Abstract: A fluid pump comprising a plurality of piston cylinders (1, 2, 3, 4), wherein each individual cylinder has a piston rod (5, 6, 7, 8) with a piston (9, 10, 11, 12) arranged in the cylinder and a valve housing (13, 14, 15, 16) mounted at the end of the cylinder opposite the piston rod, and a drive arrangement for the piston rods, said drive arrangement comprising two main gearwheels (17, 18) which mesh and rotate in opposite directions. The present fluid pump is characterized in that the reciprocating motion of the piston rods (5, 6, 7, 8), which extend in pairs in opposite directions, is effected with the aid of two beams (19, 20) that are fixed to the end of the respective pair of piston rods opposite the pistons (9, 10, 11, 12), and which extend at right angles relative to the piston rods, and that the beams are connected to the main gearwheels (17 18) by shaft pins (21, 22, 22, 23) which move in pairs in guides (24) provided in the longitudinal direction of the respective beam.
Abstract: A lens frame is contained in a lower lens barrel and moves in a direction of an optical axis as guided by a guide shaft. An adjusting lever is provided with a lever body having a bearing for supporting the lower end of the guide shaft and an opening into which an adjusting pin is inserted, and a holding portion extended from near the opening of the lever body to outside the lower lens barrel. A length between an edge of the holding portion and a center of the opening is longer than the length between the center of the opening and a center of the bearing. The lever moves around the adjusting pin in a plane orthogonal to the optical axis to adjust the position of the guide shaft.
Abstract: A data input/output control method and apparatus in an input/output subsystem are provided. The data input/output control method, in a system for inputting/outputting data to/from a disk sector according to an input/output command provided from a disk driver, includes: extracting the input/output commands for inputting/outputting the data to/from disk sector from the disk driver and generating a set of input/output commands; analyzing the load feature of the input/output command based on the set of input/output commands; determining whether the load of the input/output command corresponds to a multimedia application; and controlling the data which is input/output to/from the disk to correspond to the multimedia application according to the determination result.
Abstract: A printer-control apparatus, a printer-control method, and a printer according to the invention sequentially record a relative position of a printing medium specified from an accumulated carried amount of the printing medium and/or driving speed of a paper-feed motor for driving a printing medium carrying mechanism for carrying the printing medium for a period longer than reaction delay time at every time interval shorter than the reaction delay time as a time difference between a time when a front edge or a rear edge of the printing medium reaches an initial position of a swing pin of a mechanical paper detection sensor which detects the front edge and/or the rear edge of the printing medium by swinging operation of the swing pin and a time when the front or rear edge of the printing medium is detected.
Abstract: A screenings washer having a hopper, a grinder downstream of the hopper, and a washer downstream of the grinder. The washer includes an auger rotor that receives the screenings ground by the grinder, a spray wash system that sprays a wash fluid directly onto a portion of said auger rotor and the ground screenings, a perforated trough, and tubular casing directly coupled to the discharge end of said auger rotor and having a severe bend proximate to the discharge end of said auger rotor.
