    • The present invention provides a counterweight and a counterweight-recycling method capable of having excellent workability, capable of reducing manufacturing costs, and capable of achieving environmental conservation. A metal portion contained in slag produced in an iron making process or in residue in a waste treatment furnace is used as a weight material of a counterweight (10). A method of recycling the counterweight (10) includes a removing step of removing an outer shell (15) of a used counterweight (10) that has used a magnetic metal portion as a weight material, a crushing/cutting step of crushing a filler containing the metal portion of the counterweight (10) from which the outer shell (15) has been removed and cutting a combined state between the metal portion and the other filler portion, and a separating step of separating processed products obtained in the crushing/cutting step into high-specific-gravity substances composed chiefly of the metal portion and into other low-specific-gravity substances, in which the high-specific-gravity substances are used as weight materials of a counterweight to be newly manufactured.

    • The invention provides a composite high frequency component constituting a part of a microwave circuit having plural signal paths corresponding to their respective frequencies, comprising: a diplexer for coupling transmitting signals from the plural signal paths for transmission and distributing receiving signals into said plural signal paths for reception; plural high frequency switches for separating the plural signal paths into a transmission section and a reception section, respectively; plural filters introduced in the signal paths; said diplexer, said high frequency switch, and said filters being integrated into a ceramic multi-layer substrate formed by lamination of plural ceramic sheet layers. According to the above described composite high frequency component, the diplexer, the high frequency switches, and the filters which constitute the composite high frequency component are integrated into the ceramic multi-layer substrate formed by lamination of plural ceramic sheet layers. Thus, the matching and adjustment between the diplexer and the high frequency switches can be easily performed. It is unnecessary to provide a matching circuit for matching and adjusting the diplexer and the high frequency switches, and moreover, the high frequency switches and the filters.
