    • A body frame for a motor bicycle includes a main frame, a head tube provided at a front end of the main frame and down tubes extending rearward from the main frame. The main frame, head tube and down tubes are cast with a light alloy into an integral form of a hollow and thin-wall structure. A production process of the body frame, wherein an integrally-formed core, which is formed into a shape similar to that of the body frame, is hollow and has good permability. A molten metal is charged into the mold and a vacuum is applied to the interior of the core. The molten metal is charged into a cavity defined between the core and the molding surface of the mold by a low-pressure casting method, and the molten metal is solidified so as to cast the body frame. A production apparatus of the body frame includes a liftable cope fitted to a vertical casting machine, a fixed drag, and slidable molds disposed in combination with the cope and being capable of horizontally sliding in a state that the cope is released from the drag. A body frame having both properties of light weight and high stiffness, and a production process and apparatus thereof is provided wherein casting defects and to provide a high-precision cast article, is provided.
    • 一种用于摩托车的车身框架包括主框架,设置在主框架前端的头管和从主框架向后延伸的下拉管。 主框架,头管和下管以轻合金铸造成中空和薄壁结构的整体形式。 主体框架的制造方法,其中形成为与主体框架类似的形状的整体形成的芯部是中空的并且具有良好的可容许性。 将熔融金属装入模具中,并将真空施加到芯部的内部。 将熔融金属通过低压铸造法加入到芯体和模具的成形表面之间的空腔中,并使熔融金属固化,从而铸造主体框架。 主体框架的制造装置包括安装在垂直铸造机上的可升降的上座板,固定的拖曳和可滑动的模具,与所述上座组合配置,并且能够在所述上钩从所述拖曳中释放的状态下水平滑动。 提供了具有轻质量和高刚度的两种特性的车体框架及其制造方法和装置,其中提供铸造缺陷并提供高精度铸造件。

    • A thermally sensitive recording head comprising, a two bases 2 moving with its attitude being kept along a guide shaft 5, an attachment 3 rotatably provided on the base 2 so that the base 2 extends to an right angle direction with the guide shaft 5 and contacts on or separates from a platen 8, and a heating head 4, which is rotatably provided on the attachment 3, and on front surface of which a heating body train is formed in a right angle direction with the guide shaft 5 and extends in opposite direction to an extending direction of the attachment 3 from the tip end of the attachment 3 to contact on or separate from the platen 8, whereby the attachment 3 and the heating head 4 are pressed on the thermally Sensitive paper placed on back-side of the platen 8. In this arrangement, a clear image can be obtained without generation of irregularity of photographic density because the heating head 4 presses the thermally sensitive papers while being kept always in parallel with the platen 8.
    • 一种热敏记录头,包括:沿着导向轴5保持其姿态移动的两个基座2;可旋转地设置在基座2上的安装件3,使得基座2与导向轴5成直角的方向延伸, 与压板8分开或分离;以及可旋转地设置在附件3上的加热头4,并且其前表面上与导向轴5成直角方向形成加热体列,并沿相反方向延伸 从连接件3的前端延伸到连接件3的延伸方向上,以与台板8接触或分离,从而将附件3和加热头4按压在放置在压盘背面的热敏纸上 在这种布置中,可以获得清晰的图像而不会产生不均匀的照相密度,因为加热头4在保持总是与压板8保持平行的同时按压热敏纸。
