Abstract:
A titanium alloy including by mass %, a platinum group metal: 0.01 to 0.15% and a rare earth metal: 0.001 to 0.10%, with the balance being Ti and impurities. The titanium alloy preferably includes as a partial replacement for Ti, Co: 0.05 to 1.00% by mass, and the content of the platinum group metal is preferably in the range of 0.01 to 0.05% by mass. Furthermore, it is preferred that the platinum group metal be Pd and the rare earth metal be Y. Consequently, it is possible to provide a titanium alloy having corrosion resistance comparable to or better than that of the conventional art as well as good workability while offering an economic advantage with a lower content of platinum group metal or an advantage of less likelihood of corrosion growth originating at defects such as flaws that occurred in the surface.
Abstract:
A stainless steel member for a separator of a solid polymer fuel cell has excellent cell properties with little deterioration in performance over long periods of operation without worsening of the corrosion resistance of a stainless steel separator. The stainless steel member has a stainless steel base metal, and a passive film and electrically conductive precipitates both provided on a surface of the stainless steel base metal. The electrically conductive precipitate penetrates the passive film and includes a substance originating from the stainless steel base metal. An electrically conductive layer comprising a nonmetallic electrically conductive substance is preferably provided on the surface of the passive film, and the electrically conductive layer is preferably electrically connected to the stainless steel base member through the electrically conductive precipitates.
Abstract:
A titanium material for a polymer electrolyte fuel cell separator consists of, by mass %, a platinum group metal: 0.005% to 0.15% and a rare earth metal: 0.002% to 0.10%, with the balance being Ti and impurities. The titanium material of the present invention is provided with a film formed of a titanium oxide and a platinum group metal on the surface thereof. It is preferred that the film has a thickness of 50 nm or less, and that the concentration of the platinum group metal on the surface of the film is 1.5% by mass or more. With the thus formed film, the titanium material of the present invention is capable of achieving a reduction in initial contact resistance and ensuring good corrosion resistance. In the titanium material of the present invention, the rare earth metal is preferably Y, and the platinum group metal is preferably Pd.
Abstract:
An illumination device for a vehicle includes a light source and an inside handle well. The inside handle well has a lower wall, an upper wall, and an opening. The light source is arranged under the lower wall. The lower wall has a light exit portion configured such that light emitted from the light source exits therethrough and travels to an inside of the inside handle well. The upper wall has a light reflecting portion configured to reflect light exiting through the light exit portion and traveling upward in the inside handle well toward the inside handle. The opening is formed on the inner side of the interior of the vehicle.
Abstract:
An engine (1) has first and second cylinder groups (1a) and (1b). The first cylinder group (1a) is connected to a three way (TW) catalyst (8a). The second group (1b) and the TW catalyst (8a) are connected, via an interconnecting duct (13) to an NH.sub.3 adsorbing and oxidizing (NH.sub.3 -AO) catalyst (14a). The first group (1a) performs the rich operation, and the second group (1b) performs the lean operation. In the TW catalyst (8a), NO.sub.x exhausted from the first group (1a) is converted to NH.sub.3, and the NH.sub.3 reduces the NO.sub.x exhausted from the second group (1b) in the NH.sub.3 -AO catalyst (14a). A NO.sub.x occluding and reducing (NO.sub.x -OR) catalyst (11a) is arranged in the exhaust passage between the second group (1b) and the interconnecting duct (13), to thereby suppress the NO.sub.x amount flowing into the NH.sub.3 -AO catalyst (14a).
Abstract:
In a translation apparatus, a desire phrase is input via a tablet by selecting an appropriate item from a menu or inputting of a desire sentence in a first language. A desire analyzer analyzes the desire phrase and, if a conversational situation cannot be specified, presents a query for narrowing the desire content. When the conversational situation is specified, the desire analyzer presents a query for further narrowing the desire content, thereby determining the phrase to be translated. An optimum conversational sentence selector selects a conversational sentence in a second language which expresses the determined desire content from a conversational sentence storage, and a display section displays the selected conversational sentence.
Abstract:
A recording device for recording information upon optically modulated overwritable magneto-optical recording medium including four magnetic layers first records DC "1" and then a test signal at high and low recording laser power levels upon a test track of the recording medium. The high and low recording laser power levels are successively modified to scan a two-dimensional region of the high and low recording laser power levels, and the optimal high and low recording laser power levels are determined on the basis of the reproduction signal levels corresponding to respective combination of high and low recording laser power levers. The reproduction signal levels are represented upon the .alpha.-K plane which is divided into six characteristic regions, The optimal combination of high and low recording laser power levels is determined as a representative point within the region of correct reproduction with a predetermined allowance.
Abstract:
The clad material comprises outer layers each consisting of Ni or Ni alloy and a base layer consisting of Cu or Cu alloy, and is characterized in that peeling-off at a clad boundary is not recognized in cross section observation made after the clad material has been subjected to a 90° reverse bend test ten times, and the number of reverse bend cycles before rupture is 17 cycles or more. The clad material has with both of excellent corrosion resistance against electrolytic solution and high electric conductivity.
