Abstract: A cathode-ray tube according to the present invention is able to automatically correct a color shading caused due to a repulsion effect and the like, which occurs between electron beams. An electron gun for use with the cathode-ray tube according to the present invention includes beam apertures bored through a first electrode opposing a cathode disposed in an inline fashion. Further, beam apertures through which so-called side beams pass are bored with a predetermined inclination relative to the opposing cathodes. Consequently, an electron lens formed between the cathode and the first electrode becomes an axial-asymmetric electron lens. The curvature of this electron lens is changed in response to a drive voltage of the cathode. When this curvature is changed, the trajectories of electron beams are changed to cancel an influence caused by a repulsion effect. Thus, a color shading can be corrected automatically.

Abstract: A video recording apparatus having a storage means to store program reservation data and equipped with a reserved recording function which utilizes program ID superimposed on broadcast signal. This apparatus includes a time difference table to store data of time differences between the sites of broadcasting stations and a receiving site, and when the program ID is to be stored as reservation data, the program ID is corrected with reference to the time difference table and then the corrected data is stored. The program ID inputted as reservation data represents the hour at the receiving site. Therefore, even when PIL data are mutually different due to the time difference between any selected broadcasting station and the receiving site, reserved recording of a desired program can be performed exactly on the basis of PDC or VPS with mere setting of the relevant country by a user, hence enhancing the operability and reliability of the apparatus.

Abstract: A cathode ray tube including a color selecting, electrode having a plurality of metal tapes; a rectangular frame for holding the color selecting electrode under tension; a plate spring having one end fixed to the frame and the other end having an engaging hole; and a panel having a pin for engaging the engaging hole of the plate spring, the panel being held to the frame by the plate spring; wherein a resonance frequency of the plate spring is different from a resonance frequency of the metal tapes. Since the resonance frequency of the plate spring is different from the resonance frequency of the metal tapes, possible resonance of the metal tapes with a large amplitude by the vibrations of the plate spring due to external vibrations applied to the cathode ray tube can be prevented. Therefore, even though the color selecting electrode has a fine pitch with a large screen and a high definition, the cathode ray tube has vibration resistance to prevent color deviation or the like due to the vibrations.

Abstract: A data recording and reproducing apparatus for recording and reproducing video signals in a plurality of formats with different rates to/from a record medium is disclosed. In the data recording and reproducing apparatus, a video signal in a selected format is converted into video data packets and audio data packets whose lengths are optimally designated corresponding to the selected format. With a video data packet and an audio data packet, a video sync block and an audio sync block whose lengths are different are formed, respectively. The video sync block and the audio sync block are encoded with respective error correction codes. The resultant data is recorded as record data to a record medium. Corresponding to the data rate of the video signal, at least one data packet is placed in one video sync block. A synchronization detecting apparatus automatically and accurately detects sync blocks with different lengths from a data sequence of record data reproduced from a record medium.

Abstract: A head positioning control apparatus and method which compensates for positional deviation of a magnetic head with respect to the positioning of the head on a particular track of a disc recording medium via a tracking control. Additionally, during a seek mode of the apparatus, a head that was positioned as a result of the tracking control is moved to a neighboring track of the disc recording medium. The seek mode uses the information obtained during the tracking mode to correct any disturbance frequencies occurring in synchronism with the rotational frequency of the disc recording medium, even if the head travels over a large distance.

Abstract: When a copy of music data recorded in an HDD to another electronic equipment is instructed, an accounting process is performed or a sound quality deteriorating process is performed based on a selection. When the accounting process is performed, after a predetermined accounting procedure is performed, a data copying process is performed and the data is outputted to a copy destination. When the accounting process is performed, a quality of the data is held to be almost identical to that of the original data. When the sound quality deteriorating process is selected, a data conversion is performed by a predetermined sound quality deteriorating process, the quality of the data is deteriorated, and the deteriorated data is outputted to the copy destination. In this case, the accounting is not performed. Where the data is moved, the accounting process and the sound quality deteriorating process are not performed.

Abstract: The package-side land 3a of a semiconductor package P1 is wholly exposed into the opening 5a of a solder resist layer 5. The board-side land 12a of the mount board B1 is also wholly exposed into the opening 13a of a solder resist layer 13.

When the lands 3a and 12a are set to be equal to each other in dimension and shape, the soldering layer 14a is shaped into a pillar having a substantially uniform section, thereby preventing local concentration of stress.
