Title: Vibration control device for marine vessel
Inventor: UDA SUKEYUKI
IPC: B63B43/00
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To eliminate a part, projecting into the sea, of a vibration control device for preventing vibration of a marine vessel caused by pressure pulsation under the sea generated by the rotation of a propeller. SOLUTION: A bottom part recess 4a is formed at a bottom shell plate 4 around a place directly above a propeller 1, and an outboard side opening part of the recess 4a is covered with a rubber plate (vibration control shell plate), flush with the bottom shell plate 4, so as to form a vibration control chamber 6. High pressure air is constantly supplied to the vibration control chamber 6 from a compressed air delivery device 11 so as to provide the vibration control chamber 6 with cushioning function. A projecting part into the sea can thereby be eliminated from a vibration control device while preventing vibromotive force of the vibration control shell plate from being transmitted to the bottom shell plate 4.

Title: Voltage follower circuit
Inventor: SHINOMIYA KOJI
IPC: H03F3/45
Filed: 1985-11-07
Abstract: PURPOSE:To obtain a voltage follower circuit having high accuracy by using transistors for collector grounding actions and detecting the change of the output potential due to the change of the input potential to always have a new collector potential of the transistor. CONSTITUTION:The base of a transistor (TR)Q6 is connected to the emitter of a TRQ5 and the emitter of the TRQ6 to the collector of the TRQ3 respectively. Then the collector of the TRQ6 is grounded and therefore the emitter potential of the TRQ5 can be transmitted as the emitter potential of the TRQ6. As a result, the degrees of Early's effects are always equal to each other between the TRQ3 and a TRQ4. Thus it is possible to actuate a voltage follower circuit at all times without losing a balanced state of a differential amplifier circuit.

IPC: H04N9/85
Filed: 1985-11-06
Abstract: PURPOSE:To minimize the disturbance to the 2nd signal at reproduction by controlling an output level of a level adjusting circuit to control the level of the low frequency component of the 1st signal thereby minimizing the component at a limiter output stage. CONSTITUTION:An emphasis output is inputted to the 2nd Bessel filter to eliminate the 2nd signal from the output of the 1st filter, the 2nd signal is separated and the 1st subtraction circuit S1 reduces the 2nd filter output from the output of the 1st filter. The output of the 1st subtraction consists of the low-frequency component of the 1st signal and is inputted to a level adjusting circuit 4. The phase of the level adjusting output is delayed in comparison with the phase of the added output and the added output is inputted to a delay circuit 3, where the delay is coincident with the output of the level adjusting circuit. The level adjusting output is subtracted from the delay output whose delay is coincident in the 2nd subtraction circuit S2 in this state. The 2nd subtraction output includes the opposite component of the low-frequency component of the 1st signal and is inputted to the 2nd limiter L2, resulting in that the amplitude is limited and the low-frequency component is minimized.
