An X-ray imaging apparatus is disposed with an imaging table that includes an imaging surface with which a breast of an examinee in an upright posture is brought into contact and handles that are disposed higher than the imaging surface during craniocaudal imaging. Grip portions of the handles slant so as to gradually become closer to a chest wall contacting portion as the grip portions approach the imaging surface. Thus, when an examinee is made to grasp the handles, the posture of the examinee can be made more natural.

In an auto-tensioner, a damping device is used to control a fluid communication between a first fluid chamber and a second chamber for adjusting an engagement of an idler pulley with a belt-shaped power transmission member in such a manner that when a tension thereof is decreased, a quick propulsive movement of the idler pulley to the belt-shaped power transmission member is allowed by the first urging member, while when the tension is increased, the idler pulley is retracted gradually from the belt-shaped power transmission member by a registration of the belt-shaped power transmission member.

Stabilizer device for motor vehicles including a torsion bar, an actuator having a piston and two cylinder chambers on both sides of piston, a first and a second fluid passages for connecting said two cylinder chambers, respectively, a solenoid changeover valve provided in first fluid passage. A actuator has two openings for communicating with each end of first fluid passage within an area on which piston may not slidably contact. A plate member and a centering spring are provided within each of cylinder chambers in such a manner that each of plate members is to come in contact with a bottom surface of cylinder slightly by virtue of resilience of centering spring when piston is positioned in a neutral position. An opening is provided in each of bottom surface of cylinder chambers within an area on which plate member is to come in contact therewith. Each of openings is communicated with second fluid passage and a check valve may be mounted in each of openings.Relative movement of torsion bar with a body portion of the vehicle resulted from up-and-down motion of wheels is transmitted to piston through a piston rod. During changeover valve allows flow of fluid flowing first fluid passage between cylinder chambers, anti-roll, anti-dive and anti-squat effects of torsion bar are made ineffective. When changeover valve prohibits flow of fluid in first fluid passage, fluid is trapped in both cylinder chambers, therefore, anti-roll or anti-dive and anti-squat effects of torsion bar are made effective. Fluid is allowed to flow from one cylinder chamber to another cylinder chamber through second fluid passage, then finally piston is positioned at neutral position.

An automatic hydraulic tensioner according to the present invention is provided with a communication mechanism for allowing a space radially inside a plunger-side end wire portion of a coil spring to communicate with a small clearance between the plunger and a cylinder. This automatic hydraulic tensioner thus succeeds, with a simple structure, in preventing bubbles from remaining within a pressure chamber and appropriately maintaining the tension applied to a power transmitting means such as a belt, a chain or the like.

A digital still camera is provided with a freely rotatably dial. The camera has a liquid crystal display screen provided on its back and the screen displays film borders. A thumbnail image corresponding to main image data that has been recorded on a memory card is displayed in a thumbnail image border within the film borders. By rotating the dial, the film borders are moved so that a desired thumbnail image becomes enclosed by a designating frame. When the thumbnail image is enclosed by the designating frame, the main image is displayed an area. When a blank area is enclosed by the designating frame, the main image data can be recorded on the memory card. Operability is facilitated because recording, playback and designation of a frame to be played back can all be performed in accordance with rotation of the dial.
