摘要: An optical-pickup apparatus includes: a single-wavelength-laser diode to emit a first-laser beam; a two-wavelength-laser diode to emit second- and third-laser beams; an objective lens; a photodetector to be irradiated with first- to third-reflected-light beams of the first- to third-laser beams reflected from the signal-recording layers of first- to third-optical discs; an aberration-correcting plate to guide the second- and third-laser beams toward the lens, and correct astigmatism of the reflected-light beams, and guide the astigmatism-corrected-reflected-light beams toward the photodetector; a semitransparent mirror to guide, toward the lens, the first-laser beam and the second- and third-laser beams having been guided by the aberration-correcting plate, and guide the reflected-light beams toward the aberration-correcting plate; a quarter-wave plate to convert the first- to third-laser beams from linearly-polarized light into circularly-polarized light, and convert the reflected-light beams from circularly-polarized light into linearly-polarized light; and a divergent lens to correct aberration caused by the mirror.

摘要: A fluid-filled vibration damping device including: a pressure-receiving chamber and an equilibrium chamber disposed on either side of a partition plate, while being connected through a first orifice passage; a moveable film arranged to either a pressure-receiving chamber side or an equilibrium chamber side of the partition plate while being spaced away therefrom to define therebetween an intermediate chamber; a second orifice passage connecting the intermediate chamber and one of the pressure-receiving and the equilibrium chambers while being tuned to higher frequency than the first orifice passage; and a flow straightening plate arranged in opposition to the moveable film at least at one of the intermediate chamber side and an opposite side thereof, the flow straightening plate having a plurality of flow straightening apertures opening towards the moveable film and furnished with a flow limiting member.

摘要: An internal combustion engine for a vehicle comprises a pair of intake collectors (3A, 3B) and a communicating pipe (13) connecting the pair of intake collectors (3A, 3B). A negative pressure supply port (15) supplying intake negative pressure of the internal combustion engine to a brake booster is provided at an end of the communicating pipe (13). By providing an air amount deviation compensating arrangement which compensates for a deviation in the amounts of air flowing into the pair of intake collectors (3A, 3B) from the brake booster when braking of the vehicle is released, the amounts of air supplied to the internal combustion engine from the pair of the intake collectors (3A, 3B) are equalized.
