Abstract: The present invention provides zinc oxide particles having a large specific surface area, and a zinc oxide composite material, and processes for producing these, and the invention is zinc oxide particles formed by crystal growth into a multi-needle shape and having a larger specific surface area than hexagonal columnar particles; to a zinc oxide composite material comprising the zinc-containing thin film and the zinc oxide particles; to processes for producing the zinc oxide particles and the composite material, and an advantage of the present invention is that a larger specific surface area can be obtained than with hexagonal columnar particles, and a particle film of a specified thickness with fewer grain boundaries can be formed, thereby achieving less reduction in dielectric constant due to grain boundaries.

Abstract: It is an object of the present invention to realize a network system which can quickly detect a virus and tends not to be a new cause of vulnerability. A packet data comparator disclosed by the present invention branches inputted packet data into three branches, and includes an additional pattern matching unit which compares the branched packet data with a part of stored data and performs matching with collation patterns stored in a rewritable storage area, a fixed pattern matching unit which compares the branched packet data with the part of the stored data and performs the matching with a logical operation which has been configured with known collation patterns, a notification packet matching unit which compares the branched packet data with the part of the stored data and finds a notification packet, and an identity detection aggregation unit which aggregates results from the respective matching units.

Abstract: The purpose of the present invention is to realize reduction of power consumption of reconfigurable integrated circuits such as FPGAs by decreasing leakage current in SRAMs. A reconfigurable integrated circuit is provided which includes transistors and comprises a first switch with an input terminal, an output terminal, and a control terminal, a first memory with a memory cell connected to the control terminal of the first switch, a second switch capable of shutting down a power supply line or a ground line of the first memory, and a second memory to control the second switch, wherein a value to open the second switch is written into the second memory when the first switch is not operated, thereby shutting down the power supply line or the ground line of the first memory.
