A position detecting method includes illuminating a grating mark of an object with monochromatic light; forming an interference image on an image pickup device by using .+-. n-th order light (n=1, 2, 3 . . . ) among reflective diffraction light from the grating mark; integrating an image signal produced by the image pickup device within a two-dimensional window of a predetermined size set with respect to the image signal and along one direction in two-dimensional coordinates, whereby a one-dimensional projection integration signal is produced; transforming, through rectangular transformation, the one-dimensional projection integration signal into a spatial frequency region; selecting, on the spatial frequency region and from the one-dimensional projection integration signal, a spatial frequency component which appears in the interference image due to the periodicity of the grating mark; and detecting the position of the grating mark on the basis of the selection.

According to the electronic apparatus and cellular phone of the present invention, in an optical waveguide forming body of a flexible cable, an air layer is provided in a deforming section which experiences bending deformation as a result of the movement of a second body relative to a first body (either a pivoting or sliding movement), and the position of this air layer becomes located on the outer circumferential side of a core when the deforming section undergoes bending deformation. As a result of this, it is possible to ensure sufficient flexibility and to also achieve a sufficient improvement in the folding endurance of the core portion for this optical waveguide forming body to be utilized in practical applications. Moreover, it is possible to suppress light loss and achieve high-speed, large-capacity transmissions even when the optical waveguide forming body of a flexible cable experiences bending deformation due to the relative movement of the second body relative to the first body.

摘要:
It is intended to provide a novel NAD+-independent myo-inositol 2-dehydrogenase which converts myo-inositol into scyllo-inosose in the absence of NAD+; a novel enzyme scyllo-inositol dehydrogenase which stereospecifically reduces scyllo-inosose into scyllo-inositol in the presence of NADH or NADPH; and a novel microorganism which belongs to the genus Acetobacter or Burkholderia and can convert myo-inositol into scyllo-inositol. By using these enzymes or the microorganism, scyllo-inositol is produced. Furthermore, scyllo-inositol is purified by adding boric acid and a metal salt to a liquid mixture containing scyllo-inositol and a neutral saccharide other than scyllo-inositol to form a scyllo-inositol/boric acid complex, separating the complex from the liquid mixture, dissolving the thus separated complex in an acid to give an acidic solution or an acidic suspension and then purifying scyllo-inositol from the acidic solution or the acidic suspension.
