    • A video signal interpolation can adapt an image of input video signal to voluntary aspect ratios widely. The invention also allows a display device to uniformly line-sequential scan and uses at least two line-memories (LM1, LM2) which are applied with an input digital video signal and controls writing and reading for these line-memories to generate a video signal subjected to vertical interpolation from a reading output of the line-memories. In the control, any one of the line-memories are circularly selected, and a sample sequence of the input digital video signal is sequentially written into the selected line-memory at its sample rate while sequentially reading out samples of the written sequence at a constant rate which is higher than the sample rate and which is according to a desired ratio of interpolation (vertical expansion ratio), wherein, when one of the line-memories is in writing operation, the other one of the line-memories is repeatedly read out. The invention also relates to a horizontal interpolation method for a video signal.
    • 视频信号插值可以将输入视频信号的图像广泛地适应自愿长宽比。 本发明还允许显示设备均匀地进行行顺序扫描,并使用至少两个线路存储器(LM 1,LM 2),其被施加输入数字视频信号并且控制这些行存储器的写入和读取以产生 视频信号从行存储器的读取输出进行垂直内插。 在该控制中,循环选择行存储器中的任何一个,并且输入数字视频信号的采样序列以其采样率被顺序地写入所选择的行存储器中,同时以恒定的顺序读出写入序列的采样 速率高于采样率,并且根据期望的内插比率(垂直扩展比),其中当行存储器之一处于写入操作时,重复读出另一行行存储器 。 本发明还涉及一种用于视频信号的水平内插方法。

    • The present invention provides a die for superplastic forming of titanium-based alloy with high-workability, which is inexpensive and easy to handle, and has detailed shape-reproducibility and no reactivity with titanium-based alloy to be processed, and has excellent accordance with it in a thermal expansion coefficient. This invention relates to a die for superplastic forming of titanium-based alloy characterized by comprising quartz, cristobalite and calcium silicate. The above die for superplastic forming of titanium-based alloy is produced by kneading a mixed powder of quartz and cristobalite, together with a binder containing a plaster additive of less than 30 weight % based on the total amount with water, forming the mixture, drying the formed product and sintering it in the atmosphere to convert the plaster additive into calcium silicate.
