Title: Helicopter
Inventor: SUGIYAMA KATSUMASA
IPC: B64C27/04
Filed: 1992-05-06
Abstract: PURPOSE:To prevent separation of air flow so as to enhance the performance of a helicopter having a wide front body and a narrow rear body by adding a fare ring in the portion of the helicopter where the cross section of the body is suddenly varied, thus smoothing variation in the cross section. CONSTITUTION:A fare ring 9 made from foaming material or lightweight composite material is added in the portion of a body 5 where its cross section is suddenly varied and so there is a flow of air 11 that does not separate while air resistance is decreased. Therefore, the performance of the helicopter is enhanced while vibration and noise caused by separation of air flow are prevented. Comfortableness for passengers is thus improved while the problem of noise pollution to the neighborhood is solved. In addition, an outer plate may be provided in place of the fare ring 9 and a bag for sealing light gas may be provided therein or a vane may be added or an air blasting device provided to provide similar effects.
Patent JP-H0411322-A (JP)
Title: Magnetic recording medium
Inventor: HIBINO KUNIO
IPC: G11B5/72
Filed: 1990-04-27
Abstract: PURPOSE:To prevent deterioration of durability by forming a hard carbon film having pin holes of 5000-25000000/cm<2> density. CONSTITUTION:On a nonmagnetic substrate, there are successively formed a ferromagnetic metal thin film 2, hard carbon film 3 and lubricant 4 to constitute the magnetic recording medium. The hard carbon film is made to have pin holes, and it is effective to provide pin holes of 5000-25000000/cm<2> density in the hard carbon film. Therefore, the lubricant permeates in the pin holes, and even when the lubricant decreases in amt. from the hard carbon film surface by repeated traveling, the lubricant in the pin holes oozes to the surface to avoid decrease of the lubricant on the magnetic layer surface. Thus, deterioration of durability can be prevented.

IPC: H01T4/04
Filed: 1987-05-11
Abstract: PURPOSE:To obtain an arrester which is provided with structure simpler than that of a conventional one and equivalent to the conventional one in its heat- radiating characteristics, by interposing heat-radiating fins, which are larger in their diameter than elements, between respective elements of zinc oxide and filling a hermetical container of porcelain with a gas which is large in its coefficient of thermal conductivity and high in its stability. CONSTITUTION:Heat-radiating fins 4 made of metal such as aluminium, good in its heat conductivity, are interposed to laminate elements 3 made of zinc oxide on a multistage state so that an element block 2 is composed and housed in a porcelain container 1 which is hermetical. The element block 2 is electrically connected with a line terminal 5 and an earth terminal 6 through caps 7. Further, a gas 9 of 0.1 Kcal/mh deg.C (room temperature) or more in its coefficient of heat conductivity, for example, a helium gas is sealed in a space part 8 which is inside the porcelain container 1 and exclusive of the element block 2. Heat-radiating characteristics of this arrester are hence improved, and resultingly a temperature of each zinc oxide element serving as an internal ingredient is lowered and absorptive ability of surge energy is also increased.

Title: Reducing sulfur dioxide
Inventor: MURONAKA YOSHIHIRO
IPC: B01J23/74
Filed: 1978-09-18
Abstract: PURPOSE: To prevent public pollution and to save resources by effecting relatively low temperature reduction with prolonged catalyst service life, sulfur dioxide is reduced together with hydrocarbon by using reducing catalyst of metal oxides such as copper carried by γ-alumina carrier.  
     CONSTITUTION: Sulfur oxide containing gas 1 from petroleum plants or the like is mixed with reducing gas 2 of hydrocarbons having 1W8 carbons such as methane and ethane. The mixed gas is introduced into the catalytic reactor 5 and reduced by reducing catalyst consisting of γ-alumina incorporated with at least on oxides of copper, silver, and zinc. The gas is passed through the reducing catalyst at a reaction temperature from 450 to 800°C and contacted for 0.36W3.6 seconds. This causes sulfur oxide reduction by hydrocarbon to form sulfur and hydrogen sulfide. The process, thus, is effective at a relatively low temperature, reducing sulfur dioxide at a high ratio and prolongs the service of the catalyst.
