Abstract: Under a reduced-pressure environment, stopping at will liquid that flows out from a nozzle tip, or dispensing liquid with the level of energy at which it will not splatter has proven difficult. To address such difficulties, parameters including nozzle bore, and surface tension and viscosity of, and delivery pressure on, a liquid are selected so that the surface tension that acts on the liquid when flowing out from the nozzle tip will be greater than the momentum of the liquid. By dispensing liquid under such conditions, outflow of the liquid is reliably controlled, and rapid infusion work is realized.

Abstract: Method of charging dynamic-pressure bearing device with lubricating fluid. Preparatorily, lubricating fluid is put into a vacuum chamber and the chamber is vacuum-evacuated to subject the lubricating fluid to a degassing process. An appropriate quantity of fluid is dispensed in one end of the bearing gap, with the bearing device having been placed in a reduced-pressure ambient. In carrying out the dispensation, the pressure of the ambient is adjusted so as to be higher than the pressure during the degassing process. The method in this way prevents the lubricating fluid from frothing when it is being dispensed, and makes it possible to charge dynamic-pressure bearing devices with lubricating fluid without soiling the bearing-device surfaces with splashes or other contaminants.

Abstract: In a controllable damping force shock absorber, a piston member connected to a piston rod is disposed in a cylinder in which a magnetic fluid is contained. A disc valve having an extension-stroke pressure-receiving portion and a compression-stroke pressure-receiving portion is provided in the piston member, and a pilot chamber is formed on a rear side of the disc valve.

The controller controls the movement of the moving device from a position where the detector has detected the end of the folded portion to the cutting position so that a size of a booklet after being cut is kept constant for each of sheet sizes.

Abstract: Infusion apparatus for dispensing lubricating fluid into a dynamic-pressure bearing device. Apparatus is made up of: a lubricating-fluid tank whose interior is filled partway with lubricating fluid; a vacuum chamber for placing the bearing device under a reduced-pressure environment; a nozzle for streaming the lubricating fluid into the bearing device; and a vacuum-evacuation system for evacuating and repressurizing the interior of the lubricating-fluid tank and of the vacuum chamber. Air dissolved into the lubricating fluid is eliminated by pumping-down the hollow, fluid-absent portion of the lubricating-fluid tank. Then repressurizing the hollow portion enables pressure to be applied to the lubricating fluid to force it out through the nozzle tip. The vacuum chamber interior may be pumped down to the optimum pressure for charging the bearing device with the lubricating fluid.

Abstract: In a suspension control system according to the present invention, a sky-hook command signal B obtained from velocity data obtained by integrating a sprung mass acceleration ?u from a sprung mass acceleration sensor 9u and an unsprung mass vibration damping command signal C obtained on the basis of an unsprung mass acceleration ?d detected by an unsprung mass acceleration sensor 9d are added together to obtain a control signal A for a damping characteristic inverting type shock absorber 6. The control signal A reflects the unsprung mass acceleration ?d that leads in phase by 90° the piston speed. Accordingly, it is possible to compensate for a response delay due to an actuator 11, etc.

Abstract: The piston 10 is constituted so as to rotate relative to the first cylinder 8 while moving relative to the first cylinder 8 in the axial direction when fluid is supplied to and discharged from the interior of the first cylinder 8, and the piston 16 is constituted to be incapable of rotation relative to the second cylinder 9, but capable of movement relative to the second cylinder 9 in the axial direction. Hence when fluid is supplied to and discharged from the interior of the first cylinder 8, the piston 10 is caused to rotate relative to the first cylinder 8 while moving relative to the first cylinder 8 in the axial direction, and the piston 16 is caused to move relative to the second cylinder 9 in the axial direction but prevented from rotating relative to the second cylinder 9. As a result, torsional elasticity is generated in shaft portions 4a and 5a.

Upon supplying oil through a pipe that communicates between a first vacuum chamber and a second vacuum chamber upon filling the oil, stored in the first vacuum chamber that is under a reduced pressure environment having a pressure lower than that in the surrounding environment, to the fluid dynamic pressure bearing held in the second vacuum chamber that is similarly under a reduced pressure environment having a pressure lower than that in the surrounding environment, the pressure in the first vacuum chamber is reduced to be lower than the pressure in the second vacuum chamber at the time of filling lubricating fluid.

Abstract: In a controllable damping force shock absorber, a piston member connected to a piston rod is fittingly disposed in a cylinder in which a magnetic fluid is sealably contained. A disc valve having an extension-stroke pressure-receiving portion and a compression-stroke pressure-receiving portion is provided in the piston member, and a pilot chamber is formed on a rear side of the disc valve. A coil is provided adjacent to passages communicated with the pilot chamber. By energizing the coil for excitation, a magnetic field that acts on the magnetic fluid flowing through the passages is generated, thus changing the viscosity of the magnetic fluid to thereby control a damping force. A valve-opening pressure of the disc valve is controlled according to the pressure in the pilot chamber, in such a way that the magnetic fluid exposed to the magnetic field can be flowed at a low flow rate, thus achieving low power consumption.
