Title: Channel selection system for television receiver
Inventor: ITSUKI ISAMU
IPC: H04N5/44
Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To provide the channel selection system for a television receiver that selects a receptible broadcast wave without troublesome operations when reception state is changed. SOLUTION: When a search control section 30 detects that a broadcast wave received at present is not receptible, the control section 30 gives an instruction to a frequency sweep section 32, which starts a frequency sweep operation and searches a receptible broadcast wave at that time, based on an SD signal from a reception level detection circuit 58 to generate a channel selection list, including receptible electric field levels and channel numbers of receptible broadcast waves. After the end of search, the search control section 30 reads a channel number of the broadcast wave in the order of higher reception electric field levels, sequentially receives the contents of the program and displays the contents and sounds the output.  When an enter key of an operation section 60 is depressed on the way of channel selection, the control section 30 confirms the reception state of the broadcast wave at that time.

IPC: H01T19/00
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To obtain a solid ion generator causing no burning, fuming or ignition even if a part with low impedance between 1st and 2nd electrodes exists locally owing to unevenness in the interval between the electrodes or variation in the dielectric constant of a dielectric layer by supporting a resistor layer on an insulating substrate so that it is connected to one or both of the electrodes in series. SOLUTION: A dielectric layer 4 is disposed on an insulating substrate 1. A 1st electrode 2 is disposed on one side of the dielectric layer 4 and a 2nd electrode 5 is disposed on the other side so as to generate ions by a gaseous discharge between the electrodes 2, 4. A resistor layer 3 is directly or indirectly supported on the insulating substrate 1 so that it is connected to one or both of the electrodes 2, 5 in series. Since the electrodes 2, 5 are connected to an AC power source through the resistor layer 3, even if unevenness in the interval between the electrodes or variation in the dielectric constant of the dielectric layer occurs, an overcurrent is prevented from flowing locally in a part with low impedance.
