Patent number: 8469473Abstract: An inkjet recording apparatus includes a recording head having three rows of nozzles which are three-phase driven and arranged in a staggered arrangement. The nozzles are arranged in the main scanning direction at an interval of L/3, where L is a pixel pitch, and each nozzle row is ejection-driven in the sequence from the last nozzle row to the forward nozzle row in the moving direction of the recording head. The recording head scans at a moving speed of 2×L×f, where f is an ejection frequency per nozzle row. After the completion of one scan, the recording medium is moved a distance of predetermined multiples of the pixel pitch in the sub-scanning direction, and in the next scan, ink is ejected onto the recording medium at pixel positions other than the pixel position on which the ink has landed in preceding scans.Type: GrantFiled: February 12, 2010Date of Patent: June 25, 2013Assignee: Konica Minolta Holdings, Inc.Inventors: Hiroaki Arakawa, Takahiro Matsuzawa

Patent number: 7088607Abstract: The objective of this invention is to provide a static memory cell and an SRAM device that can improve the write margin while preventing degradation of the static noise margin. By turning on/off transistor Qp13, it is possible to control the drop in voltage due to the threshold voltage of transistor Qn15. For example, in read mode, when it is necessary to hold the stored data while setting word line WL to the high level, transistor Qp13 is turned off; the drivability of transistor pair Qn11, Qn12 is decreased, thereby increasing the static margin. In the case of rewriting the stored data, transistor Qp13 is turned on; the drivability of transistor pair Qn11, Qn12 is increased, thereby increasing the write margin. As a result, it is possible to improve the performance of both the static noise margin and the write margin.Type: GrantFiled: February 24, 2005Date of Patent: August 8, 2006Assignee: Texas Instruments IncorporatedInventors: Takahiro Matsuzawa, Yoritaka Saitoh, Masayuki Hira
