Abstract: PROBLEM TO BE SOLVED: To provide a resin molded product producing method and apparatus capable of enhancing the transfer efficiency of a resin sheet and the yield of a resin molded product. SOLUTION: A resin molded product producing method includes a process for transferring a resin sheet 1 in a constant direction, a process for the molding processing of the transferred resin sheet 1, a process for cutting the molded resin sheet 1 to separate the same into a resin molded products 7 possible to laminate and a process for laminating the resin molded products. In this case, when the resin sheet 1 is transferred to be subjected to molding processing and the molded sheet is cut to be separated into the resin molded products 7 and these products 7 are irradiated with X-rays, X-rays transmit through the resin molded products 7 and air in the vicinity of the upper and rear surfaces of the resin molded products 7 is ionized to collectively and uniformly destaticize the resin molded products 7. Therefore, the mutual shift of the resin molded products 7 caused by electrostatic repulsion is prevented when the resin molded products 7 are laminated and it is prevented that the resin molded products are partially melted or scorched by the discharge between the resin molded products.

Abstract: PROBLEM TO BE SOLVED: To provide an X-ray generator that can produce X rays over a longer time and with stability, by operating an X-ray tube efficiently irrespective of the usage conditions. SOLUTION: The X-ray generator 1 comprises the X-ray tube 11, having a cathode part 16, a grid electrode 15 and a target 22, a voltage controller 27 and 32 for controlling the voltages applied to the cathode part 16 and the grid electrode 15, and switches 33 and 34 for switching on and off the X-ray generator 1 and X-ray emission. The voltage controller 27 and 32 applies a positive standby voltage Vf1 to the cathode part 16 and applies a negative cutoff voltage Vc1 to the gird electrode 15, according to an on signal to the X-ray generator 1 and an off signal to X-ray emission. According to the on- signal to the X-ray generator 1 and the on-signal to X-ray emission, a cathode- operating voltage Vf2 higher than the standby voltage Vf1 is applied to the cathode part 16, and a grid-operating voltage Vc2 higher than the cutoff voltage Vc1 is applied to the grid electrode 15.

Abstract: PROBLEM TO BE SOLVED: To provide a scanning electron microscope which allows observing the contour of a sample clearly. SOLUTION: A sample OBJ placed inside a scan range is scanned by an electron beam EB. A secondary electron detector 18 detects secondary electrons emitted to the surface of the scan range and outputs a detection signal B. Charged particles or the like that pass to the back of the scan range are detected by a transmitted electron detector 20, which then outputs a detection signal A. A binarizing circuit 28 forms a binary signal AHL according to the detection signal A. A background eliminating circuit 26 switches a switching element 26a according to the logic level of the binary signal AHL, thereby eliminates information in the detection sample A about scanning of areas other than the sample OBJ, sets the detection signal A to ground potential, and transfers the signal to an image signal forming circuit 26b, to cause a display device 30 to display a reproduced image. Because the background information is eliminated, an image of the subject OBJ is reproduced and displayed clearly.
