A magnet for a dynamo-electric machine has a plurality of magnetic poles disposed substantially in a circular shape and opposite a plurality of teeth disposed substantially in a circular shape, the magnetic poles and teeth separated by a gap in an axial direction of a revolving shaft. A plurality of inter-pole sections extend circumferentially between adjacent magnetic poles out of the plurality of magnetic poles. The inter-pole sections have tooth-opposed surfaces that are recessed relative to the surfaces of the magnetic poles opposite the teeth in the direction of the revolving shaft. The plurality of magnetic poles and the plurality of inter-pole sections are integrally formed.

A relative position detection device is designed with multiple Hall Effect sensors. In one embodiment, the multiple Hall Effect sensors comprise two different types of Hall Effect sensors. The two different types can be linear and digital. The output of the sensors is used to determine the position an accelerator control, such as a twist grip, and to control an engine or motor in accordance with the operator demand evidenced by the position of the accelerator control. A magnet member is configured to extend the useable region of flux density.

A diffractive optical element having plural diffraction grating surfaces accumulated, wherein a pair of diffraction grating surfaces are positioned so that a protrusion and/or a recess formed on an outside of one diffraction grating surface engages with a recess and/or a protrusion formed on an outside of the other diffraction grating surface, and wherein the pair of diffraction grating surfaces are defined on materials having different refractive indices and different dispersions and being formed into a kinoform, or a shape and a height of blazed or binary, close to it, such that a largest optical path difference to be applied to light rays passing through the diffraction grating surfaces with respect to plural wavelengths becomes equal to a multiple, by an integral number, of the wavelength.

Provided are an optical element and a method of producing an optical element in which sufficient adhesion with an upper layer can be secured without damaging spectral characteristics. The production method includes the step of forming a first structural body in which a space part and a structural part are alternately and repeatedly arranged, the step of forming an etching stopper layer on an upper part of the structural part, and the step of forming a second structural body on the etching stopper layer by etching.
