    摘要: A chip component feeder which has high feeding efficiency feeds chip components individually in stable orientations. The separating feeder of the present invention includes a scattering disk disposed so that the top surface thereof is inclined with respect to a horizontal plane, a transferring groove formed on the scattering disk and a cavity formed at an outer peripheral end portion of the scattering disk. When the scattering disk is rotated, chip components are dropped into the transferring groove and are aligned in a predetermined direction. After the chip components are accommodated in the cavity by gravitational force (i.e., by upward rotation of the transferring groove), separation of the chip component in the cavity from the chip components in the transferring groove can be achieved.

    摘要: In respective comparators, a plurality of input voltages are compared with a comparison voltage that has been swept, and only the binary output of a D flipflop corresponding to the comparator that has exceeded the comparison voltage earliest is allowed to have "1", while the outputs corresponding to the rest of the comparators have "0". Therefore, it is possible to detect a maximum output by using the comparators of a normal CMOS construction and a binary-change detection means circuit constituted by logical circuits. Compared with the application of floating-gate MOS, this arrangement makes it possible to reduce costs, and also to easily carry out offset-voltage compensation for each comparator by using switched capacitors. As a result, in a maximum input detector which detects a maximum input from analog inputs through multiple channels by carrying out analog operations, it is possible to reduce costs, and also to improve detection precision.

A decoding section estimates on the basis of a first inner product operation of the outputs and the code sequences a first capacitance value and on the basis of a second inner product operation of the outputs and the code sequences a second capacitance value. A touch panel has a two-dimensional region including a hand placing region and a remainder region and processing sections.
