摘要： PROBLEM TO BE SOLVED: To provide a catamaran having less wave-making resistance and high energy efficiency even if its hull shape is thick or an inter-hull space is narrow, especially applicable to a twin-bow vessel designed to cruise on the inland sea such as the Seto Inland Sea which generates small waves (back wash) at cruising so as not to give damage to a marine facility for cultivating oisters etc., or which can transport many passengers efficiently.
SOLUTION: The catamaran has a pair of hulls under the upper vessel body coupled with each other by a cross-deck, wherein the hulls are arranged so that the space between their center planes C.L is narrowed from the top toward the vessel bottom when viewed from the nose of the vessel.

摘要翻译：要解决的问题：即使其船体形状较厚或船体间隙窄，也能提供具有较小的抗波浪性和高能量效率的双体船，特别适用于设计用于巡航的双弓船诸如濑户内海等内陆海域，在巡航时产生小浪（背洗），以免对海洋设施造成损害，或者可以有效地运输许多乘客。解决方案：双体船在上船体之下具有一对船体，其通过交叉甲板彼此联接，其中船体被布置成使得它们的中心平面CL之间的空间从顶部朝向船舶底部变窄当从船的鼻子观察时。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a propeller jet flow generating device that effectively achieve an improvement of a thrust efficiency by preventing generation of cavitations by making a propeller wake distribution uniform, and an improvement of the thrust efficiency by reducing a swirl flow downstream of a propeller by forming an inverted flow upstream of the propeller. SOLUTION: A propeller jet flow generating device 100 includes a pump 5 serving as a sea water intake/eject means for taking sea water SW from an intake port 2 provided to a ship bottom 1 therein and ejecting the taken sea water SW toward the rear of a ship body from an ejection port 4 provided to a stern 3. The device generates a jet flow 7 toward a propeller 6 attached on a rearward part of the ship body relative to the ejection port 4. As the sea water intake/eject means, a cooling sea water intake means of a ship equipment 8 is used. In addition, at least one of an ejecting amount and an ejecting direction of the sea water SW being ejected from the ejection port 4 is changeable. In addition, the inverted flow is formed upstream of the propeller 6 by the generated jet flow 7. COPYRIGHT: (C)2011,JPO&INPIT
摘要翻译：要解决的问题：提供一种螺旋桨喷流产生装置，其通过使推进器尾流分布均匀而防止产生气穴，有效地提高推力效率，并且通过减小涡流来提高推力效率在螺旋桨的下游形成螺旋桨上游的反向流。解决方案：螺旋桨喷流产生装置100包括用作从设置在船底1的进气口2中取出海水SW的海水进水/喷射装置的泵5，并将取出的海水SW朝向从设置在船尾3的喷出口4的船体的后部。该装置朝着相对于喷射口4安装在船体的后部的螺旋桨6产生喷射流7.作为海水摄入/ 喷出装置，使用船舶设备8的冷却海水吸入装置。此外，从排出口4排出的海水SW的喷射量和排出方向中的至少一个是可以改变的。另外，通过产生的喷流7在螺旋桨6的上游形成倒流。（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a pusher/barge unitary hull capable of attaining a substantial energy saving through improvement of a recovering action during a single cruising of the pusher, releasing of a restriction on its speed and improvement of a propulsion performance under a connected state of the pusher and the barge.
SOLUTION: This hull has a pusher 10 and a barge 20 removably formed into a unitary device. A connecting cavity 11 is formed at the central part of a hull head of the pusher 10 to make a three-barrel type hull. A connecting protrusion 21 inserted into the connecting cavity 11 and assembled thereto is formed, a hull bottom part of the pusher 10 is formed into a buttock flow type while it is applied as a slant part 12 cut and raised upwardly in a slant manner toward e hull tail side. Both side surfaces are applied as parallel straight line surfaces 2 over an entire range from a part except the hull head of the barge 20 to the pusher 10. The hull tail of the pusher 10 is provided with a single shaft type, double-shaft type or multi-shaft type propulsion device 13.
