The angle of fuel spray at the time of pre-injection is set to a wider angle of spray and the angle of fuel spray at the time of main injection is set to a narrower angle of spray. The pre-injection timing is set so that when fuel spray after the pre-injection is diffused in a cylinder and stratified, the stratified fuel spray is ignited by a rise in the pressure in the cylinder in association with movement of a piston from the bottom dead center to the top dead center. The main injection timing is set so that when the spray stratified by the pre-injection is burned, the fuel spray injected by the main injection passes through the combustion zone while being ignited in the combustion zone, reaches a combustion chamber of the piston, and is burned in the combustion chamber.

An expandable, adjustable inter-body fusion device is presented. The inter-body fusion device can have a first plate, a second plate, and an insert positioned substantially there between the first plate and the second plate. The first plate, the second plate, and the insert define an interior cavity. Moving the insert longitudinally with respect to the first and second plates increases or decreases the distance of the first plate with respect to the second plate, effectively expanding the inter-body fusion device and increasing the volume of the interior cavity. The angle between the first plate and the second plate is selectively adjustable.

A graftless prosthetic stent for treatment of vascular lesions such as aneurysms and arterio-venous fistulas, especially in neurovascular vessels, comprises a continuous helical ribbon formed of a shape-retaining metal having a transition temperature at which the stent expands from its contracted condition to a radially expanded condition, the stent remaining substantially cylindrical in its contracted and expanded conditions. The helical windings have variable width, thickness, number or size of openings, or combinations of these features, which affect the stiffness, rate of expansion at the transition temperature, and the area of vessel wall covered by the stent. A catheter device which includes the stent, and a method of treatment using the stent are also provided.

A balloon catheter having a balloon with a reduced slippage lubricious coating, and a method of performing a medical procedure such as a balloon dilatation procedure in a patient's blood vessel. The second coating (i.e., the balloon coating) is lubricious to facilitate movement of the catheter in the patient's body lumen, yet has sufficiently low lubricity such that the slippage of the inflated balloon from a desired site within the blood vessel is reduced compared to a balloon coated with the first lubricious coating.

A redundant and fail-safe blade system of a wind turbine includes at least one blade pitch drive (20, 21, 22) and at least two power control modules (60, 61, 62, 6′) for controlling the blade pitch drive (20, 21, 22). The power control modules (60, 61, 62, 6′) are connected to the blade pitch drive (20, 21, 22) by a switching unit (10) which allows an alternative connection between the blade pitch drive (20, 21, 22) and any of the power control modules (60, 61, 62, 6′). In operation, the blade pitch drive (20, 21, 22) is controlled by only one of the power control modules (60, 61, 62, 6′). If a malfunction of the currently operating power control module (60, 61, 62, 6′) is detected, switching unit (10) provides a connection to the other power control module (60, 61, 62, 6′) to allow an ongoing operation of the wind turbine without an unplanned or forced shut-down.

An adjustable bed that enables a Gatch mechanism to be operated in an excellent fashion to match the flexing of a care recipient's body, and that is, moreover, useable as a superior low platform bed for care recipients. To this end, a parallel link mechanism having a pair of perpendicular arms is provided in the adjustable bed as part of a sitting-up mechanism, and by always keeping these arms in a perpendicular position, the sitting-up mechanism is operated with a position removed from the surface of a lower-back board by a prescribed interval as an imaginary rotation center when the bed is driven. This prevents any slippage of the care recipient's body in relation to the platform surface, thereby suppressing the occurrence of bedsores and realizing a natural sitting-up action that takes account of the care recipient's body movement.
