Abstract: Disclosed is a radome 1 for vehicle-mounted radar devices including a base body 2 having an electromagnetic wave permeable substrate 3 and a heater wire 41 laminated on an inner surface side of the substrate 3 and wired in a surface direction of the substrate 3, in which linear portions 411 of the heater wire 41 are arranged side by side at intervals in the surface direction of the substrate 3 in an electromagnetic wave irradiation region R of the substrate 3, and a surface occupancy ratio of the linear portions 411 of the heater wire 41 in the electromagnetic wave irradiation region R of the substrate 3 is set to 1% or more and 24% or less. It is possible to exhibit a practical snow-melting function as a radome for vehicle-mounted radar devices while suppressing attenuation of electromagnetic waves irradiated by a vehicle-mounted radar device within an allowable range.

Abstract: An increase control unit causes to apply a first voltage to a coil of a fuel injection valve to increase a driving current of the coil to a peak value. A holding control unit stops application of the first voltage, when the driving current increases to the peak value, and subsequently switches between a first holding control and a second holding control. The first holding control is to apply a second voltage lower than the first voltage to the coil based on at least one of the peak value, the second voltage, and a fuel pressure, to hold the driving current at a target current. The second holding control is to apply the first voltage to the coil to hold the driving current at the target current. The holding control unit performs one of the first holding control and the second holding control which is switched.

Abstract: A solid electrolyte comprises a microporous film having high crystallizability and excellent solvent resistance. The microporous film is controlled by a wet phase inversion method to a porosity of 50% or greater and a pore diameter of 0.02 &mgr;m to 1 &mgr;m inclusive. The solid electrolyte may be used to construct an electrochemical device, a lithium ion secondary battery and an electric double-layer capacitor.
