Abstract

DC60 (13/10/54) The transducer has a light-emitting part that emits incident light that passes through the An insulating shield and a light receiving unit that receives the reflected light reflected by the incident light on the surface of the Insulation separator layer The light-emitting unit has the first light-emitting part in the ring state, which It emits incident light so that its angle from the surface of the insulating base layer is 25 ํ or less. And the second light-emitting part in a ringed state, which emits incident light so that its angle from the surface of The insulating base layer ranges from 35 to 65 ํ. The detector has a light-emitting element that emits incident light that passes through the An insulating shield and a light receiving unit, which receives the reflected light reflected by the incident light on the surface of the Insulation separator layer The light-emitting unit has the first light-emitting part in the ring state, which It emits incident light so that its angle from the surface of the insulating base layer is 25 ํ or less. And the second light-emitting part in a ringed state, which emits incident light so that its angle from the surface of The insulating separator base layer ranges from 35 to 65 ํ.
