In an ink jet apparatus for manufacturing a color filter 1, ink jet heads 22 having a plurality of nozzle 27 are disposed in a linear manner. The voice and data is formatted into network data packets that are then routed directly to different endpoints through the network access server. This is achieved in one embodiment by locating those components adjacent to the flexible membrane. Each of the second descriptors comprises the third descriptor and fourth descriptor. The methods described are useful in the diagnosis, treatment and prevention of cancer, particularly breast and ovarian cancer. When the actuator at the refuge place starts loading with a starter command, a pulsed driving current is applied to the voice coil temporarily for urging the tab against a tab-holding plane of the ramp section, thereby making use of repulsion force generated on the actuator, so that the tab can leave the refuge place efficiently for carrying out the loading operation.
