Abstract: A laser apparatus for medical treatment use in which a laser beam is irradiated on a portion of a human body to be treated comprises a laser beam generation unit for generating a laser beam of giant pulse, a laser beam guide member having one end through which the laser beam from the laser beam generation-unit is guided, and a hand piece attached to another end of the laser beam guide member and irradiating the laser beam to the portion to be treated. A beam converging point is formed within a laser beam propagating path formed in at least one of the light guiding means and the hand piece and a stay of air is prevented from a predetermined region in the laser beam propagating path including at least the beam converging point at which the air stays. The predetermined region is positioned within the hand piece or the laser beam guide member.

Abstract: Disclosed herein is a spinning nozzle having one or more discharge openings and one or more introduction openings located upstream the discharge openings for producing pitch-based carbon fibers characterized by the presence of one or more spiral members in each introduction openings. According to the nozzle of the present invention, part of the pitch which is introduced to the introduction opening flows down along the spiral member while the flow of the pitch is affected by the spiral member. The remaining pitch flows into the discharge opening without being in contact with the spiral member, and then both are spun after being mixed through the discharge opening to prepare carbon fibers having a random structure. Especially, the carbon fibers of higher performances can be prepared when a spiral having uneven outer diameters is employed.

Abstract: In an optical scanning type system, a laser beam emitted from a laser generator is directed to a mirror which is fixed on a movable pedestal. The laser beam reflected from the mirror is converged on the end face of one of an array of optical fibers by a convergent lens which is also fixed on the movable pedestal. A cam follower is fixed to the pedestal and caused to contact a cam surface of a cylindrical cam body, which defines a number of steps having a stepwise varying height and formed so as to have a predetermined pitch. The cylindrical cam body is coupled to a step motor. The optical fibers are located so as to arrange the end faces thereof at a pitch corresponding to the pitch of the steps. The cylindrical cam body is stepwisely driven so that the cam follower also stepwisely follows the cam surface. Thus, the pedestal is stepwisely shifted and the laser beam is also stepwisely introduced into the optical fibers.
