A radiation type oscillator is configured by a radiation type oscillator substrate S1 equipped with a microwave transistor 1 for generating negative resistance by short-duration operation and a resonant cavity structure, a high-frequency pulse signal of an oscillation frequency/frequency bandwidth determined based on negative resistance produced by the short-duration operation of the microwave transistor 1 and the resonant cavity structure is generated as a transmitted RF signal and simultaneously radiated into space, and the radiation type oscillator is caused to perform oscillating operation when a received RF signal arriving from an external wireless communication device enters the radiation type oscillator, whereby a received data signal is established based on acquisition of an IF signal owing to mixing by the radiation type oscillator itself.

A head-accommodating area is delimited by the hollow partition between the bottom of the first inner enclosure wall and the ceiling of the second inner enclosure wall both facing each other, and a plurality of SQUID sensors are arranged in the upper closed space, encircling the head-accommodating area. The SQUID sensors are cooled by the liquid helium contained in the upper closed space whereas the first enclosure is cooled by the circulating helium gas from a closed-cycle helium refrigerator. An adiabatic expansion compartment may be placed in the upper closed space. The adiabatic expansion compartment is supplied with cooled helium gas, which is converted into liquid helium by adiabatic expansion, and the so converted liquid helium is led into the liquid helium bath in the form of drops to make up for the consumption of liquid helium during operation. Otherwise, the adiabatic expansion compartment is connected to the SQUID magnetic sensors to indirectly cool the sensors by the thermal conduction body.

摘要： A lower resist film, which is made of PMMA for EB exposure and has a thickness of about 200 nm, is applied onto a substrate, and then an upper resist film to be exposed to i-rays is applied on the lower resist film. Thereafter, a mixed layer, in which the upper and lower resist films are mixed, is formed in the interface between the upper and lower resist films. Next, the upper resist film, except for the head-forming region thereof, is exposed to i-rays and developed, thereby forming an upper-layer opening. And then the mixed layer and a leg-forming region of the lower resist film are exposed to EB and developed, thereby forming a lower-layer opening having an upper part like a taper progressively expanding upward.

摘要： It is possible to improve the negative resistance characteristic that can be expected when an SNS (superconductor-normal conductor-superconductor) structure is used as a structure unit for series connection. On the top of a first superconducting electrode, a second superconducting electrode is superimposed so as to sandwich an insulation film between the first and second superconducting electrodes, with parts of cross sections of the second superconducting electrode and insulation film placed on the top. A normal superconducting line electrically connects the first and second superconducting electrodes passing along the cross section of the insulation film, thereby constituting a structure unit having a single weak link. A plurality of such structure units connected in series are prepared. At the both ends of the series the first or second superconducting electrode is an element connected to a leading line. The structure units are arranged so that the cross sections of the insulation films along which the normal conducting line passes are arranged in the sale direction.

摘要： The present invention provides a low-noise MEG apparatus of high sensitivity. A MEG apparatus using a magnetic shield of high critical temperature superconductor is set on the floor of a building via mechanical vibration suppressor supports to prevent appearance of noise signals. Also, the apparatus is equipped with means for preventing any relative displacement between the SQUID magnetic sensors and the magnetic shield of high critical temperature superconductor, thereby not letting an inevitable mechanical vibration of least strength produce any variable components of the trapped static magnetic field, which the SQUID magnetic sensors could be sensitive to.
