摘要:
A disclosed optical add/drop multiplexing device demultiplexes a first signal into multiple signals according to wavelengths, drops one or more of the demultiplexed signals to a transponder, adds one or more signals output from the transponder, multiplexes these signals into a second signal, and outputs it. The device includes an injecting unit for injecting one of measurement signals, each of whose wavelength corresponds to that of a different demultiplexed signal, into a core of a multicore cable within the device, the core being used to transmit the different demultiplexed signal having the corresponding wavelength; a preventing unit for preventing the one measurement signal from emanating; a measuring unit for measuring, for each wavelength, levels of the one measurement signal before and after the corresponding core; a calculating unit for calculating loss of the corresponding core, based on the measured levels; and an informing unit for reporting the calculated loss.

An unmoldability determination apparatus includes: a normal line calculation unit that calculates a normal line extending from a point on each of surfaces constituting a three-dimensional shape of a molded product; an opposite direction component determination unit that determines whether or not the normal line calculated on each surface has an opposite direction component which is a directional component opposite to a mold release direction of a mold of the molded product prescribed for the each surface; a reach determination unit that, when a surface having a point at which the normal line having the opposite direction component is calculated is a projection surface, determines whether or not there is another surface on the molded product which one of a line extending from the projection surface in the mold release direction and a line extending in a direction opposite to the mold release direction reaches; and an unmoldability determination unit that, when there is another surface which both of the line extending from the projection surface in the mold release direction and the line extending in the direction opposite to the mold release direction reaches, determines the projection surface to be unreleasable from the mold only by movement of the mold in the mold release direction, thus determining the projection surface to be unmoldable.

A shape inspection apparatus includes a shape display unit that displays a three-dimensional shape specified by three dimensional shape data on a screen; a direction designating unit that specifies a drawing direction in molding the three-dimensional shape on the screen; a face designating unit that specifies one face of a protruding or recessed shape portion of the three-dimensional shape on the screen; a dimension calculating unit that calculates a shape dimensional value of the shape portion based on the specified drawing direction and the specified one face; and a determination unit that determines whether or not the shape portion having the shape dimensional value satisfies a shape condition by comparing the calculated shape dimensional value with a standard value.

An information processing apparatus includes a restriction section, an acquisition section and a change section. The restriction section restricts maximum amount of stored data to be stored in each of information storage area in response to a reference value predetermined to each of information storage area. The acquisition section acquires relevant information about the stored data stored in each of the information storage area. The change section that changes the reference value determined to each of the information storage areas based on the acquired relevant information.
