A configuration of an NMR apparatus is provided. In the NMR apparatus, a magnetic field space of higher uniformity is generated by split superconducting magnets. At the same time, it is provided with a cryo probe excellent in cooling capability and sensitivity between two superconducting solenoid coils constructed in very close proximity to each other. For this purpose, a probe coil provided between the two superconducting solenoid coils is so constructed that the following is implemented: a certain distance is ensured between a substrate with a coil formed thereon and another, and the substrates and spacer substrates for cooling are alternately laminated. The spacer substrates are cooled by a cold head of sapphire. When the probe coil is inserted in the same direction as a sample tube (direction perpendicular to the static magnetic field), the spacer substrates cannot be coupled directly by the cold head of sapphire. Therefore, they are cooled through a fixed substrate for thermal conduction of sapphire coupled with the cold head.

A method for designing a semiconductor device having a plurality of logic elements provided with a plurality of power supplies. First, a power supply type name is given to each power supply in accordance with the purpose of the power supply in each logic element. Each logic element is associated with the power supply type name of the power supply that is to be provided to the logic element. A power supply group is formed for each power supply. Specific information of each power supply group associating the power supply type name with supplied voltage is generated. Then, the power supply provided to each logic element is determined by allocating the power supply group to the logic element. The method simplifies designing the layout of a semiconductor device operated by multiple power supplies.
