Abstract: The present invention reduces the time required for inspecting packets and detecting unauthorized commands. An intrusion prevention device (3) is connected to a communication network (9-1) in which a packet including a command for a device to be controlled is transmitted according to a predetermined rule. An analysis table storage part (34) stores an analysis table comprised of a predetermined number of slots for storing a predetermined number of commands together with time information. An input part (31) extracts the command from the packet detected from the communication network (9-1). A parse part (32) inserts the command into the analysis table. An analysis part (33) analyzes whether or not the plurality of commands stored in the respective slots of the analysis table follow the predetermined rule. A notification part (35) outputs an alarm when an analysis result indicates an abnormality. An output part (36) determines whether to pass or discard the packet according to the analysis result.

Abstract: A semiconductor element capable of adjusting a barrier height ?Bn and performing zero-bias operation and impedance matching with an antenna for improving detection sensitivity of high-frequency RF electric signals, a method of manufacturing the same, and a semiconductor device having the same. In the semiconductor element, a concentration of InGaAs (n-type InGaAs layer) is intentionally set to be high over a range for preventing the “change of the barrier height caused by the bias” described above up to a deep degeneration range. An electron Fermi level (EF) increases from a band edge of InGaAs (n-type InGaAs layer) to a band edge of InP (InP depletion layer).

Abstract: A photodiode that can provide a THz operation with a stable output. A photodiode having a pin-type semiconductor structure includes a semiconductor layer structure and n and p electrodes. The semiconductor layer structure is obtained by sequentially layering an n-type contact layer, a low concentration layer, and a p-type contact layer. The low concentration layer is obtained by layering an electron drift layer, a light absorption layer, and a hole drift layer while being abutted to the n-type contact layer. The n electrode and the p electrode are connected to the n-type contact layer and the p-type contact layer, respectively. During operation, the low concentration layer is depleted.
