The present invention relates to a method for reducing the frictional drag of a ship and to a ship with reduced frictional drag, and its objects include effectively reducing the driving force used during the travel of a ship by decreasing the power required for delivering gas into water as well as to decrease the construction cost for a ship. A negative pressure portion 21 whose pressure becomes lower than the pressure in a gas space during the travel is formed in the water, and bubbles 22 are discharged into the water by introducing gas from the gas space to the negative pressure portion 21 in water.

A method is provided for analyzing the effects of bubbles on skin-friction reduction in a ship cruising in a bubbly flow field. A shear stress decrement &tgr;t produced by a bubble in a flow field is obtained in a high frequency band region, in which a product of a bubble time-constant T and a turbulence frequency &ohgr;L in a flow field is sufficiently greater than 1, based on a resistive force &Dgr;Rv acting on a bubble derived from the bubble movements in a fluid flow direction along a ship surface and in a direction at right angles to a ship wall surface. Assuming that the shear stress a decrement is generated by a decrease in a gas mixing length, an expression for the operative wall constant &kgr;1 for bubbly flow including a parametric bubble diameter db is derived. Based on an expression relating the operative wall constant &kgr;1 and a local friction factor Cf in bubbly flow, and an expression relating the normal wall constant &kgr; in non-bubbly flow and a local friction factor Cf0 in non-bubbly flow, an analytical solution is obtained for a skin-friction ratio Cf/Cf0.

摘要:
A simulation method for imaging of an underwater object is performed by simulating the object with a test panel having several strips of different brightness, and irradiating the test panel with a pulsed laser beam having three primary colors. From the reflected beam pulses, contrast values of the test stripes are computed for reflected pulses of each color in relation to the turbidity and visibility distance. The method may be used in conjunction with an imaging apparatus having a laser generation device which produces three primary colors of three different wavelengths; a laser beam detection device to receive the reflected beam pulses of respective primary colors, to determine intensities of the reflected beam pulses of respective primary colors, and to output three primary color signals to an image monitoring device. The imaging system may also be arranged so that a laser irradiation device, a laser beam detection device and an image monitoring device are all placed underwater in a submersible vessel with appropriate provisions for hydrostatic pressure and unmanned operation.

A latch device on a vehicle tailgate having upper and lower doors comprises an open handle assembly for releasing a lower latch assembly from a lower striker, a key cylinder for releasing an upper latch assembly and an upper striker, a coupling mechanism displaceable between a locked position for disabling an opening operation of the handle assembly and an unlocked position for enabling the opening operation of the handle assembly. The upper latch assembly has a latch and a ratchet. The ratchet is displaceable between an engaging position for engaging with the latch located in a door-closed position and an initial position for making contact with the latch located in a door-open position. The coupling mechanism is displaced to the locked position when the ratchet is in the engaging position and displaced to the unlocked position when the ratchet is in the initial position.
摘要:
A submersible unit having thrusters for changing a diving position based on a total work quantity, which is the sum of a first work quantity and a second work quantity. A proportional controller generates and outputs the first work quantity based on a difference between a position quantity indicating a desired target diving position and a diving position. A network controller uses a neural network data processing system to learn movement characteristics of the submersible unit based on the first work quantity and a diving position sampled over a plurality of times. The network controller generates a second work quantity using control coupling coefficients learned by minimizing an evaluation quantity determined from a difference between the learned movement characteristics and target movement characteristic values.
