Abstract
Abstract A solid-state image converting device wherein the luminescence of a luminescent element is controlled by the variation in the impedance of an energy sensitive element with incident energy. The energy sensitive element is a composite element comprising a highly sensitive and highly responsive element and a high resistance and high breakdown voltage element, whereby a highly sensitive and highly responsive device to which a sufficient operating voltage can be applied is provided.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
125 words
A solid state image converting device comprising a pair of electrodes, a composite energy sensitive element and an electrically luminescent element, both of said elements being disposed adjacent to each other and interposed closely between said pair of electrodes, wherein one of said pair of electrodes which rests on said composite energy sensitive element is a foraminous electrode and said composite energy sensitive element is composed of a first energy sensitive element adjacent said foraminous electrode and a second energy sensitive element adjacent said electrically luminescent element, the response to said first element to incident energy being more rapid than that of said second element, and the dielectric strength and the dark impedance of said second element being higher than those of said first element.
Claim 2
Dependent Claim
125 words
A solid state image converting device comprising a pair of electrodes, a composite energy sensitive element and an electrically luminescent element, both of said elements being disposed adjacent to each other and interposed closely between said pair of electrodes, wherein one of said pair of electrodes which rests on said composite energy sensitive element is a foraminous electrode and said composite energy sensitive element is composed of a first energy sensitive element adjacent said foraminous electrode and a second energy sensitive element adjacent said electrically luminescent element, the response to said first element to incident energy being more rapid than that of said second element, and the dielectric strength and the dark impedance of said second element being higher than those of said first element.
Claim 3
Dependent Claim
23 words
A solid state image converting device according to claim 1, wherein said foraminous electrode comprises a parallel-grid electrode made of fine metal wire.
Claim 4
Dependent Claim
