Abstract: A video signal is supplied from a digital VTR 1 and is encoded by an MPEG encoder 8. The encoded video signal is recorded as a compressed video signal in an HDD 9. A plurality of compressed video signals are recorded in the HDD 9 and addresses of the compressed video signals are stored in a controller 6. MPEG decoders 12 and 14 decode the compressed video signals which are read out from the HDD 9. After a video signal processing apparatus 3 executes an editing process on the decoded video signals, a synthesized video signal is supplied to a digital VTR 10 through a switch 7. The synthesized video signal recorded in the digital VTR 10 is supplied to the video signal processing apparatus 3 for further processing through a switch 13 without being decoded.

Abstract: A method and apparatus for updating a memory in a Compact Disc changer. Information identifying discs stored in a CD changer is stored in a memory. The memory is updated when a CD is loaded which does not have identifying features which are recognized by the CD changer. Updating is carried out via a modem connection to a remote database. The database can be stored locally in a local database residing in a personal computer where the database can be queried to locate desired tracks and can be used to facilitate control of the compact disc changer by providing a simplified interface for building a play list and the like.

Abstract: An improved squeegee for a screen printing system. A squeegee with two substantially rectangular shaped elements adjacent each other and each having a longitudinal axis. The longitudinal axes are not aligned and instead intersect at an angle unequal to zero. Alternatively, the improved squeegee for a screen printing system may include a center section with outward projections, a first substantially rectangular shaped element adjacent the center section and having a first longitudinal axis and a second substantially rectangular shaped element adjacent to the center section and having a second longitudinal axis, the first longitudinal axis and the second longitudinal axis intersecting at an angle unequal to zero.

Abstract: An apparatus for rotating an article includes a first housing member mountable on a side of the article conveyor, and a second housing member mountable on the opposite side of the article conveyor. A motor having a shaft is mounted on the first housing member. The motor is arranged to drive a frictional drive roller. The frictional drive roller in turn drives a first end portion of an approaching article. A pin is mounted on the second housing member and arranged to contact a second end portion, i.e., a second end portion opposite the first end portion, of the article while the frictional drive roller drives the first end portion. The pin functions to inhibit motion of the second end portion and thereby establishes a pivot position about which the article rotates approximately ninety degrees.

Abstract: A method for high speed playback of digital video data (e.g. D1 or D2 data) in which, at lower speeds, the frames of data to be played back are made of a mixture of consecutive frames of data. The frames of data are mixed by averaging the pixel values over consecutive frames to make up the output frames. For high speed shuttle operation, non-consecutive frames are averaged on a pixel by pixel basis to create shuttle frames. In order to improve the appearance of the output, consecutive shuttle frames contain a common original frame so that a component of the original data spans two output frames.

Abstract: A wireless voice messaging device including a cassette-shaped body adapted to be inserted into a cassette player in lieu of a cassette. A receiver for receiving incoming call signals including at least one incoming voice message, a memory for storing the incoming voice message and recalling the incoming voice message in response to a first control signal, and a transducer for establishing an operative connection with a play head of the cassette player for transferring the incoming voice message recalled from said memory means to said play head are all disposed in the cassette-shaped body. A control signal generator, also disposed in the cassette-shaped body and responsive to operation of said cassette player, is provided for detecting a mode of operation of the cassette player and controlling a mode of operation of the voice pager in response thereto. A transmitter, disposed in the cassette-shaped body, is provided for transmitting outgoing voice messages.

Abstract: A method and apparatus for creating an optical disk mother or stamper wherein the number of processing steps is greatly reduced from the prior art methods. In particular, the present invention involves directly forming a mother or stamper by direct laser ablation of a conductive metal substrate. More specifically, a stream of coded digital information (for example, representing the content of an encyclopedia in the case of CD ROM or a classical music collection in the case of CD audio) is converted into a corresponding plurality of pits and lands in the conductive metal substrate by electronically switching the beam of a first laser on and off via an electro or acusto-optic modulator (EOM/AOM) in response to the digital information. As a result, selective portions of the conductive substrate are either ablated (in the case where the laser is on) thereby directly creating the pits, or the substrate is left unaltered (in the case where the laser is off) thereby creating lands.

Abstract: A super high resolution rotary optical encoder having as its disk an optical disk, i.e., a disk employing the optical principle of non-contact readout based on diffraction theory.

Abstract: An optical disc player adapted to read an optical disc having a plurality of pits and lands representative of information stored on the optical disc; the optical disc being at least in part unmetallized. The player includes a semiconductor laser for generating a variable power laser beam, the power of the beam being controlled by a control signal applied to a control terminal of a semiconductor laser driver. A focusing servo is provided for focusing the beam on the optical disc such that a portion of the beam is reflected back from the optical disc indicative of the pits or lands. The portion of the beam reflected back from the optical disc being substantially less from unmetallized portions of the disc than from metallized portions of the disc. The focusing servo has a focal point constrained to lock on a pit plane of the optical disc.

Abstract: A television system which selectively receives additional information multiplexed in a video-signal source different from and other than a video-signal source currently being watched. A video signal V7 supplied to a CCD/EDS data extractor 7 is selected independently of a video signal V5 for a main screen of a CRT 10 or a video signal V6 for an auxiliary screen of the CRT 10 displayed by a PinP (PoutP) function. Accordingly, captions to be displayed are not limited to additional information multiplexed in the video signal V5 for the main screen displayed on the CRT 10. As a result, additional information multiplexed in a video signal for the auxiliary screen other than that for the main screen or multiplexed in an external video signal V2 can also be displayed as well.

Abstract: A demagnetizer for display unit which allows to reliably demagnetize without bothering the user thereof. A start pulse a1 is sent out from a timer 21 to an activating pulse generating circuit 22 in every predetermined time t1 to sent out an activating pulse b. Receiving the activating pulse b, a demagnetizing current generating circuit 23 sends out a demagnetizing current I to a degauss coil 1 to demagnetize a magnetized shadow mask (or aperture grille). The activating pulse b is also supplied to a reset pulse generating circuit 24 to send out a reset pulse c to the timer 21. Thereby a counting of the timer 21 is reset and the start pulse a1 is sent out as the predetermined time t1 elapses. This demagnetizer allows to carry out the demagnetizing action without bothering the user.

Abstract: An improved squeegee holder for screen printing. A squeegee with a diamond or square shaped portion is clamped between two clamping plates inside V-shaped grooves in the clamping plates. Corner relief portions are provided within the clamping plates so that the corners not in use are not damaged. The clamping plates are aligned by two alignment pins and screwed together by a threaded rod with a handle. A spring surrounds each of the alignment pins urging the two clamping plates apart so that they separate when the screw handle is loosened.
