摘要： In coupling a part or component of synthetic resin mounted on a vehicle and a threaded member capable of detachably engaging with the part, the part is provided with a retaining portion for retaining at least a portion of the threaded member against rotation relative to each other, and a claw construction means capable of disengageably engaging with the threaded member so as to inhibit the separation of the threaded member from the retaining portion. With this coupling structure, the operation of molding a part of synthetic resin for a vehicle having a threaded member integrally incorporated therein can be carried out easily and a labor-saving is achieved in the operation. Further, the recycling of parts defectively formed or the like can be promoted.

摘要： A pump that includes a pump body 10 which sucks in air from an inlet 7 and discharges the air; a hydraulic pump which pressure-feeds a lubricating oil to the pump body 10 in accordance with the driving of the pump body 10; a non-return valve 70 which is disposed in a valve accommodation portion 6 between the inlet 7 and the pump body 10 to open and close the valve accommodation portion 6; an air introduction path 19 which introduces air into a cylinder 74 of the non-return valve 70; and an air introduction valve 60 which opens the air introduction path 19 when the hydraulic pump is not operating. When the pump body 10 is stopped, the non-return valve 70 closes the inlet 7 in response to a difference in pressure between the pressure of the valve accommodation portion 6 reduced to a value equal to or less than atmospheric pressure by the operation of the pump body 10, and the pressure of the air introduced into the cylinder 74 by the opening of the air introduction valve 60 owing to the stoppage of the hydraulic pump associated with the stoppage of the pump body 10.

摘要： An optical system for an optical head of an optical disc drive is capable of using first and second discs, protective layer of the second disc being thicker than that of the first disc, a data density of the second disc being lower than that of the first disc. A light source selectively emits first and second laser beams having first and second wavelengths, respectively. An objective lens converges the first and second beams on the first and second discs, respectively. The second beam is incident on the objective lens as diverging light, and the first beam is incident on the objective lens as a beam of which degree of divergence is smaller. A diffraction lens structure is formed in the high NA exclusive area, which compensates for aberrations of a portion of the first laser beam, and causes aberrations to a portion of the second laser beam passed therethrough.

摘要： Disclosed is an objective lens of an optical pick-up that converges light beams of two different wavelengths onto recording layers of optical discs of two different recording densities, respectively. The objective lens includes a refractive lens whose one surface is divided into a common area through which a light beam of a low NA, which is necessary and sufficient for an optical disc having low recording density, passes and a high NA exclusive area through which a light beam of a high NA, which is necessary only for an optical disc having high recording density, passes. A diffractive lens structure is formed in both the areas. The diffractive lens structure in the common area maximizes the diffraction efficiency of the first order and that in the high NA exclusive area maximizes the diffraction efficiency of the second or third order at the wavelength corresponding to the optical disc having high recording density.

摘要： An objective lens for an optical head converges a first laser beam having a relatively short wavelength and a second laser beam having a relatively long wavelength on first optical disc (DVD) and a second optical disc (CD), respectively. A protective layer of the first disc is thinner than a protective layer of the second optical disc. The objective lens is compensated for astigmatism with respect to the first beam, which is incident on the objective lens as an off-axis beam at a predetermined incident angle, by providing on-axis astigmatism corresponding to wave front aberration greater than or equal to 0.01&lgr; (rms), and the objective lens is configured such that the coma is compensated better in a case where the first laser beam is converged on the first optical disc than in a case where the second laser beam is converged on the second optical disc.

摘要： An optical system of an optical pick-up includes a light source portion that selectively emits a first laser beam (shorter wavelength) and a second laser beam (longer wavelength), and an objective lens for converging the first laser beam onto a first optical disc and for converging the second laser beam onto a second optical disc. The second optical disc has lower recording density and a thicker cover layer than the first optical disc. The divergence of the second laser beam incident on the objective lens is larger than that of the first laser beam, correcting one part of spherical aberration caused by a difference in thickness of the cover layer. A diffractive lens structure is formed on a surface of the refractive lens so that the residual part of the spherical aberration is corrected by switching the wavelength of the laser beam.
