A touch sensor has an LC oscillator circuit 1, 2, 3, and 4, a rectification circuit 10 which rectifies outputs of the oscillator circuit 1, 2, 3, and 4, a voltage detection circuit 12, 13, 14, and 15 which detects the rectified voltage, and a sensor plate 8 connected to the input section of the rectification circuit, and detecting contact of a finger with the sensor plate 8 by enabling the voltage detection circuit 12, 13, 14, and 15 to detects a drop of equivalent impedance due to a finger touching the sensor plate 8 as a change of voltage.

A new compound, named 'Griseolic acid', and its salts and can be prepared by the cultivation of Streptomyces griseoaurantiacus SANK 63479 (FERM-P 5223). Griseolic acid and its salts inhibit the activity of the enzyme cyclic adenosine monophosphate phosphodiesterase and, as a result of this, have variety of physiological activities and uses.
