Abstract: The intention is to clarify characteristics of a cluster-free amorphous silicon film which is practically produceable without incorporation of large clusters having a size of 1 nm or more, and provide a method and an apparatus for producing the amorphous silicon film. In the cluster-free amorphous silicone (a-Si:H) film, an in-film Si—H2 bond density is 10?2 atomic % or less, and an in-film volume fraction of the large clusters is 10?1% or less. The a-Si:H film is produced by depositing, on a substrate, a deposition material in a plasma flow of any one of a silane gas, a disilane gas and a gas obtained by diluting a silane or disilane gas with one or a combination of two or more selected from the group consisting of hydrogen, Ar, He, Ne and Xe. The a-Si:H film has prominent characteristics, such that: a light-induced defect density is reduced from 2×1016 cm?3 or more in conventional a-Si:H films to substantially zero; a stabilized efficiency (%), i.e.

The pattern is set so that amplitudes of push-pull signals of the sub-beams are substantially cancelled in each of the light beams having different wavelengths. With this, it is possible to provide an optical pickup (i) having a plurality having different light sources in one package, (ii) capable of realizing low cost in the case in which the optical pickup carries out track detection using three beams with respect to any optical discs, such as DVDs and CDs, and (iii) capable of realizing simplifications of assembly adjustment and the pickup.

Abstract: An optical pickup includes a hologram element. The hologram element is provided with a hologram pattern including a splitting section for focus which splits light used for the detection of an FES and a splitting section for tracking which splits light used for the detection of a TES. The splitting section for tracking is formed in a region excluding a region interposed between a first virtual straight line and a second virtual straight line. The first virtual straight line is drawn on the hologram element in parallel to an X direction and passes through an optical axis of reflected light entering the hologram element in a state where the objective lens is in a neutral position, and the second virtual straight line is drawn in parallel to the first virtual straight line, while being spaced at a distance d from the first virtual straight line.

Abstract: An optical pickup device has a semiconductor laser emitting light which is in turn branched via a diffraction grating into at least three beams of light including a main beam and two sub beams which are in turn condensed via an objective lens on an optical disk at a guide groove and reflected by the optical disk to provide three reflections of light which are in turn received by detectors, each divided into two regions, respectively, to generate a tracking error signal. The diffraction grating is divided into three regions including a first region, a second region and a third region located intermediate therebetween, each having a periodical structure out of phase, the periodical structure having grating grooves in a direction determined depending on the phase of the second region to incline relative to a direction perpendicular to the guide groove of the optical disk.

Abstract: An optical pickup converts a laser beam from a semiconductor laser (1) into a parallel ray with a collimator lens (2), and divides it into a main beam (30), a sub-beam (+1st order component) (31), and a sub-beam (?1st order component) (32) with a gradient multiple-division type phase difference grating (3). After passing through a beam splitter (4), an objective lens (5) condenses the light beams on a track (61) of an optical disc (6), and the reflected light that has passed through the objective lens 5 is reflected at the beam splitter (4) and is guided into optical detectors (8A, 8B, and 8C) by a condensing lens (7). Accordingly, in a tracking error signal detecting method using the push-pull signals of the main beam and sub-beams, an offset produced by an objective lens shift or a disc tilt can be cancelled at low cost without lowering the efficiency of using light.

Abstract: Systems and methods for modes of operation for processing data are disclosed. While executing a program in one mode the hazard checking logic present in the microprocessor system may be utilized to check or ameliorate the hazards caused by the execution of this program. However, when a program does not need this hazard checking, the microprocessor may execute this program in a mode where some portion of the hazard checking logic of the microprocessor may not be utilized in conjunction with the execution of this program. This allows the higher speed execution of these types of programs by eliminating checking for dependencies, the detection of false load/store dependencies, the insertion of unnecessary stalls into the execution pipeline of the microprocessor or other hardware operations. Furthermore, by reducing the use of hazard detection logic a decrease in power consumption may also be effectuated.
