Abstract: A compressor includes a first throttle portion that receives a refrigerant at an intermediate pressure from an injection pipe of a refrigerant circuit, an enlarged flow path portion that receives the refrigerant from the first throttle portion, a second throttle portion that receives the refrigerant from the enlarged flow path portion, and a compression element. The compression element includes a compression chamber that receives the refrigerant from the second throttle portion. The first throttle portion has a flow path cross-sectional area that is narrower than both a flow path cross-sectional area of the injection pipe and a flow path cross-sectional area of the enlarged flow path portion. The second throttle portion has a flow path cross-sectional area that is narrower than the flow path cross-sectional area of the enlarged flow path portion.

Abstract: An image comparison section provided in a monitoring system compares current image data with past image data acquired in at least one preceding cycle when a vehicle is determined to be in motion on the basis of an output signal input from a motion sensing section. On the basis of a comparison result, the image comparison section determines whether or not a camera or an image processing section broke down. When there is a failure, the image comparison section outputs an output signal reporting the failure to the image processing section. Upon receipt of the output signal, the image processing section performs image processing intended for the event of a failure, and transmits failure information while superimposing the failure information on an image signal, thereby changing a display device to a monochrome display or an alarm display.

Abstract: A control device for a vehicle flasher assembly configured with an informing circuit to inform a disconnection state of any one of main flashers out of vehicle flasher assembly including a left front part main flasher disposed at a left position on a front part of a motor vehicle, a left rear part main flasher disposed at the left position on a rear part of the vehicle, a left side part sub-flasher disposed at the left position on a side part of the vehicle, a right front part main flasher disposed at a right position on the front part of the vehicle, a right rear part main flasher disposed at the right position on the rear part of the vehicle, and a right side part sub-flasher disposed at the right position on the side part of the vehicle.

Abstract: A first engaging hole and a second engaging hole are formed in a fan-shaped standing portion which is fixed to a vehicle body frame and concentrically constructed with respect to a tilt direction of a the driver's cabin with a hinge shaft as a center of tilting. The first and second engaging holes respectively correspond to a tilt down position and a tilt up position of the driver's cabin. The standing portion is inserted into an actuating member fixed to a driver's cabin frame, and a locking pin urged by a spring is slidably disposed to the actuating member. Since the locking pin slides on a surface of the standing portion, the locking pin can be automatically engaged with the first or second engaging hole.

Abstract: The lift arm of a skid steer loader according to the present invention has a simple structure. A pair of left and right lift arms each has a first arm portion and a second arm portion. The first arm portion is made as an elongated member from components made from plate metal or the like, and its base end is rotatably fitted to a support portion which projects upwards at a rear portion of the main body of the loader. In this second arm portion, a connection portion, an attachment fitting portion, a horizontal load bearing portion, and an actuator fitting portion and so on are integrally formed as one member from cast metal. Furthermore, a hollow portion is formed in the interior of this second arm portion, extending from an approximately intermediate portion thereof to its base end.

Abstract: An image processing unit 103 detects motion information of an image photographed by an image sensor 102 and sends the motion information to a control unit 14. The control unit 104 generates an angle control signal according to the motion information of the image and sends the angle control signal to a signal transmitting unit 105. The signal transmitting unit 105 transmits the angle control signal to an image content distribution server 110 over a network 120. A signal receiving unit 106 receives an image signal from the image distribution server 110 over the network 120. A display 101 displays image information received by the signal receiving unit 106.

Abstract: An insulating film (2) is formed on a semiconductor substrate (1) formed of silicon carbide. A contact hole (3) is formed in the insulating film (2) to expose a part of the upper surface of the semiconductor substrate (1). Then, nickel (Ni) (4?) is formed above the semiconductor substrate (1). Subsequently, the semiconductor substrate (1) is subjected to a heat treatment, whereby the contact portion of nickel (4?) chemically bonds with the semiconductor substrate (1) to become an alloy layer (4) of silicon carbide and nickel. Nickel (4?) on the insulating film (2) is selectively removed by etching liquid for dissolving the nickel.

Abstract: A work vehicle is provided that permits easy routine daily inspection services of a rear mounted engine in the vehicle. The vehicle has a cab covering a rear engine compartment. The cab is pivotally mounted on the frame of the vehicle. An engine hood is in turn pivotally mounted on the cab and covers the engine in the engine compartment. Accordingly, the hood can be pivoted or rotated to expose the engine for routine daily maintenance while the cab and the engine hood can be pivoted or rotated to expose the entire engine compartment for periodic heavy duty maintenance.
