Abstract: A sample coil for NMR detection includes a first coil unit and a second coil unit placed with a sample therebetween. In the first coil unit, a first coil and a second coil are formed on a first plane of a first substrate. In the second coil unit, a third coil and a fourth coil are formed on a second plane of a second substrate. Each of the coils is a superconducting coil. When viewed from an x direction orthogonal to the first plane and the second plane, the first coil and the second coil do not intersect the sample, and, similarly, the third coil and the fourth coil do not intersect the sample.

Abstract: An elastic wave device that excites main vibration of an SH mode includes a piezoelectric layer formed from a piezoelectric material, a carrier substrate, and an IDT electrode formed on the piezoelectric layer. When a wavelength of an elastic wave, which is determined by an electrode cycle P of the IDT electrode, is represented by λ, the piezoelectric layer has a thickness of 0.15λ or more and 1.5λ or less. The carrier substrate has an acoustic anisotropy, and is arranged in a crystal orientation that reduces unnecessary vibrations of an SV mode and a vertical L-mode.

Abstract: [Problem] To provide a swing-type speed reducer that has a large crossing angle, and that can be further miniaturized compared to conventional speed reducers.
[Solution] Provided is a swing-type speed reducer 1 comprising: a main body 10; an input shaft 20 that is rotatably held in the main body 10; a precession body 30 that precesses; a swinging body 40 that engages with the precession body 30 and is swung by the precession; and an output shaft 50 that is rotated by the swing of the swinging body 40. In the present invention, a precession annular groove 34 for precession of the precession body 30 and a swinging annular groove 33 for swinging the swinging body 40 are provided on the surface of a spherical portion 31. Thereby, in comparison to a conventional case where the grooves are provided on the inner peripheral surface of a member, the region where the grooves can be machined is increased, and the device can be further miniaturized.
