Abstract: A flap gate includes a door body and a flap ancillary part. When the door body is in its down position, a movable end portion of the door body is located forward of a supported end portion. The door body changes its position between the down position and a maximum up position. The flap ancillary part applies tilt-up moment to the door body only when the door body is located in a position between the down position and a first position. The flap ancillary part also applies tilt-down moment to the door body only when the door body is located in a position between the maximum up position and a second position.

The door body changes its position between the down position and a maximum up position. The flap ancillary part applies tilt-up moment to the door body only when the door body is located in a position between the down position and a first position. The flap ancillary part also applies tilt-down moment to the door body only when the door body is located in a position between the maximum up position and a second position. This simplifies the structure of the flap gate that can speedily start to tilt up when water flows in and that can early start to tilt down when the water level has started to drop.

Abstract: A combustion system includes a combustor having staging blocks and flashback detection units configured to detect flashbacks occurring in the staging blocks, and a combustion control device configured to stop a supply of a fuel for one of the staging blocks in which a flashback occurs based on a detection signal from one of the flashback detection units. The combustion control device includes a staging processing unit configured to instruct to supply the fuel or stop the supply of the fuel for each of the staging blocks based on a staging pattern in which an operating line is specified and a load adjustment unit configured to reduce an amount of load to a level at which the supply of the fuel for the one of the staging blocks is stopped when the detection signal is input from the one of the flashback detection units.

Abstract: A piston pin is provided that includes a pin oil channel to which oil is supplied from the connecting rod. A piston is provided that includes a pin boss, an oil groove formed in a pin bore surface, and a communication oil channel that connects a cooling channel that is provided closer to a combustion chamber than the piston pin and the oil groove to each other. The pin oil channel opens in the outer surface of the piston pin at a point corresponding to the oil groove. In the view of the piston from the direction of the piston pin axis, the oil groove is formed in the pin bore surface at a position closer to a crankcase than a second straight line and is not formed in a part of the pin bore surface that is closer to the combustion chamber than the second straight line.

Abstract: A combustion system (1) includes a combustor (2) having a plurality of staging blocks and flashback detection units (40, 41, . . . ) configured to detect flashbacks occurring in the staging blocks, and a combustion control device (10) configured to stop a fuel for a staging block in which the flashback occurs based on a detection signal from the flashback detection units (40, 41, . . . ). The combustion control device (10) includes a staging processing unit (100) configured to instruct to supply the fuel or stop the fuel supply for each of the staging blocks based on a staging pattern in which an operating line is specified and a load adjustment unit (101) configured to reduce an amount of load to a level at which the fuel supply for the staging block corresponding to the flashback detection unit (40, 41, . . . ) is stopped when the detection signal is input from the flashback detection unit (40, 41, . . . ).

Abstract: A sliding bearing 2 has a sliding surface 2a in sliding contact with an outer peripheral surface of a crankshaft 1 (rotating shaft) and a relief portion 4 formed along a circumferential direction on both axial end portions of the sliding surface 2a and retreated outward in a radial direction from the sliding surface 2a. The relief portion 4 is provided with a flat portion 4a formed on the axial end portion and a tapered portion 4b formed so as to become gradually deeper from the flat portion 4a toward a boundary portion between the relief portion 4 and the sliding surface 2a. A lubricant forms a disturbance or a swirl inside the tapered portion 4b and then, flows along the tapered portion 4b so as to form a high-pressure region W by a flow of the lubricant at a position of the flat portion 4a. A temperature of the lubricant can be rapidly raised and also, leakage of the lubricant can be suppressed.

Abstract: A display method of a plasma display apparatus to which primary color video signals are inputted and which carries out color display by letting phosphors for primary colors emit light is provided. The display method displays the primary color video signals by changing a gray level of an output primary color video signal in accordance with a gray level of an input primary color video signal. When each gray level of the inputted primary color video signals changes from a first value to a second value which is larger than the first value, a gray level of a primary color video signal for a phosphor having the largest influence of luminance saturation properties among the phosphors is increased relative to a gray level of the other primary color video signal.

Abstract: A sliding bearing structure for a shaft member includes: a shaft member; a bearing member rotates relative to the shaft member; an oil supply space to which lubrication is supplied between sliding surfaces of the shaft member and the bearing member; two annular grooves formed in a circumferential direction in an inner peripheral surface of the bearing member; and two annular seal members formed as separate pieces from the shaft member and the bearing member, and arranged in the annular grooves between the shaft member and the bearing member. Each annular seal member is formed in plural, and is made of material having a thermal expansion coefficient such that an inside diameter of the annular seal member is smaller than an inside diameter of the bearing member at a low temperature, and is the same as or larger than the inside diameter of the bearing member at a high temperature.
