Abstract: The adapter includes a housing and a filling nozzle provided in communication with a containing portion in the housing and coming into contact with an end surface of the injection device, in which the injection port of the injection nozzle is formed, when the housing is attached to the injection device. An open end of the filling nozzle is set to be smaller than an inner diameter of the containing portion and larger than the injection port. Of an internal space of the housing from a partial region of the containing portion to the open end, at least a predetermined space being continuous and including the partial region is formed in a manner where an inner diameter of the predetermined space decreases toward a side of the open end. According to this configuration, the injection fluid can be suitably transferred from the outside to a needleless injector.

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.
