Title: Foamed coaxial cable
Inventor: HARA YUICHI
IPC: H01B3/44
Filed: 1994-12-22
Abstract: PURPOSE: To make uniform the dispersion of foaming, eliminate coaguration of foaming bodies with one another, and prevent production of gigantic foaming by covering a conductor with an insulating material consisting of hollow particles made from resin and base resin having a lower melting point than the resin. CONSTITUTION: Hollow particles and base resin are mixed together and heated, and the base resin having a lower melting point is melted so that it is in tight attachment to hollow particle film resin. Thereby an insulating body containing bubbles is formed, with which a conductor is covered. The composition of the insulating body, i.e., the ratio of base resin to hollow particles, is made by weight from 1:1 to 1:4 (degree of foaming 50-80%). Thereby production of gigantic foaming is precluded, the foam diameter is uniform, and foaming bodies are independent of one another with no coaguration, so that the deformation due to heating is reduced, and it is made practicable that the electric characteristics are less likely to vary even with application of a mechanical load.

IPC: G06T15/80
Filed: 1988-12-21
Abstract: PURPOSE:To shorten calculating time by providing plural cross deciders which decide the crosses between an optional light beam and obstacles independently of each other and a cross deciding load scattering part which informs the cross deciders of the light beams and the obstacles to be used for the next decision of crosses. CONSTITUTION:The plural cross deciders 2 decide the crosses independently of each other between the light beam emitted directly from a light source and the obstacles that may possibly shield the light beam.
