摘要： There is offered a signal processing circuit for an electrostatic capacity type touch sensor capable of detecting a larger number of locations with a smaller number of touch pads as well as improving noise immunity. A selection circuit selects either a signal from a combination of the first and second kinds of touch pads outputted through the first and second output terminals CO1 and CO2 in a touch panel or a signal from a combination of the third and fourth kinds of touch pads outputted through the third and fourth output terminals CO3 and CO4. An electric charge amplifier outputs first and second output voltages V1 and V2 corresponding to a difference between capacitances of the touch pads on the touch panel based on the signals from the selected combination. A delta sigma type A/D converter converts the first and second output voltages V1 and V2 into digital signals.

摘要： A method of treating an aluminum-wheel surface for removing an alkaline material without damaging the aluminum surface to improve the adhesion of a coating to the aluminum base material. The method achieves a corrosion resistance equivalent to that obtained by treatment using chromic acid chromate containing hexavalent chromium, without adversely affecting the health of workers and the environment. The method includes a blasting process for blowing a casting material onto the aluminum-wheel surface. The casting material includes plastic particles ranging in size from 100 to 2000 μm and containing a thermosetting resin as the main ingredient.
