Title: Phototimer radiographic device
Inventor: YAMAMOTO SEIICHI
IPC: A61B6/00
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To prevent the adverse effect of an X-ray absorbing amount by a scintillator from appearing on an image while maintaining a sufficient sensitivity to an X-ray. SOLUTION: Part of an X-ray transmitted through a test sample is entered into a plastic scintillator 2 where the X-ray is converted to light. The generated light is allowed to proceed through an acrylate plate 1 as a light guide to be detected by an optical sensor, and if the integral value of the optical sensor output exceeds a specified level, the emission of the X-ray is stopped. In this case, the X-ray absorptive amount of the acrylic plate 1 is almost equal to that of the plastic scintillator 2, so that an X-ray film image formed by the X-ray passing through these parts shows no adverse effect by the difference in the X-ray absorptive amount.

Title: Switching circuit
Inventor: NAKAMURA TOSHIKI
IPC: H03K17/16
Filed: 1992-11-30
Abstract: PURPOSE:To eliminate a transient current unbalance due to deviation in a timing of switches by connecting a transformer whose number of windings of the primary and the secondary sides is identical in series with a series circuit comprising the two switches and a bridge. CONSTITUTION:The winding start point of the primary side of a transformer 4 whose number of windings of the primary and the secondary sides is identical is connected to a voltage source V1 and a winding end is connected to a diode bridge 3. Furthermore, the winding start point of the secondary side is connected to a power supply V2 and its winding end point is connected to the bridge 3 and the transformer windings are connected in series between voltage sources V1, V2. A transient current unbalance takes place due to a deviation in the timing when switches 1, 2 are turned on/off, resulting in causing different currents I1, I2. This change appears as a change in the voltage of the primary winding of the transformer 4 and as a change in the inverted voltage at the secondary side of the transformer 4. Thus, the two voltages are cancelled together in the series circuit of the current path to eliminate the unbalance of the currents I1, I2 due to timing deviation.
