    摘要： 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. The air stay is prevented by means of producing a vacuum state, gas seal state or air flow state in the predetermined region.

    摘要： A method for producing pitch-type carbon fiber, comprising the steps of discharging, from a spinning nozzle, a spinning pitch comprising an optically isotropic pitch and/or optically anisotropic pitch, maintained at such a temperature that the spinning pitch can have a viscosity of 20 poises or less, to form pitch fiber, while jetting a gas preheated to a temperature of 100.degree. C. lower than the temperature at which the spinning pitch can have a viscosity of 20 poises or less, or higher from the periphery of the spinning nozzle in the same direction as the discharging direction of the spinning pitch and parallel to the discharged pitch fiber to give extremely fine fiber having an average diameter of 5 .mu.m or less, and subjecting the thus spun fine fiber to infusibilization and carbonization.
