There is provided a head-rest of a car sheet which is configured to includes: a skin configured to cover a surface of the head-rest; a foamed material filled in the head-rest covered by the skin; and a stay extending to an outside from the skin in which the foamed material is filled, wherein the head-rest has a gate shape by indenting a center portion of a lower surface of the head-rest, and a groove portion is formed at the indented center portion of the gate shape by making end portions of the skin abut against each other, and members which are softer than the skin are seamed to the respective end portions of the skin which abut against each other in the groove portion.

A low-noise wide band amplifier is realized utilizing a superconductor-insulator-superconductor (SIS) junction, quasiparticle frequency mixers connected in tandem or in cascade, a first quasiparticle mixer performs first frequency mixing with use of a first local signal having a frequency not less than twice a frequency of an input signal to the first quasiparticle mixer, a second quasiparticle mixer performs second frequency mixing with use of a second local signal having a frequency not more than twice a frequency of an input signal to the second quasiparticle mixer, and signal amplification is performed through frequency conversion by extracting, from among a plurality of signals generated with the first and the second frequency mixing, a signal in a frequency band not more than a frequency band of the signal before the first frequency mixing and the second frequency mixing, using a transmission line or a filter.

A foaming die device for forming a headrest is provided, which comprises a lower die having a first protrusion and an upper die having a second protrusion. The lower and upper dies are used for accommodating a trim cover assembly with a headrest stay portion extending outwardly through a stay passage hole formed in the trim cover assembly. The first and second protrusions are adapted to press and turn over a projected area created about the stay hole into the inside of that trim cover assembly. Also, a foaming process for forming the headrest, using this foaming die device, is provided, in which the projected area is turned over by the first and second protrusions into the trim cover assembly when placing the trim cover assembly in the dies. Hence, conventional preliminary steps using cylindrical stick to turn over the projected area into the trim cover assembly are eliminated.
