Patent JP-H04144409-A (JP)
Title: Amplifier
Inventor: TANAKA KUNITSUGU
IPC: H03F1/26
Filed: 1990-10-05
Abstract: PURPOSE:To improve an S/N by inserting a variable resistor between the base of an initial state transistor(TR) and the emitter of a post stage TR, and at the time of adjusting gain, reducing the influence of sliding noise of a variable resistor. CONSTITUTION:One fixed terminal of the variable resistor 7 is connected to the base of the initial stage TR 1 through the 1st capacitor 6, the other fixed terminal is connected to the emitter of the post stage TR 3 through the 2nd capacitor 8 and its variable terminal 9 is grounded. When the resistance value of the resistor 7 is reduced, the gain of a post amplifier stage is increased, but the gain of the initial amplifier stage is not almost changed. When the resistance value is increased on the contrary, the gain of the TR 1 is reduced and the emitter feedback of the TR 3 is increased, so that the gain of the post amplifier stage is also reduced. Since the gain is changed through the resistor 7 without directly changing a feedback resistor 5, the influence of sliding noise can be suppressed. Thus, the S/N can be improved.

Title: Memory access circuit
Inventor: SEKIGUCHI KOJI
IPC: G11C16/06
Filed: 1989-10-17
Abstract: PURPOSE:To prevent erroneous writing by inhibiting the write of data to a ROM after the end of access based on a specific data signal to be sent out of a microcontroller, control signal and access end signal to be sent out of the ROM. CONSTITUTION:Just after a power source is turned on, the output of a NAND circuit 21 is set to '1' regardless of the value of a write signal WR to be sent out of the microcontroller since a charging voltage is low for a capacitor C1 of a power source turn-on detection circuit, and the write to a ROM 50 is inhib ited. When a power supply voltage VCC is lowered less than a prescribed value during normal operation, the output of a comparator CPM is '1', the output of a NOR circuit 17 is '0', the output of the circuit 21 is '1' and the write to the ROM 50 is inhibited. Thus, when a clock or the power supply voltage is instable, the erroneous write can be prevented.

IPC: G11B11/10
Filed: 1990-10-09
Abstract: PURPOSE:To prevent deterioration in the quality of a signal by providing a control means to decrease the magnitude of an initializing magnetic field in modes other than the mode requiring the initializing magnetic field in the recorder so that a magnetic domain not to be lost written already in a recording and reproducing layer is not affected by the initializing magnetic field. CONSTITUTION:A write controller 13 controls an electromagnet controller 12 to allow it to apply demagnetization control to an electromagnet coil 11 in modes other than the initializing write modes. A current flowing to the electromagnet coil 11 is stopped by the control of the electromagnet controller 12 and a magnetic field of an initializing magnet 10 is a weak magnetic field such as 2kOe at the rear side of the disk 1. Thus, magnetic domains not to be lost written in the recording and reproducing layer 1a in modes other than the initializing write modes are not affected by the initializing magnet 10 and the quality of a signal is not deteriorated.

Title: Position data input circuit
Inventor: TANNO TAKAO
IPC: G06F3/038
Filed: 1989-10-17
Abstract: PURPOSE:To quickly, intuitionally and accurately point out a point-out position on a screen by inputting a point-out position data with stick and knob operation. CONSTITUTION:When the operator operates a stick device 1, a position data P1 is fed to a counter circuit 4 and also a touch pulse T1 is outputted to a signal generating circuit 3, then the signal generating circuit 3 outputs a sample pulse S1 to the counter circuit 4. Thus, the counter circuit 4 samples the position data P1 by using the sample pulse S1 and outputs the result. When the operation of the stick device 1 is stopped, the position data P1 inputted finally is latched. On the other hand, when the operator operates a rotary encoder 2, a direction pulse D1 and a rotary pulse R1 are outputted to the counter circuit 4. Thus, since the position data P1 latched in the counter circuit 4 is outputted while being increased or decreased, the point-out position is inputted quickly, intuitionally and accurately.

IPC: G11B5/035
Filed: 1990-10-11
Abstract: PURPOSE:To execute recording reproduction with little deteriotation in image quality to improve the S/N of a system by providing a recording system in which a rectangular wave is used as an FM signal waveform which should be recorded and a reproducing system with a reproducing equalizer which has the reverse characteristic of the frequency characteristic of the recording system. CONSTITUTION:An input signal becomes the FM signal of the rectangular wave by a limmiter 2 and is written on a magnetic tape 6 after being FM modulated by an FM modulator. At the time of reproduction, the input signal is read out by a magnetic head for reproduction 7, is amplified by a reproducing amplifier 9, and the frequency characteristic of the reproducing system is corrected by an FQ compensator 10. The compensator 10 generates the reverse characteristic of the resonance characteristic of a reproducing circuit by the magnetic head 7, a rotary transformer 8 and the reproducing amplifier 9, etc. The output signal of the FQ compensator 10 becomes a signal which only causes a loss to the magnetic recording system compared to the output of the limitter 2. Thus, the recording reproduction with little deterioration of image quality due to a loss in the magnetic recording system is executed even in VTR in which a low carrier wave FM recording with wide deviation is executed.
