The invention provides an SHG laser light source whose optical output can be modulated using a simple mechanism without having to equip the light source with an external modulator, and a method of modulation for use with the SHG laser light source, wherein the SHG laser light source comprises a laser diode for outputting a fundamental wave of light, a drive circuit for simultaneously modulating one or more electric currents or voltages supplied to the laser diode to modulate the fundamental wave outputted by the laser diode, and an SHG device which receives the modulated or unmodulated fundamental wave, converts the wavelength thereof, and outputs a second harmonic wave which is intensity modulated.
摘要:
A tank joint part has a welding member welded to the outer surface of a fuel tank and a main body formed of a material of low fuel permeability and welded or otherwise joined to the welding member. The welding member is formed of modified polyethylene, which is easily weldable or otherwise joinable to the outer surface of the fuel tank and the main body, and in which very fine particles of a layered mineral are easily dispersible. The mineral is dispersed in layers oriented substantially at right angles to the direction of any possible permeation from the tank joint part. The tank joint part ensures a low fuel permeability and a high bonding strength.
摘要:
A fuel transporting tube including an inner layer which contacts a fuel being transported and which is formed of a polybutylene naphthalate resin, an outer layer which is provided radially outwardly of the inner layer and which is formed of a polyamide resin or a polyolefin resin, and an intermediate layer which is provided between the inner layer and the outer layer and which is formed of a resin to adhere the inner and outer layers to each other.
摘要:
A fuel hose comprising a rubber layer and a fluororesin layer formed on the inner surface of the rubber layer, in which the adhesion to the fluororesin layer is improved by blending from 2 to 15 phr of a phenol-type resin with the rubber forming the rubber layer. Phenol resins of a specific polymeric structure are particularly preferred as the phenol-type resins. A fluororesin layer formed by melting a fluororesin and allowing it to adhere to the inner surface of the rubber layer by powder coating is particularly preferred. The provision of the fluororesin layer on the inner surface of the rubber layer enables simple and effective adhesion of the thinned fluororesin layer to the rubber layer.
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.
