  • Publication number: 20190056455
    Abstract: A circuit is formed by connecting an external power source to a charged electrical storage device so that a polarity of a voltage of the external power source is reverse to a polarity of a voltage of the charged electrical storage device, and the voltage of the external power source is adjusted so that a current does not flow right after the connection. Then, current measurement to acquire a current value after convergence of the current flowing through the circuit due to a voltage drop of the electrical storage device and quality determination based on the current value after convergence are performed. In the current measurement, resistance measurement to actually measure a circuit resistance and prediction to predict a convergence timing of the current based on the actually measured circuit resistance are performed. The current value is acquired when a predicted convergence timing comes.

  • Publication number: 20190041466
    Abstract: An external electric power supply is connected to a charged electric power storage device in a reverse voltage direction to form a circuit. A voltage of the external electric power supply is adjusted such that a current does not flow immediately after the connection. Then, current measuring of acquiring a converged current value of the current in the circuit due to a decrease in the voltage of the electric power storage device, and quality deciding based on the converged current value are performed. Before the quality deciding, the electric power storage device is grouped such that the converged current value of when the electric power storage device is a normal product is constant in a group. In the quality deciding, a degree of variation in the converged current value is calculated for each group, and the quality is determined by comparing the calculated degree of variation with its predetermined level.

  • Patent number: 9485457
    Abstract: This invention enables, for example, reduction of motion blur in a hold-type display device and reduce flicker in an impulse-type display device by a simple process. For this purpose, an LPF filters a frame of input image data (A[i]) to generate low-frequency image data (L). A subtractor and an adder generate high-frequency image data (SH). Another adder adds the low-frequency image data (L) from a delay circuit to subsequent low-frequency image data. A divider halves the sum to generate low-frequency averaged image data (SL). A switch alternately outputs the high-frequency image data (SH) and the low-frequency image data (SL) every time a frame of image data is input. As a result, the apparatus of this invention can generate output image data having a frame rate twice that of the input image data.
