Abstract: A slider body of a slider includes a slider main member and a slider sub-member. The slider main member includes at least a portion of a first blade and at least a portion of a second blade which are connected to each other through a guide column. The slider sub-member includes a pair of first flange sections and is assembled with and fixed to the slider main member. The slider can easily be attached to a fastener chain. Since the slider stably has a predetermined distance between the first and second blades, it is possible to secure satisfactory sliding properties and operability of the slider.

Abstract: The slide fastener attachment method includes: integrating, by welding or bonding, a fastener chain to which a segmented slider has not been attached and a fastener receiving member, and attaching the slider to the fastener chain after the integration. Thus, welding work operation efficiency is improved, and reduction of production cost can be expected.

Abstract: Disclosed herein is a method of displaying an existence probability of an electron in a hydrogen atom. In the method, N radii are referred to as r1 to rN in ascending order. An area proportional to the surface area of a sphere having a radius rn (n is any of 1 to N) is referred to as Sn. A value proportional to an existence probability of an electron at a distance rn from the center of a hydrogen atom is referred to as Pn. The method includes displaying a circle having an area Sn for all n from 1 to N in a concentric manner, and displaying small symbols which are Pn in number on the circle having the area Sn in an equally spaced manner for all n from 1 to N and in such a manner that small symbols associated with a circle having a larger radius is partly hidden behind a circle having a smaller radius.

Abstract: A method of sewing a fastener stringer includes the steps of conveying a fastener stringer and an attached body to a sewing section of a sewing machine in a state with the fastener stringer superposed on the attached body, and arranging an element guide section in the sewing section of the sewing machine, bending a fastener tape in a direction in which a tape bent section opens, guiding the element rows to the element guide section, and sewing the fastener tape to the attached body. Accordingly, the method enables a sewing line formed by a sewing thread to be disposed at a predetermined position and the fastener tape and the attached body to be easily and efficiently sewn together.

Abstract: A fastener attached product is structured such that a slide fastener is sewn to right and left attached bodies which are bent in a U-shape, and the right and left attached bodies are arranged in a tape surface side to which the element rows of the fastener tape are sewn. Further, the right and left attached bodies come into contact with the outer surfaces of right and left flanges which are arranged in a slider, and the element rows are arranged and exposed between the right and left attached bodies. As a result of this configuration, since the fastener tape is invisible from the outside by the attached body, exposing the element rows can provide the fastener attached product with different design from conventional products and eliminate problems due to degradation in the appearance and design which is caused by the exposure of the fastener tapes.

Abstract: The method assumes that a single solution or addition or subtraction of solutions of Schrodinger equation represented by polar or parabolic coordinates having its maximum value at the origin gives a wave function and an electric potential of a hydrogen atom. The method further: (1) regards the result of applying a gradient vector operation and thereafter a sign inversion to the wave function as an electric field; regards segments connected successively along the direction of the electric field as electric lines of force; and draws the electric lines of force so as to be approximately proportional in number to the percentage of the wave function with a difference between the maximum and minimum values of the wave function regarded as 100; and (2) displaying the wave function as an electric potential in a contour drawing.

Abstract: A hydrogen atom model has a drawing or three-dimensional model which expresses an electric field in a form of electric lines of force and a magnetic field in a form of magnetic lines of force, as an example. The electric field is obtained by a gradient vector operation applied to a wave function of a hydrogen atom and a sign inversion to the result of the vector operation. The magnetic field obtained by multiplication of the wave function by a ?-directed unit vector in polar coordinates (r, ?, ?) and application of a rotational vector operation to the result of the multiplication.

Abstract: A hydrogen atom model is a three-dimensional model or planar drawing which expresses an electric field in a form of electric lines of force and a magnetic field in a form of magnetic lines of force. The electric field is obtained by a gradient vector operation applied to an electric potential and a sign inversion to the result of the vector operation. The electric potential is a wave function of any one of orbitals of a hydrogen atom. The magnetic field is obtained by a rotational vector operation applied to a vector potential. The vector potential is the wave function regarded as a vector potential having a component only in a ?-direction of polar coordinates (r, ?, ?).

Abstract: A rotational operator is applied once or twice to a product of a wave function of quantum mechanics for a dynamic system and a unit vector in a ?-direction in a polar coordinate system (r, ?, ?) to obtain a first or second vector function, respectively. A starting coordinate is substituted into the first or second vector function to obtain a starting value of the vector function, and a next coordinate a small distance away from the starting coordinate in a direction of the starting value of the vector function is calculated. This process is iterated and segments linking the coordinates one after another are drawn on a medium, such as a sheet, as a magnetic or electric line of force. The process is iterated with replacing the initial starting coordinate with another initial one to obtain another magnetic or electric line of force.

Abstract: A wave function of quantum mechanics is regarded as a vector potential having a component only in a ?-direction of polar coordinates (r, ?, ?). The result of applying a rotational vector operation to the vector potential is regarded as a magnetic field. The result of applying the rotational vector operation to the magnetic field is regarded as an electric field. A drawing on a plane or a three-dimensional model is configured to express both the magnetic and electric fields or one of the fields. The drawing or the model, as an educational tool, visualizes the figure of an atom, enables educands to have a close feeling toward sciences, and especially quantum mechanics, and enables them to have concrete images of various physical phenomena in the atom.
