Patent number: 6719377Abstract: A method and device for driving a pump of a brake system, in which a pump motor achieves full drive for a particular time following a braking request from the brake system. During the subsequent clocked driving action, a drive signal is subjected to a pulse width modulation based on a direct comparison between a motor voltage and a voltage threshold value. Due to a subsequent comparison between the motor voltage and a safety threshold, and the resulting full drive for the particular time, an increased load on the pump causes the pump to produce the necessary delivery capacity. In addition, a selectable maximum off-time of the pump motor guarantees a minimum pump on-time per drive cycle. The pump can be made to achieve full drive prematurely as a function of certain conditions which can be subjected to a preventive check, thereby avoiding an excessively high load. It is also possible to coordinate the way in which different control strategies access the pump.Type: GrantFiled: March 23, 2000Date of Patent: April 13, 2004Assignee: Robert Bosch GmbHInventors: Christian Zimmermann, Oliver Lah, Helmut Wandel

Patent number: 6719396Abstract: A unit heat value Qpass (=Ipass2·tpass) per pass is calculated from a current value (an effective current value) Ipass of a carriage motor with one pass of a carriage (one-way running in a reciprocation) and a moving time (a motor driving time) tpass of the carriage. Then, the unit heat value Qpass is successively calculated to obtain a heat value Qsigma for a unit time Tbox(=one minute). The heat value Qsigma is converted into a heat generation temperature &Dgr;Tnew. The heat generation temperature &Dgr;Tnew is successively added in consideration of a spontaneous radiation with the passage of time to obtain a current heat generation temperature &Dgr;Tsum (&Dgr;Tsum=K·&Dgr;Tsum+&Dgr;Tnew; K is a radiation factor). When &Dgr;Tsum exceeds a threshold, a pause time for one pass of the carriage is provided.Type: GrantFiled: September 3, 2002Date of Patent: April 13, 2004Assignee: Seiko Epson CorporationInventor: Sumito Anzai

Patent number: 6719398Abstract: An inkjet printer includes a printhead having a plurality of ink orifices formed therein. During printing, ink drops are ejected through the ink orifices into a print zone between the printhead and a print medium with an intended ink drop trajectory toward the print medium. An air movement system directs an air stream to the print zone substantially parallel to the intended ink drop trajectory as the ink drops are ejected during printing so as to affect air currents acting on the ink drops during printing and prevent print defects caused by the air currents. The air stream, however, does not disrupt the intended trajectory of the ink drops during printing.Type: GrantFiled: October 2, 2000Date of Patent: April 13, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: David McElfresh, Satya Prakash, Naoto Kawamura

Patent number: 6719403Abstract: A high-quality image is printed with reduced bleeding in colors that may appear at a boundary between a black image and a color image. A head for ejecting black ink and a head for ejecting color ink perform three times of scanning while feeding is carried out therebetween for moving the printing medium by four pitches of ejection openings arranged on the heads, different ejection openings are caused to correspond to a scanning area, which corresponds to the four pitches, and multi-pass printing is performed to complete printing on the area. The black head completes printing of the black image, and then, the color head completes printing of the color image adjacent to the black image. The arrangement of ejection openings is determined so that between last scanning for completing printing of the black image and the first scanning for printing of the color image, scanning with no performing printing exists.Type: GrantFiled: November 30, 2001Date of Patent: April 13, 2004Assignee: Canon Kabushiki KaishaInventors: Hidehiko Kanda, Jiro Moriyama, Yoshinori Nakagawa
