Patent JP-H04259137-A (JP)
Title: Bit synchronization system
Inventor: GUNJI MICHIYO
IPC: H04L7/08
Filed: 1991-02-14
Abstract: PURPOSE:To take synchronization of a transmission signal correctly even when distortion takes place in a transmission signal by taking the synchronization of a reception clock signal again even against bit synchronization deviation in a window after the synchronization of the reception clock signal is established. CONSTITUTION:A window mask circuit 36 decides whether or not a window is valid and when the synchronization is not established, the window is masked to generate a reception clock signal S37 by using an edge detection signal S34. After the establishment of synchronization, the window is made effective and the signal S37 is generated by using window signals S35, S34. Thus, transmission distortion takes place just after the start of transmission while the synchronization is not established, the signal S37 is generated without being affected by the signal S35. On the other hand, even when bit deviation is large before the establishment of synchronization, since the signal S35 is valid after the establishment of synchronization, the phase is not locked as it is without being almost affected to the phase in which the synchronization is taken at first.

IPC: G11C19/08
Filed: 1982-02-15
Abstract: PURPOSE:To improve the reliability against the operating temperature change, by connecting an external resistor matching the resistance temperature coefficient of each conductor and a current temperature coefficient of magnetic bubbles in series with each conductor of bubble memories and driving the memories  with a constant voltage source. CONSTITUTION:In a drive circuit of a function conductor R14 such as magnetic bubble generator and bubble expander, a current correction resistor R23 is connected in series with the conductor R14.

The bubbles, however, have the current temperature coefficient in which the required current is reduced according to the temperature rise of the magnetic substance film, the current correction resistor connected in series corrects the current so as to drive the bubbles at the required optimum current for the bubbles. Thus, the suitable current is applied to each conductor according to the temperature of the magnetic substance film, allowing avoid malfunction.

Title: Alarm transfer system for multiplexing device
Inventor: YAMAMOTO SEIICHI
IPC: H04J3/14
Filed: 1989-01-30
Abstract: PURPOSE:To prevent an alarm representing the disconnection of a satellite communication line from being generated at a low-order multiplexing device by transmitting a 0th-order group signal to the low-order multiplexing device after inserting a frame pattern decided in advance to the 0th-order group signal to the low-order multiplexing device by a highest-order multiplexing device when the satellite communication line is disconnected. CONSTITUTION:When no alarm is detected at an alarm supervisory part 2 and also, S bit='0' is detected by an S bit supervisory part 3 and also, DNR bit='0' is detected by a DNR bit supervisory part, it is judged that the satellite communication line is set at a disconnected state. Therefore, after the 0th-erder group signal is set at '0' by a 1st-order multiplexer(1.5MMUX) 7 and the frame pattern generated at a frame pattern generating part 5 and decided in advance is inserted to the 0th-order group signal, the 0th-order group signal is transmitted to 0th-order group multiplexers(64kMUX) 8-1 and 8-2. And the 64kMUXs 8-1 and 8-2 transmit reception data '1' and a control signal off, and transfer the fact that the satellite communication line cannot be used. In such a way, the alarm when the satellite communication line is disconnected can be prevented from being issued.

Title: Amplifier
Inventor: SONEHARA SOUJI
IPC: H03F3/45
Filed: 1980-02-25
Abstract: PURPOSE: To suppress the DC drift at the output terminal easily, by providing a DC feedback amplifying circuit in the DC amplifier where the first stage is constituted with the differential amplifier and by controlling the constant-current source by the output of this circuit.  
     CONSTITUTION: DC feedback amplifying circuit S which amplifies the ultralow frequency region and the DC region of the output signal is provided in the DC amplifier where the first-stage differential amplifier is constituted with transistors (TR) Qa and Qb and the constant-current source and the output stage are constituted with TRQd and TRQc respectively. When a positive DC voltage appears at output terminal OUT, the output terminal voltage of circuit S drops with the time constant of capacitor Ca and resistance Rc to raise the collector current of TRQd and lower currents of TRs Qa and Qb and lower the collector potential of TRQa, and the bias of TRQc is made shallow. Consequently, the current of TRQc is lowered, and the potential at the output terminal is moved in the negative direction, and the positive voltage is cancelled. When a negative DC voltage appears at the output terminal, the DC potential is held at zero by the reverse operation. Since resistance Rc can be made large, time constant ReCa is made large sufficiently even if Ca is made small, and the DC drift is suppressed easily.

IPC: H02K37/00
Filed: 1978-02-27
Abstract: PURPOSE: To raise efficiency by reducing fluid loss and solid loss by regulating the rotating angle of one step to less than 360°/number of magnetic poles.  
     CONSTITUTION: In a step motor consisting of the permanent magnet rotor 301, the fixers 302 and 303, and the excited coil 304, arrangement is made in such a way that the rotating angle of one step is less than 360°/number of magnetic poles and also the concave poles 305 to 308 provided on the inside circumference of the fixers are almost symmetrical with the magnetic pole 309, the rotor axle 311, and magnetic pole 310. Thus, 90° rotation at one step and also one rotation at 4 steps are made possible. For this reason, since the rotating angle becomes 90°, the half of 180° of conventional one, the kinetic energy required for rotation also becomes approx. half. Thus, assuming the moment of inertia to be the same, the angular velocity is reduced to approx. 0.7 times and thus the fluid loss proportional to the 2 power of the angular and also the solid loss proportional to the rotating angle can be reduced to approx. half.

Title: Bias circuit
Inventor: ISHII JIYUN
IPC: H03F3/213
Filed: 1978-02-27
Abstract: PURPOSE:To prevent the leak of the input signal from the bias line by using the SEPP emitter follower circuit to the bias power source and also to decrease the number of the capacitor to be suited for the integration. CONSTITUTION:The 1st reference voltage V1 features as V1 = VBE + VCC/2 with the forward voltage of the diode set to VBE. As voltage follower G is connected to V1, V1 = V2 is obtained. Accordingly, bias voltage Vref drawn out from the SEPP emitter follower becomes as Vref1 = Vref2 = V2 - VBE = VCC/2, obtaining just the half value of power voltage VCC. As output resistance ROUT is extremely low for the SEPP emitter follower, the leak of the input signal of amplifier A1 to the bias line receives the sufficient attenuation of ROUT/RB1. As a result, the isolation can be improved extremely for the input signal.
