    摘要: It is aimed to smoothly perform engagement and disengagement of a fastener of a packaging bag and easily take out an inner content by a desired amount. For these purposes, in a packaging bag 1 with a fastener 20 in which a male fastener element and a female fastener element are attached to inner surfaces of opposing flat surface portions 2a and an opening is opened or closed by engaging or disengaging both the fastener elements, pick-up tabs 40 are provided so as to project outward at a portion corresponding to a mounting portion of the fastener 20, or near the portion. The fastener is formed to be asymmetric with respect to the center thereof so that one side largely protruded is attached so as to be directed inward of the packaging bag.

    摘要: A spatial light modulator includes an electro-optic crystal plate and a mesh electrode for capturing secondary electrons emitted from the crystal plate. Primary electrons carrying an image corresponding to an input optical image are incident on the front surface of the crystal plate to write a charge pattern thereon. In a writing operation, a dc voltage and a ramp voltage is applied to the mesh electrode and the back surface of the crystal plate, respectively. The dc voltage and a variation range of the ramp voltage are shifted to obtain a desired input/output characteristic of the device. Alternatively, a decreasing rate of the ramp voltage is changed to obtain a desired characteristic.

    摘要: An object is typically illuminated by laser light, and reflected light carrying a speckle pattern is amplified by an image intensifier. First and second speckle patterns representing the object before and after its deformation, respectively are written by double writing into a ferroelectric liquid crystal spatial light modulator (FLC-SLM). The double-written image is read out from the FLC-SLM, and converted by a Fourier transform optical system into an output optical image, i.e., Young's fringe. The output optical image is detected by a photoelectric converter, and analyzed by an image processing device to determine a deformation of the object.

    摘要: A crystal structure arrangement used in a spatial light modulator wherein an electrooptic crystal structure faces an electron beam source, such as a photocathode or an electron gun, within a vacuum envelope. Electrons emitted from the electron beam source in response to an image or image signal source are stored on the surface of the electrooptic crystal structure to form a charge image thereon and then to change the refractive index of the electrooptic crystal structure corresponding to the stored charge image. The refractive index change is read out using a laser beam or incandescent light beam.
