    摘要： The horizontal deflection apparatus has a separator whose cross-section takes a saddle-shape form, and horizontal deflecting coils are comprised of three coil groups connected in a series to each other. The first coil group is wound on the outermost circumference on the inside of the main structure of the separator, the second coil group is wound at a predetermined distance from the first coil group, and the third coil group is wound at a predetermined distance from the second coil group. Deflecting efficiency at the deflection center is improved because the deflection magnetic field generated from the second and third coil groups is generated at the deflection center.

    摘要： A telephone call selector in a telephone which comprises a memory circuit for storing a plurality of telephone numbers; an automatic dialing device operable to read out one of the telephone numbers from the memory circuit and to output a dialed signal representative of such one of the telephone numbers; a comparator for comparing a number, corresponding to a DTMF signal transmitted from a calling party subsequent to the receipt of a ringing signal generated from a local telephone of the calling party, with any one of identifier codes; and a loudspeaker device for emitting ringing sounds when the the number corresponding to the DTMF signal coincides with such one of the identifier codes. The telephone numbers stored in the memory circuit are utilized as the respective identifier codes.

    摘要： A side pincushion distortion correction circuit has an impedance circuit connected in series with the deflection coil in a television receiver. A controllable switch connected in parallel with the impedance circuit is operated by a switching signal, the phase of which is modulated by a combination of a parabolic signal at the vertical rate and a control signal corresponding to the brightness of a reproduced picture on the screen of the television receiver in order to maintain proper correction of side pincushion distortion despite variations in the brightness of a picture reproduced on the cathode ray tube of the television receiver.

    摘要： In an apparatus for converting received video signals of a first format, which has a first number of horizontal lines in a field or frame and a picture display of a first aspect ratio, to video signals of a second format, which has a second number of horizontal lines in a field or frame and a picture display of a second aspect ratio; an analog-to-digital converter converts the received video signals of the first format to digital video signals, a memory has addresses at which there are written at least a field of the digital video signals of the first format, whereupon, a reading circuit reads from the memory addresses less samples of the digital video signals than were written in the memory and the digital video signals thus read from the memory are converted back to analog form, and a controller is provided for variably determining a start address of the addresses in the memory from which video signal data are read. In the case where the first aspect ratio is larger than the second aspect ratio, the selection of the start address determines a portion or portions of the picture display of the first aspect ratio to be omitted at least at one side of the picture display of the second aspect ratio.

    摘要： The beam forming means and static convergence correcting means in a color cathode ray tube are arranged to provide for proper convergence of the beams at regions remote from the center of the screen and closer to the corners. The resulting misconvergence at the center of the screen is then corrected by dynamic convergence correcting means which produces less beam distortion then if it had to correct misconvergence at the corners.

    摘要： According to the party selecting circuit arrangement of a telephone of the present invention, an owner of the telephone can avoid a mischievous call or an erroneous call since it is so arranged that a call sound is discharged through the speaker only when the number given by the party other than the owner of the telephone is coincident with the telephone number stored as a secret number in the memory circuit of the telephone. Moreover, the party selecting circuit arrangement according to the present invention enables the owner of the telephone to identify the other party before he or she answers the call since an indicating element which indicates the number of the auto-dialing operation button provided correspondingly to the memory circuit storing the secret telephone number is turned on only at the above-described time.
