Abstract:
In a network surveillance unit, a video input unit inputs image information output from a video output device such as a camera or a switcher. A coded image storage unit codes and accumulates the image information. An alarm management unit detects the presence or absence of alarm generation from an alarm generating device, and stores the alarm information. A communication unit receives a request from a display terminal through a network, and transmits the coded image accumulated in the coded image storage unit or the alarm information accumulated in the alarm management unit according to the request.
Abstract:
A semiconductor device is fabricated by introducing an impurity element into a Si substrate by an ion implantation process with an energy set such that the depth of a junction formed in the Si substrate by the impurity element is less than about 50 nm, and then annealing the substrate, wherein the method further includes a step of removing an oxide film from a surface of the Si substrate before the step of ion implantation process.
Abstract:
A jig for a cross hatching test which is rectangular in shape and is used for ruling straight lines intersecting each other at a predetermined angle on a rectangular test plate, including (a) a first straight line passing on the surface of the jig with an angle, for adjusting the left longer side of the test plate to draw a straight line on the test plate with the right longer side of the jig; (b) a second straight line orthogonal to the first straight line, for adjusting the lower shorter side of the test plate; (c) a third straight line with the predetermined angle to the left longer side of the jig, for adjusting the drawn straight line to draw another straight line with the left longer side of the jib with the predetermined angle to the previously drawn straight line; and (d) an opening interposed in the middle of the first straight line, for adjusting the left longer side of the plate to the first straight line to draw the straight line on the test plate with the right longer side of the jig.
Abstract:
A plastic film according to the present invention includes a first outer layer made of a polyester elastomer; a second outer layer containing a high-density polyethylene; a first intermediate layer arranged between the first outer layer and the second outer layer and containing a linear low-density polyethylene as a main component; and a second intermediate layer arranged between the first outer layer and the first intermediate layer and containing a polymer of an α-olefin and an unsaturated carboxylic acid or an anhydride monomer of an unsaturated carboxylic acid as a main component. The plastic film can be produced by a co-extrusion method.
