Abstract: The present invention intends to improve communication efficiency between two communication apparatuses each engaged in the communication by full duplex communication method by using a surplus band of the one to transmission band of the other. A first bandwidth required by a first communication apparatus (A) at data transmission and a second bandwidth required by a second communication apparatus (B) at data transmission are presumed. Next, the first bandwidth presumed as mentioned is compared to a first bandwidth used which the first communication apparatus (A) currently uses and at the same time, the second bandwidth presumed as mentioned is compared to a second bandwidth used which the second communication apparatus (B) currently uses. The first bandwidth and the second bandwidth are then adjusted, and a third bandwidth which the first communication apparatus (A) uses at data transmission and a fourth bandwidth which the second communication apparatus (B) uses are determined.

Abstract: The invention provides a prepreg peel ply to be laminated on a surface of a composite material prepreg for forming a member having a concaved portion such as an H-shaped member, wherein the prepreg peel ply is peeled off after performing hardening so as to improve the adhesiveness of the surface of the composite material. A prepreg peel ply impregnated with resin having a hardening property substantially equivalent to that of the composite material prepreg is used as the peel ply to be laminated on a surface of the composite material prepreg. Through use of such prepreg peel ply, it becomes possible to apply a continuously formed prepreg material to form members having concaved portions, such as H-shaped members, and to form excellent members without voids.

Abstract: A pattern area that includes a plurality of line patterns with a predetermined spacing therebetween formed on a wafer is imaged, and based on the imaging results, a contrast value of an image of the pattern area is computed, and the computed contrast value is converted into the linewidth of the line pattern based on known conversion information. Therefore, even if the pattern area is imaged using a microscope having a low resolving power, e.g. an image-forming type alignment sensor or the like, without using the SEM, the linewidth of the line pattern can be measured with high precision. Accordingly, linewidth measurement with low cost and high throughput becomes possible.

Abstract: A system and method for database security provides, a database security method that receives an encryption property from an application and receives information relating to a database server. The method then requests security access to a database server using the strongest encryption algorithm server may support. If this request gets turned down, then the method determines the strongest encryption algorithm the server actually supports using the information the database server sent back and calculates the encryption keys. The method then caches the encryption algorithm along with the encryption keys in a persistent storage. For subsequent connections, the method checks the persistent storage first and retrieves the encryption algorithm and encryption keys from the persistent storage if the cache values are available, and sends the cached value to database server. By doing this, the database driver doesn't need to synchronize the encryption algorithm with server and calculate the encryption keys again.
