Abstract: The present invention relates to a display module for visually impaired persons. More specifically, the present invention provides a display module for visually impaired persons which provides information such as braille, figures and images by using a plurality of protrusions which vertically moves so that a visually impaired person may obtain information through hand sensation.

Abstract: The present invention relates to a braille editing method using an error output function, a recording medium storing program for executing the same, and a computer program stored in a recoding medium for executing the same. More particularly, the present invention relates to a braille editing method using an error output function, a recording medium storing program for executing the same, and a computer program stored in a recoding medium for executing the same, that are capable of finding a location where a braille translation error has occurred by utilizing index information when detecting the error and thus facilitating correction.

Abstract: The objective is to prevent the loosening of a structure with which a member 80 to be fastened and a base material 90 are fastened through a male screw body 10 and a washer 50. A screw-body-side seat part 22 is formed on the male screw body 10, and a first receiving part 60 and second receiving part 70 are formed on the washer side. A member-side seat part 82 is formed on the member 80 to be fastened. The first receiving part 60 and the screw-body-side seat part 22 have sawtooth-shaped recesses and protrusions. When an attempt is made to rotate the male screw body 10 in the direction of loosening, the recesses and protrusions engage one another, thereby preventing rotation. A recessed housing part of the member-side seat part 82 and the outer wall of the second receiving part 70 of the washer 50 have an eccentric circular shape. When an attempt is made to rotate the washer 50 in the direction of loosening, the eccentric circular shapes engage one another, thereby preventing rotation.

Abstract: [Problem] The purpose of the present invention is to provide a form-rolling die and form-rolling method for a compound screw that use a cylindrical material to be threaded, enable the high-precision mass production of compound screws having a right-hand thread portion and a left-hand thread portion on the same region, do not cause rolling defects such as slips, and in which blockages do not occur even in the unlikely event of shavings being generated. [Solution] A form-rolling die structure is provided with die members which are pressed against a material to be threaded and which have rigid surfaces that are relatively displaced. The die members are equipped with a plurality of independent concave portions which form a substantially parallelogram shape when viewed from the normal of a virtual surface obtained by connecting the outermost portions of each of the rigid surfaces, and which are recessed from the virtual surface.

Abstract: [Problem] The present invention aims to provide, without an increase in cost, a directional indication structure for threaded bodies that enables the visual and tactile distinction between left-hand thread and right-hand thread threaded bodies, enables the identification, from the external appearance and the external surface, of which direction a threaded body should be rotated in order to be tightened or loosened, enables mass production and the like, has a good external appearance, and has form properties that do not impinge the properties inherent in the threaded body or the strength, etc.
