Abstract: PURPOSE:To discharge fine ink mists produced from ink droplets together with a recording medium out of a device by controlling in such a manner that the capacity of a fan is increased as the temperature of a recording head rises and shielding a recording surface formation part by means of an air cutain blown off from the fan. CONSTITUTION:When a signal RTH, reporting that the temperature of a recording head unit has risen, is sent from a recording head unit 110 to a control unit CTL, the CTL sends a signal DFH to a DC fan motor M4 for sucking printing paper P to increase the capacity of a fan, so that an air flow from a fan 390F for sucking paper is deflected by a duct member 390D to be blown off from a gap between a platen 392 and a mount base 302 so that the air flow runs against a printing surface (direction of arrow A) of the paper P to form an air curtain. As a result, fine ink mists produced by projection of ink of a head 110 are uniformly attached to the paper P, while the mists are discharged out of a device, preventing thereby the device from being contaminated.

Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To facilitate detection especially of a small signal buried in the range side lobe of a large receiving signal in a radar having a function for compressing a receiving signal. SOLUTION: From the compression results of a receiving data compressor 9, a maximum signal detector 10 determines a signal having a large amplitude as an output signal of a signal extraction unit.
