摘要： A security device prevents an audio apparatus for reproducing sounds recorded on a disk from being kept locked when the apparatus cannot read TOC information because the disk has a defect or the apparatus fails. The security device cancels the security operation in accordance with the results of comparison of the read TOC information with prestored TOC information. When it is detected (R1-R4) that the disk or apparatus is abnormal during the reading of the TOC information, the security device stops the judgment on the TOC information. Therefore, the audio apparatus is not locked in a TOC information reading state. The TOC information read (R5) without mechanical error is correct.

摘要： An audio system mounted on an automobile. An acoustic reproducing device comprises a fader control circuit that separates acoustic signals into predetermined channels and adjusts the levels of the separated acoustic signals depending upon the position of a fader control, a sound-field control device for processing acoustic signals obtained from the fader control circuit to establish a desired sound field in the car room, and a means for canceling the separation of acoustic signals that has been effected by the fader control while the sound-field control device is in operation. When the sound-field control device is turned on, the effects of a balance control and the fader control are removed. Therefore, the sound field of a balance control and the fader control are removed. Therefore, the sound field is automatically adjusted to the center position even if these controls are deviated from their center positions, and the sound-field control device exhibits maximum effects.

摘要： An antenna coil (21) for generating a magnetic field (25) to supply power to a transponder (26) is energized through switching devices (23 and 24) connected between Vcc and GND of a D.C. power supply (20) and having contacts S1 and S2 that are actuated in opposite phases in accordance with a carrier signal. Both of the switching devices (23 and 24) are turned OFF while the carrier signal is absent. Accordingly, the oscillating current flowing through a series resonance circuit of the antenna coil (21) and a capacitor (22) quickly attenuates and the intensity of the magnetic field (25) drops, too.

摘要： Input signals are guided into a first signal path which includes a variable low-pass filter, and into a second signal path. A control circuit so controls that the cut-off frequency of the variable low-pass filter changes with the frequency of the input signals. When the noise is being generated, the output signals are obtained through the first signal path. When no noise is being generated, the output signals are obtained through the second signals path.

摘要： A circuit for sensing pulse-like noises entering an AM receiver, by which the freedom of a configuration is improved and malfunctions are prevented. The circuit, which is used in an AM receiver, provided with an evelope detector (108) for envelope-detecting the intermediate frequency signal, and outputs a gate signal for removing the pulse-like noise signal included in the output signal of the envelope detector (108), includes a high-pass filter (31), an amplifier (32), a level sensing section (33), and a band-pass filter (34). The first high-pass filter (31) blocks an envelope-detected signal fed from the envelope detector (108), and extracts the pulse-like noise signal from the output signal of the envelope detector (108). The amplifier (32) amplifies the extracted pulse-like noise signal. The level sensing section (33) senses the level of the amplified pulse-like noise signal, and when the level exceeds a predetermined value, outputs the gate signal. The band-pass filter (34) extracts the envelope-detected signal from the output signal of the envelope detector (108), adjusts the amplification factor of the amplifier (32) and controls the level of the pulse-like noise signal to a fixed value.

摘要： In transferring data between a plurality of electronic devices, the problem has existed that the system becomes large and causes a low transfer rate, for example, because some system components idle in particular situations during the transfer operation. According to the present invention, the data transfer operation relies more on hardware and less on software. Furthermore, the system components are more effectively utilized. This helps increase the data transfer rate and the accompanying signal processing rate, thereby providing a relatively small system.

摘要： An apparatus having a mantissa part register and an index part register which transfers floating point data only is now permitted to input and output fixed point data, too. The registers are connected to individual inputs and outputs and also receive a common clock signal. Depending on the input and output data format the registers are used separately or in combination. With the registers being separately used, increased kinds of input and output data can be processed simultaneously. In the event of a data length longer than the register length, a combination of registers can be used to accommodate the data.

摘要： In a vehicle control device (1) having a so-called key-less entry system wherein a door lock control portion (6) controls an actuator (43) for door locking by receiving a signal sent from a transmitter (41) which denotes an identification code, an internal combustion engine control portion (3) calculates a fuel injection volume and an ignition timing from control data stored in a memory (20) in response to the results of detection by respective detectors (11, 12) to thereby drive a fuel injection valve (13) and an ignitor (14). The door lock control portion (6) detects whether or not the vehicle is burglarized based on the switching conditions of respective switches (63, 44, 45) and imparts the detection results to a constant voltage circuit (67) of the internal combustion engine control portion (3) as a code signal. When it finds that the vehicle is burglarized, power supply to the respective circuits in the internal combustion engine control portion (3) is cut off. In addition, the door lock control portion judges whether or not an identification code stored in the memory (20) in advance coincides with an identification code received by a receiver (42), and when it finds that they do not coincide with each other, the start of an engine (2) is disabled. Therefore, since it is not a binary signal allowing or not allowing the engine to be started but an identification code that cannot be produced simulatively that is inputted to the control portion (3), it is possible to securely prevent the vehicle from being driven away by a thief.
