    摘要: A spectacle lens includes a first region which is located in at least part of a portion of a lens where a pivotal angle of an eyeball of a wearer ranges from 20 to 60 degrees and in which correcting astigmatism has priority over correcting average power based on prescribed power, and a second region which is formed inside the first region and in which correcting the average power has priority over correcting the astigmatism.

    摘要: A progressive addition lens includes a portion having a power for viewing a near field, a portion having a power for viewing a distance field further than the near field, and an portion connecting the distance portion and the near portion. The progressive addition lens includes an aspherical object-side surface and an aspherical eyeball-side surface and is formed in rotational symmetry with respect to a center of design of the progressive addition lens. The object-side surface includes a first stable region formed in rotational symmetry with respect to the center of design and including the center of design, and an aspherical region arranged outside of the first stable region to contact the first stable region and formed in rotational symmetry with respect to the center of design. A PV value (Peak to Valley) of a mean surface refractive power in the first stable region is 0.12 D or less.

    摘要: When an addition power at a position corresponding to a fitting point within a prescription addition power is greater than a target addition power set according to a target distance, the target addition power is set as an addition power between a progression-start point and a progression-end point on a principal meridian, and in addition the average gradient of an addition power between the progression-start point and the fitting point is set to differ from an average gradient of an addition power between the fitting point and the progression-end point. When the addition power at the position corresponding to the fitting point within the prescription addition power is equal to or smaller than the target addition power, a gradient of the addition power is made constant in a partial region including at least the fitting point between the progression-start point and the progression-end point on the principal meridian.

    摘要: To provide a junction structure and a junction method for conductive projection advantageous in that a required reinforcement strength can be obtained while suppressing the amount of a reinforcing resin material supplied to prevent warpage due to curing shrinkage. A conductive projection is joined to the surface of a conductor portion formed at the same level as that of the surface of the insulating layer so that a root portion of the projection is surrounded by a fillet-form resin material. The resin material contains an activator which assists in the junction between the conductive projection and the conductor portion when the resin material is in an uncured state, and is fused by heating to wet and rise the root portion of the conductive projection so as to be in a fillet form. The resin material is cured by an ultraviolet light while excluding the resin material on the conductor portion.

    摘要: A refrigerator with a regenerator is provided which is supported by a holder. The refrigerator has a cylinder having an inner circumferential surface matching a circular tube shape, a displacer being disposed in the cylinder and forming an expansion space near at one end of the inside of the cylinder, a groove pattern having a groove formed along the direction intersecting the axial direction of the displacer, the groove allowing a gas flowing through a gap between the cylinder and displacer from one end to the other end of the outer circumferential surface of the displacer to positively heat-exchange with the cylinder and displacer, and a main gas passage for supplying gas to the expansion space of the cylinder and recovering the gas from the expansion space. The holder supports the refrigerator so that the axial direction of the cylinder is directed in the vertical direction and the expansion space is formed at the upper end of the inside of the cylinder, or the axial direction of the cylinder is directed in an oblique direction relative to the vertical direction.
