    摘要: Electronic apparatus includes first and second electronic devices (10, 20), for operation respectively at first and second different temperatures, mounted respectively on first and second substrates (8,18), each of which substrates (8,18) has a circuit pattern (9,19) to which the electronic device (10,20) mounted thereon is electrically connected, the said first substrate (8) being mounted within a working chamber defined within thermal isolation means (2;2′) for maintaining the first electronic device (10) at the said first temperature, the said second substrate (18) being mounted adjacent to, but externally of, the said thermal isolation means (2;2′) so as to enable the second electronic device (20) to be operated at the said second temperature, and there being connecting means (22) passing through a wall portion of the thermal isolation means (2;2′) and providing electrically conductive connections between the respective circuit patterns (9,19) of the first and second substrates (8,18), thereby connecting the first electronic device (10) electrically to the second electronic device (20). In such apparatus use of coaxial cable to interconnect the first and second electronic devices (10,20) can be avoided. Preferably, the first and second substrates (8,18) have respective main faces that are substantially co-planar with one another, and the said connecting means (22) are provided by a sheet-like structure comprising respective electrically-conductive (22b,22d) and electrically insulating films (22a,22c,22e). Such sheet-like connecting means (22) can assist in reducing the rate of heat flow through the said connecting means (22).

    摘要: A microminiature Stirling cycle engine or cooler is formed utilizing semiconductor, planar processing techniques. Such a Stirling cycle thermomechanical transducer has silicon end plates (14, 22) and an intermediate regenerator (50). The end plates (14, 22) are formed with diaphragms (34, 44) and backspaces (32, 42), one end plate (14) forming the expansion end and the opposite end plate (22) forming the compression end, with the regenerator (50) bonded in between. A control circuit apparatus is linked to the diaphragms (34, 44) for controlling the amplitude, phase and frequency of the deflections. The control circuit apparatus is adapted to operate the transducer above 500 Hz and the passages and the workspace, including those within the regenerator (50), expansion space (30) and compression space (40), are sufficiently narrow to provide a characteristic Wolmersley number, which is characteristic of the irreversibilites generated by the oscillating flow of the working fluid in the workspace, below substantially 5 at the operating frequency above 500 Hz. Additionally, the amplitude of the vibrations of the diaphragms (34, 44) vibrations are sufficiently small to provide the working fluid a maximum Mach number below substantially 0.1 at an operating frequency above 500 Hz.
