Abstract: This invention is intended to be capable of accurately detecting whether an electric device is in a stand-by mode or power stoppage occurs. An electric device 20 includes a power supply circuit 12, a power stoppage detection circuit 15, and a control microcomputer 10. The power stoppage detection circuit 15 generates a detection signal based on a voltage input from the power supply circuit 12. This detection signal is input from the power stoppage detection circuit 15 to the control microcomputer 10. The control microcomputer 10 detects a state of an operation of the power supply circuit 12 based on the detection signal input from the power stoppage detection circuit 15. If the detection signal is not detected for a constant time or more, the control microcomputer 10 determines that the power stoppage occurs to the power supply circuit 12.

Abstract: When a content title recorded on a storage medium is automatically deleted to secure a space for recording an additional title, deletion of the title can occur contrary to user's intention. Storage schedules for recorded content titles, especially the storage schedules concerning operations for the content titles are initialized, and a content title set to have no storage schedule is preferentially automatically deleted. Thus, the recorded content is not deleted contrary to the user's intention.

The clock correction processing section 7 compares data on time counted by the clock count section 6 with the correction time information, and thereby corrects the clock count section 6.

Abstract: This invention detects an operating voltage output from a power supply circuit of an electric device using a control microcomputer, and makes a power supply detection circuit protecting the control microcomputer from an overvoltage and, a reduced voltage, compact. The power supply detection circuit includes a first circuit, a second circuit, and a third circuit. The first circuit includes a first switching element. The second circuit includes a first voltage detection element and a second switching element. The third circuit includes a second voltage detection element and a third switching element. If a proper voltage is output from a voltage output terminal, the third circuit is made continuous, thereby turning on the first switching element and inputting a proper voltage signal to a power fail terminal of the control microcomputer. If an overvoltage is output, the second circuit is made continuous and the power fail terminal is set at a ground potential, thereby protecting the control microcomputer.

Abstract: While viewing a program, a viewer can check the other program at arbitrary timing. While a program on a channel received by a first tuner 1 is being output, when a commercial starts or a start signal is input from an operation portion 6, an output of the program is changed to that of a program received by a second tuner. The viewer can select either outputting the program on the channel designated by the second tuner 2 or sequentially changing channels received by the second tuner 2 and sequentially outputting different programs according to a viewer's desire. When the commercial is over or an end signal is input from the operation portion 6, the output is changed to that of the program received by the first tuner 1 and the original program is output.

Abstract: After special reproduction is executed, a position of data is promptly returned to a reproduction position at the start of the special reproduction by simple operation and normal reproduction is started at this reproduction position. If the special reproduction is executed during the normal reproduction, the special reproduction is started after the reproduction position at the start of the special reproduction is stored in a memory. If a point key is input while the special reproduction is being executed, after the special reproduction is stopped, or while the normal reproduction is being executed after the special reproduction is stopped, the reproduction position is read from the memory. The normal reproduction is started after moving the position of the data to this reproduction position.

Abstract: This invention enables moving whichever position of a file recorded on a recording medium to a designated position by simple operation and starting reproduction. The number of times of operation of a rapid traverse key or a rapid return key input in a reproduction stop state are counted. If the number of times of operation is two or more, there is a simple reproduction command. Time is designated according to this number of times of operation. If the present position in the reproduction stop state is moved forward or backward by as much as the designated time and a position corresponding to the designated time is detected, the reproduction is started.

Abstract: This invention enables setting an RF output channel to a desired channel with a simple operation. A number key on a remote controller is depressed for long time of three seconds or more as an operation other than an ordinary operation for the number key. If a control portion detects a setting signal generated by thus depressing the number key for the long time, the control portion determines whether a channel corresponding to the operated number key is vacant. If the channel is vacant, the control portion sets the channel as the RF output channel. If the channel corresponding to the depressed number key is not vacant, a vacant channel is searched. If there is a vacant channel, the vacant channel is set as the RF output channel.

Abstract: A cathode ray tube deflection yoke is provided wherein the deflection yoke includes a plurality of deflection coils. One or more of the deflection coils have a non-constant distribution of turns, whereby an electron beam passing through the deflection yoke is deflected by a magnetic field that varies according to different numbers of turns relative to position of electrons of the electron beam between the entrance and exit of the deflection yoke. The non-constant turns distribution may be linear or non-linear, may be monotonic or non-monotonic, and/or may have a positive or negative turns bias, either in whole or in part. The horizontal deflection coil and/or the vertical deflection coil, or both, may have a non-constant turns distribution.

Abstract: A cathode ray tube includes an electron gun directing electrons towards a faceplate having an electrode biased at screen potential. The electron beam is magnetically deflected to scan across the faceplate to impinge upon phosphors thereon to produce light depicting an image or information. A neck electrode near the tube neck is biased at or below screen potential and a second electrode between the neck electrode and the faceplate is biased at or above screen potential. As a result, the electrons are deflected over a greater total angle than is obtained from the magnetic deflection. A third electrode proximate the faceplate is biased at or below screen potential to direct electrons towards the faceplate, thereby to increase the landing angle of the electrons thereon. A metal and ceramic support includes a resistive voltage divider to which ones of the electrodes connect.

Abstract: In a cathode ray tube, an electron beam is directed towards a faceplate having an electrode biased at screen potential and is magnetically scanned across the faceplate to impinge upon phosphors thereon to produce light depicting an image. A six-pole coil is disposed proximate the deflection yoke and/or on the tube neck to modify the focus of the red, green and blue electron beams to control focus. An electrode between the tube neck and the faceplate is biased at or above screen potential to deflect electrons over a greater total angle than is obtained from the magnetic deflection.

Abstract: A main lens of an electron gun of a cathode ray tube is provided. The main lens for receives a plurality of parallel and co-planar electron beams emitted by the electron gun. The lens focuses each electron beam along a respective one of a plurality of focal axes incident to a display surface. A first grid electrode is positioned substantially orthogonally with respect to the plurality of electron beams, the grid electrode includes a plurality of apertures.

Abstract: The present invention discloses a flat display.The flat display is obtained by sealing an electro luminescent display which emit red and green light to a plasma display panel which emit blue light. One discharge space formed in the plasma display panel holds the red and green luminescent patterns in the electro luminescent display in common.

Abstract: The focusing characteristic of this electron gun is not impaired by the aberration caused by the deviation from the centers of the holes on both sides of the main lens, through which the electron beams pass, and the astigmatism of the electron beams due to the uneven magnetic field such of a deflecting yoke when the electron gun is in operation. In the focusing electrode 1 of the electron gun a assembly, a plurality of focusing grooves are formed parallel to the direction in which the electron beams pass. A plurality of additional electrode members, each consisting of a flat thin plate, are inserted into the focusing grooves, respectively.
