Abstract: An electrode including LaNixMyO3-z on a substrate, and having an initial double layer capacitance of more than 0.6 F/cm2, where x+y is 0.8 or more and 1.2 or less, y is 0.001 or more and 0.6 or less, z is ?0.5 or more and 0.5 or less, and M includes at least one of Nb, Ta, Sb, Ti, Mn, or Zr.

Abstract: A radar device includes: a receiving circuit mixing a transmission signal with reception signals; a first detecting unit detecting information on the rotation angle of a vehicle equipped with the radar device, on the basis of an output signal of a yaw rate sensor; a second detecting unit detecting the internal temperature of the radar device on the basis of an output signal from a temperature sensor; a power supply circuit supplying electric power to the receiving circuit and the yaw rate sensor; and a control unit repeatedly setting power supply periods and power supply stop periods of the receiving circuit, in which, in a case where the internal temperature is equal to or lower than a predetermined temperature, the control unit performs control such that the power supply stop periods of the receiving circuit become shorter than those in a case where the internal temperature exceeds the predetermined temperature.

Abstract: An object of the present invention is to provide a sol of an inorganic porous substance having a small particle diameter and a uniform pore diameter, and a synthetic method thereof, and uses using the same, in particular, an ink-jet recording medium excellent in ink absorbing property, transparency, water resistance and light resistance, and a coating liquid for an ink-jet recording medium. The invention relates to a sol containing an inorganic porous substance, the inorganic porous substance having an average particle diameter, measured by the dynamic light scattering method, of 10 nm to 400 nm, an average aspect ratio of its primary particles of 2 or more and meso-pores extending in the longitudinal direction, and suffering from substantially no secondary aggregation.
