Title: Radiation detection device and radioimaging system using it
Inventor: TAKENAKA KATSURO
IPC: H04N5/32
Filed: 2001-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a radiation detection device enhancing the effect of a mutlilayer electromagnetic wave shield using a multi-layer electromagnetic wave shield while avoiding decrease in sensitivity due to the absorption of radiation by the shield material. SOLUTION: The multilayer electromagnetic wave shield 120 has a metal reflective layer of aluminum 114 and a metal layer of aluminum 116, formed on both sides of a phosphor base a-C115. When a layer of thickness of 10 μm is formed on each of both sides, internal reflection losses become twice as large as would be achieved if the layers are formed with a thickness of 20 μm on only a single side of the phosphor base a-C115, without variation (increase) in the absorption of X-rays, so that the effect of the electromagnetic wave shield can be enhanced. A phosphor CsI113 is formed on a surface to which an optical sensor is bonded, and a phosphor protection layer of polyethylene 112 is formed thereon. An insulating layer of polyethylene 117 is formed on top of the metal layer of aluminum 116. Because the polyethylene is a combination of C(carbon) and H(hydrogen), the rate at which it absorbs X-rays is very low.

Title: Switching circuit for high frequency wave
Inventor: KAWAHISA KATSUE
IPC: H03K17/693
Filed: 2001-03-07
Abstract: PROBLEM TO BE SOLVED: To prevent the reflection of signals inputted from the off-side terminal of a switching circuit for high frequency, and in addition, to realize high isolation between the on-side and off-side terminals of the circuit. SOLUTION: An inductor L1, having an inductance which resonates with a capacitance that acts when a switch element SW1 is turned off, is connected to both ends of the element SW1. Similarly, another inductor L2 is connected to both ends of another switching element SW2. When, for example, capacitances exist at both ends of the element SW1 at the time the element SW1 is turned off, signals leak and pass through the element SW1, but because of the inductor L1, the resistance values at both ends ideally become infinite and the isolation between terminals P1 and P2 is improved.
