Title: Method for copy recording in complex recorder
Inventor: LEE YONG SEOK
IPC: H04N5/92
Filed: 2005-12-07
Abstract: A copy recording method in a complex recorder is provided to prevent an unnecessary special playback image from being recorded on a copy medium even when a user does not perform a temporary recording stopping operation. A warning message, which informs a user that a copy recording mode is currently executed, is output when special playback is selected in the copy recording mode of a complex recorder(S205). When the special playback is selected again after the warning message is output(S207), an operation of temporarily stopping recording on a copy medium is automatically carried out(S209). The original medium is played according to the re-selected special playback. When the original medium is returned to normal playback, recording on the copy medium is automatically performed.

Title: Method and device for excluding entry of debris into an outer seal of shaft passing through the hull of a maritime vessel
Inventor: ESKOLA LAURI
IPC: F16J15/16
Filed: 2003-09-24
Abstract: The invention relates to a method and device for excluding the entry of debris into the outer seal of the sealing system of a shaft passing through the hull of a maritime vessel to the exterior side thereof. The outer seals of propeller shafts are conventionally implemented using a mechanical sliding ring seal or an elastic lip seal. When navigating in shallow waters, the wear of the outer seal of the propeller shaft is caused by solid particulate matter floating in the water, whereby the wear rate of the seal under these conditions may be intolerably fast. According to the invention, a flushing flow of filtered water is passed from an internal water source of the vessel to the immediate vicinity of the outer seal. Advantageously, this takes place via a nozzle ring adapted about the shaft. When necessary, the flushing water may also be heated and, the positive head thus applied externally about the seal may be additionally utilized to counteract a possible oil leakage from the bearings of the shaft to the environment.

Larger particles of solid waste are exposed to air in the upper chamber thereby allowing aerobic biological agents to process the solid waste. In use, the filter allows the liquid portion of wastewater to pass from an upper chamber of the treatment tank into a lower chamber. The solid waste particles are then consumed by an aerobic bacteria in the upper chamber.

Title: Decoupling technique for optical disk drive optical pickup units
Inventor: HAYNER DAVID A
IPC: G11B/
Filed: 2004-06-18
Abstract: A low-cost technique to improve the performance of optical disk drives is presented. An algorithm is used to decouple electro-mechanical actuators thus compensating for inaccuracies in the control of the actuators (308, 310). A similar method can be used to decouple the position sensors (316). Prior art methods treated cross- coupling between focus, tracking and sled control loops as noise and therefore increased the bandwidth of the system, also increasing the cost of the optical disk drive. The present disclosure actively decouples the control loops using a software algorithm to provide better performing optical disk drives. The cross-coupling effects are measured, a decoupling matrix is determined, and the output of the control laws is modified so as to decouple the actuators.
