Abstract: There are provided a capture notification system, a capture notification method, a program, an information storage medium, and an information processing device for allowing a user executing a program to become aware of another user capturing an image indicating content of execution of the program. A capture request receiving section (38) receives a capture request of an image indicating content of execution of a program from a capture requesting user requesting capture of the image. A notifying section (40) notifies a capture object user that the image is to be captured in response to the receipt of the capture request.

Abstract: An information processing device for allowing a user to immediately understand that a beginning or end element object is displayed on a screen is provided. The device includes a display unit for displaying a portion of a display object, in which a plurality of element objects are arranged, in a display area, a first scrolling unit for scrolling the display object in a first direction in response to an operation of a user, a second scrolling unit for scrolling the display object in a second direction that is opposite to the first direction, and a determination unit for determining whether or not to scroll the display object in the second direction based on a position of the display area and a position corresponding to the plurality of element objects.

Abstract: An end part of a piston on a front edge side is formed so as to have a crowning of a 1.2-order to 2.5-order curve where a length is 10% or more and 80% or less of a length of a cylindrical part and a height is 10% or more and 160% or less of a clearance. An end part of a cylinder block on a front edge side is formed so as to have a crowning of a 1.2-order to 2.5-order curve where a length is 8% or more and 60% or less of the length of a cylindrical part and a height is 12% or more and 125% or less of the clearance.

Abstract: A filler plug is configured such that: a head portion is formed on an upper end of an external thread; a sealing portion formed at the head portion strongly contacts a funnel-shaped inclined inner peripheral surface formed at one end of an internal thread of a hydraulic device oil passage by tightening the external thread with respect to the internal thread; an upper peripheral surface of the sealing portion is tapered; a circular constricted portion is formed between the sealing portion and the upper end of the external thread; and a dimensionless value of a head portion height H1 from an upper surface of the head portion to the sealing portion, that is, a dimensionless value obtained by dividing the head portion height H1 by a nominal designation value of the external thread portion, ranges from 0.4 to 0.7.

Abstract: A swash plate type hydraulic rotating machine includes: a rotating shaft; a valve plate; a swash plate; a cylinder block on the outside of the rotating shaft slidingly contacting the valve plate; cylinders provided in the cylinder block having axially movable pistons therein; shoes on a distal end of respective pistons; an annular keep plate between the swash plate and the cylinder block supporting the shoes having a plain bearing within the inner periphery of the keep plate, the plain bearing supporting the keep plate to push the keep plate toward the swash plate side; and set springs biasing the plain bearing and the cylinder block toward the opposite sides in the axial direction. The swash plate type hydraulic rotating machine is configured such that, when in an assembled state, a gap in the axial direction between the cylinder block and the plain bearing is 0 or a fine gap.

Abstract: A squeeze film damper for a bearing and a vibration damping mechanism capable of damping the vibration of a rolling bearing are provided. The squeeze film damper is small in construction and can be easily made by mass production. The vibration damping mechanism is capable of damping both radial and axial vibrations. A bearing housing 15 is provided with a bearing holding bore 16 of a diameter greater than the outside diameter of the outer ring 14 of a bearing, and an oil hole 19 through which oil is supplied into the bearing holding bore 16. A vibration damping mechanism 1 is formed by inserting a thin, flat sheet 17 provided with slits into an annular space formed between the inner wall of the bearing holding bore 16 and the outside surface of a bearing held in the bearing holding bore 16 so as to surround the bearing. Parts of the thin, flat sheet extending between the adjacent slits serve as elastic beams. The elastic beams center the bearing and support the centered bearing elastically.
