Case database storage/retrieval system

Abstract: A case database storage/retrieval system comprises a database for storing as a case contents occurred on an object, a script storage section for storing at least one script which describes a typically conducted series of operation and condition descriptions in time order with regard to the object containing the case within the database, a case storage control section for defining a related link between a new case and a specific operation and situation description in the script relating to the new case in order to relate them, and for storing the new case into the database, and a case retrieval section for retrieving to output a case related by the related link from the database, with respect to a specific operation and situation description designated in the specific script.

Resource reallocation for flow-enforced user traffic

Abstract: In a packet (ATM) network, a source node at the entry of the network is responsive to a connection request from a user terminal for invoking a CAC (call admission control) algorithm to accept or reject the request depending on the amount of resource requested by the user, and allocates a portion of a free bandwidth resource exclusively to the user for the duration of the call according to established contract parameter values. Each node of the network responds to a reallocation request from the user for transmitting a copy of the request to a downstream node to elicit an acceptance message therefrom, and reserving a portion of a pool bandwidth resource and invoking the CAC algorithm to additionally reserve a portion of the free bandwidth resource. The node proceeds to allocate the reserved pool bandwidth to the user in response to the acceptance message indicating that the same amount of the reserved pool bandwidth is available in the downstream node. The allocation of the pool bandwidth is temporary. When a portion of the free bandwidth resource is reserved using the CAC algorithm, this portion is exclusively allocated to the user until the end of the call and the temporarily allocated pool bandwidth is returned to the pool resource for other users.

Red-eye detection/retouch apparatus

Abstract: In a red-eye detection/retouch apparatus, a first area extraction unit receives an image including a red eye and a signal representing a small area including the red eye and designated by a user and extracts a first area including the red eye. A first pixel selection unit detects the reddest pixel from the first area and outputs coordinate values and color information of the pixel. A determination unit determines whether the other red eye is present on the basis of the signal representing the small area and the coordinate values of the reddest pixel. The determination unit outputs an instruction signal for extracting a second area where the other red eye is present upon determining that the other red eye is present. A second area extraction unit receives the instruction signal and extracts the second area from the first area. A second pixel selection unit detects the reddest pixel from the second area and outputs coordinate values and color information of the pixel. An area expansion unit receives the coordinate values and color information of the pixels and the first area, detects a red-eye area by area expansion, and outputs the red-eye area. An image synthesis unit receives the red-eye area and the image including the red eye and outputs an image whose red-eye area has been corrected to a natural pupil color.

Process of mounting tape automated bonded semiconductor chip on printed circuit board through bumps

Abstract: Conductive leads are connected at inner ends thereof to electrodes of a semiconductor chip through a tape automated bonding process, and bumps are formed on the other ends of the conductive leads so as to economically and reliably mount the semiconductor chip on a circuit board through a concurrent reflow.

Method of forming silicon oxide film containing fluorine

Abstract: It is an object of the present invention to provide an excellent silicon oxide film formed at a temperature of 200° C. or less, a method of forming the silicon oxide film, and a selective growing method. According to the present invention, by using a vapor containing alkoxyfluorosilane as a main component, a silicon oxide film containing fluorine is formed at a temperature of 200° C. or less in a reaction chamber having a predetermined temperature and a predetermined pressure. In addition, an organic film such as a photoresist film is used as a mask to selectively form the silicon oxide film. Although the silicon oxide film containing fluorine and formed on the basis of the present invention is formed at a very low temperature of 30° C., this silicon oxide film has a water content smaller than that of a silicon oxide film formed at a temperature of 250° C. in a conventional method. In addition, the film properties of the silicon oxide film according to the present invention are better than those of the silicon oxide film formed in the conventional method. Furthermore, a two-layered aluminum wiring structure can be easily formed by the selective growing method.
