An connecting structure of an electromagnetic valve includes: a first connecting structure body (60) that prohibits a relative movement between a hydraulic pressure circuit body (10) and an electromagnetic valve (20) in an axis line direction; a second connecting structure body (70) that prohibits a relative movement therebetween in a plane orthogonal to the axis line direction; a third connecting structure body (80) that prohibits a relative rotation about the axis therebetween; and a connection body (50) that is prohibited from moving relatively to the hydraulic pressure circuit body, wherein the first connecting structure body includes a first target connection tool (61) that is provided in an accommodation body and a first connection tool (62) that locks the first target connection tool in the axis line direction at a wall portion constituting an accommodation space (13).

The present invention provides a controller for a pendulum type wave-power generating apparatus. Electric power produced by wave-power generation has been pointed out as being of low efficiency and more expensive than wind-power generation. To overcome the above problems, the present invention uses resonance and impedance matching of the sea waves, thus making it possible to markedly enhance the efficiency of wave-power generation. The present invention does not use a wave-height meter which is generally expensive and controls the generating apparatus in response to variation of the conditions of the sea, thus automatically maintaining the resonance and impedance matching operation, thereby making high-efficiency operation possible. As a result, the cost of the wave-power generation can be reduced, so that the wave-power generation can be widely commercialized.

The present invention relates to a mast column 15 for a multi-stage lift truck, comprising a base rail 60 having, in a cross-sectional view, a substantially C-shaped cross section formed by a forward flange portion 155, a rearward flange portion 160, and a web portion 165 connecting the forward and rearward flange portions 155, 160, and an inner rail 125 nested with the base rail 60, the inner rail 125 having, in a cross-sectional view, a substantially C-shaped cross section formed by an inner forward flange portion 190 located proximate the forward flange portion 155 of the base rail 60, an inner rearward flange portion 195 located proximate the rearward flange portion 160 of the base rail 60, an inner web portion 200 connecting the inner forward flange portion 190 with the inner rearward flange portion 195 of the inner rail 125, and a projecting portion 205 extending toward the base rail 60. The invention further relates to a mast for a multi-stage lift truck as well as a multi-stage lift truck using such a mast column.

Disclosed herein is a hydraulic actuator system comprising a servoactuator including a hydraulic actuator (10) and a control valve (20), wherein the supply of hydraulic fluid to the servoactuator from a fluid supply (32) is adjustable through a control system (40) based on feedback information relating to the servoactuator. The hydraulic actuator system may e.g. be used for controlling blade pitch in a variable pitch propeller system such as may be found on a turboprop aircraft or a ship.

Disclosed is a hydraulic control valve assembly of automatic steering system for agricultural machine including a proportional directional valve (3). A balancing valve (1) is arranged between the proportional directional valve (3) and the steering cylinder. A first shuttle valve (2) is arranged between the proportional directional valve (3) and the balancing valve (1). The first shuttle valve (2) is positioned on one side of the proportional directional valve (3). An overflow valve (4) is positioned on another side of the proportional directional valve (3). The overflow valve (4) is connected to a second shuttle valve (6) and a logic valve (5) respectively. The hydraulic control valve assembly has a large control power, a rapid response, and is more suitable for the autonomous navigation operation of agricultural machine. Moreover, the system saves more energy, such that the autonomous navigation operation of agricultural machine is more stable.
