Patent number: 7900570Abstract: The present disclosure relates to techniques for reducing roll motion experienced by a floating vessel. The disclosure reveals several different techniques for damping roll motion, which may be used alone or in conjunction to stabilize a floating vessel. A typical disclosed embodiment of a roll motion damping device would employ a sponson on each side of the vessel. Each sponson would typically encompass one or more baffles. And a wing keel could be located on the outside of each sponson. When all of these features are used in conjunction, they work synergistically to maximize the resistance to roll experienced by the floating vessel.Type: GrantFiled: January 21, 2009Date of Patent: March 8, 2011Assignee: Zentech, Inc.Inventor: Hin Chiu

Patent number: 4701076Abstract: A terminator assembly is disclosed herein for use in mooring a floating structure to the floor of a body of water. A hawsepipe extends downwardly from adjacent an upper support on the floating structure and is supported by a lower support. Tension members utilized from mooring the floating structure extend downwardly from adjacent the upper support through the hawsepipe and a lower end of the tension member is adapted for connection to the floor of the body of water. A locking device is connected to an upper portion of each tension member for maintaining the tension member in tension by acting upon the upper portion of the hawsepipe to transfer the vertical loads through the hawsepipe to the lower support on the floating structure.Type: GrantFiled: August 1, 1986Date of Patent: October 20, 1987Assignee: Amoco CorporationInventors: Hin Chiu, Johnce E. Hall

Patent number: 3964089Abstract: A junction transistor is provided which is especially adapted for use in an amplifier circuit in which third-order intermodulation distortion is especially low. To this end, an epitaxial junction transistor is made to have a substantially linearly graded concentration of the dominant impurity over at least half of the high resistivity portion of its collector zone.Type: GrantFiled: June 11, 1975Date of Patent: June 15, 1976Assignee: Bell Telephone Laboratories, IncorporatedInventors: Hin-Chiu Poon, Donald Lee Scharfetter
