The present invention provides a solid state image sensor and a camera using such a solid state image sensor, in which all of stage registers of the shift register can be reset efficiently without increasing the number of pads andor sensor pins. The above process is capable of producing bisphenol A at high conversion and selectivity by suppressing deterioration of catalytic activity due to methanol as an impurity in acetone. A tunable filter is connected to the top of the bench and filters an optical signal transmitted by the fiber pigtail.
