Title: Variable damping coefficient damper using electric viscous fluid
Inventor: INAZUKA TORU
IPC: F16F9/53
Filed: 1992-05-11
Abstract: PURPOSE:To cancel influence of change in viscosity due to temperature by providing a moving means for movably supporting a counter electrode of a fluid communication hole part wand moving the counter electrode according to change in ambient temperature. CONSTITUTION:A gas refrigerant which is expanded or contracted according to change in ambient temperature is sealed in gas refrigerant sealing chambers 2A and 2B. Positions of pistons 5A and 5B at the rear end of counter electrodes 3A and 3B are regulated by springs 6A and 6B with a predetermined energizing force in the non-projecting direction of the electrode. By applying a desired voltage between the counter electrodes 3A and 3B through a raising voltage changing means 26 on the power source E side, viscosity of an electroviscous fluid flowing through the fluid communication hole 1, a damping coefficient K for absorbing oscillation is changed according to a frequency of a source of oscillation. At this time, corresponding to change in the ambient temperature, the counter electrodes 3A and 3B are selectively moved to the direction of an arrow C or D, and a distance L between them is accurately changed.

Title: Phase locked loop device
Inventor: YOSHINO TADASHI
IPC: H03L7/08
Filed: 1987-05-13
Abstract: PURPOSE:To obtain stable tracking performance by measuring the period of an input signal frequency with the transmitting frequency of a voltage controlled oscillator as a reference clock and controlling the transmitting frequency of the voltage controlled oscillator. CONSTITUTION:The rising of an input signal S1 is detected and a circuit 13 generates a latch pulse S2 and a preset pulse S3 a little later. A circuit 14 is preset to an initial value N1 with the pulse S3, counts the oscillating signal of a VCO5 as a reference clock and is preset to the N1 with the next pulse S3. A latch circuit 15 reads a counting value NT of a latch period by the pulse S2. The value NT as an error signal is hold until the next pulse S2 and the VCO5 is controlled through a D/A converter 10 and an LPF4. By this closed-loop 11, the phases of the signal S1 and the oscillating signal of the VCO5 are locked, and M-divided by a divider 12 and outputted. Thus, even when the frequency ratio of the input signal and a VCO is extremely large, since the gain of the closed-loop 11 is not reduced, a stable tracking to the input signal is executed.

Title: Data sink
Inventor: KENMOCHI TOSHIO
IPC: H04N1/32
Filed: 1985-05-31
Abstract: PURPOSE:To reduce the retraining error by activating the second demodulating part when reception of a data signal is started and activating the first demodulating part if the data signal is not detected within a prescribed time. CONSTITUTION:An NCU 9 is used to switch a telephone line 10 from a telephone set 11 to a MODEM 8 in response to the transmission-side call signal. A signal CED for discrimination of a called station is transmitted, and a signal to which a maximum usable data rate is set is transmitted. This receiver waits for response of the signal DIS; and when the response signal comes, the receiver discriminates what signal the response signal is. Poling reception is started if the signal from the destination is a digital transmission instruction signal DTC or the digital discrimination signal DIS, and training reception is started if the signal is a digital instruction signal DCS, and reception of the response is started if the signal is other than these signals. Thus, the retraining error at the picture signal start is reduced.

Abstract: PURPOSE:To suppress a video and a synchronous level separately by performing the DC fixation of a pedestal position for the limitation of the synchronous level by clamping a white level by a pedestal clamping circuit after clamping the peak of the synchronous level of a TV signal. CONSTITUTION:A chip clamping circuit 1 clamps the synchronous peak of a TV signal stably by a clamping pulse from the 1st synchronous separating circuit 2, and a nonlinear amplifier 3 expands the signal in a synchronous level direction and compresses it in a white level direction to send outputs to circuits 4 and 5.

After the value is suppressed to a prescribed value by a synchronous level limiting circuit 7, the resulting signal is outputted from a distributing amplifying circuit 8 by being distributed. Thus, the operation is stabilized to ITV signals differing in level and distortion condition, and the video level and synchronous level are suppressed to prescribed values independently.
