A vehicular seating apparatus includes an assistant driver's seat mounted in the interior of a driver cabin of a vehicle and above a service hole on an engine deck raised at a central part of a floor located in the proximity of a driver's seat. The apparatus includes a transverse displacement mechanism for displacing the assistant driver's seat in the transverse direction and a transverse leap-up mechanism for upwardly turning the assistant driver's seat about one end of a seat cushion of the assistant driver's seat located at the side of the driver's seat. A seat frame is provided with a longitudinal slide mechanism for slidably displacing the assistant driver's seat in the longitudinal direction. The apparatus assures that a driver can walk by the side of the assistant driver's seat to reach the rear part of a driver cabin while maintaining good engine service performance. Further, the driver can enjoy excellent driving comfort by virtue of various operations for displacement.

A guide wire for a catheter is disclosed that includes a core wire and a sheath for covering at least the distal end of the core wire. The core wire is formed from a nickel-titanium alloy having a nickel-titanium ratio in the range of 3:2 to 1:1. The core wire is worked in a manner such that in a tensile test wherein the core wire is elongated by at least 5%, the core wire has a recovery percentage of at least 90%. Additionally, elongations in the range of zero and 5% do not cause any stress-induced martensitic transformations and/or austinite reverse transformations. Thus, the load-elongation characteristics of the nickel-titanium alloy are such that the load increasing rate is either proportional or gradually decreasing throughout the elongation range of 0 to 5%.

An axial-position adjustment apparatus is used to adjust the axial position of an arm shaft equipped with paper roll support arms. The arm shaft is supported rotatably and axially movably on a frame in a paper web feed unit and rotated by means of a shaft-rotating apparatus located at one end portion of the arm shaft. The axial-position adjustment apparatus has a moving member including a male screw and connected to the arm shaft in such a manner as to be rotatable and axially immovable in relation to the arm shaft; a guide member having a threaded hole formed therein, the male screw of the moving member being screwed in the threaded hole, and the guide member being provided in such a manner as to be nonrotatable and axially immovable in relation to the frame; and a drive unit for rotating the moving member. The moving member and the guide member are located adjacent to the shaft-rotating apparatus. The drive unit is provided on a support member axially immovably connected to the arm shaft.

A front body construction of a motor vehicle includes a lower dash panel for separating an engine compartment and a cabin and a cowl portion provided on the lower dash panel such that a lower end of a windshield is supported at an upper portion of the cowl portion. The cowl portion includes an upper dash panel attached to an upper end portion of the lower dash panel so as to form a bottom wall of the cowl portion and a front cowl panel attached to an upper face of the upper dash panel so as to form a front wall of the cowl portion. The front cowl panel has, in a lateral direction of a vehicle body, opposite sides and a central portion such that space for an auxiliary unit is provided not only forwards of the front cowl panel in a longitudinal direction of the vehicle body, but also on at least one of the opposite sides of the front cowl panel. At least one of the opposite sides of the front cowl panel is disposed rearwards of the central portion of the front cowl panel in the longitudinal direction of the vehicle body, and the lower end of the front cowl panel is disposed, on at least one of the opposite sides of the front cowl panel, at a location identical with that of or rearwards of an upper end of the lower dash panel in the longitudinal direction of the vehicle body.
摘要:
A cowl box of a vehicle in which a duct passagae through which an air duct of an air conditioner extends in a vertical direction is arranged to support a front windshield in such a fashion that the cowl box and the air duct are superposed as viewed in a transverse direction of a car body. According to this feature, the cowl box can be disposed in an instrument panel without narrowing the width of the cowl box and without enlarging the instrument panel.

A radiation therapy apparatus has a multi-leaf collimator device, a driving gear, a torque wire and a driving unit. The multi-leaf collimator device has a pair of collimator components which respectively comprise a plurality of leaves arranged close to one another such that the leaves face one another across an irradiation axis, and configured to set a desired irradiation field by individually moving the leaves. The driving gear is engaged with a gear tooth of the each leaf, respectively. The torque wire is connected to a shaft center of the driving gear, respectively. The driving unit is configured to drive the driving gears through the torque wire.

A multi-leaf collimator that narrows a radiation field to a predetermined shape is provided with leaf blocks movable in the direction of the radiation field and having pattern images drawn along the direction of movement on a predetermined surface, and detection part acquiring an image of fixed-point via fixed-point observation in the direction of that predetermined surface and for detecting displacement of said leaf blocks based on the arranged locations of the pattern images existing in this image of fixed-point. Moreover, it is provided with detection part acquiring an image of fixed-point via fixed-point observation in the direction of that predetermined surface and for detecting the locations of the leaf blocks based on the arranged locations of the pattern images existing in this image of fixed-point. According to the present invention, displacement and locations of leaf blocks can be detected without making contact, and displacement due to the effect of backlash and gear wear or errors in detecting locations can be prevented. Therefore, regardless of backlash, the locations of the leaf blocks can be detected with high precision, and the radiation field can be matched to the shape of an affected part with high precision.
