摘要:
A stable, high output is obtained with an anion exchange membrane-type fuel cell that generates electricity when air is supplied. An operating method for an anion exchange membrane-type fuel cell includes an anion exchange membrane electrode assembly for which an anode is joined to one surface of a anion exchange membrane and a cathode is joined to the other surface, and air is supplied to the cathode, wherein air with a reduced carbon dioxide concentration in the atmosphere is supplied to the cathode by a low carbon dioxide air supply system that supplies air with the reduced carbon dioxide concentration to the cathode.

The present invention provides a polarizable electrode for an electrical double layer capacitor which has good high-temperature storage characteristics and can prevent a decrease in electrostatic capacity and increase in internal resistance, and also provides an electrical double layer capacitor using the electrode. A polarizable electrode is formed by mixing Ketjen black, active charcoal and a polytetrafluoroethylene (PTFE) aqueous solution. An etched aluminum foil is used for the collector, and this etched aluminum foil is dipped in a phosphoric acid aqueous solution or an ammonium phosphate or other phosphate aqueous solution to thereby retain 15 to 115 mg/m2 of phosphorus on the surface of the etched aluminum foil. The electrostatic capacity per unit area on the surface of this etched aluminum foil is 50 to 350 μF/cm2.

摘要:
The present invention relates to an antenna device and enables the directivity of an antenna element to be changed without affecting the resonance frequency of the antenna element. The antenna device comprises a first grounded conductor, an antenna element mounted on the first grounded conductor via an insulator, a second grounded conductor disposed separate from the first grounded conductor, and a changing unit for changing directivity of the antenna element by adding the second grounded conductor to the first grounded conductor or canceling the addition thereof.
摘要:
Rays incident upon a plurality of detection plates arranged along a normal direction are detected. A distance between the ray and the ray source is estimated based on the number of counted rays detected by each detection plate, and each interval distance of the detection plates. Moreover, the direction of the source of the ray is estimated based on each image obtained from each detection plate.

摘要:
A seat rail extending rearwardly from a vehicle body frame to support a seat. The seat rail is formed of a left-and-right two-split cast product having a substantially flat upper surface and, at the same time, includes cross members. These cross members can be mounted later using bolts. The seat can be arranged above the seat rail and the cross members and, at the same time, a seat engaging member which engages the seat with the cross member can be formed on the cross member. The seat rail is constituted of the left and right seat rails which are divided with respect to a vehicle width center. This seat rail structure provides for simple manufacture and assembly.
摘要:
A screen for attachment to an front forked portion of a motorcycle has improved aerodynamic characteristics. An upper garnish is located on the forward side of the screen. The upper garnish extends substantially horizontally across the screen. An expanded portion protrudes forwardly and extends substantially across the entire length of the upper garnish. The expanded portion redirects any horizontal air current impacting thereagainst. The redirected air current influences the horizontal air currents impacting the screen by causing a turbulence area slightly in front of the screen. This turbulence acts to lessen the impact of the horizontal air currents against the screen, resulting in a decrease in an overall running resistance of the motorcycle.
摘要:
A structure for fixing an optical cable holding box to a printed circuit board whereby the fixed position of the optical cable holding box can be changed at will and occurrence of warping in the printed circuit board can be effectively prevented. A pair of extended first metal plates having a plurality of screw holes formed therein at equal spaces are fixed to the printed circuit board in the vicinity of its upper and lower edge portions along the upper and lower edges. A pair of vertically extended second metal plates having a plurality of screw holes formed therein at equal spaces are securely fixed to the pair of first metal plates with screws such that they are stretched between the first metal plates and spaced apart a predetermined distance from each other. Thereupon, the optical cable holding box is securely fixed with screws to the pair of second metal plates in a desired position.
