摘要:
A filter for a CRT screen according to the invention is constituted such that a compound sheet consisting of a conductive net and a transparent resin film is molded so as to be closely attached to the CRT screen, and also to avoid the occurrence of moire fringes, the mesh of the net is selected at a suitable value such that the ratio of the pitch of the scanning lines of the CRT and the pitch of the wires of the net does not fall near simple integers or the inverse numbers thereof. The filter can shut off the electromagnetic waves, electrostatic charge, ultraviolet rays, etc. which are generated from the CRT, without spoiling the resolution of the CRT and can substantially prevent adverse influences on the human body by the CRT. No moire fringes are produced on the screen. A hard coating treatment and a glare-proofing treatment are further performed, so that an illumination lamps or the like in the room are not reflected from the filter surface. Therefore, the operators can continue their work without fatigue of the eyes and without adverse mental influence based on such fatigue. Further, when the surface of the CRT filter is cleaned or even if a point of pencil or the like accidentally touches the filter surface, no scratching is caused on the surface.

A CRT filter of the present invention consists of a film having a transparent conductive layer and effectively eliminates the static electricity which are generated from the CRT. Further, after the film previously having the transparent conductive layer was continuously manufactured, it can be laminated onto a nonconductive transparent sheet or plate. The transparent conductive film of a stable quality can be cheaply obtained. Thus, the CRT filter having the excellent static electricity eliminating capability and high resolution is manufactured. On the other hand, the CRT filter of the invention has such a shape as to be closely attached onto the front surface of the CRT. Therefore it is also possible to prevent such a phenomenon that the display image in the corner portion of the screen is blurred without deteriorating the resolution. The operator can continue the work without feeling the fatigue of the eyes and the mental pain.
摘要:
An imaging device for capturing an image of an imaging object that is an artificial food mass, in which a light-transmissive microparticle is contained in a base material having a property of blocking infrared light, includes imaging means for capturing the image of the imaging object from one side; and an infrared light source that emits infrared light on the imaging object from the other side of the imaging object. The imaging means includes visible-light removing means for not receiving visible light. The imaging means captures the image of the imaging object while the infrared light source emits the infrared light on the imaging object. The device can accurately count the number of “microparticles not finely crushed or ground” by a computer or the like.

Resin compositions comprising hygroscopic resins of relatively high water absorption rate, including (or coated by, or covered by) ceramics capable of emitting far infrared rays. The resin compositions are useful as materials of devices or receptacles for maintaining freshness of food or water.
