    • PROBLEM TO BE SOLVED: To provide an induction cooking vessel in which the heat generation elements of a magnetic substance are firmly fixed to a receptacle body of non-magnetic metal.
      SOLUTION: The induction cooking vessel includes the receptacle body 14 and the heat generation parameter 20 of the magnetic substance which heats the bottom of the body 14. Two or more arc-shaped pressure welding elements 11, which are arranged while maintaining space in a circumference direction on each circumference of each radius which gradually becomes large with the center of the bottom as a reference point, are formed on the bottom of the body 14. Each heat generation elements 20 includes two or more first induction parts 24 radially extended and two or more second induction parts 26 which intersect with each of the first induction parts 24 and are arranged concentrically, and an insertion aperture 22, which is surrounded by space between two adjacent first induction parts and space between two adjacent second induction parts, is formed. The two or more pressure welding elements 11 prepared on the bottom of the body 14 are inserted into the respective insertion apertures 22 of the heat generation element 20 and then the pressure welding elements 11 are plastically deformed by press working and then fixed to the bottom of the body 14.

    • A display apparatus including a display driver. The data driver includes a converter to receive and convert image data in digital form into data voltages in analog form, and to provide the data voltages to output buffers. The output buffers receive and buffer the data voltages based on bias voltages generated as part of a feedback path between a bias voltage control circuit and the output buffers. The data voltages are provided to a display part. Before the data voltages output from the output buffers are provided to the display part, the bias voltage control part receives data voltage from the output buffers to count a slew rate of the data voltage, and varies the voltage level of the bias voltage based on the counted result of the slew rate, thereby providing feedback to the output buffers. Accordingly, differences of the slew rate between the data voltages output from the output buffers may be decreased.
    • 一种显示装置,包括显示驱动器。 数据驱动器包括用于以数字形式接收图像数据并以模拟形式将其转换为数据电压的转换器,并将数据电压提供给输出缓冲器。 输出缓冲器基于作为偏置电压控制电路和输出缓冲器之间的反馈路径的一部分而产生的偏置电压来接收和缓冲数据电压。 数据电压被提供给显示部分。 在从输出缓冲器输出的数据电压被提供给显示部分之前,偏置电压控制部分从输出缓冲器接收数据电压以对数据电压的转换速率进行计数,并且基于该偏置电压来改变偏置电压的电压电平 计算转换速率的结果,从而向输出缓冲器提供反馈。 因此,可以减小从输出缓冲器输出的数据电压之间的转换速率的差异。
