Title: Optical reception circuit
Inventor: SAKURA NARIYUKI
IPC: H04B10/2507
Filed: 1990-07-03
Abstract: PURPOSE:To output a signal in response to the quantity of comparison by shifting a level of a noninverting signal and an inverting signal so as to cause a voltage equivalent to the signal amplitude and comparing both the signals at a comparator. CONSTITUTION:A photodiode 10 receiving an optical signal E outputs a reception signal IIN. An amplifier 12 outputs a noninverting reception signal VO+VP and an inverting reception signal V.-V, in response to the signal IINNI respectively, where VO is a DC voltage component and VP is a signal voltage component (signal amplitude). A peak level detection circuit 18 receiving the supply of the noninverting and inverting reception signals output a peak signal Vi of the voltage of both the signals, and a voltage-current conversion circuit 28 receiving the signal Vi outputs a noninverting peak signal I+ and an inverting peak signal I- in response to the signal voltage Vi. Thus, the level of the noninverting signal and the inverting signal is shifted at a comparator 34 so that a voltage equivalent to the signal amplitude VP is produced by the noninverting signal having the voltage V+ and the inverting signal having the voltage V-. Thus, the noninverting signal and the inverting signal are compared by the comparator 34 independently of the amplitude VP of the signal.

Title: Frequency multiplier
Inventor: MAAKU II RATSUSERU
IPC: H03B19/16
Filed: 1992-07-01
Abstract: PURPOSE: To provide an output signal which hardly has phase noise in a supplied input signal by providing a detector outputting an intermediate control signal, a temperature compensation circuit outputting a reference signal and a gain compensation circuit containing a differential amplifier. CONSTITUTION: The detector 20 outputs the intermediate control signal and the reference signal showing the peripheral temperature of an amplifier 10 is given from the temperature compensation circuit 26 to the second input of the differential amplifier 24. A control signal being the output of the amplifier 24 is changed in accordance with the change of the intermediate control signal which sequentially changes attenuation quantity obtained in the variable attenuator 16. When a signal level inputted to the amplifier 10 increases, a gain control loop 28 gives the control signal to an attenuator 16 and obtains larger attenuation. When the input signal level to the amplifier 10 reduces, the loop 28 gives the control signal to the attenuator 16 and attenuation which the attenuator 16 gives becomes small. The output signal from the amplifier 10 has the almost constant signal level.  Phase noise does not exist in the output signal and the constant signal level is kept.

Filed: 1980-12-10
Abstract: PURPOSE: To damp the vibration generated from a water-turbine generator by providing the upper portion at upstream side of the generator with a flooding gate and the upper portion at the downstream side with a draining gage.  
     CONSTITUTION: A cavity 14 is flooded and a main gate is submerged by raising a flooding gate 18 to open a flooding port 17 and by lowering a draining gate 21 to close a draining port 20. On the operation of a water-turbine generator 6 by raising a water-turbine closing gate 11 to open a suction port, the vibration thereby is damped by the water flooded in the cacity 14. The opening of the draining port 20 by raising the gate 21 allows the tiding-over from this condition. Even at this tiding-over, the generator 6 can be operated at a fixed position. For repair and maintenance of the generator 6 or each gate such as 5, 11, 18, 21, etc., the gate 18 is lowered at first to close the flooding port 17 and the draining port 20 is opened by raising the gate 21 to drain the water within the cavity 14.

Title: Redundant binary/binary conversion circuit including rounding processing
Inventor: NOMURA MASAHIRO
IPC: G06F7/49
Filed: 1992-07-02
Abstract: PURPOSE:To provide a redundant binary/binary conversion circuit including a rounding processing only by the addition of a few circuits and the increase of a few delay to the redundant binary/binary conversion circuit. CONSTITUTION:An addition necessary for the rounding processing is operated based on a redundant numerical expression by a redundant binary adder 1 for the rounding processing. The transmission of a carry can be limited by the addition operated based on the redundant numerical expression, so that a high parallel property can be realized without necessitating a large-scaled carry preparing circuit indispensable to a binary high speed parallel adder. Then, the redundant binary expression is converted into a binary by a redundant binary/binary conversion circuit 2, and the number of the digits necessary for the rounding processing is limited by a number of digit limiting circuit 3 for the rounding processing based on the binary expression. The characteristic of the round-down of the digits of the redundant numerical expression is different from that of the binary due to the redundancy, and then the round-down of the digits of the redundant numerical expression is operated after the redundant numerical expression is converted into the binary.

IPC: G11B15/02
Filed: 1982-10-05
Abstract: PURPOSE:To detect stably program searching even when a long-playing tape is used, by providing a reel rotation sensor, starting to count after a constant interval of time from detecting a no-signal of a tape, and stopping the tape when a prescribed number of pulses is counted from the rotation sensor of a reel which is taken up. CONSTITUTION:When rapid traverse of a tape is started, a no-signal part is detected by a no-signal detecting circuit 6. In this case, a no-load running part of T1 is made open for an optional time. Time of this T1 is operated to compensate a difference of the number of pulses contained in the no-signal part. Simultaneously with said operation, a pulse is detected from a reel whose tape is taken up, through reel rotation sensors 7A, 7B and a sensor selecting circuit 8, it is counted by a prescribed number by a counter 9, a timing pulse is outputted, and the tape is stopped through a stop signal outputting circuit 10. As a matter of fact, the faster the tape becomes, the earlier the stop signal is outputted, but even when the stop signal is outputted, the tape itself is braked and a distance to the stop is made long, therefore, it makes a position more stable.
