    • A TIG welding method is usually carried out in a manner that a tungsten electrode is inserted into a weld groove portion of a member to be welded, an electric voltage is applied to a current conducting portion provided for the tungsten electrode while flowing a shield gas means to thereby generate an arc between the tungsten electrode and the member to be welded to form a molten pool of the member, a welding wire is inserted into the molten pool, and a welding torch is then operated to perform a welding process. In the improvement of the TIG welding method, the shield gas means is composed of an inner shield gas flowing from a periphery of the tungsten electrode to a front end thereof inserted into the weld groove portion of the member to be welded and an outer shield gas flowing towards the weld groove angle from an outside of the inner shield gas to prevent the molten pool from being oxidized and to prevent oxygen in air from being involved. The TIG welding torch for carrying out the method is specifically provided with the inner and outer shield gas flow means, and further provided with a central shield gas flow means.
    • TIG焊接方法通常以将钨电极插入待焊接部件的焊接槽部分的方式进行,在设置于钨电极的导电部分上施加电压,同时使屏蔽气体装置 从而在钨电极和被焊接部件之间产生电弧以形成该部件的熔池,将熔丝插入到熔池中,然后操作焊炬进行焊接处理。 在改进TIG焊接方法中,屏蔽气体装置由从钨电极的周边流到其前端的内部屏蔽气体插入待焊接部件的焊接槽部分和外部保护气体 从内屏蔽气体的外侧朝向焊缝角度流动,以防止熔池被氧化并防止空气中的氧气被引入。 用于实施该方法的TIG焊炬具体设置有内外气体保护气体装置,并且还具有中央保护气体流动装置。

    • In a graphic preparing device of the present invention, when a user wants to place an image of post office, which is not stored beforehand, on a road, the picture of the post office is taken by a CCD camera, and is displayed on an additional symbol display position of a symbol display section. When a confirmation key is pressed at a timing when a desirable symbol is displayed on a screen, the displayed image is stored as a symbol. Then, when inside of a frame of the additional symbol display position of the symbol display section is touched with an input pen, and is dragged to a predetermined position on the road, the image of post office as stored as a symbol is displayed on the road, and is stored as a symbol on a map. Namely, the symbol incorporated by the CCD camera is treated in the same way as a common symbol. Also, the frame of the symbol touched with the input pen is enhance-displayed.
    • 在本发明的图形准备装置中,当用户想要将未预先存储的邮局的图像放置在道路上时,邮局的图像由CCD照相机拍摄,并且被显示在 符号显示部分的附加符号显示位置。 当在屏幕上显示期望的符号的定时按下确认键时,显示的图像被存储为符号。 然后,当用输入笔触摸符号显示部分的附加符号显示位置的一帧的内部并被拖动到道路上的预定位置时,将存储为符号的邮局的图像显示在 道路,并作为符号存储在地图上。 也就是说,由CCD照相机并入的符号以与公共符号相同的方式进行处理。 此外,增强了用输入笔触摸的符号的框架。
