  • Patent number: 6002924
    Abstract: A full-spectrum, multi-mode radio receiver provides truly continuous coverage of reception of radio signals in a variety of modes or formats, and in a frequency range extending from about 10 kHz to about 2600 MHz. That is, there or no frequencies or frequency bands within which reception is not possible or is possible only with a reduced performance of the radio receiver, because of spurs, inter-modulation products, or images. The radio receiver provides this broad-spectrum, continuous coverage of reception, and does so with a receiver front-end tuning selectivity to as little as 1 Hz.

  • Patent number: 5728776
    Abstract: When producing a graft modified polyolefin by melting and kneading a polyolefin, a radical-polymerizable monomer and a radical-polymerization initiator, the producing efficiency is improved. The grafting reaction is effected by feeding the melted polyolefin containing either one of said radical-polymerizable monomer and the radical-polymerization initiator to the other. When said radical-polymerizable monomer is an unsaturated carboxylic anhydride, said unsaturated carboxylic anhydride as a starting material is preliminarily heated at 50.degree. to 250.degree. C., and then fed to the grafting reaction mentioned above. When the monomer is an unsaturated carboxylic acid or an acid anhydride of such an unsaturated carboxylic acid, an organic peroxide of a formula (I) is used as the radical-polymerization initiator. ##STR1## In this formula (I), two substituting groups connected directly to the benzene ring have an ortho-positional relationship or a meta-positional relationship, R.sub.1, R.sub.2, R.sub.3, R.sub.

  • Patent number: 5552833
    Abstract: A method and system in which television-program table information is transmitted using teletext formats in a coding transmission system. On the reception side, reservation of video recording with an image recording apparatus is effected by making use of the transmitted television-program table information. Reserving a recording time is accomplished using a program recognition device 9 which detects that the television-program table information has been transmitted. Further, a program update recognition device 10, a channel information processing device 11, a date information processing device 12, a time information processing device 13, a program code information processing device 14, and a title information processing device 15 serve to process their respective information in order to display the television program table on a display unit. Once displayed, a television program desired for video recording is selected by a cursor display device and selection device 19.
