摘要： An optical path coupling member aligns an optical axis directed to a light condensing member of the first wavelength light having a shortest wavelength with that of the third wavelength light having a longest wavelength. A diffraction element condenses +2nd order diffracted light of the first wavelength light and +1st order diffracted light of the second wavelength light and third wavelength light into a first photodetector, the −2nd order diffracted light of the first wavelength light and −1st order diffracted light of the third wavelength light into a second photodetector, and −1st order diffracted light of the remaining second wavelength light into a photodetector, using ±2nd order diffracted light of the first wavelength light and ±1st order diffracted light of the second wavelength light and third wavelength light as signal light from an optical information recording medium. Consequently, the overall size of the optical pickup apparatus is reduced.

摘要： An optical pickup device includes a diffraction grating 12 for separating an emitted light beam into at least three light beams. The diffraction grating 12 is divided into three regions by dividing lines D1 and D2 extending in a first direction parallel to a tangent line of a track of an optical information recording medium. A second region 12B is divided into four sub-blocks by a dividing line D3 extending in the first direction and a dividing line D4 extending in a second direction that crosses the first direction. The sub-blocks located diagonally opposite to each other have a same phase, and the sub-blocks located adjacent to each other have a phase difference of approximately 180 degrees. The first region 12A has a phase difference of approximately 90 degrees from each sub-block of the second region 12B, and the first region 12A has a phase difference of approximately 180 degrees from the third region 12C.

摘要： A vehicle engine start control device in a vehicle includes a direct injection engine directly injecting fuel into a cylinder as a drive power source for running. The vehicle engine start control device is configured to start rotation of the direct injection engine when the direct injection engine is started from a stop state of the direct injection engine in which a first cylinder of a plurality of cylinders is in an expansion stroke while a second cylinder next to the first cylinder in an ignition order is located at a top dead center. Further, the device directly injects fuel into the second cylinder and ignites the fuel while a piston of the second cylinder is moving away from the top dead center toward a bottom dead center in a first expansion stroke in the second cylinder after the start of the rotation.
