A MOS device having corner spacers and a method for forming the same are provided. The method includes forming a gate structure overlying a substrate, forming a first dielectric layer over the gate structure and the substrate, forming a second dielectric layer on the first dielectric layer, forming a third dielectric layer on the second dielectric layer, and etching the first, the second and the third dielectric layers using the third dielectric layer as a mask. The remaining first and second dielectric layers have an L-shape. The method further includes implanting source/drain regions, removing remaining portions of the third dielectric layer, blanket forming a fourth dielectric layer, etching the fourth dielectric layer, siliciding exposed source/drain regions, and forming a contact etch stop layer. The remaining portion of the fourth dielectric layer forms corner spacers.

The present invention relates to a rubber crawler including: a joint formed by joining together opposite ends of a crawler body comprising an elastic member shaped like a belt having the opposite ends; and lugs projected at predetermined space intervals along a longitudinal direction of the belt and arranged on an outer circumferential surface of the crawler body. The joint is disposed on the outer circumferential surface of the crawler body, as located in a ground non-engaging portion and at different positions with respect to the longitudinal direction of the belt, the ground non-engaging portion defining an area excluding the lugs. In this way, stress acting on the joint is distributed or reduced.

The invention is a method and apparatus for initiating multiple azimuth controlled vertical hydraulic fractures in unconsolidated and weakly cemented sediments from a single bore hole to control the fracture initiation and propagation of hydraulic fractures at differing azimuths. The multiple azimuth vertical fractures enable greater yield and increased recovery of petroleum fluids from the formation. An injection casing with multiple fracture initiation sections is inserted and grouted into a bore hole. A fracture fluid carrying a proppant is injected into the injection casing and opens fracture initiation sections to dilate the formation in a direction orthogonal to the first fracture azimuth plane. Following completion of the first fracture injection, the fracture fluid is injected into the injection casing and opens a set of second and subsequent fracture initiation sections dilating the formation and initiating and propagating a second and subsequent vertical hydraulic fractures at different azimuths to the first and subsequent earlier installed fractures. The injection casing initiation sections remains open after fracturing providing direct hydraulic connection between the production well bore, the permeable proppant filled fractures and the formation.

The invention discloses a variable pitch system for an offshore high-power wind driven generator group and a control method for the variable pitch system. The system comprises independent variable pitch driving systems on each blade, a variable pitch control system, a limit switch, an angular coder and a sliding ring, wherein the variable pitch driving systems are arranged in a hub on the front part of a cabin; the communication and the motive power of the variable pitch driving systems are realized through the sliding ring connected with the main control system in the cabin; and the variable pitch control system is used for allocating instructions from the main control system in the cabin to drivers and feeding back related signals detected by the angular coder, a rotation coder, the limit switch and a blade root sensor to the main control system in real time. In the variable pitch system, the force bearing acceleration sensor is arranged at a blade root and is used for detecting different applied forces of blades at different positions and feeding back to the variable pitch control system, and the variable pitch control system is used for sending a corresponding instruction to the driving systems, so that the size of a pitch angle is separately corrected, and the variable pitch system is completely independent.

The invention relates to split-chamber pressure exchangers. Split-chamber pressure exchangers are characterized in that the pressure exchange chambers and the pistons thereof are split in two. Each fluid passes through the corresponding chamber thereof, such that said fluids cannot be mixed. The cross sections of the chambers can be varied in order to vary the transmitted pressure. The reverse line operation can be established and synchronized using a U-shaped tube with telescopic sides and a fixed base filled with fluid or diametrically opposed curved lines, and multiple arrangements can be used. Split-chamber pressure exchangers can be used as surface or well pumping systems and the pumping fluid used can differ from the fluid to be pumped. Different levels of any material can be exploited at any storage site using a chamber with elastic walls filled with fluid and attached to the bottom. Electric power can be generated by centrifuging the pre-pumped fluid.

The invention relates to a brake lining carrier plate 1 to hold a friction lining, especially for installation into a vehicle brake system, with holding structures 15, 16 for the friction lining arranged in rows 6 on the lining side 2, whereby each holding structure 15, 16 has a protrusion 3 and a depression 4, whereby the protrusion 3 is made when the depression 4 is formed in the surface 5 through the displacement of material. Said protrusion 3 engages with the friction lining. The holding structures 15, 16 in the rows 6 are arranged in such a way that there is a protrusion 10 at the beginning 8 and at the end 9 of each row 6. In one embodiment, the rows 6 run essentially crosswise to the longitudinal axis 7 of the brake lining carrier plate 1.

A convertible piece of upholstered furniture can be converted via motorized conversion aids from a seat function into a bed, by way of any desired number of intermediate stages, and vice versa. All movable parts can be fully stressed by a person during conversion, even when a person is sitting or lying on the piece of furniture. These changes can take place even when the piece is being used by a person, whereby each movable part of the piece of upholstered furniture can be changed by means of a motor drive having a control. The footrest and the seat part are configured so that they can move out of a base frame with their metal fittings. A lever construction arranged on the metal fitting of the footrest and a motor drive adjusts the height and angle of the footrest and moves the piece of furniture to the various positions.
