    摘要: In a method for winding a toroidal coil, a winding of a first layer is made by means of repeating the following three steps. At a first step, one end of a wire is inserted into a central aperture of a core from one side thereof to extend the wire along an axial direction of the core; the other end of the wire is abutted to one surface of the core such that the other end is radially extended; and a tension is applied to the wire and the core with the other end of the wire is then turned in a diametrical direction of the core perpendicular to the radial direction. At a second step, the one end of the wire is inserted into the central aperture of the core towards the other side; and the tension is applied to the wire and the core is then rotated at a desired angle in one direction on a central axis of the core. At a third step, the core is grasped again by core turning means to turn the core in the same direction; the one end of the wire is inserted into the central aperture of the core towards the one side thereof, the one end being extended and the tension being applied to the wire, and then the core is rotated using the core turning means to shift it back at the desired angle in the other direction opposite to the one direction.

    摘要: A light-light transfer method using a spatial light modulator realizes an image display with a high utilizing of light without causing an undesirable residual image. The spatial light modulator is constituted to include two electrodes and at least a photoconductor layer member and a photo-modulation layer member used in a birefringence operating mode both being sandwiched between the two electrodes. A writing light is entered from the photoconductive layer member side so that its exposure value varies from the minimum exposure value to the maximum exposure value in a condition that a predetermined operation voltage is supplied between the two electrodes. In this instant, a voltage applied between both ends of the photo-modulation layer member corresponds to a voltage obtained by subtracting a voltage drop amount, occurring in the photoconductor layer member due to an incidence of the writing light, from said predetermined operation voltage applied in advance between said two electrodes. An operational condition of the spatial light modulator is set so that the voltage applied between both ends of the photo-modulation layer member becomes a voltage monotonously exceeding a voltage value corresponding to an extreme value of a degree of photo-modulation in a characteristic curve showing a relationship between an applied voltage and a degree of photo-modulation in the photo-modulation layer member, at the timing when the writing light of the maximum exposure value is entered into the spatial light modulator.
