Abstract: Rotary support bodies which support both ends of a rod penetrating a manipulating knob body are formed by joining a first rotary support member which is arranged at one side of the manipulating knob body and supports one end of the rod and a second rotary support member which is arranged at another side of the manipulating knob body and supports another end of the rod, and one end of the rod is fixed to the second rotary support member, and another end of the rod is engaged with the first rotary support member. Accordingly, a manipulating knob can be mounted on a casing in a state the manipulating knob is mounted on the rotary support body.

Abstract: An asynchronous transfer mode (ATM) controller includes a buffer memory, a transfer circuit which transfers packet data between the buffer memory and an internal memory of an associative terminal unit with a data block of predetermined length being a unit therefor, a cell transmit circuit section that subdivides or “slices” the predetermined length data block sent from the terminal memory to the buffer memory into data cells which are then sent forth to the ATM network, a cell receive control circuit operable to reconstruct or re-assemble those data cells received from the ATM network over a transfer path thereby forming in the buffer memory a predetermined length data block, and a transfer control circuit operable to permit or “instruct” the transfer circuit to transfer the predetermined length data block between the buffer memory and the terminal memory and also instruct both the cell transmit control circuit and the cell receive control circuit to transfer the data cells between the

The ATM controller performs the processing of an ATM layer and an AAL layer between a terminal and an ATM network, and comprises cell transmit control moans for transferring a packet from a terminal side to an ATM network side while segmenting the packet into data cells, cell reception control means for reassembling data cells received from the ATM network side into a packet and transferring the packet to the terminal side, a rewritable memory for storing a firmware, and a microprocessor for performing a cell analysis and the processing corresponding to the analysis result.

Abstract: A rotation detecting device which issues a plurality of code signals by a simple configuration so as to detect the rotational angle position and the direction of rotation of a rotor according to the code signals. The rotation detecting device has a knob member which is rotatably attached to a part of an enclosure, a plurality of projections which are formed on the periphery of one end of the knob member, and two detection switches which selectively engage with the projections to turn ON/OFF and issue signals. These detection switches are disposed on a printed circuit board in such a manner that they turn ON/OFF at different timings as the knob member rotates. Thus, the rotational position and the direction of rotation of the knob member are detected by the combinations of the ON/OFF signals of the detection switches.

The protocol processor is also connected to the buffer memory through a third path so as to effect protocol processing on the communication data within the buffer memory.

Abstract: A protocol high-speed processing method to be used in a first communication control equipment for communications with a second communication equipment connected through a transmission line in accordance with a predetermined communication protocol. The communication control equipment predicts the type of communication frame to be received next from the communication line, in accordance with type of communication frame previously transmitted to or received from said transmission line, and prepares information necessary for a process of receiving said predicted communication frame and information of a part of the communication frame to be transmitted subsequent to the receiving process, to await the reception of a next communication frame. As a result, the receiving process time and the response process time can be reduced when the actually received communication frame is consistent with the predicted one.
