The present inventions relates to a design evaluation method, equipment thereof, and a goods design method that make it possible to obtain a highly reliable evaluation of a design quality of an evaluated object. Thus, in the present invention, the design of an evaluated object is evaluated on the basis of a brain wave reaction by outputting an image, which expresses the design of the evaluated object, by image output means, and measuring brain waves of an arbitrary test subject by showing this image to the test subject. Hence, it is possible to obtain a highly reliable evaluation result without any subjective judgment based on the knowledge and experience of the test subject.

When an input shaft 6 is rotated by an external driving force, the resultant rotational force of the input shaft 6 is transmitted to an offset housing 21 of which rotational force in turn is transmitted to variable rings 39. If, at that time, angular volocities of the variable rings 39 are periodically varied relative to the angular velocity of the offset housing 21, the periodically varying angular velocities of the variable rings 39 are corrected to be substantially constant in a predetermined phase range, allowing only rotational forces having corrected angular velocities to be fetched from the variable rings 39 for transmission to an output shaft 7. Thus, by arbitrarily varying the angular velocities of the variable rings 39 relative to the angular velocity of the offset housing 21, the rotational speed of the output shaft 7 is steplessly varied relative to the rotational speed of the input shaft 7.

The present invention provides an insulating spacer for a high-voltage conductor constructed with a plastic made of an epoxy resin composition so that the volumetric specific resistance of the shield electrode increases toward the median point between a container and the conductor and a method for manufacturing shield electrode used therein. The insulating spacer according to the present invention can lessen the concentration of electric fields in the boundary areas between the shield electrode and the insulating member with the result that reliability is improved and service life is lengthened.
摘要:
A differential gear is capable of differentially setting magnitudes of differential limiting forces depending on directions of rotational force transmission. A rotational force of the input-side rotary element is transmitted by way of rolling elements and grooves to the rotary elements. The rolling elements roll along grooves of the rotary elements while reciprocating within elongated holes of the retainer element, thereby permitting the difference in speeds of rotation between the rotary elements. The differential motions of the rotary elements are limited by axial reaction forces generated between the rotary elements and the grooves. At that time, if the directions of the rotational force transmission between the input-side rotary element and the rotary elements differ from each other, then the magnitudes of the axial reaction forces generated between the rotary elements and the grooves will also be different from each other. Hence, differential limiting forces are generated which differ in magnitude from one another depending on the directions of transmission of rotational forces. According to the present invention, therefore, a small and low-cost configuration is achieved and there can be generated differential limiting forces having any magnitudes which differ between upon the acceleration and deceleration of automobiles. A secure coping will thus be ensured with running performances of automobiles, objects of use and combinations with attached mechanisms, thereby remarkably enhancing utility value as the differential gear having a differential limiting function.
