摘要： A fuel hose comprises a single layered or multi-layered tubular rubber body and a thin film resin layer formed on the inner circumferential surface of the innermost layer of the tubular rubber body. The resin layer is formed of a resin such that an amount of permeation of 10% ethanol-mixed gasoline is 2 mg/cm2/day (at 60° C.) or less when the thickness of the resin layer is 0.1 mm. A preferred example of such a resin is EVOH with an ethylene content of from 35 to 50 mol % or polybutylene aromatic ester. The fuel hose has necessary flexibility and shows excellent impermeability even to an alcohol-mixed gasoline.

摘要： A connector mounting structure has a fluid line component with a connecting hole, a connector mounted to the fluid line component and a positioning mechanism. The connector includes a connecting portion inserted in the connecting hole. The positioning mechanism is arranged between the connecting portion and the fluid line component. The positioning mechanism includes a first engaging portion in the connecting portion and a second engaging portion in the fluid line component. The first and the second engaging portions engage with one another so as to position the connecting portion relative to the connecting hole in the circumferential direction. The positioning mechanism allows to position the connecting portion relative to the connecting hole selectively at any one of a number of the mounting angular positions. The second engaging portion may be formed below the rim portion of an opening of the connecting hole.

摘要： A jitter counter according to the present invention is connected to a PLL circuit for generating a clock signal, which is necessary for signal processing, from a binary signal, and counts jitters of the binary signal. The jitter counter comprises: a determination signal generation circuit which uses an output signal from a VCO constituting the PLL circuit and the like to generate a determination signal that has a given pulse width having the phase center at the position of a pulse edge of the clock signal; a phase determination circuit which at every time when logic inversion of the binary signal occurs, determines whether or not the inversion position is present in a determination section given by the pulse width of the determination signal based on an output signal from a phase comparator constituting the PLL circuit and on the determination signal; a phase counter which counts the number of times that inversion positions of the binary signal are not present in the determination section (or times that inversion positions of the binary signal are present in the determination section) based on an output signal from the phase determination circuit, wherein a count value of the phase counter is output as a jitter count value.
