    Abstract: PURPOSE:To display visual information by reproducing digitized information on a subsignal track, relating to the audio signal of a main signal track, by a subordinate reproducing head and displaying it on a display part through a reproducing circuit part. CONSTITUTION:A tape recorder 10 is equipped with heads which perform recording to and reproduction from main signal tracks 2a and 2b of a magnetic tape 1, and a subordinate recording head and a subordinate reproducing head which perform recording to and reproduction from one subsignal track 3 formed in the center of the tape 1 in the running direction. On this track 3, various pieces of information on audio signals of the main signal tracks are digitized and recorded in the form of numbers, alphabets, etc. Those pieces of information on this track 3 are extracted the subordinate reproducing head and a reproducing circuit part that the recorder 10 has, and then displayed on a display part 21 such as a liquid-crystal display device. Thus, while the audio signals are reproduced, various pieces of visual information relating to them are displayed.

    Abstract: PROBLEM TO BE SOLVED: To provide a centralized communication control system and a method capable of performing polling communication without being affected by interruption communication, and capable of keeping a polling cycle time constant.
    SOLUTION: There are included one master device 20, a communication bus 40 and a plurality of slave devices 30-1 to 30-X connected with the master device 20 via the communication bus 40. The master device 20 and the plurality of slave devices 30 are capable of performing two-way communication via the communication bus 40. Communication is then performed by performing at least a polling communication from the master device 20 to each slave device 30 and an interruption communication from each slave device 30 to the master device 20 on different channels while multiplexing them on the same line.

    Abstract: PROBLEM TO BE SOLVED: To improve the operability while keeping the insertion attitude of a disk cartridge constant and also to prevent the mechanical part from being damaged, by forming the loading mechanism by which one end of a disk cartridge holder at the inserting port side is freely turnably held. SOLUTION: When the disk cartridge is inserted to the cartridge loading mechanism 7, an eject member 17 is slid forward and a cam pin is moved to the inclined part from the horizontal part of a cam hole, and the cartridge holder 16 is turned counterclockwise making a supporter 15 as the fulcrum, then the loading mechanism 7 becomes in the horizontal state. The cartridge loaded into the loading part 16e is thereby made to be in the fixed state to position the cartridge, and also a recording/reproducing mechanism and a disk driving mechanism are entered from an opening part for recording/reproducing and an opening part for driving which are opened by a shutter driving lever 18, then the cartridge is pressurized downward by a pressurizing member 20. Meanwhile, the cartridge holder 16 at the time before the cartridge is inserted, is in the front down state slightly turning clockwise by an eject spring 21.

    Abstract: PROBLEM TO BE SOLVED: To perform gain control with high accuracy, without being affected by power supply voltage and temperature fluctuations by providing a gain control voltage generation circuit and a gain control amplifier, etc., which set gain in accordance with gain control voltage, amplifies an input signal and then outputs it. SOLUTION: A gain control voltage generation circuit 31 receives a control voltage VCONT through a control IC 20 and also reference voltage VREF. Then for the gain of a gain control amplifier 32, a gain control voltage VC which is decided by a voltage ratio VCONT/VREF of not only the control voltage VCONT but also of the reference voltage VREF is supplied to the amplifier 32. Thus, because the amplifier 32 sets a gain based on the voltage VC, it is to affected by a power supply voltage and the temperature fluctuation and can perform gain control with high accuracy.
