A lateral semiconductor device includes a semiconductor layer, an insulating layer, and a resistive field plate. The semiconductor layer includes a first semiconductor region and a second semiconductor region at a surface portion, and the second semiconductor region makes a circuit around the first semiconductor region. The insulating layer is formed on a surface of the semiconductor layer and is disposed between the first and second semiconductor regions. The resistive field plate is formed on a surface of the insulating layer. Between the first and second semiconductor regions, a first section and a second section are adjacent to each other along a circumferential direction around the first semiconductor region. The resistive field plate includes first and second resistive field plate sections respectively formed in the first and second sections, and the first and second resistive field plate sections are separated from each other.

A method, an apparatus and a program for detecting spoofed Internet Protocol (IP) traffic directed to a network having a plurality of autonomous systems (AS) is provided. The method comprises receiving an incoming packet through an AS, the incoming packet containing a source IP address and a destination IP address, acquiring a corresponding source and destination IP address prefixes, converting the corresponding source and destination IP address prefixes into a source AS number and a destination AS number, determining if the incoming packet arrived from an unexpected source based upon the corresponding destination IP address prefix and the converted source and destination AS number using an unexpected pair tuple table generated from network routing information and generating an alert indicating that the incoming packet is not allowed to enter the network.

An image capture device includes a viewfinder for viewing a subject. The viewfinder either forms an integral part of the device or is an external member that is attachable to, and removable from, the device. The device includes: an optical system; a generating section for capturing an image of the subject through the optical system and generating image data; a detecting section for detecting the degree of focusing of the subject's image represented by the image data; a display section on which the subject's image is presentable based on the image data; and a controller for accepting a decision to use either the display section or the viewfinder for viewing the subject to shoot. If the controller accepts the decision to use the viewfinder, the display section displays no subject's image, and displays information about the degree of focusing of the subject's image for at least a certain period of time. The information has been obtained based on a result of detection done by the detecting section.

The lead-out side end of a drain wire led out from a shield wire and either a conductor exposed to one end of a ground wire, to the other end of which a ground terminal is connected, or a conductor exposed to one end of a ground wire, to the other end of which a connector receiving terminal is connected, are collectively connected together by crimping by using a U-shape cross-sectioned intermediate crimp terminal formed by a pair of opposed barrels, or connected by twisting them together, or connected through a joint bus bar.

A recording apparatus including a recording head that discharges UV ink onto a recording material and an ultraviolet light irradiation unit that irradiates ultraviolet light to the discharged UV ink so as to harden the UV ink; further includes a failure diagnostic unit that diagnoses a failure condition of the ultraviolet light irradiation unit and a controller that controls operations of the recording head, the ultraviolet light irradiation unit, and the failure diagnostic unit. Further, the controller is so configured as to change the operation mode of the recording apparatus to a failure-state mode when the ultraviolet light irradiation unit has been diagnosed as a failure by the failure diagnostic unit.

A passage block coupling apparatus including a bolt insertion hole 13 and a pin insertion hole 14 formed in an upper-stage passage block 3, a screw hole 15 and a non-screw hole 16 that are formed in a lower-stage passage block 4, a bolt 11 that is inserted into the bolt insertion hole 13, and threaded with the screw hole 15, and a positioning pin 12 that is inserted to the pin insertion hole 14, with its lower end portion being fitted to the non-screw hole 16. A cut-out section 17 is formed near the lower end portion of the positioning pin 12, and a protruding portion 18 to be fitted to the cut-out section 17 is formed on the opening portion of the non-screw hole 16. A tightening force exerted by the bolt 11 and a force exerted by the lower end portion of the positioning pin 12 to press the protruding portion 18 of the non-screw hole 16 upward are balanced with each other so that an evenly fastened state is achieved so that the passage blocks 3 and 4 are coupled with each other.
