20120025015 | AIRCRAFT ACTUATOR CONTROL APPARATUS - A plurality of hydraulically operated actuators that drive a control surface and a plurality of control systems that respectively control the operation of the actuators are included. Each of the control systems includes a control valve, a state switching valve and a test orifice circuit. The test orifice circuit includes a test orifice used for testing the performance of an orifice. The state switching valve is provided such that its position can be switched between an actuator connection position, a damping position and a test orifice position. | 02-02-2012 |
20120075373 | LIQUID DISCHARGER AND IMAGE FORMING APPARATUS HAVING THE SAME - A liquid discharger is provided, which includes a gap adjustor that moves a first liquid discharge head between a first position and a second position where a gap between the first liquid discharge head and a sheet is smaller than when the first liquid discharge head is in the first position, and a controller configured to, when determining that second liquid is left enough to form an image and that a quality level stored in a storage unit is equal to or more than a predetermined level, control the gap adjustor to place the first liquid discharge head in the second position, control the first liquid discharge head to discharge the first liquid, and forbid a second liquid discharge head to discharge the second liquid. | 03-29-2012 |
20120162693 | IMAGE RECORDING DEVICE AND COMPUTER ACCESSIBLE STORAGE STORING PROGRAM THEREFOR - An image recording device is provided with a first memory which is a volatile memory, a second memory, an input unit through which authentication information is input, an authentication judging unit. The recording unit is controlled to print an image on the printing sheet based on the drive data, which is converted from the image data stored in the first memory or the second memory and is stored in the first memory or the second memory. The drive data or the image data is stored in each of the first memory and the second memory is transmitted therebetween. The image recording device further includes a restricting unit capable of restricting power supply to the converting unit and the first memory in a sleep mode. | 06-28-2012 |
20120181382 | AIRCRAFT ACTUATOR - A plurality of tandem actuators including piston rods in each of which two pistons are provided in series are disposed in parallel. A rod end portion couples the piston rods of the plurality of tandem actuators on the outside of case portions and can be rotatably linked to a control surface. For each of the tandem actuators, first hydraulic chambers on the side opposite to the rod end portion side are in communication with each other in the two piston movement areas, respectively, and second hydraulic chambers on the rod end portion side are in communication with each other in the two pistons areas, respectively. | 07-19-2012 |
20120305701 | AIRCRAFT CONTROL SURFACE DRIVE MECHANISM - An actuator includes a plurality of cylinder units each including a cylinder and a rod, and is pivotably attached, at a first end thereof, to a control surface. A reaction link is pivotably attached, at a first end thereof, to a fulcrum shaft rotatably supporting the control surface. The reaction link is pivotably attached, at a second end thereof, to a second end of the actuator between the plurality of cylinder units. | 12-06-2012 |
20130047838 | FLUID ACTUATOR - A fluid is supplied and discharged to and from a cylinder. A body portion is fixed to a fixed-side structure, and the cylinder is provided integrally with the body portion. A piston defines a cylinder chamber inside the cylinder and slides on an inner wall of the cylinder. A rod is provided integrally with the piston and is displaced so as to extend from and contract into the cylinder. A link member is installed parallel to the axial direction of the cylinder or installed so as to extend obliquely to a direction parallel to the axial direction of the cylinder, and a first end of the link member is pivotably connected to a movable-side structure. A connecting member is fixed to the rod, and a second end of the link member is pivotably connected to the connecting member. | 02-28-2013 |
20130104729 | ROTARY ACTUATOR | 05-02-2013 |
20130133513 | ROTARY ACTUATOR - A cylinder is installed within a case, and an output shaft and an arm that is integrated thereto and extends in a radial direction are installed within the cylinder. A piston extending in an arc slides and is displaced in a circumferential direction of the cylinder within the cylinder. One end portion of the piston is rotatably connected to the arm. The cylinder is internally provided with a first pressure chamber in which the arm is housed and a second pressure chamber in which the other end portion of the arm is slidably installed. A pressure medium is fed into one of the first and second pressure chambers and discharged from the other, and the output shaft pivots in a rotational direction. | 05-30-2013 |
20130247754 | ROTARY ACTUATOR - An output shaft and arms are installed inside a cylinder. Pistons that are formed in an arc shape and rotatably connected to the arms slide and are displaced in the circumferential direction of the cylinder inside the cylinder. Inside the cylinder, a first pressure chamber on the arm side and second pressure chambers on the piston head portion side are provided. Third pressure chambers are provided on both sides of the cylinder. A pressure medium is supplied to one of the first pressure chamber and the second pressure chamber and discharged from the other, and the output shaft pivots in a rotational direction. When the pressure medium is supplied to the second pressure chambers, the pressure medium is also supplied to the third pressure chambers. | 09-26-2013 |
