A follower fall arrest device used with a fixed safety rope is equipped with a securing system comprising a support arm articulated on a first spindle between an active locking and an inactive unlocking position, a roller in the form of a cylindrical wheel mounted rotating free on a second spindle securedly attached to the support arm, and a centrifugal clutch mechanism arranged between a drive member of the roller and the support arm so as to occupy a disengaged position or an engaged position. The peripheral surface of the roller is equipped with a plurality of studs presenting a predetermined angle of incline so as to cause rotation of the roller in the descending direction, and sliding on the rope in the ascending direction. The body comprises a straight U-shaped channel for passage of the rope, said channel having holes for passage of the attachment means.

A fluid dispenser, including: a receptacle defining a fluid reservoir and an opening; a dispensing member fitted in the opening of the receptacle, and provided with an actuating rod, and a pusher serving to be fitted to the actuating rod of the dispensing member. A trim shell is provided in which an assembly made up of the receptacle and of its dispensing member is adapted to be held in removable manner, and in that the pusher is held captive by the trim shell so that the actuating rod can be connected to the pusher only when inside the trim shell.

The invention relates to a gas supplying unit to be arranged to hermetically fit in an opening formed at a ceiling part of a processing container for conducting a process to a substrate. The gas supplying unit includes a plurality of nickel members. A large number of gas-supplying holes is formed at a lower surface of the gas supplying unit, a process gas is adapted to be supplied from the large number of gas-supplying holes into the processing container, and the plurality of nickel members is fixed to each other via an intermediate member for preventing sticking made of a material different from nickel.

Provided is a sheet processing device including a carry-in path along which the paper sheet is carried in and a retreat path that branches off from the carry-in path, along which at least a part of the paper sheet stored in a stacker section is retreated in a direction opposite to a sheet conveying direction. A bonding means is disposed at a merging point between the carry-in path and retreat path. An adhesive-applied position of a preceding paper sheet is retreated to the retreat path when a next paper sheet is carried in to the stacker section, then the next paper sheet is moved to a bonding position for adhesive application. The above operations are sequentially repeated to generate a paper sheet bundle. Thus, a paper sheet bundle can be generated by bonding the paper sheets using an adhesive, so that it is possible to reduce stress to be applied to the paper sheet as compared to a case where the paper sheet bundle is bound with a metallic staple or by deforming the paper sheets themselves. Further, it is possible to comparatively reduce movement of the paper sheet applied with the adhesive to prevent the adhesive from being adhered to a portion other than the paper sheet, thereby preventing the paper sheets from being bonded to each other at a position other than a predetermined position. As a result, there can be provided a sheet processing device, that is rather small and can bond the paper sheets at a predetermined position.

An electric junction box for use in either a right hand drive vehicle or a left hand drive vehicle. Fuse replacements of the electric junction box are performed through a fuse-replacement opening provided on the vehicle-body side. The electric junction box includes a plurality of fuse-connecting units provided on the case of the electric junction box. The plurality of fuse-connecting units include shared fuse-connecting units located in a middle region among the plurality of fuse-connecting units, fuse-connecting units for a right hand drive vehicle and fuse-connecting units for a left hand drive vehicle. The shared fuse-connecting units aligned with the fuse-replacement opening whether the electric junction box is installed in a right hand drive vehicle or a left hand drive vehicle.

The present invention provides a pin milling cutter formed by combining a cutter and an adapter to prevent errors in attaching a cutter to the adapter even when the cutter is similar but of a different type and even if the engagement section between the cutter and the adapter are the same. A mounting error prevention mechanism is provided on a main cutter unit and an adapter to prevent an erroneous combination of a cutter and adapter from fitting together normally. The mounting error prevention mechanism includes: a projection and a cavity corresponding to the main cutter unit and the adapter and providing a tapered fit; and a projection and a corresponding groove. The projection can be inserted into the groove only when the cutter and the adapter are combined correctly.

The invention relates to a universal objective table for a laser 3D printer. The universal objective table is simple in structure, easy and convenient to operate and control and good in printing effect. The universal objective table comprises a rotary knob, a ball screw, a stretchable connecting ring, a stretchable connecting rod and an objective table body; the top end of the ball screw is connected with the bottom end of the rotary knob through threads, the position, below the rotary knob, of the outer side of the ball screw is sleeved with a spring, the outer side of the spring is sleeved with a fixed connecting sleeve, and the bottom end of the ball screw is provided with the stretchable connecting ring; the bottom end of the stretchable connecting ring is provided with a first hemispheric groove, a first through hole is formed in the middle position of the first groove, and the stretchable connecting ring is arranged on the ball screw in a sleeving manner through the first through hole; the outer wall of the spherical structure at the bottom end of the ball screw is in fit contact with the inner wall of the first groove, and a gap is reserved between the edge of the inner side of the first through hole and the outer wall of the ball screw; and the bottom end of the stretchable connecting ring is connected with the top end of the stretchable connecting rod, the stretchable connecting rod is connected with a protection jacket, and the bottom end of the protection jacket is connected with the top end of the objective table body placed in the horizontal direction.

The invention discloses a laser texturing processing method on the surface of a roller, comprising the following steps: leading the roller to rotate with uniform velocity along self axes; simultaneously, leading a laser texturing head to move with uniform velocity along the axial direction of the roller; and periodically transmitting laser beam to the surface of the roller and forming texturing spots on the surface of the roller. The method is characterized in that by accelerating the moving speed V of the laser texturing head along the axial direction of the roller, the texturing spots are distributed along the high inclination-angle helical line with the thread pitch of delta being equal to 2-200mm on the roller. As the roller has no smooth straight line between the two rows of the texturing spots on the circumference of the surface of the roller, when rolling a steel plate, the roller and the steel plate can prevent from jointing at those parts, the iron slag grains can be absorbedby texturing concave holes crisscross distributed on the peripheral direction of the roller, scratch can not be produced on the length direction of the steel plate, and the iron slag grains can not fray and break the texturing spots, thereby greatly improving the rolling quality of the steel plate and the wearing resistance of the roller, and prolonging the service life of the roller.
