Title: Power cable
Inventor: SATO TOMOTERU
IPC: H01B9/02
Filed: 1993-02-22
Abstract: PURPOSE:To reduce a required cross sectional area of a metal wire shielding layer by filling a space between metal wire shielding layers with semi-conductive mixture mainly composed of thermal plastic material having a melting point lower than that of a sheath. CONSTITUTION:A space between metal wire shielding layers 1 is filled with the semi-conductive mixture 9 mainly composed of thermal plastic material having a melting point lower than that of a sheath 8. The heat generated by the grounding current is radiated more than the conventional one, and the heat generation of the layers 1 by the grounding current is restricted to obtain a power cable, in which a required cross sectional area of the layer 1 is reduced. In this case, as the thermal plastic material, polyethylene and EVA are used, and vinyl mixture is used for the sheath 8. Since the mixture 9 exists without the existence of an air layer in the periphery of the layer 1 at the time of grounding, heat radiation is improved remarkably, and since the mixture 9 is melted to absorb this heat generation, a required cross sectional area of the layer 1 is reduced in comparison with the conventional one.

Title: Optical communication equipment
Inventor: IKEDA TETSUTO
IPC: H04B10/00
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a malfunction caused by the sneaking of an optical signal from a light emitting part to its own light receiving part. SOLUTION: The optical signal transmitted from a light emitting part 12 is received by a light receiving part 11 while sneaking, and an unnecessary reception signal 111 is outputted. Since the reception signal 111 is forcibly made inactive at a sneaking prevention circuit 15 while a transmission signal 112 is active, no signal caused by sneaking is generated in a reception signal 113. Thus, the occurrence of the malfunction caused by the sneaking of the optical signal from the light emitting part to its own light receiving part can be prevented while keeping the simple circuit configuration for performing light emission and light reception at the same modulation frequency as it is.
