A titanium alloy contains vanadium, from 10 to 20% by weight; aluminum, from 0.2 to 10% by weight; and a balance essentially titanium, and the alloy has a microstructure including a martensite phase. Alternatively, the titanium alloy contains vanadium, from 10 to 20% by weight; aluminum, from 0.2 to 10% by weight; and a balance essentially titanium, and the alloy has a microstructure including a β phase capable of transforming into a martensite phase by cold working or cooling under a room temperature.

A method of producing a metal gasket having at least a cooling water opening comprises steps of coating a surface treatment agent on an outer surface of the metal gasket, covering by a masking jig the outer surface of the metal gasket except a region surrounding the cooling water opening, and removing the surface treatment agent in the region by jetting superhigh pressure water at the region.
摘要:
A metal gasket for an internal combustion engine has cylinder openings and a cooling water openings and is coated on its outer surface with a surface treatment agent. The surface treatment agent in a region of the metal gasket surrounding the cooling water openings has been removed. A method of producing a metal gasket having at least a cooling water opening comprises steps of coating a surface treatment agent on an outer surface of the metal gasket, covering by a masking jig the outer surface of the metal gasket except a region surrounding the cooling water opening, and removing the surface treatment agent in the region by jetting superhigh pressure water at the region.
摘要:
An electrical connector (1) includes an insulative housing (2) for receiving a sheet-like connection member, a plurality of electrical contacts (4) received in the housing, and an operation member (3) mounted onto the housing. The housing has a lower wall (24) and an upper wall (22) opposite to the lower wall. The upper wall forms a plurality of second ribs on a bottom thereof. Each second rib forms a curved end (226) exposed outwardly from an edge (222) of the upper wall. The operation member forms an elongate pressing portion (324) at a bottom thereof, and a channel (322) defined in a main face thereof opposite from the pressing portion. The operation member is rotatable from an open position to a closed position, with the channel pivoting about the curved ends of the first ribs of the housing, thereby pressing the connection member upon the contact arms of the contacts.
摘要:
An electrode assembly for display apparatus is disclosed. A plurality of electrodes of different rigidities are provided between a cathode and a fluorescent material through coupling spacers. Plural kinds of coupling spacers are prepared in each of which the materials of a substrate metal, an insulating layer and a glass frit are different from each other and the proportional thicknesses of these components are varied to the extent that the intervals between the electrodes of different rigidities are not changed are prepared. An electrode block is completed by arranging the electrodes and the spacers such as to cancel the rotating moment around the neutral axis of the electrode block and joining them by means of calcination. The assembling accuracy of the electrode block is heightened very advantageously for positional accuracy with respect to the fluorescent screen.
摘要:
A magnetic alloy which contains not less than 0.03 weight percent but not more than 5.0 weight percent of P, not less than 0.01 weight percent but not more than 5.0 weight percent of at least one element of Ti, Nb, and Zr, not less than 2.5 weight percent but not more than 10 weight percent Si and the remaining part consisting mainly of Fe is disclosed. In the alloy, P is segregated on the grain boundaries thereof with a specified amount which results in a superior magnetic characteristics and workability represented by the fact that the alloy can be rolled.
