Title: Diagnosis system of magneto-resistance effect type head
Inventor: ARAI SHINICHI
IPC: G11B5/02
Filed: 1983-12-12
Abstract: PURPOSE:To simplify the diagnosis of an MR head by extracting a high frequency signal out of a preamplifier in accordance with the resistance value of the MR head. CONSTITUTION:A constant current is supplied to an MR head 1 from a constant current source consisting of a transistor (TR) 201 and its peripheral circuits. At the time of diagnosis, a drive circuit 204 is driven by the output 13 of an oscillator and a resistance 205 is turned on and off to vary the base potential of the TR201 at a high frequency. As a result, a high frequency signal having an amplitude proportional to the resistance value of an MR head film is produced at an MR head output terminal 207. This high frequency signal is supplied to an amplifier 203 via a capacitor 202. When a control circuit 8 receives a diagnosis start command 16, the output given from the head 1 is amplified by a preamplifier 2 (203) and then compared with the reference voltage 14 through an amplitude detector 6. Then the circuit 8 decides the quality of the head 1 based on the output 15 of the detector 6 and reports the diagnosis result 17 to an upper device.

Title: Semiconductor integrated circuit
Inventor: NATSUME MITSUAKI
IPC: H03K19/018
Filed: 1982-12-29
Abstract: PURPOSE:To perform a short circuit test or an input characteristic test despite a pull-down resistance inserted between an input terminal and a VEE power supply, by connecting forward a diode between a pull-down or pull-up resistance and the power supply. CONSTITUTION:The anodes of diodes D1 and D2 are connected to a terminal of pull-down resistances RP1 and RP2 respectively of an ECL integrated circuit 3, and at the same time the cathodes of these diodes are connected to a VEE voltage source. Thus currents i1 and i2 are not flowed between input terminals 1 and 2 despite the voltage for short circuit test applied between pins. As a result, it is possible to perform a short circuit test between pins or an input characteristic test even though a pull-down or pull-up resistance is connected between the current of the circuit 3 and the input terminal. In addition, the input can always be set at a low level in a state where the pull-down or pull-up resistance is applied.

IPC: H03L7/087
Filed: 1985-10-18
Abstract: PURPOSE:To improve the control by detecting a phase difference between a reference input and an output of a voltage controlled oscillator (or its frequency division output) at a prescribed tie, generating an output having a pulse width corresponding to the phase difference, obtaining a difference between a preceding output and a succeeding output and integrating the difference in a capacitor so as to narrow the loop gain band sufficiently. CONSTITUTION:When a voltage controlled oscillator 1 oscillates a specified frequency and the local clock frequency is coincident with the reference clock frequency, input pulses at both terminals I1, I2 of a charge pump 8 are opposite in polarity but same in the pulse width, then a mean value of an output current from a terminal O is '0' and a terminal voltage of a capacitor 9 is kept to the central value of a control voltage from the voltage controlled oscillator 1 when the frequency of the local clock is lowered, the input pulse width at the terminal I2 is longer than the pulse width at the terminal I1, the mean value of the output current from the terminal O is negative and the terminal voltage at the capacitor 9 is lowered. The oscillating frequency of the voltage controlled oscillator 1 rises and the input pulse width at the terminal I2 is decreased and the local clock frequency is restored to a frequency equal to that of the reference clock.

Title: Recorder for video signal and audio signal
Inventor: SHIGENOBU MASAHIRO
IPC: H04N19/00
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To evade the variance of amplitude and also to use an ATRAC encoder and an ATRAC decoder which are used currently by recording the video and audio signals on a storage medium synchronously with each other for each GOP after compressing both video and audio signals via the MPEG and ATRAC respectively. SOLUTION: The video and audio data are compressed by an MPEG 2 and an ATRAC respectively. At the same time, the sound group position information to which the dummy data are added by the dummy data adding means 80 and 81 are stored in the header information and recorded on a recording medium. Then both video and audio data are recorded sequentially on the recording medium for each GOP. The header information, the compressed video data equivalent to a single GOP and then the audio data equivalent to two channels are recorded in a single GOP period. Thus, the amplitude never causes any variance when the sample number of every sound group is multiplied by a fixed window number and then synthesized.
