Abstract: A railcar that allows a first end beam to move toward a second end beam when an intended load is input is provided. A railcar includes a fuse member that couples a first end beam to a second end beam along a car longitudinal direction, and the fuse member buckles when a load received in collision exceeds a predetermined value to allow the first end beam to move toward the second end beam, thus ensuring reduction of variation of the load that allows the first end beam to move toward the second end beam. Consequently, when the intended load is input, the first end beam is allowed to move toward the second end beam.

Abstract: According to a railcar, a fuse member that couples a first end beam to a second end beam along a car longitudinal direction is formed as a channel material with an approximately U-shaped cross-section, including a web disposed to extend along the car longitudinal direction and a pair of flanges disposed upright from both end portions of this web. Accordingly, when a load received in collision exceeds a predetermined value, the fuse member buckles to allow the first end beam to move toward the second end beam to ensure reducing variation of the load that allows the first end beam to move toward the second end beam. Consequently, when the intended load is input, the first end beam is allowed to move toward the second end beam.

Abstract: According to a railcar, a low-floor underframe includes side beams to which side bodyshells are coupled, a high-floor underframe includes a center sill disposed to extend in a car longitudinal direction at a center in a car width direction and a body bolster coupled to this center sill and to be an installation portion of a bogie, and the body bolster is coupled to the side beam by a coupling member. Thus, the car end compression load input to the high-floor underframe can be directly transmitted from the center sill and the body bolster to the side beams via the coupling member. This can disperse the car end compression load on the side bodyshells to ensure the car strength against the car end compression load.

Abstract: An imaging device with low power consumption is provided. The pixel of the imaging device includes first and second photoelectric conversion elements, and first to fifth transistors. A cathode of the first photoelectric conversion element is electrically connected to the first transistor. An anode of a second photoelectric conversion element is electrically connected to the second transistor. Imaging data of a reference frame is obtained using the first photoelectric conversion element, and then imaging data of a difference detection frame is obtained using the second photoelectric conversion element. After the imaging data of the difference detection frame is obtained, a first potential that is a potential of a signal output from the pixel and a second potential that is a reference potential are compared. Whether or not there is a difference between the imaging data of the reference frame and the imaging data of the difference detection frame is determined using the first potential and the second potential.

Abstract: A rolling stock includes: a pair of left and right post members provided upright on inner sides of left and right end portions of an end beam of an underframe, the end beam joined to a lower portion of a cab end structure; a recess portion open frontward, the recess portion formed in a front portion of the end beam between the pair of post members; and an impact absorbing member disposed between a bottom face of the recess portion and an inner face of the outside plate. The recess portion has such a size that the impact absorbing member is accommodated within the recess portion after being compressively deformed. Since the impact absorbing member is disposed on an inner side of the outside plate, the impact absorbing member is not exposed to the outside of the car body, and thus does not impair the design of the car body.

The wave-power generator includes a weight that is installed in a floating body via a spring and that linearly reciprocates in response to a fluctuation of a water surface and a generator that generates power by being driven based on the linear reciprocating motion of the weight. An additional-mass body for adding a mass to the mass of the weight is further included.

Abstract: Gases are smoothly and automatically switched when using two gas supply sources, that is, an air pump and a carbon dioxide gas cylinder. By using a gas supply flow rate adjusting unit, a carbon dioxide gas is supplied to an endoscope, and a gas using a carbon dioxide gas and water are delivered. When the remaining amount of the carbon dioxide gas of the cylinder is detected and the detected pressure of the carbon dioxide gas becomes less than a predetermined value, the air pump is rotated to supply pressurized air. The rotation number of the air pump is controlled, and the same amount of pressurized air is supplied as that of the supplied carbon dioxide gas. The switching to the pressurized air is automatically performed. The supply amounts before and after the switching become equal to each other, and a surgical operator does not feel any discomfort.
