  • Patent number: 8123829
    Abstract: A bearing holder (66) having a bearing (67) rotatably supporting a crankshaft (14) is fixed so as to face an opening (11k) of the engine case (11). A gas-liquid separation chamber (83) is formed between a cover member (68) covering the opening (11k) and the bearing holder (66). Therefore, by utilizing the bearing holder (66) as a part of the wall surface of the gas-liquid separation chamber (83), the gas-liquid separation chamber (83) can be partitioned without increasing the number of components and without forming a special wall surface in the engine case (11). Thus, it is possible to reduce the size and weight of the engine case (11), and reduce the cost by simplifying the shape thereof and reducing the number of components. Also, a labyrinth 82 is formed by ribs (66d, 66e, 68a, 68d) projecting from the bearing holder (66) and the cover member (68), and therefore gas-liquid separation can be effectively performed by the labyrinth (82).

  • Patent number: 7738337
    Abstract: It is an object of certain inventive aspects to provide a recording condition closer to an optimum even for a medium unknown to a drive, and more particularly, to provide means for obtaining a preferable recording condition even for a high-speed recording in which conducting a test recording is difficult. In order to accomplish the object, a power and a phase of a recording pulse are simultaneously corrected at predetermined timing, depending on a recording speed or a recording position such as an inner or outer circumference. For instance, a phase shift ?Phase generated due to a continuing recording from an inner circumference to an outer circumference at ×2 speed is corrected simultaneously with a correction of a power shift at the timing when a recording speed is changed from ×2 to ×4. For the other recording speed, in the same manner as above, a power and a phase shift are simultaneously corrected at every time when a recording speed is changed.

  • Patent number: 7693015
    Abstract: It is an object of the present invention to improve a margin to meet good recording quality by conducting a realtime correction of a recording condition of a medium with different recording characteristics for inner and outer circumferences. To accomplish the object, control factors for power and a pulse width are independently detected and corrected using an mT pulse having a length of m?T as a pulse for power control and an nT pulse having a length of n?T as a pulse for pulse width control; more specifically, power correction for mT pulse and pulse width correction for nT pulse are conducted in realtime, wherein a recording pulse stream including the mT pulse and nT pulse is irradiated onto a medium by a recording laser beam as well as pits and spaces formed by irradiation of the recording pulse stream are reproduced by a reproducing laser beam to detect the effects of power and pulse width variations independently.

  • Patent number: 7633844
    Abstract: An optical information recording apparatus corrects a recording condition for an optical medium having a difference in recording property between the inner and outer peripheries in real time. The optical information recording apparatus obtains an RF signal by using a playback sub beam and retrieves a portion of the RF signal corresponding to a constant output zone of a recording pulse using a gate signal. An average value of the retrieved signal is computed so as to set a reference position in real time. A difference between the top peak value of the retrieved signal and the average value and a difference between the bottom peak value of the retrieved signal and the average value are computed so as to obtain a ? value in real time from the on-and-off RF signal affected by the recording pulse that turns on and off.
