摘要:
Embodiments of the present invention provide a production planning method and system. Where a manufacturing apparatus is shared by a plurality of products in a production line, if a manufacturing (production) availability number is changed, a cause parameter is automatically investigated so that a production plan with high precision can be prepared in a short time. With respect to a production plan as the previous/current comparison objects, a production process used in the production plan in which a change occurs, is extracted. From the production process, a parameter item to be used in the production capacity evaluation is extracted for all products, a difference comparison is made between the value of the previous parameter and the value of the current parameter, so that the parameter item as the cause is specified. The combination of the cause parameter items is calculated, and a cause parameter list is prepared. Next, from the specified parameter list, the parameter item is sequentially changed, and the manufacturing (production) availability number is recalculated. An influence index given to the manufacturing (production) unavailability number by the cause parameter, is calculated.

An IC for an active terminator has not only a plurality of pairs each corresponding to a different line of a bus and including a terminal resistor and a buffer amplifier which serves to output a specified voltage through the corresponding terminal resistor to the corresponding bus line, but also a similar pair of an additional buffer amplifier and an additional resistor. One end of the additional resistor is connected to the additional buffer amplifier and the other end of the additional resistor is connected to a pair of pads. Each of these terminal resistors may be connected to adjustment resistors each connected to its own additional buffer amplifier serving to output a specified voltage through the corresponding adjustment resistor to the corresponding line. These additional buffer amplifiers are controlled by a control signal received through their individual control lines which are grouped, the lines in each group being connected together into a common line which contains a repair part where it can be cut.

A flexible engagement gear device (11) has a silk-hat shaped flexible external gear (13) which has a body part (22), a diaphragm (23) and a boss (25). The diaphragm (23) has a plate-shaped part (28), a sectional shape of which, when cut along a plane including a device axial line (11a), is defined at one side by a straight line (232) extending in a radial direction, and at the other side by a first convex circular arc (240), a concave circular arc (250) and a second convex circular arc (260) in this order from the side of the boss. Among these arcs, the first convex arc (24) has the largest curvature, while the concave circular arc (25) has the smallest curvature. The concave circular arc (250) is positioned at the middle of the plate-shaped part (28), the thickness of which is the smallest in the plates-shaped part (28). If the flexible external gear having this cross section is used, when the axial length is reduced, the stress concentration can be relieved without increasing the outer diameter.

摘要:
A wave gear drive comprises a circular rigid internal gear and a flexible external gear inside the rigid internal gear. A wave generator in the flexible external gear flexes the flexible external gear into an elliptical shape. The cross-section of the flexible external gear perpendicular to the axis at a point in the tooth trace direction of the flexible external gear is set as the main cross-section. The rigid internal gear and flexible external gear are gears with a module m, and the flexible external gear has a number of teeth that is smaller than the number of teeth of the rigid internal gear. The moving route M of a tooth of the flexible external gear with respect to a tooth of the rigid internal gear that accompanies rotation of the wave generator when meshing of the teeth in the main cross-section is approximated by rack meshing. On the entering side of the meshing of the teeth to the major axis of the moving route M, a first similar curve AC is obtained by similarity transformation of a pressure angle α orthogonal to the direction of the moving route M. The first similar curve AC is employed as the basic addendum tooth profile of the rigid internal gear. A second similar curve CB is obtained by rotating the first similar curve AC 180 E about endpoint C, and by a similarity transformation in which the first similar curve AC is multiplied by a ratio of similitude (1-λ)/λ The second similar curve CB is employed as the basic addendum tooth profile of the flexible external gear.
