An ink replenish adjunctive device is used to replenish an ink to an ink tank that includes an ink inlet member having a flow path in an axial direction. The ink replenish adjunctive device includes a connection portion having an end that is connectable to the ink inlet member in a liquid-tight state, and an ink inflow portion that is configured to allow the ink flow toward the connection portion.

Apparatus and method for casting metal strip by controlling the distance between the confining side plates confining the casting pool and the outer nozzle ends of discrete nozzle pieces of the delivery nozzle delivering the molten melt. The nozzle pieces defining the outer nozzle ends may be moved and control separately from the position of the confining plates, or with the position of the confining plates, by a nozzle delivery drive. The distance between the outer nozzle ends and the confining plates may be set before casting and maintained during casting with wear and thermal expansion of the confining plates, nozzle pieces, or both, or varied during the casting operation, to inhibit the formation of skulls in the casting pool and the formation of “snake eggs” in the cast strip.

In a steam-water separator, a swirl vane (52) is provided inside a riser (51), an annular downcomer space (54) is formed by providing a downcomer barrel (53) outside the riser (51), a deck plate (55) is arranged above the riser (51) and the downcomer barrel (53) with a predetermined space therefrom, an orifice (56) and vents (57) are formed, and aperture ratios of plural slits (58a, 58b, 58c, and 58d) formed on the riser (51) are set at from 30% to 70%. Accordingly, the steam and the water is appropriately separated, and the separated steam is reliably discharged upward from the orifice while the separated water is allowed to reliably flow down through the downcomer space, thereby enhancing steam-water separating efficiency.

The present invention is TAH system for auto-regulating blood flow and maintaining the asymmetric pressure balance in the mammalian cardiovascular system by decreasing the resistance in blood flow and minimizing the pressure gradients to exploit the in-flow pressure sensitivities of continuous flow pumps. The system further includes laminar flow generating manifolds connected to the atrium at one end and attached to pumps linked to the great vessels at the other, such that the in-let flow sensitivities of the pumps are maximized to auto-regulate blood flow, providing adequate pulmonary and systemic arterial flow to support normal metabolism and end-organ function and maintain the appropriate asymmetric physiologic pressure balance between the systemic and pulmonary systems of the mammalian cardiovascular system.

A fuel cell system configured to generate an electric power by supplying an anode gas and a cathode gas to a fuel cell includes: a connection line configured to connect the fuel cell to an electric load; a converter connected to the connection line and a battery, the converter being configured to adjust a voltage of the connection line; a target output current calculating unit configured to calculate a target output current of the fuel cell in accordance with a load of the electric load; a converter control unit configured to carry out a switching control for the converter in accordance with the target output current; and a flow rate control unit configured to control a flow rate of the cathode gas to be supplied to the fuel cell in accordance with the target output current. The target output current calculating unit sets up an upper limit to the target output current on the basis of a generated electric power of the fuel cell and a guaranteed minimum voltage of the connection line for ensuring performance of the fuel cell and the electric load.

The invention mainly relates to a system for suppressing forced vibration of a centrifugal impeller. The system comprises a centrifugal compressor. A housing cover plate is disposed in front of an impeller of the centrifugal compressor and forms an air suction channel. An annular air accumulation chamber is disposed on an external peripheral surface of the air suction channel, and provided with a jet air stream inlet communicating with an air inlet channel. A plurality of jet holes communicating with the air accumulation chamber and used for jetting a jet air stream to a position in front of the impeller to inhibit the vibration of the impeller are uniformly formed in the air suction channel in a peripheral direction with each jet hole axially facing the impeller. The system for suppressing forced vibration of a centrifugal impeller is provided with the annular air accumulation chamber on the housing cover plate; a jet air stream enters the annular air accumulation chamber via the jet air stream inlet and then is uniformly jetted via the jet holes to a region in front of the impeller; the jet air stream forms a local flow field for blocking the vibration of the impeller under appropriate pressure and at an appropriate angle of attack, thereby achieving an aerodynamic damping effect and allowing effective suppression of the fatigue damage of the centrifugal impeller caused by air stream excitation under complicated operating conditions.
