A turbofan engine (10) employs a flow control device (41) that changes an effective exit nozzle area (40) associated with a bypass flow path (B) of the turbofan engine. A spool (14) couples a fan (20) to a generator (52). The turbofan emergency power system includes a controller (50) that communicates with the flow control device (41). Upon sensing an emergency condition, the controller manipulates the flow control device to reduce the effective nozzle exit area (40) of the bypass flow path, which chokes the flow through the bypass flow path thereby increasing the rotational speed of the fan. In this manner, the generator is driven at a higher rotational speed than if the flow through the bypass flow path was not choked, which enables a smaller generator to be utilized.

The “Microcosm Terrestrial and Aquatic Landscape Habitat” is a Main Basin Pond 4 surrounded on three sides by artificial rock, “Miniature Mountains” 3 a, 3 b, 3 c or Natural Looking Imitation Rocks. The fourth, front side has no “Miniature Mountains” or Natural Looking Imitation Rocks to enclose the Main Basin Pond. Instead, here I adhere on a Pane of Glass 2 a to the imitation rock surface using Silicon Sealant 2 b or other sealants 2 c: A pond-aquarium hybrid! The “Miniature Mountains” are higher than the water level in the Main Basin Pond. On the top or sides of the “Miniature Mountains” is an Upper Pool 5. Water in the Main Basin Pond is circulated up to the Upper Pool using a Submersible; Electric, Aquatic, Pump 8. From the Upper Pool, the Water then flows down a Water Course to the Waterfalls and back to the Main Basin Pond to oxygenate the water.

A lower thread ending region detection apparatus prevents problems associated with false stitchings occurring from inability to detect lower thread's exhaustion during sewing operation. The lower thread ending region detection apparatus comprises: light control unit, which contacts a part of lower thread wound on a thread bobbin and activates or inactivates at least one of the functions of emitting light, reflecting light, passing light and blocking light, due to the effect of the physical movement force generated depending on whether the lower thread of the ending region is unwound; light receiving unit, which receives the light transferred out by the light control unit and outputs a detection signal; and control and notification unit, which analyzes the detection signal output from the light receiving unit to determine whether the lower thread has reached the ending region and outputs the result to the user.

The wing attaches to the rod along the axial length of said rod and the rod extends from the base. Each of the individual spool thread holders comprising the multiple spool thread holder, allows receipt of a spool of thread and the wing maintains the spool of thread adjacent the base. The frame is configured for attachment to a quilting machine to allow thread to unspool from each non-rotating spool of thread during operation under substantially equal tension.

Disclosed is a drillship having a vortex suppression block with a recessed flow stabilizing part in a moon pool. The flow stabilizing section is formed so that a bottom of the vortex suppression block that protrudes from a bottom of a hull toward a stern in the moon pool is recessed in an upward direction of the hull to stabilize a flow in the moon pool and reduce a variation in resistance of the drillship. The flow stabilizing section (30) is formed by partly recessing the bottom of the vortex suppression block toward an upper portion of the hull. The drillship having this configuration provides resistance performance improvement and flow stabilization of the drillship.
