    摘要: A process for the production of a lanthanum chromite film, including the steps of preparing a plasma spray powder by mixing 1-15 parts by weight of powdery chromium oxide powder to 100 parts by weight of powdery lanthanum chromite, this lanthanum chromite having a composition ratio of A sites to B-sites being in a range of 1:1 to 1:0.9, forming a plasma sprayed film by plasma spraying the plasma spray powder onto a substrate, and forming the lanthanum chromite film by heat treating the resulting plasma sprayed film. The plasma spray powder may be produced by preparing a mixed powder by adding 1-15 parts by weight of powdery chromium oxide to 100 parts by weight of a synthesis powder capable of producing the lanthanum chromite film by heat treatment, the synthesis powder containing at least chromium oxide and lanthanum chromite and the lanthanum chromite film having a composition ratio of A-sites to B-sites being in a range of 1:1 to 1:0.9, obtaining a synthesized product by heating the mixed powder, and granulating the synthesized product.

    摘要: A saddle seat type fuel-cell electric vehicle includes a body frame having a pair of right and left main frames connected at their front ends to a head pipe and extending downward therefrom and a pair of right and left under frames connected at their front ends to the head pipe and extending downward therefrom along the right and left main frames on the lower side thereof. A pair of hydrogen cylinders extend substantially vertically along the body frame between the front side of the head pipe and the front side of the front end portion of the footrest so as to interpose the body frame in the lateral direction of the vehicle. A fuel supply unit is provided in a space surrounded by the main frames and the under frames with the hydrogen cylinders being surrounded by a guard pipe connected to the main frames.
