An apparatus for continuously and rapidly forming petal-like segments at the tip of a tampon inserter into a hemispherically curved shape. Sets of molds are mounted on a support table on a rotary table turned about a shaft. Each set comprises a heating mold to heat and soften the tip of the tampon inserter and a cooling mold to shape while being cooled the heated and softened tip. The heating and cooling molds are moved by a cam so that either of the two molds is placed above the tampon inserter held in position by a gripper. The gripper comprises a pair of gripper segments that are opened and closed by a cam on the shaft and raised and lowered by another cam on the same shaft. The cams are adapted to release the tampon inserter from the gripper after the tampon inserter has been put first in the heating mold and then in the cooling mold. The tip of the tampon inserter held by the gripper first enters the heating mold to get heated. While the heated tip descends temporarily, the cooling mold is brought to above the tampon inserter. As the tampon inserter rises again, its tip comes in contact with the inner surface of the cooling mold, in which the tip is formed into a hemispherically curved shape while being cooled.

The present invention provides an apparatus for treating the top ends of flexible cords or filaments. It comprises holding means for holding articles having flexible cords, delivery means for delivering said holding means in a predetermined direction, cylindrical grinding means disposed at a position adjacent to a delivery passage for delivering said holding means, and means for rotating said cylindrical grinding means around its own axis and around an axis at right angles to its own axis. By virtue of the feature that the cylindrical grinding means is rotated around its central axis and around the axis rectangularly crossing the central axis, the top ends of flexible cords, such as bristles of toothbrushes, can be polished and ground from all the directions and very smooth and round outer ends can be obtained at high efficiency and high rate. This effect can be further enhanced when a plurality of such cylindrical grinding members are disposed so that rotation directions of every two adjacent cylindrical grinding means are reversed to each other.

In an automatic screw tightening apparatus, a feed head unit is movable to and from close contact with a driver bit portion. The driver bit portion contacts the screw and sucks the head portion of the screw in close contact. The feed head unit includes a longitudinal groove opened to the outside and connected to a vertically extending screw feed hole. Only a thread portion of the screw is capable of horizontally advancing and retreating in the longitudinal groove.

There are provided a light source device and a display device which do not generate a wrinkle on an optical sheet even if the optical sheet is held on an LED substrate. A reflection sheet is disposed between each of head portions possessed by a rivet, a positioning rivet and a support rivet and one surface of an LED substrate where an LED is mounted, and a gap in a direction of a sheet thickness is provided between the head portion of each of the rivets and the reflection sheet. In the case in which a sudden thermal change is caused, therefore, the reflection sheet expands or contracts between the head portion of each of the rivets and the reflection sheet so that the wrinkle can be prevented from being generated over the reflection sheet.
