Title: Inverter
Inventor: YOSHIDA KAZUO
IPC: H05B41/24
Filed: 1992-11-13
Abstract: PURPOSE:To make it possible to adjust power supplied to a load without fluctuating a frequency, and lighten a discharge lamp, as a load, stably in a deep dimming state. CONSTITUTION:A set of serially connected switching elements S1 and S2 or S3 and S4 is connected to a DC power supply. An inductor L1, a capacitor C2, and a load (Z) are connected between each middle point of the switching elements S1 and S2 or S3 and S4. The switching elements S3 and S4 have a on-off timing range that is changed from the same phase to a 180-degree shifted phase with respect to a range of the switching elements S1 and S4. The concurrent on-state time of of the switching elements S1 and S4 or S2 and S3 provided diagonally is changed so that the amount of power supplied to the load (Z) can be adjusted without shifting a switching frequency. In this case, the switching frequency of the switching elements S1 and S4 or S2 and S3 is made different so as to supply a DC factor to the load (Z) while power with imbalance between the positive and negative is fed to a resonance circuit. Consequently, when the load (Z) is, for example, a discharge lamp, the discharge lamp is prevented from going out and a flickering state by shifting strips can be reduced.

Title: X-ray inspection device
Inventor: YUKI TAKAHIRO
IPC: G01N23/04
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To provide an X-ray inspection device equipped with a function to exclude the influence of a supporting member for a stimulable phosphor upon the photographed image of back scattering X-rays. SOLUTION: X-rays 6 are applied on a base board (object to be inspected) 3, and the portion having passed through the board 3 is incident on a stimulable phosphor 4. A load plate (high shutoff material) 2 for X-rays is installed downstream in the X-ray irradiating direction of the phosphor 4, i.e., parallel with the surface opposite the X-ray incident surface. Because the X-rays having penetrated the phosphor 4 are shut off by the lead plate 2, they do not reach the structural member which supports the phosphor 4 in the specified position, and it is possible to prevent the X-rays having penetrated from being scattered by the structural member and put again incident on the phosphor 4.  When other beams of X-rays than those having passed the base board 3 are incident on the phosphor 4, the resolution of the X-ray transmission image accumulated in the phosphor 4 may be degraded, but the above configuration well prevents it and precise X-ray inspection can be performed.

Abstract: PURPOSE:To carve a detailed pattern by printing a pattern on the surface of a stone material and forming the elastic film of an ink agent to the stone material after the ink agent is solidified and grinding the surface part not covered with the elastic film of the stone material by blast treatment. CONSTITUTION:A screen having an image printed thereon is placed on the upper surface of a stone material 6 and an ink agent 7 is applied to the upper surface of the screen. After the ink agent 7 is solidified, the screen is removed to partially form the elastic film 8 of the ink agent 7 on the surface of the stone material 6. Subsequently, by subjecting the stone material 6 having the elastic film 8 to sand blast treatment, the surface part not covered with the elastic film 8 of the stone material 6 is eliminated by sand to become a recessed part and the surface part covered with the elastic film of the stone material 6 repels sand to generate no release. As a result, the surface part covered with the elastic film 8 of the stone material 6 becomes a protruding part without being ground. The elastic film 8 on the surface of the stone material 6 is removed by a chemical method, a knife or washing. By this method, a detailed pattern can be carved.
