摘要： PURPOSE:To obtain a loudspeaker use colored titanium diaphragm being efficient and inexpensive, and also, excellent in an acoustic characteristic by executing a continuous annealing processing to a titanium foil and coloring it after cold rolling, and forming the diaphragm from a colored titanium foil which is obtained. CONSTITUTION:A titanium or titanium alloy foil after cold rolling is annealed continuously in an annealing furnace adjusted to prescribed temperature and gas atmosphere, forming working is further applied as necessary, and a loudspeaker use colored titanium diaphragm colored to a target color is obtained. As for its process, a stock annealing process and a coloring process are executed simultaneously, and also, uniformity of the color is very excellent due to a continuous processing in the annealing furnace in which a gas composition and a temperature are adjusted, and also, there is no variance of a material quality. In such a way, annealing and coloring can be executed continuously in the same process, and a cost reduction can be attained. Also, because of gas atmospheric coloring, coloring which is uniform and always has reproducibility can be executed.

摘要： PURPOSE:To enable the sufficient dewatering of a metal foil strip by arranging a roll by off-setting it on the two directions in the winding direction and vertical-to-face direction of the metal foil strip. CONSTITUTION:Rolls 2, 3 are arranged by separating by a distance G as well as lapping them with the roll offset amt. S in less than the roll diameter D and the superposing amt. in the vertical-to-face direction of a metal foil strip 1 >=zero. At this time, it is preferable to be within the range of L/D; 0.1 min. 0.5 max., S/D; 0.4 min. 0.9 max. and G; 0.1 min. 10mm max. With the above structure, the metal foil strip 1 containing a moisture on the surface by finishing a hot water washing is first brought into contact with a dewatering lower roll 2, the dewatering of the upper face thereof is completely executed and the dewatering of the lower face is completely executed by a contact part B similar to the lower roll 2 by an upper roll 3. Consequently the enough dewatering of the metal foil strip is enabled.

摘要： PURPOSE:To produce a bright annealed titanium sheet material having high quality without being formed with temper colors, etc., continuously with high efficiency by setting the atmospheric pressure of gaseous N2 atmosphere chambers at the pressure lower than the gaseous Ar atmosphere pressure in a furnace body and higher than the out-of-furnace pressure. CONSTITUTION:The atmospheric pressure of the gaseous N2 atmosphere chambers 11, 11' of the continuous bright annealing furnace body 10 is set higher than the out-of-furnace pressure 10 and the gaseous Ar atmosphere pressure in the furnace body 10 is set slightly higher than the atmospheric pressure of the gaseous N2 atmosphere chambers 11, 11'. The pressure to press a coil 3 to be treated to felt 12 is so regulated that some gaseous N2 is ejected from the felt seal in the inlet side chamber 11 to the outside of the furnace 10. The surface of the coil material 3 is cleaned by the ejection flow of such gaseous N2. The O2 sticking to the coil material 3, is therefore, not carried into the furnace body 10 and the generation of the temper colors is prevented. An infiltration accident of the gaseous N2 into the furnace body 10 is prevented even if the pressure in the chambers 11, 11' increases.
