Title: Shield of electromagnetic wave and the like
Inventor: YOSHIE KATSUHIRO
IPC: H05K9/00
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To reduce to the level not affecting human body by discharging negative static electricity form a shield consisting mainly of silicone and compensating positive static electricity when it shields electromagnetic wave caused by the components. SOLUTION: A shield S is placed in front of a CRT of a TV receiver, etc. Since a CRT emits cathode ray, positive static electricity reaching 20 kV or more from the vicinity of the CRT is discharged and electromagnetic wave is simultaneously discharged. By placing a filter l, the static electricity is shielded. So without reaching the level causing adverse effects to a human body apart for ca. 1 m or more, it is shielded by the filter 1. In the case a filter is placed in the vicinity of the CRT in this manner, electromagnetic wave can be not cancelled due to high magnitude and so it is desirable to place a magnetic thin film 4 including magnet on the edge of the filter 1. By placing a filter 1 to the thin film 4, electromagnetic wave is absorbed in the thin film 4, which is annular, the energy of the electromagnetic wave is short-circuited, consumed and shielded.

Title: Coated optical fiber tape
Inventor: HOSOYA TOSHIFUMI
IPC: G02B6/44
Filed: 1988-10-28
Abstract: PURPOSE:To reduce the change of the secular change transmission loss of an optical fiber by composing a tape coating of an ultraviolet radiation curing resin to which a silica micropowder is added. CONSTITUTION:A tape coating 6 executed to the outer circumference of an aggregate in a coated optical fiber tape 10 is composed of the ultraviolet radiation curing resin to which a silica micropowder 7 is added. When the grain diameter of the added silica powder 7 is too large, an adverse effect is generated to the strength of the resin, and when it is too small, the problem such as the increase of a viscosity is generated. When the added quantity of the silica power 7 is too large, the curability of the resin is made bad, and when it is too small, a sufficient adding effect cannot be obtained. Thus, due to an expansion stress applied to the tape coating layer 6, the deterioration of the secular change transmission characteristic generated to the optical fiber can be reduced.
