摘要:
A packet multiplexer capable of realizing the optimization of a communication path automatically, without requiring a user to explicitly specify for it, is disclosed. The packet multiplexer is formed by a plurality of first communication interfaces for terminating a plurality of C-plane and U-plane pairs on one side of the packet multiplexer, a second communication interface for terminating a single C-plane and a plurality of U-planes on another side of the packet multiplexer, a connection interface for multiplexing the C-plane and U-plane pairs terminated at the first communication interfaces into the single C-plane and the plurality of U-planes terminated at the second communication interface, and a control unit for controlling multiplexing of U-planes by the connection interface according to signaling through C-planes, such that a cut-through is made within the packet multiplexer between two U-planes terminated at the first communication interfaces that form a loop.

There is disclosed an image processing system composed of a network of plural stations, in which the transmitted image signals can be monitored on real time basis, always utilizing the full image display area and without lack in the displayed image, by suitably converting the image signals.
摘要:
A steering wheel assembly including an insulated base having a surface; a plurality of segmented slip rings having surfaces, disposed separately on the insulated base along a circular line such that they are mutually insulated; a plurality of contact pins that make sliding contact with the segmented slip rings along the circular line, and are set facing the surfaces of the segmented slip rings; and interposing pieces provided between the adjacent segmented slip rings such that the contact pins can move smoothly across the segmented slip rings.
摘要:
A microprocessor-based telephone set includes a telephone number memory, a number indicator, an abbreviated number scanning switch and associated control circuit, in addition to a push-button dial and a hook switch as equipped in the usual telephone set. Telephone numbers are preset in correspondence to abbreviated numbers, so that a telephone number is dialed automatically by simply specifying a corresponding abbreviated number using the scanning switch and indicator. By provision of an FM transceiver within the handset and a separate relay unit for establishing radio communication with the base telephone station, a mobile telephone system is configured.
摘要:
A steering wheel comprises a rotatable steering shaft, a boss fixed onto the steering shaft, a pad non-rotatable mechanism mounted on the boss and used to hold pad means stationary, a support member for attaching the column-side non-rotatable member of the pad non-rotatable mechanism to the boss in such a manner that the column-side non-rotatable member is rotatable relative to the boss and stopper means provided on the column-side non-rotatable member and used to make the column-side non-rotatable member non-rotatable relative to a column.
