  • Publication number: 20040242214
    Abstract: Provided is a call saving method and a telephone switchboard used in a telephone switching system capable of saving a call when an incoming call arrives at a portable telephone terminal via an access point and the portable telephone terminal does not respond. When the telephone switchboard detects no response of the portable telephone terminal to the incoming call, an access point that accommodates the portable telephone terminal within an access area makes an inquiry to a portable telephone terminal location management device, and, based on given operation rules, forwards the call going to the portable telephone terminal to a fixed telephone device arranged proximal to an access point specified in a proximal fixed telephone device list table.

  • Patent number: 4467462
    Abstract: A light beam emitted from a laser light source is made incident upon a video disc by means of an objective lens and a light flux reflected by the disc is made incident upon a light detector arranged in a far field of an information track of the disc. The light detector includes four light receiving regions divided in a track direction and a direction perpendicular to the track direction. A first sum of output signals from diagonally aligned two light receiving regions and a second sum of the remaining two light receiving regions are derived and then a sum signal and a difference signal of the first and second sums are formed. The difference signals are sampled by sampling pulses generated at positive going and/or negative going zero cross points of the sum signal to generate sampled values. A tracking error signal is obtained from sampled values.

  • Patent number: 4372504
    Abstract: This invention is for a tape cassette having window for insertion of a magnetic head and a pinch roller formed extending from a peripheral wall of the housing of the tape cassette to one of the holding plates which holds a pair of reel hubs in place. The device according to this invention has a shutter member, and a resilient metal wire housed in the housing. The shutter member has projections which are to be engaged with an engaging member provided on a tape cassette holder member of the magnetic tape transport apparatus. The metal wire urges the shutter member to close a portion of the window formed in the holding plate. When the cassette is loaded into the loading member, the projections engage with the engaging member and the shutter member releases the closing state of the holding plate forming portion of the window against an urging force of the wire.

  • Patent number: 4355750
    Abstract: First and second capstans are rotated at respective speeds by first and second motors. The speeds of revolution of the first and second motors are detected as detection signals, and the revolution speed of at least one of the first and second motors is controlled in accordance with a difference between the detection signals. An offset voltage is added to one of the detection signals corresponding to the revolution speeds of the first and second motors for the control of tape tension.

  • Patent number: 4180330
    Abstract: Light beams scans patterns of a subject copy, being reflected therefrom, and being converted into pulsating electrical signals. Color borders between two different colored patterns are detected based on the pulsating signals. On the other hand, a color of a predetermined scanned line following each of the color borders is sensed for determining the sensed color as a color between the adjacent color borders.

  • Patent number: 4090243
    Abstract: A color print painted with different colors C.sub.i (i = 1, 2 . . . n) is scanned by a color scanner along a plurality of successive line paths to generate a set of electrical signals each representing the intensity of the spectral components of the light reflected from an elemental area of the print. A macroscopic color separator is provided to generate a set of electrical signals each representing the average spectral intensities per unit area of the print. A data processor is used to compute the probability P(C.sub.i) from the data obtained from the macroscopic color separator and a set of mean spectral intensities exhibited by the color samples with which the print is painted by artisans. In accordance with the Bayes' Rule, the processor then executes computation of the product of P(C.sub.

  • Patent number: 4020502
    Abstract: A colored original which is painted with a plurality of predetermined colors is scanned along each of a plurality of line paths each of which can be divided into one or more colored line segments. Encoders are provided to characterize each of the line segments by a corresponding first code representing the color of the segment and a second code representing the run length of the segment. The first and second codes are sequentially recorded in a data file memory. The recorded information is repeatedly retrieved from the memory and transferred to a shift register. Line segments carrying the same color within each line path are detected by comparing the corresponding first code with a specified code. The second code is sequentially decoded into run lengths which are accumulated to measure the position of color transitions relative to the colored original. A video signal is generated upon occurrence of coincidence between the first code and the specified code.
