    • In a magnetic recording and reproduction apparatus, for simplifying the structure of a fixing device of an audio-control head and for decreasing the number of adjustment procedures, a synthetic resin part formed of a plate member is molded of a resin integrally with a shaft part extending in a through hole in a base and with a fixed part provided on the opposite surface of the base to the surface of the base on which the plate member is provided, so that the synthetic resin part can be rotated around the through hole; an audio-control head is provided on a head plate, which is pressed toward the base by a spring fitted on a spring fixing screw; and three adjustment screws include screw parts which support the head plate, and cylindrical parts which abut against the surface of the base through holes bored through the synthetic resin part. Positioning of the audio-control head in a moving direction of a magnetic tape is effected by an adjustment jig between a notch on the synthetic resin part and a projection part on the base. Two of the adjustment screws are located on a straight line passing the center of the through hole in the base and the center of a control head, which positions are on the front and rear sides of the control head. Mainly, the height of the audio-control head is adjusted by one of the adjustment screws, the inclination angle .theta. is adjusted by another adjustment screw, and the azimuth angle is adjusted by the other one.
    • 在磁记录和再现装置中,为了简化音频控制头的定影装置的结构并减少调节步骤的次数,由板构件形成的合成树脂部分由树脂一体地与轴部分 在基部的通孔中延伸,并且在基部的相对表面上设置有固定部分到设置有板构件的基部的表面,使得合成树脂部分能够围绕通孔旋转; 在头板上设有音频控制头,弹簧固定螺钉上装有弹簧将其压向基座; 三个调节螺钉包括支撑头板的螺钉部件和与通过合成树脂部件钻孔的基部通孔的表面抵接的圆柱形部件。 音频控制头在磁带的移动方向上的定位是通过合成树脂部分上的凹口和基座上的突起部之间的调节夹具实现的。 两个调节螺钉位于通过基座中的通孔的中心和控制头的中心的直线上,该位置位于控制头的前后两侧。 主要是通过其中一个调节螺丝来调整音频控制头的高度,通过另一个调节螺丝来调节倾斜角度θ,另一个调节方位角。

    • A battery pack with a reduced resistance connection arrangement in which battery cells are arranged in rows in an insulating case and an electrode of each battery cell is coupled to an electrode of another battery cell through a connecting metallic plate. The connecting metallic plate is made of copper and is disposed on a positive electrode of one battery cell and a negative electrode of another battery cell to form a lap joint. Welds are formed in predetermined positions on the connecting metallic plate above the positive and negative electrodes by arc spot welding. The electrodes are formed of nickel-coated steel. The depth h of weld penetration in the weld is greater than the thickness T1 of the connecting metallic plate and smaller than the thickness T1 plus the thickness T2 of one of the electrodes, that is, T1
    • 一种具有减小的电阻连接装置的电池组,其中电池单元在绝缘壳体中排列成排,并且每个电池单元的电极通过连接金属板耦合到另一电池单元的电极。 连接金属板由铜制成,并且设置在一个电池单元的正极和另一个电池单元的负极上,以形成搭接接头。 通过电弧点焊在正极和负极上方的连接金属板上的预定位置形成焊缝。 电极由镀镍钢制成。 焊缝中的焊缝深度h大于连接金属板的厚度T1,小于厚度T1加上电极之一的厚度T2,即T1
