Filed: 1985-09-27
Abstract: PURPOSE:To manufacture easily a net plate by forming as one body a net plate and a pin by using a resin and forming a recessed part for coupling in the periphery of the mounting pin by utilizing a contraction generated at the time of cooling the resin. CONSTITUTION:As for a composite parts 8, the net plate 8a and the pin part 8b are formed as one body by using the resin. When bringing such parts 8 to resin molding, metallic molds 9a, 9b are used. That is to say, the resin is cast into a recessed part between the metallic molds 9a, 9b, each metallic mold 9a, 9b is separated in the direction as indicated with an arrow respectively and the parts 8 is mold-released and thereafter cooled. In such a case, as for a thick-walled part 8e, since its thickness id thick, its contraction is delayed comparing with both end parts of the pin part 8a and as a result after both end parts of the pin part 8a are solidified, the surface of the thick-walled part 8e contracts toward the inside when it is half solidified. Therefore a recessed part 8f which is called contraction commonly is generated in the periphery of the thick--walled part 8e.

Title: Method for reducing radio-wave reflection in reinforced concrete
Inventor: MIYAZAKI HIROSHI
IPC: H05K9/00
Filed: 1993-08-31
Abstract: PURPOSE:To provide a method for reducing radio-wave reflection at low cost with excellent ghost preventing effect without causing restriction on an outer design nor increasing the weight of an outer-wall panel. CONSTITUTION:A reinforcing bar 2 is partly covered with a ferrite core 1 made of Ni-Zn-, Mn-Zn- or MgZn-based material and embedded in a reinforced concrete. A high-frequency current flows through the reinforcing bar 2 when the radio-wave reaches there, but the ferrite core 1 functions as a resistor against the high-frequency current. Then, the reinforcing bar 2 is put in an isolated state electrically at the part that is covered with the ferrite core 1 so that an interaction between a radio wave and the reinforcing bar 2 is prevented, and thereby ghosts caused by a reflected wave can be prevented.
