Abstract: Provided is a hollow organ model unit. The hollow organ model unit includes a base that includes a recessed part, a hollow organ model that is placed in the recessed part, a filler that is filled in the recessed part, and a sensor that performs a measurement on the hollow organ model.

Abstract: A semiconductor device includes an interlayer insulating film; a wiring formed on the interlayer insulating film so as to protrude there from and made of a material having copper as a main component, the wiring having a thickness direction and having a cross sectional shape of an inverted trapezoid that becomes wider in width with distance away from the interlayer insulating film; and a passivation film formed so as to cover the wiring. The passivation film is made of a laminated film in which a first nitride film, an intermediate film, and a second nitride film are laminated in that order from the wiring side. The intermediate film is made of an insulating material differing from those of the first and second nitride films, and has a tapered portion having a cross sectional shape of a trapezoid that becomes narrower in width with distance away from the interlayer insulating film.

The passivation film is made of a laminated film in which a first nitride film, an intermediate film, and a second nitride film are laminated in that order from the wiring side. The intermediate film is made of an insulating material (for example, an oxide) differing from those of the first and second nitride films.

Abstract: An FRP drive shaft wherein the shaft body and the flanges are formed in a body and a method of manufacturing the same are disclosed. The shaft body is formed by winding a resin impregnated fiber on a mandrel having pins on its circumferential surface while hooking the fiber on the pins. The fiber is then circumferentially wound to form a hoop-like reinforcing band near each end of the shaft body. After the pins and end parts of the mandrel are removed, each end portion of the shaft body is expanded by a pressing mold to form a flange. After hot setting, the remaining part of the mandrel is removed.

Abstract: A magnesium aluminometasilicate coated composite powder which comprises magnesium aluminometasilicate, or magnesium aluminometasilicate and at least one other powder coated on a surface of a core powder and which is usable in, for example, a skin treatment agent, decodorant, and oral composition.

Abstract: A column packing material comprising a porous support coated with a silicone polymer having an Si--R bond, wherein R is a hydrocarbon group having 1 to 18 carbon atoms, and an Si--R' bond, wherein R' is a hydrophilic group having one or more of polyoxyalkylene group or hydroxyl group at the terminal end, of which column packing material is produced by:modifying a porous support by bonding hydrocarbon groups to the porous support;eliminating a part of the hydrocarbon groups from the modified porous support; andmodifying the porous support by bonding hydrophilic groups thereto.

Abstract: A composite powder wherein an organic or inorganic core powder is substantially completely covered with one or more types of organic, inorganic, or metallic powders having an average particle size one-fifth or less of the average particle size of the above core powder by means of mixing and compression. The composite powder may be manufactured by mixing and compressing the above core powder and coating powder using a ball mill or other mixer charged with a ball shaped mixing medium of an average diameter of 5 mm or less. This composite powder may be used in, for example, skin treatment agent, makeup type cosmetics, sunburn preventing cosmetics, deodorants.

Abstract: A quadrangular combustion cavity V in the crown of a diesel engine piston is offset from the center thereof, and the position of the fuel injector nozzle is also offset relative to the center of the cavity to accomodate enlarged intake and exhaust valves. The rotational orientation of the nozzle and cavity are geometrically determined such that:A. the fuel distances J.sub.1, J.sub.2 and J.sub.3, J.sub.4 are equal,B. the angles between a line A connecting the geometric center C.sub.1 of the cavity and the center C.sub.2 of the nozzle, and fuel jet directions J.sub.1 and J.sub.2 are equal, as are the angles between line A and fuel jet directions J.sub.3 and J.sub.4, andC. the difference between the maximum jet distance J.sub.1 and the minimum jet distance J.sub.3 is minimizedThe distances from the four fuel impingement points Z.sub.1 - Z.sub.4 on the side walls of the cavity to the respective corners of the cavity are also equal.
