  • Publication number: 20020014949
    Abstract: A chip component such as chip resistor, which is capable of being mounted obversely or reversely to a substrate or the like. Since the color of the armor is adjusted so as to be green identical with that of a ceramics chip, the lightness distribution of the component front face is similar with that of the component back face. Therefore, there is no case that chip component mounted obversely and chip component mounted reversely are identified as different components in a testing step of detecting a positional deviation or unloaded component by a color or monochromatic image processing (digital image processing), even if the component is mounted reversely to a substrate or the like.

  • Patent number: 5166553
    Abstract: A semiconductor circuit including first and second FET's for delivering an output signal without being affected by a change in threshold voltage of the FET's is disclosed. According to one practical form of the semiconductor circuit, the drain-source current path of an additional FET whose gate and source are shorted to each other, is connected in parallel to the drain-source current path of the first FET whose gate and drain are shorted to each other, to make the voltage-current characteristic of the second FET agree with that of the parallel combination of the first and additional FET's. According to another practical form of the semiconductor circuit, a voltage dividing circuit is connected in parallel to the drain-source current path of the first FET, and a divided output voltage from the voltage dividing circuit is applied between the gate and source of each of the first and second FET's.
