    Abstract: PURPOSE: Provided are a burner for synthesizing glass particles which is a concentric multi-tubular burner easy to be manufactured, which is high in efficiency of mixture among raw material gas, combustion-support gas and combustible gas, and which can obtain a high raw material yield, and a method for producing the porous glass body by use of the burner. CONSTITUTION: The concentric multi-tubular burner for synthesizing glass particles, comprises a center port group(5) including: a raw material gas jet port(1); a combustible gas jet port; and an oxygen gas jet port(4) disposed outside the raw material gas jet port and combustible gas jet port. An outer wall of the oxygen gas jet port of the center port group more protrudes toward a head of the burner than an inner wall of the oxygen gas jet port, and a protruding length of the outer wall is not shorter than 30 times as large as a gap between an inner surface of the outer wall and an outer surface of the inner wall of the oxygen gas jet port.

    Abstract: Provided are a magnesium alloy plate excellent in a warm-plastic workability, its manufacturing method, and a worked member prepared by warm-plastic working the plate. The magnesium alloy plate is manufactured by applying a predetermined distortion to a rolled material (RS), which is not subjected to a heat treatment for recrystalization, and by not performing that heat treatment even after the distortion was applied. The distortion application is performed by heating the rolled material (RS) in a heating furnace (10), and by passing the heated rolled material (RS) between rollers (21) thereby to bend the rolled material (RS), so that the bent plate may have a half value width of the (0004) diffraction peak in the monochromatic X-ray diffraction, at 0.20 deg. to 0.59 deg. This alloy plate utilizes the residual distortion to cause a continuous recrystalization in the warm-plastic working operation thereby to manifest a high plastic deformability.
