    • The present invention relates to a method of efficiently manufacturing a spotwise partial clad material, which is used for a lead frame of a semiconductor integrated circuit such as a flat package. According to the method, a substrate material to which metal foil pieces having a determined size have been tacked at a highly accurate pitch is prepared by continuously pre-tacking a metal foil as fed at a constant feeding rate to a substrate material as fed also at a constant feeding rate at determined intervals by spot-welding by any of resistance welding, ultrasonic welding or laser welding or thereafter cutting and removing the unnecessary parts by laser-cutting or by the use of rotary cutters, or alternatively, it is prepared by cutting a metal foil as fed at a constant feeding rate with a punch with simultaneously tacking the resulting metal foil piece to a substrate material as fed also at a constant feeding rate by spot-welding of using the punch as an electroconductive material part. The obtained metal-tacked substrate material is pressure-welded and rolled, whereupon the intended and determined thickness of the rolled material is ensured by cascade control for load-constant control and elongation percentage-constant control and the intended load in rolling is controlled by detecting the intended position from the pitch of the rolled material and the intended standard point of the non-rolled material.

    • A method and apparatus for measuring the remaining charge of a galvanic cell effects the measurement of the remaining charge by superimposing an AC voltage or current on DC voltage or current issuing from the cell to produce a higher harmonic current or voltage, determining the value corresponding to a higher harmonic component of n'th order from the higher harmonic current or voltage, and comparing the value thus measured of the cell under test with that measured previously in the same manner of a reference galvanic cell. Since the corresponding value of the higher harmonic current or voltage of n'th order varies notably with the decrease in the remaining charge of the galvanic cell, the comparison of the found corresponding value with the reference characteristic is effected with ease and the measurement can be carried out accurately and simply.
    • 用于测量电池的剩余电荷的方法和装置通过将AC电压或电流叠加在从电池发出的DC电压或电流上产生高次谐波电流或电压来实现剩余电荷的测量,从而确定对应于 从高次谐波电流或电压起n阶的高次谐波分量,并将与测得的电池相同的值与先前参考电流电池相同的方式进行比较。 由于高次谐波电流或第n阶电压的对应值随着原电池的剩余电荷的减少而显着变化,因此可以容易地实现所找到的对应值与参考特性的比较,并且测量可以 精确而简单地进行。

    • A liquid crystal display has pixel electrodes, a common electrode, a liquid crystal layer provided between the pixel electrodes and the common electrode, and a back light that supplies light transmitting through the liquid crystal layer, further has a control circuit that applies a drive voltage corresponding to image data between the pixel electrodes and the common electrode such that the polarity of the drive voltage is inverted for each predetermined period. Within a frame period, the control circuit applies a drive voltage of a first polarity in a first period, applies a drive voltage of a second polarity opposite to the first polarity, which is the same voltage as the drive voltage of the first polarity, in a second period after the first period, and controls such that the back light is turned off in the first period and turned on in the second period.
