Abstract: PROBLEM TO BE SOLVED: To detect the reception of a color television signal encoded according to the SECAM standard by using a filter pre-tuned by a general control of the filters in an integrated circuit for identifying a standard for encoding a signal. SOLUTION: An output of a filter 6 is a signal which can be used by a detector 7 which detects a standard. This signal is transmitted to a first input IN of the detector 7, and a signal encoded by the SECAM standard is detected. An output of a gain stage 8 is transmitted to a wide area filter 9 whose Q is high and whose two terminals are pre-tuned to cut-off frequencies for adjustment. The pre-tuned terminals receive a signal CT corresponding to the general control for the filter of an integrated identifying circuit. The filter 9 is pre-tuned by a control common to all the filters in the integrated circuit. That is, the theoretical cut-off frequencies for the filter 9 are fixed between two chrominance carrier frequencies of the SECAM standard.

Title: Device for informing of exchange time of back light for liquid crystal display
Inventor: MORIAI SHINSUKE
IPC: G02F1/133
Filed: 1994-11-29
Abstract: PURPOSE: To inform a user of a proper exchange time of a back light by detecting a judging element correlating with the deterioration in the back light for liquid crystal display and judging whether or not it has arrived at the exchange time by comparing the detected value with a reference value. CONSTITUTION: A timer 13 is started, and a CPU 10 operates a life judging data value of a fluorescent tube 8. The life judging data value is calculated using a consumption time obtained accumulating the product between the applied voltage of the fluorescent tube 8 and a use time under the applied voltage and the number of times of switching. Then, when the CPU 10 judges that the calculated life decision data value has exceeded a beforehand stored reference value, the CPU 10 outputs a display command signal to display an exchange warning to a display drive circuit 18, and displays that it is the exchange time of the back light 8 on a liquid crystal screen. Thus, since the fluorescent tube 8 is exchanged for a new one in the proper time, it is prevented that the fluorescent 8 is cut in use, and the use of a pen input device is interrupted on the way.

Title: Digital data recording/reproducing device
Inventor: OKABE MASAO
IPC: G06F3/06
Filed: 1990-11-02
Abstract: PURPOSE:To enable reproduction to be in disabled state and security of data to be retained positively by disabling correction when performing error correction as far as no proper keyword data is set at the time of reproduction. CONSTITUTION:Data conversion is performed to an entire coded data where error correction coding processing is performed and redundancy data is added and it is recorded on a tape. At the time of reproduction, a coded data which should have been recorded is restored by performing inverse conversion with the same keyword as a conversion keyword which is used at the time of recording. When a keyword data which is different from the keyword data which is set at the time of recording is set at the time of reproduction, original coded data cannot be retrieved when performing inverse conversion of data and it becomes quite meaningless data as an error correction symbol so that a situation, where errors occur in nearly all data, occurs when correcting errors, a read processing exceeding the limit of correction capacity is performed, no proper reproduction is made regardless of reading, and error messages are returned to an external device as disabled reproduction, thereby completing reproduction.

Title: Volume controller for on-vehicle acoustic device
Inventor: WATANABE EIJIRO
IPC: B60R11/02
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To eliminate the induction noises which are caused in a data transfer mode and offensive to the ears of listeners by using a control data sending means which repetitively sends the control data to a volume and a sending interval control means which varies the sending interval of the control data via the control data sending means. SOLUTION: A random number generation part 3 generates a random number and sends it to a control part 2, and the part 2 decides the time (sending interval) set between the preceding and next sending operations of data based on the received random number. These random number and sending interval are previously turned into the maps, etc., and stored at the part 2. Then the part 2 sends the volume data to a volume IC 1 or stands by according to a fact whether a prescribed time elapsed or not. As a result, the controlled acoustic signals are outputted from the IC 1 at a random interval set based on the random number. Accordingly, the noises are also induced at random to an audio equipment and heard at random. Thus the noises can be aurally reduced.
