized fuel contained in the compressed air is two times as large as the flow cross-section of one valve. As the weight and inertia of the valves 5a, 5b are not large, the device applies in particular to high power engine.

IPC: A61K8/00
Filed: 1994-12-05
Abstract: PURPOSE:To obtain the subject foaming composition having an excellent cooling effect without giving a bitter taste to the tongue or causing a bur in the throat by using a specified ratio of a foaming agent capable of generating CO2 when dissolved in the mouth, an endothermic substance and 1-menthol included in or adsorbed on a degradated starch in combination. CONSTITUTION:This solid dental foaming composition is composed of 0.5 to 40wt.% foaming agent capable of foaming C02 when dissolved in the mouth, 50 to 98wt.% adsorbent capable of allowing in endothermic reaction to take place when dissolved in the mouth and 1-menthol included in or adsorbed on a degradated starch in which the amount of 1-menthol is 0.02 to 20wt.% based on the composition, capable of acting on the coating of tongue and the periglottis and giving a cool feeling to the inside of the mouth and useful in the fields of quasidrug, cosmetic, food, etc. As the foaming agent, e.g. a combination of a carbonate (e.g. potassium bicarbonate) and an organic acid (e.g. malic acid) is preferably used. As the endothermic substance, e.g. a crystalline xylylate is preferably used. As the 1-menthol component, a natural essential oil such as peppermint oil included in or adsorbed on a degradated starch such as porous dextrin is used.

Title: Nut for burying
Inventor: SUMIYA TOSHIHIKO
IPC: F16B37/04
Filed: 1989-11-17
Abstract: PURPOSE:To prevent the screw from loosening at the time of screwing the screw tool by bending the metal sheet, forming the nut main body with binding the both side peripheral edges each other, providing the bent back part at the rear end, punching and forming the female screw part on the inside surface of the nut main body and inserting the insert-pushing tool to enlarge the diameter of the bent back part. CONSTITUTION:The bent back part 2 is formed by bending back the rear end of the nut main body 1 which is formed by bending the metal sheet in nearly cylindrical type curved shape. The bent back part 2 is made thicker than the other parts of the nut body 1, accordingly, when the diameter of the bent back part 2 is enlarged with inserting of the insert-pushing tool 5, it is bitten in the inside surface of the hole 6, so if the female part 3 of the nut main body is screwed with the screw tool 7, the high strength resistant to pulling can be achieved. And because the metal sheet is bent in the nearly cylindrical type curved shape and the both side peripheral edges are also bound each other with the diameter enlargement preventing means B and the nut main body 1 is formed, so if the female screw part 3 of the nut main body 1 is screwed with the screw tool 7, the both side peripheral edges of the nut main body 1 are not mutually enlarged, and even if the large pulling force acts, the screw is prevented from loosening and from falling out.

Title: Diaphragm corrosion-resistant material for ultrasonic pickling
Inventor: EBARA RYUICHIRO
IPC: C22F1/00
Filed: 1989-11-21
Abstract: PURPOSE:To improve the pickling effect in a diaphragm and to reduce the damage in itself by adding a specified amt. of Pd into a Ti-Al-V alloy having a prescribed compsn. CONSTITUTION:Pd, 0.05 to 0.2%, is added to a Ti-6Al-4V alloy of a diaphragm corrosion-resistant material. The Ti-6Al-4V-Pd plate-shaped alloy is hot-rolled at 900 to 950 deg.C to refine the crystalline grains in the material, by which its corrosion resistance is improved. Next, the alloy is heated to 900 to 960 deg.C, is held for about 1.5 hr and is thereafter water-cooled. After that, the alloy is heated to 540 to 600 deg.C, is held for about 5 to 7 hr and is air-cooled, by which its corrosion resistance and cavitation erosion resistance are improved. In this way, a diaphragm can be worked safely to a sufficient degree in ultrasonic pickling.

Title: Dephosphorization of molten iron
Inventor: MIYATA MASAKI
IPC: C21C1/02
Filed: 1994-12-05
Abstract: PURPOSE: To provide a high efficient dephosphorizing method of molten iron at a low cost. CONSTITUTION: At the time of dephosphorizing molten iron with oxygen top- blowing by using a flux for dephosphorization mainly consisting of converter slag and iron oxide in a top-bottom combined converter type furnace, the slag condition under treatment is adjusted so as to satisfy a basicity (%CaO/% SiO2 )=1.2-2.0, (Al2 O3 )=2-16%, and (T. Fe)=7-30%. Further, (%F) in the slag is controlled to <=2%, and continuous casting slag in steel and/or ingot-making slag can be used as Al2 O3 source. By this method, dephosphorizing treatment without adding CaF2 to the flux can be executed and reduction in the cost of producing the low phosphorus molten steel can be achieved. The slag after treatment can be used to roadbed material, etc., by abbreviating its aging.

Title: Ink ribbon cassette and method for using ink ribbon cassette
Inventor: MATSUNO OSAMU
IPC: B41J32/02
Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To eliminate flow-out of an endless ink ribbon carelessly to an exterior and overturn of the ribbon in a ribbon storage part at the time of transporting by providing a ribbon storage case for folding and containing the ribbon before using, and partly locking the case in a cassette case. SOLUTION: A ribbon containing case 4 for folding and feeding an ink ribbon 2 in advance into a ribbon container 3 of a cassette case 1 is locked to a locking unit 6. Since the ink ribbon cassette of this constitution has the box- shaped ribbon storage case 4, a special cover or a ribbon overturn preventing stopper is eliminated. Thus, the ribbon 2 is not sprung out before mounting. Further, even if a lengthy ribbon is in the container, the cassette in which the ribbon is not overturned at the time of transporting or not failed to be fed can be obtained.
