    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.

    摘要: In a cryogenic refrigerator using a Gifford MacMahon (GM) cycle, a rotary valve device (RV) for controlling the supply and discharge of refrigerant gas with respect to the refrigerator (2) is adapted by a reversible motor (15) to be rotated in normal and reverse directions, and during the rotation in the normal direction, a cooling mode operation for producing cold by an adiabatic expansion is effected, and during the rotation in the reverse direction, a temperature-raising mode operation for producing heat by an adiabatic compression is effected. In order that the optimum efficiency can be obtained in each of the cooling mode operation and the temperature-raising mode operation, the timing of opening and closing of the rotary valve device (RV) with respect to the reciprocal movement of displacers (3a, 3b) during the rotation in the normal direction is made different from said timing during the rotation in the reverse direction. As a result, the time required for raising the temperature of a cooling portion in a cryogenic condition to the normal temperature can be shortened without the need for any special equipment.
