Patent TW-509612-B (TW)
Title: Eccentric wrench structure
Inventor: YEN AN-TING
IPC: B25B13/00
Filed: 2002-04-18
Granted: 2002-11-11
Abstract: This invention is related to a wrench structure applying eccentric principle to unidirectional locking or releasing of a bolt. A ratchet wrench usually uses a pawl to engage a series of serration for driving the bolt or a nut in a single direction. In the operating process, the pawl must urge against the series of serration one by onein order to achieve its intended effect. Therefore, the ratchet wrench has the shortcomings of being noisy and having inefficient blind angles. Though such shortcomings of being noisy and having inefficient blind angles are eliminated from a pin spanner, the pin spanner is of a larger size than that of a ratchet wrench for the same specifications, while the torque that is taken by the pin spanner is possibly smaller than that by a ratchet wrench. In this invention, a single pin is provided to jointly support rotation of the socket with two curved sections projecting from an external ring structure, such that the pin is maximized to increase the endurable torque. Therefore, a new unidirectional wrench having a size and capability of ensuring torque similar to what a ratchet wrench has, but is quiet in operation and has no blind angles is produced.

Title: Method and system for hard handoff in a broadcast communication system
Inventor: LEUNG NIKOLAI K N
IPC: H04H20/00
Filed: 2002-10-24
Granted: 2004-06-01
Abstract: A method and system for a handoff in a broadcast communication system is disclosed. A subscriber-assisted handoff is impractical in a broadcast communication system due to e.g., a high signaling load, a difficulty to synchronize the broadcast transmission. On the other hand, the small number of broadcast channels enables the subscriber station to perform the handoff autonomously. While performing a handoff between broadcast transmissions, a disruption of service occurs due to lack of synchronization among the broadcast transmissions. To reduce the service disruption, upon detecting a need for handoff, the lower layers inform the application layer about the forthcoming handoff. The application layer thus may take measures to reduce or prevent the disruption.

Abstract: The purpose of the present invention is to provide two kinds of optimum gate manufacturing process when using high dielectric material film to form one part of the gate insulation film. After a dielectric material film, such as the titanium oxide film 6 (gate insulation film of the internal circuit), with a higher permittivity than that of silicon nitride film is deposited on the substrate 1, a silicon nitride film 7 is deposited on top of the titanium oxide film 6.

Then, silicon nitride film 7 and titanium oxide film 6 are remained in the internal circuit area; and after the silicon nitride film 7 and titanium oxide film 6 on the I/O circuit region are removed, through thermally oxidizing the substrate 1, a silicon oxide film 8 (gate insulation film of the I/O circuit) is formed on the substrate 1 surface of the I/O circuit region.

Granted: 2006-06-01
Abstract: A digital camera and method are disclosed having functions for color balancing of digital images by allowing a user to manually adjust the color balance of a scene or image before capturing the final image. A sensor senses the image and sends it to an image processor for color balancing. While the image is displayed on the display, the user can adjust the color balance in real time by manipulating the user input device, which affects color balance parameters used by the image processor. After completion of color balancing, the user captures a final image using a shutter control. The image processor then applies the adjusted color balance parameters to the captured image. One embodiment adjusts the color balancing on a low resolution image and then applies the final color balance parameters to the captured image. The color balance may be adjusted using a color balance menu displayed on the display.
