Title: Rolling reduction device for floating marine structure
Inventor: TSURUOKA MASATAKA
IPC: B63B35/44
Filed: 1985-03-01
Abstract: PURPOSE:To reduce rolling, by forming jet flow along a surface of a submerged part of a floating marine structure by means of jet nozzles to thereby change two-dimensional separation bubbles due to the rolling into three-dimensional vertical vortex and generate a lift. CONSTITUTION:A submerged part 2 of a floating marine structure of a double- barrel semisubmergible type is provided with jet nozzles 6 to form jet flow 7 along the longitudinal direction of the submerged part 2. When rolling is generated by the influence of wave or the like, two-dimensional separation bubbles are generated at each of ridge portions 5 of the submerged part 2. However, the two-dimensional separation bubbles are swept away by the jet flow 7 injected from the jet nozzles 6, and are changed into three-dimensional vertical vortex 8. The vertical vortex 8 generates a lift against each of the ridge portions 5 to function as a rolling damping moment. Thus, the rolling of the marine structure may be effectively reduced.

Filed: 1990-02-22
Abstract: PURPOSE:To improve the yield of the constant voltage circuit by forming the sum of the threshold voltage of the 1st and 2nd transistors (TRs) selected by the 1st switching means. CONSTITUTION:It is supposed that the state of binary control inputs ADJ1,ADJ 2=1, 1 is considered. In this case, '1' and '0' respectively show VDD and VSS levels. Since a TR 101 is ON and a TR 102 is OFF, a current flowing route goes TR 101 TR 103 constant current source 106 and the consideration of the TRs 102, 104 is made unnecessary. Since the gate and drain of the TR 103 are connected to each other, the TR 103 is driven in a saturated area to act as a diode, and when a conductance factor is high, a fixed voltage based upon the VDD is generated at the time of allowing a fixed current to flow. Consequent ly, an oscillation circuit can stably be driven and the yield can be improved.
