Abstract: A communication device includes: a MAC unit that processes a main signal including a payload, and determines a communication timing of the main signal; a communication unit that performs, based on the communication timing, at least one of transmission processing for E/O converting the main signal acquired from the MAC unit, and transmitting the main signal to a communication counterpart device, and reception processing for O/E converting the main signal received from the communication counterpart device; a main signal transmission line through which the main signal is transmitted between the MAC unit and the communication unit; and a control information transmission line that is provided separately from the main signal transmission line, and through which communication timing data that is data indicating the communication timing is transmitted from the MAC unit to the communication unit.

Abstract: An automatic drug dispenser includes: a drug cassette which ejectably accommodates drugs; a base unit which detachably supports the drug cassette and drives a motor to eject drugs; a drug feeder storage which is designed to store a large number of base units; a reading device which is provided in each of the base units and reads identification information assigned to the drug cassette; and a checking means which compares a result of reading with pre-stored check data, wherein a microprocessor is mounted in each of the base units, and the checking means, the check data and history information related to the cassette are built in each microprocessor in a distributed manner.

Abstract: A lag screw for connecting a bone portion separated from the femur, by fracture, to the main portion thereof is fixedly secured in the separated bone portion and extends through main portion of the femur. A nail member is installed in the femur in order to fix the lag screw to the femur. The lag screw is secured in the nail member by a set screw inserted into an outer end of the nail member. In order to prevent the rotation of the separated bone portion about the lag screw, an auxiliary connector is inserted through the nail member between the lag screw and the set screw. The lag screw is clamped by the set screw via a spacer for transmitting a clamping force.
