摘要： In an optical recording method and apparatus for an optical storage medium, a recording pulse pattern having a sequence of multiple pulses is used to record one of plural kinds of marks with different lengths on the storage medium through a variable-linear-velocity recording process or a constant-angular-velocity recording process. Two or more discrete write powers are individually allocated to the respective pulses of the recording pulse pattern. Each of the write powers, allocated to the respective pulses of the recording pulse pattern, is linearly varied in proportion with a change of one of the recording linear velocity and a recording position of the storage medium. The resulting recording pulse pattern is supplied to a pickup, and the pickup emits a light beam to the storage medium in accordance with the recording pulse pattern having the linearly varied write powers allocated to the respective pulses, so that one of the plural kinds of marks is recorded on the storage medium.

摘要： A differential mechanism comprises a differential case assembly having a casing body connected to a source of drive force and a cap member coupled with the casing body to cover one opened end of the casing body, a plurality of input blocks housed in the case assembly and being movable circumferentially of the case assembly in correspondence with rotation of the casing body, and a pair of output cam members for clamping the input blocks relatively slidably and being independently rotatable owing to a frictional force produced with respect to each of the input blocks to thereby initiate a differential motion on an output side of the differential mechanism. The input blocks are provided in at least two different types and having projected portions. The projected portions of the input blocks of one type have a first upper end width while the projected portions of the input blocks of another type have a second upper end width different from the first upper end width. The casing body has first and second axial grooves provided on an inner peripheral surface thereof such that they extend axially of the differential mechanism. The axial grooves are shaped complementary to the projected portions of the input blocks for meshing engagement therewith. This arrangement prevents misassembling of the differential mechanism.

摘要： A pulsed electromagnetic-wave generator includes an excitation light source, a laser resonator, a pulse generating unit, and a wavelength converting unit. Excitation light from the excitation light source enters the laser resonator. The pulse generating unit is configured to generate a pulsed light group including at least two or more pulses with different frequencies (ω) and different oscillation timings (t) in one excitation process of the excitation light source, an oscillation frequency difference (Δω) between the pulses in the pulsed light group being an integral multiple of a Free Spectral Range (FSR) of the laser resonator. The pulsed light group enters the wavelength converting unit. The wavelength converting unit is configured to generate a pulsed electromagnetic wave in which a wavelength of each pulse in the pulsed light group is converted.

摘要： A transmission for an internal combustion engine that allows a fit length between a dog and a dog hole to be made longer and gear splines to be made longer, without having to increase an axial length of the transmission. A transmission selectively performs gearshifting by using a shift fork to slidingly move a shift gear of the transmission axially and by using a dog clutch to engage the shift gear with, or disengage the shift gear from, an adjacent gear. When the shift gear slidingly moves, a gear-side spline portion of the shift gear slidingly moves over a shaft-side spline portion.

摘要： A wavelength conversion device enabling the stable output of high-power harmonic light is disclosed. The wavelength conversion device includes MgO:LiNbO3 (PPMgLN) having a periodic polarization reversed structure, and the +Z and −Z surfaces of the PPMgLN are covered with thin chrome (Cr) film. In the PPMgLN, the incident surface and output surface are disposed on the −X side and +X side, respectively, in the longitudinal direction. Because of this structure, even when a high-power laser fundamental wave is incident, the PPMgLN can avoid destruction and damage due to the electric field, thereby enabling the stable output of high-power harmonic.
