The invention provides a heat exchanger and an air conditioner. The heat exchanger can be used as a condenser or an evaporator. Partition boards are disposed in the collector tubes so that a plurality of distribution chambers are formed in the collector tubes; a plurality of inlet tubes and outlet tubes are provided; and accordingly coolant can be distributed. When a warm room operates, vortexes formed by the coolant in the distribution chambers are sprayed up from spray holes on the distribution chambers to form jet flows, the coolant is pelletized and equally enters flat tubes, and accordingly annular flows with good heat transfer effect are formed, the parts are subjected to even heat exchange and the performance of the heat exchanger is improved. When a cold room operates, gas coolant continuously radiates heat outside through pipelines to form liquid condensate or gas-liquid flows, and the liquid condensate or gas-liquid flows enter the distribution chambers from the lower spray holes of the spray chambers in the first collector tubes and are discharged from the inlet tubes. In addition, the size of coolant pellets is reduced, impact of the coolant pellets upon the inner walls of the tubes and pellet collision are inhibited, and accordingly flowing noise of the coolant can be reduced.

A method to update firmware in a plurality of peripheral devices and a computer using the method to reduce data transmission collisions and to reduce the time required to complete the update process. The process involves sending firmware update data from a computer that is connected to a communication network to printers or other peripheral devices that are also connected to the communication network. The computer 11 groups a plurality of peripheral devices (such as printers 13a1) connected to the communication network into separate transmission unit groups each containing up to a maximum number of peripheral devices with the maximum number determined by measuring the transmission speed of the network and thereafter deriving the maximum number by experimentation at the measured transmission speed. The update data for updating the firmware is transmitted to the peripheral devices of any one transmission unit group. Thereafter update data is sequentially transmitted to the peripheral devices in another transmission unit group but not until the completion of transmitting the update data to all of the peripheral devices in the first transmission unit group is confirmed.

The Cableveyor may be able to support its own weight in the direction of gravity since the Cableveyor having the bent portion that connects between the straight-moving unit and the rotating unit is arranged so that it bends in a horizontal plane. As a result, the Cableveyor and the maintenance member do not collide, thus collision noise or dust caused by the collision can be suppressed. Moreover, since the Cableveyor is arranged to the side of the straight axis, the height size of the robot can be suppressed compared with the composition that arranges the Cableveyor on the upper surface of the straight axis.
