  • Publication number: 20050008346
    Abstract: A recording apparatus comprises a recording device, a changing device, a storage device and a control device. The recording device records recording data on a recording medium. The changing device receives a plurality of recording media supplied from an outside, selects one of the plurality of recording media as received and replaces the first recording medium loaded in the recording device with the second recording medium as selected. The storage device stores, during replacement of the first recording medium, the recording data recorded thereon. The control device controls the recording device and the changing device, monitors a remaining recording capacity or recording time of the first recording medium during recording, causes the first recording medium to be replaced based on monitoring results, and reads, after completion of the replacement of the first recording medium, the recording data of the first recording medium from the storage device and records same on the second recording medium.

  • Patent number: 6568066
    Abstract: A miniature motor includes: a plurality of magnets serving as stator poles and attached to an inner surface of a motor casing having a closed-bottomed cylindrical shape; a salient-pole rotor having a core mounted on a rotor shaft and windings placed on the core; and a commutator mounted on the rotor shaft. The core includes a center portion having a hole formed therein at the center for engagement with the rotor shaft, a plurality of leg portions extending integrally and radially from the center portion in equal number with the salient poles, and a plurality of wing portions, each extending integrally and symmetrically from an end of each of the leg portions. The core includes core laminations blanked from sheet steel and assembled together and is formed through deformation of the entire wing portions such that the radius of a circumcircle of the core coincides with a designed final radius of curvature of outer circumferential surfaces of the salient poles of the rotor.

  • Patent number: 5684529
    Abstract: A stereoscopic image displaying apparatus includes: field switching signal generating unit for generating a field switching signal alternately indicating odd field periods and even field periods from an original picture signal; delaying unit for delaying the original picture signal and producing a delayed picture signal; stereoscopic image signal generating unit for alternately selecting one of the original picture signal and the delayed picture signal in accordance with the field switching signal to generate a stereoscopic image signal; and display unit for displaying the stereoscopic image signal by alternately supplying pictures of the original picture signal to one eye of a user and pictures of the delayed picture signal to the other eye of the user on the basis of the field switching signal.

  • Patent number: 5270992
    Abstract: An apparatus for controlling rotation of a spindle motor includes a lock detection unit, a memory unit, a comparison unit, and a control unit. When the lock detection unit detects the lock state of the time base servo loop, a voltage corresponding to the frequency of a read RF signal is stored in the memory unit. When the control unit detects that the rotation velocity of the spindle motor greatly deviates from a normal rotation velocity, it effects a control so as to accelerate or decelerate the spindle motor in dependency upon a compared result of the comparison unit which makes a comparison between a voltage corresponding to the frequency of the read RF signal and a voltage stored in the memory unit.

  • Patent number: 5257253
    Abstract: A first reproduction circuit reproduces a digital stereo audio signal from a signal which is read by means of a pickup from a disc loaded at a playback position, and a second reproduction circuit reproduces an analog audio signal from the signal read by the pickup. When the disc loaded at the playback position is identified as being a Laser vision Disc with Digital sound (LDD) disc, the stereo audio signal outputted from the first reproduction circuit is mixed with the analog audio signal outputted from the second reproduction circuit, such that a vocal portion of a reproduction can be reproduced together with an accompaniment portion of the reproduction, in a stereo mode.

  • Patent number: 5202866
    Abstract: A digital audio disk player detects a peak position indicating a peak value of the recorded level over N pieces of music selected to be played alone or in sequence from multiple pieces of music recorded on a digital audio disk, and plays a predetermined interval including the peak position. The player can therefore set the optimal recording level at the time of dubbing programmed pieces of music or those music pieces which are edited by the editing function.

  • Patent number: 5177728
    Abstract: A disc player capable of playing discs of different types such as: discs where only a digital audio signal is contained in a first frequency band; discs where only an analog audio signal is contained in a frequency band other than the first frequency band; and, discs where digital and audio signals are contained in the first frequency band and the other frequency band. Processing arrangements are further included to determine (according to disc size and/or presence of a table of contents) whether a currently loaded disc is recorded in the same format as a previous disc which was loaded immediately prior thereto, and if the same, playing the currently loaded disc according to the same reproduction settings as those for the previous disc.

  • Patent number: 5172354
    Abstract: The present invention relates to a compatible disk player, which is capable of playing compact disk CD or laser disk LD. More specifically, the disk player of the present invention reduces the delay time between loading and actually playing a disk. It includes a manual switch on the disk player, from which a person may select the type of disk to play, thereby decreasing the time needed to determine which type of disk is entered. If the CD mode is selected or the last disk to be played was a CD, the player pick-up is placed in the initial playing position of the CD before a disk is entered. After entering a disk, if it determines that an LD is loaded or the CD mode is cancelled (by the manual switch) the pick-up is moved to a ready position for the LD. By including a manual switch and circuitry which assumes the next disk type is the same as the last, the present invention reduces the time needed to determine which type of disk is loaded.

  • Patent number: 4953212
    Abstract: An auto voice changing apparatus receives music from a stereo or multi-sound, digital or analog recording and either plays the recorded music as is, or uses the recorded music as instrumental accompaniment by eliminating the vocal sounds from the reproduced music and substituting vocal sounds provided through a microphone. The control is based solely on a single auto voice switch, control information from the recording, and detection of vocal sounds from the microphone.
