  • Patent number: 7420310
    Abstract: Of two bearings supporting a rotor of a circuit-integrated type core-equipped brushless motor, a part of an outer periphery of the bearing, which is disposed at a position near a stator core, is allowed to directly abut on an inner periphery of a hole formed in a center of the stator core, and therefore, reduction in thickness, reduction in diameter, space-saving and enhancement in output power can be realized. The stator core is fixed to the casing by causing projected parts provided at the housing to bite into second notched parts formed inside first notched parts formed at the stator core and crimping them, whereby the problem of a decrease in a winding space accompanying reduction in a diameter of the stator core is solved, and reduction in thickness, reduction in diameter, space-saving and enhancement in output power are achieved.

  • Patent number: 6910008
    Abstract: A random code vector reading section and a random codebook of a conventional CELP type speech coder/decoder are respectively replaced with an oscillator for outputting different vector streams in accordance with values of input seeds, and a seed storage section for storing a plurality of seeds. This makes it unnecessary to store fixed vectors as they are in a fixed codebook (ROM), thereby considerably reducing the memory capacity.

  • Patent number: 6895172
    Abstract: In a video signal reproducing apparatus, the changing time of a sub-video signal is adjusted, by a time-adjusting circuit, so as to be synchronized with the changing of a frame of a main video signal from the output of an interlace-scan-video-signal converter. And the sub-signal is added to the output of an interlace-scan converter by an adder. The output of the adder is converted into a progressive-scan video signal in synchronism with the boundary of frames of main video signal by the progressive-scan video signal converter. In the reproducing apparatus, even in the case that the sub-video signal is recorded without synchronism with the frames of the main video signal, an irregular frame is not generated even when the sub-video changes. And a single field of the sub-video does not leave or is not visible.

  • Patent number: 6886176
    Abstract: An optical disk drive includes a turntable, a first motor for turntable drive, an optical pickup and a drive mechanism arranged on a drive base and a separate traverse base that floats on the drive base. A loading drive mechanism drives a disk loading mechanism. A second motor can be driven in forward and reverse directions to supply drive power to the loading drive mechanism and a pickup drive mechanism. A drive power transfer path switching mechanism is used to switch the path through which drive power from the second motor is transferred to supply power to the loading drive mechanism and pickup drive mechanism. By continuously driving the second motor in one direction, then moving the optical pickup, raising or lowering the turntable, and transporting a disk can be accomplished in this sequence substantially continuously. By reversing the direction of motor drive, these operations can be accomplished substantially continuously in reverse direction in reverse sequence.

  • Patent number: 6433305
    Abstract: A method of laser machining using an ultra-fast pulse laser is presented. According to the present invention a plurality of holes with a pitch less than the wavelength of the laser are drilled into a material sample. Reliable and reproducible hole drilling is accomplished through an exemplary drilling sequence which applies a number of pulses at a first pulse energy to the surface spaced to avoid laser hardening of the surface for adjacent holes of a first set of holes. Next, the number of pulses is increased or the energy of the laser beam is increased to drill holes that are interstitial to the first set of holes. The exemplary laser machining process may used to produce both one-dimensional and two-dimensional photonic crystals, among other applications.
