An analog-digital converter includes: comparators disposed to correspond to analog signals which are converted into digital signals and configured to compare a voltage value of the analog signal, which is converted into the digital signal, with a voltage value of a predetermined reference signal; counters disposed to correspond to the comparators and configured to count a count value at the time point when the comparison process of the corresponding comparator is finished; and a determiner configured to determine a time point when all the comparators finish their comparison processes.

In an antenna device, a first helical part of a first antenna and a second helical part of a second antenna is disposed in a dielectric body on a ground plane. Each helical part is helically wound up in a direction perpendicular to the ground plane and includes a plurality of one-turn portions. Each one-turn portion of the first helical part has a peripheral length of M times a wavelength λ of use, where M is a positive natural number. One of the one-turn portions of the second helical part closest to the ground plane has a peripheral length Ks that is N times the wavelength λ of use, where N is a positive natural number greater than M. One of the one-turn portions of the second helical part farthest away from the ground plane has a peripheral length Ke, and (M·λ)

A helical antenna includes a ground plate, a first helical portion spirally wound perpendicular to the plate, a second helical portion spirally wound perpendicular to the plate and surrounding the first helical portion radially outward of the first helical portion, and a feeder circuit. The circuit includes an oscillator, a divider connected to the oscillator, a first phase shifter connected between a first output terminal of the divider and a feeding point of the first helical portion, and a second phase shifter connected between a second output terminal of the divider and a feeding point of the second helical portion. Length of one turn of the first helical portion is equal to a result of multiplication of a wavelength of oscillation of the oscillator by N. Length of one turn of the second helical portion is equal to a result of multiplication of the wavelength by M (M>N).

The present invention relates to a process for producing an ether compound in a simplified, efficient manner, including the step of reacting a hydroxyl group-containing compound with an epoxy compound in the presence of an oxide of a metal of Group 4 of the Periodic Table on which a sulfate ion is supported, wherein a sum of a diffraction intensity of a (111) crystal lattice plane and a diffraction intensity of a (−111) crystal lattice place of the metal oxide is 2000 cps or larger as measured by subjecting the metal oxide to powder X-ray diffraction analysis.
